6 1. Introduction Congratulations! You have purchased one of world s best products in the3 axis mobile satellite communication antenna product line the SuperTrack Z12 MKⅡ. This system, along with your satellite modem, will deliver the best communication possible using state of art antenna control technology. Your Z12 MKⅡ Series system is a fully stabilized antenna that has been designed and manufactured so as to be inherently reliable, easy to maintain, and simple to operate. Except for start ups, or when changing to operate with different transponders or satellites, the equipment essentially permits unattended operation. 1.1 Purpose Satellite service originates from an uplink facility on Earth the facility receives many signals from different sources, combines the signals digitally and transmits to the satellites. The satellites (22,300 miles above Earth) receive the uplink signal, amplify it and then transmit it back to earth in the Ku frequency band. This signal is concentrated and reflected to the LNB located at the back of the dish. The LNB amplifies and converts the signal to the 950 to 2050MHz range. The signal is then passed through a coaxial cable to the modem where high speed internet and voice communication take place. This shipboard Transmit Receive (TXRX) system provides you with two way satellite voice/data communications while underway on an ocean going vessel. This can be used to provide a wide variety of telephone, fax and data applications. Your Z12 MKⅡ Series Antenna system can transmit to and receive from any desired satellite which has adequate signal coverage in your current geographic area. The antenna may be fitted with appropriate Transmit & Receive RF Equipment and appropriate Feed to allow you to operate in linear polarization mode at and Ku Band frequencies. This input will be distributed to your satellite modem and then to all of your other below decks equipment. 1.2 System Components The SuperTrack Z12 MKⅡ system consists of two major groups of equipment; an above decks group and a below decks group. Each group is comprised of the items shown, and listed, below. All equipment comprising the Above Decks is incorporated inside the radome assembly and is integrated into a single operational entity. For inputs, this system requires only an unobstructed line of sight view to the satellite, Gyro Compass input and AC electrical power. For more information about these components, refer to the Basic System Information section of this manual. A. Above Decks Equipment (ADE) Group 1. 3 axis stabilized antenna pedestal 2.

10 2. Installation We hope this section will provide clear instructions to install the SuperTrack Z12 MKⅡ. Installation of your SuperTrack Z12 MKⅡ Series Antenna system must be accomplished by or under the supervision of an authorized KNS dealer for the KNS Limited Warranty to be valid and in force. Good planning of the installation will provide the best results. Below is some guidance on issues that are important to consider when planning the installation. Planning is the button to a good installation. Read the installation information below thoroughly before beginning the actual installation. Then review your plan to adjust for any details that may have been overlooked. 2.1 Site Selection Determine the optimum mounting location for the antenna radome assembly. where: It should be installed 1. The antenna has a clear line of sight view to as much of the sky as is practical. Choose a location where masts or other structures do not block the satellite signal from the dish as the ship turns. 2. The antenna is at least 5 feet away from other transmitting antennas (HF, VHF and radar) that may generate signals that may interfere with the SuperTrack Z12 MKⅡ Series antenna. The further away the SuperTrack Z12 MKⅡ antenna is from these other antennas, the less impact their operation will have on it. 3. Direct radiation into the antenna from ships radar, especially high power surveillance radar arrays, is minimized. The radome should be as far away from the ships Radar as possible and should NOT be mounted on the same plane as the ships Radar. 4. The antenna radome assembly should be rigidly mounted to the ship. If necessary, reinforce the mounting area to assure that it does not flex due to the ship motion or vibration. If these conditions cannot be entirely satisfied, the site selection will inevitably be a best compromise between the various considerations

11 2.2 Unpacking the Unit Open wood box using pliers and remove packing material carefully. Lift unit out of box carefully. Do not turn box and roll out, or turn upside down to remove. Carefully inspect the radome panel surfaces for evidence of shipping damage. Inspect the pedestal assembly and reflector for signs of shipping damage. Be careful when unpacking the equipment.

16 2.3 Prepare ADE & BDE Mounting Location Prepare the mounting location for the radome. Check radome support post and assure that the mounting holes have been drilled correctly. Prepare the mounting location for Below Decks Equipment. These equipments would normally be installed in a standard 19 equipment rack. Refer to the Antenna Control Unit section for installation of the ACU and the Terminal Mounting Strip. Refer to the vendor supplied manuals for installation of the other below decks equipments. Prepare other locations throughout ship for any other equipment which is not co located with the ACU. 2.4 System Cables Installation The system is comprised of two major sections: The Above Decks Equipment (ADE) is comprised solely of the antenna radome assembly which is mounted outside, on the ships upper deck or mast location chosen for best satellite reception. The Below Decks Equipment (BDE) includes the Antenna Control Unit(ACU), satellite modem(s) and all other ancillary equipment that is mounted in various locations throughout the interior of the ship. The two cables must be routed from the ADE group through the deck and through various ship spaces to the vicinity of the BDE group. When pulling the cables in place, avoid the use of excessive force. Exercise caution during the cable installation to assure that the cables are not severely bent (proper bend radius), kinked or twisted and that connectors are not damaged. Assure that the cables have been run through watertight fittings and/or will not permit water entry into the ship when the installation is completed. After cables have been routed and adjusted for correct cable length at each end, seal the deck penetration glands and tie the cables securely in place

17 2.5 Antenna Unit Mounting Preparing the Radome Assembly 1. The SuperTrack Z12 MKⅡ antenna pedestal is shipped completely in its single piece radome. 2. Remove the shipping hold down bolts which mount the radome to its pallet. 3. Attach a four part lifting sling to the four lifting eyes in the base of the radome and lift the radome assembly free of its shipping pallet. Place the radome assembly on temporary support blocks. 4. Carefully inspect the radome panel surface for evidence of shipping damage. Inspect the pedestal assembly and reflector for the sign of shipping damage. 5. Using the four part lifting sling, and with a tag line attached to the radome base frame, hoist the antenna assembly to its assigned location aboard ship by means of a suitably sized crane or derrick. 6. The radome assembly should be positioned with the BOW marker aligned as close as possible to the ship centerline. Any variation from actual alignment can be compensated with the RELATIVE ANGLE SETTING adjustment in the ACU, so precise alignment is not required. Refer to Relative Angle Setting Section of Operation Menu for detail adjustment. 7. Bolt the radome base frame directly to the antenna support post from below. 8. Disconnect the lifting sling from the four eyes in the base of the radome. (unit : mm) Figure 2-7 Radome Mounting Hole Diagram

18 Figure 2-8 Radome Diagram

19 Preparing the Radome Support Post 1. Prepare Antenna Support Post for radome. The radome will be bolted to the support post plate. Assure that mounting holes have been drilled. Assure that the mounting hardware has obtained and is readily available. 2. Make certain that the antenna support post should be painted appropriately for anti corrosion. 3. Bring the TX and RX cables from below decks up through the cable access hole on the deck. (Check the number of RF cables required). 4. The support post should be is upright. Check post angle carefully prior to welding post base to deck. If uneven or not level, weld clips to the plate or place the foam seal in position on the mounting surface. 5. Refer to Appendix A: for more detail drawings. (unit : mm) Figure 2-9 Typical Antenna Support Post Diagram

20 Hoist Hoisting with other than a webbed four part sling may result in catastrophic crushing of the radome. Refer to the specifications and drawings for the fully assembled weight of your model antenna and assure that equipment used to hoist his system is rated accordingly. The antenna assembly is very light for its size and is subject to large swaying motions if hoisted under windy conditions. Always ensure that tag lines, attached to the radome base frame, are attended while the antenna assembly is being hoisted to its assigned location aboard ship. 1. Assure that the antenna is restrained before hoisting. Check that all nuts on the base frame assembly are tightened according the torque values mentioned above. 2. Using a four part lifting sling, and with a tag line attached to the radome base frame, hoist the antenna assembly to its assigned location aboard ship by means of a suitably sized crane or derrick. Figure 2-10 Antenna Hoisting 3. The radome assembly should be positioned with BOW marker aligned as close as possible to the ship centerline. Any variation from actual alignment can be compensated with the Relative Angle Setting in the ACU so precise alignment is not required

21 Figure 2-11 Radome Positioning

22 Install Radome Bolt radome from below. When completed the radome base must be level. Figure 2-12 Bolting Radome/Antenna Note : The SuperTrack antenna must kept out of line with nearby radars, as their energy levels may overload the antenna s front end circuits. In an ideal installation, the antenna is mounted four feet (1.2m) above and four feet (1.2m) away from the radar (measured from the center of the antenna dome to the center of the radar). The best placement for the SuperTrack antenna is above the radar. However, if there will be a significant horizontal separation between the radar and antenna dome (i.e., at least 8 to 10 feet (2.5 to 3m)), the SuperTrack antenna can be placed below the radar as there will be little chance of signal blockage

23 Remove Antenna Holding Ties Remove wire ties holding Antenna Unit and the foam shipping restraints. Rotate the antenna smoothly to check any shipping restrains remained from the Antenna Unit. When rotating the azimuth mechanism by hand, go slowly. Figure 2-13 Removing Antenna Holding Ties through Hatch Door

24 Install TX/RX Cables Drill two cable access holes at the Radome base. Make certain that pre installed TX/RX cables is close to access holes before drilling. Smooth the edge of the cable access hole and install Cable Grand to protect cables Typical Cable Grand Bring the TX/RX cables through the cable access holes and connect TX/RX cables to the connectors of antenna. Check label both ends of each RF cable to match its radome base plate connector. Do not use Teflon gel on the cable fittings as it reduces signal strength at high frequencies Connection TX/RX Cables

25 Figure 2-16 Antenna on the Support Post

26 2.6 GPS Installation The GPS Antenna System is standard equipment for SuperTrack Z12 MKⅡ. The GPS Antenna System consists of GPS antenna and receiver. The GPS antenna attaches directly to the top mounting plate of Antenna Unit and GPS receiver is installed inside Antenna Control Box that is attached to the azimuth post. GPS antenna cable is tied along with Antenna bracket to prevent interference with Antenna movement. When GPS installed, Antenna Unit will check GPS module automatically. Figure 2-17 GPS Module Installation

27 2.7 ACU Mounting Install the ACU in the front of the standard 19 equipment rack or other suitable location. ACU Figure 2-18 ACU Installation

28 2.8 Install the ACU Cables There are several functional connections that may be made on the various connectors. You may not need to make all of these connections, but they are listed here for you to decide which ones you do need to make during installation. RX IN I/O Strip & Gyro RX OUT Power Cord Gyro Port TX IN NMEAOUT M&C TX OUT Console Air Flow Out Figure 2-19 ACU Rear View Gyro Use this connector to connect synchro gyro, step by step gyro, and NMEA output of Gyro compass to the ACU. For analog Gyro compass output, Gyro strip and port can be used. Don t use Gyro strip and Gyro port at the same time. It can damage ACU. Refer to Gyro Compass Interface section

29 Figure 2-20 Gyro Connector Use RX+ and RX when NMEA output of Gyro compass is RS488. If NMEA output of Gyro compass is RS 232C, then short RX+ to ground and connect RX to NMEA data port. TX+ and TX are reserved for future upgrade. Caution Electrical Shock Potentials exist on the Gyro Compass output lines. Assure that the Gyro Compass output is turned OFF when handing and connecting wiring to the ACU Gyro Connector

30 NMEA Output This connector is used to provide GPS NMEA output to a satellite modem or other BDE that required GPS data. Figure 2-21 NMEA Output Connector M&C Control Interface Connection. The monitor and Control port allows external control from a PC using a communication program such as SuperTrack Control Software. The ACU is wired as a DTE device for direct connection to another DTE device such as a PC. Connect RS 232C cable on the M&C port of the ACU and PC serial interface port (COM port). Set the PC to baud, 8 bits, no parity. Figure 2-22 M&C Connector SW1, SW2 The Blockage/TX Mute Control output is driven by Blockage and RF Radiation Hazard functions. These outputs will close whenever the antenna is within the AZ LIMIT zone(s) or in Searching, Targeting. This output is commonly used to drive: Dual Antenna Arbitrator coax switches in VSAT dual antenna configurations. The coax switches select which antenna is feeding signal to the matrix switch. Mute the Transmit output of the Satellite Modem used in TX/RX antenna configurations when the antenna is positioned where people may be harmed by the transmit power emanating from the antenna (RF Radiation Hazard)

31 Figure 2-23 Gyro/SW Strip Console Port Modern satellite modem now provides lock and SNR of its receiving signal. External Modem Lock and analog SNR strength signals from a satellite modem are used as a positive ID that the antenna is on the desired satellite. These inputs also can be used for tracking purpose but the response time from satellite modem is critical for satellite identification and satellite tracking. To enable the external modem input you must enable EXTERNAL MODEM LOCK in the searching or tracking setup menu and NID must be disabled also. Connection The modem lock signal connects to External Modem Lock (pin 2) of console port and modem ground reference from modem connects to GND of Gyro/SW strip. The expected signal from the modem is +5VDC to 0VDC. Low voltage indicates modem lock, high voltage indicates modem unlock. The modem SNR signal connects to External Modem SNR Power (pin 8) of console port. Antenna can use External Modem SNR for searching and tracking satellite according to your setting. If the modem lock signal voltage is 0 15VDC, use external resistor for voltage divider to supply 0 5VDC. GPS data output GPS data can be transmitted via console port (pin 6) to satellite modem also. If your satellite modem is idirect netmodem series, you can connect console port of ACU to console of idirect netmodem directly. The console port of ACU is compatible with idirect console port.

32 RX and TX Cables The TX and RX cables must be routed from antenna radome through the deck and through various ship spaces to the vicinity of ACU. Assure RX cable is connected between RXIN connector of ACU and RX connector of antenna. Another cable should be connected between RXOUT connector of ACU and RX connector of satellite modem. TX cable should be connected between TX connector of satellite modem and TX connector of antenna. Satellite modem supplies DC current for BUC. If BUC consumes lots of current and satellite modem could not supply enough DC current to BUC, you can use internal TX power supply of ACU for BUC. TX cable from antenna should be connected to TXOUT connector of ACU and another cable should be connected between TXIN connector of ACU and TX connector of satellite modem. TX power of ACU is +48VDC and 130W. TXIN connector of ACU is DCblocked. You don t need to turn off TX power of satellite modem. ACU uses RX cable to supply DC (+48VDC) power and transmit control data to antenna. So ACU monitors RX cables to detect the open or short of RX cable continuously. When ACU detects short cable, it shut down the power of RX cable automatically to protect ACU. Assure that the cables have been run through watertight fittings and/or will not permit water entry into the ship when the installation is completed. After cables have been routed and adjusted for correct cable length at each end, seal the deck penetration glands and tie the cables securely in place

33 Figure 2-24 Standard Connection Diagram In standard configuration, check satellite modem TX output power is +24VDC. If satellite modem supply only +48VDC, then you have to replace BUC which has +48VDC input. Default BUC has +24VDC input

34 Figure 2-25 Extended Connection Diagram In extended configuration, TX power of satellite modem is blocked. And ACU TX power module supply +48VDC to the BUC. You have to install BUC that has +48VDC input. Big power BUC (for example, 8W BUC) has option for +48VDC input. Do not use extended connection on default 6W BUC!!! Caution : If ACU supply electric power (+48VDC) to BUC without replacing default BUC (6W, +24VDC input) with new BUC (+48VDC input), it will burns and damage installed BUC!!!

35 2.9 Final Checks Do a visual inspection of your work to assure that everything is ready to proceed and do double check ACU power setting (110V/220V) and all your connections to assure that is safe to energize the equipment

36 3. Basic Information This section provides you with some additional information about the satellites you will be using, basics of your SuperTrack Z12 MKⅡ antenna system and some of the other equipment within your system configuration. 3.1 Satellite Basics The satellites are in orbit at an altitude of 22,754 miles and are positioned directly above the equator. Their orbital velocity matches the Earth s rotational speed, therefore, each appears to remain at a fixed position in the sky (as viewed from your location). Your antenna can be used with any of the satellites in this orbit that have a strong enough receive signal level. Your antenna is capable of being fitted with a Linear or Circular feed assembly. The feed may be designed to operate at C Band frequencies, Ku Band frequencies or be capable of operation in both bands. With the correct feed assembly you will be able to receive the linear or circular signal at the specific frequency range of the desired satellite. Ku-Band Receive Frequency ( GHz) At these frequencies the signal from the satellite travels only in a straight line and is affected by weather changes in the atmosphere. There are several conditions that can cause a temporary loss of satellite signal, even within an area where the signal level is known to be adequate. The most common of these normal temporary losses are blockage and rain fade. They will interrupt services only as long as the cause of the loss persists. Blockage Blockage is loss due to an object in the path of the signal from the satellite to the dish. If an object that is large and dense is positioned in the path of the signal from the satellite, it will prevent sufficient signal from arriving at the dish. The signal can not bend around, or penetrate through, these objects and the reception will be degraded or completely interrupted. The dish is actively driven to remain pointed at the satellite (toward the equator) so, as the ship turns a mast or raised structure of your ship may become positioned between the satellite and the dish. Blockage may also be caused by anything standing near the radome, tall mountains, buildings, bridges, cranes or other larger ships near your ship. Moving or rotating the ship to position the antenna where it has an unobstructed view to the desired satellite, it will restore the antennas ability to receive the satellite signal. Rain Fade Atmospheric conditions that may cause sufficient loss of signal level include rain, snow, heavy fog and some solar activities (sun spot and flare activity). The most common of these is referred to as

37 rain fade. Rain drops in the atmosphere reduce the signal from the satellite. The heavier the rain, the higher the amount of signal loss. When the amount of loss is high enough, the antenna will not be able to stay locked onto the satellite signal. When the amount of rain has decreased sufficiently, the antenna will reacquire the satellite signal. In a strong signal area, rain fall of about four inches per hour will cause complete loss of signal. In weaker signal areas the effects would be more pronounced. Signal Level The level of the receive signal is dependant upon how powerful the transmission is and how wide the signal beam is coverage area is. Focusing the signal into a narrower beam concentrates its energy over a smaller geographic area, thereby increasing the signal level throughout that area of coverage. This makes it possible for you to use a smaller antenna size to receive that satellite signal. The antenna system must be geographically located in an area where the signal level from the satellite meets (or exceeds) the minimum satellite signal level required for your size of antenna (refer to the Specifications section of this manual) to provide suitable reception. This limits the number of satellites that can be used and the geographic areas where the ship can travel where the signal level is expected to be strong enough to continue providing uninterrupted reception. When traveling outside this minimum signal coverage area, it is normal for the system to experience an interruption in its ability to provide the desired satellite services until entering (or re entering) an area of adequate signal level. Satellite Footprints The focused beam(s) from the satellites are normally aimed at the major land masses where there are large population centers. Footprint charts graphically display the signal level expected to be received in different geographic locations within the area of coverage. The signal will always be strongest in the center of the coverage area and weaker out toward the outer edges of the pattern. The Drawing section of this manual contains footprint charts of satellites that are expected to provide adequate signal level for your size antenna. The coverage areas are intended to be a guide to reception, however, the actual coverage area and signal level and vary. Also the signal strength is affected by weather. Linear Satellite Polarization Satellites may transmit their signals in one of two different polarization modes, linear or circular. The feed installed on your antenna is designed to operate with horizontal and vertical linear polarized satellite transmissions, thereby requiring periodic adjustment of polarization. Polarization adjustment is required to optimize the alignment of the LNB to match the angle of the signal from the satellite

38 Figure 3-1 Satellite Signal Polarization When you are on the same longitude as the satellite, its horizontal and vertical signals will be purely aligned to your horizon. When the satellite is east or west of your longitude, the satellite signals will appear to be rotated clockwise or counter clockwise from pure horizontal and vertical. Both horizontal and vertical signals from a satellite will appear to be rotated the same amount and are always perpendicular to each other. The amount of rotation is dependent on how far east or west the satellite is from you and how close you are to the Equator. 3.2 Antenna Basics The following information is provided to explain some of the basic functions of the antenna: Unlimited Azimuth Azimuth rotation of the antenna is unlimited (no mechanical stops). Azimuth drive, provided by the azimuth motor, is required during stabilization, searching and tracking operations of the antenna. When the boat turns, azimuth is driven in the opposite direction to remain pointed at the satellite. The actual azimuth pointing angle to the satellite is determined by your latitude & longitude and the longitude of the satellite. It is important to know that the antenna should be pointed (generally) toward the equator. The azimuth angle to the satellite would be 180 degrees true (relative to true north) if the satellite is at the same longitude that you are on. If the satellite is east, or west, of your longitude the azimuth will be less than, or greater than 180 degrees respectively. When checking for blockage you can visually look over the antenna radome toward the equator to see if any objects are in that sighted area. If you are not able to find any satellites it may also be useful to remove the radome top to see if the dish is aimed the correct direction (towards the equator)

39 Elevation In normal operation the elevation of the antenna will be between 00.0 (horizon) and 90.0 (zenith). The antenna can physically be rotated in elevation below horizon and beyond zenith to allow for ship motion. Elevation drive, provided by the elevation motor, is required during stabilization, searching and tracking operations of the antenna. The actual elevation pointing angle to the satellite is determined by your latitude & longitude and the longitude of the satellite. In general terms the elevation angle will be low when you are at high latitude and will increase as you get closer to the equator. Refer to figure 3 1. Additionally, from any given latitude, the elevation will be highest when the satellite is at the same longitude that you are on. If the satellite is east, or west, of your longitude the elevation angle will be lower. Feed Assembly The scalar section of the feed is fitted with a polarization motor and a potentiometer for position feedback required for linear signal operation. The appropriate LNA, LNB or LNC must be installed on the feed to receive the frequencies of the desired satellite. ACU automatically adjusts the feed by remotely controlling the 24 volt DC motor, using the potentiometer feedback for linear polarization position (Auto Polarization mode). Antenna Polarization You have a linear polarization feed installed, the system should have been adjusted properly and set up to operate in Auto Polarization mode. The ACU will then automatically adjust the polarization of the feed, as necessary, while the ship travels in Latitude and Longitude. Stabilization The SuperTrack Z12 MKⅡ antennas are stabilized in all three axes of motion. Stabilization is the process of de coupling the ships motion from the antenna. This allows the antenna to remain pointed at a point in space while the boat turns, rolls or pitches under it. To accomplish this, the Pedestal Control Unit (PCU) on the antenna pedestal assembly senses the motion and applies drive to the appropriate motor(s) in opposition to the sensed motion. Azimuth (AZ), Elevation (EL) and Cross Level (left right tilt) are actively stabilized automatically by the PCU as part of its normal operation. Search Pattern Whenever the desired satellite signal is lost (such as when the antenna is blocked) the Antenna Control Unit will automatically initiated a Search to re acquire the desired signal

40 Search is conducted in a two axis pattern consisting of alternate movements in azimuth and elevation. The size and direction of the movements are increased and reversed every other time resulting in an expanding square pattern. When the antenna is able to re acquire the desired signal the ACU will automatically stop searching and begin tracking the signal to optimize the pointing of the antenna to get the highest signal level from the satellite. Network ID Satellite Identification The Satellite Identification Circuit located in the Pedestal Control Unit (PCU) is used to acquire, identify and track a specific satellite by its unique hexadecimal ID code. When properly setup, the settings for the satellite are saved to expedite future acquisition of the desired satellite. When searching for the selected satellite this circuit compares the present satellite ID to the targeted satellite ID code. If the ID code does not match the antenna will continue searching until the correct satellite is found. The system must have adequate satellite signal level, AND the matching NID, to stop searching (and begin tracking the desired satellite). Tracking Your Pedestal Control Unit actively optimizes the pointing of the dish for maximum signal reception. This process is called tracking and is accomplished by continuously making small movements of the dish while monitoring the level of the received signal. Evaluation of this information is used to continuously move the stabilization point toward peak satellite signal reception. These minor pointing corrections keep the signal level peaked as part of normal operation

41 3.3 Components of the System Configuration Figure 3-2 SuperTrack Z12 MKⅡ TX/RX System Simplified Block Diagram The following text provides a basic functional overview of the system components and component interconnection as referred to in the simplified block diagram for your SuperTrack Z12 MKⅡ antenna. Also, refer to the appropriate page of the System Block Diagram which depicts your system configuration. Antenna ADE Assembly The Above Decks Equipment consists of an Antenna Pedestal inside a Radome assembly. The pedestal consists of a satellite antenna dish & feed with a linear, or a circular Low Noise Block converter (LNB) with polarization motor mounted on a stabilized antenna pedestal. The radome provides an environmental enclosure for the antenna pedestal assembly inside it. This keeps wind, water condensation and salt water spray off the antenna pedestal assembly. This prevents damage and corrosion that would shorten the expected life span of the equipment. Two coaxial cables are connected from the antenna radome assembly to the below decks equipment. RX cable transmits Data, DC power (+48V DC) and RX signal. TX cable transmits on TX signal

42 Figure 3-3 SuperTrack Z12 MKⅡ Above Decks Equipment Antenna Control Unit The Antenna Control Unit allows the operator to control and monitor the antenna pedestal with dedicated function buttons, LED s and a 2 line display. The ACU is normally mounted in a standard 19 equipment rack. The ACU should be mounted in the front of the equipment rack where it is easily accessible. It is recommended that the antenna control panel be mounted near satellite modem locations. The Antenna Control Unit is connected to the antenna, ships Gyro Compass and satellite modem

43 Figure 3-4 KA-150 Antenna Control Unit The Antenna Control Unit (ACU) communicates via a Bluetooth RF serial data link with the Pedestal Control Unit (PCU) located on the antenna. Bluetooth module needs identification setting. When antenna is shipped, Bluetooth modules of PCU and ACU are configured as same id at factory. If ACU is replaced with new one, the id of PCU Bluetooth module should be set to ACU Bluetooth module. This control signal is sent via the RX cable along with the DC voltage for the antenna power. The Pedestal Control Unit stabilizes the antenna against the shipʹs roll, pitch, and turning motions. The ACU is the operator interface to the PCU and provides the user with a choice of positioning commands to point the antenna, search commands to find the satellite signal and tracking functions to maintain optimum pointing. Power Supply The Antenna Control Unit (ACU) has two power modules. One is for Antenna itself and another is for BUC. If you modem doesn t not supply enough current for BUC, we strongly recommend to use TX power module (+48VDC 130W). Both power modules have universal AC input. It means that if your source of AC Voltage is between 85VAC and 250VAC, you don t need to select slide switch of power inside or outside ACU. The maximum output of power module is 130W

44 4. System Operation 4.1 System Power On Turn the Power switch on the front panel of the Antenna Control Unit (ACU) ON. This will energize the antenna pedestal and the associated RF equipment. 4.2 Antenna Initialization A functional operation check can be made on the antenna stabilization system by observing its behavior during the 4 phases of initialization. When ACU is powered ON, the PCU will initialize the stabilized portion of the mass to be level with the horizon and at a prescribed Azimuth and Elevation angles. The antenna will go through the specific sequence of steps (listed below) to initialize the antenna. These phases initialize the level cage, elevation, cross level and azimuth to predetermined starting positions. Initialization is completed in the following phases, each phase must complete properly for the antenna to operate properly (post initialization). 1 Level Cage is driven CCW, issuing extra steps to assure that the cage is all the way to the mechanical stop. Then the Level cage will be driven exactly 45.0 degrees CW. 2 Elevation axis activates Input from the LV axis of the tilt sensor is used to drive the Elevation of the equipment frame to bring the tilt sensor LV axis to level (This results in the dish is being at an elevation angle of 45.0 degrees). 3 Cross Level axis activates Input from the CL axis of the tilt sensor is used to drive Cross Level of the equipment frame to bring the cross level axis of the tilt sensor to level (This results in the tilt of the Cross Level Beam is being level). 4 Azimuth axis activates Antenna drives in azimuth until the Home Flag signal is produced. This signal is produced by a Hall Effect sensor in close proximity to a Magnet. This completes the phases of initialization. At this time the antenna elevation should 45.0 degrees and Relative azimuth should be at home flag (home switch engaged on the home flag cam). If any of theses steps fail, or the Antenna Control Unit reports an error message as described in troubleshooting section of this manual. Refer to the troubleshooting section of this manual

45 4.3 Antenna Stabilization After initialization has completed, real time stabilization of the antenna is an automatic function of the PCU to compensate ship motion. Yaw heave serge sway Roll Pitch Figure 4-1 Ship Motion

46 4.4 Stabilized Pedestal Assembly Operation Operation of the stabilized antenna Pedestal Control Unit (PCU) is accomplished remotely by the Antenna Control Unit (ACU). Refer to the Operation Menu for more specific operation details. There are no other operating instructions applicable to the pedestal assembly by itself. 4.5 Tracking Operation Tracking optimizes the antenna pointing, in very fine step increments, to maximize the level of the satellite signal being received. The mode of tracking used in this antenna is a variation of Conical Scanning called DishScan. DishScan continuously drives the antenna in a very small circular pattern at 60 RPM. The ACU evaluates the received signal throughout each rotation to determine where the strongest signal level is (Up, Right, Down or Left) and issues the appropriate Azimuth and/or Elevation steps to the antenna, as needed. 4.6 Antenna Polarization Operation Linear feeds are equipped with a polarization motor and potentiometer feedback and are controlled from the Antenna Control Unit. Auto Polarization mode is the default polarization mode of operation from the ACU. Polarization may be operated manually from the ACU for diagnostic or alignment purposes. 4.7 RF Equipment The RF Equipment is not operated or controlled by the antenna pedestal or Antenna Control Unit. Refer to the vendor supplied manuals for the RF Equipment provided with your system. 4.8 FCC TX Mute Function FCC TX Mute function provides transmit inhibit, or mute, signal to the Satellite Modem to disable transmit whenever the antenna is blocked, searching or is mis pointed 0.5 degrees from peak satellite position. This function is provided by software in the ACU & PCU, hardware wiring connection between the ACU and the Satellite Modem and proper setup of the ACU. After the function has been installed and setup correctly the FCC TX Mute function operation is automatic, therefore, requires no operator intervention. 4.9 Radome Assembly Operation When operating the system it is necessary that the radome access hatch (and/or side door) be closed and secured in place at all times. This prevents rain, salt water and wind from entering the radome. Water and excessive condensation promote rust & corrosion of the antenna pedestal. Wind gusts

47 will disturb the antenna pointing. There are no other operating instructions applicable to the radome assembly by itself

48 5. Installation Setup Below are installation steps to guide you in setting up antenna first time. Assure that the Antenna Pedestal has been properly installed. Press key and hold for 2 3 seconds to go to Installation Menu. In installation menu, we are going to set up all parameters those are needed for installation. Bluetooth Initialize* Ship Heading Offset ENTER Antenna Searching range Polarity Calibration* F/ESC Block Zone Gyro Compass Type Compass Operation Mode GPS Output Format Tilt Sensor Offset* TX Power On/Off Save Parameter Installation menu has 10 sub menus and they should be configured very carefully. * This menus are used for repair purpose only

49 5.1 Brief Procedure for Installation If you finish installation and wiring antenna, left thing is as follows. 1) First check Gyro compass is properly connected. If so, configure gyro type in installation menu. NMEA or Syncro or Step by Step etc. Ask ship crew who are in charge of Gyro to change Gyro angle slightly and check and compare the heading value with Gyro compass value. If those values are same, your installation is half done. 2) Go to SHIP HDNG OFFSET of installation menu. Estimate the adjustment offset angle between antenna heading and ship heading. Configure offset value and save it. 3) Go to S&T REF DETAILS and DVB Tuner Menu. Configure best searching and tracking method for your satellite. If possible, DVB carrier Lock for searching and DVB AGC for tracking make best performance for antenna. 4) Go to Sat Finding Method. Find your satellite by auto searching method. Antenna will search your target satellite in +/ 10 degree range. If antenna line up error is less than 10 degree, auto searching will find your target satellite. 5) Perform SAT CAL (a well known program) to calculate the theoretical azimuth angle. Determine the difference between theoretical angle and ACU angle to find correct offset value of antenna heading offset. This value should be added to current SHIP HDNG OFFSET. 6) Now installation is finished. If antenna can not track your target satellite, choose another searching and tracking method. If you are not familiar with your satellite, it is good idea to ask expert some help. If you upload SHIP HDNG OFFSET, antenna should point to ship s heading angle. You can easily see and check through radome hatch door. If not, make adjustment of offset value

50 5.2 Bluetooth Initialize ADE and BDE are communicating by Bluetooth modem over RX cable. When Bluetooth module is replaced, new Bluetooth module should be recognized by current Bluetooth module. This menu is not necessary for installation setup.

ACU is checking and scanning Bluetooth module of PCU. Press ENTER to confirm PCU Bluetooth address. If address does not show up, check Bluetooth module of PCU. ACU is trying to communicate with PCU by scanned Bluetooth addresses of both sides. Bluetooth module initialization is over. But you have to turn off and on ACU to store the scanned addresses. Some module does not require this option but it is good to recycle power to make it sure

51 5.3 Ship Heading Offset The mounting base of antenna can be installed in any orientation although physically matching the antenna heading to ship heading is strongly recommended. Antenna heading reference line can be observed on radome base called BOW mark. When there is an angle deviation between ship heading and antenna heading, the difference must be determined in order for antenna to point toward a correct azimuth angle. In this menu, installer can set offset value between antenna and ship headings. Upon Ship Heading Offset is properly configured and uploaded, antenna should point to ship heading. Small difference is allowable but it is highly recommended to match the line up as precise as possible. Caution : Gyro Compass must be connected and properly configured before antenna line adjustment for proper validation.

52 5.4 Searching Parameter Setting A search pattern will automatically be initiated when AGC falls the current threshold setting or after antenna initialization when ACU power turned on. The search, its pattern dimensions and timing are determined by searching parameters ELE RANGE, AZI RANGE, STEP and SCH DELAY. Search is conducted in a two axis pattern consisting of alternate movements in azimuth and elevation forming expanding square. The size and direction of the movements are increased and reversed every other time resulting in an increasing spiral pattern as shown below.

53 5.5 Polarity Zero Calibration When polarity gear is replaced by some reason, you should initialize correct zero position. During normal operation, any changes in this parameter other than factory set value may cause faulty operation of automatic polarity adjustment. When polarity gear is installed in factory during manufacturing process or replaced for repair, polarity gear must be initialized to zero by configure this parameter. When OMT plate is in parallel to cross bar, that is in parallel to earth surface also, the zero occurs and zeroing needs to be entered. Display ZERO CALIBRATION CR ANGLE:0000 MODE:MANUAL >SET ANGLE:0000 ZERO SETTING ENTER TO CALIBRATE Meaning Press UP or Down arrow to select the POLARITY ZERO CALIBRATION menu.

You have to set current position as zero degree. Press Enter to upload

54 5.6 Block Area Setting The signal from a satellite to the antenna is a line of sight so that ship structures can block the signal in a certain azimuth angle. If antenna is transmitting during this structural blockage, it may cause a harmful interference or radiation. Installer can store up to three blocking area (ZONE) into ACU, with which ACU can determine if the antenna is under block area or not and it sends a contact closure (CC) signal via SW1 and SW2 of Gyro strip. It is NC for nonblocking area. This switch output can be used for operator to control transmission on or off. Caution : Block angle is relative angle from ship heading. Figure 5-2 Ship Block Zones

Press ENTER key to go next menu. When the block area parameters are set to activate ZONE, several things happen when antenna is within one of the zones: 1. Tracking continues as long as the antenna can track satellite according to your tracking method. When antenna lost satellite signal the antenna will wait Search Delay parameter amount of time and then re target the satellite you targeted last. Timeout and re target will continue until the satellite is reacquired and tracking can resume. 2. BLOCK will be displayed in the TOP window wherever the antenna is inside one of the zones. 3. A contact closure is provided on the SW1 and SW2 terminal of Gyro Strip. This switch output provides a Blocked, RF Radiation Hazard or FCC TX Mute output. When the antenna exits the zone it will be on satellite, tracking and the SW1 and SW2 contact closure will open. The lower and upper limits are user programmable and are stored in ACU. START RELATIVE ANGLE is the lower relative azimuth angle (this is the counter clockwise of the two points, even if it is numerically larger). STOP RELATIVE ANGLE is the upper relative azimuth angle for pattern mapping of each zone. Contact closure is a relay contact with current capacity of 0.3A at 125VAC. The contact closure could be used to light a remote light or sound a buzzer to alert someone that the antenna is blocked, and signal is lost. In a dual antenna installation, this output is used to control dual antenna arbitrator panel of

56 coax switch to switch the source inputs to the matrix switch. When used as simple RF Radiation Hazard, this output could be used to suppress RF transmissions while the antenna is pointed where people would be harmed by the transmitted microwave RF power output. The SW1 and SW2 output would be interfaced to the satellite modem to disable the TX output signal from the satellite modem whenever the antenna is within the RF Radiation Hazard zone. When used for FCC TX Mute, this output could be used to suppress RF transmissions whenever the antenna is mis pointed 0.5 degrees or more, is blocked, initializing, searching and targeting. Programming instructions: Determine the Relative AZ positions where blockage, or RF Radiation Hazard, exits. This may be done by monitoring the received signal level and the REL display readings while the ship turns or by graphing the expected blockage pattern. Elevation of the antenna in normal use also must be taken into consideration. A mast or other structure may cause blockage at low elevation angles, but may not cause blockage when the antenna is at higher elevation angles. Up to three zones may be mapped. Only zones which are needed should be mapped (in Start and Stop AZ angle pairs). If you set START and STOP angle as 0, corresponding zone is disabled

57 5.7 ACU Gyro Compass Type There are multiple types of Gyro compass for vessels, each of which requires unique selection. KNS antenna supports the following Gyro compass output types. NMEA 0183 SYNC 360:1 SYNC 180:1 SYNC 90:1 SYNC 36:1 SYNC 1:1 STEP BY STEP 360:1 STEP BY STEP 180:1 STEP BY STEP 90:1 SYNC or STEP Gyro also requires a Direction Setting that has two choices, Normal or Reverse. When direction setting is Normal, a change of voltage is proportional to the change of ship heading in a defined ratio such as 1:1, 360:1 etc. When direction setting is Reverse, a change of heading is reversely proportional to the change of ship heading in a defined ratio. Refer to Gyro compass section for more details.

If ship heading display does not follow ships movement, determine the type of gyro compass that is used on the ship, assure that the Gyro parameter is set correctly

58 5.8 PCU COMPASS MODE The ships gyro compass input to the ACU may be accurate and stable in static conditions and yet may NOT be accurate or stable in some underway dynamic conditions. If there is no gyro compass or if the input is corrupt, not stable or not consistently accurate the tracking errors will become large enough to cause the antenna to be mis pointed off satellite. There are 3 compass operation modes for antenna, Normal, Failed and Internal Magnetic Compass mode. In Normal mode, antenna uses ship gyro compass for stabilization control. In Failed mode, antenna does not use any gyro output. When operating in Failed mode (so called reference mode) the changes in ships gyro reading will not directly affect the antenna control routine. The antenna system will stabilize the antenna based entirely on embedded 3 axis gyro sensors, 2 axis tilt sensors and the tracking information from DishScan. This mode is useful when ship gyro compass is out of service or antenna is operated in no gyro compass environment like a truck. When you want to run antenna on truck, you have to set PCU COMPASS MODE as Failed because you could not get any gyro compass interface from truck equipments. But in Failed mode, if antenna lost satellite long time by blockage or some reason, the ship heading information must be manually entered to acquire satellite again. When your ships gyro compass is GPS Satellite compass, you should run antenna in compass Failed mode. GPS Satellite compass output is too slow to use for antenna tracking control.

Press UP or Down arrow to select Gyro operation mode. When you find correct mode, press Enter key to upload. When your antenna runs in Compass Failed Mode, it is good to turn off searching function. If you turn off searching function, antenna does not enter searching mode to find satellite even in blockage. When antenna exist blockage again, it can reacquire satellite immediately

60 5.10 TILT SENSOR OFFSET Tilt sensor has two axis, level and cross. When tilt sensor board is replaced, both axes must be leveled by adjusting the offset of each tilt axis. When antenna is stable, put small leveler on the sensor box. If bubble is not on the center of leveler, there must be offset error. Carefully adjust each axis offset parameter to compensate existing offset error.

61 5.11 TX 48VDC POWER ON/OFF ACU has a built in 48VDC power supply (130W) for BUC. Most satellite modem can supply 24/48VDC power up to 4 6W BUC. When user needs 8W BUC, modem can not supply enough power so that external DC power supply is commonly used with satellite modem. With builtin 130W DC power supply dedicated to TX BUC, ACU can provide enough power to BUC. If BUC is installed by customer, please be aware the voltage is 48V. Default is 48VDC. However, it is possible to use 24VDC version as option.

62 6. To operate your system Normal operation begins by turn on the POWER switch and waiting for the antenna to automatically acquire and track the desired satellite signal. After the system has been properly installed and set up, the initialization should take approximately 1 minute. 6.1 Quick Start Operation If your system has been set up correctly, is using factory default parameters and ship has not moved since the system used last., Quick start operation of the system from a cold start involves the following steps. 1. Turn on the AC power switches for the Antenna Control Unit (ACU) and other Below Decks Equipment. 2. Heading in most cases will be and you will have to enter the initial value of the ships current heading according to your gyro type. Entry of ships heading is not required when your system is connected to a 1:1 Synchro or NMEA 0183 Gyro Compass Output. For all other Gyro Compass input types the initial heading value must be set whenever the ACU power is turned on. And if entry of ships heading is required, ACU automatically displays Heading Entry Mode. Then input initial heading value to SET using numeric key pad. Press ENTER to save the value.

63 3. If you are targeting the SAME satellite longitude as was used last, the antenna starts to search your satellite. If you are targeting a different satellite you will need to change the tracking satellite settings and then target the desired satellite. A. If no signal is found: The Searching message will be displayed continuously. The antenna will automatically expand searching range in spiral SEARCH pattern. The search movement will stop when the antenna receives a strong enough signal. Tracking will take over (Tracking message will be displayed) and automatically peak the antenna position for highest receive signal level from the satellite which has been acquired. B. If a satellite signal is found: The received signal level (AGC) will rise rapidly to a maximum value.

65 6.4 Basic Description of ACU messages The basic descriptions of the ACU messages are: INIT: Antenna is initializing. Initializing of the antenna will take approximately two minutes. After initialization, antenna calculates the azimuth & elevation position of the desired satellite and moves to the calculated position. SCH1: Antenna is searching for a satellite signal whose parameters are matched with the saved value. When a satellite signal is found, the TRACK message will be displayed. If an adequate satellite signal is not found during the search, the SCH1 message will be displayed continuously as the antenna re targets to the desired satellite. Until an adequate satellite signal is found, the antenna expands the Searching range. SCH2: When satellite searching method is DVB carrier lock, antenna enters second searching after first searching because that current robe may be side robe not main robe. If your satellite signal is strong, antenna can lock satellite carrier even in side robe. Second searching tries to find main robe signal (stronger signal than current signal of same satellite). If antenna finds stronger signal, antenna considers it as main robe and move to new signal. Otherwise, previous robe is considered as main robe. TRACK: Antenna is tracking a satellite signal whose parameters are matched with the saved value. The antenna is actively issuing small azimuth & elevation position adjustments to optimize the signal level. When the antenna lost the desired satellite signal, the antenna will automatically start a search to reacquire a signal that is matched with saved parameters. BLOCK: Antenna is in blockage region whose parameters are set by START REL ANGLE and STOP REL ANGLE where radiation hazards or known blockage regions up to 3 zones. When the ship turns and the antenna comes out of signal blockage, tracking and auto searching is initiated automatically. * : When TX power supply is activated, * is displayed. When satellite modem does not supply enough power to BUC, activate TX power supply in installation SETUP menu. TRACK LED: ON indicates that ACU is tracking a satellite signal whose AGC value is greater than threshold value or DVB carrier is matched. Blinking indicates that ACU is searching satellite. GPS LED: On indicates that GPS data is valid. Blinking indicates GPS data is invalid. OFF indicates GPS antenna is out of service

66 ERROR LED: ON indicates that one, or more, discrete system errors have occurred. Refer to Error Code information to determine which error(s) have occurred. OFF indicates that no errors have occurred or error was checked by pressing MENU

67 6.5 Boot up Display When turn on the ACU, the ACU will attempt to communicate with Pedestal Control Unit. And ACU sequences the following steps: After completing self diagnosis, ACU shows system version number and go to the normal operation mode. NOTE: Acquisition time may be longer when the Antenna Unit is turned on first time, this will happen on an installation or after resetting memory. The signal acquisition may take up to ten minutes this will allow for the GPS to acquire the satellite information necessary to acquire latitude and longitude information of ship location. If you do not have a signal after three minutes normally, be sure there are no obstacles preventing signal acquisition. (Other ship, radar or other structures can block the signal.) Move to an open area so your system can see the satellite signal. Signal interruption occurs while traveling when the line of site to the satellite is blocked. This corrects itself when blockage is cleared

68 7. Operation Setup 7.1 Function Key Mapping Installation setup is accomplished by the installer or operator using SETUP Mode to configure the system parameters. Optionally the computer interface may be used to setup the system. The installation setup consists of operations that would normally only be performed during the installation.

71 7.4 Satellite Searching Method (Key 3) There are five searching references, which are RSSD Threshold, DVB AGC Threshold, Ext. AGC Threshold, DVB carrier lock bit, and Ext. device lock bit. There are three tracking references, which are RSSD level, DVB tuner AGC level, and DVB tuner C/N ratio. Operator can use any reference out of five searching references and any reference out of three tracking references. Table 7-2 Searching Reference Searching reference RSSD Threshold DVB AGC Threshold DVB carrier lock External Lock Bit Description Searching the satellite using RSSD threshold level. RSSD measures the power spectrum of about 50Khz at its tuned center frequency and represents its strength as RSSD level (higher is stronger). The antenna believes that it points toward the target satellite whenever RSSD level is above the threshold. Hence, a threshold level value should be carefully selected for the successful searching process. Searching the satellite using DVB tuner AGC threshold level. DVB tuner measures the power spectrum of about 2 MHz at its tuned center frequency and represents its strength as AGC level (higher is stronger). The antenna believes that it points toward the target satellite whenever DVB AGC level is above the threshold. Hence, a threshold level value should be carefully selected for the successful searching process. Searching the satellite using DVB carrier lock. If the antenna points the target satellite and DVB tuner has a correct carrier parameter, DVB demodulator locks on the carrier and set the lock bit on, which means antenna most likely points toward the correct satellite. This requires to configure DVB tuner with correct carrier parameters such as frequency, symbol rate, FEC. (DVB S2 is not supported yet) Searching the satellite using a logical voltage status of external contact closure (CC). When the voltage level of CC is logical high, the lock bit is considered on. (Currently only logical high is supported). Like in built DVB tuner, some external demodulators are capable of generating a lock signal when carrier is locked. This information can be used for searching in the same manner of DVB carrier lock. However, the response time of external device between detecting lock and setting lock on must be fast enough to KNS searching process, otherwise, KNS antenna won t be able to use this option. To keep response time a minimum, it is necessary to use a minimum value of acquisition range and PLL based LNB. Note: one fall back is when antenna is on tracking process, if the lock bit is off (logically unlocked) for example by disconnecting the CC, then the antenna will start searching process. This will also apply to External AGC Threshold if used for searching

72 External AGC Threshold Searching the satellite using the threshold level of AGC from external device. Like in built DVB tuner, some external demodulators are capable of generating AGC level of RX carrier strength in analog voltage level. This information can be used for searching in a same manner of DVB AGC Threshold. However, if the response time between detecting the change of carrier level and generating AGC level is slow, it can not be used. To keep response time a minimum, it is necessary to use a minimum value of acquisition range and PLL based LNB. Note: one fall back is when antenna is on tracking process, if the AGC level is below threshold (logically unlocked) for example by disconnecting the CC, then the antenna will start searching process. This will also apply to External Lock Bit.

74 7.5 Polarity (Key 4) Standard Auto Polarity needs to be selected for satellite with standard polarity. However, there are some satellites using offset added to its standard polarity, which can not be calculated by standard polarity calculation program. For non standard polarity, antenna must be peaked in manual mode and then uploaded as NON STD AUTO POL. Fortunately, most satellites use standard polarity but there are some satellites using nonstandard way of linear polarity. If satellite uses standard polarity, what operator have to do is to select STD AUTO POL. However, with non standard polarity, operator must follow a special procedure below. KNS antenna uses AUTO POL calculation program with TRIM ANGLE (offset) to compensate this difference in polarity. 1) Go to S&T Ref. (key 5) and make sure SATELLITE RX POLARITY is correct. 2) Go to Polarity and peak the polarity using MANUAL and JOG. 3) Then go to AUTO and select NON STD AUTO POL. Display Meaning Press the Enter key to enter POLARITY Setting. CONFIG: POLARITY(0025DEG) AGC:02980 MODE>[JOG] It shows current polarity angles and AGC value.

76 7.6 Searching & Tracking Reference (Key 5) There are three different ways of finding satellite methods (manual pointing, manual searching, auto searching and reference searching). Each method requires searching and tracking references for searching and tracking processes respectively. Manual Pointing: In this method, user needs to manually enter EL and AZ, toward which antenna points. Antenna will never go searching but tracking only when there exists the selected tracking reference. This option is different from Searching off (Key +/ ). Manual pointing points per entered EL and AZ while searching off points per Sat Cal using GPS provided location and entered satellite orbit location. Manual Searching: In this method, user needs to manually enter EL and AZ, from which antenna starts KNS proprietary searching pattern to find the target satellite. There are multiple searching references, which can be divided into two types, threshold level and lock bit. 1) Threshold searching reference includes Received Signal Strength Detector (RSSD) and DVB Automatic Gain Control (AGC). In these searching references, antenna performs searching pattern until the level measured by RSSD tuner or DVB tuner exceeds the pre configured threshold level. Basically when the level measured by RSSD or DVB tuner is above the pre configured threshold level, the antenna believes it is searching the right satellite and completes searching pattern and shift from searching to tracking: tracking reference can be selected separately from searching reference. One fall back of these reference is that antenna possibly points to a wrong satellite if it has a carrier with higher energy level and using the same frequency of the correct carrier on a target satellite: this undesired situation can be avoided by shifting the center frequency of tuners. The pass band of RSSD is 100Khz while DVB tuner has approximately 2 MHz of passing band. 2) Lock bit references consist of DVB carrier lock and external device (demodulator) lock; currently, only idirect modem is supported. In these references, antenna performs searching method until the lock bit is on, which means DVB tuner has carrier lock or external device (demodulator) has a carrier lock. In most case, these references guarantees antenna to search the target satellite because most likely carrier parameters such as frequency, info rate, FEC, modulation type, etc will be unique. So if there is a desired carrier lock, then the antenna is mostlikely pointing to the target satellite; the possibility of adjacent satellite having an identical carrier would be very low; when there is a very rare migration of TVRO station from one satellite to adjacent satellite, the TV operator can radiate an identical carrier onto both satellites. When external device (demodulator) is used, it is very important to keep a lock time as low as possible. KNS antenna uses DSP process, which requires fast response. When antenna is on a target satellite, external device receives the correct carrier and tries to have demodulator locked on it. In order to accelerate this process, it is necessary to use a PLL based LNB and a lowest possible acquisition range (30Khz or less) in demodulator setting (ibuilder tbd); acquisition range needs to be increased only when there is an instable reference of frequency, which is common in RX only satellite communication such as DRO LNB. However TX/RX Satellite communication must use PLL based frequency reference. Most case of using long acquisition range in TX/RX satellite communication can be considered as a wrong configuration but the difference in carrier lock time

77 of 10ms Vs. 1 sec may not be any critical issue to most application except for KNS antenna when external lock bit is selected. Also, the minimum acquisition range is more required when the size of carrier is small. For example, when the carrier size of 500Khz, the acquisition range of 500Khz will take a very long time to get a lock where KNS antenna can not use this option. 30Khz of acquisition is much better position. When the carrier size is 5Mhz, 500Khz or 30KHz of acquisition range may not make a difference although still lowest possible acquisition range is recommended. Note: with external device lock selected, if the device is removed or cable is disconnected so that lock bit is off even if the antenna tracking on a target satellite, the antenna will go searching, which may be a undesired situation. In order to avoid this, user can change the searching reference to others such as RSSD with properly configured threshold value. Auto Searching: In this method, the system runs a built in satellite calculation program using preconfigured information such as satellite orbit (under satellite information setting menu) and longitude and latitude (from GPS, or manually entered in case of GPS failure). The program calculates EL and AZ, from which antenna starts KNS proprietary searching pattern to find the target satellite. The rest is the same as manual searching. Reference Searching: This searching method is very unique searching function of KNS antenna. If your target satellite has the adjacent satellite which has the same RF characteristics of target satellite. In this case, it is impossible to acquire the target satellite correctly by auto searching. But KNS antenna provides reference searching method to solve this problem. Determine unique satellite that is easy to find as reference satellite and choose reference searching method for searching. Then antenna will find reference satellite first and calculate the relative distance from reference to target satellite. When antenna finishes calculation, it jumps to your target satellite directly. This searching method is very unique and powerful tool when you have adjacent satellite problem

82 7.10 Searching On/Off (Key +/-) Searching off is a special function to prevent antenna from going into searching process when searching condition occurs such tracking failure. Antenna simply points toward the direction calculated by satellite calculation. This searching method is very useful when there are frequent blockages of short duration; in other searching method, any blockage causes antenna to go searching where searching pattern is initiated. In this method, after a short blockage, the antenna recovers the satellite immediately and goes into tracking, which will re optimize antenna pointing. A long duration of blockage may cause pointing drift by antenna sensors drifts so that the pointing becomes inaccurate, which may cause the antenna lose the target satellite.

84 7.12 Satellite Index (Key ) This menu is only available on top menu. In this menu, operators can move to other satellite by simple selection of satellite index. Upon selecting new satellite index, the antenna starts searching and tracking processes according to parameters based on the selected satellite. If the new satellite index is a different satellite with different parameters, then the antenna will search the different satellite. For example, let s say there are two fully configured records of satellite index, 01:SMX5 (Satmex 5) and 02:NSS7 (NSS7). If the antenna is using STR 01:SMX5 and operator select 02:NSS7, then the antenna will search and track on NSS 7 satellite according to stored parameters of 02:NSS7. One tip for this menu is that operators can configure multiple records of Searching and Tracking Reference (STR) for one satellite or multiple satellites. You can save satellite parameters up to 80.

These equipments are covered by the applicable warranties of the respective manufacturers. Factory refurbished components used to replace systems parts under this warranty are covered by this same warranty as the original equipment for the balance of the original warranty term, or ninety (90) days from the date of replacement, whichever occurs last. Original Installation of the SuperTrack Z12 MKⅡ Series must be accomplished by or under the supervision of an authorized KNS dealer for the KNS Limited Warranty to be valid and in force. Should technical assistance be required to repair your system, the first contact should be to the agent/dealer you purchased the equipment from. Please refer to the complete warranty information included with your system. 9.2 Maintenance Ensure that all of the normal operating settings (LAT, LON, HDG, SAT and al of the Tracking Receiver settings) are set correctly. Check ACU Parameters Assure that the parameters are set correctly (you may wish to record them)

89 Latitude/Longitude Auto-Update Check Assure that the Latitude & Longitude are updated according to your geographical location. Heading Following Assure that HDG angle of ACU is following to ship gyro angle. Gyro compass output response time should be real time. Slow response will make antenna unstable when ship turns fast. Azimuth & Elevation Drive Assure that Azimuth angle and Elevation angle is updated by antenna movement. Test Tracking Assure that AGC value of ACU is better than normal operation condition. Assure that DVB carrier lock is stable when you use carrier lock searching mode. Visual Inspection Radome & Pedestal Conduct a good, thorough, visual inspection of the radome and antenna pedestal. Visually inspect the inside surface of the radome top and of the antenna pedestal. Look for water or condensation, rust or corrosion, white fiberglass powder residue, loose wiring connections, loose hardware, loose or broken belts or any other signs of wear or damage. 1 Radome Inspection All the radome flanges are properly sealed to prevent wind, saltwater spray and rain from being able to enter the radome. Re seal any open ( leaky ) areas with marine approved silicone sealant. If heavy condensation, or standing water, is found inside the radome, isolate and seal the leak, and then dry out the radome. Small (1/8 inch) holes may be drilled in the base pan of the radome to allow standing water to weep out. 2 Antenna Pedestal Inspection The springs and Wire Rope Isolators should not be frayed, completely compressed, or otherwise damaged. The plated and painted parts should not be rusted or corroded. The harnesses should not be frayed and all the connectors should be properly fastened and tightened. All hardware should be tight (no loose assemblies or counter weights). Replace, re coat, repair and/or tighten as necessary. Mechanical Checks Turn ACU power OFF 1 Inspect inside of radome for signs that the dish or feed have been rubbing against the inside of the fiberglass radome

90 2 Rotate the pedestal through its full range of azimuth motion. The antenna should rotate freely and easily with light finger pressure. 3 Rotate the pedestal through full range of elevation rotation. The antenna should rotate freely and easily with light finger pressure. 4 Rotate the pedestal through full range of cross level rotation. The antenna should rotate freely and easily with light finger pressure. 5 Rotate the level cage through the full 90 degrees of rotation from CCW stop to CW stop. The level cage antenna should rotate freely and easily with light finger pressure. Attached cables should not cause the cage to spring back more that a few degrees from either stop when released. 6 Inspect all drive belts for wear (black dust on/under the area of the belt). Check Balance Check the balance of the antenna, re balance as needed. Observer Antenna Initialization Observe the Antenna Initialization as described below. Turn the ACU power supply ON. The PCU will initialize the stabilized portion of the mass to be level with the horizon and at a prescribed Azimuth and Elevation angles. The antenna will go through the specific sequence of steps (listed below) to initialize the level cage, elevation, cross level and azimuth to predetermined starting positions. Initialization is completed in the following phases, each phase must complete properly for the antenna to operate properly (post initialization). Observe the Initialization of the antenna pedestal. Step 1. The level platform motor drives the Level Cage CCW, issuing extra steps to assure that the cage is all the way to the mechanical stop. Then the Level Cage will be driven exactly 45.0 degrees CW. If level Cage movement make noise and is not smooth operation, then check step motor driver. Step 2. Elevation axis then activates Input from the LV axis of the tilt sensor is used to drive the Elevation of the equipment frame to bring the tilt sensor LV axis to level. This step takes approximately 10 seconds and will result in the dish being at 45.0 degrees in elevation. The level cage may still be tilted left or right at this time. Step 3. Cross Level axis activates Input from the CL axis of the tilt sensor is used to drive Cross Level of the equipment frame to bring the cross level axis of the tilt sensor to level (this results in the tilt of the Cross Level Beam being level). This step takes approximately 10 seconds

91 Step 4. Azimuth axis activates Antenna drives CW in azimuth until the Home Flag signal is produced. This signal is produced by a Hall Effect sensor in close proximity to a Magnet. After another 10 second wait, the antenna will report its version number at the Antenna Control Unit (ACU). This completes the phases of initialization. At this time the antenna elevation should 45.0 degrees and relative azimuth should be at home flag (home switch engaged on the home flag cam). If any of these steps fail, or the ACU reports error message, re configure the PCU as described in the Setup section of this manual. If error message indicates a drive or sensor problem, refer to the Troubleshooting section. Satellite Reference Mode or Gyro Failure Mode The ships gyro compass input to the ACU may be accurate and stable in static conditions and yet may NOT be accurate or stable enough in some underway dynamic conditions. If there is no gyro compass or if the input is corrupt, not stable or not consistently accurate the tracking errors will become large enough to cause the antenna to be mis pointed off satellite. Gyro Failure Mode in PCU GYRO MODE (Satellite Reference Mode) will uncouple the gyro reference from the azimuth rate sensor control loop. When operating in Gyro Failure Mode changes in ships gyro reading will not directly affect the azimuth control loop. The Pedestal Control Unit will stabilize the antenna based entirely on the azimuth rate sensor loop, sensor fusion loop and the tracking information from DishScan. This will keep the azimuth rate sensor position from eventually drifting away at a rate faster than the tracking loop can correct by using the tracking errors to regulate the rate sensor bias. Gyro Failure Mode can be used as a diagnostic mode to determine if tracking errors are caused by faulty gyro inputs or no gyro compass situation like a truck and GPS compass etc. Dishscan Result Start Point Figure 10-1 Dishscan Concept
