4 SECTION 1 Description The Translator feature changes the basic function of the CPlus series decoders. The CPlus Translator converts an ANI burst FleetSync, GE-Star, or DTMF (referred to as Incoming ANI ) into MDC-1200 so that the signal can be decoded at a dispatch console capable of only MDC-1200 signaling. The Translator operates in parallel with the Audio In of the console. The parallel configuration means that the console will see Incoming ANI and the translated MDC-1200 data bursts. The translator does not stop the Incoming ANI bursts from reaching the console. The Translator contains a Mute Relay to allow most of the incoming data burst to be silenced at the console speaker audio. The effectiveness of the muting function is highly dependent on the console audio circuitry. Depending on the console, the incoming data bursts may or may not be heard by the dispatcher. Voice audio will pass directly to the console. Voice audio does not pass through Translator. Voice audio is not muted or affected in any way by the Translator. The Dispatch console will normally hear 2 data bursts. The 1st will be the Incoming ANI data, the 2 nd will be the MDC-1200 burst. The processing time of the Translator creates a delay between the data bursts that prevents any overlap of the 2 data bursts. Page 4

5 Operation Example: A unit in the field with FleetSync signaling keys up and his PTT ANI is transmitted. At the Translator, the FleetSync ANI is decoded and converted to MDC-1200 and the resulting ANI burst is injected into the audio path approximately 300 ms later. As FleetSync is not recognized by the dispatch console it is ignored and the MDC translation is displayed at the console. Notes: The RS-232 serial port is for initial set-up only. Can be implemented with a CPlus I, II, III, or MCI. C Plus series takes in FleetSync or GE-Star or DTMF and always outputs MDC-1200 Alias option not available with the Translate option. No Acknowledgements, no sounder, no contact closures. No special reactions to Emergencies (no acknowledgements) FleetSync s 3 digit Fleet ID will be ignored. Not compatible with FleetSync II. Page 5

For use only in Single Ended systems. JP-13 Out Adds 18db of attenuation to the Data In signal. For use only in Single Ended systems. Jumpers JP-13, 12, 11, 10, 9 and 8 set up attenuation circuits. Only one of these jumpers should be installed. JP-11, 12 and 13 are for Single Ended systems and JP-10, 9 and 8 are for Balanced systems. Page 9

10 SECTION 5 Data Input - Details Data input is the signal input to the C Plus. This is Receive Audio from the radio. Data In + is the high side and Data In - is the low side. Data input is jumper selectable for high impedance single ended, high impedance balanced and 600 ohm balanced. In nonbalanced configurations, Data In - is referenced to ground. However, note that it is not directly shorted to ground. In balanced systems, it is signal return. Always attach an independent station ground to the rear panel P3 pin 8 or P2 pin 10. The input is capacitor coupled for DC blocking and is MOV protected. When interfacing to a radio, connection should be receive audio, before de-emphasis (flat audio). Data input + should be jumped for high impedance and data input should be jumped to ground. If connected to a balanced line, remove ground jumper JP-7. Data input is AGC conditioned so generally, no adjustment is necessary. A test point is provided for oscilloscope connection. If the signal is clipped and distorted, a potentiometer and a bank of gain jumpers can reduce gain. Alternately, if the signal is too weak, gain can be increased. Attenuation jumpers are described below. Use only one jumper at a time. Input Signal Attenuation Unbalanced Balanced 18 db JP-13 JP db JP-12 JP-9 6 db JP-11 JP-8 Page 10

11 JP5 provides an amplification stage to increase the data input signal. Amplification factors are described below. Observed Maximum signal at TP10 Gives this amplification to input 0.05 VPP 36 db 0.2 VPP 24 db 0.65 VPP 12 db 1.6 VPP 0 db If you experience a decode rate of less than 100%, view the ANI signal waveform at TP10. Adjust the attenuation jumpers so that the waveform is not clipped. Do not exceed the absolute maximum peak to peak signal level listed in the above table. Then view the waveform at TP-7 and adjust jumper JP-5 and VR3 for a 1 Vpp ANI signal. Page 11

12 SECTION 6 Data Output - Details Data output is the translated MDC-1200 ANI burst out of the C Plus. Data output is jumper selectable for single ended or balanced configurations. In Single Ended configurations, Data Out - is referenced to ground. However, note that it is not directly shorted to ground. In balanced systems, it is signal return. Always attach an independent station ground to the rear panel P3 pin 8 or P2 pin 10. The output is capacitor coupled for DC blocking, is MOV protected and is completely isolated by relays when not actively encoding. If connected to a balanced line, remove ground jumper JP-25. For 600 ohm operation, add jumpers JP-24 and JP-27. Data output must be adjusted to ensure that the target console sees a level about the same as the un-translated burst. Rear panel potentiometer R5 is available to adjust the level. The Self-Test command $$KEYT is used for setting outbound data deviation. This command forces a 10 second burst of data from the Cplus. Page 12

13 SECTION 7 Programming The C Plus is set-up via the RJ-11 RS-232 serial connection. The RJ-11 serial connection can be used with any computer running terminal emulation software like Hyperterminal. When Using Hypertermal, characters you type will not be visible on the computer display. Upon initial power-up, the C Plus counts down for 10 seconds. After the countdown, the C Plus is ready. To program the C Plus, type: $$CPlus The Cplus display will show the word: When in program mode, the C Plus suspends normal operation until program mode is exited. The following menu will appear on Hyperterminal: Note: Not all programming items are available for the Cplus Translator. Page 13

14 Programming the C Plus Personality The C Plus is shipped with the default format type = MDC This is the correct setting to translate FleetSync, GE-Star, or DTMF. Note: Not all programming items are available for the C Plus Translator. To confirm the C Plus personality, from the main menu, type a 2 to select: 2.

GE STAR and/or Select: 5. DTMF Although the Translator is now programmed for up to 3 formats, the Menu will always return MDC-1200 as the selected format. Page 15

16 Unique Settings for FleetSync FleetSync contains Fleet ID s which cannot be supported by the structure of MDC This requires the translator to strip the Fleet ID from the received data string and forward only the unit ID. To support Fleetsync group ID translation, up to ten ID translations can be entered into the C Plus. ID translations are defined by entering the following string: $$Fxxxx=Myyyy Where: xxxx is the four digit FleetSync target group ID yyyy is a four digit MDC-1200 group ID. If a FleetSync group call is received targeting group xxxx, the translator will substitute MDC ID yyyy for that translation. For example, $$F4911=ME123 will permit FleetSync group ID 4911 to be translated into MDC group ID 123. MDC-1200 ID s that begin with E represent MDC groups. An existing table can be read from the C Plus by entering the string: $$FVIEWGROUPS The table can be deleted by entering the following string: $$FERACEGROUP If DTMF mode is selected, the following programming options must be considered: Unique Settings for GE-Star The GE-Star format has many variations which most users will never be involved with. If you believe your system to use one of the less common variations, contact the Cimarron Technologies Engineering Department and we will be glad to help you program the Translator. Unique Settings for DTMF Mode The DTMF format has many non-standard timing variations which most users will never be involved with. If you believe your system uses one of the less common character timings, contact the Cimarron Technologies Engineering Department and we will be glad to help you program the Translator. ID Qualifying is a type of filtering which is available in the Translator. If you believe your system would benefit by the use one of the filter, contact the Cimarron Technologies Engineering Department and we will be glad to help you program the Translator. Page 16

17 SECTION 8 Operation Front Panel Displays and Controls C Plus I - Translator The C Plus I - Translator is a computer interface device. The front panel consists of LED Indicators describing the functioning of the unit. The LED s and their function are as follows: LED Indicator MUTE DECODE Tx I/O ACTIVE Rx I/O ACTIVE Tx BUSY KEYED ENCODE AUX 1 ERROR POWER RESET button Meaning Lights when the C Plus detects data which may or may not decode. Stays lighted during the entire reception period. Follows the action of the Mute relay. Lights when the C Plus has successfully synchronized with incoming data and is decoding valid data.

18 C Plus II - Translator The C Plus II Translator showing a pre-translated FleetSync ID = This ID will be translated to MDC-1200 ID = Signaling Typical Translation Comments type Display FleetSync A PTT ID has been received from radio whose fleet number is 123 and ID is GE Star MDC A876 A876 MDC-1200 ID s are in hexadecimal. In operation the C Plus II will alternate between the decoded ID and the abbreviation XLAT and the decoded ID Message type. The Translated MDC-1200 ID is not displayed. Page 18

19 The RS-232 port will show the decoded ID. The RS-232 port will not show the translated MDC-1200 ID. The C Plus II has two push buttons on the front panel. The right button is labeled CLEAR and clears the display. The left button is labeled REVIEW and when pressed, steps the display through the last 20 received messages. Messages are displayed just as they were received except the left most display shows the order in which the messages were received. The most recent message will be labeled a. Subsequent messages will be labeled b, c and so forth. To facilitate speedy review, non-ptt messages alternate in 1-second intervals between ID/alias and message type instead of 2-second intervals. To clear the review buffer, press and hold the review button while pressing the clear button. The review memory will be erased. The review buffer resides in SRAM and as such is volatile. If power is lost or removed, the review buffer will be erased. Page 19

20 C Plus III - Translator The C Plus III is a multiple window dispatch display unit. The main display and its features are the same as the C Plus II. In addition to the main display, there is a secondary, smaller display capable of displaying 28 characters just above the two push buttons. This display area is user programmable to present two different features. Page 20

21 SECTION 9 Serial Port Note: The serial port is mainly for programming. However, the port will output the decoded ID slated for translation. Please contact the Cimarron Technologies Engineering Department if you plan to make extensive use of the Serial Port in your system. On the back of the C Plus, there is an RJ-11 six conductor phone jack. This port can be programmed as a printer port and be connected directly to a serial printer to record channel activity. Baud rates available are 1200, 2400, 4800, 9600 and with 7 or 8 data bits and odd, even or no parity. The C Plus can be connected directly to a serial printer. The Cimarron Standard serial output format is the default format which contains time and date information. The RS-232 port can also be used to connect to the serial port of a computer. This port is capable of two way communications, accepting commands for transmission to remote radios. The RJ-11 (6 pin modular) connector is RS-232 protocol compatible with pin assignments as described in the figure below: connection directly into a computer serial port connection directly to a serial printer RJ-11 Pin # DB-9F Pin # RJ-11 Pin # DB-9M Pin # 1 (Wht) Not Connected 1 (Wht) Not Connected 2 (Blk) 8 2 (Blk) 8 3 (Red) 7 3 (Red) 7 4 (Grn) 2 4 (Grn) 2 5 (Yel) 3 5 (Yel) 3 6 (Blu) 5 6 (Blu) 5 Page 21

22 SECTION 10 Troubleshooting Performing Self Tests To facilitate troubleshooting of the C Plus, the following special commands exist. Commands $$LOOP $$KEYT $$OUTS Definition Generates a PTT ANI message and then an emergency message in the signaling format currently in operation. Repeats for 16 seconds, one message per second. Keys the C Plus and sends data for 10 seconds in the signaling format currently in operation Causes the outputs to individually wiggle for 3 seconds each. Affects Key, RXMute, TXCtl, Out1 and Out 2. $$DISPLAY Illuminates all pixels in the display (C Plus II and III) The Local Loop-Back test ($$LOOP) generates a PTT ANI message and then an Emergency ANI message in the data format selected previously (GE Star, MDC-1200, FleetSync ). DTMF encoding is not supported and therefore, $$LOOP does not function in DTMF mode. This signal generation will continue for 16 seconds, with one message being generated per second. Emergency acknowledgments are not sent during this test. If the test is successful, the display will display the decoded messages. If an alias has been programmed for the test ID, then the alias will be displayed. Test ID s are as follows: Data Format Test ID GE Star 8888 MDC FleetSync DTMF Not Supported To prepare for the local loop-back test, disconnect the C Plus from the attached communications system and connect Data Out A to Data In A and connect Data out B to Data In B. Note that once the emergency message is received, subsequent PTT ID messages will not be displayed unless the clear button is pressed. This is because critical messages must be cleared manually from the display. Serial output, however, will display all messages received. The Data Modulation Test ($$KEYT) is used to adjust data output for the proper deviation level. When selected, the C Plus will activate the Key line and send 10 seconds of pseudo-data in the data format selected previously. Output level should be adjusted so that data deviation is equal to or just below voice deviation. The Output Line Test ($$OUTS) wiggles output lines to allow verification of operation. (Key, RXMute, TXCtl, Out 1, Out 2). This test should only be performed when the C Plus is not connected to an associated radio. Each of the above mentioned lines will be Page 22

23 brought active for 500ms and then inactive for 500ms and then active for another 500ms. This cycle will continue for three seconds for each line. Only one line is wiggled at a time. Installation Hints The C Plus is AGC controlled and generally requires no adjustments to the receive signal. However, if you are having a decode rate of under 100%, try performing the following steps. Refer to the main board schematic. Notice that there are attenuation networks controlled by JP13, JP12 and JP11 (for unbalanced systems) and JP10, JP9 and JP8 (for balanced systems). Also notice that after the attenuation networks, there is an amplifier (U9B) whose gain is controlled by jumper placement on JP5. Use an oscilloscope to view the ANI signal waveform at TP10. Adjust the appropriate jumpers in the attenuation circuitry so that your waveform is not clipped and maximum values are not exceeded. Now view the waveform at TP7 and adjust jumper JP5 and VR3 for a 500mV p/p ANI signal. Isolating System Problems Timing is very important. If you have system problems, the first place to spend your energies is with timing issues. Check attack delay in repeater systems. Start with a long delay that gives you 100% decode and then shorten it up. Voting systems can add distortion which our digital signal processor can overcome. But if the voter votes in the middle of a data burst, the data will probably be lost. In all installations, ensure that station ground is attached to either P2 pin 10 or P1 pin 8.Power Supply Schematic Page 23

26 APPENDIX A Mute Relay A Mute Relay is available to assist in silencing most of the ANI burst heard by operators and dispatchers. The Relay activates as soon as the incoming data (FleetSync, GE-Star, or DTMF) is determined to be data and not random noise. The determination takes around 50 ms. When the operator s speaker is passed through the Mute Relay, a good portion of the incoming data will be silenced. The operator will however, hear the 50 ms of leading data burst. If the console has a MDC-1200 muting function, then the operator will not hear the MDC-1200 data burst. The following timing diagrams illustrate how the Mute Relay reacts. Cimarron Technologies Engineering Department will be happy to assist in planning a Mute scheme for your site. Page 26
