Mounting Instruction Compact Mini EGC Amplifier 93230 and 93240 Application The Compact Mini EGC Amplifier type 93230 and type 93240 has one active output and is mainly used as distribution amplifier. The only different between the two types is that ROSA Element Management System cannot monitor the 93230. All equalizers and pads are electronic and can be set with the handheld terminal type 91200. The plug-in filters in the reverse path allow flexible choice of frequency range for both forward and reverse path.

To Mount the Amplifier CAUTION: Be aware of the size and weight of the amplifier when mounting. Ensure that the mounting location has a stable flat surface, and can safely support the amplifier s maximum weight. Please use the appropriate type of screws and screwdrivers, depending on the mounting method. Mounting Material: The amplifier should be mounted vertically with the cable input underneath, to allow natural ventilation and to secure the best possible operation conditions. Use a 4 mm Allen key for screw in lid and fasten with 5 Nm. The pin length of the PG 11 cable connector at input and output is shown on the cover plate of the amplifier. The amplifier can be mounted on the wall of concrete, brick, wood, metal, etc., or in the cabinet. Mounting Steps: 1 Use two mounting screws to mount the amplifier. The screw size is M5 and the distance between two mounting screws is 166 mm. 2 Tighten the two mounting screws. Make sure the amplifier is fixed steadily.

Please Notice: Plug-in units This product can only be setup with a hand held terminal type A91200.11 or with a hand held terminal type A91200.10 containing the necessary driver for the EGC amplifier. New drivers can be installed by means of download kit A91210.10. Three plug-in units are necessary. Two diplex filters type 75130 with the required split frequency. Use two links type 74089 if the reverse path not is used. Plug-in reverse equalizer type 74141 with the required filter frequency determines the frequency range for the built-in active reverse path. 230 V AC DC AC or DC in DC 0-18 db Equalizer or Cable simulator -9 to18 db 0-6 db 0-15 db µ- Controller TX Transponder RX -33dB 0/6/ 0-18 db Rev.Eq. 0-15 db 0-20 db TP TP Rev.

Power Supply 230 V (or 115 V) Mains Supply The amplifier has factory mounted mains cable and plugs, which according to approval provisions may not be altered. The power unit is double insulated, and supplies only this single amplifier. When the power unit DC voltage lights indicate the power unit is supplying correct DC voltage. Remote Supply 24-65 V AC (or 35-90 V AC) The amplifier can be supplied with 24-65 V AC either via coaxial cables (max. 5 A) or directly to the AC input (max. 7 A). AC Pass On delivery, ports are provided with insulating fuses. Desired AC pass is obtained by turning the fuse holder after connecting the cable or before disconnecting, to prevent damage of cable connectors. Permanent excess of max. Remote current implies a risk of damage. Low Voltage Lockout For all coax line powered power supplies an undervoltage switch type 75018-xx can be delivered that switches off the power supply if the voltage drops below the rated value (24 V or 35 V) thus, the network is not damaged due to increased current consumption. Setting up the amplifier The hand held terminal type 91200 is used to set up the amplifier. Use the menu structure below to navigate through the different menus. Shortcuts Use the short cuts shown on the cover plate to do a fast selection of the required menu. Ex. The output equalizer is marked with 5. By pressing the button 5 in approx. 1 sec. the terminal returns to the menu where the output equalizer can be is changed. The menu numbers can also be used as short cuts. Please see the menus structure below to determine the number for the required menu. Ex. Press 35 and the handheld terminal will return to the menu where the reverse switch can be set. 4010069 Rev F Mounting Instructions Compact Mini EGC Amplifier 93230 and 93240 5

ROSA Element Management System in Type 93240 Monitoring of the amplifier requires the installation of the transponder type 91051 in the amplifier. This transponder will communicate back to the head-end by means of the reverse path. The transponder signal is received at the test point at output. Please see fig. 2. The level measured by the transponder will be attenuated by approx. 33 db relative to the output signal at output. The transponder transmitter level is adjusted to the same level as the other reverse signals. The level from the transponder will be attenuated by approx. 20 db at the reverse path since it is inserted with a 20 db coupler. With a transponder it is possible to monitor and control different parameters in the amplifier. As seen in Fig. 2, the built-in reverse path switch can be controlled in order to locate ingress noise in the reverse path This can be useful in the search for errors in larger networks. Programming of a Compact Transponder type 91051 is done by using the Handheld Terminal 91200. The transponder can be set with: SMC ID Transponder adress 1-65535 TX FREQ Transmit frequency 5-65 MHz RX FREQ Receive frequency 45-174 MHz TX LEVEL Transmit level 84-110 dbµv BAUD RATE Data speed 9.6-19.2-38.4 kbps MODE Transponder mode IEP Accessories Test adapter, F type A71004 Fuses 2AT, for 230 Vac A38008 2AT, for 115 VAC A38024 3.15AT, for 24-65 V (35-90 V) A38010 6.3 AT, for input/output port A38015 4010069 Rev F Mounting Instructions Compact Mini EGC Amplifier 93230 and 93240 7
