LBI-39128

Sensor interface module in the EDACS Repeater cabinet containing the transmitter for channel #11 or #13). If the two cabinets are next to each other in the same row, use a 5-ft 19D903880P120 cable. If the two cabinets are across from each other in different rows, use a 15-ft 19D903880P121 cable.

10.Starting with the cabinet containing the transmitter for channel #11 or #13, follow the daisy chain of 25-pair cabinet interconnect cables connected to J14 and J15 on the Power Sensor interface module in each EDACS Repeater cabinet until an empty J14 or J15 connector is found. Plug the 19C852379G1 Channel Termination Board (removed in the previous step) into this empty connector.

11.Remove a shorting jumper in the 19C852379G1 Channel Termination Board for each transmitter channel # equipped with a power sensor (P# plus 12 corresponds to transmitter channel #). Note that the P# corresponds to a different transmitter channel # in this case.

Note that there is a shorting jumper for transmitter channels #11 and #12 on each of the 19C852379G1 Channel Termination Boards. Therefore, if transmitter channel #11 or #12 is equipped with a power sensor, a jumper must be removed from each of the two channel termination boards.

12.Connect the five new 188D6466P2 cables from J3 through J7 on the Power Sensor interface module in the upper EDACS Interface Panel, to Port 1 through Port 5 respectively on the back of the PMU.

13.Connect the new 188D6466P1 cable from J8 on the Power Sensor interface module in the upper EDACS Interface Panel, to PORT 7 on the back of the PMU.

14.If the Site Controller computer has modular RJ11-8 connectors on its back panel, connect the new 19D903880P101 cable from the right-hand VDT Interface on the back of the PMU, to Port 29 on the back of the Site Controller computer.

If the Site Controller computer does not have modular RJ11-8 connectors on its back panel, connect the new 19D903880P100 cable from the right-hand VDT Interface on the back of the PMU to connector #13 on the right-hand (B) DILOG panel (above the Site Controller computer).

15.Install the 19C336861P3 or P4 antenna power sensor(s) at the output of the transmitter combiner(s) in the RF Equipment cabinet(s).

16.Install the 19C852677P1 antenna power sensor cable from J9 on the Power Sensor interface module in the Site Controller cabinet, to the antenna power sensor(s) in the RF equipment cabinet(s) as shown in Figure 9. If the system has only one antenna, tack solder a jumper (tip to shield) on each of the unused phono plugs to short the forward and reflected power sensor circuits for antenna #2.

17.Double check the installation using the interconnection diagram shown in Figure 10.

18.Set the power switch on the back of the PMU to the “Off” position.

19.Turn on the main 12V power supply for the cabinet.
