Figure 10 illustrates the plug-in board required for the 2X redundant return option. Jumpers J5 and J6 are shown in the correct position. Jumper J6 enables signal flow to output connector

J8 (Tx2) when in the left-most position. Jumper J5 terminates input connector J3 (IN2) when only a single RF input is used.

To set up the split redundant return option:

1Confirm that SG4-DRT-2X transmitters are installed in lid optics slots 3 and 4, and 5 and 6.

2Confirm that a 2X redundant return board is installed in return configuration locations 2 and 3 as illustrated in Figure 8.

3Position J6 in the left-most position on each configuration board to enable the output to Tx2.

4Connect an RF cable from connector TX1 on the 2X redundant return board in configuration location 2 to CH B of the transmitter in lid optics slots 3 and 4.

5Connect a second RF cable from connector TX2 on the 2X redundant return board in configuration location 2 to CH B of the transmitter in lid optics slots 5 and 6.

6Connect an RF cable from connector TX1 on the 2X return redundant board in configuration location 3 to CH A of the transmitter in lid optics slots 3 and 4.

7Connect a second RF cable from connector TX2 on the 2X return redundant board in configuration location 3 to CH A of the transmitter in lid optics slots 5 and 6.
