Figure 7 illustrates the 2X redundant return configuration board. Jumpers J5 and J6 are shown in the normal default position. Jumper J6 enables/disables signal flow to output connector

J8 (Tx2). Jumper J5 terminates input connector J3 (IN2) when only a single RF input is used.

To set up the split return option:

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

2Confirm that a 2X redundant return board is installed in lid return configuration board locations 2 and 3 as illustrated in Figure 5.

3Position J6 in the right-most position to terminate the output to transmitter two.

4Connect an RF cable from the 2X redundant return board, in lid return configuration board location 2, to CH B of the SG4-DRT-2X .

5Connect an RF cable from the 2X redundant return board, in lid return configuration board location 3, to CH A of the SG4-DRT-2X.

The RF cables should be approximately eight inches long and have red boots on the connector signifying the return path.

6If necessary, connect the appropriate return RF cables from the SG4-RF modules to each 2X redundant board.
