Split Return

In the split return configuration, each pair of RF returns is applied to a separate 2X redundant return configuration board. In a typical installation, the RF modules in Ports 1 and 3 are connected to the 2X redundant return board in return configuration location 2. The RF modules in Ports 4 and 6 are connected to the 2X redundant return configuration board in configuration location 3. The 2X redundant return configuration board, in location 2, directs RF to CH B of the SG4-DRT-2X. The 2X redundant return configuration board, in location 3, directs RF to CH A of the SG4-DRT-2X. The same configuration board is used in the split redundant return configuration explained in the next subsection.

Figure 6 illustrates the split return configuration:
