Segmented Return 
In the segmented return configuration each RF return is applied to an individual RF input on 
two SG4-DRT-2X transmitters. Two segmented return boards are required. The segmented 
return boards contain two independent RF paths. In a typical installation, the RF modules in 
Ports 1 and 3 are connected to the segmented return board in return configuration location 2. 
The RF modules in Ports 4 and 6 are connected to the segmented return board in return 
configuration location 3. The segmented return board installed in return configuration location 
2 directs RF to channels A and B on the SG4-DRT-2X located in lid optics slots 3 and 4. The 
segmented return board in return configuration location 3 directs RF to channels A and B on the 
SG4-DRT-2X located in lid optics slots 5 and 6. 
Figure 12 illustrates the segmented return configuration:
