Double rear connector modules
Double width rear connector modules are sometimes required to allow sufficient space
for the connectors used for certain signal types. There are three types of double width
connector modules for the SV. For example, the RM-SV100 Video Loop rear module
needs 8 x BNCs plus a 9 pin D-Type connector. This requires twice the space compared
with the RM-SV20 video input rear module, which has 4 x BNCs and a 9 pin D-Type
connector.

When using the double width rear connector modules, the video loop card is always
required. This is because the system architecture requires video signals to pass through
each card slot position. If a video loop card is not fitted, there would be an empty slot in
the frame and no path for the video to pass though.
The example above illustrates the signal path when video input cards occupy each card
slot. This configuration is correct.
