The mode switches are set in the RS232 mode.
The output module of the first RCVDS05 has to be programmed when a Video or S-

If a component video or RGB analog source is selected, these signals are available
on the output module of the first RCVDS05 on the R, G, B BNC's.
Actions to be taken by the computer :
- select the expansion module in the first RCVDS and in the second RCVDS (with the
cat. I commands).
- select an input module in e.g. the third RCVDS05 (also cat. I commands).
- Read with the command Read_Source (4AH) the source type in the 3th RCVDS.
The returned bytes DAT1 and DAT3 give information about the source type and the
