On my Flagstaff 8529IKBS there is a Satellite FEED to the bedroom, on an outlet plate next to the over-the-air antenna plate in the living room entertainment center.
I have to feed the satellite receiver's video signal to the bedroom using that port. I then connect the bedroom tv to the SAT port in the bedroom.
This set-up allows the bedroom tv to watch the same channel of the satellite receiver as the living room tv.
If you are wanting to connect a slave receiver such as a Genie, you'll need to use that port to feed the slave receiver to the bedroom from the master receiver.
Every R/V is different though so no two are seemingly wired the same.
