When I purchased my 31sl, I spent almost an entire day tracking the cable and satellite system. I had to go to Home Depot and buy a toner to track and label each cable. I found one of the connections for Satellite in the outside convenience center went to the bedroom and one to the living room. I do not use a remote satellite dish so these are really not in use but I did label them for future use if I get a portable dish (I have a roof mounted Traveler automatic dish that services both rooms). The Cable was not connected to the TV's and had to be connected.
When connected to Park Cable, you must make sure that the power antenna is OFF and you must go to the input setting on the TV, select cable without a box, and do a channel search before you can use it. The Remote satellite antennas typically only can service one receiver so you need to know which input you are on. To confuse things more, I have a cable that goes from the Living Room to the Bedroom not in use.
Without a toner, I do not think we could have figured it out. Hope that helps a little, it is a common frustration found on this forum.
