I just purchased a new camper and I have room for another TV in the front bedroom, I had Dish network set up in my last camper. It is a dish 500 with a dual receiver, when I hooked it up in the new camper I hooked the dish to the port on the outside of the camper that feeds a main plug in the camper living room, I separated the cables in that box one from outside and the other 2 were for the front bedroom and back bedroom. I connected the outside cable to the satellite in which is split at the boy box to the satellite in, then connected the out to the back bedroom and that receiver works fine it controls 2 TVs. I decided to add another receiver to the front bedroom. I split the cable coming from the outside one half to the dual receiver that is located right there and the other half to the cable in the box going to the front bedroom I then connected my receiver in the front bedroom to the wall and out to the TV, I called Dish and had everything activated when I turned on the TV it said there is a problem with my connections I hit cancel and the error 129 screen came up please activate I checked with dish and it is all ok, so where did I go wrong why does one receiver work and the other is it because I split the outside connection. When the dish was originally installed the installer used a orange cable that was a double meaning it has 2 cables built into one but when it is hooked up I am only using one of the connections that was the way it was with the other camper
