So I had a SWM 16 put in a couple months ago when I got a genie. I have 3 DVRs and a genie. I move boxes and cables when football comes so I have have tvs in basement. well last time Directv was out they moved a lot of wires and cant figure out what goes where. where can the cables that go out to the boxes be located? on the channels 1-8 and 9-16 only? the middle one says DC power so can I use that one? the channel 1-8 has one cable to it and it runs to the genie. then there is a splitter on the 9-16 and runs to a 4 way. that 4 way is full. I wanted to add a cable or two to run to spot that I will have tvs. leave them all connected so I don't need to mess with the cables, just the boxes. Any ideas where I can throw these other two cables? do I have to split the channel 1-8 one also. just asking cause there is a whole lot of unused stuff on this swim 16 and didn't know. Thanks.
