I have a SWM Home Network with 2 HD-DVRs and 1 HD receiver, all connected to the network and each other via DECA adapters. This all works fine. I also have some other 'active' DirecTV outlets in some other rooms that aren't currently connected to anything. Is there any way I can use these outlets to connect other devices, e.g. computers, to the home network without a HD receiver. I have some extra DECA adapters. I tried to connect the DECA to the COAX outlet but the power light doesn't come on; I assume the power comes from the HD receiver. Can I somehow use the outlet without a DECA adapter? Suggestions appreciated.
