Is there such a thing, or can I hack an IR repeater > to act like this? I'm actually doing this with one of my htpcs. I built a homebrew serial IR which is @ the tv, then it runs over cat5 to the box which is roughly 60ft. away. In total it signal goes through: tv -> 3ft to wallplate connector -> about 60ft run outside -> wallplate connector -> 4ft to serial port. It works here just fine with only the wire. The only problem I had was making sure the HDMI cable from the box to the tv didn't run along side it. I'm guessing the reason it's not working for you is cable quality. I don't think it makes any difference which wires I used in the cat5 but I can check if you like. |
