I have a Comcast digital adapter that came with a remote sensor that plugs into it (3 conductor 1/8" plug tip is +5 vdc, ring is signal, and collar is ground). I would like to be able to control the adapter from two locations. I tried to use a stereo Y splitter to connect 2 sensors into the single jack on the back of the unit, however when both sensors are plugged in, neither works. If I unplug one, the other works fine and visa versa. Any ideas how I can get both to work? I'm on a very limited budget, so buying other expensive equipment is not an option. Is there a simple circuit that would take the input from either sensor and pass it on to the adapter?
