I built my own IR repeated a number of years ago and found it in the bottom of my junk bin. It was based on the GP1U52X IR detector. See the attached schematic. Can I replace the GP1U52X with the stereo Y splitter and the 2 detectors I have that came with my Comcast digital cable adapters?. What factors are involved in being able to run multiple parallel detectors? Also since these detectors are plastic encased units with a stereo (3 conductor) plug on the end, how do I determnine which pin is Vcc, Ground and Signal? Do I risk damaging it if I use trial and error to connect it to my repeater? If I can't simply connect them through a Y splitter, any suggestions on a mod to the circuit to support 2 detectors? Any help or suggestions is greatly appreciated.
