Yes just wrap the receiver & emitter each in a dedicated enclosure (or possibly shrink wrap). You must isolate each emitter from each receiver ecept the one is is meant for. Perfect for my un-punched RJ-45 connector shields.... Interestingly, with external logic gates you could simplify things ...

Maybe there is an easier solution surrounding firmware writing... after thinking this through, it may just be possible to ignore emitter output when the receiver is busy. The user of a second, third, forth, etc... remote would simply press the command button on the harmony again. Clunky but may just...

Thank you, I was concerned about the IR emitter voltages, as you say, they are less than 3V. Someone mentioned that if I had the emitters "taped" to 8 receivers, then I could parallel the receivers into the processor. I would Imagine the same problem would exist and would still need to cap...

Several possible approaches....depends on how hardware is configured etc. So first post a hardware connection diagram/layout, showing: - how is the IR transferred over HDMI. (Modulated, demodulated, serial data or similar). Does is come out in the rack as IR (or ?) - physical connections to Arduino...

Hi folks, I'm looking for direction on creating an Arduino sketch/project to help solve a unique problem. What I have are 8 separate IR Emitter signals coming in from 8 classrooms over HDMI baluns to an equipment rack. All 8 of these are pointed to one IR Receiver. This IR receiver is communicating ...
