I found a Show Me Cables product called "Choice Select 8-Port IR Distribution Hub"
It has 8 "From IR emitter" connections - each connection has 3 pins (+ - S).
It has 8 "To IR emitter" connections - each connection has 2 pins (+ -).
It seems (to me) that the product allows up to 8 IR transmitter with the same signal characteristics (38 khz modulated IR light) to drive 8 separate receivers - but I don't understand how it works or how it is wired to the IR TX and RX components. The "features" list states "Single band targets only". Does anyone know if this could be used in my application? I don't see where the "wireless" part comes in unless it modifies the IR channel signals to be uniquely identified by receiver components? But, if so, wouldn't it require specially matched receivers?
