Here's a challenge I'm having a hard time solving without resolving to custom circuits. I've got a Harman Kardon PA4000 eight channel amp (4 stereo pairs). I'd like to control each stereo pair volume independantly using the available IR input for each set of channels -- 1 IR receiver going into each of 4 zones around the house. This way I can carry the same remote around the house and adjust volume for each room as I am in it with the same remote (just using the volume keys). The HK allows control via the 4 IR inputs or 4 keypad inputs (custom RJ45 circuit). Each input controls a discrete set of channels, but each input also recieves the same commands as the other -- there is no address for each IR.
Make sense? Now comes the hard part:
I'd like to also be able to control the volume levels for each of these 4 stereo pairs from my home control program. I'm having difficulty finding a device to read in IR signals from 4 different locations to a computer (where my home control program is) that can also send out signals to each of these 4 IR ports WITHOUT sending them all the same info at the same time! By this I mean that each port must be discrete. This comes to be a problem when the IR codes are the same for divices you want controlled discretely.
I found a device called a Tira-2.1 that seems to be able to act as both IR reciever and transmitter, but I'm not sure if I can use something like 4 of these plugged into the same computer or what.
Any ideas? Much appreciated -- I'm not beyond hardwiring up custom mux's at this point
