Great, thanks Steve, I look forward to your results...

The more i think about it, I can't see why you'd need the 4 IR receivers... it sure would seem easy to run one of the IR receivers to each of the blinds input port (assuming you always want them to rise/lower together)... is that your goal also? Seems you could split the wires to each receiver... sure would help if HD had a pin diagram in the manual or on their tech website. they don't, i checked.

Alternatively, wouldn't it be wonderful if the 4-wire receiving port on the blinds simply accepted a standard 4-wire run from an IR connecting block? It's quite possible... then you'd have it fully hardwired...
