Wiring the IR Receiver

If you put it on a 12V circuit, you give it a 5V leeway, which is pretty good.

We just took the digital in/out and bridged 14 and 15 ground and power to our IR board and it was working with no problems (and this way your nor running off of your backup and your still giving the board 10 volts... also minimizing wire runs)
