Jason,

That's what I was after. I suppose I could just use GPIO lines to control relays or transistor circuits to run things like the compressor till I understand the serial part of things.

Is there anything you can point me to, to get a better understanding of the serial protocol?

As I said originally, I'd love to just gin up a specialized Arduino shield that makes cRIO swapping just a take out/plug in kind of situation.
