Ahh, thanks, that makes everything clear, or so I hope. Thanks for the link - I was looking for that information (I was going to the "Operator Interface" link rather than the entire control systems link). Anyways, I think I have the electrics diagram right now that we know what pins do what, but then again, electrics isn't my strongest subject. Can you take a look and make sure it's right before I go and fry our OI?
