Ah, I saw that before but I didn't process that that was supposed to be the pinout. A verbal description just gets lost in my head of trying to describe a pinout, I thought you were saying he actually had a real pinout diagram, hence the question. My mistake, yeah it tries to describe one using normal grammar....not my forte, pass.

A more succinct description, based on the pinout in the Hardware Developer's Handbook, is that each pin with "IN" in its name is wired to the corresponding pin with "IO" in the name, and each pin named "SEND" is wired to the corresponding "REC(eive)" pin. I still don't know what they are doing about power ground.
