I think I get it now. I'm at work so I can't confirm this. This is my first PE type of device so bear with me..

I was under the assumption that the entire channel (THO) port was dedicated to powering the PE. However, based on your reply and my recollection of the gizmo, there are three pins for the conenctor. TWO pins provide + and - power to the PE. The third wire does the servo signaling just like most of the rest of the single wire conenctors on down the line, until the next batt connector.

Cool, thanks rrritchey.
