I hadn't really changed anything.  I was switching Rutex boards around to determine if one of them was bad.  In the process, the Campbell board began giving me bad indications.  Long story short, I have at least one bad Rutex board and now it appears I've lost the Campbell board.
Rutex is no longer supported, the Campbell board is outdated and my version of it has a bad rep.  Sooo... Rather than putting any more time into this house of cards, I'm starting over again....
I've ordered the PMDX-126 breakout board, three Gecko 320's, and a 73V 20A pancake power supply.  Looking forward to getting this stuff and going at it again.  I'm sure I'll be back, at least to let you know how it goes.

thanks for all your help, rex

I know the 126 is a great product! You didn't go wrong there.
