[amsat-bb] G-5500 Rotor Alignment Problem

I finally got up and running with a new G-5500. In running SuM from the SatPC32 applications and then verifying the problem by tracking a satellite I find that the AZ rotor is going to the wrong position every time. It seems to be about 245 degrees off. I've verified that things are wired correctly and CCW and CW are correct. What am I doing wrong? The old G5400B worked fine.
