Ryan,
OK, I have now connected pin 1 on the BluAC5 to the Aout1 on the UMI and pin 2 on the BLuAC5 to the Aognd on the UMI. I have made the encoder connections as you suggested and checked the encoder counts in MAX. It counts correctly up for CW and down for CCW. I have set the BluAC5 to velocity mode (differential) and I am now able to do controlled moves from MAX! Now I just have to figure out some of the fine tuning needed.
Thank you so much for your help and patience.
Regards
Andre
