Has anyone used the C22M1 Modbus MPG interface card from CNC4PC with the latest version of UCCNC?

I get unstable jogging, moving the mpg wheel one detent will make the selected axis travel one inch then the axis will reverse movement by itself and travel .250" back. If the mpg wheel is moved several detents the selected axis will go into runaway mode and will not stop until a limit switch is contacted or I hit the E - Stop.

The C22M1 has been setup asper the very limited manuals from CNC4PC. Is there some settings that I need to setup in UCCNC for this to work properly?
