I have a PMDX-107 that doesn't seem to be sending anything to the J1 connector. All the lights flash like they should in test mode, but when I connected it to my motor control adjusting the pot doesn't change the motor speed. I am also using the Run/Com ports to flip a PMDX-ContactorMD20-120 on. I tested the PMDX-ContactorMD20-120 using 120v and it does flip but not when its connected to the PMDX-107. I checked between Run and Com using a multimeter and there isn't anything when its in test mode. I also checked between Aout and Agnd am I doing something wrong or is the board bad?

I have a LabVolt 5600 which I am retrofitting I am trying to figure out how to connect the D&M Computing Chopper Driver.

There are four wires coming off the driver they are:

A yellow wire goes to a terminal on the driver labelled "D"
A grey wire goes to a terminal on the driver labelled "C"
A black wire goes to a terminal on the driver labelled "-"
A red wire with is goes to a terminal on the driver "+"

+ is 5VDC I am not sure how to connect the - wire should I connect that to the machine ground? I Think PCground wont be connected on this machine to anything since I am using a UC400ETH to connect to the pc. I think - might be the neutral side of a 5V circuit.
