Mpg wont work

Will

I have a ddcsv 3.1 with mpg I bought as a set. Qhen I plug in the mpg nothing works . The motors estop nothing. The estop is enabled  and all the seeting for mpg I ja e tried every combination. Any ideas. The green light is on so it has power. And I checks that all the wires have continuation.
Thanks

Solved...I did not realize that the mpg need the xoma ports energized....
