Has anyone used the above combination? I had a pmdx411, gecko g540 and mc60 working on my lathe.  Needed more outputs and switched to Pokey57CNC.  The g540 had 3 wires to the mc60, the +10v, common and 0-10v to regulate the spindle speed.
I am electrically illiterate and cannot figure out how to wire the pokeys board to the same mc60 speed controller.  I have the white connected to pokeys 0-10v output but don't know where the black and red wires should be connected.  Any guidance would be greatly appreciated.

TIA

Solved.  I had it wored correctly but one of my solder joints had broken under some shrink wrap.
