@sccues if you're looking for the pin out of the cable to mocon/maincon board to vector drive is to find the cable number on the cable itself and then look in the service manual sometimes they will have a detail pin out on each end of the cable. Also are you retrofitting the control to a mach4 because of cost or due to you're more familiar with it? Either way retrofitting the control to something other than what Haas has designed it's components for its super risky and I hope it's goes well, but you may run into some major issues unless you're replacing every little thing from cables,boards,amps,inputs/outputs, and power distribution throughout the control.. good luck
