Hello Steve,
With our HiCON Integra, the easiest way to connect an MPG to the system is to use the MPG06 that we provide on our website because it's pretty much plug and play.
Otherwise, you'll need to hook up your MPG's encoder input to either J11 for a differential encoder, or J6 for single ended. Aside from that, if your MPG has selector switches, you may connect those to the digital inputs.
For configuring the MPG settings for Mach4, see the Mach4 Integration manual available on the HiCON Integra webpage.
