Okay first lets pretend I have no idea what I am talking about. But, I believe the MPG interface only interprets (receives) the pulses sent from the handwheel. The x1/10/100 function is an electronic manipulation of the pulses generated at the handwheel itself, and the electronics reside entirely within the handwheel. Let's see how long it takes someone to tell me how wrong I am. Meanwhile if I get some time I will review the schematics for my Delta50. I don't have a handwheel and it is older than yours, but it may give some clues as to how the handwheel and control interface.
