I'm not really against the resistor idea, the 7i73 p1 and p2 cables are routed to a terminal strip, then my switches and mpg connect to the term strip, so it's not ideal, but if you could provide the data for the resistors, I can install them and keep moving along.
I would attach one end between the switch and terminal block and the other end to the 3.3vdc from the 7i73 card right? On 4/13/2015 11:42 AM, Peter C.
