I was wondering if anyone on these forums has any experience with setting up a multiplexer.
We have hard gauges with DTI's on them which connect to a multiplexer and then that connects to a pc and into the SPC software. I am running windows 7 on the pc and I am thinking this is where the problem lies. basically the multiplexer connects via RS232 port, when this is plugged in nothing seems to happen, no additional devices in device manager or anything. I have tried using hyperterminal to test but I cannot work that either.
