Hi Steve, Update, no mater what I put in slot 10 it doesn't work, I have used (6) different backplanes. I move my AI & AQ to slots (8) & (9), and a Discrete Mixed IO card to slot 10. The AI & AQ are working but the Mixed IO in slot 10 does not. I even backed up a project from a running machine and uploaded it to this machine and that didn't take care of it either. My next step is to pull the whole rack out of anther machine and see if it will work. Do you have any other ideas? Do you know how to test a backplane?
Thanks,
Donnie
