Urgent
I purchased three NI 9361 cards last year.
For one of the cards. I have everything unwired except a ground wired to COM to ground.
I have set all 8 channels to single ended with 5V pullup.
Here is what I get when I probe.
DI5+ / pin 14: Nothing
DI5- / pin 32: + 5V
DI4+ / pin 16: +5V
DI- / pin 35: Nothing
How am I getting this inconsistency? Could it be the Dsub or the NI Card? all measurements where with the oscilloscope referenced to the COM ground. Am I missing something in the documentation?
Let me know if you want any screenshots or documentation. Happy to provide anything.
