PCI-MIO-16E-4 connected to SCXI-1102 bad data

[dan.dye]

Hi

I have a PCI-MIO-16E-4 card connected to an SCXI mainframe, which has the SCXI 1102 32-Channel TC Amplifier plugged into it, which has a 1303 terminal block connected to it.  It has worked well for years, but quit working last week, possibly after a power surge.  However the PC and all DAQ hardware is connected to a UPS.  Anyway, NI Measurement and Automation Explorer can see the chassis, PCI card, and module just fine, but when I test the TC channel I get a bad signal, either a negative signal, very high signal, or no signal at all.  I've tried swapping the module for a different one, changing channels on the terminal block, changing the thermocouple, tested the fuse, visually inspected all terminals and connections, moved the PCI card to another slot on the motherboard, etc...  I was acquiring signal from about 8 different channels before it happened, and after it quit working none of them would test properly, so I stripped it down to just a single channel and single module in the terminal block. 

I'm at a loss here.  I think that the hardware may be physically damaged, but I'm not sure how to test it.  I ran the test on the PCI card in MAX and it seemed like it tested out just fine, but perhaps there are more diagnostic tests I could run.

Thanks for your help!

Hello Dan,

When you did the testing of the thermocouple channels, did you use tasks in MAX that were already existing, or did you use entirely new thermocouple tasks?  If you used tasks that were already existing, I recommend setting up new tasks. Another thing to try is running the DAQ Diagnostic Utility on your PCI-MIO-16E-4 card.  This will help determine if the DAQ board itself is the problem.

Best wishes,
