PCI-6220 analog input not functioning

[mcdonals]

Hello,

The company I work for has a PCI-6220 DAQ card connected to a probe reading voltage values. I have written software in labview to read data from the probe as well as to adjust the gain using digital inputs on the probe. The software for adjusting the gain works fine, but the analog inputs all read a constant value of 10.6. The same software communicates flawlessly with the same probe when connected through a 6229 DAQ card we have in a different computer, which has led me to believe there is a problem with our 6220 DAQ card. The card passes the self test in the measurement and automation explorer, but fails the self calibration. Also, the test panels in the measurement and automation explorer read a constant 10.6 as well. What might the problem be?

Thank you for your time

Hi mcdonals,

You should check to verify that you have the same DAQmx driver installed on both computers that you are comparing to be sure that the issue is not with your driver. You can try the newest DAQmx driver which is available for download at a link below. I have included a link to our DAQ Diagnostic Utility that you can download and run to test out your boards functionality. You will be able to print a diagnostic report after the test runs and this will provide a more detailed analysis of the problem.

Hello Mcdonals,

Have you solved this problem? I am currently having the same problem with my PCI 6221 and can not solve it. I always get -10.6V or +10.6 as analog input voltage whatever the input is. I need your feedback on this. Could you please tell me what you have done to solve the problem?

Thanks.
