Differential measurements with a DAQ-500 card

[Nicolas_l2001]

I can't put the differential measurement mode in the Measurement & Automation Explorer. I'm using a DAQ-500 card of NI. Is this because my card doesn't support such measurement mode? There are no jumpers on the card for such a configuration...

Some help on this topic would be useful.

Is this an old card? NI website yields no information when searched for
"DAQ-500". What does the manual say? Most likely the older AT cards may not
have software configurable analog input modes. Some PCI cards I know can be
configured by M & A Explorer for input modes.

Hello Nicolas,

Thank you for your question regarding a DAQ-500 card. It sounds like you're having problems getting the card to operate in differential mode. Is your device perhaps a PCMCIA DAQCard-500? If so you should be able to use four analog differential inputs. Where is the problem occurring in MAX? Can you right click on the DAQCard-500 in Traditional DAQ Devices >> properties >> AI and then go to mode and select Differential there? If the device is indeed the DAQCard-500 shown here and the problem hasn�t been solved you may want to try to reinstall the card.

Other resources can be found on the ni.com website by clicking the support tab at the top of the home page. Then search from Technical
Resources at the top of the page for your topic. I hope these resources help! Let me know if you need any other support with this issue.
