VISA Instrument Not Recognized in LabVIEW

  • NI-VISA

Issue Details

I am trying to communicate with my 3rd party hardware with the VISA communication protocol in LabVIEW. When I try to select the VISA resource name on a VISA VI (such as VISA Open), I am not able to see the list of connected resources. However, I am able to see all my connected devices in NI-MAX and communicate with them.

Solution

Here are some possible workarounds to this issue:
  • Manually enter in the VISA resource name
    • The VISA resource name can be found in NI-MAX under Devices and Interfaces. Click on the 3rd party device and in VISA resource name will be located in the Settings tab
  • Programmatically retrieve the VISA resource in LabVIEW with the VISA Find Resource VI or with the VISA property node.
