Issue Details

When I attempt to run a Self-Test on my NI-XNET device in NI Measurement & Automation Explorer (NI MAX), the Self-Test fails even though the device appears in NI MAX.

 

I receive the following error:

 

The self test failed.

NI-XNET (Hex 0xBFF63005) Board self test failed(code 5). Solution: Try reinstalling the driver or switching the slot(s) of the board(s). If the error persists, contact National Instruments.

 

 

Solution

This error can be caused by either software or hardware issues. Try the following troubleshooting steps:

 

  • Reset the device in NI MAX and run the Self-Test again.
  • Re-register your NI-XNET aliases in NI-XNET Database Editor by deleting and re-importing the associated DBC or XML file.
  • Reboot the PC or PXI controller.
  • Remove and reinstall the device.
  • Try a different PCI/PXI slot or USB port, depending on your hardware.
  • Update NI-XNET to a version supported by your operating system and application development environment.
  • Temporarily disable any antivirus, endpoint protection, or security monitoring software and run the Self-Test again.
    • If the Self-Test succeeds when security software is disabled, work with your IT department to review the configuration of the security software and add any necessary exclusions for NI software.

 

If the device continues to fail Self-Test after completing the troubleshooting steps above, contact NI Technical Support.
