NI-XNET Module Not Detected in MAX

Issue Details

• I have a C-Series NI-XNET module in a cDAQ/cRIO chassis. Previously, it was detected in NI Measurement and Automation Explorer (MAX). Now, it does not appear in MAX, although my NI-DAQmx modules are detected. How can I fix this?
• I am receiving error -88705 in MAX when using my XNET card 
• I can not see my NI FlexRay and NI CAN cards in MAX

Solution

NI FlexRay and CAN cards require the NI-XNET driver to function properly.

Troubleshooting steps vary depending on whether you're working with a Windows or Real-Time (RT) target, so please refer to the appropriate points accordingly.

• Ensure that you have a version of NI-XNET installed that supports your hardware (check the Readme).

• If you cannot see it, install the XNET driver from the NI website
• Check the driver version installed is compatible with your version of LabVIEW 
• If you have already installed the driver, try uninstalling and reinstalling it, then restart MAX

• If you're using an NI-XNET module, try installing it in a different slot within the chassis to rule out slot-related issues.
• Re-install the NI-XNET driver, or upgrade and make sure the version still supports your LabVIEW version.
  • If you upgrade the NI-XNET driver and the module appears, you may need to update the firmware of the module. You can accomplish this in MAX, by selecting your module and pressing Update Firmware.
• Disable the firewall or any software that could be preventing network communication.
• Try connecting different PC. If the other PC can detect the hardware, you may have to clean install Windows OS in your first PC or compare Windows registry entries to find difference.
• If the module still does not appear, reset the MAX database.
