Issue Details

I am trying to Self-Test my DAQ device on NI Measurement & Automation Explorer, which throws the following error:

Error -XXXXXX occurred at an unidentified location
Possible reason(s):
Internal Software Error occurred in MIO software. Please contact National Instruments Support.

The following error codes may occur with this message: -224603, -224609, -223750, -225202, -225203.



  • Power-cycle your hardware and computers. This issue has been reported to fix with a reset of the devices after a DAQmx update.
  • Remove all the modules from the cDAQ, and inspect connectors for any bent or broken pins. If there are bent pins, attempt to move them as straight as possible even if you are not using that slot. Reseat cDAQ modules and make sure it is not bending any pins.
  • Backup your MAX configuration data and reset the MAX database , then retry a self-test of the device.
  • Upgrade or reinstall your DAQmx driver.  If the data acquisition or signal conditioning cards that are giving the error are located in a remote system, ensure that the appropriate drivers are added to the remote controller as well.  It is possible that your driver has become corrupted and either a fresh install or upgrading the driver should resolve the issue.
  • Some USB DAQ devices might produce an error -224609 when used with a USB hub on a Windows 10 computer. In that case, you should plug your USB DAQ device directly into the computer without going through an external USB hub.
