  • Measurement and Automation Explorer (MAX)


  • NI-DAQmx

Issue Details

  • Opening NI Measurement & Automation Explorer (NI MAX) takes up to 15 minutes and does not let me communicate with my Ethernet cDAQ devices, losing connection intermittently.
  • Sometimes it also freezes the OS or parts of the GUI freeze or load for extended periods of time.



This problem could be related to a corruption of the NI MAX database or due to an incorrect installation of the DAQmx driver.
