Issue Details

  • In NI Measurement and Automation Explorer (NI MAX), I can see the modules inside my chassis, but I can't see the chassis itself.
  • When I plugged my chassis into my computer, it appeared for a moment in NI MAX and then disappeared.

Why can't I see the chassis, and how can I fix this so that I can permanently see the chassis and modules?


This behavior can happen if the NI MAX database has become corrupted. Follow the steps outlined in How to Fix or Reset the NI Measurement and Automation Explorer Database File to reset the database.
