The MAX VISA Timeout error is a general error that is thrown when MAX makes a VISA call, but does not get a response from the driver. Follow the steps below to resolve the error.
  • Reset the MAX Configuration Database to remove saved devices.
  1. Back up the configuration file if you have custom channels, tasks, or other settings you would like to save. 
  2. Reset the database file.
  • Make sure you have the latest compatible version of software installed.
