Can't Change Serial Port Settings

Issue Details

My COM port shows up in MAX, but I can't use it. I get a warning that says "The VISA port settings are different from the Windows port settings. Select the settings you want to keep." If I select either setting, I get an error and am returned to the same screen. How do I move forward from here?

Solution

This may occur when the Windows COM port setting gets changed. If MAX cannot automatically fix the problem, you may be unable to use your hardware. To solve this, reset the max configuration.
