no visa resource found - cRIO

For now, I am more worried about the IO boards. Do you know why the IO boards are missing in MAX?

Thanks.

Hi JianZ,

If you are using a Real-Time operating system on the controller, then the modules will usually not be shown in MAX (CAN ports will generally show after the drivers have been loaded). Can you open a project and find the device and the modules? I am guessing that the error you are seeing may be related to the COM or USB ports as those are not shown. Typically in these scenarios I recommend the following troubleshooting steps:

1. Power down the device
2. Re-seat all modules (disconnect any external interfaces for troubleshooting)
3. Reset MAX configuration (Tools»Reset Configuration Data)
4. Turn the device on and reformat and reinstall the drivers/software (perhaps selecting all the install options for troubleshooting to ensure that you are not missing any drivers)
