Hi ljamyl,

Looks to me like the visa resource is busy. Being used by some other part of the program, or perhaps still used in max?

Regards

Is the Console Out Enabled in MAX? That could be holding the Port. You could try configuring it for the second port.

In Max,when I point "open the VISA test panel",the same error display,so I think maybe the port is close, but how can I open the port?

lijamy,

The Console is enabled/disabled in MAX on the Settings for the cRIO....it is not a property of the VISA settings for the SOM COM Ports.

You must reboot the SOM to set the console configuration. The console is to debug to system and is not needed for normal SOM use.

I've been working on several SOM projects and have had no issues with serial port. You do need the ASRL:: syntax, "COM1", etc does not see to work witht the SOM.

Regards and Good Luck
