Error code -1073807343

[geraldW]

Hello,

I am using the serial port of my PC with LabView. I started from the VI Basic Serial Write and Read, but now I get the error -1073807343, for which I can't find an explanation. The error occurs in the VISA: Configure Serial Port-vi. It also occurs if I use the original example Basic Serial Write and Read.vi.
What can be the reason for this and what can I do?

Kind regards,

Gerald

Another error code I get is: -1073807246.
I hope this has nothing to do with my LabView-Version. I am using LabView 8.2, Evaluation Version.

Regards, Gerald

I suggest you to use the Help->Explain Error menu item to get more information. One of those error means that you specified something incorrect for the resource name (probably the resource does not exist), the other that the resource does exist but cannot be accessed (probably because it is already opened by some other process)

I don't get any information about this errors in the Help.
It says: The error code is not defined. Why is that?

Did you install VISA on your computer from the NI Device Drivers Cd?

[geraldW]

No, I have only a LabView Evaluation Version and no Device Drivers CD.
This might be the reason.

Yes, it is. But you can download VISA from the NI site.
