serial error -1073807202 LabView 7.1 can't communicate with USB-serial adapter?

[j_eble]

Hello community,

I can't get LabView 7.1 to read data from the serial port. If I use the original examples, the examples given hier, VISA or not, I just get the error -1073807202 straight after the Configure vi.

Is it possible that LabView just can't communicate with Serial<->USB adapters?

The configuration should be correct: Everything is default, except for the baud rate. It is 38400 bps. Also, I *can* read characters via Win32 CreateFile() and friends. It also works with Hyperterminal. I use WinXP Pro if that matters. And yes, I use the correct COM port (COM4), I always verify that in the device manager.

Any help?

Best regards

Johannes

The error means that you don't have VISA installed. It's on the device drivers CD.

Hello Dennis,

thanks very much for your help.

Installing the VISA driver did the trick.
