Labview GPIB connection.

[ninskaya]

Hi, I would like to open a Labview window to see data from a scope (Scope Explorer) through GPIB. I have been using the attached vi which then gives me an "old VISA open" error message. Do I have to open a special VISA connection?

Thanks,
Ninskaya

Hello Ninskaya,

Thank you for contacting National Instruments.

I am not seeing your attached VI. If you still need help with this issue, let me know. Try reposting the VI you are using, and if possible, provide a little information about the specific instrument you are trying to communicate with.

Hi Matthew, thank you for replying. I forgot to attach the vi. Actually, I have another question. I'm not able to make a GPIB connection because the driver hasn't been well installed. I would like to uninstall it in order to reinstall it properly, but there no such option on the CD rom. How could I do that?

Thanks a lot,
Ninskaya

Hi Ninskaya,

I am assuming that the GPIB driver you are referring to is the NI-488.2 driver. If this is the case, then first try going to Add-Remove programs in Control Panel. Look for NI-488.2, possibly under NI Software. You should be able to remove the NI-488.2 driver.

If this does not work and you are still having problems, let me know.
