Visa Address Problem

[J3000]

I have a Newport laser driver 8000.

In Measurement and Automation, this device reponded to "IDN?" query correctly.

But in Labview, when I use a visa resource name, I could not see the pull down menu that includes this device. In fact, the pull down menu is not active, I could not see COM1, COM2, either. If I run the device driver, I got an error message 1073807202.

Is there any way to add this device to the visa resource pull down menu?

Thank you very much.

If you install VISA, then everything will work just fine. The error code means "A code library required by VISA could not be located or loaded.". When MAX does the *IDN? query, it does not use VISA. It uses an ibwrt and ibrd (GPIB functions).

A newport library is available on the NI website, but this is not a good design, with too many sequence frames.

I'm trying to update a subset for temp and power control.

If you need a simple example , ask for it. But first install VISA, although it is not needed for this driver.

Thank you very much for the reply.

But how to install VISA? Does it come with Labview?

[Albert.Geven]

VISA is part of the intrument driver installation disks that come with labview.
If you installed labview and the instruments it should be there,

For gpib you can start MAX (Measurement and Automation eXplorer from NI and test the interface
You also can scan for instruments in Max
