The pop up menu of “VISA resource name” comes nothing except refresh.

I do not know why, I try to enable Termination Character, but when I reopen MAX, I find the software cancel this automatically.

Notes: No matter I set the "chosen VISA" as "Agilent VISA" or "Natinal Instruments VISA", it doesn't work.

How does the device show up in Windows Device Manager? A screenshot of Device Manager would be nice.

Now, in Lab view, I can use string to find my equipment, but can not find it through VISA find resource.

 

Work.

So if you use a string constant in the example it does not work?

I now change the resource name to GPIB19::10::INSTR, and replace the VISA IO control with a simple string constant containing "GPIB19::10::INSTR".

And it works now. But "VISA resource name" still can not find it.

Do you have any suggestions on that?

 

Thanks.

If you right click on the VISA resource name on the front panel and select I/O Name Filtering it will open the Filter VISA Names property dialog. I know that we have already looked at this, but have you tried setting the drop down below "Include these aliases" to "All defined aliases for all resource classes"? If not give this a try.

You may want to look at the following documentation. Specially tip 2.

You also might try force reinstalling NI 488.

I've noticed that some instruments only show up in the "VISA Resource name" property node if a VISA alias has been explicitly set for them in MAX.

So, try to select the "VISA Properties" tab for your device in MAX, type something in the "VISA Alias on My System" textbox and hit "Save".
