VISA: (Hex 0xBFFF0015)

I asked about the VISA wizard, because I was getting it confused with another commenter had posted online, it could be completely be irrelevant. The unit is a Bertan 225 Series. It has a GPIB I/O, I'm using a GPIB to GPIB-USB-HS interface. Based on the fact that the above screenshots show that GPIB is recognized on the macine, I think the driver is installed.

It's not irrelevant if you actually used the wizard and from the MAX screenshot, it looks like you did. I'll repeat, the controller should not be appearing as a RAW resource. It does that when you use the wizard.

Haha No I didn't make anything up ... I have the GPIB driver installed, I'm still getting the same issue

[Dennis_Knutson]

Show your latest image from MAX, please. Exactly what version of NI-488 did you install? What does Windows device manager say? What new command did you try to send to the instrument?

[AndreaD]

I've decided to give another power supply a try, something much more modern ... I seem to be getitng the same error message, even with another unit. The unit I am currently trying is Keystone E3631A, which is a much newer unit. I have the latest NI-488.2 driver installed, and it uses SCPI

[Dennis_Knutson]

What you have makes no sense. If the driver is correctly installed, it would not be a USB RAW device. Nor would writing the id query to it be correct. You write to the instrument address. The instrument should also appear in MAX and it doesn't. Did you look at Windows device manager like I suggested? Why can't you provide that information? Why can't you provide the exact version of NI-488 like I asked for? It's the USB-GPIB controller actually from NI?

[AndreaD]

Version 15 ... Yep it's NI

[Dennis_Knutson]

I'm going away. I've asked you a couple of times to provide the Windows device manager information. No response from you. No explanation as to why you are writing to the controller, either. Good luck.
