PCI-GPIB card cannot find instruments in Windows 7

[Yu-tong]

hello, i am new to use Labview to control lab equipments. would be very appreciated any help in advance. Here is my case.

We have two NI PCI-GPIB card in lab. They are working well in old PCs with Windows XP. I installed them to new PC with Windows 7 enterprize edition. Labview version is 2014. The NI-488.2 14.0 and Ni-VISA 14.0.1 is also installed. 

when running NI MAX, i could see PCI-GPIB card, so far everthing is fine, no error code. But when i click scan for instruments. there is no result, also no error code message. I borrowed a GPIB-USB-HS controller from another lab. It woks well with the same GPIB cable and equipment. i could see the equipment and communicate. i tried both our PCI-GPIB card and got the same result.

Does someone happen to see the similar problem?

Thank you.

If you move one back to the old pc, does it still work? Are you putting both into the new pc or just one? I would try one at a time before installing both of them.

Hi thanks for looking into my problem. here is some update.

first, i installed the PCI card to the new PC, it does not work as described above. then, i took it from the PC and installed the GPIB-USB-HS controller. It works well to find our equipment and everything is fine.

second, the oringinal old pc with this PCI card is down, so i used another old pc. this makes problems more complicated. i installed the PCI card on the old PC and it not work. then I connected the USB controller, it works fine. same problem as the new PC.

third, i tried both PCI card. they have the same problem. i think it is unlikely these two cards are both damaged.

I also followed instruction from  KnowledgeBase 1UO68A5P: "Scan for Instruments" Fails in Measurement & Automation Explorer. does not improved. the settings of PCI card is shown as attached.

thank you.

some update on my problem.

i tried another old pc, the same model. i find the PCI card works on this one. so the answer is yes it works when put it back to the old pc. the USB controller also works on old pc.

Now i am back to the starting point. My PCI-GPIB card works on a old lab PC, but nor works on a new PC. Would it be possible that it may not working compatible with newer computer, even if the card there is no error message?

Umm, interesting the png does show me there is an error. Have you figured out what error it is?

Your issue seems like something incompatible -- driver/OS/Hardware -- what I am supposed to do is to uninstall NI-VISA and try another version.

But before that, try MAX --> TOOLS --> NI VISA --> VISA OPTIONS, in the right pannel, My system --> General Settings --> Passports, tick NiVISATulib.dll.

This usually works if you are using a non-NI card, but worth to give it a shot. 🙂

good luck.
