NI USB-GPIB-HS error

[Mihael]

Hello everybody!

if this question has allready been answered; forgive me, but I wasn't able to find it (and I really tried).

I'm using a NI USB-GPIB-HS cable to communicate with a Keithley 2000 multimeter (with a SCAN multichannel card), and Labview 8.0. The program I wrote read resistance on different channels. As I was testing it, at a certain point I ran the program with Keitley turned OFF. A lot of erros prompted the screen and I aborted the program. Then I turned Keithley on again and ran the program, but whatever I do, I keep getting a NI 488.2 error: 'No board present' on the screen.

I've restarted the computer, and Keithley -> didn't work.

Reinstalled the drivers -> didn't work

Changed the GPIB adresses (both Keith and program) -> didn't work

Tried to see if the USB-GPIB-HS card has been damaged by running the Mesurement and control; Ni 488.2 analyzer , but it failed to detect it. However, this test isn't conclusive because I also ran it on the other computer where I have a GPIB-PCI card and it also didn't detect it.

Both LEDs ('ready' and 'active') od the USB-GPIB-HS cable are blinking (not at the same time..) during the test.

Also I've installed the 8.0 ->8.0.1 ->8.2.1. update, though my Labview says it's a 8.0.1 version. Is it possible that there is some kind of a bug with the update? (Though I don't believe that, cos the program ran smoothley with the updates before the program was ran with Keithley turned OFF..).

If somebody had a similar problem and solved it -> please let me know.

Thanks.

Mihael

I can't help you with the GPIB issues, but the 8.0.1 -> 8.2.1 isn't really an update per se - it installs the new 8.2.1 version in parallel with the 8.0.1 version, so there should be a new entry in your start menu - try that.

Hi crelf!

I've checked it, and there was no new entry. So I've tried to reinstall it; and was stopped just before I got to initiate the installation. It said "No software will be installed or removed." only >>Back<< key was enabled.

Ok; I tried my lab-neighbour's Keithly USB-GPIB anad everything worked fine. After (again!) reinstalling the NI USB-GPIB HS drivers (v2.5) everything is back to normal. The card works just fine.

Glad to hear you got it up and running
