Hi, I'm having an issue getting my GPIB-USB-HS device to recognise instruments in LabVIEW. The device worked last year on many instruments. I've tried other GPIB-USB-HS devices too just to make sure it wasn't a faulty device. NOTE: I installed the latest drivers for NI-VISA 5.1.1 and NI-488.2 300 for Windows XP See the images below: This is the idsplay in MAX:I'm unsure why there is a yellow "!" next to GPIB0::INTFC, I'm thinking this is an indication of my issue. However, notice that instruments that my GPIB-USB-HS is connected to are recognised in MAX. As you will see LabVIEW 8.5 doesn't recognise them. I get this error warning in MAX when I try to open TOOLS>NI-VISA>VISA INTERACTIVE CONTROL: This is the image of my LabVIEW 8.5 window when I try to select a VISA of a connected instrument (one of which MAX recognises): Any help would be very much appreciated 🙂 Thank you, - Brian

Thank you all for your assistance, Problem Solved after hours of uninstalling and re-installing all National Instruments devices/software. Once all programs were uninstalled (with a disk cleanup on my harddrives- possibly unnecessary) LabVIEW 8.5.1 was re-installed NI-DAQ was re-installed NI-Visa 5.1.1 was re-installed NI-488.2 ver 2.7.3 was re-installed (properly) Now LabVIEW recognises all ports/devices and connects to instruments properly once again. My issue must have been installing LabVIEW 8.5.1 after already having installed LabVIEW 2009. Somewhere during the installation of 8.5.1 - the main post issue occured. Thanks again

GPIB-USB-HS will not recognise any instruments in LabVIEW but somewhat does in MAX - help

Solved!

MATLAB takes less than 20 minutes to install..

and is far superior to LabVIEW in many ways *cough*
