PCI-GPIB communications problem

[Ashley.w]

I have a frustrating problem with my PCI- GPIB communications interface.   

I have a test rig with 4 PCI-GPIB-interfaced instruments.  They seem to be connected and communicating fine when I going into measurement and measurement explorer and call up devices.  That is I can send and ID query and the instruments send their identities back to the PC suggesting the hardware and software is correctly installed.  However, when I try to run the Lab-VIEW instrument drivers they I consisently get an error message coming up telling the device cannot be found, regardless of which instrument I try to run.  This is despite having the correct adresses set-up in the instrument resourse name box. 

Before converting to using a PCI-GPIB interface I had been using a USB/GPIB interface to connect to the PC and this worked OK reasonably well except that one of the instruments (a Keithly Picoammeter) didn't always connect (hence the change to a PCI-GPIB interface). 

Help would be greatly appreciated as I am totally stumped.

Thanks

Is your application designed so that you can unplug all but one of the PCI-GPIB controllers and test the instruments just connected to that PCI-GPIB? It may be easier to reduce your system to the minimum number of components in order to isolate the failing cases.

In the VISA resource name, did you type in the address or select one from the pull-down menu? The pull-down is accessed by clicking on the arrow on the right side of the control. Before you installed the PCI card, did you remove the USB card from the system? If you didn't, the PCI card may have been installed as GPIB1 instead of GPIB0. You might try going into Device Manager and seeing if there are multiple GPIB devices listed. If that's the case, uninstall all and remove the PCI board. Replace the PCI board and see if it installs as GPIB0.
