Two PCI-GPIB-300K on one PC?

[aps7828]

Greetings!

We are trying to use two PCI-GPIB-300K cards from Measurement Computing Corporation.  We began just using one GPIB card in the PC, installed the proper drivers and the card was found using NI VISA Interactive Control (VIC).  We have been running VI's on this machine, with one GPIB card, just fine for some time now.

Recently, we attempted to install a second GPIB card (same model) into the same PC.  We planned to use these two cards independantly, one GPIB card controlling 2 devices, the other GPIB card controlling 2 other devices, on 2 independant busses.  We see both interfaces in the Hardware Device Manager (Windows XP), and we can communicate with devices connected to either card using CBIC32 and sending commands to the devices' specific addresses.  However, when we open up VIC, only interface GPIB0 is shown, and interface GPIB1 is not.

We configured both cards the same way using CBCONF32: both are the System Controller, both have Primary Address 0, and both have "Disable Auto Serial Polling" set to NO.

Are we misunderstanding something, or doing something wrong?  Thanks in advance for your help!

Hey,
One Quick question can you see GPIB1 in measurement and automation explorer (MAX).

Well, we have not been using MAX because we had problems getting GPIB0 to show up there when we only had one PCI-GPIB card installed.  We were just using CBCONF32 and CBIC32 to configure and test our setup, and using Visa Interactive Control to make sure the card was recognized by LabVIEW (after installing the proper drivers, etc).

However, we tried an experiment; we installed two PCI-GPIB-300K cards into a different PC with an almost identical set-up, and sure enough both cards were recognized by VIC.  We must be having a driver issue or something else that we overlooked.  In any case, we know it can be done, it's just a matter of figuring out what our problem is on the specific PC we are trying to use.

Hey,
I would say talk to MCC because it looks like a card specific problem.
