Hi,
I have some questions:
What OS are you using?
What driver versions?. You can find the driver versions in the Windows Add/Remove programs utility. DAQ driver is NI-DAQ anmd GPIB driver is NI-488.2.
Is there any error code?
I haven't found any known issues between these two drivers. How are the board's resources configured? Base address, IRQ, DMA.
Let see if with this information we can clear out what is going on.
