Why do you need to know the address for the PCI-GPIB board?
There is no default hex address for any PCI board. Due to the plug-and-play nature of PCI, each card is given a base address by either the BIOS or the Operating System. However, if your system does not change, your hardware should be give the same address on subsequent reboots. Hoever, adding a new card or changing the slot of the card can often change the address that the board is assigned.
Also note that the PCI-GPIB board has two base addresses, pBAR0 and pBAR1.
If you are in Windows, you can determine the address of the PCI-GPIB board by looking in the device manager.
If you are using a different operating system, it likely provides a way to ascertain this information. For example, V
xWorks has a method pciDeviceShow to obtain the device number. You can pass the device number to pciHeaderShow to obtain the different base addresses.
