G.Replace the computer cover. Connect one end of the interface cable to either of the adapter’s external connectors. You can now turn on the PC.

Note When power is applied, Windows 95 operating systems may detect the

Adaptec® card and indicate that it cannot locate an associated .inf file. Ignore this message as the .inf file is installed when the HP I_O Libraries are installed (Step 4).

Step 2: Installing

the HP E8491A

Interconnect

Refer to Chapter 4: IEEE 1394 Fundamentals and Interface Overview for more information on the Adaptec® host adapter.

If you are installing the IEEE 1394 interface for the first time, continue with “Step 2: Installing the HP E8491A Interconnect.” If the E8491A and your VXI instruments are already installed, proceed to “Step 4: Installing the

HP I_O Libraries.” Notice that the HP I_O Libraries contain the Adaptec ® host adapter drivers.

The HP E8491A interconnect links the IEEE 1394 bus to the backplane of the VXI mainframe. The E8491A is a C-size device with VXI Resource Manager and Slot 0 capability.

There are no configuration switches on the E8491A. The device’s logical address is 0 and it provides the system’s resource manager functionality via software that is part of the HP I_O Libraries. Its VXI servant area is 255, therefore; it is the interface to all VXI devices with logical addresses between 1 and 255. The E8491A is normally, but not required to be, installed in mainframe slot 0.
