If you are installing the IEEE 1394 interface for the first time:
Continue with "Step 2: Installing the HP E8491B Interconnect."
•
If the E8491B and your VXI instruments are already installed:
Proceed to "Step 4: Installing the HP I/O Libraries." Note that the
HP I/O Libraries contain the OHCI-compatible host adapter drivers.
Note
Refer to Chapter 4: IEEE 1394 Fundamentals and Interface Overview for
more information on the OHCI-compatible PCI-to-IEEE 1394 host adapter.
The HP E8491B interconnect links the IEEE 1394 bus to the backplane of
the VXI mainframe. The HP E8491B is a C-size device with VXI Resource
Manager and Slot 0 capability.
There are no configuration switches on the HP E8491B. 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 HP E8491B is normally, but not required to be,
installed in mainframe slot 0.
Note
Refer to "Alternate Configurations" on page
the HP E8491B with the HP E1406 Command Module and using it in
VXI-MXI systems.
