    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.

    Refer to Chapter 4: IEEE 1394 Fundamentals and Interface Overview for information on the topology and terms associated with the IEEE 1394 bus. Certain applications may include the HP E1406A Command Module as an HP-IB interface to selected instruments. In this configuration, the E8491A must be the resource manager since its logical address is always 0.
