The V743 Logical

Address and

Servant Area

The following pertains to the V743 logical address and servant area:

• The V743 controller has a logical address of 0 and a servant area of

255. These values are stored in software and cannot be changed.

• With a logical address of 0, the V743 is the VXI system’s resource

manager. It is recommended that the V743 be installed in mainframe

slot 0 so that it also functions as the system’s slot 0 device.

• With its logical address set at 0 and its servant area set at 255, the

V743 controller is the system’s top level commander. However, a

commander can be a servant to another commander thus forming a

hierarchial system. Servants in the servant area of the "lower-level"

commander are controlled by the lower-level commander.

• The V743 should be the commander of the system’s message-based

modules (including other commanders). This enables the

message-based modules to be programmed at higher speeds across

the VXIbus backplane. A commander such as the Agilent E1406A

Command Module should be the commander for the system’s

Agilent Technologies register-based modules. This enables the

the Command Module.

V743-2 : Set Up the Agilent E1406A Command Module

Note If an Agilent E1406A Command Module is part of your system, continue

with Step V743-2. Otherwise, proceed to step V743-3.

When an embedded controller such as the Agilent E1497A V743/64 or

Agilent E1498A V743/100 and a Agilent E1406A Command Module are

part of your VXIbus system, you must configure the Command Module for

use with the V743. This includes:

• setting the Command Module logical address so that it is a servant to

the V743

• setting the Command Module servant area so that it is the

commander of the system’s Agilent Technologies register-based

modules

• setting the Command Module primary GPIB address

• disabling the Command Module’s slot 0 and system controller

capability
