User`s manual

In VXIbus systems with a V743 controller and a Agilent E1406A
Command Module, the V743 must function as the resource manager since
its logical address is fixed at 0. The V743 should be installed in slot 0 to
function as the system’s slot 0 device. The E1406A Command Module is
then a servant of the V743.
The resource manager and slot 0 functions, and the commander/servant
hierarchy concepts are covered in Appendix A "Terms and Definitions".
V743-2A : Setting
the Command
Module Logical
Address
Notice the following when setting the Command Module logical address.
• The V743 controller has a fixed logical address of 0 and a fixed
servant area of 255.
• The Command Module has a factory-set logical address of 0. Since
logical address 0 is the address of the resource manager (the V743),
you must change the Command Module’s logical address.
Recommended addresses are 1, 2, or 3, which are not instrument
identifier addresses (see Procedure 4: Configure and Install
Instruments). An address of 1, 2, or 3 also places the Command
Module in the servant area of the V743.
Set the logical address to 1, 2, or 3.
Logical address 0 is shown.
The logical address is the decimal sum of the
switches in the closed (1) position.
