Chapter 3 VXI-MXI-2 Configuration and Installation

VXI-MXI-2 User Manual 3-4 © National Instruments Corporation

You can change the logical address of the VXI-MXI-2 by changing the

setting of the 8-bit DIP switch labeled LOGICAL ADDRESS SWITCH

(location designator U43) on the panel. The down position of the DIP

switch corresponds to a logic value of 0 and the up position

corresponds to a logic value of 1. Verify that the VXI-MXI-2 does not

have the same logical address as any other statically configured

VXIbus device in your system. Remember that logical addresses hex 0

and FF are not allowed for the VXI-MXI-2. Also, when setting logical

addresses, keep in mind the grouping requirements set by the system

hierarchy. See Chapter 6, System Configuration, or VXI-6, VXIbus

Mainframe Extender Specification, for more information on setting

logical addresses on a multimainframe hierarchy.

Figure 3-2 shows switch settings for logical address hex 1 and C0.
