The VXIbus Chassis Resource Manager identifies modules in the
system by the module's address. VXIbus logical addresses can
range from 0 to 255, however, addresses 1 to 254 only are reserved
for VXIbus modules. Logical address 0 is reserved for the Resource
Manager. Logical address 255 permits the Resource Manager to
dynamically configure the module logical address.
To change the Model 3151/3151A s logical address, use the 8-
position DIP switch accessible from the top side of the module near
the rear end of the case (switch S1). Figure 2-1 shows the location
of the logical address switch. The switches are marked with numbers
1 to 8. The Model 3151/3151A uses binary values (2
the logical address using the active low address switch. A switch is
active when its arm is placed in the ON position.
