Installation
Preparation for
Use
Preparation for use includes selecting the required logical address,
configuring the
Local Bus (if required),
and installing the module in a
VXIbus chassis.
Logical Address
Selection
The VXIbus Chassis Resource Manager identifies a module in the
system by the module’s address. VXIbus logical addresses
can
range
from 0 to 255
. However, logical addre
ss 0 is reserved for the
Resource Manager.
A
ddresses 1 to 254 are reserved for VXIbus
modules. Logical address 255 permits the Resource Manager to
dynamically configure the module logical address.
To change the 3152
B logical address, use the 8-segment DIP
switch
(S1) accessible from the side of the module near the rear of the case.
Figure
2-1 shows the logical address switch. The switch segments
are
marked with numbers 1 to 8. Each switch segment represents a
binary digit of the 8
-bit binary logical address
. The segment marked
“1” represents the least
-significant digit. A switch is active
(equal to 1)
when it is
moved downward to the “ON” position.
Astronics Test Systems
ships the 3152B with the logical address
set
to 2 as shown in Figure
2-1.
