130 Register-Based Programming
A16 Address Space
Outside the Command
Module
When the Agilent E1406A Command Module is not part of your VXIbus
system (Figure B-1), the multiplexer's base address is computed as:
1
C000
h
+ (LADDR * 64)
h
or (decimal)
49,152 + (LADDR * 64)
where C000
h
(49,152) is the starting location of the register addresses,
LADDR is the multiplexer's logical address, and 64
10
is the number of
address bytes per VXI device. For example, the multiplexer's factory set
logical address is 112 (70
h
). If this address is not changed, the multiplexer
will have a base address of:
C000
h
+ (112 * 64)
h
= C000
h
+ 1C00
h
= DC00
h
or (decimal)
49,152 + (112 * 64) = 49,152 + 7168 = 56,320
