114 HP E1563A and E1564A Register-Based Programming
When the HP E1406A Command Module is not part of your VXIbus system
(Figure B-2), the digitizer's base address is computed as:
C000 + (LADDR * 64)
16
or
49,152 + (LADDR * 64)
where C000 (49,152) is the starting location of the register addresses,
16
LADDR is the digitizer's logical address, and 64
bytes per VXI device. For example, the digitizer's factory set logical address
is 40 (28 ). If this address is not changed, the digitizer will have a base
16
address of:
C000 + (40 * 64)
16
or (decimal)
49,152 + (40 * 64) = 49,152 + 2560 = 51,712
