Description
[None]
The setting of this 8-position configuration DIP switch
determines the bus address of the ServSwitch Professor
and the CPU attached to it. Each of the switch positions
corresponds to a binary multiple—from left to right,
position values are 128, 64, 32, 16, 8, 4, 2, and 1—so
addresses from 0 to 255 are available. Because address 0
is reserved for diagnostics and address 255 is reserved
for the instructor’s System Control Module and CPU,
Student Modules and CPUs can be set to any address
from 1 to 254.
