IMPORTANT
The ASB module can be configured as any logical rack number
from 0 to 77 octal. Rack numbers are determined by setting
switches SW1-1 through SW1-6, with ON equivalent to logical 0
and OFF equivalent to logical 1. Then, interpret this 6-bit binary
value as octal with SW1-6 as the least significant bit (LSB). For
example:
SW1-1 SW1-2 SW1-3 SW1-4 SW1-5 SW1-6 Rack
