4.
A shunt is provided to disable a maximum of
two unused modules in Class B operation and
Class A operation. Modules are disabled from
the highest address and work downward. If
two modules are disabled, the lowest four ad-
dresses will be functional, while the highest
two will be disabled. For example, in Class B
operation, if the shunt for Address Disable is
placed on "two" and the base switch is set to 28,
the modules will be assigned to 28, 29, 30 and 31 while disabling the
highest two positions.
NOTE: Place unused shunts on single pin to store on board for future use.
NOTE: Power must not be applied to the unit when changing functionality of
the shunts.
