NOTE:

Default Switch

Settings = 0

Set switch SW2-3 to 0 if this rack will have a unique

address (not complemented). If this rack address is a

duplicate of another I/O block or chassis, set the switch to

1 for primary or 0 for complementary. Refer to Table 4.G

for the complementary I/O rack address.

Only block I/O modules with all inputs or all

outputs can use complementary I/O.

Series A block I/O modules do not support

complementary I/O. If using series A modules, set

this switch to 0.

ATTENTION: Cycle power to the module after setting the switches.
