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.
