To install add-on modules, follow these steps:
1. Locate DIP switch SW3 at each add-on module;
set the DIP switch on each module as follows:
If the only add-on is Section 2 (32 ports total),
then set Switches 1 and 2 ON, with 3 and 4
OFF.
If you are adding Section 3 as well (48 ports
total), then you must also set the DIP switches
of Module 3: 1 and 3 should be set ON, with
2 and 4 OFF.
If you are adding Sections 2, 3, and 4 (64 ports
total), then you should retain the previous
configurations and also set the switches on
Module 4: 1 and 4 to ON, 2 and 3 to OFF.
2. Remove the top cover from the base unit.
3. Place the Section 2 add-on module over the
master unit. Position the add-on so the P1
and P2 connectors are accessible on the
master unit.
