INSTALLING THE GC CONTROLLER

3.4.1

Modbus Slave Address (COM ID) Setup

The GC Controller's COM ID is determined by dual inline package (DIP) switch settings. In
most cases, the COM ID setup made at the factory will not require changes. (Unless
otherwise specified by the customer, the DIP switch settings made at the factory give the
Controller a COM ID of 1 (one)).
This section applies only to GC systems which have not been shipped "prewired" or may not
have had the COM ID set according to customer specifications.
Follow the steps in this section only if you wish to do the following:
(1) Change the GC Controller's COM ID, or
(2) Visually inspect and verify the COM ID as determined by the DIP switch settings.
