CPU and COM4A Serial Communications Setups

The GC Controller has four serial communications channels: COM1, COM2, COM3, and COM4.
Through jumper settings, they can be configured for the following serial signal definitions: RS-232,
RS-422, or RS-485.
The serial signal definitions and the ports that support them are as follows:
RS-232
J5, J6, J10, and J11;
and DB-9 ports P2 and P3
RS-232
Com 5 = P22
Com 6 = P23
Com 7 = P24
The serial ports and terminals listed above are located on the GC Controller's Terminal Board for
Field Wiring (TB).
Serial ports configured for RS-232 are most commonly used for direct serial communication between
the Controller and a PC or modem.
