The optional communication module supports EIA-232/EIA-485 serial communication

(X6 connector), EIA-485 serial communication (X5 connector) and optical ST serial

communication (X12 connector).

Two independent communication ports are supported. The two 2-wire ports are called

COM1 and COM2. Alternatively, if only one 4-wire port is configured, the port is called

COM2. The fiber optic ST connection uses the COM1 port.
