Technical Manual
The two 2-wire ports are called COM1 and COM2. Alternatively, if there is only one
4-wire port configured, the port is called COM2. The fibre-optic ST connection uses the
COM1 port.
Table 552: EIA-485 connections for COMB01A-COMB014A
12.2.7.2
COMB023A jumper locations and connections
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 calIed.
COM1 and COM2. Alternatively, if only one 4-wire-port is configured, the port is called
COM2. The fibre-optic ST connection uses the COM1 port.
Table 553: Configuration options of the two independent communication ports
Termination is enabled at each end of the bus.
It is recommended to ground the signal directly to ground from one node
and through capacitor from other nodes.
Collision detection in serial communication is supported on 2-wire mode,
in the following cards/ports: COMB23A: COM1, COMB11-14A: COM2.
