5.4.4 Interconnection variants
RS232
It is necessary to use CM-RS232-485 communication module on both Master controller and Remote display.
COM 1 communication channel is used with these settings:
COM 1 Mode: Direct
COM 1 Communication Speed: 57600 or 115200 bps
Controller Address: 1 – 32
The maximal distance between Master controller and Remote display is 10 m for RS-232 connection. It is
recommended to use standard Null modem cable (crossover cable), although three wires (TxD, RxD, GND)
RS-232 connection is enough for communication.
RS485
It is necessary to use CM-RS232-485 communication module on both Master controller and Remote display.
COM 2 communication channel is used with these settings:
COM 2 Mode: Direct
COM 2 Communication Speed: 57600 or 115200 bps
Controller Address: 1 – 32
The maximal distance between Master controller and Remote display is 1200 m for RS-485 connection. It is
recommended to use shielded twisted-pair cables that comply with the EIA RS-485 standard to reduce
interference and to achieve maximal distance.
