5.4.3 Wiring
IL4-RD can be connected to any InteliLite 4 family controller via an onboard RS485 communication port or via
the external RS232/RS485communication ports on CM-RS232-485 communication module . It is possible to
connect up to three Remote displays to one Master controller, but each one needs to be using different
communication interface.. Connecting two or more remote displays to one communication line (e.g. RS485) is
not possible. Using one Remote display it is possible to monitor only one Master controller at the time.
Note:
IL4 AMF8 and AMF9 do not have an onboard RS485 comm port.
5.4.4 Interconnection variants
RS232
It is necessary to use CM-RS232-485 communication module on both the Master controller and the 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 wire (TxD, RxD, GND)
RS-232 connection is sufficient for communication.
RS485
Any combination of internal RS485 port or external one on CM-RS232-485 communication module can be
used for the Master and Remote Displays.
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
