Lan + Serial CM02A
Quick Information
The Brodersen LB2 communication modules can be used with the RTU32M series products. The comms modules are in two parts, a bottom part containing the backplane bus, and a top part containing the comms board and interfaces.

The Brodersen LB2 communication modules can be used with the RTU32M series products. The comms modules are in two parts, a bottom part containing the backplane bus, and a top part containing the comms board and interfaces. All LB2 comms modules are hot-pluggable. The CM02A is a 2-port communication module with 1x 10/100 LAN port and 1x Isolated RS232/RS485 port that is ‘plug and play’.
The module is self-configuring and is managed via the RTU web server. The SP04A module is used to connect legacy serial equipment to your infrastructure using serial protocols that include DNP3, IEC 60870, Modbus, Omron, and DF1.
- 1x Isolated RS232/RS485, configurable with 3x dipswitches
- Configurable FULL/HALF Duplex and Configurable Endtermination on RS-485
- 1x Isolated LAN 10/100
- Maximum 3 x CM02 in a configuration
The CM02A serial communication module provides the following communication ports: COM1: Isolated RS232/RS485, configurable (with 3x dipswitches), with RJ 12 (6P6C).
For configuring COM port, dip-switches are used:
It should be mentioned that the dip-switch for enabling/disabling the termination resistor (DSW-3) is just functional in RS485 mode. In RS232 mode, the termination resistor is always disabled.
