4�- OPERATION

The CEM M-ETH is designed to be used as a Ethernet port for any device in the CEM family,

using the mechanical coupling next to the optical port.

4.1.- OPERATING PRINCIPLE

The CEM M-ETH is an optional accessory for electrical energy meters from the CEM range

that are mounted on DIN rails.

The CEM M-ETH provides CEM units with Ethernet communications with the MODBUS/TCP

protocol.

Once the unit is coupled to the CEM energy meter (See “3.2.- INSTALLATION”) the LINK LED

turns green to let the user know that the link has been made correctly.

From this point onward, the new CEM energy meter + CEM M-ETH assembly functions as a

single device.

4.2.- LED INDICATORS

The unit has three indicator LEDs:
