1 General
The CEC-DM1 is a converter module between the CAN bus and the Ethernet network.
It is used in the GMS measuring system for data exchange between the RMS/GMS units and the control
software in a Panel PC. The IP-based protocol uses the UDP transport layer for data exchange.
Each unit has a unique MAC-address and the configurable IP-address. The software in the Panel PC is set up
to exchange data to a specified IP-address.
The unit is powered with 24Vdc.
