Selecting the DNP3 protocol on the Ethernet port launches the

DNP3/TCP server along with the Modbus/TCP server allowing
simultaneous connections on both TCP ports. Selecting the Modbus

protocol for the port disables the DNP3/TCP server.

The meter automatically detects a replaceable communication module

and does not allow you to change the interface, baud rate or data
format for the Dial-up modem, and for the Ethernet port.
