Modem
The Modem connection uses the RS-232/RS-485 connection, but the converter now includes an external
modem (i.e. communication device) to plug into the communicate port of your host computer. A dedicated
internal modem can be used, which does not require a RS-232 connection, just a phone line connection. This
Data Link type is used for remote connections to and from the recorder(s) and meter(s). See the illustration
below.

Ethernet
The Ethernet (10-base-2 or 10-base-T) connection uses a 10-base-T or 10-base-2/RS-485 router (EKM-E) at
each location that is IP addressable .
