You should use Other for your GPS receiver.

No predefined initialization command is send to the receiver.

If the Earthmate outputs standard NMEA messages, the baud rate should be 4800.

To view the data from the GPS receiver open the NMEA Display window using the
View / View Messages menu items.
For WinPlotGPS to work with the Earthmate receiver, the receiver must output
the follow NMEA messages $GPRMC, $GPGGA, $GPGSA and $GPGSV.
In the message viewer window you should see GPS messages like this:
Hope this helps. Let me know if you get it working,
