Interface Page

The Interface Page allows you to connect and use
devices such as computers and differential GPS (DGPS)
beacon receivers to the eTrex.
Input/Output Settings
The 'Interface' Settings Page allows you to use your
eTrex with external NMEA devices, DGPS beacon
receivers, a personal computer, etc. You can choose from
seven different input/output serial data formats, or none
at all. Below is a description of each format:
•GARMIN - the proprietary format used to
exchange waypoint, route, and track data with a
PC.
•GARMIN DGPS - Allows DGPS input using a
GARMIN beacon receiver and a standard RTCM
SC-104 format and DGPS tuning.
•NMEA OUT - supports the output of standard
NMEA 0183 version 2.0 data.
•TEXT OUT - allows simple ASCII text output of
location and velocity information, without any
input capabilities.
•RTCM IN - allows DGPS input using a standard
RTCM SC-104 format without any output capabilities.
•RTCM/NMEA- allows DGPS input using a
standard RTCM SC-104 format andsupports the
output of standard NMEA 0183 version 2.0 data.
•RTCM/TEXT- allows DGPS input using a standard
RTCM SC-104 format and simple ASCII text output
of location and velocity information.
