Using an Unspecified GPS Device


Most GPS devices with a serial output can be configured to output the latitude
and longitude data according to the NMEA (National Marine Electronics
Association) standard. These devices can be used in the Mode 1 operation (See
3M Dynatel GPS Modes, Mode 1 NMEA

Operation).


However if the GPS device supports Arcpad application, 3M Arcpad
scripts can be used to interface with the Locator.

GPS Device Setup

Select NMEA and baud rate of 4800. On the Garmin eTrex, go to the Main
Menu. Select Setup, then Interface. Select NMEA In/NMEA Out (the Baud rate
is fixed to 4800).

NMEA Datum - This is the datum your GPS uses to output the position in the
NMEA data. Garmin will output the datum the GPS is set to. Other GPS output
in WGS 84. You need to find out how your particular GPS does this.

Using Trimble™ GeoXT™ with Terrasync™


Mode 2 (GIS) operation is not supported in the 3MDynatel Locator software
version 17 and newer versions. This section in this document refers to the older
versions of the software only.

The users are encouraged to use Trimble GeoXT with Arcpad scripts
provided by 3M. The scripts provide more efficient interface and run in
Arcpad application for data logging. Please refer to the section “Installing and
Running Arcpad scripts” for more details.

This device allows Mode 1 or Mode 2 operation (not simultaneously).
