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 3M™ Dynatel™ 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).
