3M M-Series GPS Receiver User Manual


 
Please refer to the section “3M
Dynatel Locator Setup” for more details on
how to setup the Locator.
Connect the Trimble GeoXT to the 3MDynatel M-series Locator using a
standard DB9 cable as provided with the 3M
Dynatel Locator.
Do not use the “null” modem adapter!
1. Open the GPS Connector application on the Trimble
GeoXT.
2. Turn on the 3MDynatel M-series Locator and go to the marker locate
mode. If the GPS unit is disconnected or has not acquired enough
satellites to give a position, the 3MDynatel Locator will display "Insert
External Device".
3. After the GPS unit has acquired a position, the 3MDynatel Locator
will display the latitude and longitude coordinates.
4. When a marker has been located and the GPS device has acquired a
position with adequate precision for your needs, press the Read key on
the 3MDynatel Locator.
When an iD marker is read, the marker data and GPS coordinates will be
displayed and saved to the Locator's memory. This data can be uploaded into
PC Locator tools and added to your database.
