The Locator supports three modes – NMEA, GIS, PDA. The mode can be set
from within the Locator menu. Please refer to the section named “Dynatel setup”.
Mode 1 Operation – NMEA mode
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. When an iD marker is read, the GPS data is stored with
the marker's data in the Read or Program History memory on the 3M™
Dynatel™ Locator. All of this data can be uploaded into the 3M™ Dynatel™ PC
Locator Tools and can be stored in your database.
Mode 2 Operation – GIS mode
In the GIS mode, the Locator sends out the iD marker record template data to the
external device through the serial port, there by allowing different GIS mapping
capabilities.

The data that is sent out from the Locator can be used to interface to a custom
application on a smart GPS/GIS device to attach the data to the GPS Log point.
This information is in standard GIS shape file format.
