Working with GPS
Overview
The Dolphin 70e Black terminal contains an integrated GPS module that allows location tracking of
workers and vehicles, providing better utilization of field assets. Optional mapping and navigation
software provides turn-by-turn driving directions and location information.
Assisted GPS Support
Assisted GPS (A-GPS) is turned on by default. The Dolphin 70e Black utilizes gpsOneXTRA Assis-
tance™ Technology to improve time-to-first-fix (TTFF) positioning by using network resources for quicker
satellite identification. The carrier agnostic feature downloads a file (approximately 40KB) containing
emphersis data from a Qualcomm® server approximately every 7 days.
Note: A data connection is required and data transfer charges may apply depending on your carrier.
A-GPS can be turned off with the following registry key:
[HKEY_LOCAL_MACHINE\Software\Sierra Wireless Inc\swigobi\GPSSettings]
"GpsXtra"=dword:00000001
1 = enabled, 0 = disabled"
Powering the GPS Module
The GPS module powers on automatically when accessed by a software application and powers off
automatically when that software application closes. You cannot manually power on and off the GPS
module.
Communication Ports
There are two ways to access the GPS module: through the actual COM port (COM7) or the GPS Inter-
mediate Driver. The method you use depends on the software application you are using. If the software
application requires the actual COM Port, set the operating system to use COM7. If the software appli-
cation requires the GPS Intermediate Driver, set the operating system to use the GPS Intermediate
Driver.
Selecting the Port
1. Touch
> Settings
> System
> External GPS
.
2. In the GPS program port: drop-down list, select COM7 or GPD1 (the GPS Intermediate Driver) as
required by the application.
Note: The GPS program port and hardware port cannot be the same value.
3. Touch OK to save.
