5.7 Working with GPS

Tap > Settings > System > System Information > Wireless to see if

your device has GPS installed. COM2 is the dedicated hardware port for

the built-in GPS (COM1 is dedicated to the external 9-pin).

The GPS is compatible with applications that accept the NMEA position

information using a default baud rate of 38400.

GPS settings:

If you are using only one GPS-aware application, these settings do not

need to be changed. However, to use multiple GPS-aware applications, tap

> Settings > System > GPS and select the following tabs:

 Access: The GPS Intermediate Driver (GPSID) allows

multiple applications to access the GPS receiver. If the check

box is unchecked, the GPSID is disabled.

 Hardware: COM2 is the hardware port dedicated for the

built-in GPS. Verify that COM2 is selected. The internal GPS

communicates at 38400 baud by default. If it has been

modified by a third-party program, adjust to match the

receiver baud rate.

 Programs: Programs that use GPS need to know which COM

port to use to access GPS data. When using more than one

GPS-aware application, the same GPSID port must be used

in each application. Ensure that the COM port on the

GPS-aware application(s) is set to the same GPSID port as

shown in the Programs tab of the GPS applet. The program

port must be a different port than the hardware port. By

default, the GPS program port is COM3 and should not be

modified unless directed by Technical Support.

NOTE: Some GPS-aware applications may not communicate over GPS

program ports.

Exiting GPS applications

Any time you exit a GPS application (such as SatViewer) it is advisable to

close the port gracefully, e.g. tap Disconnect from GPS and then exit the
