GPS Tab
Connect to GPS / Disconnect
from GPS: This button either
tries to establish a connection
with the GPS receiver chip or
disconnects the connection.
COM: used to select the COM
port for communication
between SatViewer and your
GPS receiver. Your GPS receiver port is set to COM2 and a baud rate
of 9600. The default SatViewer settings shouldn’t need to be changed
to connect.
NOTE: Before changing COM port or baud rate settings, you must
first disconnect from your GPS receiver before making the changes.
After you have changed the COM settings, then you can re-attempt to
connect to your GPS receiver, using the Connect to GPS button.
When exiting SatViewer (or any other GPS application) it is good
practice to tap Disconnect from GPS before closing the application
to ensure the COM port is closed.
Enabling the Microsoft GPS driver
If you would like to connect two or more programs to your GPS
receiver at the same time (such as SatViewer and a navigation
program), ensure the Microsoft GPS driver is turned on:
1. Tap Settings / System / GPS.
2. Tap the Access tab.
3. Ensure there is a checkbox next to Manage GPS
automatically. This turns on the Microsoft GPS driver. Ensure
that the GPS program port is COM3 (or any other port
available in the Microsoft GPS driver screen) and the GPS
hardware port is COM2 with baud rate of 9600.
4. The Microsoft GPS driver will now allow multiple applications
to connect to your unit’s GPS receiver at the same time. Your
unit’s GPS receiver can be controlled with SatViewer while
other applications are also using your unit’s GPS receiver.
5. In SatViewer and any other program using your unit’s GPS
receiver, change the COM port to COM3 (or the COM port
specified in Step 3 above). Both applications will connect to
your unit’s GPS receiver through the Microsoft GPS driver.
