turn to flash every 2 seconds and GPS Orange LED will be also On.
Note: Power saving mode would not function when USB is plugged
in.

6-4. Configure the GPS Intermediate Driver with the
GPS Settings icon
The GPS Intermediate Driver is a software layer between a Windows
Mobile application and the GPS hardware drivers. This allows
applications to work with a variety of GPS hardware. The GPS
Intermediate Driver uses the registry to determine what COM port
should be used to communicate with the GPS hardware. The
recommended way to configure the registry to work with your GPS
device is the GPS Settings icon
1. From the Start menu, click Settings. On the System tab, click the
External GPS icon. On some devices, this item has a different name.
2. On the Programs tab, select any
available COM port from the GPS
Program Port drop-down list. The GPS
data sent through the GPS Intermediate
Driver is streamed to applications
through this port. This should not be
the same port that your GPS receiver is
configured to use. If your application
can’t receive GPS data stream, leave
GPS Program Port for empty.
Applications will use GPS Hardware
Port as communication port.

6-6. Change fix update rate and Activate A-GPS by
QstarzGpsView software application
A-GPS is a system where outside sources, such as an assistance
server and reference network, help a GPS receiver boosts
performance beyond that of the same receiver in a stand-alone
mode by downloading the almanac data from an assistance server.
Note1: A-GPS can boost GPS warm start speed to always lower than
15sec fix after the first fix. The A-GPS efficiency will decrease
when time goes by. After it expires, you would have to
download almanac data again or delete it because the
acceleration efficiency of fix will become totally ineffective.
Note2: Please don’t update the almanac data by Bluetooth
interface.
Note3: Under 10Hz fix update rate, DGPS function will be disabled
1. Connect BT-Q818XT with your PC by mini-USB cable.
2. Switch BT-Q818XT on.
3. Execute QstarzGpsView.exe. (GPSView can be download from our

4. Select COM port (To find the valid com port, please go to <Device
Manager> and expand the <Ports (COM & LPT)> and check “GPS USB
Serial Interface Driver”) and set the baud rate to 115200.
5. Click On button to establish the communication between
BT-Q818XT and your PC. If the connection is successful, the NMEA
stream will keep showing.
