Con fi gure the GPS receiver
The navigation application that you install will need to know either that it can communicate
with the GPS receiver using a COM port number or by using an intermediate driver. When
using a COM port number, it appears to the application effectively the same as being
connected to an external GPS receiver – this is known as a virtual COM port.
Since both methods of communicating the GPS data to the applications are supported, this
provides compatibility with a wider range of third-party software.
1. Tap Start > Programs > Settings > System tab > External GPS.
2. On the Programs tab, from the drop-down list select the GPS program port number that you want the operating
system to use for communication with the GPS receiver.
· If the application can use the intermediate driver, select a port number starting with GPD. (TIP: If in doubt, it is
recommended that you try this type of port
fi rst.)
·
If the application must use a COM port, select a port number starting with COM.
3. The Hardware tab is relevant only if using an external GPS receiver. If using the internal GPS receiver, do not worry
about the settings on this tab.
4. On the Access tab, you can control whether or not the Windows Mobile 6.1 operating system applies extra
measures to take care of managing access to the GPS device. Leave a check mark in the Manage GPS
automatically box unless you
fi nd that your application will not work with this setting.
External GPS receiver
You do not need to attach any external device in order to use the integrated GPS receiver.
However, the operating system optionally supports the use of an external GPS attachment. If
you wish to attach an external Bluetooth®enabled device, pair the device via Bluetooth and
proceed with the con fi guration described above. In addition you need to con fi gure the following
settings on the Hardware tab:
· Tap Start > Programs > Settings > System tab > External GPS > Hardware tab :
1. Select the GPS hardware port number to be used by the external GPS receiver from the drop-down list.
2. Choose a Baud rate which is compatible with the external GPS receiver. In general, for best performance, pick the
highest baud rate from the drop-down list that is supported by the hardware. This is the speed at which the data is
transferred between the devices.
