3. Choose MobileMapper Beacon as the DGPS data source:
, then Programs>GPS Utilities>DGPS Configuration.
- Tap on
- Tap on the Select Mode button.
- In the Select Differential Mode window, enable the Beacon
option and then tap OK. The Settings window opens to let
you configure both the beacon and the connection to this
beacon.
- In the Port field, on top of the screen, set the port through
which you will communicate with the MobileMapper bea-
con. Typically, you will select:
• COM1, if you are using a wire connection to
MobileMapper Beacon.
• COM4, if you are using Bluetooth.
Note that the Update button allows you to update the list of
available ports attached to the Port field. When selecting
Beacon and tapping OK, this update function is automati-
cally run so you don't need to tap this button. Typically,
you need to use this button after you have changed the vir-
tual port in Bluetooth Manager and the Settings window is
already open.
Note that the Configuration button allows you to display the
settings of the selected port. But when selecting Beacon as
the DGPS data source, the settings of the selected port
are in fact forced to 4800 Bd, no parity, 8 data bits and 1
stop bit.
- Tap on the Tune button.
- Choose one of the following options to tune the
MobileMapper Beacon receiver:
• Tune Automatically (automatic method; default choice).
• Tune by Frequency (manual method: you have to specify
the frequency to which you want the receiver to tune).
• Tune By Site (manual method: you have to specify the
region, country and name of the DGPS source, i.e. the
reference station, you want MobileMapper Beacon to
receive) (see screen example opposite).
- Tap OK.
