Switch on the external device providing RTCM corrections 
data.

If you want to use COM1 on MobileMapper CX to commu-
nicate with the external device, connect the adequate 
serial cable between the two units.

Tap on 

, then 

-

Tap on the 

Select Mode button

-

In the Select Differential Mode window, enable the 

RTCM Source option. The Settings window opens to let you 
configure the connection to the external source.

-

In  the 

Port field, on top of the screen, set the port through 

which you will communicate with the external device. By 
default, two ports are available:

• COM1, the only “physical” COM port available on the 

MobileMapper CX. Note that COM1 will not be availa-
ble from the list if it’s used by another application

• COM3, a Bluetooth port that is automatically set at 

power on (see also Local Services on page 53).

Note that the 

Update button allows you to update the list of 

available ports attached to the 

Port field. When selecting 

Other RTCM Source and tapping OK, this update function is 
automatically run so you don’t need to tap this button. 
Typically, you need to use this button after you have 
changed the virtual port in Bluetooth Manager and the 
Settings window is already open.

-

Tap the 

Configuration button to edit or view the settings of 

the selected port. A Test button allows you to test the 
availability of the port.

Tap 

OK to close the Port Configuration window. This takes 

you back to the Setting window.

On this screen, set the 

Real-Time Correction Age Limit 

parameter (see recommendations on page 72)

-

Tap 

OK and then Connect.
