The receiver will communicate with the CDMA network via
the cell phone, and a Bluetooth connection will be used
between the receiver and the cell phone.
It is therefore the SIM card inserted in the cell phone that will
control the connection to the network, and not the receiver
itself. The receiver does not need a SIM card and its phone
function can stay off.
Note that this type of network connection cannot be
combined with Microsoft ActiveSync used through a USB
connection between the receiver and a local computer.
Editing the Default Dialup String
Because your cell phone may be any model, you have to make
sure it will be using the right information to initiate an
Internet connection. This is the role of the dialup string,
which is an internal command allowing the cell phone to
successfully connect to the network.
Your ISP will be instrumental in providing you with this string.
Once it has been returned to you, the dialup string should be
entered in the receiver using the Dialup String utility.
Select > File Explorer and go to \Program Files\GNSS
Service Layer\. Run the dialupstring.exe file by simply
tapping on its name.
The program shows the default dialup string used. Edit the
string to match the one that should be used and then tap on
the
Save button (clicking OK directly would not save your
edits). Then click OK to quit Dialup String and close the
window. If you start Dialup String again, you will now read the
newly saved string and the field name above will read
“Current dialup string” instead of “Default current string”.
Pairing Bluetooth Between Receiver and External Cell
Phone
• Make sure your cell phone is fitted with the SIM card you
purchased from your ISP.
• Turn on the cell phone and make sure its Bluetooth is
enabled and visible. If necessary, refer to the phone
manufacturer’s documentation for more information on
how to operate Bluetooth in this phone.
