4. Set Port for GPS
After the Set Port for GPS button was tapped (or executed from the keyboard) in the Main Screen
the Set Port for GPS dialog window appears on the screen. This dialog allows you to enable and
disable the GPS input, specify serial communication parameters matching GPS receiver settings, and
to monitor the GPS output in terminal mode (the bottom button). The dialog is presented below.
Description of Options and Parameters:
GPS Input
This option allows you to Enable/Disable a serial port for GPS input. When Disabled is
chosen logging and monitoring screens will display message “GPS disabled” in place of
GPS parameters.
The GPS Input can be Enabled even if there is no GPS system connected to the Allegro.
In such case data file will contain proper sequence of EM61-LX2 readings without any
GPS input.
Tapping on the down arrow next to the text box labeled GPS Input opens a drop-down
box showing the available settings, or when the keyboard is used activate the text box by
pressing TAB key and then by using up or down arrow keys select one of two available
items: Enable and Disable.
Serial Port
The number of serial port that is assigned to the GPS input. Available selections: COM1
to COM12. The program default is COM2. Communication parameters for the selected
serial port can be determined in options described below.
This port must be different than the port specified in the Logger Setup menu (for EM61-
LX2) and Set Output Port dialog, otherwise a message will be displayed and ports will
have to be reassigned.
If Bluetooth communication is employed between computer and GPS receiver please use
serial port number that has been assigned by Windows Mobile operating system to the
Bluetooth connection.
