Once powered by the USB connection, the expected start-up sequence for the
D2O is as follows:
•
The unit will power up and within 2-5 seconds a light within the
Battery
Switch
should flash a green light twice
•
The D2O now acquires the GPS location, time and date settings which can
take up to 90 seconds
•
Next the start-up sampling configuration and system status information is
prepared for transmission at the next opportunity, before the unit enters
sleep mode
•
Without further intervention the D2O will then wake at the next set sampling
time
•
The unit is now ready to interface via the Serial Terminal software
5.4 START-UP SEQUENCE
To start interfacing to the D2O via the CLI, follow the steps below. For
this example the ‘Tera Term’ software application is used, but equivalent
processes should be available in other Serial Terminal Applications.
1. Start Tera Term
2. On the New Connection Window, select a Serial connection type. From
the drop-down control, select the Communications
Port
that corresponds
to the D2O unit, then click the
OK
Button at the bottom of the window
3. The Terminal window is now shown. Verify the serial connection settings
are correctly setup by going to the
Setup > Serial Port...
menu. The
following serial interface parameters should be used:
5.5 SERIAL TERMINAL SETTINGS
4. Once confirmed click the
New Open
Button to proceed
5. Double press the
Enter
Key until a Chevron character
>
is displayed. The
Chevron
>
indicates the D2O is ready to receive CLI input. If a Chevron
does not appear within a few seconds the D2O may be busy performing
setup or synchronisation tasks with the satellite network - please wait up
to 30 seconds and try again. If no Chevron appears then please refer to the
Serial Terminal Troubleshooting Section for help
6. In the event the D2O re-enters sleep mode, indicated by a
GOODBYE
message on the screen, press the
Enter
key repeatedly until the unit wakes
and a Chevron
>
is once again displayed
