6. PROGRAMMING WHEN USING OWN SIM CARD
If your own SIM card is used, programming proceeds via SMS commands. The GSM
module requires network connection during programming. If the Mobeye CML2255
runs entirely on batteries, it must first be put into programming mode.
6.1 PROGRAM MODE
To program the unit with SMS commands, the GSM module needs to be open and
connected to the network.
In the situation that the CML2255 is connected to an external power supply, it has
continuous network connection and the unit is permanently in program mode.
A battery-operated Mobeye CML2255 switches to the program mode after pressing
the on/off button for 5 seconds until the LED starts flashing. Alternatively the
batteries are re-inserted.
While searching for the GSM network connection the outside LED flashes green and
red, followed by blinking fast shortly. This process normally takes 10-30 seconds. As
soon as the network has been established and the program mode has been reached
the LED flashes 1 sec. on/1 sec. off (or stays on continuously in case the unit has
been configured yet).
During 3 minutes the GSM module remains active, ready to receive SMS
commands. In a battery-operated unit a time-out occurs if no correct command is
received for 3 minutes, the GSM module switches off in order to save the batteries.
In this low power mode the LED flashes once per 3 seconds.
