3 Relevance of the LEDs
At the front side of the device, a green and a yellow
LED indicate the operational status of EasyTrack.
Immediately after switching on the EasyTrack, its
boot loader is started which allows the upload of new
EasyTrack firmware. During this time (approx. 2
seconds) both LEDs flash rapidly. After that the
yellow LED indicates that the hardware check is
carried out. Following the hardware check, the yellow
LED is turned off and the green LED flashes slowly.
In this case the device is ready to operate - but it is
still waiting for a valid GPS-position. The green LED
will stay on permanently once the GPS position
connection has been established.
The yellow LED indicates the state of Dig. Input 1. If
you have connected the EasyTrack to permanent
power and your vehicles ignition is connected to Dig.
Input 1, the Yellow LED will be permanently on when
activated by the ignition. (SMS transfer enabled) and
turn off while ignition is off (SMS disabled).
Additionally there is an internal activity of the GSM-Modem
displayed by flashing on the yellow LED.
The duration of the flashing helps you to determine the
actual operation of the GSM-Modem:
short (approx. 0,5s):
EasyTrack checks incoming SMS.
medium (approx. 2..4s): Sending SMS
long (> 6s) :
SMS cannot be sent
Since firmware version 2.3 the yellow LED flashes slowly
when the GSM filed intensity is below 10%, so this is an
indicator (like the green LED for GPS), that no net is
available to send an SMS.
If the yellow LED flashes very quick with the following
pattern: 3 time on, then pause (and so on), then a GSM error
exists. Either no SIM card or the wrong PIN are entered.
Connect a laptop to the EasyTracks serial port to see the
details.
