The GLONASS/GPS unit of the combined module
is designed to receive signals from the
GLONASS/GPS satellites and determine the geographical coordinates of the receiver antenna
(latitude, longitude and altitude), as well as the exact time (GMT), speed and direction of travel.
GSM/GPRS unit of the combined module
performs the following functions:
⎯
establishment and maintenance of outgoing TCP/IP connection (data reception and
transmission in GPRS mode);
⎯
reception and sending SMS messages.
For information transmission, the GSM/GPRS unit of the combined module establishes and
maintains connection to the server, periodically transmitting information packets. The periods of data
transmission to the server during the parking and during the movement of the vehicle are different
and can be changed by user.
Bluetooth unit of the combined module
provides connection to the PC, wireless information
exchange between the tracker and the ADM Configurator as well as data receipt from wireless
sensors.

⎯
flashes twice
– data from the GLONASS/GPS unit received, but the coordinates are
invalid;
⎯
flashes once
– the GLONASS/GPS unit has determined the time and the valid
coordinates.
The blue LED

⎯
flashes three times - the GSM/GPRS unit is disabled for re-initialization;
⎯
flashes twice - the GSM/GPRS unit is on, but there is no connection to the server;
