5 OPERATIONAL BASICS

5.1 Operational principals

FM1100 module is designed to acquire records and send them to the server.
Records contain GPS and I/O information. Module uses GPS receiver to acquire
GPS data and is powered with three data acquire methods: time-based,
distance-based and angle-based method. Method's details are described in 5.12
section. All data is stored in flash memory and later can be sent via GPRS or SMS
channels. GPRS mode is most preferred data sending mode. SMS mode is mostly
used in areas without GPRS coverage or GPRS usage is too expensive.
GPRS and SMS
communicates with server using special data protocol. Data protocol is
described in "FMXXXX Protocols" document.
FM1100 can be managed by SMS commands. SMS Command list is
described in SMS COMMAND LIST
performed over TCP or via SMS. Configuration parameters and modes are
described in "FMXXXX Protocols" document.

5.2 Deep Sleep mode

While in deep sleep mode, FM1100 sets GPS receiver to sleep mode and
turns off GSM/GPRS module (it is not possible to wake up device via SMS),
therefore records with last good coordinates are being saved and send to AVL
server if configured (GSM/GPRS module is turned on to send data and after
turned off). Depending on two configurable parameters, send period and min
period, in Deep Sleep mode power usage can be decreased to save vehicle's
battery.
FM1100 can enter deep sleep mode (standby mode) if ALL of these
conditions are met:
• FM1100 has to be configured to work in Deep Sleep mode;
• Startup timeout has elapsed (5 minutes after every restart of the
device);
• No movement by movement sensor is detected;
• Ignition (DIN1) is off (driven logic low);
• Send period in stop mode is more than 60 seconds (Data Acquisition
Mode settings);
• USB cable is not connected.
FM1100 exits deep sleep mode when if ONE of following conditions are true:
• Movement by movement sensor is detected;
• Ignition (DIN1) is turned on (driven logic high);
settings are described
section.
in later sections.
