5.2 Sleep Modes
DB3 Plug&Play is able to go to Sleep mode after configurable Sleep timeout.
This timeout (defined period) starts counting when the device is in STOP mode.
After timeout is reached and all conditions for sleep mode are met, the device
goes into sleep mode. While in sleep mode, DB3 Plug&Play turns GNSS module
off and it is not making new periodic records. Only event records are being
recorded with last known coordinate and sent to AVL server. As a result power
usage decreases allowing saving vehicle battery.
5.2.1 Sleep Mode
DB3 Plug&Play can enter sleep mode if ALL of these conditions are met :
DB3 Plug&Play has to be configured to work in Sleep mode;
The device must be synchronized time with GNSS satellites;
DB3 Plug&Play has to be in „X on Stop Mode“ (Configured by Mode switch
parameter);
Ignition (Configured to be detected by Power Voltage, Ignition or
Accelerometer) is off;
Sleep timeout is reached.
DB3 Plug&Play exits sleep mode when if ONE of following conditions are true :
DB3 Plug&Play switches to “X on Moving Mode”;
Ignition (Configured to be detected by Power Voltage, Ignition or
Accelerometer) is turned on.
5.2.2 Deep Sleep Mode
While in deep sleep mode, DB3 Plug&Play sets GNSS receiver to sleep mode
and turns off GSM/GPRS module (it is not possible to wake up the device via
SMS). Despite records with last known coordinate are being saved and send to
AVL server (GSM/GPRS module is turned on to send data and after that, it is
turned off again), power usage is decreased to save vehicle’s battery. Note,
