DISCO-B5-MAGNET H
5.1.3 Power saving
SLEEP mode reduces the functionality of the modules of the DISCO-B5-MAGNET device to a
minimum and thus minimizes the current consumption to the lowest level. Settings can be
made using the $PFAL,Sys.Device.Sleep command. For details, see example in table below.
Following SLEEP modes are supported by the DISCO-B5-MAGNET device:
Modes
Description
IGN
Device goes to sleep and wakes up when the device is removed from the asset (both buttons on
the back of the device changes their state from Low to High).
Ring
Device goes to sleep and wakes up when the GSM module receives a voice call or an SMS.
Timer=1:20:00
Device goes to sleep and wakes up after the defined time has expired.
Motion=5,20,20
Device goes to sleep and wakes up when motion is detected.
ExtPwrDetect
Device goes to sleep and wakes up when external power (higher than 9 V) is connected to the
device.
ExtPwrDrop
Device goes to sleep and wakes up when external power is disconnected or it drops below 8 V.
Example
$PFAL,Sys.Device.Sleep=IGN+Ring+Timer=1:20:00
IMPORTANT:
The sleep and wake-up procedures are quite different depending on the selected
sleep mode. Please keep in mind that the power saving with "Ring" parameter
works properly only when PIN authentication has been done and the device is
already registered in the GSM network. If you attempt to activate power saving
while the device is not registered in the GSM network, the SIM card is not inserted
or the PIN not correctly entered, the device responds with an error "ring shutdown
aborted due to bad GSM coverage" and the power saving does not take place. For

NOTE
(This note is related to the battery-powered devices only): The internal battery pack of the
DISCO-B5-MAGNET must have enough power to safely wake up the device from a sleep mode.
If the internal battery of the DISCO-B5-MAGNET device does not have enough power, the
device cannot complete the wake up operation.
