5 MAMBO2 APPLICATION INTERFACE
5.1 Power supply
Your MAMBO is powered by a rechargeable Li-Polymer battery. The power supply
to recharge the internal battery of the MAMBO2 unit is drown from a valid USB port
source which complies exactly with the USB standard. A compliant USB host source
is specified to supply no more than
500 mA
. The USB voltage is used to charge the
internal battery. The current for charging the internal battery of the MAMBO2
device is limited to 450 mA.
5.1.1 Automatic shutdown
Automatic shutdown takes effect if:
•
under voltage is detected when battery level runs low
.
The automatic shutdown procedure is equivalent to the initiated power-down, i.e.
MAMBO2 logs off from the network and the software enters a secure state avoiding
loss of data.
5.1.2 Power saving
SLEEP mode reduces the functionality of the modules of the MAMBO2 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
examples in table below. Following SLEEP modes are supported by the MAMBO2
device:
Ign
Device wakes up when IGN (pin 13 MOLEX, AMP) changes its digital level
from Low to High (performs a rising edge).
Ring
Device wakes up when the GSM module receives an SMS message.
Timer
=1:20:00
Device wakes up after the defined time has expired.
Motion
Device wakes up when motions are detected.
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 the power saving with
"
Ring
" parameter works properly only when PIN authentication has
been done and the device is registered to the GSM network. If you
attempt to activate power saving while the SIM card is not inserted
or the PIN not correctly entered, the device responds error "
ring
shutdown aborted due to bad GSM coverage
" and the power saving
does not take place. For more details refer to the manual
"Mambo2PFALConfigurationReferenceGuide.pdf".
