7.2.2.3 Charge voltage and supply voltage
The following table shows the consumptions of the modem with GSM Off and Rs232 disconnected.
These values were measured after a complete discharge of the battery.
Table : Power consumption (2*)
CONDITIONS I Charge Nom.(mA)
T=25°C without RS232
External supply tension @ 5.5V 358
@ 12V 173
@ 24V 92
@ 32V 72
(2*) The power supply consumption may vary by 5% depending on the temperature range (-20 °C to +55 °C).
7.2.2.4 Indication of presence/absence of the external power supply
The modem contains the EGM standard library (see the documents "EG_EGM_CL_xxx_yy" of ERCO &
GENER) in this case, the command AT+GPIOGET=27 allows to know the status of the external power
supply for the internal battery.
AT+GPIOGET=27
<Index>
0 indication of absence of external power supply
