7.2.2.5 Instruction and restrictions of use
The internal battery option is not cabled by default and its implementation must be made by us in our factory
(contact us).
When the battery is completely discharged, it takes around three hours to obtain a complete charge.
When the battery is connected and charged, it is not possible to do an On/Off of the device. Only putting the
Reset input (pin 14) to the ground or sending the command
AT+EGMRST
allows a reset of the modem.
The battery cannot be replaced or modified by the user. The device must not be opened, under any
circumstances. For any problem concerning the battery: the device MUST be returned to the factory.
Do not throw the modem and the battery on the fire.
7.2.3 Protections of the power supply
The modem is protected by a F2.5A / L250V or 2A / 32V fuse directly assembled on the power supply cable
supplied with the modem.
The modem is also internally protected against tension peaks of more than 32 V.
Filter guarantees: EMI/RFI protection in input and output and signal smoothing.
7.3 RS232 serial link
7.3.1 general presentation
The RS232 interface provides an adaptation of the tension levels (V24/CMOS
⇔
V24/V28) between the
GSM/GPRS module (DCE) and the communication port of a PC (DTE).
The RS232 interface is internally protected (ESD protection) against electrostatic peaks coming from the
RS232.
Filter guarantees:
EMI/RFI protection in input and output and signal smoothing.
