power module terminal. The power module is connected by a cable to the motherboard of the cen-
tral. Power is necessary with the use of a GSM/GPRS module. A backup battery is on the mother-
board in case of a power failure.
3.3.5 GPRS module
The GSM function allows to connect to the radio central Supercom 646 by using the GSM net-
work. This remote connection can be established through a computer connected to a modem.
The GPRS function allows sending data of radio devices read by the Supercom 646 on a FTP
server via the GPRS network. It is also possible to send and receive SMS messages by the GSM
network to see the status of the radio central. The functionalities through the GSM network are also
possible.
If the central is equipped with a GSM/GPRS module, insert the SIM card in the SIM card holder
and press the « Reset » - button located on the motherboard. A power source must be connected
to the GSM/GPRS module that the activation happens correctly.
Together with the GPRS module it’s important to choose the right subscription. Mobile
communications services may greatly vary between countries and providers.
