GPRS MODEM-CONTROLLER GMC-1
The GMC-1 is intended for acquisition and transmission of data, about of controllable object condition, through a cell-communication network to the server.
The GMC-1 includes:
- the SIM900 system from GPRS module;
- signals matching module ;
- external GSM-antenna.
The modular construction of the device and presence of the programmed processor allow using it in various systems of remote supervision and management.
The clock of a real time and reserve Li-Ion the accumulator , providing operation of controller at switching-off of an external feeding are built in the controller.
The device supports following interfaces: RS-485, RS-232, I2C, SPI, ONEWire.
- SMS sending and receiving;
- Data transmission and reception by GPRS;
- Reception and transmission of voice calls;
- Indication about of registration in the GSM network;
- Presence of dialing fixing number;
- Access implementation to SIM only through defined GSM network’s operator.
