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;
  • processor;
  • 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. 

 

Functional capabilities: 

  •  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.
