The communicator of GSM is intended for connection to cellular networks of the GSM standard at creation of systems of remote control and monitoring, in systems of telemetry, safety, the notification, etc.
Connection of external devices to a communicator is made via consecutive RS485, RS232 or TTL interfaces. Connection of a communicator to the computer is made by means of the module of coordination IS-USB.
The radio radiating element being a part of a communicator is the built-in three-band E-GSM/GPRS the SIM300 module having "Certificate of conformity", issued by body for certification Giprosvyaz Unitary Enterprise, Republic of Belarus is registered in the register on compliance to technical requirements to radio equipment of system of cellular mobile communication of the GSM 900/1800 standard.
The communicator can be configured for work as usual Gsmmodema which copes AT teams the external equipment, or for work as transparent communication "bridge" through the GSM network for consecutive channel RS485 or RS232.
In the mode of communication "bridge", the communicator automatically connects and supports connection with the same remote communicator or the computer. The main data transmission channel in this mode is GPRS in which the TCP/IP protocols are applied to delivery of packages of data. Each device (subscriber) in the GPRS network receives, at registration at the operator GSM, the unique IP address used then for creation of connection with the subscriber. In this mode, the communicator can be configured as the server when he expects connection of external devices to it or as the client when itself acts as the initiator of connection.
