MG Terminal is a dual-band (900/1800 MHz) GSM modem intended for data transmission via cellular communication. External interfaces: RS232 serial port, TJ-4P4C connector for audio handset connecting, TJ6-6P6C power connector. The main functions include: data transmission by use of CSD and GPRS technologies, reception and transmission of voice signals, faxes and SMS-messages. The modem is controlled by standard AT-commands. MG Terminal is designed to operate in automatic data collecting systems of heat and electricity supply meters, as well as in other systems with wireless data transmission.
