MC55iT is a quad-band (850/900/1800/1900 MHz) GSM modem intended for data transmission via cellular communication networks with GPRS support (class 10) and TCP/IP protocol stack. 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. MC55iT is designed to operate in automatic data collecting systems of heat and electricity supply meters, vending sale systems, in automatic payment machines, as well as in other systems with wireless data transmission.
