MC55i-485GI 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. Among its main functions are data transmission by use of CSD and GPRS technologies, reception and transmission of voice signals, faxes and SMS-messages. Modem has RS485 communication interface. Connection to this interface is carried out through terminal connector which allows parallel connection of several external devices. TJ6-6P6C connector is used for the modem power supply. The lines provided in the terminal connector can be used to power the external device. MC55i-485GI 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.
