1. Overview

    KB3022 GPRS MODEM is a terminal which embedded industrial class GPRS Module based on the 2.5G Mobile SMS platform, Standard industrial design, support GPRS network, transmit data by SMS(transmission form: HEX, ASCII, UCS2.) and so on. Supply RS232, RS485, TTL interface (User need to clarify the interface information before place order), connect with device directly to achieve wireless connect net and wireless data transmission. 

    KB3022 GPRS MODEM is used in electric power automatic system, industry monitoring, traffic management, atmosphere, POS, vending machine, Mobile Banking, pro-environment, pipe network monitoring, finance, securities departments and so on. Especially suit for the situation which have no condition to connect with Internet in remote mountain. To meet the networking request of all kinds of applications, KB3022 support flexible network plan. It is applicable to small and medium data transmitting of the Center to multi-points, multi-points scatter.
