Wireless Networking Equipment, gprs modem serial port  

KB3020 GPRS DTU (Data Terminal Unit) is wireless data transmitting terminal of GPRS and embedded with High reliable ARM7 CPU.

KB3020 GPRS DTU is used in electric power automatic system, industry monitoring, traffic management, atmosphere, pro-environment, pipe network monitoring, finance, securities departments and so on. Consider the networking request from different application scope, achieve Virtual data private network in network structure. It is applicable to small and medium data transmitting of the Center to multi-points, multi-points scatter.

Product Feature

l        Standard industrial products, EMC anti-jamming design, strong adaptiveness.

l        Independent research and developing, embedded 32 bit ARM7-CPU with real-time operating system.

l        Embedded Watchdog chip, provide multiple Reset mechanism, can be controlled by software, achieve industrial security mechanism perfectly.

l        Advanced and strict data communication protocol, with the function of correction and encryption. Never lose package when data transmission, can achieve pictures over than 100K and Flash animation files transmission, no Mosaic happened.

l        Various working mode: DTU, Modem, SMS Modem. These three working modes are optional. When set to Modem, single standard AT command (GSM07.05 and 07.07). When SMS Modem, user can set the message transmission with or without protocol.
