1.Overview

KB3030 GPRS DTU (Data Terminal Unit) is wireless data transmitting terminal of GPRS/SMS and embedded with High reliable ARM7 CPU.

Based on the public net, KB3030 GPRS DTU transmit widely, stably and reliably, KB3030 GPRS DTU is widely used in unattended operation device, Remote AMR, remote data acquisition, remote AMR, remote scheduling and so on. Due to this product is designed for industry integrated, we adopt special designs in the temperature scope, shaking, EMC and interface multiform and so on, to keep it good stability in the severe atmosphere, ensure high quality for your device.

Aim at different scope user’s requirements to supply different define GPRS Terminal unit, it needs taking industry characteristics for developing on hardware & software and system integration. GPRS mobile net can supply TCP/IP connection; GPRS DTU can be use for internet connection, data transmitting application and so on. KB3030 GPRS DTU (Data Terminal Unit) is special GPRS wireless device that send the data from COM port through GPRS mobile data network.

KB3030 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.  

2.Product Feature

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

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

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

       Working Frequency adopt 850MHz/900MHz/1800MHz/1900MHz which is suit for every country all over the world (Including North America and South America);

         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.

       Various working mode: DTU (default), Modem, SMS Modem. DTU mode is GPRS data transmission which can get the data from device’s COM port (RS232/RS485/TTL) and transmit to the server in Internet. It also can receive SMS Message when DTU mode (it needs to switch IO port to SMS when send message). SMS Modem is SMS transmission mode, user can set to type A (with protocol) or type B (transparent). When set to Modem, compatible standard AT command (GSM07.05 and 07.07). user can write AT command software to realize the function user need.

        DTU and SMS Modem can switch through User configuration software and also can change the working modem through IO port. Set the parameter of Modem mode must after it is power-on.

       Strong server software support, application for many years, strong function.

         Support special APN, data center support fixed IP and DDNS.

         Working temperature range: -40°C-80°C, communication is not effected at -40°C.
