KB3030 GPRS DTU (Data Terminal Unit) is wireless data transmitting terminal of GPRS/SMS and embedded with High reliable ARM7 CPU.
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.
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 Working Frequency adopt 850MHz/900MHz/1800MHz/1900MHz which is suit for every country all over the world (Including North America and South America);
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 (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.
l 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.
l Various networking ways: KB3030 can work with NET Converter KB2000 and KB3030 (it is convenient to use GPRS without internet). This can achieve networking of peer to peer, center to multi-points.
l Plug and play: when work with KB2000 or KB3030 of our product, no need to develop any software and hardware, can build large SCADA system.
l Automatical IP register mechanism, can achieve various server modes, build complete super large SCADA system.
l Remote sleep and awake: User can use appointed cell phone number to dial or send message can sleep or awake DTU, it is convenient for user to save a lot of GPRS Flow Fee when no need to use DTU.
l Remote modify DTU parameters: Support that SMS and data service center modify DTU parameters.
l IO switching value function: Two channels input, two channels IO output. Remote control and reading. Alarm status threshold, automatic alarm signal report function.
l Strong communication backup function: Support automatic switching between main server and backup server, support TCP and UDP automatic switchover (now don’t have TCP and UDP automatic switching function). It will connect to backup server when main server has problem, and will take UDP to communication once TCP off line.
