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

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

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

lWorking Frequency adopy 800Mhz,compatible CDMA200 1X technology system.

lAdvanced 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 CDMA 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.

lVarious networking ways: KB3060 can work with NET Converter KB2000 and KB3060 (it is convenient to use CDMA without internet). This can achieve networking of peer to peer, center to multi-points.

lPlug and play: when work with KB2000 or KB3060 of our product, no need to develop any software and hardware, can build large SCADA system.

lAutomatical IP register mechanism, can achieve various server modes, build complete super large SCADA system..

lRemote 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 CDMA Flow Fee when no need to use DTU.

lRemote modify DTU parameters: Support that SMS and data service center modify DTU parameters.

lIO switching valuefunction: Two channels input, two channels IO output. Remote control and reading. Alarm status threshold, automatic alarm signal report function.

lStrong 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.

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

lWorking temperature range: -30°C-75°C, communication is not effected at -30°C.
