KB3061 CDMA Data Terminal Unit

1. KB3061 CDMA DTU Brief Introduction

KB3061 CDMA DTU (Data Terminal Unit) is wireless data transmitting terminal of CDMA and embedded with High reliable ARM7 CPU. It is applicable to small and medium data transmitting of the Center to multi-points, multi-points scatter.
Based on the public net, KB3061 CDMA DTU transmit widely, stably and reliably, KB3061 CDMA 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.
CDMA mobile net can supply TCP/IP connection; CDMA DTU can be use for internet connection, data transmitting application and so on. KB3061 CDMA DTU (Data Terminal Unit) is special CDMA wireless device that send the data from COM port through CDMA mobile data network. Aim at different scope user’s requirements to supply different define CDMA Terminal unit, it needs taking industry characteristics for developing on hardware & software and system integration.
KB3061 CDMA 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.

2. KB3061 CDMA DTU Feature

  • Standard industrial products, EMC anti-jamming design, strong adaptiveness.
  • Independent research and develop, 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 800 MHz, compatible CDMA200 1X technology system.
  • 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) and 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. When set to Modem, compatible standard AT commands (GSM07.05 and 07.07). User can write AT command software to realize the function user need.
  • Various networking ways: KB3061 can network with NET Converter KB2000 and KB3061 (it is convenient to use CDMA without internet). This can achieve networking of point-to-point, center to multi-points.
  • Plug and play: when work with KB2000 or KB3061 of our product, no need to develop any software and hardware, can build large SCADA system.
  • Automatically IP register mechanism, can achieve various server modes, build complete super large SCADA system.
  • 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 CDMA Flow Fee when no need to use DTU.
  • Remote modify DTU parameters: Support that SMS and data service center modify DTU parameters.
  • IO switching value function: Two channels input, two channels IO output. Remote control and reading. Alarm status threshold, automatic alarm signal report function.
  • Strong communication backup function: Support automatic switching between main server and backup server, It will connect to backup server when main server has problem.
  • Strong server software support, Application server software for many years, powerful and stable;
  • Support special APN, data center support fixed IP and DDNS.
  • Working temperature range: -30℃-75℃,communication is not effected at -30℃.

3. Safe Use

KB3061 CDMA DTU Completely complied with national radio product safety technical regulations.
Warm Tip: You must not touch the antenna with your hands or body. During 15 seconds after KB3061 DTU started, Please keep away from the antenna. If the antenna is damaged, you must replace it in time, assorted and qualified cable and antenna.

4. EMI

Now most electric device all has electromagnetic pulse hardening, but some old device may have no, under RF power radiation, it may go wrong. When you use KB3061 CDMA DTU, please check the device nearby have electromagnetic pulse hardening or not.
