Brief Introduction

KB8111 embedded 4G DTU Module (Data Terminal Unit) is 4G/GSM transparent wireless data transmission terminal and embedded with high reliable ARM 7 CPU. It is applicable to small and medium data transmission with the characters of center to multi-points and multi-points scatter.

    

4G mobile net can supply TCP/IP connection, and 4G DTU can be used for internet connection and data transmitting application. KB8111 is wireless data transmission device, which can realize data transmission from COM port through 4G mobile network. Aim at different requirements of users from different fields, combining with industry characteristics, we can supply special designed 4G terminal unit for users by developing hardware, software and making system integration.

Based on the public net, KB8111 transmit widely, stably and reliably. It is widely used in unattended operation device, remote data acquisition, remote AMR, remote scheduling and other fields. KB8111 is designed for industry integrated. In order to keep good stability in the severe atmosphere, we adopt special designs in temperature scope, shaking, EMC, interface multiform, et, al.

Additionally, KB8111 can be used in electric power automatic system, industry monitoring, traffic management, Meteorological monitoring, pro-environment project, pipe network monitoring, finance, securities departments and so on. Considering the networking requests from different application scope, KB8111 can support network structure of virtual private network (VPN).

Appearance and Interface

Product Feature

•  Standard industrial products, EMC anti-jamming design, strong adaptiveness.
•  Embedded Watchdog chip, provide multiple Reset mechanism, can be controlled by software, achieve industrial security mechanism perfectly.
•  Global frequencies and bands can be used in all countries all over the world.
•  Modify parameters expediently: you can modify parameters by Mobile or Notebook at close quarters by Wi-Fi and you can modify DTU parameters by server remote too.
•   Support wireless remote update program, you can update DTU program by OTA;
•  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.
• Automatically IP register mechanism, can achieve various server modes, build complete super large SCADA system..
•  IO switching value function: Two switch inputs, two switch outputs. Through 4G network to control the state of the switch input or query switch input.Remotely turn on the alarm,set the input alarm mode(4G alarm) and alarm threshold(low level alarm or high level alarm),the user also can customize the alarm information content.
•  Powerful communication backup function:if you open an alternate service functions,the main server and backup server connection can antomatically switch,and antomatically connect to the backup server once the main server problems.
•  Strong server software support, application for many years, strong function.
•  Support fixed IP and DDNS, dedicated APN.
•  Working temperature range: -40℃-80℃, communication is not effected at -40℃.
