Brief Introduction
KB8110 4G DTU (Data Terminal Unit) is wireless data transmitting terminal of 4G. It can be suit for all countries all over the world.
Based on the public net, KB8110 4G DTU transmit widely, stably and reliably, KB8110 4G DTU is widely used in unattended operation device, remote data acquisition, 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 4G Terminal unit, it needs taking industry characteristics for developing on hardware & software and system integration. 4G mobile net can supply TCP/IP connection; 4G DTU can be use for internet connection, data transmitting application and so on. KB8110 4G DTU (Data Terminal Unit) is special 4G wireless device that send the data from COM port through 4G mobile data network.
KB8110 4G 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.
