Chapter 1 Overview

1.1 Introduction

E95-DTU (400F20-485) is a cost-effective wireless data transmission radio station with multiple transmission methods. It works in the
(410～510MHz) frequency band (default 433MHz). The radio provides a transparent RS485 interface, adopts a plastic shell, and is
mounted on a guide rail. Structure, support 8 ～ 28V voltage input. LoRa spread spectrum technology will bring a longer
communication distance and has the advantage of strong anti-interference ability.
As a communication medium, wireless data transmission station has a certain scope of application like optical fiber, microwave and
open wire: it provides real-time and reliable data transmission of monitoring signals in private networks under certain special
conditions, with low cost, installation and maintenance Convenience, strong diffraction ability, flexible network structure, and long
coverage, suitable for many and scattered locations, complex geographical environment and other occasions, can be connected with
PLC, RTU, rain gauge, level gauge and other data terminals.
