1. Introduction

1.1. Brief Introduction

E90-DTU (433C37) is a data transmission station that adopts extremely advanced ultra-narrow band modulation technology. On
the original basis, power amplifier (PA) and low noise amplifier (LNA) are built in, so that the maximum transmitting power reaches
5w and the receiving sensitivity is also improved to a certain extent. Compared with the products without power amplifier and low
noise amplifier, the overall communication stability is greatly improved.
Different from the traditional data transmission station, E90-DTU (433C37) is specially developed for Modbus application
scenarios. The feature of unlimited packet length can replace the communication cable, making it the most convenient choice for
M odbus wireless upgrade. The station works in 433MHz frequency band, with communication distance up to 10km. Wireless digital
radio as a medium of communication, as well as optical fiber, microwave, open wire, there is a certain scop e of application: it provides
some special conditions, private network monitoring signals in real-time and reliable data transmission, low cost, easy installation and
maintenance, diffraction capability is strong, flexible network structure, the coverage is far characteristic, suitable for some more and
occasions, such as dispersion and complex geographical environment with PLC, RTU, rain gauge, level gauge and other data terminal
is connected.
