1.1 Brief Introduction

E90-DTU (900SL33) is a wireless digital transmission station using military LoRa modulation technology, with a
variety of transmission modes, working in 850.125~930.125MHz) frequency band (default 868.125MHz). The station
provides transparent RS232 / RS485 interface and supports 8~28V voltage input. LoRa direct sequence expansion
technology will bring further communication distance, and has the advantages of concentrated power density and strong
anti-interference ability. The module has the software FEC forward error correction algorithm, which has high coding
efficiency and strong error correction ability. In the case of sudden interference, it can actively correct the disturbed data
packets, greatly improving the reliability and transmission distance. In the absence of FEC, such packets can only be
discarded. The radio station has the function of data encryption, and the data transmitted by the radio station is random,
which makes the data interception meaningless through strict encryption and decryption algorithm; supports the
subcontracting length setting and supports different real-time and data packets.
Wireless digital radio as a kind of communication media, and optical fiber, microwave, open line, have certain scope
of application: it provides some special conditions of private network monitoring signal of real-time and reliable data
transmission, with low cost, convenient installation and maintenance, shooting ability, flexible network structure, far
coverage characteristics, suitable for point and scattered, complex geographical environment, and PLC, RTU, rainfall
gauge, liquid level meter data terminal connection.
