1. Introduction
1.1 Brief introduction
E90-DTU(400SL37) is a data transceiver with military-grade LoRa modulation technology.With multiple
transmission modes, it works in the (410.125~493.125MHz) frequency band (default 433.125MHz).The transceiver
provides transparent RS232/RS485 interface and supports10
～
36V voltage input. LoRa direct-sequence spread spectrum
technology will bring longer communication distances, and has the advantages of concentrated power density and strong
anti-interference ability. It features a software FEC forward error correction algorithm, which has high coding efficiency
and strong error correction capability. In the case of sudden interference, it can proactively correct the interfered data
packets, greatly improving reliability and transmission distance. In the absence of FEC, such packets can only be
discarded. It has data encryption. The data transmitted by the transceiver over the air is random, and the data interception
is meaningless through strict encryption and decryption algorithms. Packet length setting is available to support different
real-time and data packets.
As a communication medium, wireless data transceiver has the same scope as optical fiber, microwave and bright
line: it provides real-time and reliable data transmission of monitoring signals in private networks under certain special
conditions, with low cost, installation and maintenance. It is convenient, has strong diffraction ability, flexible
networking structure and long coverage. It is suitable for occasions with many points and scattered, complex
geographical environment, etc. It can be connected with PLC, RTU, rain gauge, liquid level meter and other data
terminals.
