1 Introduction
E90-DTU(xxxSLxx-ETH)_V2.0 supports adaptive network rate (up to
100M full duplex), providing six working modes of TCP Server, TCP Client,
UDP Server, UDP Client, HTTP Client, MQTT Client, while in TCP Server
mode supporting six client connections;
Supporting a variety of Modbus gateways, which can perform simple
interchange of Modbus TCP data and Modbus RTU data, as well as
record and send the read instructions, and also actively upload the server
through pre-stored instructions;
Wireless communication adopts LoRa direct sequence spread spectrum technology, which will bring longer
communication distance and has the advantages of concentrated power density and strong anti-interference ability. With
software FEC forward error correction algorithm, which has high coding efficiency and strong error correction capability,
it can actively correct the interfered packets in the case of sudden interference, which greatly improves the reliability and
transmission distance, and can help users to complete long-distance data transparent transmission efficiently. Users can
make relevant configurations via WEB pages;
E90-DTU(xxxSLxx-ETH)_V2.0 includes the following 6 models:
E90-DTU(230SL22-ETH)_V2.0, E90-DTU(230SL30-ETH)_V2.0, E90-DTU(400SL22-ETH)_V2.0
E90-DTU(400SL30-ETH)_V2.0, E90-DTU(900SL22-ETH)_V2.0, E90-DTU(900SL30-ETH)_V2.0
