Product Descriptions

E840/E841/E842 DTU (EC03xxx) is a cost-effective 4G DTU developed using 4G CAT1 technology. The main function is to achieve bidirectional transparent transmission between serial devices and network servers. Adopting RS485/RS232 interfaces respectively, supporting voltage inputs of 5-36VDC (E840)/8-28VDC (E841)/85-265VAC (E842). There is no limitation on communication distance, and it has the advantages of wide network coverage and strong anti-interference ability. Easy integration into IoT projects.

The equipment adopts a guide rail installation method, which is compact in size and easy to install. By using simple AT commands or configuration software, it is easy to achieve bidirectional data transparent transmission from serial port to network with this product in just a few steps.

The device supports multiple links, MQTT protocol, APN/VPN, and access to OneNet platform, Baidu Cloud platform, and Alibaba Cloud platform, making it easy to implement IoT applications. Supports automatic interconversion between Modbus RTU and Modbus TCP,
