E90-DTU(400SL42) LoRa digital radio remote communication, SX1268 wireless data transmission station, RS485/RS232 relay network

Product Descriptions

E90-DTU(xxxSL42) series is a real high-quality industrial-grade wireless digital transmission radio (the radio won the national design patent ZL202030009845.3), the radio adopts LORA spread spectrum technology, and its strong anti-jamming

ability makes the wireless communication more stable and reliable in the industrial site. 

It has a variety of transmission modes, the radio provides transparent RS232/RS485 interface.LoRa direct-sequence spread spectrum technology will bring more communication distance, and has the advantage of strong anti-interference ability. The 

module has software FEC forward error correction algorithm, which has high coding efficiency and strong error correction capability, and can actively correct the interfered data packets in case of sudden interference, greatly improving reliability and 

transmission distance. In the absence of FEC, such packets can only be discarded. The radio has data encryption function, the data transmitted by the radio in the air, with randomness, through the strict encryption and decryption algorithms, which 

makes the data interception lose its significance; it supports the sub-packet length setting, and supports different real-time and data packets. Wireless digital transmission radio as a communication medium, and optical fiber, microwave, open wire, has 

a certain scope of application: it provides some special conditions in the dedicated network of real-time, reliable data transmission of monitoring signals, has a low cost, easy installation and maintenance, bypassing the shooting ability, flexible 

networking structure, coverage of the characteristics of the long range, suitable for multi-point and location of dispersed, geographically complex and other occasions, can be combined with the PLC, RTU. It can be connected with PLC, RTU, rain gauge, 

liquid level meter and other data terminals.
