1.1 Product Description

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 the LORA spread spectrum technology, its
strong anti-interference ability, so that the wireless communication in the
industrial field is more stable and reliable.
It has a variety of transmission modes, and the radio provides transparent
RS232/RS485 interfaces.LoRa direct-sequence spread spectrum technology will
bring a longer 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, there
is a certain scope of application: it provides some special conditions under the special network of real-time
monitoring signals, reliable data transmission, has a low cost, easy to install and maintain, strong ability to
bypass the shot, the flexible network structure, the coverage of the characteristics of the range of long distance,
suitable for multi-point and dispersed locations, complex geographic environments and so on occasions, and can
be connected with the PLC, RTU, rain gauge, liquid level meter, and other data terminals.
