Product Descriptions
E90-DTU (400SL33) is a wireless data transmission radio using military-grade LoRa modulation technology, with a variety of transmission methods, working in the (410.125~493.125MHz) frequency band (default 433.125MHz), the radio provides
transparent RS232/RS485 interface, support 8~28V voltage input. LoRa direct sequence spread spectrum technology will bring longer communication distance, and has the advantages of concentrated power density and strong anti-interference ability.
The module has a software FEC forward error correction algorithm, which has high coding efficiency and strong error correction ability, and can actively correct the jammed packets in the case of sudden interference, greatly improving the reliability and
transmission distance. In the absence of FEC, such packets can only be dropped. The radio station has a data encryption function, and the data transmitted by the radio in the air has randomness, and the data interception is meaningless through strict
encryption and decryption algorithms; Support subpacket length setting, support different real-time and data packets.
As a communication medium, wireless data transmission radio has a certain scope of application like optical fiber, microwave and open wire: it provides real-time and reliable data transmission of monitoring signals in the private network under certain
special conditions, with low cost, convenient installation and maintenance, strong diffraction ability, flexible networking structure, long coverage characteristics, suitable for many points and scattered, complex geographical environment and other
occasions, can be connected with PLC, RTU, rain gauge, level meter and other data terminals.
Product Features
