E90-DTU(230SL22) 220~236MHz 22dBm LoRa long range RS232/RS485 TCXO auto repeater RSSI SX1262 Transceiver Modem

Product Descriptions

E90-D'TU (230SL.22) is a data transceiver with military-grade LoRa modulation technology. With multiple transmission modes, itworks in the (220.125-236.125MHz) ffequency band (default 230.125MHz). The transceiver provides transparent RS232/RS485interface and supports 8~. 28V voltage input. LoRa direct-sequence spread spectrum technology will bring longer communicationdistances, and has the advantages of concentrated power density and strong anti-interference ability. It features a soltware FEC forwarderror correction algorithm, which has high coding eficiency and strong error correction capability. In the case of sudden interferenceit can proactively correct the interfered data packets, greaty improving reliability and transmission distance. In the absence of FECsuch packets can only be discarded. It has data encryption. The data transmited by the transceiver over the air is random, and the datainterception is meaningless through strict encryption and decryption algorithms.Packet length setting is available to support diferentreal-time and data packets.

It works in the ISM 230MHz band with a communication distance of up to 5km. As a communication medium, wireless datatransceiver has the same scope as optical fiber, microwave and bright line: it provides real-time and reliable data transmission ofmonitoring sienals in private networks under certain special conditions, with low cost, installation and mantenance. It is convenienthas strong difiraction ability, fexible networking structure and long coverage. It is suitable for occasions with many points andscaltered. complex geographical environment. etc, It can be connected with PLC, RTU, rain gauge. liquid level meter and other dataterminals.

Product Features
