[Introduction]:EWD95M-900GL20P(485) is a wireless data transmission radio based on domestic LoRa transmission technology, with multiple transmission modes, working in the 850.125~930.125MHz frequency band, supporting E290 series domestic LoRa module intercommunication, providing transparent RS485/RS232 interface, using plastic housing, rail installation structure, supporting 8~28V (DC) wide voltage input. The radio uses the new generation of ChirpIoT™ spread spectrum technology, supports half-duplex wireless communication, has high anti-interference and high sensitivity; supports air wake-up, wireless configuration, automatic relay, communication key, AT command, IAP upgrade and other functions, and supports sub-packet length setting. The product is sprayed with three anti-paint, with "anti-mold", "anti-moisture" and "anti-salt spray" functions.
