[Introduction]：EWD95M-400SL22 (485) is a wireless data transmission radio using military-grade LoRa modulation technology.The shell adopts three-proof coating, which is Anti-Fungal, Anti-Humidity, and Anti-Salt Spray. It has multiple transmission modes and operates in the (410.125MHz～493.125MHz) frequency band (default 433.125MHz). The radio provides a transparent RS485/RS232 interface, uses a plastic shell, a guide rail installation structure, and supports 8～28V (DC) wide voltage input. LoRa spread spectrum technology will bring a longer communication distance and has the advantage of strong anti-interference ability.

★Note: When connecting the radio station to multiple devices, there is poor communication, but this phenomenon is not the case with a single device. Please try connecting a 120Ω resistor in parallel between the 485_A terminal and the 485_B terminal.
★EWD95M-400SLxx(xxx) can be powered by 8~28V (DC) power supply, and the wiring port is connected by wiring terminals.
