[Interface]：RS232

[Introduction]：It works in the frequency band (410.125MHz～493.125MHz) (default 433.125MHz). The radio provides a transparent RS485/RS232 interface. Adopt plastic shell, guide rail type installation structure, support 8～28V(DC)/85～265V(AC) voltage input. LoRa spread spectrum technology will bring longer communication distance, and has the advantage of strong anti-interference ability
