[Introduction]：EWD95M-433GF20(485) is a wireless data transmission radio using GFSK modulation technology. It has multiple transmission modes and operates in the (410MHz～450MHz) frequency band (default 433MHz). The radio provides a transparent RS485/RS232 interface, uses a plastic shell, a guide rail installation structure, and supports 5～28V (DC) wide voltage input. GFSK modulation technology can transmit more data within limited spectrum resources. The radio supports air wake-up, wireless configuration, relay networking, communication keys and other functions. It also has data encryption function. Through strict encryption and decryption algorithms, it ensures data security and improves communication reliability and transmission efficiency.
