[Introduction]：EWD95M-433GF20(485) is a wireless data transmission radio using GFSK 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 (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 8～28V (DC) wide voltage input. GFSK modulation technology can transmit more data within limited spectrum resources.
