[Introduction]：E810-DTU(RS485) is a RS485 to Ethernet single serial server that realizes transparent data transmission between RJ45 network port and RS485. The module is equipped with M0+ series 32-bit processor, which has fast running rate and high efficiency. With adaptive network rate (up to support 100M full duplex), TCP Server, TCP Client, UDP Server, UDP Client four communication mechanisms. The product is coated with three-proof paint, with “anti-mold”, “anti-humidity”, “anti-salt spray” and other functions.
