Page 3: Product Overview
1. Product overview 1.1.Product Introduction E810-DTU (1RS1E) is a single serial port server that transfers RS232 & RS485 & RS422 to ethernet. It realizes data transparent transmission between RJ45 and RS232 or RS485 or RS422. Equipped with M3 series 32-bit processor, it runs fast and has high efficiency. With adaptive network rate (up to 100M full duplex), TCP Server, TCP Client, UDP Server, UDP Client four communication mechanisms. -

Note: When wiring as full-duplex (RS422) or half-duplex (RS485), in order to prevent signal reflection and interference, a matching resistor (parameter 120 ohm 1/4W) must be connected at the end of the line! Copyright ©2012–2019, Chengdu Ebyte Electronic Technology Co.,Ltd... -
Page 7: Product Function Introduction
DNS is called Domain Name System. The distribution of domain names and IP addresses on the World Wide Web (www) is a database. After the device has the correct DNS server, it can interact with the external network (World Wide Web) server through the network domain name.
