I. Product Overview

YT-6802A serial port server is an industrial grade RS232/485/422 serial port with photoelectric isolation that converts and transmits the Ethernet TCP/IP protocol in a bidirectional manner. It transforms traditional serial port communication into network communication, achieving fast networking of serial port devices. The converter adopts a transparent transmission method, and users do not need to be aware of the complex TCP/IP protocol. They can achieve network connection of existing serial devices without changing the program, saving you valuable time and existing investment. Simple and flexible configuration and extremely reliable performance meet any demanding application, making it your ideal choice.
