Chengdu Ebyte Electronic Technology Co.,Ltd.

1. Overview

The serial server series products independently developed by Ebyte integrate the TCP/IP protocol stack, which can
realize two-way transparent transmission of data from serial port to Ethernet port, Modbus protocol conversion, serial
port device cloud and other functions. The industrial design ensures the stability of the equipment in the harsh working
environment, and the rich indicator light effects are used to feedback the different working states of the equipment.
It supports the configuration of the host computer. With simple configuration, the networking and cloud access of serial
devices can be easily realized.
Widely used in computer room monitoring, environmental monitoring, intelligent transportation, gate control, intelligent
express cabinet and other industries.
