1. Product introduce
1.1 Introduction
Serial Device Server - RS232/RS485 to Ethernet converter is an Equipment for convert TCP or UDP socket data
to RS232 or RS485, easy to use, low price, low power, 32 bits arm on board, high speed , high Stability.
This is a multi-functional embedded Ethernet serial data conversion device that integrates a TCP / IP protocol
stack, the user can easily use it to network functionality of embedded devices, upgrade the existing serial devices into a
network function, saving human and material resources and development time, make the product faster to market,
enhance their competitiveness.
There is 10/100M auto detected RJ45 interface, RS232 bound rate up to 230.4Kbps, can work at TCP Client, UDP
and UDP server mode, setup easily via RS232 or RJ45.
1.2 Function Features
