Abstract
TCP/IP and Internet is widely used in industrial field, yet plenty of industrial equipments do not have network interface and can not be connected to the internet directly.Common communication interface between these equipments is serial port.32 bit ARM microprocessor is used to develop embedded serial port network converter.It gives network interface to these equipments without changing their structure,which provides a low-cost solution for traditional serial-interfaced equipments to connect with the internet through TCP/IP.This device has been put into use in a mechanical manufacturing company now.
