IntroductionIntroduction

Welcome to Moxa NPort Express, a compact palm-sized communica-

tion device that allows you to control serial devices over a TCP/IP

based Ethernet.

This chapter is an introduction to NPort Express and includes the fol-

lowing sections:

q Package Checklist

q TCP/IP Description

NPort Express provides a data communication solution for connecting

Windows and Linux hosts to asynchronous serial devices over a

TCP/IP based Ethernet. You may connect your Windows

NT/95/98/2000 host to a native RS-232/422/485 serial port, or your

PC-based Linux host to a fixed tty port, through a TCP/IP Ethernet.

With one asynchronous serial port connection on one end, and a

10/100 Mbps Ethernet connection on the other, NPort Express allows

any device that supports primarily the asynchronous communications

protocol to attach to a network. NPort Express works like an add-on

single-port serial board to your PC server, but with one major advan-

tage— the TCP/IP network. Since the host communicates with the

COM port on Nport Express over a TCP/IP network, you are able to

control your asynchronous serial device from virtually any location.

Although it connects through the virtual link of the Ethernet, the port

on NPort Express is recognized as a real COM port by Windows or a

fixed tty port by Linux. NPort Express provides both the basic trans-

mit/receive data functions, as well as RTS, CTS, DTR, DSR, and

DCD control signals.

NPort Express can be used with your existing applications that sup-

port serial communication, and comes with a utility program provid-

ing a simple step-by-step installation procedure and a maintenance

wizard that gives you easy access to your asynchronous device.
