1 Introduction

Welcome to Moxa NPort Server Lite, an Industrial Serial Device Server that

greatly enhances the ability of a Windows 95/98/Me/NT/2000/XP host to control

multiple serial devices over a TCP/IP based Ethernet network.

This chapter is an introduction to NPort Server Lite and includes the following:

❑ Features

❑ Product Specifications

❑ Package Checklist

NPort Server Lite provides a data communications solution for connecting

Windows hosts to multiple asynchronous RS-232 (models DE-301/302/304) or

RS-422/485 (models DE-331/332/334) serial ports through a TCP/IP network.

Each model has one (DE-301/331), two (DE-302/332), or four (DE-304/334)

asynchronous serial port connections on one side, and one 10/100 Mbps Ethernet

connection on the other, allowing any device that supports the asynchronous

communications protocol to attach to a network. NPort Server Lite works like an

add-on multiport serial board to the Windows host, but with one major

advantage—the TCP/IP network. Since the Windows host communicates with

the COM ports on NPort Server Lite over a TCP/IP network, you are able to

control asynchronous serial devices from virtually anywhere in the world.

Although it connects through the virtual link of the Ethernet, the ports on NPort

Server Lite are recognized as Real COM ports by the Windows operating system.

NPort Server Lite provides both the basic transmit/receive data functions, as well

as RTS, CTS, DTR, DSR, and DCD control signals.

NPort Server Lite can be used with your existing applications that support serial

communication. It also comes with a utility program providing a simple

step-by-step installation procedure, and a maintenance wizard that gives you

easy access to your asynchronous devices.

2 Connecting the Hardware

Now that you have been introduced to NPort Server Lite's features and

specifications, it’s time to set up the hardware. We cover the following topics in

this chapter:

❑ Choosing a Location

•Desktop

•Wall or Cabinet

•DIN Rail

❑ Network Connection

❑ Power Connection

❑ Serial Connection

Choosing a Location

There are three placement options available. NPort Server Lite can be:

•placed on a desktop,

•fixed to a wall or inside a cabinet, or

•fixed to a 35-mm DIN Rail.

Desktop

One option is to place NPort Server Lite on a clean, flat, well-ventilated desktop.

There are four rubber pads attached to the bottom of the server, and we

recommend leaving sufficient room between NPort Server Lite and neighboring

equipment to create enough clearance for air to circulate.

You should also remember not to put anything on top of NPort Server Lite, since

this could damage the internal components and obscure the server’s LCD panel.

Wall or Cabinet

The two metal brackets included with NPort Server Lite can be used to attach the

server to a wall, or the inside of a cabinet. Using three screws per bracket, first

attach the brackets to the bottom of the server (Fig. 2-1a). Next, use two screws

per bracket to attach the server to a wall or cabinet (Fig. 2-1b).
