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
❑ Front/Top/Rear/Bottom/Right Panel Views
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).
