Chapter 1 Introduction
Welcome to Moxa’s NPort Express, a compact palm-sized communications device that allows you
to control RS-232/422/485 serial devices over a TCP/IP Ethernet.
This chapter is an introduction to the NPort Express and includes the following sections:

The NPort Express DE-311 provides a data communications solution for connecting Windows and
Linux hosts to asynchronous serial devices over a TCP/IP Ethernet network. Using the NPort
Express is like adding a serial port to your PC using a serial board, but with the added advantage
of the TCP/IP network. With the NPort Express, Windows hosts can connect to a native serial port
and PC-based Linux hosts can connect to a real tty port, all over a network. Virtually any serial
device can be attached to the NPort Express to become network accessible, and the network can be
configured to allow control of the device from any location in the world.
After driver installation, Windows will recognize the serial port on the NPort Express as a real
COM port; Linux will recognize the port as a real tty port. The NPort Express provides basic
transmit/receive data functions, as well as RTS, CTS, DTR, DSR, and DCD control signals.
The NPort Express can be used with your existing applications and comes with a software utility
and maintenance wizard.

NPort DE-311 Hardware Installation Guide Overview
LED Indicators
The NPort Express’s top panel contains five LED indicators, as described in the following table.
LED Name LED Color LED Function
red Power is on
PWR off Power is off, or power error condition exists
orange 10 Mbps Ethernet connection
green 100 Mbps Ethernet connection
Link
off Ethernet cable is disconnected, or has a short
green The NPort Server is ready
blinking
The NPort is requesting an IP address from the DHCP or
BootP server. After receiving the IP, the LED will stop
blinking.
Note: The LED will also blink while holding down the reset
button; see page 1-5 for details.

Housing
DIN Rail
The DIN rail attachments provide a very convenient installation option for many industrial
applications. Installation instructions are as follows:
STEP 1: Use the screws to attach the DIN rail mounts to the NPort Express’s ears.
⇒
STEP 2: The two ends of the rail mount are
named A and B. Hook the A end over
the top edge of the rail.
STEP 3: Push the unit against the rail. You
should hear the B end clicking into
place over the bottom edge of the rail.

NPort DE-311 Hardware Installation Guide Overview
To remove the NPort Express from the DIN rail, simply reverse Steps 2 and 3 above. Use your
fingers to pull down on the B end, which should release the bracket from the rail.
Wall Mount
Wall installation is another convenient installation option for many industrial applications.
Installation instructions are as follows:
STEP 1: Obtain two screws with heads no greater than 6.5 mm in diameter and shafts no greater
than 3 mm in diameter. At the desired wall location, drive the screws into the wall with
7.8 cm separation between the screws. Do not drive the screws all the way into the wall;
leave about 2 mm clearance.
7.8 cm
6.5 cm
STEP 2: Hang the NPort Express on the two
screws using the apertures on the ears,
and then slide the unit downwards.
STEP 3: For added stability, simply tighten the
two screws.

DIP Switch Settings
The top panel contains a table which describes how to configure the serial port using the three DIP
switches.
SW1 Serial Connection SW2 SW3 Serial Interface Mode
ON Console (19200,N,8,1) --- --- RS-232
OFF OFF RS-232
OFF ON RS-422
ON OFF RS-485 by RTS
OFF Data Comm.
ON ON RS-485 ADDC
The DIP switches are located on the rear panel. SW1 toggles the serial port between data and
console operation (ON or up for serial console operation, and OFF or down for data
communication). Data operation is the normal operating mode for controlling serial devices;
console operation is for accessing the NPort Express configuration parameters. Note that after
modifying SW1 settings, the NPort Express will reboot to initialize the new mode. You must wait
a few seconds for the green Ready LED to blink off and then on again, indicating that the function
of the serial port has been changed.
SW2 and SW3 control the serial port’s data communication interface. Note that RTS stands for
Ready to Send and ADDC stands for Automatic Data Direction Control.
Keep the following points in mind when setting the DIP switches.
•RS-232 Console
To use the serial port as a console connection, such as when using Moxa PComm Terminal
Emulator or HyperTerminal, set SW1 to the ON position.
•Telnet Connection
Some configuration may be carried out through a Telnet connection, during which data is
transmitted through the NPort Express’s Ethernet port. However, you must set SW1 to the OFF
position to establish a Telnet connection.

NPort DE-311 Hardware Installation Guide Ethernet Installation
Connecting to the Ethernet Port
Connecting to a Hub or Switch
For most applications, plug one end of your Ethernet cable into the NPort Express’s
10/100BaseTX port, and the other end into a hub or switch that is connected to your network. In
this case, you should use a standard straight-through Ethernet cable, which is readily available
from many commercial vendors. You may also make your own cable by referring to the following
cable wiring diagram.

The following steps explain how to connect the NPort Express’s power adapter:
1. Plug the power adapter’s DC plug into the DC-IN jack on the NPort Express.
2. Plug the power adapter into an electrical outlet.
Note that there is no on/off switch. The NPort Express will turn on automatically as soon as power
is supplied. The red PWR LED will glow to indicate that the unit is receiving power.

The Telnet console is used to view and modify the unit’s configuration. After installing the unit
into a serial device, administrators configure their device remotely by opening a Telnet console
session over the network. The following examples refer to a Telnet console session on a Windows
98 host, but the same instructions should apply to all Windows operating systems.

Click OK to begin the Telnet session.
At the prompt, enter “1” for ansi/vt100, and then press Enter.
The main menu of the unit’s Telnet console will appear as shown.
Navigating the Telnet Console
Once the Telnet console has been opened, you may navigate through the console using the
following keys:
•Arrow keys: Use the arrow keys to navigate between different options. If the arrow keys do not
