1 Introduction
Welcome to Moxa 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 NPort Express and includes the following
sections:

NPort Express DE-211 provides a data communications solution for connecting
Windows and Linux hosts to asynchronous serial devices over a TCP/IP Ethernet.
You may connect your Windows 95/98/ME/NT/2000/XP host to a native
RS-232/422/485 serial port, or your PC-based Linux host to a real tty port, through a
TCP/IP Ethernet. With one asynchronous serial port connection on one end, and a
10 Mbps Ethernet connection on the other, NPort Express allows
virtually any serial device to attach to a network. NPort Express works like an
add-on single-port serial board to your PC server, but with one major advantage—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 real tty port by Linux.
NPort Express provides both the basic transmit/receive data functions, as well as
RTS, CTS, DTR, DSR, and DCD control signals.
NPort Express can be used with your existing applications that support serial
communication, and come with a utility program providing a simple step-by-step
installation procedure and a maintenance wizard that gives you easy access to your
asynchronous device.

LED Indicators
NPort Express’s top panel contains five LED indicators, as described in the
following table.

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 when you press
the reset button; see page 1-5 for details.

Housing
DIN Rail
For many industrial applications, you will find it convenient to use the DIN Rail
attachments, as shown below.
STEP 1: Use 2 screws per ear to attach DIN Rail mounts to each of NPort
Express’s two ears.
⇒
STEP 2: Insert the top of the DIN Rail
into slot A of the DIN Rail
mount.
STEP 3: Push the bottom of NPort
Express so that the bottom of
the DIN Rail snaps into slot B
of the DIN Rail mount.
NOTE: The Din Rail mounting kit is an optional accessory.
To remove NPort Express from the DIN Rail, simply reverse Steps 2 and 3 above by
grasping the bottom of the NPort Express unit with both hands, and then using your
fingers to pull down slightly on the DIN Rail mounts at slot B. This releases the
bottom of the DIN Rail from the DIN Rail mount.

2-3
Wall Mount
For many industrial applications, you will find it convenient to mount NPort
Express on the wall, using two screws, as indicated below.
STEP 1: Screw two screws, separated by 7.8 cm, into the wall. The heads of the
screws should be no greater than 6.5 mm in diameter, and the shafts
should be no greater than 3 mm in diameter. Do not screw the screws in
all the way—leave a space of about 2 mm to allow room for sliding the
NPort Express unit’s ears between the wall and the screws.
STEP 2: Insert the two screw heads
through the large parts of the
keyhole shaped apertures, and
then slide NPort Express
downwards, as indicated.
STEP 3: For added stability, simply
tighten the two screws.
To remove NPort Express from the wall mount, simply reverse Steps 2 and 3.

We discuss the following topics:
¾DIP Switch Settings
¾DB25 Female Connector Pinout
¾RS-232 Wiring
¾RS-422 Wiring

DIP Switch Settings
The top panel of NPort Express contains the following table, which describes how to
set up the serial port using the four DIP switches located on NPort
Express’s rear panel.
SW2 SW3 SW4 Serial Interface Mode
SW1 Serial
Connection OFF OFF OFF RS-232
OFF ON ON RS-422
ON RS-232
Console ON OFF ON 4-Wire RS-485 by RTS
ON ON ON 4-Wire RS-485 ADDC
ON OFF OFF 2-Wire RS-485 by RTS
OFF Data
Comm
ON ON OFF 2-Wire RS-485 ADDC

3-2
Switch SW1 controls the function of the serial port (ON, or up, for RS-232
Console connection, and down for Data Communication, such as when NPort
Express is connected to your serial device). Note that after changing the setting of
SW1, NPort Express will reboot to initialize the new setting. You must wait a few
seconds for the green Ready light to blink off and then on again, indicating that the
function of the serial port has been changed.
Switches SW2, SW3, and SW4 control the serial port’s data communication
Interface Mode. (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 setup procedures can be carried out through a Telnet connection,
during which data is transmitted through NPort Express’s Ethernet port.
However, you must set SW1 to the OFF position to establish a Telnet
connection.
