NPort Express DE-211 Introduction
7
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 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.
LED Name
LED Color
LED Function
PWR
red
Power is on.
off
Power is off, or power error condition exists.
Link
orange
10 Mbps Ethernet connection.
off
Ethernet cable is disconnected, or has a
short.
Ready
green
NPort Server system is ready.
blinking
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.
off
NPort Server has malfunctioned.
Serial Tx
green
Serial data is being transmitted.
off
Serial data is not being transmitted.
Serial Rx
orange
Serial data is being received.
off
Serial data is not being received.

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.

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.

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.
