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.

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 STEP 3: Push the bottom of NPort  
into slot A of the DIN Rail  
mount.  
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  
STEP 3: For added stability, simply  
tighten the two screws.

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.

NOTE: When setting up a multidrop network, a daisy-chained network should  
be used. Construct your device-to-device wiring as indicated in the  
above figure.  
Enabling a Termination Resistor  
For RS-422/485 serial communications, when an electrical signal travels through  
two different resistance junctions in a transmission line, the impedance mismatch  
will sometimes cause signal reflection. Signal reflection causes signal distortion,  
which in turn will contribute to communication errors. The solution to this problem  
is to establish the same impedance at the line ends as in the line itself, by  
terminating them with resistors.  
The impedance of the termination resistor should equal the characteristic impedance  
of the transmission line. The resistors should be added near the receiving side.  
3-8  
 
Enabling the Built-In 120 Terminator  
To enable NPort Express’s built-in 120 termination resistor, you must short the  
bottom two pins of jumper 6 (JP6), on DE-211’s circuit board. To do this:  
1. Use a screwdriver to remove DE-211’s outer protective case, and then locate  
JP6, as shown in the figures below.  
2. By default, the top two pins of JP6 are shorted, which means that the built-in  
120 termination resistor is disabled (completely removing the jumper from  
the pins also disables the resistor).  
3. Use the jumper to short the bottom two pins of JP6 to enable the built-in 120 Ω  
termination resistor.  
3-9  
 
Enabling a User-Supplied Terminator  
When using the terminal block, you may install your own external terminator  
resistor by connecting the ends of the resistor directly to inputs 2 and 3, or by  
connecting the two ends of the resistor to the wires that emanate from inputs 2 and 3,  
as shown in the following diagrams.

Connecting to the Ethernet Port  
Connecting to a Hub or Switch  
Connecting to a PC  
Connecting to the Ethernet Port  
Connecting to a Hub or Switch  
For most applications, you will simply plug one end of your Ethernet cable into  
NPort Express’s 10BaseT 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. If  
necessary however, you can make your own cable by referring to the following  
cable wiring diagram.  
 
Connecting to a PC  
In some cases, such as when configuring drivers and software, you will find it  
convenient to hook NPort Express directly to your computer’s Ethernet card. To do  
this, you will need to use a cross-over Ethernet cable. This type of Ethernet cable is  
harder to find, although you can make your own cable by referring to the following  
cable wiring diagram.

Using the Power Adapter  
Using Power Over Serial  
Power Status Check  
Using the Power Adapter  
Take the following steps to connect NPort Express’s power adapter.  
1. Plug the power adapter’s DC plug into NPort Express’s DC-IN jack.  
2. Plug the power adapter into an electrical outlet.  
Note that there is no on/off switch. The server turns on as soon as the connected  
power adapter is plugged into a live outlet. The red PWR light on NPort Express’s  
top panel will glow to indicate that it is receiving power.  
 
Using Power Over Serial  
Take the following steps to set up NPort Express’s Power over Serial option.  
IMPORTANT NOTICE  
You may not use the power adapter and Power Over Serial option at the same time.  
Using both power options at the same time could cause irreparable damage to your  
NPort Express unit.  
(1) To use the 12 – 30 VDC Power over Serial option, enable jumpers JP4 and JP5,  
as illustrated in the following diagram. Note that when using the 12 – 30 VDC  
option, power is supplied via pins 12 and 13:  
5-2  
 
Do NOT force either jumper horizontally, as shown in the  
diagram. Doing so could cause serious damage to your DE-211, or  
to the serial device connected to DE-211’s serial port.  
To use the 5 VDC Power over Serial option, enable jumpers JP2 and  
JP3, as illustrated in the following diagram. Note that when using the  
5 VDC option, power is  
supplied via pins 9 and  
10:  
Do NOT force the jumper to connect the lower pin of JP2 to the  
upper pin of JP3, as shown in the diagram. Doing so could cause  
serious damage to your DE-211, or to the serial device connected  
to DE-211’s serial port.  
Power Status Check  
Use the PWR LED indicator on NPort Express’s top panel to see if it is receiving  
power. A red light indicates that power is being received. The absence of a light  
indicates that power is not being received. If the unit is plugged in, or is receiving  
power over cable, then an unlit PWR LED indicator shows that something is wrong  
with the NPort Express unit’s operation.
