NPort 5400 Series User’s Manual  
Introduction  
Overview  
NPort 5400 Series serial device servers are designed to make your industrial serial devices Internet  
ready instantly. The compact size of NPort 5400 device servers makes them the ideal choice for  
connecting your RS-232 (NPort 5410) or RS-422/485 (NPort 5430/5430I) serial devices—such as  
PLCs, meters, and sensors—to an IP-based Ethernet LAN, making it possible for your software to  
access serial devices anywhere over a local LAN or the Internet.  
NPort 5400 serial device servers ensure the compatibility of network software that uses a standard  
network API (Winsock or BSD Sockets) by providing TCP Server Mode, TCP Client Mode, and  
UDP Mode. And thanks to NPort’s Real COM/TTY drivers, software that works with COM/TTY  
ports can be set up to work over a TCP/IP network in no time. This excellent feature preserves  
your software investment and lets you enjoy the benefits of networking your serial devices  
instantly.  
NPort 5400 serial device servers support automatic IP configuration protocols (DHCP, BOOTP)  
and manual configuration via NPort’s handy web browser console. Both methods ensure quick and  
effective installation. And with NPort 5400’s Windows Utility, installation is very straightforward,  
since all system parameters can be stored and then copied to other device servers simultaneously.

Connecting the Hardware  
This section describes how to connect NPort 5400 to serial devices for first time testing purposes.  
We cover Wiring Requirements, Connecting the Power, Grounding NPort 5400 Series,  
Connecting to the Network, Connecting to a Serial Device, and LED Indicators.  
Wiring Requirements  
ATTENTION  
Safety First!  
Be sure to disconnect the power cord before installing and/or wiring your NPort 5400 Series.  
Wiring Caution!  
Calculate the maximum possible current in each power wire and common wire. Observe all  
electrical codes dictating the maximum current allowable for each wire size.  
If the current goes above the maximum ratings, the wiring could overheat, causing serious  
damage to your equipment.  
Temperature Caution!  
Please take care when handling NPort 5400. When plugged in, NPort 5420/5430/5430I’s internal  
components generate heat, and consequently the casing may feel hot to the touch.  
You should also heed the following:  
y
y
Use separate paths to route wiring for power and devices. If power wiring and device wiring  
paths must cross, make sure the wires are perpendicular at the intersection point.  
NOTE: Do not run signal or communication wiring and power wiring in the same wire conduit.  
To avoid interference, wires with different signal characteristics should be routed separately.  
You can use the type of signal transmitted through a wire to determine which wires should be  
kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can  
be bundled together.  
y
y
Keep input wiring and output wiring separate.  
Where necessary, it is strongly advised that you label wiring to all devices in the system.  
Connecting the Power  
Connect the 12-48 VDC power line with NPort 5400’s terminal block. If the power is properly  
supplied, the “Ready” LED will show a solid red color until the system is ready, at which time the  
“Ready” LED will change to a green color.  
Grounding NPort 5400  
Grounding and wire routing helps limit the effects of noise due to electromagnetic interference  
(EMI). Run the ground connection from the ground screw to the grounding surface prior to  
connecting devices.

Initial IP Address Configuration  
When setting up your NPort 5410/5430/5340I for the first time, the first thing you should do is  
configuring the IP address. This chapter introduces the method to configure NPort’s IP address.  
Select one of the initial IP Address configuration methods to configure NPort’s IP Address. For  
more details about network settings, see the Network Settings section from Chapter 5, Web  
Console Configuration.

NPort 5400 Series User’s Manual  
Choosing the Proper Operation Mode  
Initializing NPort’s IP Address  
1. Determine whether your NPort needs to use a Static IP or Dynamic IP (either DHCP or  
BOOTP application).  
2. If NPort is used in a Static IP environment, you can use LCM Display, NPort Administration  
Suite, ARP, Web Console, or Telnet Console to configure the new IP address.  
3. If NPort is used in a Dynamic IP environment, you can use LCM Display, NPort  
Administration suite, Web Console, or Telnet Console to configure NPort to get an IP address  
dynamically with DHCP, DHCP/BOOTP, or BOOTP.  
ATTENTION  
Consult your network administrator on how to reserve a fixed IP address for your NPort 5400 in  
the MAC-IP mapping table when using a DHCP Server or BOOTP Server. In most applications,  
you should assign a fixed IP address to your NPor.  
Factory Default IP Address  
NPort products are configured with the following default private IP address:  
Default IP address: 192.168.127.254  
(IP addresses of the form 192.168.xxx.xxx are referred to as private IP addresses, since it is not  
possible to directly access a device configured with a private IP address from a public network.  
For example, you would not be able to ping such a device from an outside Internet connection.  
NPort applications that require sending data over a public network, such as the Internet, require  
setting up the server with a valid public IP address, which can be leased from a local ISP.)  
LCM Display  
We recommend using LCM display and four push buttons to configure the IP address at the first  
time installation.  
Basic Operation  
If the NPort is working properly, the LCM panel will display a green color. The red Ready LED  
will also light up, indicating that the NPort is receiving power. After the red Ready LED turns to  
green, you will see a display similar to:

NPort 5400 Series User’s Manual  
Choosing the Proper Operation Mode  
There are four push buttons on NPort’s nameplate. Going from left to right, the buttons are:  
Button Name  
Action  
MENU menu  
activates the main menu, or returns to a lower level  
scrolls up through a list of items shown on the LCM panel’s second line  
U
up cursor  
V
down cursor scrolls down through a list of items shown on the LCM panel’s second line  
selects the option listed on the LCM panel’s second line  
SEL  
select  
The buttons are manipulated in a manner similar to the way a modern cellular phone operates. As  
you move through the various functions and setting options, note that the top line shows the  
current menu or submenu name, and the bottom line shows the submenu name or menu item  
which is activated by pressing the sel button.  
Detailed Menu Options  
The best way to explain all of NPort’s LCM functions is to refer to the tree graph shown in the  
next page. There are three main levels—1, 2, and 3—with each level represented by a separate  
column.  
The first thing to remember is that the menu button is used to move back and forth between the  
LCM panel’s default screen, and main menu screen:

In addition, you only need to remember to:  
Use the sel button to move up one level (i.e., left to right on the tree graph)  
Use the menu button to move down one level (i.e., right to left on the tree graph)  
Use the cursor keys, U and V, to scroll between the various options within a level (i.e.,  
up and down on the tree graph).  
As you use the buttons to operate the LCM display, you will notice that with very few  
exceptions, moving up one level causes the bottom line of the display to move to the top  
line of the display. You will also notice that the bottom three options in level 2, and all of  
the options in level 3 have either a C or D attached.  
The meaning is as follows:  
C = configurable  
I.e., you are allowed to change the setting of this option  
D = display only  
I.e., the setting for this option is displayed, but it cannot be changed (this does NOT  
necessarily mean that the number doesn’t change; only that you can’t change it)

The part of the LCM operation that still requires some explanation is how to edit the  
configurable options. In fact, you will only encounter two types of configurable options.  
The first type involves entering numbers, such as IP addresses, Netmasks, etc. In this case,  
you change the number one digit at a time. The up cursor (U) is used to decrease the  
highlighted digit, the down cursor (V) is used to increase the highlighted digit, and the sel  
button is used to move to the next digit. When the last digit has been changed, pressing sel  
simply enters the number into NPort Server Lite’s memory.

The second type of configurable option is when there are only a small number of options  
from which to choose (although only one option will be visible at a time). Consider the  
PARITY attribute under PORT SETTING as an example. Follow the tree graph to arrive at  
the following PARITY screen. The first option, NONE, is displayed, with a down arrow all

NPort Administration Suite  
NPort Administration Suite consists of some useful utility programs that are used to configure and  
manage your NPorts.  
See Chapter 5 for details on how to install NPort Administration Suite, and how to use this  
suite of useful utilities to set up IP addresses and configure your NPort.  
ARP  
You can make use of the ARP (Address Resolution Protocol) command to set up an IP address for  
your NPort. The ARP command tells your computer to associate the NPort’s MAC address with  
the intended IP address. You must then use Telnet to access the NPort, at which point the Device  
Server’s IP address will be reconfigured.  
ATTENTION  
In order to use this setup method, both your computer and NPort must be connected to the same  
LAN.  
Or, you may use a cross-over Ethernet cable to connect the Nport directly to your computer’s  
Ethernet card.  
Your NPort must be configured with the factory default IP address192.168.127.254before  
executing the ARP command, as described below.  
3-6  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
NPort 5400 Series User’s Manual  
Choosing the Proper Operation Mode  
Take the following steps to use ARP to configure the IP address:  
1. Obtain a valid IP address for your NPort from your network administrator.  
2. Obtain the NPort’s MAC address from the label on its bottom panel.  
3. Execute the ‘arp -s’ command from your computer’s MS-DOS prompt by typing:  
arp –s 192.168.200.100 00-90-E8-xx-xx-xx  
This is where 192.168.200.100 is the new IP address and 00-90-E8-xx-xx-xx is the MAC  
address for your NPort. You will need to change both numbers, as described above in points 1  
and 2.  
4. Next, execute a special Telnet command by typing:  
telnet 192.168.200.100 6000  
After issuing this command, a Connect failed message will appear, as shown here. After the  
NPort reboots, its IP address should be updated to the new address, and you can reconnect  
using either Telnet, Web, or Administrator to check that the update was successful.  
Telnet Console  
Depending on how your computer and network are configured, you may find it convenient to use  
network access to set up your NPort’s IP address. This can be done using the Telnet program.  
1. From the Windows desktop, click on Start and then select Run.  
2. Type telnet 192.168.127.254 (use the correct IP address if different from the default)  
in the Open text input box, and then click OK.  
3. When the Telnet window opens, if you are prompted to input the Console password, input  
the password and then press Enter.  
Note that this page will only appear if the NPort is password protected.

NPort 5400 Series User’s Manual  
Choosing the Proper Operation Mode  
Overview  
NPort Device Servers network-enable traditional RS-232/422/485 devices, in which a Device  
Server is a tiny computer equipped with a CPU, real-time OS, and TCP/IP protocols that can  
bi-directionally translate data between the serial and Ethernet formats. Your computer can access,  
manage, and configure remote facilities and equipment over the Internet from anywhere in the  
world.  
Traditional SCADA and data collection systems rely on serial prots (RS-232/422/485) to collect  
data from various kinds of instruments. Since NPort Serial Device Servers network-enable  
instruments equipped with an RS-232/422/485 communication port, your SCADA and data  
collection system will be able to access all instruments connected to a standard TCP/IP network,  
regardless of whether the devices are used locally or at a remote site.  
NPort is an external IP-based network device that allows you to expand the number of serial ports  
for a host computer on demand. As long as your host computer supports the TCP/IP protocol, you  
won’t be limited by the host computer’s bus limitation (such as ISA or PCI), or lack of drivers for  
various operating systems.  
In addition to providing socket access, NPort also comes with a Real COM/TTY driver that  
transmits all serial signals intact. This means that your existing COM/TTY-based software can be  
preserved, without needing to invest in additional software.  
Three different Socket Modes are available: TCP Server, TCP Client, and UDP Server/Client. The  
main difference between the TCP and UDP protocols is that TCP guarantees delivery of data by  
requiring the recipient to send an acknowledgement to the sender. UDP does not require this type  
of verification, making it possible to offer speedier delivery. UDP also allows multicasting of data  
to groups of IP addresses.  
ATTENTION  
Pictures in this Chapter will use NPort 5400 series as an example.  
Real COM Mode  
NPort comes equipped with COM drivers that work  
with Windows 95/98/ME/NT/2000/XP systems, and  
also TTY drivers for Linux systems. The driver  
establishes a transparent connection between host  
and serial device by mapping the IP:Port of the  
NPort’s serial port to a local COM/TTY port on the  
host computer. This operation mode also supports up  
to 4 simultaneous connections, so that multiple hosts  
can collect data from the same serial device at the  
same time.

NPort 5400 Series User’s Manual  
Choosing the Proper Operation Mode  
ATTENTION  
The driver used for Real COM Mode comes with the NPort Windows Administrator. The driver  
is installed automatically on your computer when you install NPort Administration Suite.  
The important point is that Real COM Mode allows users to continue using RS-232/422/485 serial  
communications software that was written for pure serial communications applications. The driver  
intercepts data sent to the host’s COM port, packs it into a TCP/IP packet, and then redirects it  
through the host’s Ethernet card. At the other end of the connection, the NPort accepts the Ethernet  
frame, unpacks the TCP/IP packet, and then transparently sends it to the appropriate serial device  
attached to one of the NPort’s serial ports.  
ATTENTION  
Real COM Mode allows several hosts to have access control over the same NPort. The driver  
that comes with your NPort controls host access to attached serial devices by checking the host’s  
IP address.  
Modify the Accessible IP Setting table when the legal IP address should be required in your  
application  
TCP Server Mode  
In TCP Server mode, NPort provides a unique IP:Port  
address on a TCP/IP network. NPort waits passively to  
be contacted by the host computer, allowing the host  
computer to establish a connection with and get data  
from the serial device. This operation mode also supports  
up to 4 simultaneous connections, so that multiple hosts  
can collect data from the same serial device—at the same  
time.  
As illustrated in the figure, data transmission proceeds as  
follows:  
1. The host requests a connection from the NPort  
configured for TCP Server Mode.  
2. Once the connection is established, data can be  
transmitted in both directions—from the host to the  
NPort, and from the NPort to the host.

NPort 5400 Series User’s Manual  
Choosing the Proper Operation Mode  
TCP Client Mode  
In TCP Client mode, NPort can actively establish a  
TCP connection to a pre-defined host computer  
when serial data arrives.  
After the data has been transferred, NPort can  
automatically disconnect from the host computer by  
using the TCP alive check time or Inactivity time  
settings. Refer to chapter 5 for more details.  
As illustrated in the figure, data transmission  
proceeds as follows:  
1. The NPort configured for TCP Client Mode  
requests a connection from the host.  
2. Once the connection is established, data can be  
transmitted in both directions—from the host to  
the NPort, and from the NPort to the host.  
UDP Mode  
Compared to TCP communication, UDP is  
faster and more efficient. In UDP mode, you can  
multicast data from the serial device to multiple  
host computers, and the serial device can also  
receive data from multiple host computers,  
making this mode ideal for message display  
applications.  
Pair Connection Mode  
Pair Connection Mode employs two NPort 5400 in tandem, and can be used to remove the  
15-meter distance limitation imposed by the RS-232 interface. One NPort 5400 is connected from  
its RS-232 port to the COM port of a PC or other type of computer, such as hand-held PDAs that  
have a serial port, and the serial device is connected to the RS-232 port of the other NPort 5400.  
The two NPort 5400 units are then connected to each other with a cross-over Ethernet cable, both  
are connected to the same LAN, or in a more advanced setup, they communicate with each other  
over a WAN (i.e., through one or more routers). Pair Connection Mode transparently transfers  
both data and modem control signals (although it cannot transmit the DCD signal) between the  
two NPorts.

Choosing the Proper Operation Mode  
Reverse Telnet Mode  
Console management is commonly used by connecting to Console/AUX or COM ports of routers,  
switches, and UPS units. Rtelnet works the same as RAW mode in that only one TCP port is  
listened to after booting up. The system then waits for a host on the network to initiate a  
connection. The difference is that the RAW mode does not provide the conversion function  
provided by Telnet. If the connected devices need to use the CR/LF conversion function when  
controlling, then users must choose Rtelnet mode.  
Disabled Mode  
When the Operation Mode for a particular port is set to Disabled, that port will be disabled.

A subnet mask represents all the network hosts at one geographic location, in one building, or on  
the same local area network. When a packet is sent out over the network, the NPort will use the  
subnet mask to check whether the desired TCP/IP host specified in the packet is on local network  
segment. If the address is on the same network segment as the NPort, a connection established  
directly from the NPort. Otherwise, the connection is established through the given default  
gateway.

When the user wants to visit a particular website, the computer asks a Domain Name System  
(DNS) server for the website’s correct IP address, and the computer users the response to connect  
to the web server. DNS is the way that Internet domain names are identified and translated into IP  
addresses. A domain name is an alphanumeric name, such as moxa.com, that it is usually easier to  
remember. A DNS server is a host that translates this kind of text-based domain name into the  
numeric IP address used to establish a TCP/IP connection.  
In order to use NPort’s DNS feature, you need to set the IP address of the DNS server to be able to  
access the host with the domain name. NPort provides DNS server 1 and DNS server 2  
configuration items to configure the IP address of the DNS server. DNS Server 2 is included for  
use when DNS sever 1 is unavailable.  
NPort plays the role of DNS client. Functions that support domain name in NPort are Time Sever  
IP Address, TCP Client-Destination IP Address, Mail Server, SNMP Trap IP Address, and  
IP Location Server.

IP Address Report  
When NPort 5000 series products are used in a dynamic IP environment, users must spend more  
time with IP management tasks. For example, NPort works as a server (TCP or UDP), and the host,  
which acts as a client, must know the IP address of the server. If the DHCP server assigns a new IP  
address to the server, the host must take care of what happens when the IP changes.  
NPort 5000 series products help out by periodically reporting their IP address to the IP location  
server, in case the dynamic IP has changed. The parameters shown below are used to configure the  
Auto IP report function. There are two ways to develop an “Auto IP report Server” to receive

Max Connection  
Setting  
Factory Default  
Necessity  
1, 2, 3, 4  
1
Required  
Max Connection is usually used when the user needs to receive data from different hosts  
simultaneously. The factory default only allows 1 connection at a same. When Max Connection is  
set to 1, the Real COM driver on the specific host has the full control.  
Max. Connection 1:  
Allows only 1 host’s Real COM driver to open the specific NPort serial port.  
Max Connection 2 to 4:  
Allows 2 to 4 host’s Real COM drivers to open the specific NPort serial port, at the same time.  
When multiple hosts’ Real COM drivers open the serial port at the same time, the COM driver  
only provides a pure data tunnel without control ability. That is, this serial port parameter will use  
firmware’s settings, not depend on your application program (AP).  
Application software that is based on the COM driver will receive a driver response of “success”  
when the software uses any of the Win32 API functions. The firmware will only send the data  
back to the driver on the host.  
Data will be sent first-in-first-out when data comes into the NPort from the Ethernet interface.  
ATTENTION  
When Max connection is set to 2, 3, or 4, this means that NPort will be using a “multi connection  
application” (i.e., 2, 3, or 4 hosts are allowed access to the port at the same time). When using a  
multi connection application, NPort will use the serial communication parameters set in the  
console. All of the hosts connected to that port must use the same serial settings. If one of the  
hosts opens the COM port with parameters that are different from NPort’s console setting, data  
communication may not work properly.  
Ignore jammed IP

Factory Default  
Necessity  
No or Yes  
No  
Optional  
Previously, when Max connections > 1, and the serial device is transmitting data, if any one of the

jammed IP,” the host that is not responding will be ignored, but the data will still be transmitted to  
the other hosts.

of the serial data received is greater than 1 KB, the NPort will automatically pack the data and  
send it to the Ethernet. However, to use the delimiter function, you must at least enable Delimiter

Optional  
0: Disable the force transmit timeout.  
1 to 65535: Forces the NPort’s TCP/IP protocol software to try to pack serial data received during  
the specified time into the same data frame.  
This parameter defines the time interval during which NPort fetches the serial data from it’s  
internal buffer. If data is incoming through the serial port, NPort stores the data in the internal  
buffer. NPort transmits data stored in the buffer via TCP/IP, but only if the internal buffer is full or  
if the force transmit time interval reaches the time specified under Force Transmit timeout.  
Optimal force transmit timeout differs according to your application, but it must be at least larger  
than one character interval within the specified baud rate. For example, assume that the serial port  
is set to 1200 bps, 8 data bits, 1 stop bit, and no parity. In this case, the total number of bits needed  
to send a character is 10 bits, and the time required to transfer one character is  
10 (bits) / 1200 (bits/s) * 1000 (ms/s) = 8.3 ms.  
Therefore, you should set Force Transmit timeout to be larger than 8.3 ms. Force Transmit timeout  
is specified in milliseconds and must be larger than 10 ms.

If the user wants to send the series of characters in a packet, the serial device attached to NPort  
should send characters without time delay larger than Force Transmit timeout between characters  
and the total length of data must be smaller than or equal to NPort’s internal buffer size. The serial  
communication buffer size of NPort is 1 Kbytes per port.

7 min  
Optional  
0 min: TCP connection is not closed due to an idle TCP connection.  
1 to 99 min: NPort automatically closes the TCP connection if there is no TCP activity for the  
given time. After the connection is closed, NPort starts listening for another host’s TCP  
connection.  
Inactivity time  
Setting  
Factory Default  
Necessity  
0 to 65535 ms  
0 ms  
Optional  
0 ms: TCP connection is not closed due to an idle serial line.  
0-65535 ms: NPort automatically closes the TCP connection if there is no serial data activity for  
the given time. After the connection is closed, NPort starts listening for another host’s TCP  
connection.  
This parameter defines the maintenances status as Closed or Listen on the TCP connection. The  
connection is closed if there is no incoming or outgoing data through the serial port during the  
specific Inactivity time.  
If the value of inactivity time is set to 0, the current TCP connection is maintained until there is  
connection close request. Although inactivity time is disabled, the NPort will check the connection  
status between the NPort and remote host by sending “keep alive” packets periodically. If the  
remote host does not respond to the packet, it assumes that the connection was closed down  
unintentionally. NPort will then force the existing TCP connection to close.

ATTENTION  
The Inactivity time should at least be set larger than that of Force transmit timeout. To prevent  
the unintended loss of data due to the session being disconnected, it is highly recommended that  
this value is set large enough so that the intended data transfer is completed.  
Max Connection  
Setting  
Factory Default  
Necessity  
1, 2, 3, 4  
1
Required  
Max Connection is usually used when the user needs to receive data from different hosts  
simultaneously. The factory default only allows 1 connection at a time.  
Max. Connection 1:  
NPort only allows 1 host to open the TCP connection to the specific serial port.  
Max Connection 2 to 4:  
Allows 2 to 4 host’s TCP connection request to open the specific NPort serial port, at the same  
time. When multiple hosts establish a TCP connection to the specific serial port at the same time,  
NPort will duplicate the serial data and transmit to all of the hosts. Ethernet data is sent on a  
first-in-first-out basis to the serial port when data comes into NPort from the Ethernet interface.  
Ignore jammed IP  
Setting  
Factory Default  
Necessity  
No or Yes  
No  
Optional  
Previously, when Max connections > 1, and the serial device is transmitting data, if any one of the  
connected hosts is not responding, it will wait until the data has been transmitted successfully  
before transmitting the second group of data to all hosts. Currently, if you select Yes for “Ignore  
jammed IP,” the host that is not responding will be ignored, but the data will still be transmitted to  
the other hosts.  
Allow driver control  
Setting  
Factory Default  
Necessity  
No or Yes  
No  
Optional  
If “max connection” is greater than 1, NPort will ignore driver control commands from all  
connected hosts. However, if you set “Allow driver control” to YES, control commands will be  
accepted. Note that since NPort 5400 may get configuration changes from multiple hosts, the most  
recent command received will take precedence.

Optional  
Once the NPort receives both delimiters through its serial port, it immediately packs all data  
currently in its buffer and sends it to the NPort’s Ethernet port.  
ATTENTION  
Delimiter 2 is optional. If left blank, then Delimiter 1 alone trips clearing of the buffer. If the size  
of the serial data received is greater than 1 KB, the NPort will automatically pack the data and  
send it to the Ethernet. However, to use the delimiter function, you must at least enable Delimiter  
1. If Delimiter 1 is left blank and Delimiter 2 is enabled, the delimiter function will not work  
properly.

Optional  
0: Disable the force transmit timeout.  
1 to 65535: Forces the NPort’s TCP/IP protocol software to try to pack serial data received during  
the specified time into the same data frame.  
This parameter defines the time interval during which NPort fetches the serial data from its  
internal buffer. If there is incoming data through the serial port, NPort stores data in the internal  
buffer. NPort transmits data stored in the buffer via TCP/IP, but only if the internal buffer is full or  
if the force transmit time interval reaches the time specified as Force Transmit timeout.  
Optimal force transmit timeout differs according to your application, but it must be at least as large  
as one character interval within the specified baud rate. For example, assume that the serial port is  
set to 1200 bps, 8 data bits, 1 stop bit, and no parity. In this case, the total number of bits required  
to send a character is 10 bits and the time required to transfer one character is  
10 (bits) / 1200 (bits/s) * 1000 (ms/s) = 8.3 ms.  
Therefore, you should set Force Transmit timeout to be larger than 8.3 ms. Force Transmit timeout

Pair Connection Mode  
Pair Connection Mode employs two NPort 5400 device servers in tandem, and can be used to  
remove the 15-meter distance limitation imposed by the RS-232 interface. One NPort 5400 is  
connected from its RS-232 port to the COM port of a PC or other type of computer, such as  
hand-held PDAs that have a serial port, and the serial device is connected to the RS-232 port of the  
other NPort 5400. The two NPort 5400 device servers are then connected to each other with a  
cross-over Ethernet cable, both are connected to the same LAN, or in a more advanced setup, they  
communicate with each other over a WAN (i.e., through one or more routers). Pair Connection  
Mode transparently transfers both data and modem control signals (although it cannot transmit the  
DCD signal) between the two NPorts.

Cold start  
This refers to starting the system from power off (contrast this with warm start). When performing  
a cold start, NPort will automatically issue an Auto warning message by e-mail, or send an SNMP  
trap after rebooting.  
Warm start  
This refers to restarting the computer without turning the power off. It’s the opposite of cold start.  
When performing a warm start, NPort will automatically send an e-mail, or send an SNMP trap  
after rebooting.  
Authentication failure  
The user inputs a wrong password from the Console or Administrator. When authentication failure  
occurs, NPort will immediately send an e-mail or send an SNMP trap.  
IP address changed  
The user has changed NPort’s IP address. When the IP address changes, NPort will send an e-mail  
with the new IP address before NPort reboots. If the NPort fails to send mail to the mail server  
after 15 seconds, NPort will be rebooting directly and abort the mail auto warning.

DCD changed  
The DCD (Data Carrier Detect) signal has changed, also indicating that the modem connection  
status has changed. For example, a DCD change to high also means “Connected” between local  
modem and remote modem. If the DCD signal changes to low, it also means that the connection  
line is down.  
When the DCD changes, NPort will immediately send an e-mail or send an SNMP trap.  
DSR changed  
The DSR (Data Set Ready) signal has changed, also indicating that the data communication  
equipment’s power is off. For example, a DSR change to high also means that the DCE is powered  
ON. If the DSR signal changes to low, it also means that the DCE is powered off.  
When the DSR changes, NPort will immediately send an e-mail or send an SNMP trap.

Broadcast Search  
The Broadcast Search function is used to locate all NPort 5400s that are connected to the same  
LAN as your computer. Since the Broadcast Search function searches by MAC address and not IP  
address, all NPort 5400s connected to the LAN will be located, regardless of whether or not they  
are part of the same subnet as the host.  
1. Position the cursor in the right middle section of the Administrator window and then click the  
right mouse button.  
2. The Broadcast Search window will open and display the Model, IP Address, MAC Address,  
and Progress of the search for that particular device.  
3. When the search is complete, the Broadcast Search window will close, and the NPort 5400s  
that were located will be displayed in the right pane of the Administrator window. If you  
found more than one server connected to this network, refer to the MAC address sticker on  
your server(s) to determine which server(s) are the ones you wish to configure. To configure  
an NPort 5400, place the cursor over the row displaying that NPort 5400’s information, and  
then double click the left mouse button.

NPort 5400 Series User’s Manual  
Configuring NPort Administrator  
COM Mapping  
Windows Administration Suite comes with Windows 95/98/ME/NT/2000/XP Real COM drivers.  
After you install NPort 5400 Administration Suite, there are two ways to set up the NPort 5400  
serial port as your host’s remote COM port.  
The first way is with On-line COM Mapping. On-line COM Mapping will check to make sure  
that the NPort 5400 is connected correctly to the network, and then install the driver on the host  
computer.  
The second way is with Off-line COM Installation, without first connecting the NPort 5400 to  
the network. Off-line COM Mapping can decrease the system integrator’s effort by solving  
different field problems. Via off-line installation, users can first process software installation for  
the host, and then install the NPort 5400 to different fields.  
Use the following procedure to map COM ports:  
1. On-line COM Mapping:  
Connect NPort 5400 to the network Æ Set NPort 5400 to the proper IP address Æ Map  
COMs to your host Æ Apply Change.  
2. Off-line COM Mapping:  
Map COMs to your host Æ Apply Change Æ Connect NPort 5400 to the network Æ  
Configure NPort 5400’s IP address.  
On-line COM Mapping  
1. Broadcast Search for NPort 5400s on the network.  
2. Select the COM Mapping function group.

4. The NPort 5400 list that appears is the list generated by the previous Broadcast Search. Select  
the NPort 5400 to which you would like to map COM ports.  
5. Select COM Settings to modify COM No., default setting, etc.

NPort 5400 Series User’s Manual  
Configuring NPort Administrator  
6. Select the COM No.  
COM ports that are “In use” or “Assigned” will also be indicated in this drop-down list.  
If you select multiple serial ports or multiple NPort 5400s, remember to check the “Auto  
Enumerating” function to use the COM No. you select as the first COM No.  
7. Hi-performance mode is the default for Tx mode. If the driver completes sending data out to  
the NPort 5400, the driver will respond “Tx Empty” to the program.  
Under classical mode, the driver will not notify the user’s program that Tx is completed until  
all Tx data has been sent out from the NPort 5400. This mode will cause lower throughput. If  
you want to ensure that all data is sent out before further processing, classical mode is  
recommended.  
Enable/Disable Tx/Rx FIFO. If disabled, NPort 5400 will send one byte each time the Tx  
FIFO becomes empty; and an Rx interrupt will be generated for each incoming byte. This will  
result in a faster response and lower throughput. If you want to use XON/XOFF flow control,  
we recommend setting FIFO to Disable.  
Fast Flush (only flush local buffer)  
We have added one optional Fast Flush function to Moxa’s new NPort Real COM driver.  
NPort Administrator Suite for 2G NPort adds it after version 1.2.  
For some applications, the user’s program will use the Win32 “PurgeComm()” function  
before it reads or writes data. With our design, after the program uses this Purge Comm()  
function, the NPort driver will keep querying NPort’s firmware several times to make  
sure there is really no data queued in the NPort firmware buffer, rather than just flushing  
the local buffer. This kind of design is used because of some special considerations.  
However, it might take more time (on the order of several hundred milliseconds) than a  
native COM1, because it needs to work via Ethernet. That’s why the native COM ports  
on the motherboard can work fast with this function call, but NPort requires much more  
time. In order to accommodate other applications that require a faster response time, the  
new NPort driver implements a new “Fast Flush” option. Note that by default, this  
function is disabled.  
To begin with, make sure there are some “PurgeComm()” functions being used in your  
application program. In this kind of situation, you might find that your NPort exhibits a  
much poorer operation performance than when using the native COM1 port. Once you  
have enabled the “Fast Flush” function, you can check to see if there has been an  
improvement in performance.

By default, the optional “Fast Flush” function is disabled. If you would like to enable this  
function, from the “NPort Administrator,” double click on the COM ports that are  
mapped to the NPort, and then select the “Fast Flush” checkbox. You should find that  
when “Fast Flush” is enabled, the NPort driver will work faster with “PurgeComm().”  
8. The Serial Parameter settings shown here are the default settings when the NPort 5400 is  
powered on. However, the program can redefine the serial parameters to different values after  
the program opens the port via Win 32 API.

IP Serial LIB  
Overview  
What is IP Serial Library?  
IP Serial Library is a Windows library with frequently used serial command sets and subroutines.  
IP Serial Library is designed to reduce the complexity and poor efficiency of serial communication  
over TCP/IP. For example, Telnet can only transfer data, but it can't monitor or configure the serial  
line's parameters.  
Why Use IP Serial Library?  
For programmers who are familiar with serial communication, IP Serial Library provides  
well-designed function calls that have the same style as Moxa's PComm Library.  
IP Serial Library is amazingly simple and easy to understand. By including it in your VB, C, or  
Delphi programming environment, you can program your own TCP/IP application with the ability  
to control serial communication parameters.  
NPort Serial Device Servers use 2 TCP ports for communication between the NPort and host  
computer's Real COM driver. NPort uses a data port and command port to provide pure data  
transfer without decode and encode. Compared to using only one TCP port to control serial  
communication (such as RFC 2217), IP Serial Library uses a command port to communicate with  
NPort in user's program. IP Serial Library not only runs with excellent efficiency but also runs  
without any decode or encode problems.  
How to install IP Serial Library?  
IP Serial Lib comes with the NPort Administration Suite. Refer to the IPSerial directory for more  
detail about the function definitions.

Well Known Port Numbers  
This appendix is for your reference about the Well Known port numbers that may cause network  
problem if you set NPort into the same port. Refer to RFC 1700 for Well Known port numbers of  
refer to the following introduction from the IANA.  
The port numbers are divided into three ranges: the Well Known Ports, the Registered Ports, and  
the Dynamic and/or Private Ports.  
The Well Known Ports are those from 0 through 1023.  
The Registered Ports are those from 1024 through 49151.  
The Dynamic and/or Private Ports are those from 49152 through 65535.  
The Well Known Ports are assigned by the IANA, and on most systems, can only be used by  
system processes or by programs executed by privileged users. The following table shows famous  
port numbers among the well-known port numbers. For more details, please visit IANA website:

Auto IP Report Protocol  
NPort Series provides several ways to configure Ethernet IP addresses. One of them is DHCP  
Client. When you set up the NPort to use DHCP Client to configure Ethernet IP addresses, it will  
automatically send a DHCP request over the Ethernet to find the DHCP Server. And then the  
DHCP Server will send an available IP address to the NPort. The NPort will use this IP address for  
a period of time after receiving it. But the NPort will send a DHCP request again to the DHCP  
Server. Once the DHCP Server realizes that this IP address is to be released to other DHCP Client,  
the NPort then will receive a different IP address. For this reason, users sometimes find that the  
NPort will use different IP addresses, not a fixed IP address.  
In order to know what IP address the NPort is using, you need to set up parameters in Network  
Settings via Web browser. The figure below is NPort Web console configuration window. Enter  
the IP address and the Port number of the PC that you want to send this information to.
