Introduction
Overview
The NPort IA5150/5250 series of device servers deliver easy and reliable serial-to-Ethernet
connectivity for the industrial automation market. The NPort IA5150/5250 series is designed to
allow any serial device to connect to an Ethernet network. The compact size of NPort IA device
servers makes them an ideal choice for connecting RS-232/422/485 serial devices, such as PLCs,
sensors, meters, motors, drives, barcode readers, and operator displays. The NPort IA5150/5250
Series device servers come with a compact and rugged DIN-Rail mountable casing.
NPort IA serial device servers ensure the compatibility of network software that uses a standard
network API (Winsock or BSD Sockets) by providing five modes: TCP Server, TCP Client, UDP,
Pair Connection, Ethernet Modem, and Rtelnet. Thanks to NPort IA5150/5250 series’ Real
COM/TTY drivers, software that works with COM/TTY ports can be set up to work over a
TCP/IP network, without modifying the serial COM software applications. This excellent feature
preserves your software investment and lets you enjoy the benefits of networking your serial
devices instantly.
NPort IA serial device servers support automatic IP configuration protocols (DHCP, BOOTP) and
manual configuration via a handy web browser console. Both methods ensure quick and effective
installation. And with NPort IA5150/5250’s Windows Utility, installation is very straightforward,
since all system parameters can be stored and then copied to other device servers simultaneously.

Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your NPort IA5150/5250
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 IA5150/5250. When plugged in, NPort IA5150/5250’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 IA5150/5250’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 IA5150/5250 Series
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.
ATTENTION
This product is intended to be mounted to a well-grounded mounting surface such as a metal
panel.

SG: The Shielded Ground (sometimes called Protected
Ground) contact is the left most contact of the 7-pin power
terminal block connector when viewed from the angle
shown here. Connect the SG wire to an appropriate
grounded metal surface.
Connecting to the Network
Connect one end of the Ethernet cable to NPort IA5150/5250’s 10/100M Ethernet port and the
other end of the cable to the Ethernet network. If the cable is properly connected, NPort
IA5150/5250 will indicate a valid connection to the Ethernet in the following ways:
y

y
The Ethernet LED maintains a solid green color when connected to a 100 Mbps Ethernet
network.
The Ethernet LED maintains a solid orange color when connected to a 10 Mbps Ethernet
network.
The Ethernet LED will flash when Ethernet packets are being transmitted or received.
NPort IA5150 and NPort IA5250 each have 2 Ethernet ports, which can be used to create an
open chain of NPort IA device servers. You must be careful not to connect the Ethernet ports of
the two device servers at the ends of the chain. In other words, NPort IA does NOT support a
closed chain.
NOTE
Connecting to a Serial Device
Connect the serial data cable between NPort IA5150/5250 and the serial device. Serial data cables
are optional accessories for NPort.

Initial IP Address Configuration
When setting up your NPort IA5150/5250 for the first time, the first thing you should do is
configure the IP address. This chapter introduces the methods that can be used to configure the
device server’s IP address. Select one of the initial IP Address configuration methods to
configure NPort IA5150/5250’s IP Address. For more details about network settings, see the
Network Settings section from Chapter 5, Web Console Configuration.
The following topics are covered in this chapter:
‰ Initializing NPort IA5150/5250’s IP Address
‰ Factory Default IP Address
‰ NPort IA5150/5250 Administration Suite
‰ ARP

NPort IA5150/5250 Series User’s Manual
Initial IP Address Configuration
Initializing NPort IA5150/5250’s IP Address
1. Determine whether your NPort IA5150/5250 needs to use a Static IP or Dynamic IP (either
DHCP or BOOTP application).
2. If NPort IA5150/5250 is used in a Static IP environment, you can use NPort IA5150/5250
Administration Suite, ARP, Web Console, Telnet Console, or Serial Console to configure the
new IP address.
3. If NPort IA5150/5250 is used in a Dynamic IP environment, you can use NPort
IA5150/5250 Administration Suite, Web Console, Telnet Console, or Serial Console to
configure NPort IA5150/5250 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
IA5150/5250 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 NPort IA5150/5250.
Factory Default IP Address
NPort IA5150/5250 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 IA5150/5250 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.)
NPort IA5150/5250 Administration Suite
NPort IA5150/5250 Administration Suite consists of some useful utility programs that are used to
configure and manage your NPort IA5150/5250.
See Chapter 5 for details on how to install NPort IA5150/5250 Administration Suite, and
how to use this suite of useful utilities to set up IP addresses and configure your NPort
IA5150/5250 Series serial device servers.
ARP
You can make use of the ARP (Address Resolution Protocol) command to set up an IP address for
your NPort IA5150/5250. The ARP command tells your computer to associate the NPort
IA5150/5250’s MAC address with the intended IP address. You must then use Telnet to access the
NPort IA5150/5250, 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 IA5150/5250 must be
connected to the same LAN. Or, you may use a cross-over Ethernet cable to connect the NPort
IA5150/5250 directly to your computer’s Ethernet card. Before executing the ARP command,
your NPort IA5150/5250 must be configured with the factory default IP address
(192.168.127.254), and your computer and the NPort IA must be on the same subnet.

NPort IA5150/5250 Series User’s Manual
Initial IP Address Configuration
Take the following steps to use ARP to configure the IP address:
1. Obtain a valid IP address for your NPort IA5150/5250 from your network administrator.
2. Obtain NPort IA5150/5250’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 IA5150/5250. (Be sure to use the actual IP address and MAC address
for your NPort IA5150/5250.)
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 IA5150/5250 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 IA5150/5250’s IP address. This can be done using Telnet.
ATTENTION
Figures in this chapter were generated using NPort IA5250.
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.

NPort IA5150/5250 Series User’s Manual
Choosing the Proper Operation Mode
Overview
NPort IA5150/5250 Serial Device Servers network-enable traditional RS-232/422/485 devices, in
which a Serial 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 ports (RS-232/422/485) to collect
data from various kinds of instruments. Since NPort IA5150/5250 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 IA5150/5250 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 IA5150/5250 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 unicast or multicast
of data to only one IP or groups of IP addresses.
Real COM Mode
NPort IA5150/5250 comes equipped with COM
drivers that work with Windows
Real COM Mode
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
IA5150/5250’s serial port to a local COM/TTY
port on the host computer. Real COM Mode also
supports up to 4 simultaneous connections, so that
multiple hosts can collect data from the same
serial device at the same time.

Choosing the Proper Operation Mode
ATTENTION
The driver used for Real COM Mode comes with the NPort IA5150/5250 NPort Administrator.
The driver is installed automatically on your computer when you install NPort IA5150/5250
Administration Suite.
One of the major conveniences of using Real COM Mode 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 IA5150/5250 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
IA5150/5250’s serial ports.
ATTENTION
Real COM Mode allows several hosts to have access control over the same NPort IA5150/5250.
The driver that comes with your NPort IA5150/5250 controls host access to attached serial
devices by checking the host’s IP address. Refer to Accessible IP Settings in Chapter 5 for more
details.
TCP Server Mode
In TCP Server mode, NPort IA5150/5250 is
configured with a unique IP:Port address on a
TCP/IP network. NPort IA5150/5250 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.

TCP Client Mode
In TCP Client mode, NPort IA5150/5250 can
actively establish a TCP connection to a
pre-defined host computer when serial data
arrives.
TCP Client Mode
After the data has been transferred, NPort
IA5150/5250 can automatically disconnect from
the host computer by using the TCP alive check
time or Inactivity time settings. Refer to Chapter

UDP Mode
Compared to TCP communication, UDP is faster
and more efficient. In UDP mode, you can unicast
or multicast data from the serial device to one or
multiple host computers, and the serial device can
also receive data from one or multiple host
computers, making this mode ideal for message
display applications.

Pair Connection Mode
Pair Connection Mode employs two NPort IA5150/5250 in tandem, and can be used to remove the
15-meter distance limitation imposed by the RS-232 interface. One NPort IA5150/5250 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 IA5150/5250. The two NPort IA5150/5250 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
Ethernet Modem Mode
Ethernet Modem Mode is designed for use with legacy operating systems, such as MS-DOS, that do
not support TCP/IP Ethernet. By connecting one of NPort IA5150/5250’s serial port to the MS-DOS
computer’s serial port, it is possible to use legacy software originally designed to transmit data via
modem, but now transmit the data over the Ethernet.
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. In addition, since NPort IA5150/5250’s Rtelnet
mode is widely used in device management in Telecommunication control rooms, managers for
remote hosts can also use a Local User Table or RADIUS to identity verification methods.
Disabled Mode
When the Operation Mode for a particular port is set to Disabled, that port will be disabled.

You must assign a valid IP address to NPort IA5150/5250 before it will work in your network
environment. Your network system administrator should provide you with an IP address and
related settings for your network. The IP address must be unique within the network (otherwise,
NPort IA5150/5250 will not have a valid connection to the network). First time users can refer to
Chapter 3, “Initial IP Address Configuration,” for more information.
You can choose from four possible “IP configuration” modes—Static, DHCP, DHCP/BOOTP,

An IP address is a number assigned to a network device (such as a computer) as a permanent
address on the network. Computers use the IP address to identify and talk to each other over the
network. Choose a proper IP address that is unique and valid in your network environment.
Netmask

Required
A subnet mask represents all of 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
IA5150/5250 will use the subnet mask to check whether the desired TCP/IP host specified in the
packet is on the local network segment. If the address is on the same network segment as the
NPort IA5150/5250, a connection is established directly from the NPort IA5150/5250. Otherwise,
the connection is established through the given default gateway.
Gateway
Setting
Factory Default
Necessity
E.g., 192.168.1.1

Optional
A gateway is a network gateway that acts as an entrance to another network. Usually, the
computers that control traffic within the network or at the local Internet service provider are
gateway nodes. NPort IA5150/5250 needs to know the IP address of the default gateway computer
in order to communicate with the hosts outside the local network environment. For correct
gateway IP address information, consult the network administrator.

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 then the computer uses 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 IA5150/5250’s DNS feature, you need to configure the DNS server. Doing
so allows NPort IA5150/5250 to use a host’s domain name to access the host. NPort IA5150/5250
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 IA5150/5250 plays the role of DNS client, in the sense that the NPort IA5150/5250 will
actively query the DNS server for the IP address associated with a particular domain name. NPort
IA5150/5250 functions that support domain name are Time server, Destination IP Address in
TCP Client mode, Mail Server, SNMP trap server, and Auto report to IP.

to the street address where the NPort IA5150/5250 is physically located.
IP Address Report
When NPort IA5150/5250 Series products are used in a dynamic IP environment, users must
spend more time with IP management tasks. For example, if NPort IA5150/5250 works as a server
(TCP or UDP), then 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 NPort IA5150/5250, the host must have some way of
determining NPort IA5150/5250’s new IP address.
NPort IA5150/5250 Series products help out by reporting their IP address periodically 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 NPort IA5150/5250’s Auto IP report.
1. Use Device Server Administrator’s IP Address Report function.
2. “Auto IP report protocol,” which can receive the Auto IP report automatically on a regular
basis, is also available to help you develop your own software. Refer to Appendix E for the
“Auto IP report protocol.”

1
Required
Max connection is usually used when the user needs to receive data from different hosts
simultaneously. The factory default is 1. In this case, only one specific host can access this port of
the NPort IA5150/5250, and the Real COM driver on that host will have full control over the port.
Max. connection 1:
Allows only 1 host’s Real COM driver to open the specific NPort IA5150/5250 serial port.
Max connection 2 to 4:
Allows 2 to 4 host’s Real COM drivers to open the specific NPort IA5150/5250 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 the firmware settings, instead of depending 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 IA5150/5250 from the Ethernet
interface.

ATTENTION
When Max connection is set to 2, 3, or 4, this means that NPort IA5150/5250 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 IA5150/5250 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 IA5150/5250’s console setting, data communication may not work properly.
Ignore jammed IP

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
Yes or No
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 IA may get configuration changes from multiple hosts, the most
recent command received will take precedence.

0: Disable the force transmit timeout.
1 to 65535: Forces the NPort IA5150/5250’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 IA5150/5250 fetches the serial data
from its internal buffer. If data is incoming through the serial port, NPort IA5150/5250 stores the
data in the internal buffer. NPort IA5150/5250 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.
The optimal Force transmit timeout depends on 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, so in this case, it must
be greater than or equal to 10 ms.
If the user wants to send a series of characters in the same packet, the serial device attached to
NPort IA5150/5250 should send that series of characters during a time interval less than the Force
transmit timeout for NPort IA5150/5250, and the total length of data must be less than or equal to
NPort IA5150/5250’s internal buffer size. The serial communication buffer size for NPort
IA5150/5250 is 1 KB per port.

This parameter defines the maintenance status as Closed or Listen for 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 Inactivity time is set to 0, the current TCP connection is kept active until a connection close
request is received. Although Inactivity time is disabled, the NPort IA5150/5250 will check the
connection status between the NPort IA5150/5250 and remote host by sending “keep alive”
packets periodically. If the remote host does not respond to the packet, NPort IA5150/5250
assumes that the connection was closed down unintentionally. NPort IA5150/5250 will then force
the existing TCP connection to close.

Max. Connection 1:
NPort IA5150/5250 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 this NPort IA5150/5250 serial port, at the
same time. When multiple hosts establish a TCP connection to the specific serial port at the same
time, NPort IA5150/5250 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 IA5150/5250
from the Ethernet interface.

Pair Connection Mode
Pair Connection Mode employs two NPort IA5150/5250 device servers in tandem, and can be
used to remove the 15-meter distance limitation imposed by the RS-232 interface. One NPort
IA5150/5250 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 IA5150/5250. The two NPort IA5150/5250 device servers are then
connected to each other with a cross-over Ethernet cable, both are connected to the same LAN, or

Web Console Configuration
Ethernet Modem Mode
Dial-in
NPort IA5150/5250 listens for a TCP/IP connection request from the remote Ethernet modem or
host. NPort IA5150/5250’s response depends on the ATS0 value, as outlined below.
ATS0=0 (default):
NPort IA5150/5250 will temporarily accept the TCP connection and then send the “RING” signal out
through the serial port. The serial controller must reply with “ATA” within 2.5 seconds to accept the
connection request, after which NPort IA5150/5250 enters data mode. If no “ATA” command is received,
NPort IA5150/5250 will disconnect after sending three “RING” signals.
ATS0≧1:
NPort IA5150/5250 will accept the TCP connection immediately and then send the “CONNECT
<baud>” command to the serial port, in which <baud> represents the baud rate of NPort
IA5150/5250’s serial port. After that, NPort IA5150/5250 immediately enters data mode.
Dial-out
NPort IA5150/5250 accepts the AT command “ATD <IP>:<TCP port>” from the serial port and
then requests a TCP connection from the remote Ethernet Modem or PC. This is where <IP> is the
IP address of the remote Ethernet modem or PC, and <TCP port> is the TCP port number of the
remote Ethernet modem or PC. Once the remote unit accepts this TCP connection, NPort
IA5150/5250 will send out the “CONNECT <baud>” signal via the serial port and then enter data
mode.
Disconnection request from local site
When NPort IA5150/5250s is in data mode, the user can drive the DTR signal to OFF, or send
“+++” from the local serial port to NPort IA5150/5250. NPort IA5150/5250 will enter command
mode and return “NO CARRIER” via the serial port, and then input “ATH” to shut down the TCP
connection after 1 second.
The “+++” command cannot be divided. The “+” character can be changed in register S2, and the
guard time, which prefixes and suffixes the “+++” in order to protect the raw data, can be changed
in register S12.
NOTE
Disconnection request from remote site
After the TCP connection has been shut down by the remote Ethernet modem or PC, NPort
IA5150/5250 will send the “NO CARRIER” signal via the serial port and then return to command
mode.
The following tables give the additional parameters that can be configured for TCP Client Mode.
Refer to the table below the figures to see details of the meaning of each parameter.

Power failure
We provide two DC power inputs for redundancy. NPort IA supports different approaches to warn
engineers automatically, such as by email or relay output (which closes the circuit). Users can
connect to Monitor Æ Relay Output from the web console to check what event causes the warning.
The relay output will be canceled after the power recovers, or by selecting “acknowledge event”
using the web console or Telnet.
When the Relay Output is sending a warning, the Ready LED will flash red until the warning
event ceases.
Ethernet1 link down
NPort IA can provide system maintainers with real-time alarm messages. Even when control
engineers are out of the control room for an extended period of time, they can still be informed of
the status of devices almost instantaneously when exceptions occur. NPort IA supports different
methods for warning engineers automatically, such as by email, SNMP trap, and relay output
(which closes the circuit). Users can connect to Monitor Æ Relay Output from the web console to
check which event is causing the warning. The relay output will be canceled if Ethernet link 1 is
restored, or by selecting “acknowledge event” from the web console or Telnet.
When the Relay Output is issuing a warning, the Ready LED will flash in red until the warning
event ceases.

COM Mapping
Windows Administration Suite comes with Windows 95/98/ME/NT/2000/XP Real COM drivers.
After you install NPort IA5150/5250 Administration Suite, there are two ways to set up the NPort
IA5150/5250 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 IA5150/5250 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
IA5150/5250 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 IA5150/5250 to different fields.
Use the following procedure to map COM ports:
1. On-line COM Mapping:
Connect NPort IA5150/5250 to the network Æ Set NPort IA5150/5250 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 IA5150/5250 to the network Æ
Configure NPort IA5150/5250’s IP address.
On-line COM Mapping
1. Broadcast Search for NPort IA5150/5250s on the network.
2. Select the COM Mapping function group.

4. The NPort IA5150/5250 list that appears is the list generated by the previous Broadcast
Search. Select the NPort IA5150/5250 to which you would like to map COM ports.
5. Select COM Settings to modify COM No., default setting, etc.

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 IA5150/5250s, 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 IA5150/5250, 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 IA5150/5250; 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 IA5150/5250 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 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()

NPort IA5150/5250 Series User’s Manual
Configuring NPort Administrator
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
IA5150/5250 is powered on. However, the program can redefine the serial parameters to
different values after the program opens the port via Win 32 API.

9. After setting the COM Mapping, remember to select Apply Change to save the information
in the host system registry. The host computer will not have the ability to use the COM port
until after Apply Change is selected.

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 IA5150/5250 uses 2 TCP ports for communication between the NPort IA5150/5250 and
host computer’s Real COM driver. NPort IA5150/5250 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 IA5150/5250 from the 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 IA5150/5250 Administration Suite. Refer to the IPSerial
directory for more details about the function definitions.

Auto IP Report Protocol
NPort Series provides several ways to configure Ethernet IP addresses. One is DHCP Client.
When you set up 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 Clients,
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 which IP address the NPort is using, you need to set up parameters in Network
Settings via Web browser. The figure below shows the NPort Web console configuration window.
Enter the IP address and the Port number of the PC that you want to send this information to.
