NPort 5100 Series User’s Manual
Getting Started
Connecting to the Network
Connect one end of the Ethernet cable to NPort 5100’s 10/100M Ethernet port and the other end of
the cable to the Ethernet network. NPort 5100 will indicate a valid connection to the Ethernet in
the following ways:
y The Ethernet LED maintains a solid green color when connected to a 100 Mbps Ethernet
network.
y The Ethernet LED maintains a solid orange color when connected to a 10 Mbps Ethernet
network.
y The Ethernet LED will flash when Ethernet packets are being transmitted or received.
Connecting to a Serial Device
Connect the serial data cable between NPort 5100 and the serial device. NPort 5100’s serial port
uses the RS-232/422/485 interface to transmit data. The port uses a standard male DB9 pin
assignment. Refer to Appendix A to see the signal definitions for the port.
LED Indicators
NPort 5100 has 3 LED indicators, as described in the following table.

Adjustable Termination Resistor for RS-485 Port
In some critical environments, you may need to add termination resistors to prevent the reflection
of serial signals. When using termination resistors, it is important to set the pull high/low resistors
correctly so that the electrical signal is not corrupted. Since a particular pull high/low resistor
value cannot fit all environments, the NPort 5150/5130 uses jumpers to set the pull high/low
resistor values for each serial port.
To set a termination resistor to 150 KΩ, make sure both of the assigned jumpers are in the OFF
position. This is the default setting.
To set a termination resistor to 1 KΩ, make sure both of the assigned jumpers are in the ON
position.
2-3
NPort 5100 Series User’s Manual
Getting Started
ATTENTION
Do not use the 1 KΩ setting on the NPort 5150/5130 when using the RS-232 interface. Doing so
will degrade the RS-232 signals and shorten the maximum allowed communication distance.

Initial IP Address Configuration
Initializing the NPort 5100’s IP Address
1.
Determine whether your NPort 5100 needs to use a Static IP or Dynamic IP (either DHCP or
BOOTP application).
2.
If the NPort 5100 is used in a Static IP environment, you can use NPort 5100 Administration
Suite, ARP, Web Console, Telnet Console, or Serial Console to configure the new IP address.
3.
If the NPort 5100 is used in a Dynamic IP environment, you can use NPort 5100
Administration suite, Web Console, Telnet Console, or Serial Console to configure the NPort
5100 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 5100 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 5100.
Factory Default IP Address
NPort 5100 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 access a device configured with a private IP address directly from a public network.
For example, you would not be able to ping such a device from an outside Internet connection.
NPort 5100 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 5100 Administration Suite
NPort 5100 Administration Suite consists of useful utility programs that are used to configure and
manage your NPort 5100s.
See Chapter 5 for details on how to install NPort 5100 Administration Suite, and how to use
this suite of useful utilities to set up IP addresses and configure your NPort 5100 serial device
servers.
ARP
You can make use of the ARP (Address Resolution Protocol) command to set up an IP address for
your NPort 5100. The ARP command tells your computer to associate the NPort 5100’s MAC
address with the intended IP address. You must then use Telnet to access the NPort 5100, at which
point the device server’s IP address will be reconfigured.
ATTENTION
In order to use this setup method, both your computer and the NPort 5100 must be connected to
the same LAN. Or, you may use a cross-over Ethernet cable to connect the NPort 5100 directly
to your computer’s Ethernet card. Your NPort 5100 must be configured with the factory default
IP address—192.168.127.254—before executing the ARP command, as described below.
3-2
NPort 5100 Series User’s Manual
Initial IP Address Configuration
Take the following steps to use ARP to configure the IP address:
1.
2.
3.
Obtain a valid IP address for your NPort 5100 from your network administrator.
Obtain the NPort 5100’s MAC address from the label on its bottom panel.
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 5100 (be sure to use the numbers determined in steps 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 5100 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 5100’s IP address. This can be done using the Telnet.
1.
From the Windows desktop, click 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 5100 is
password protected.

Choosing the Proper Operation Mode
Overview
NPort 5100 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 5100 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.
The NPort 5100 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, the NPort 5100 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 data to be unicast to
only one IP address, or multicast to groups of IP addresses.
Real COM Mode
The NPort 5100 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 5100’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.
ATTENTION
The driver used for Real COM Mode is bundled with NPort Administrator. The driver is
installed on your computer automatically when you install NPort 5100 Administration Suite.

NPort 5100 Series User’s Manual
Choosing the Proper Operation Mode
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 5100 accepts the Ethernet frame, unpacks the TCP/IP packet, and then sends
it transparently sends it to the appropriate serial device attached to one of the NPort 5100’s serial
ports.
ATTENTION
Real COM Mode allows several hosts to have access control to the same NPort 5100. The driver
that comes with your NPort 5100 controls host access to attached serial devices by checking the
host’s IP address. Refer to the Accessible IP Settings section of Chapter 5 for more details.
TCP Server Mode
In TCP Server Mode, NPort 5100 is configured
with a unique IP:Port combination on a TCP/IP
network. In this case, NPort 5100 waits passively
to be contacted by the host computer. After the
host computer establishes a connection with the
serial device, it can then proceed with data
transmission. TCP Server 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 5100 configured for TCP Server Mode.
2.
Once the connection is established, data can
be transmitted in both directions—from the
host to the NPort 5100, and from the NPort
5100 to the host.

Choosing the Proper Operation Mode
TCP Client Mode
In TCP Client Mode, the NPort 5100 can
actively establish a TCP connection with a
pre-determined host computer when serial data
arrives.
After the data has been transferred, the NPort
5100 can disconnect automatically from the host
computer by using the TCP alive check time or
Inactivity time settings. Refer to Chapter 5 for
detailed configuration instructions.
As illustrated in the figure, data transmission
proceeds as follows:
1.
2.
The NPort 5100 configured for TCP Client
Mode requests a connection from the host.
Once the connection is established, data can
be transmitted in both directions—from the
host to the NPort 5100, and from the NPort
5100 to the host.
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 5100 in tandem, and can be used to remove the
15-meter distance limitation imposed by the RS-232/422/485 interface. One NPort 5100 is
connected from its RS-232/422/485 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-232/422/485 port of the other NPort 5100. The two NPort 5100 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.

NPort 5100 Series User’s Manual
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 5100’s serial ports 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 TCP Server 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 TCP Server 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.

You must assign a valid IP address to the NPort 5100 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,
the NPort 5100 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,

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 5100 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 5100, a
connection is established directly from the NPort 5100. Otherwise, the connection is established
through the given default gateway.
Gateway

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 5100 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 5100’s DNS feature, you need to configure the DNS server. Doing so allows
NPort 5100 to use a host’s domain name to access the host. NPort 5100 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 5100 plays the role of DNS client, in the sense that the NPort 5100 will actively query the
DNS server for the IP address associated with a particular domain name. NPort 5100 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.

IP Address Report
When NPort 5100 products are used in a dynamic IP environment, users must spend more time
with IP management tasks. For example, if NPort 5100 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 5100, the host must have some way of determining NPort 5100’s new IP
address.
NPort 5100 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 NPort 5100’s
Auto IP report.

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 5100, 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 5100 serial port.
Max Connection 2 to 4:
Allows 2 to 4 host’s Real COM drivers to open the specific NPort 5100 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’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 5100 from the Ethernet
interface.

ATTENTION
When Max connection is set to 2, 3, or 4, this means that the NPort 5100 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, the NPort 5100 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 the
NPort 5100’s console setting, data communication may not work properly.

Factory Default
Necessity
0 ms
Optional
1 to 65535: Forces the NPort 5100’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 5100 fetches the serial data from its
internal buffer. If data is incoming through the serial port, NPort 5100 stores the data in the
internal buffer. NPort 5100 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 baudrate. 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 5100 should send that series of characters during a time interval less than the Force transmit
timeout for NPort 5100, and the total length of data must be less than or equal to NPort 5100’s
internal buffer size. The serial communication buffer size for NPort 5100 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 5100 will check the connection
status between the NPort 5100 and remote host by sending “keep alive” packets periodically. If the
remote host does not respond to the packet, NPort 5100 assumes that the connection was closed
down unintentionally. NPort 5100 will then force the existing TCP connection to close.
5-13
NPort 5100 Series User’s Manual

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.

of the serial data received is greater than 1 KB, the NPort 5100 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.

0 ms
Optional
1 to 65535: Forces the NPort 5100’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 5100 fetches the serial data from its
internal buffer. If data is incoming through the serial port, NPort 5100 stores the data in the
internal buffer. NPort 5100 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 baudrate. 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 5100 should send that series of characters during a time interval less than the Force transmit
timeout for NPort 5100, and the total length of data must be less than or equal to NPort 5100’s
internal buffer size. The serial communication buffer size for NPort 5100 is 1 KB per port.

Necessity
Optional
0-65535 ms: NPort 5100 automatically closes the TCP connection if there is no serial data activity
for the given time.
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 5100 will check the connection
status between the NPort 5100 and remote host by sending “keep alive” packets periodically. If the
remote host does not respond to the packet, NPort 5100 assumes that the connection was closed
down unintentionally. NPort 5100 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.
ATTENTION
Inactivity time is ONLY active when “TCP connect on” is set to “Any character.”

Optional
Previously, when Max connections > 1, and the serial device is transmitting data, if any one of the

Pair Connection Mode
Pair Connection Mode employs two NPort 5100 device servers in tandem, and can be used to
remove the 15-meter distance limitation imposed by the RS-232/422/485 interface. One NPort
5100 is connected from its RS-232/422/485 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-232/422/485 port of the other NPort 5100. The two NPort 5100 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.

Ethernet Modem Mode
Dial-in
NPort 5100 listens for a TCP/IP connection request from the remote Ethernet modem or host.
NPort 5100’s response depends on the ATS0 value, as outlined below.
ATS0=0 (default):
NPort 5100 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 5100 enters data mode. If no “ATA” command is
received, NPort 5100 will disconnect after sending three “RING” signals.
ATS0≧1:
NPort 5100 will accept the TCP connection immediately and then send the “CONNECT <baud>”
command to the serial port, in which <baud> represents the baudrate of NPort 5100’s serial port.
After that, NPort 5100 immediately enters data mode.
Dial-out
NPort 5100 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 5100
will send out the “CONNECT <baud>” signal via the serial port and then enter data mode.
Disconnection request from local site
When NPort 5100s is in data mode, the user can drive the DTR signal to OFF, or send “+++” from
the local serial port to NPort 5100. NPort 5100 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.
NOTE
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.
Disconnection request from remote site
After the TCP connection has been shut down by the remote Ethernet modem or PC, NPort 5100
will send the “NO CARRIER” signal via the serial port and then return to command mode.

Accessible IP Settings
The NPort 5100 uses an IP address based filtering method to control access to itself.
Accessible IP Settings allows you to add or block remote host IP addresses to prevent
unauthorized access. Access to NPort 5100 is controlled by IP address. That is, if a host’s IP
address is in the accessible IP table, then the host will be allowed to access the NPort 5100. You
can allow one of the following cases by setting the parameter.
• Only one host with a specific IP address can access the NPort 5100
Enter “IP address/255.255.255.255” (e.g., “192.168.1.1/255.255.255.255”).

Cold start
This refers to starting the system from power off (contrast this with warm start). When performing
a cold start, NPort 5100 will automatically issue an Auto warning message by e-mail, or send an
SNMP trap after booting up.
Warm start
This refers to restarting the computer without turning the power off. When performing a warm
start, NPort 5100 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, the NPort will immediately send an e-mail or send an SNMP trap.
IP address changed
The user has changed NPort 5100’s IP address. When the IP address changes, NPort 5100 will
send an e-mail with the new IP address before NPort 5100 reboots. If the NPort 5100 is unable to
send an e-mail message to the mail server within 15 seconds, NPort 5100 will reboot anyway, and
abort the e-mail auto warning.
Password changed
The user has changed NPort 5100’s password. When the password changes, NPort 5100 will send
an e-mail with the password changed notice before NPort 5100 reboots. If the NPort 5100 is
unable to send an e-mail message to the mail server within 15 seconds, NPort 5100 will reboot

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.

COM Mapping
Windows Administration Suite comes with Windows 95/98/ME/NT/2000/XP Real COM drivers.
After you install NPort 5100 Administration Suite, there are two ways to set up the NPort 5100
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 5100 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 5100 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 5100 to different fields.
Use the following procedure to map COM ports:
1.
On-line COM Mapping:
Connect NPort 5100 to the network Æ Set NPort 5100 to the proper IP address Æ Map
COMs to your host Æ Apply Change.

5.
Select COM Settings to modify COM No., default setting, etc.
6.
Select the COM Number.
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 5100s, 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 5100, 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 5100; 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, the NPort 5100 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()
6-20
NPort 5100 Series User’s Manual
Configuring NPort Administrator
function, the NPort driver will keep querying the 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 the 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 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().”

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 5100 uses 2 TCP ports for communication between the NPort 5100 and host computer’s
Real COM driver. NPort 5100 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 5100 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 5100 Administration Suite. Refer to the IPSerial directory for
more detail about the function definitions.

Well Known Port Numbers
In this appendix, which is included for your reference, we provide a list of Well Known port
numbers that may cause network problems if you set NPort 5100 to one of these ports. Refer to
RFC 1700 for Well Known port numbers, or 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 range from 0 through 1023.
The Registered Ports range from 1024 through 49151.
The Dynamic and/or Private Ports range 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 the IANA
website at http://www.iana.org/assignments/port-numbers.

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 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.
