Connecting the Hardware
This section describes how to connect the NPort 5100A to serial devices for first time testing purposes. We
cover Connecting to the Network, Connecting to a Serial Device, and LED Indicators.
Connecting the Power
NPort P5150A: Connect the Ethernet to a PoE switch. The P5150A will receive power from the PoE Switch.
NPort 5150A/5130A/5150A: Connect the 12 to 48 VDC power code with NPort 5100A’s power input. 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.
Connecting to the Network
Connect one end of the Ethernet cable to NPort 5100A’s 10/100M Ethernet port and the other end of the cable
to the Ethernet network. NPort 5100A will indicate a valid connection to the Ethernet in the following ways:
•
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.

NPort 5100A Series Users Manual
•
Getting Started
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 5100A and the serial device. NPort 5100A’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 5100A has 3 LED indicators, as described in the following table.

Adjustable Pull High/Low 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 5150A/5130A uses jumpers and the NPort P5150A uses dip switches to set the pull high/low resistor
values for each serial port.
2-4
NPort 5100A Series Users Manual
Getting Started
NPort 5150A/5130A Jumpers
To set a pull high/low resistor to 150 KΩ, make sure that the two jumpers (JP3 and JP4) assigned to the
serial port are not shorted by jumper caps. This is the default setting.
To set a pull high/low resistor to 1 KΩ, make sure that the two jumpers (JP3 and JP4) assigned to the serial
port are shorted by jumper caps.

Initial IP Address Configuration
When setting up your NPort 5100A for the first time, you should first configure the IP address. This chapter
introduces the method to configure the device server’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 the NPort 5100A’s IP Address
 Factory Default IP Address
 NPort Administration Suite
 ARP
 Telnet Console
 Serial Console (19200, n, 8, 1) (NPort 5110A/5150A/P5150A only)
NPort 5100A Series Users Manual
Initial IP Address Configuration
Initializing the NPort 5100A’s IP Address
1. Determine whether your NPort 5100A needs to use a Static IP or Dynamic IP (either DHCP or BOOTP
application).
2. If the NPort 5100A is used in a Static IP environment, you can use NPort Administration Suite, ARP, Web
Console, Telnet Console, or Serial Console to configure the new IP address.
3. If the NPort 5100A is used in a Dynamic IP environment, you can use NPort Administration suite, Web
Console, Telnet Console, or Serial Console to configure the NPort 5100A 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 5100A 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 5100A.
Factory Default IP Address
NPort 5100A 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 5100A 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 Administration Suite
NPort Administration Suite consists of useful utility programs that are used to configure and manage your NPort
5100As.
See Chapter 6 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 5100A serial device servers.
ARP
You can make use of the ARP (Address Resolution Protocol) command to set up an IP address for your NPort
5100A. The ARP command tells your computer to associate the NPort 5100A’s MAC address with the intended
IP address. You must then use Telnet to access the NPort 5100A, 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 5100A must be connected to the same
LAN. Or, you may use a cross-over Ethernet cable to connect the NPort 5100A directly to your computer’s
Ethernet card. Your NPort 5100A must be configured with the factory default IP address—192.168.127.254—
before executing the ARP command, as described below.
Take the following steps to use ARP to configure the IP address:
1. Obtain a valid IP address for your NPort 5100A from your network administrator.
2. Obtain the NPort 5100A’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:
3-2
NPort 5100A Series Users Manual
Initial IP Address Configuration
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 5100A (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 5100A
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 5100A’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 5100A is password protected.
4. Type 2 to select Network settings, and then press Enter.
3-3

5. Type 1 to select IP address and then press Enter.
6. Use the Backspace key to erase the current IP address, type in the new IP address, and then press Enter.
7. Press any key to continue.
8. Type m and then press Enter to return to the main menu.
3-4

Initial IP Address Configuration
9. Type s and then press Enter to Save/Restart the system.
10. Type y and then press Enter to save the new IP address and restart the NPort 5100A.
Serial Console (19200, n, 8, 1) (NPort
5110A/5150A/P5150A only)
You may use the RS-232 console port to set up the IP address for NPort 5100A. We suggest using PComm
Terminal Emulator, which is available free of charge as part of the PComm Lite program suite (found on the
Software CD that comes with the product), to carry out the installation procedure, although other similar
utilities may also be used.
Before you start to configure the NPort 5100A via serial console, turn off the power and connect the serial cable
from NPort 5100A to your computer’s serial port.

Choosing the Proper Operation Mode
Overview
NPort 5100A 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 5100A 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 5100A 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 5100A 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 5100A comes equipped with COM drivers that work
with Windows 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 5100A’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 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 5100A accepts the Ethernet
4-2
NPort 5100A Series Users Manual
Choosing the Proper Operation Mode
frame, unpacks the TCP/IP packet, and then sends it transparently sends it to the appropriate serial device
attached to one of the NPort 5100A’s serial ports.
ATTENTION
Real COM Mode allows several hosts to have access control to the same NPort 5100A. The driver that comes
with your NPort 5100A 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.
RFC 2217 Mode
RFC 2217 mode is similar to Real COM mode in that a driver is used to establish a transparent connection
between a host computer and a serial device by mapping the serial port on the NPort 5100A to a local COM port
on the host computer. RFC 2217 defines general COM port control options based on the Telnet protocol. Third
party drivers supporting RFC 2217 are widely available on the Internet and can be used to implement Virtual
COM mapping to your NPort 5100A serial port(s).
TCP Server Mode
In TCP Server Mode, NPort 5100A is configured with a unique
IP:Port combination on a TCP/IP network. In this case, NPort
5100A 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 5100A
configured for TCP Server Mode.
2. Once the connection is established, data can be
transmitted in both directions—from the host to the NPort
5100A, and from the NPort 5100A to the host.
4-3
NPort 5100A Series Users Manual
Choosing the Proper Operation Mode
TCP Client Mode
In TCP Client Mode, the NPort 5100A can actively establish
a TCP connection with a pre-determined host computer
when serial data arrives.
After the data has been transferred, the NPort 5100A 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:
The NPort 5100A 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 5100A, and
from the NPort 5100A 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 5100A in tandem, and can be used to remove the 15-meter distance
limitation imposed by the RS-232 interface. One NPort 5100A 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 5100A. The two NPort 5100A 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
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 5100A’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.

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 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 Reverse Telnet 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 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 5100A 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 5100A, a connection is established directly from the NPort 5100A.
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 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 the NPort 5100A’s DNS feature, you need to configure the DNS server. Doing so allows the NPort
5100A to use a host’s domain name to access the host. The NPort 5100A 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.
The NPort 5100A plays the role of DNS client, in the sense that the NPort 5100A will actively query the DNS
server for the IP address associated with a particular domain name. The NPort 5100A 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 5100A products are used in a dynamic IP environment, users must spend more time with IP
management tasks. For example, if NPort 5100A 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 5100A,
the host must have some way of determining NPort 5100A’s new IP address.
NPort 5100A 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 5100A’s Auto IP report.
Use Device Server Administrator’s IP Address Report function.

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 5100A, 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 5100A serial port.
Max Connection 2 to 8:
Allows 2 to 8 host’s Real COM drivers to open the specific NPort 5100A 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 5100A from the Ethernet interface.

NPort 5100A Series Users Manual
Web Console Configuration
ATTENTION
When Max connection > 1, this means that the NPort 5100A will be using a “multi connection application” (i.e.,
2 or more hosts are allowed access to the port at the same time). When using a multi connection application,
the NPort 5100A 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 5100A’s console setting, data communication may not work properly.
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
5100A may get configuration changes from multiple hosts, the most recent command received will take
precedence.

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

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 a value larger than 8.3 ms, so in this case, it must be
greater than or equal to 10 ms.

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 5100A will check the connection status between the
NPort 5100A and remote host by sending “keep alive” packets periodically. If the remote host does not respond
to the packet, NPort 5100A assumes that the connection was closed down unintentionally. NPort 5100A 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 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 8:
Allows 2 to 8 host’s TCP connection request to open this NPort 5100A serial port, at the same time. When
multiple hosts establish a TCP connection to the specific serial port at the same time, NPort 5100A 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 5100A from the Ethernet interface.

UDP Multicast
A multicast is a packet sent by one host to multiple hosts. In multicast, each host that belongs to a specific
multicast group will receive multicast packets for that group. To configure a host as a multicast receiver over
the Internet, it must inform the routers on its LAN. The Internet Group Management Protocol (IGMP) is used to
communicate group membership information between hosts and routers on a LAN. NPort 5100A supports IGMP
version 2.
You could key in the IP (ex. 239.1.1.1) that multicast group assigned into the column of Destination IP address,
and next, NPort would automatically add the Group, receiving all packets from this group in order to fulfill the
function of multicast.

the serial port. The serial controller must reply with “ATA” within 2.5 seconds to accept the connection
request, after which NPort 5100A enters data mode. If no “ATA” command is received, NPort 5100A will
disconnect after sending three “RING” signals.

NPort 5100A Series Users Manual

ATS0≧1:
NPort 5100A 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 5100A’s serial port. After
that, NPort 5100A immediately enters data mode.
Dial-out
NPort 5100A 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 5100A will send out the “CONNECT <baud>” signal via the serial port
and then enter data mode.
Disconnection request from local site
When NPort 5100As is in data mode, the user can drive the DTR signal to OFF, or send “+++” from the local
serial port to NPort 5100A. NPort 5100A 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 5100A will send the
“NO CARRIER” signal via the serial port and then return to command mode.

COM Mapping
Windows Administration Suite comes with Windows 95/98/ME/NT/2000/XP/7 Real COM drivers. After you
install NPort Administration Suite, there are two ways to set up the NPort 5100A 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
5100A 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 5100A 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 5100A
to different fields.
Use the following procedure to map COM ports:
1. On-line COM Mapping:
Connect NPort 5100A to the network  Set NPort 5100A to the proper IP address  Map COMs to your host
 Apply Change.
2. Off-line COM Mapping:
Map COMs to your host  Apply Change  Connect the NPort 5100A to the network  Configure NPort
5100A’s IP address.
On-line COM Mapping
1. Broadcast Search for NPort 5100As on the network.
2. Select the COM Mapping function group.
3. Add the target to which you would like to map COM ports.
4. The NPort 5100A list that appears is the list generated by the previous Broadcast Search. Select the NPort
5100A to which you would like to map COM ports.
6-15
NPort 5100A Series Users Manual
Configuring NPort Administrator
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 5100As, 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
5100A, 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 5100A; 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 5100A 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 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 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.
6-16
NPort 5100A Series Users Manual
Configuring NPort Administrator
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().”
8. The Serial Parameter settings shown here are the default settings when the NPort 5100A 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.

COM Grouping
The “COM Grouping” function is designed to simulate the multi-drop behavior of serial communication over an
Ethernet network. COM Grouping allows you to create a COM Group and redirect data from it to several physical
COM ports on NPort device servers. With COM Grouping, you will be able to control multiple physical serial ports
simultaneously by operating only one COM port.
Creating a COM Group
Follow the steps below to add multiple COM ports into one group:
1. Select serial port(s) for the group that you are going to create, and right-click to select COM Settings.
2. Select a COM number for this COM group. You may select one of the ports already assigned to a member
of the COM Group. However, once the COM Group is configured, all of the original COM number(s) within the
group will be released simultaneously.
ATTENTION
The COM Grouping function only supports Windows NT, 2000, and later. The maximum number of ports for
each group is 32.

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 5100A uses 2 TCP ports for communication between the NPort 5100A and host computer’s Real COM
driver. NPort 5100A 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 5100A 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 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 5100A 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

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.
