Overview
The NPort 5600 Series serial device servers are designed to make your industrial serial devices
Internet ready instantly. The compact size of the NPort 5600 device servers makes them the ideal
choice for connecting your RS-232 (NPort 5610-16/8), RS-422 /485 (NPort 5630-16/8), or
RS-232/422/485 (NPort 5650-16/8) serial devices—such as PLCs, meters, and sensors—to an
IP-based Ethernet LAN, making it possible for your software to access serial devices anywhere
over a local LAN or the Internet.
The NPort 5600 serial device servers ensure the compatibility of network software that uses a
standard network API (Winsock or BSD Sockets) by providing TCP Server Mode, TCP Client
Mode, and UDP Mode. And thanks to NPort’s Real COM/TTY drivers, software that works with
COM/TTY ports can be set up to work over a TCP/IP network in no time. This excellent feature
preserves your software investment and lets you enjoy the benefits of networking your serial
devices instantly.
The NPort 5600 serial device servers support automatic IP configuration protocols (DHCP,
BOOTP) and manual configuration via NPort ’ s han dy web browser console. Both methods ensure
quick and effective installation, and by using NPort 5600’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 5600 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 5600. When plugged in, NPort 5600’s internal
components generate heat, and consequently the casing may feel hot to the touch.
You should also pay attention to the following points:
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.
y 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 Keep input wiring and output wirin g separate.
y Where necessary, it is strongly advised that you label wiring to all devices in the system.
Connecting NPort 5610/30/50-16/8’s Power
Connect NPort 5610/30-16/8’s 100-240 VAC power line with its AC connector. 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 NPort 5610-16/8-48V’s Power
To connect NPort 5610-16/8-48V’s power cord with its terminal block, follow the steps given
below:
2-3
NPort 5600 Series User’s Manual Initial IP Address Configuration
1. Loosen the screws on the V

You should use 8 kg-cm of screw torque and 22-14 AWG of suitable electric wire to connect
NPort 5610-16/8-48V’s power cord to its terminal block.
Grounding NPort 5610-16/8-48V
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.

Connecting to the Network
Connect one end of the Ethernet cable to NPort 5600’s 10/100M Ethernet port and the other end of
the cable to the Ethernet network. There are 2 LED indicators located on the bottom left and right
corners of the Ethernet connector. If the cable is properly connected, NPort 5600 will indicate a
valid connection to the Ethernet in the following ways:
The bottom right corner LED indicator maintains a solid green color when the
cable is properly connected to a 100 Mbps Ethernet network.
The bottom left corner LED indicator maintains a solid orange color when the
cable is properly connected to a 10 Mbps Ethernet network.

Real Time Clock
NPort 5600’s real time clock is powered by a lithium battery. We strongly recommend that you do
not replace the lithium battery without the presence of MOXA’s technical support engineers. If
you need a battery change, contact MOXA for assistance.
ATTENTION
There is risk of explosion if the battery is replaced by an incorrect type. You need to dispose
used batteries according to the instructions.
Adjustable Termination Resistor for the RS-485 Port
In some critical environments, you may need to add termination resistors to prevent the reflection
of serial signals. When using terminat i on res i st or s, 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 5650 uses DIP switches to set the pull high/low
resistor values for each serial port.
2-5
NPort 5600 Series User’s Manual Initial IP Address Configuration
To set a termination resistor to 150 KΩ, make sure both of the assigned DIP switches are in the
OFF position. This is the default setting.
To set a termination resistor to 1 KΩ, make sure both of the assigned DIP switches are in the ON
position.
ATTENTION
Do not use the 1 KΩ setting on the NPort 5650 when using the RS-232 interface. Doing so will
degrade the RS-232 signals and shorten the maximum allowed communication distance.

Chapter 3 Initial IP Address Configuration
When setting up your NPort 5600 for the first time, the first thing you should do is configure the
IP address. This chapter introduces several methods to configure NPort’s IP address. Select the
method that is the most convenient for you. For more details about network settings, see the
Network Settings section from Chapter 5, Web Console Configuration.
This chapter includes the following sections:

LCM Display Å recommended configuration method
NPort Administration Suite Å recommended configuration method
ARP
Telnet Console
NPort 5600 Series User’s Manual Choosing the Proper Operation Mode
Initializing NPort’s IP Address
1. Determine whether your NPort needs to use a Static IP or Dynamic IP (either DHCP or
BOOTP application).
2. If NPort is used in a Static IP environment, you can use NPort Administration Suite , A R P,
Web Console, or Telnet Console to configure the new IP address.
3. If NPort is used in a Dynamic IP environment, you can use NPort Administration suite, Web
Console, or Telnet Console to configure NPort to get an IP address dynamically with DHCP,
DHCP/BOOTP, or BOOTP.
ATTENTION
Consult your network administrator on how to reserve a fixed IP address (for your NPort) 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.
Factory Default IP Address
NPort products are configured with the following default private IP address:
Default IP address: 192.168.127.254
(IP addresses of the form 192.168.xxx.xxx are referred to as private IP addresses, sin c e it is not
possible to directly access a device configured with a private IP address from a public network.
For example, you would not be able to ping such a device from an outside Internet connection.
NPort applications that require sending data over a public network, such as the Internet, require
setting up the server with a valid public IP address, which can be leased from a local ISP.)
LCM Display
We recommend using the LCM display and four push buttons to configure the IP address for the
first time.
Basic Operation
If the NPort is working properly, the LCM panel will display a green color. The red Ready LED
will also light up, indicating that the NPort is receiving power. After the red Ready LED turns
green, you will see a display similar to:
N P 5 6 1 0 - 1 6 _ 3 8
1 9 2 . 1 6 8 . 1 2 7 . 2 5 4
Where
• NP5610-16 is the NPort’s name
• 38 is the NPort’s serial number
• 192.168.127.254 is the NPort’s IP address

selects the option listed on the LCM panel’s second line
The buttons are manipulated in a manner similar to the way a modern cellular phone operates. As
you move through the various functions and setting options, note that the top line shows the
current menu or submenu name, and the bottom line shows the submenu name or menu item that is
activated by pressing the SEL button.
Detailed Menu Options
The best way to explain all of NPort’s LCM functions is to refer to the table shown on the next
page. There are three main levels—1, 2, and 3—with each level represented by a separate column.
The first thing to remember is that the MENU button is used to move back and forth between the
LCM panel’s default screen, and main menu screen:
N P 5 6 1 0 - 1 6 _ 3 8
1 9 2 . 1 6 8 . 1 2 7 . 2 5 4
M a i n M e n U
S e r v e r s e t t i n g ↓
In addition, you only need to remember to:
• Use the SEL button to move up one level (i.e., left to right on the tree graph)
• Use the MENU button to move down one level (i.e., right to left on the tree graph)
• Use the cursor keys, U and V, to scroll between the various options within a level (i.e.,
up and down on the tree graph).
As you use the buttons to operate the LCM display, you will notice that with v ery few
exceptions, moving up one level causes the bottom line of the display to move to the top
line of the display. You will also notice that the botto m three options in level 2, and all of
the options in level 3 have either a C or D attached. The meaning is as fo llows:
• C = configurable (i.e., you are allowed to change the setting of this option)
•
D = display only (i.e., the setting for this option is displayed, but it cannot be changed)
This does NOT necessarily mean that the number does not change; only that you cannot
change it.

The part of the LCM operation that still requires some explanation is how to edit th e
configurable options. In fact, you will only encounter two types of configurable options.
The first type involves entering numbers, such as IP addresses, Netmasks, etc. In this case,
you change the number one digit at a time. The up cursor (U) is used to decrease the
highlighted digit, the down cursor (V) is used to increase the highlighted digit, and the sel
button is used to move to the next digit. When the last digit has been changed, pressing sel
simply enters the number into NPort 5600 Series’ memory.
The second type of configurable option is when there are only a small number of options
from which to choose (although only one option will be visible at a time). Consid er the

NPort Administration Suite
NPort Administration Suite consists of some useful utility programs that are used to configure and
manage your NPorts.
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.
ARP
You can make use of the ARP (Address Resolution Protocol) command to set up an IP address for
your NPort. The ARP command tells your computer to associate the NPort’s MAC address with
the intended IP address. You must then use Telnet to access the NPort, at which point the Device
Server’s IP address will be reconfigured.
ATTENTION
In order to use this setup method, both your computer and NPort must be connected to the same
LAN.
Or, you may use a cross-over Ethernet cable to connect the NPort directly to your computer’s
Ethernet card.
Your NPort must be configured with the factory default IP address—192.168.127.254—before
executing the ARP command, as described below.
3-5
NPort 5600 Series User’s Manual Choosing the Proper Operation Mode
Take the following steps to use ARP to configure the IP address:
1. Obtain a valid IP address for your NPort from your network administrator.
2. Obtain the NPort’s MAC address from the label on its bottom panel.
3. Execute the ‘arp -s’ command from your computer’s MS-DOS prompt by typing:
arp –s 192.168.200.100 00-90-E8-xx-xx-xx
This is where 192.168.200.100 is the new IP address and 00-90-E8-xx-xx- xx is the MAC address
for your NPort. You will need to change both numbers, as described above in points 1 and 2.
4. Next, execute a special Telnet command by typing:
telnet 192.168.200.100 6000
After issuing this command, a Connect failed message will appear, as shown here. After the
NPort reboots, its IP address should be updated to the new address, and you can reconnect
using Telnet, Web, or Administrator to check that the update was successful.
Telnet Console
Depending on how your computer and network are configured, you may find it convenient to use
network access to set up your NPort’s IP address. This can be done using the Telnet program.
ATTENTION
Figures in this section will use 5610-8 as an example.
1. From the Windows deskt op, c l i ck Start and then select Run.
2. Type telnet 192.168.127.254 (use the correct IP address if different from the default)
in the Open text input box, and then click OK.
3. When the Telnet window opens, if you are prompted to input the Console password, input the
password and then press Enter.
Note that this page will only appear if the NPort is password protected.

Chapter 4 Choosing the Proper Operation Mode
In this chapter, we describe the various NPort 5600 operation modes. The options include an
operation mode that uses a driver installed on the host computer, and operation modes that rely on
TCP/IP socket programming concepts. After choosing the proper operation mode in this chapter,
refer to Chapter 5 for detailed configuration parameter definitions.
The following topics are covered in this chapter:

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

NPort 5600 Series User’s Manual Web Console Configuration
The important point is that Real COM Mode allows users to continue using RS-232/422/485 serial
communications software that was written for pure serial communications applications. The driver
intercepts data sent to the host’s COM port, packs it into a TCP/IP packet, and then redirects it
through the host’s Ethernet card. At the other end of the connection, the NPort accepts the Ethernet
frame, unpacks the TCP/IP packet, and then transparently sends it to the appropriate serial device
attached to one of the NPort’s serial ports.
ATTENTION
Real COM Mode allows several hosts to have access control over the same NPort. The driver
that comes with your NPort controls host access to attached serial devices by checking the host’s
IP address.
Modify the Accessible IP Setting table when the legal IP address should be required in your
application
TCP Server Mode
In TCP Server mode, NPort provides a unique
IP:Port address on a TCP/IP network. NPort waits
passively to be contacted by the host computer,
allowing the host computer to establish a
connection with and get data from the serial device.
This operation mode also supports up to 4
simultaneous connections, so that multiple hosts
can collect data from the same serial device—at the
same time.
As illustrated in the figure, data transmission
proceeds as follows:
1. The host requests a connection from the NPort
configured for TCP Server Mode.
2. Once the connection is established, data can be
transmitted in both directions—from the host
to the NPort, and from the NPort to the host.

NPort 5600 Series User’s Manual Web Console Configuration
TCP Client Mode
In TCP Client mode, NPort can actively establish
a TCP connection to a pre-defined host computer
when serial data arrives.
After the data has been transferred, NPort can
automatically disconnect from the host computer
by using the TCP alive check time or Inactivity
time settings. Refer to chapter 5 for more details.
As illustrated in the figure, data transmission
proceeds as follows:
1. The NPort configured for TCP Client Mode
requests a connection from the host.
2. Once the connection is established, data can be
transmitted in both directions—from the host
to the NPort, and from the NPort to the host.
UDP Mode
Compared to TCP communication, UDP is faster
and more efficient. In UDP mode, you can
multicast data from the serial device to multiple
host computers, and the serial device can also
receive data from multiple host computers, making
this mode ideal for message display applications.

Pair Connection Mode
Pair Connection Mode employs two NPort 5600 in tandem, and can be used to remove the
15-meter distance limitation imposed by the RS-232 interface. One NPort 5600 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 5600.
The two NPort 5600 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) be tween the
two NPorts.

Router Server Server
Console management is commonly used by connecting to Console/AUX or COM ports of routers,
switches, and UPS units. Rtelnet works the same as RAW mode in that only one TCP port is
listened to after booting up. The system then waits for a host on the network to initiate a
connection. The difference is that the RAW mode does not provide the conversion function
provided by Telnet. If the connected devices need to use the CR/LF conversion function when
controlling, then users must choose Rtelnet mode.
Disabled Mode
Setting the operation mode of a particular port to Disabled, disables that port.
RFC2217 Mode
RFC2217 is a standard driver that provides Virtual COM function. RFC2217 defines general com
port control options based on telnet protocol. Any 3rd party dri ver supporti ng RFC 2217 c an be used
to implement virtual COM on NPort 5600 series. The driver establishes a transparent connection
between host and serial device by mapping the IP:Port of the NPort 5600 series’ serial port to a local
COM port on the host computer. (RFC2217 Mode supports 1 connection)

NPort 5600 Series User’s Manual Web Console Configuration
PPP Mode
NPort 5600 Device Server supports standard PPP service for out-of-band management if the Ethernet
network crashes. The PPP function enables dial-in access for users who need a remote access
solution. When a user at a remote site uses PPP dial-in to connect to NPort 5600, NPort 5600 plays
the role of a dial-in server. After the PPP connection is established, the user can remotely manage the
NPort 5600.

Network Settings
You must assign a valid IP address to NPort 5600 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 5600 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, and
BOOTP—located under the web console screen’s IP configuration drop-down box.

E.g., 255.255.255.0 255.255.255.0 Required
A subnet mask represents all the network hosts at one geographic location, in one building, or on
the same local area network. When a packet is sent out over the network, the NPort will use the
subnet mask to check if 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, a connection is established
directly from the NPort. Otherwise, the connection is established through the given default
gateway.

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

IP Address Report
When NPort 5600 series products are used in a dynamic IP environment, users must spend more
time with IP management tasks. For example, if NPort 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, the host must have some way of determining NPort’s new IP address.
NPort 5000 series products help out by periodically reporting their IP address to the IP location
server, in case the dynamic IP has changed. The parameters shown below are used to configure the
Auto IP report function. There are two ways to develop an “Auto IP report Server” to receive
NPort’s Auto IP report.
1. Use NPort Administrator’s IP Address Report function.
2. “Auto IP report protocol,” which can automatically receive the Auto IP report on a regular
basis, is also available to help you develop your own software. Refer to Appendix E for the
“Auto IP report protocol”.

NPort 5600 Series User’s Manual Configuring NPort Administrator
Max connection
Setting Factory Default Necessity
1, 2, 3, 4 1 Required
Max connection is usually used when the user needs to receive data from different hosts
simultaneously. The factory default is 1. In this case, only one specific host can access this port of
the NPort, and the Real COM driver on that host will have full control over the port.
Max. connection 1:
Allows only a single host’s Real COM driver to open the specific NPort serial port.
Max connection 2 to 4:
Allows 2 to 4 hosts’ Real COM drivers to open the specific NPort serial port at the same time.
When multiple hosts’ Real COM drivers open the serial port at the same time, the COM driver
only provides a pure data tunnel without control ability. That is, this serial port parameter will use
firmware’s settings, not depend on your appl i cat i on pr o gram (AP) .
Application software that is based on the COM driver will receive a driver response of “success”
when the software uses any of the Win32 API functions. The firmware will only send the data
back to the driver on the host.
Data will be sent first-in-first-out when data comes into the NPort from the Ethernet interface.
Ignore jammed IP
Setting Factory Default Necessity
No or Yes No Required
For previous versions of NPort 5200, when Max connections > 1, and the serial device is
transmitting data, if any one of the connected hosts was not responding NPort 5200 would wait
until the data had been transmitted successfully before transmitting the second group of data to all
hosts. For the current version of NPort 5200, 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 Required
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 5200 may get configuration changes from multiple hosts, the most
recent command received will take precedence.
ATTENTION
When Max connection is set to 2, 3, or 4, this means that NPort will be using a “multi connection
application” (i.e., 2, 3, or 4 hosts are allowed access to the port at the same time). When using a
multi connection application, NPort will use the serial communication parameters set in the
console. All of the hosts connected to that port must use the same serial settings. If one of the
hosts opens the COM port with parameters that are different from NPort’s console setting, data
communication may not work properly.

Packing length
Setting Factory Default Necessity
0 to 1024 0 Required
Default = 0, The Delimiter Process will be followed, regardless of the length of the data packet. If
the data length (in bytes) matches the configured value, the data will be forced out. The data length
can be configured for 0 to 1024 bytes. Set to 0 if you do not need to limit the length.
Delimiter 1
Setting Factory Default Necessity
00 to FF None Optional
Delimiter 2
Setting Factory Default Necessity
00 to FF None Optional
Once the NPort receives both delimiters through its serial port, it immediately packs all data
currently in its buffer and sends it to the NPort’s Ethernet port.
ATTENTION
Delimiter 2 is optional. If left blank, then Delimiter 1 alone trips clearing of the buffer. If the size
of the serial data received is greater than 1 KB, the NPort will automatically pack the data and
send it to the Ethernet. However, to use the delimiter function, you must at least enable Delimiter
1. If Delimiter 1 is left blank and Delimiter 2 is enabled, the delimiter function will not work
properly.
Delimiter process
Setting Factory Default Necessity
Do nothing, Delimiter + 1, Delimiter +
2, Strip Delimiter
When [Delimiter + 1] or [Delimiter + 2] is selected, the data will be transmitted when an
additional byte (for Delimiter +1), or an additional 2 bytes (for Delimiter +2) of data is received
after receiving the Delimiter.
When [Strip Delimiter] is selected, when the Delimiter is received, the Delimiter is deleted (i.e.,
stripped), and the remaining data is transmitted.
When [Do nothing] is selected, the data will be transmitted when the Delimiter is received.
Force transmit
Setting Factory Default Necessity
0 to 65535 ms 0 ms Optional
Do Nothing Required
0: Disable the force transmit timeout.
1 to 65535: Forces the NPort’s TCP/IP protocol software to try to pack serial data received during
the specified time into the same data frame.
5-13
NPort 5600 Series User’s Manual Configuring NPort Administrator
This parameter defines the time interval during which NPort fetches the serial data from its
internal buffer. If data is incoming through the serial port, NPort stores the data in the internal
buffer. NPort transmits data stored in the buffer via TCP/IP, but only if the internal buffer is full or
if the Force transmit time interval reaches the time specified under Force transmit timeout.
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 none for 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 the series of characters in the same packet, the serial device attached to
NPort should send that series of characters during a time interval less than the Force Transmit
timeout for NPort, and the total length of data must be less than or equal to NPort’s internal buffer
size. The serial communication buffer size for NPort is 1 KB per port.
TCP Server Mode
TCP alive check time
Setting Factory Default Necessity
0 to 99 min 7 min Optional
0 min: TCP connection is not closed due to an idle TCP connection.
1 to 99 min: NPort automatically closes the TCP connection if there is no TCP activity for the
given time. After the connection is closed, NPort starts listening for another host’s TCP
connection.

NPort 5600 Series User’s Manual Configuring NPort Administrator
Inactivity time
Setting Factory Default Necessity
0 to 65535 ms 0 ms Optional
0 ms: TCP connection is not closed due to an idle serial line.
0-65535 ms: NPort automatically closes the TCP connection if there is no serial data activity for
the given time. After the connection is closed, NPort starts listening for another host’s TCP
connection.
This parameter defines the maintenances status as Closed or Listen on the TCP connection. The
connection is closed if there is no incoming or outgoing data through the serial port during the
specific Inactivity time.
If the 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 will check the connection
status between the NPort and remote host by sending “keep alive” packets periodically. If the
remote host does not respond to the packet, NPort assumes that the connection was closed down
unintentionally. NPort will then force the existing TCP connection to close.
ATTENTION
The Inactivity time should at least be set larger than that of Force transmit timeout. To prevent
the unintended loss of data due to the session being disconnected, it is highly recommended that
this value is set large enough so that the intended data transfer is completed.
Max connection
Setting Factory Default Necessity
1, 2, 3, 4 1 Required
Max connection is usually used when the user needs to receive data from different hosts
simultaneously. The factory default only allows 1 connection at a time.
Max. connection 1:
NPort only allows 1 host to open the TCP connection to the specific serial port.
Max connection 2 to 4:
Allows 2 to 4 host’s TCP connection request to open this NPort serial port, at the same time. When
multiple hosts establish a TCP connection to the specific serial port at the same time, NPort will
duplicate the serial data and transmit to all of the hosts. Ethernet data is sent on a first-in-first-out
basis to the serial port when data comes into NPort from the Ethernet interface.
Ignore jammed IP
Setting Factory Default Necessity
No or Yes No Required
For previous versions of NPort 5200, when Max connections > 1, and the serial device is

Pair Connection Mode
Pair Connection Mode employs two NPort 5600 device servers in tandem, and can be used to
remove the 15-meter distance limitation imposed by the RS-232 interface. One NPort 5600 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 5600. The two NPort 5600 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 (althoug h it cannot transmit the
DCD signal) between the two NPorts.
Pair Connection Master Mode
When using Pair Connection Mode, you must select Pair Connection Master Mode for the

Packing length
Setting Factory Default Necessity
0 to 1024 0 Optional
Default = 0, The Delimiter Process will be followed, regardless of the length of the data packet. If
the data length (in bytes) matches the configured value, the data will be forced out. The data length
can be configured for 0 to 1024 bytes. Set to 0 if you do not need to limit the length.

00 to FF (hex) None Optional
Once the NPort 5600 receives both delimiters through its serial port, it immediately packs all data
currently in its buffer and sends it to the NPort 5600’s Ethernet port.
ATTENTION
Delimiter 2 is optional. If left blank, then Delimiter 1 alone trips clearing of the buffer. If the size
of the serial data received is greater than 1 KB, the NPort 5600 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.

Do Nothing Optional
5-29
NPort 5600 Series User’s Manual Configuring NPort Administrator
This parameter defines the time interval during which NPort 5600 fetches the serial data from its
internal buffer. If data is incoming through the serial port, NPort 5600 stores the data in the
internal buffer. NPort 5600 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 5600 should send that series of characters during a time interval less than the Force transmit
timeout for NPort 5600, and the total length of data must be less than or equal to NPort 5600’s
internal buffer size. The serial communication buffer size for NPort 56 0 0 is 1 KB per port .

COM Mapping
NPort Administration Suite comes with Windows 95/98/ME/NT/2000/XP Real COM drivers.
After you install Windows Administration Suite, there are two ways to set up the NPort’s 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 the NPort 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 connecting the NPort to the network
first. Off-line COM Mapping can decrease the system integrator’s effort by solving different field
problems. Via off-line installation, the user can process the host software installation and then
install the NPort to different fields.
Use the following procedure to map COM ports:
1. On-line COM Mapping:
Connect NPort to the network Æ Set NPort 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 to the network Æ Configure
NPort’s IP address.
6-20
NPort 5600 Series User’s Manual IP Serial LIB
On-line COM Mapping
1. Broadcast Search for NPorts 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 list that appears is the list generated by the previous Broadcast Search. Select the
NPort to which you would like to map COM ports.
6-21
NPort 5600 Series User’s Manual IP Serial LIB
5. Select COM Setting 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 NPorts, remember to check the “Auto
Enumerating” function to use the COM No. you select as the first COM No.
Hi-performance mode is the default for Tx mode. If the driver completes sending data out to
the NPort, 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; 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 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 fo r 2G NP o rt a dds it afte r version 1.2.
For some applications, the user’s program will use the Win32 “PurgeComm()” function
before it reads or writes data. With our design, after the program uses this Purge Comm()
function, the NPort driver will keep querying NPort’s firmware several times to make sure
there is really no data queued in the NPort firmware buffer, rather than just flushing the local
buffer. This kind of design is used because of some special considerations. However, it might
take more time (on the order of several hundred milliseconds) than a native COM1, because it
needs to work via Ethernet. That’s why the native COM ports on the motherboard can work
fast with this function call, but NPort requires much more time. In order to accommodate
other applications that require a faster response time, the new NPort driver implements a new
“Fast Flush” option. Note that by default, this function is disabled.
To begin with, make sure there are some “PurgeComm()” functions being used in your
application program. In this kind of situation, you might find that your NPort exhibits a much
poorer operation performance than when using the native COM1 port. Once you have enabled
the “Fast Flush” function, you can check to see if there has been an improvement in
performance.
By default, the optional “Fast Flush” function is disabled. If you would like to enable this
function, from the “NPort Administrator,” double click 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().”
The Serial Parameter settings shown here are the default settings when the NPort is powered
on. However, the program can redefine the serial parameters to different values after the
program opens the port via Win 32 API.

7. 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.
8. Select Discard Change to tell Administrator NOT to save the COM Mapping information to
the host.
9. To save the configuration to a text file, select Export COM Mapping. You will then be able
to import this configuration file to another host and use the same COM Mapping settings in
the other host.

IP Location
When NPort 5600 series products are used in a dynamic IP environment, users must spend more
time with IP management tasks. NPort 5600 series products help out by periodically reporting
their IP address to the IP location server, in case the dynamic IP has changed.
y Receive NPort’s IP location report
y Centralize NPort’s IP management in a dynamic IP environment.
1. Configure NPort with Dynamic IP settings. For example, DHCP, BOOTP and DHCP/BOOTP.
Assign the remote Auto IP report server’s IP address and UDP port.
2. Select the IP Location Report, and click the right mouse button to select Settings.
3. Then configure the Local Listen Port to be the same as the NPort’s “Auto report to UDP port”
setting.
4. Click GO to start receiving the Auto IP address report from the NPort.

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