Connecting the Hardware
This section describes how to connect the NPort 5100 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
Connect the 12 to 48 VDC power code with NPort 5100’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.
NPort 5100 Series User’s Manual Getting Started
2-3
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.
LED Name LED Color LED Function

Tx/Rx
Off No data is being transmitted or received through the serial port.
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.
NPort 5100 Series User’s Manual Getting Started
2-4
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.

Chapter 3 Initial IP Address Configuration
When setting up your NPort 5100 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 5100’s IP Address
Factory Default IP Address

ARP
Telnet Console
Serial Console (19200, n, 8, 1)
NPort 5100 Series User’s Manual Initial IP Address Configuration
3-2
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.
NPort 5100 Series User’s Manual Initial IP Address Configuration
3-3
Take the following steps to use ARP to configure the IP address:
1. Obtain a valid IP address for your NPort 5100 from your network administrator.
2. Obtain the NPort 5100’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 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.

Serial Console (19200, n, 8, 1)
You may use the RS-232/422/485 console port to set up the IP address for NPort 5100. 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 5100 via serial console, turn off the power and connect the
serial cable from NPort 5100 to your computer’s serial port.
1. Connect NPort 5100’s serial port 1 directly to your computer’s male RS-232/422/485 serial
port.
2. From the Windows desktop, click Start Æ Programs Æ PComm Lite Æ Terminal
Emulator.
3. When the PComm Terminal Emulator window opens, first click on the Port Manager
menu item and select Open, or simply click on the Open icon.
4. The Property window opens automatically. From the Communication Parameter page,
select the appropriate COM port for the connection, COM1 in this example, and 19200 for
Baud Rate, 8 for Data Bits, None for Parity, and 1 for Stop Bits.
5. From the Property window’s Terminal page, select ANSI or VT100 for Terminal Type and
then click OK.
If you select Dumb Terminal as the terminal type, some of the console functions—especially
the “Monitor” function—may not work properly.
6. Press the “ ` ” key continuously and then power on the NPort 5100.

Chapter 4 Choosing the Proper Operation Mode
In this section, we describe the various NPort 5100 operation modes. The options include Real
COM Mode, which 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 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
4-3
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.

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. The NPort 5100 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 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.

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.

Opening Your Browser
1. Open your browser with the cookie function enabled. (To enable your browser for cookies,
right click on your desktop Internet Explorer icon, select Properties, click on the Security tab,
and then select the three Enable options as shown in the figure below.)
2. Type
192.168.127.254 in the Address input box (use the correct IP address if different from
the default), and then press Enter.
3. Input the password if prompted. The password will be transmitted with MD5 encryption over
the Ethernet. Note that you will not be prompted to enter the password if the NPort 5100 is not
currently password protected.
ATTENTION
If you use other web browsers, remember to Enable the functions to “allow cookies that are
stored on your computer” or “allow per-session cookies.”
NPort 5100 uses cookies only for “password” transmission.
ATTENTION
Refer to Chapter 3, Initial IP Address Configuration, to see how to configure the IP address.
Examples shown in this chapter use the Factory Default IP address (192.168.127.254).

4. The NPort 5100 homepage will open next. On this page, you can see a brief description of the
Web Console’s nine function groups.
ATTENTION
If you can’t remember the password, the ONLY way to start configuring the NPort 5100 is to
load factory defaults by using the Reset button located near the NPort 5100’s RJ45 Ethernet port.
Remember to use NPort Administrator to export the configuration file when you have finished
the configuration. After using the Reset button to load factory defaults, your configuration can be
easily reloaded into the NPort 5100 by using the NPort Administrator Import function. Refer to
Chapter 6 for more details about using the Export and Import functions.
ATTENTION
If your NPort 5100 application requires using password protection, you must enable the cookie
function in your browser. If the cookie function is disabled, you will not be allowed to enter the
Web Console Screen.

Network Settings
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,
and BOOTP—located under the web console screen’s IP configuration drop-down box.
