Chapter 1 Introduction

Welcome to the MOXA NPort 5600 Series of advanced serial device servers that make it easy to
network-enable your serial devices. The NPort 5600 Series has 8 models: NPort 5610-16, NPort
5610-8 (16/8 ports for RS-232, with AC power), NPort 5610-16-48V, NPort 5610-8-48V (16/8
ports for RS-232, with DC power), NPort 5630-16, NPort 5630-8 (16/8 ports for RS-422/485,
with AC power), NPort 5630-16-48V, NPort 5630-8-48V (16/8 ports for RS-422/485, with DC
power). In this manual, we often refer to the four products collectively as “5600” or “5600
Series.”

The following topics are covered in this chapter:

Overview

NPort 5600 Series serial device servers are designed to make your industrial serial devices
Internet ready instantly. The compact size of NPort 5600 device servers makes them the ideal
choice for connecting your RS-232 (NPort 5610-16/8) or RS-422/485 (NPort 5630-16/8) 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.

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.

NPort 5600 serial device servers support automatic IP configuration protocols (DHCP, BOOTP)
and manual configuration via NPort’s handy web browser console. Both methods ensure quick
and effective installation. And with NPort 5600’s Windows Utility, installation is very
straightforward, since all system parameters can be stored and then copied to other device servers
simultaneously.

Connecting the Hardware

This section describes how to connect NPort 5600 Series to serial devices for first time testing
purposes. We cover Wiring Requirements, Connecting NPort 5610/30-16/8’s Power,

Connecting NPort 5610/30-16/8-48V’s Power, Grounding NPort 561/30-16/8-48V,
Connecting to the Network, Connecting to a Serial Device, and LED Indicators.

Wiring Requirements

Be sure to disconnect the power cord before installing and/or wiring your NPort 5600.

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.

Getting Started

Safety First!

Wiring Caution!

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:

 Use separate paths to route wiring for power and devices. If power wiring and device wiring

paths must cross, make sure the wires are perpendicular at the intersection point.

NOTE: Do not run signal or communication wiring and power wiring in the same wire
conduit. To avoid interference, wires with different signal characteristics should be routed
separately.

 You can use the type of signal transmitted through a wire to determine which wires should be

kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can
be bundled together.

 Keep input wiring and output wiring separate.

 Where necessary, it is strongly advised that you label wiring to all devices in the system.

Connecting NPort 5610/30-16/8’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.

NPort 5600 Series User’s Manual

Connecting NPort 5610/30-8/16-48V’s Power

To connect NPort 5610/30-8/16-48V’s power cord with its terminal block, follow the steps given
below:

and V- terminals of NPort 5610/30-8/16-48V’s terminal

+

NOTE

1. Loosen the screws on the V
block.

2. Connect the power cord’s 48 VDC wire to the terminal block’s V

power cord’s DC Power Ground wire to the terminal block’s V- terminal, and then
tighten the terminal block screws. (Note: NPort 5610/30-8/16-48V can still operate
even if the DC 48V and DC Power Ground are reversed.)

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.

You should use 8 kg-cm of screw torque and 22-14 AWG of suitable electric wire to connect NPort
5610/30-8/16-48V’s power cord to its terminal block.

Grounding NPort 5610/30-16/8-48V

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.

The Shielded Ground (sometimes called Protected Ground) contact is

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.

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:

 Initializing NPort’s IP Address

 Factory Default IP Address

 LCM Display  recommended configuration method

 NPort Administration Suite  recommended configuration method

 ARP

 Telnet Console

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, ARP,
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.

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, since it is not
possible to directly access a device configured with a private IP address from a public network.
For example, you would not be able to ping such a device from an outside Internet connection.
NPort 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

This is 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

NPort 5600 Series User’s Manual

Initial IP Address Configuration

There are four push buttons on NPort’s nameplate. Going from left to right, the buttons are:

Button Name

MENU menu activates the main menu, or returns to an upper level

U

V

SEL

up cursor

down cursor

select

Action

scrolls up through a list of items shown on the LCM panel’s second line
scrolls down through a list of items shown on the LCM panel’s second

line
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).

NPort 5600 Series User’s Manual

3-3

As you use the buttons to operate the LCM display, you will notice that with very 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 bottom three options in level 2, and all of
the options in level 3 have either a C or D attached.
The meaning is as follows:

• 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 doesn’t change; only that you can’t change
it)

NPort 5600 Series User’s Manual

Initial IP Address Configuration

The part of the LCM operation that still requires some explanation is how to edit the
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). Consider the
Parity attribute under Serial set as an example. Follow the tree graph to arrive at the
following Parity screen. The first option, None, is displayed, with a down arrow all the
way to the right. This is an indication that there are other options from which to choose.

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.

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.

NPort 5600 Series User’s Manual

3-5

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:

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 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’s IP address. This can be done using the Telnet program.

arp –s 192.168.200.100 00-90-E8-xx-xx-xx

Figures in this section will use 5610-8 as an example.

1. From the Windows desktop, click on Start and then select Run.

2. Type telnet 192.168.127.254 (use the

correct IP address if different from the default) in
the Open text input box, and then click OK.

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.

4. Type 2 to select Network settings, and then press

Enter.

Chapter 4 Choosing the Proper Operation Mode

In this section, we describe the various NPort 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 operating mode in this chapter, refer to
Chapter 5 for detailed configuration parameter definitions.

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 ports (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.

In addition to providing socket access, 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.

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.

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

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 to connect to 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

Choosing the Proper Operation 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 multiple host
computers, making this mode ideal for message
display applications.

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.

The driver used for Real COM Mode comes with the NPort Windows Administrator which will
install automatically on your computer when you install NPort Administration Suite.

NPort 5600 Series User’s Manual

4-3

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.

Real COM Mode allows several hosts to have access control of the same NPort. The Moxa driver that
comes with your NPort controls host access to attached serial devices by checking the host’s IP
address.

Refer to Accessible IP Settings in Chapter 5 for more details.
