NPort S8000 Series Introduction

1-2

Overview

The NPort S8000 is an industrial device server that integrates a managed Ethernet switch with a fully functional

serial device server. The NPort S8000 device servers are designed to make your industrial serial devices

instantly Internet-ready.

The NPort S8458 offers four fiber Ethernet ports, four Ethernet ports, and four RS-232/422/485 serial ports in

a single device. Its design not only saves cabinet space and reduces power consumption, but also saves money

since you don’t need to purchase separate switches and serial device servers.

The compact size of the NPort S8000 device servers makes them the ideal choice for connecting

RS-232/422/485 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 LAN or the Internet.

The NPort S8000 is a fully equipped managed Ethernet Switch with a suite of useful maintenance and

monitoring functions, and it is designed to provide smooth and reliable operation in harsh industrial

environments. It is ideal for keeping automation systems running continuously, sending status reports to help

prevent system damage and losses, and managing your industrial Ethernet networks and serial devices.

Industrial Communications and Automation

As the world’s networking and information technology becomes more complex, Ethernet has become the major

communications interface in many industrial communications and automation applications. In fact, a whole

new industry has sprung up to provide Ethernet products that comply with the requirements of demanding

industrial applications.

Industrial vs. Commercial

Users have found that when transplanting Ethernet from comfortable office environments to harsh and less

predictable industrial environments, commercial Ethernet equipment available in today’s market simply cannot

meet the high-reliability requirements demanded by industrial applications. This means that more robust

networking equipment, commonly referred to as industrial Ethernet equipment, is required for these

applications.

Informative vs. Passive

Since industrial Ethernet devices are often located at the endpoints of a system, such devices cannot always

know what’s happening elsewhere on the network. This means that industrial Ethernet communication

equipment that connects these devices must provide system administrators with real-time alarm messages.

Wiring Requirements

You should heed the following:

• 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 the Power

Connect the 12-48 VDC power line with the NPort S8000’s terminal block. 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.

Take the following steps to wire the redundant power inputs:

1. Insert the negative/positive DC wires into the V-/V+ terminals.

2. To keep the DC wires from pulling loose, use a small flat-blade screwdriver to tighten the wire-clamp screws

on the front of the terminal block connector.

3. Insert the plastic terminal block connector prongs into the terminal block receptor, which is located on the

EDS’s top panel.

Adjustable Pull High/low Resistors and Terminators for the

RS-485 Port (NPort S8455I Series only)

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 there is no resistor value that works for every environment, DIP

switches are used to set the pull high/low resistor values for each RS-485 port.

To set the pull high/low resistors to 150 KΩ, make sure both of the assigned DIP switches are in the OFF

position. This is the default setting.

To set the pull high/low resistors to 1 KΩ, make sure both of the assigned DIP switches are in the ON

position.

ATTENTION

Consult your network administrator on how to reserve a

IP

mapping table when using a DHCP server or BOOTP server. For most applications, you should assign a fixed IP

address to your NPort S8000.

Static and Dynamic IP Addresses

Determine whether your NPort S8000 needs to use a static IP or dynamic IP address (either DHCP or BOOTP

application).

• If your NPort S8000 is used in a static IP environment, you will assign a specific IP address using one

of the tools described in this chapter.

• If your NPort S8000 is used in a dynamic IP environment, the IP address will be assigned

automatically over the network. In this case, set the IP configuration mode to DHCP, BOOTP.

fixed IP address for your NPort S8000 in the MAC-

Factory Default IP Address

The NPort S8000 is configured with the following default private IP address:

192.168.127.254

Note that IP addresses that begin with “192.168” are referred to as private IP addresses. Devices configured

with a private IP address are not directly accessible from a public network. For example, you would not be able

to ping a device with a private IP address from an outside Internet connection. If your application requires

sending data over a public network, such as the Internet, your NPort S8000 will need a valid public IP address,

which can be leased from a local ISP.

Configuration Options

Device Search Utility

Web Console

ARP

You may configure your NPort S8000 with the bundled Device Search Utility (DSU) for Windows platform. Note

that you will be asked to enter the username and password to access the NPort S8000 device. The default

username is admin and the default password is moxa. Please refer to Chapter 5, “Use Real COM Mode to

Communicate with Serial Devices”, for details on how to install and use the DSU.

You may configure your NPort S8000 using a standard web browser. Note that you will be asked to enter the

username and password to access the NPort S8000 device. The default username is admin and the default

password is moxa. Please refer to Chapter 6, “Basic Settings and Device Server Configuration”, for details on

how to access and use the NPort S8000 web console.

You may use the Address Resolution Protocol (ARP) command to set up an IP address for your NPort S8000.

The ARP command tells your computer to associate the NPort S8000’s MAC address with an IP address.

Afterwards, use Telnet to access the NPort S8000 and its IP address will be reconfigured.

NPort S8000 Series Initial IP Address Configuration

3-3

ATTENTION

In order to use the ARP setup method, both your computer and

same LAN. Alternatively, you may use a crossover Ethernet cable to connect the NPort S8000 directly to your

computer’s Ethernet card. Before executing the ARP command, your NPort S8000 must be configured with the

factory default IP address (192.168.127.254), and your computer and the NPort S8000 must be on the same

subnet.

To use ARP to configure the IP address, complete the following:

1. Obtain a valid IP address for your NPort S8000 from your network administrator.

2. Obtain your NPort S8000’s MAC address from the label on the bottom panel.

3. Execute the arp -s command from your computer’s MS-DOS prompt (for Windows 7 or newer OS, please

ensure you have the administrator authority to execute the MS-DOS prompt) as follows:

The

Serial Console

The NPort S8000 supports configuration through the serial console, which is the same as the Telnet console but

accessed through the RS-232 console port rather than through the network. Once you have entered the serial

console, the configuration options and instructions are the same as if you were using the Telnet console.

The following instructions and screenshots show how to enter the serial console using PComm Terminal

Emulator, which is available free of charge as part of the PComm Lite suite. You may use a different terminal

emulator utility, although your actual screens and procedures may vary slightly from the following instructions.

1. Use a serial cable to connect the NPort S8000’s serial console port to your computer’s male RS-232 serial

port.

NPort S8000 has a dedicated serial console port.

2. From the Windows desktop select Start  All Programs  PComm Lite  Terminal Emulator.

3. The PComm Terminal Emulator window should appear. From the Port Manager menu, select Open, or

simply click the Open icon as shown below:

4. The Property window opens automatically. Select the Communication Parameter tab, then select the

appropriate COM port for the connection (COM1 in this example). Configure the parameters for 19200, 8,

N, 1 (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 click OK.

The NPort S8000 will then automatically switch from data mode to console mode.

6. After you enter the password, or if password protection was not enabled, you will be prompted to select the

terminal mode. Press 1 for ansi/vt100 and then press ENTER.

7. Enter the username and password to login to the console. The default username and password are admin

and moxa, respectively. The main menu should come up. Once you are in the console, you may configure

the IP address through the Network menu item, just as with the Telnet console. Please refer to steps 4 to

8 in the Telnet Console section to complete the initial IP configuration.

4. Choosing the Serial Operation Mode

In this chapter, we describe the various serial operation modes of the NPort S8000. 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 6 for

detailed configuration parameter definitions.

Overview

The device server function of the NPort S8000 enables network operation of 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 the NPort S8000 networks 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 S8000 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 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 a speedier delivery. UDP also allows multicasting of data to groups of IP addresses.

Real COM Mode

NPort S8000 comes equipped with COM drivers that

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.

Mode allows several hosts to have access control over the same NPort. The driver that comes

RFC2217 Mode

RFC-2217 mode is similar to Real COM mode. That is, 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 S8000 to a local COM port

on the host computer. RFC2217 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 S8000 serial port(s).

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.
