1. Introduction

The NPort 6000 series of secure serial device servers has many exceptional features. More than 20 models

comprise the NPort 6000 series of secure serial device servers. The main differences between the models are

the number of ports and the type of network connection employed. All instructions and information presented

for the NPort 6000 apply to all models in the series. Any differences between models will be specified. Please

refer to the Product Selection Chart section in this chapter for details on differences between models in the

series.

The following topics are covered in this chapter:

NPort 6000 Series Introduction

1-2

NPort 6650-32

Overview

The NPort 6000 can be used to connect any serial device to an Ethernet network and supports many different

operation modes. In particular, the NPort 6000 also supports Secure TCP Server, Secure TCP Client, Secure

Pair-Connection, and Secure Real COM modes for security-critical applications, such as banking, telecom,

access control, and remote site management. Moreover, for firmware v1.14 and above, the NPort 6000 series

enhances its security level to comply with industry standard IEC 62443-4-2 at level 2 in the following focused

areas: more secure protocols supported, authentication control, more complex data encryptions, and so on.

The NPort 6000’s Any Baudrate feature, which is based on Moxa’s UART IC, allows the use of nonstandard

baudrates. For example, a baudrate of 500 kbps may be required for some special applications. Many device

servers could only be configured for a baudrate of 460.8 kbps, resulting in an error rate of 7.84%. For serial

communication, the acceptable margin of error is only 3%. The NPort 6000 allows you to configure the

baudrate more accurately, and it can be configured to transmit serial data at the rate of 491.5 kbps. This is only

a 1.7% margin of error, which is well within the acceptable margin for serial data.

For some applications, data must be delivered reliably even if communication is disrupted. The NPort 6000

provides a powerful function to ensure that data is buffered in case of a communication failure. When a

communication failure occurs, the data is stored in the NPort 6000. Upon resumption of communication, the

buffered data will be sent to the destination. The default size of the port buffer is 64 KB for each port. For the

NPort 6610, NPort 6250, NPort 6450, and NPort 6650, users may increase the buffer size by using an external

SD card.

Package Checklist

Each NPort 6000 serial device server is shipped in a separate box, which also includes a number of standard

accessories. In addition, several optional accessories can be ordered separately. When you receive your

shipment, please check the contents of the box carefully and notify your Moxa sales representative if any of the

items are missing or appear to be damaged.

The NPort 6150, 6250, and 6450 device servers have

in “ears” for attaching the device

server to a wall or the inside of a cabinet. We suggest using two screws per ear to attach the

device servers to a wall or the inside of a cabinet. The heads of the screws should be less than

6.0 mm in diameter, and the shafts should be less than 3.5 mm in diameter, as shown in the

figure at the right.

You should also heed the following guidelines:

• 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.

• The type of signal transmitted through a wire should determine which wires should be kept separate. The

rule of thumb is that wires sharing similar electrical characteristics may be bundled together.

• Keep input wiring and output wiring separate.

• It is good practice to label the wiring to all devices in the system.

Connecting to the Network

Connect one end of the Ethernet cable to the NPort 6000’s 10/100M Ethernet port and the other end of the

cable to the Ethernet network. If you are using a fiber-port version of the NPort 6000, connect the fiber cable

from the Ethernet network to the NPort 6000’s fiber port.

If the cable is properly connected, the NPort 6000 will indicate a valid connection to the Ethernet as follows:

• The Ethernet LED glows solid green when connected to a 100 Mbps Ethernet network.

• The Ethernet LED glows solid orange when connected to a 10 Mbps Ethernet network.

• The Ethernet LED flashes when Ethernet packets are being transmitted or received.

Connecting to a Serial Device

Connect the serial data cable between the NPort 6000 and the serial device. Serial data cables are available as

optional accessories.

LED Indicators

The LED indicators on the front panel of the NPort 6000 are described in the following table.

Adjustable Pull High/Low Resistors 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 termination resistors, it is important to set the pull high/low resistors correctly so that the

electrical signal is not corrupted. The NPort 6000 uses jumper settings or DIP switches to set the pull high/low

resistor values for each serial port.

3. Initial IP Address Configuration

When setting up the NPort 6000 for the first time, the first thing you should do is configure its IP address. This

chapter introduces the different methods that can be used.

The following topics are covered in this chapter:

Static and Dynamic IP Addresses

Factory Default IP Address

NPort 6000 Series Initial IP Address Configuration

3-2

ATTENTION

Consult your network administrator on how to reserve a fixed IP address for your NPort 6000 in the MAC-IP

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

IP address to your NPort 6000.

Static and Dynamic IP Addresses

Determine whether your NPort 6000 needs to use a static IP or dynamic IP address (either DHCP or

BOOTP/PPPoE application).

• If your NPort 6000 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 6000 is used in a dynamic IP environment, the IP address will be assigned

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

BOOTP, or PPPoE.

Factory Default IP Address

The NPort 6000 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 6000 will need a valid public IP address,

which can be leased from a local ISP.

Configuration Options

Device Search Utility

You may configure your NPort 6000 with the bundled Device Search Utility for Windows. Note that you will be

asked to enter the user

name and password to access the NPort 6000 device. The default username is admin and the default password

is moxa. Please refer to Chapter 13, Software Installation/Configuration, for details on how to install and use

the Device Search Utility.

Web Console

You may configure your NPort 6000 using a standard web browser. Note that you will be asked to enter the

username and password to access the NPort 6000 device. The default username is admin and the default

password is moxa. Please refer to Chapter 5, Configuration with the Web Console, for details on how to access

and use the NPort 6000 web console.

LCM Console/Front Panel (NPort 6610, 6650, and 6450 only)

The NPort 6610, 6650, and 6450 only give you the option to configure some settings through the front panel,

also known as the LCM (Liquid Crystal Module) console. The LCM console can be configured for read-only or

writeable access. Read-only access allows settings to be viewed but not changed. Factory default settings are

4. Introducing Serial Port Operation Modes

In this chapter, we describe the various operation modes of the NPort 6000. NPort 6000 modes are grouped by

type of application, such as Device Control or Reverse Terminal. The options include an operation mode that

relies on a driver installed on the host computer and operation modes that rely on TCP/IP socket programming

concepts. After selecting the proper operation mode, refer to Chapter 5, Configuration with the Web

Console, for detailed information on configuration parameters.

Overview

The NPort 6000 network enables traditional serial (RS-232/422/485) devices. The serial device server is a tiny

computer equipped with a CPU 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 to collect data from various kinds of

instruments. Since the NPort 6000 network-enables instruments equipped with an RS-232, RS-422, or RS-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 6000 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 will not be

limited by the host computer’s bus limitation (such as ISA or PCI), nor will you be limited by the absence of

drivers for various operating systems.

In addition to providing socket access, the NPort 6000 also comes with a Real COM/TTY driver that transmits

all serial signals intact. This enables you to preserve your existing COM/TTY-based software 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 faster delivery. UDP also allows unicast or multi-unicast of data to one IP or groups of IP addresses.

The NPort 6000 also supports console management applications, including Reverse Telnet, as well as Reverse

SSH terminal modes. Reverse terminal modes enable you to connect to a server’s console port through an IP

network for remote control and/or monitoring of that server.

The NPort 6000 supports standard SSL secure data access for Real COM/TTY mode, TCP server mode, TCP

Client mode, and Pair Connection mode. Data transmitted on the Ethernet will be well protected.

Guide to NPort 6000 Modes

On the NPort 6000, each serial port is independently configurable for a different mode with different settings.

For example, on the NPort 6450, an administrator can easily configure two ports for Real COM mode, one port

for Ethernet Modem mode, and one port for Reverse Telnet mode. Please refer to Chapter 7, Configuring Serial

Port Operation Modes, for detailed information and configuration instructions.

NPort 6000 Series Introducing Serial Port Operation Modes

4-3

ATTENTION

Real COM mode allows several hosts to have access control over the same NPort 6000. The drivers that come

with your NPort 6000 control host access by checking the host’s IP address. Please refer to the Accessible IP

List

Device-Control Applications

For device-control applications, the NPort 6000 offers the following modes: Real COM/Secure Real COM mode

and RFC2217 mode.

Real COM and Secure Real COM Modes

The NPort 6000 comes bundled with Real COM drivers for Windows systems and TTY drivers for Linux systems.

Real COM mode includes optional data encryption, using SSL.

In Real COM mode, the bundled drivers are able to establish a transparent connection between a host and a

serial device by mapping the serial port on the NPort 6000 to a local COM/TTY port on the host computer. Real

COM mode supports up to eight simultaneous connections that enable multiple hosts to simultaneously collect

data from the same serial device.

One of the major conveniences of using Real COM mode is that it allows you to use software that was written

for pure serial communication applications. The Real COM driver intercepts data sent to the host’s COM port,

packs it into a TCP/IP packet, then redirects it through the host’s Ethernet card. At the other end of the

connection, the NPort 6000 accepts the Ethernet frame, unpacks the TCP/IP packet, and then transparently

sends the data through the serial port to the attached serial device.

section in Chapter 9, System Management Settings, for more details.

NPort 6000 Series Introducing Serial Port Operation Modes

4-4

Reverse Real COM Mode

Real COM mode will not work when the NPort 6000 is using a private IP address, or if the NPort 6000 is in a

dynamic IP address environment. In either of these cases, the remote host/server will not be able to connect

to the NPort 6000.

Private IP address application

Dynamic IP address application

Reserve Real COM mode is an innovative operation mode developed by Moxa. It allows NPort 6000 terminal

servers to achieve the same effect as Real COM mode, but without needing to apply for a public IP address. In

other words, Reverse Real COM mode can be used even if the NPort is using a private IP address, or is being

used in a dynamic IP address environment.

In Reserve Real COM mode, the NPort 6000 will actively initiate a connection to the remote host/server that is

listed in the destination IP field after it boots up.

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 6000 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 6000 serial port(s).

NPort 6000 Series Introducing Serial Port Operation Modes

4-5

Socket Applications

For socket applications, the NPort 6000 offers the following modes: TCP Server/Secure TCP Server, TCP Client/

Secure TCP Client, and UDP.

TCP Server and Secure TCP Server Modes

In TCP Server mode, the serial port on the NPort 6000 is assigned a port number which must not conflict with

any other serial port on the NPort 6000. The host computer initiates contact with the NPort 6000, establishes

the connection, and receives data from the serial device. This operation mode also supports up to eight

simultaneous connections, enabling multiple hosts to 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 6000, which is configured for TCP Server mode.

2. Once the connection is established, data can be transmitted in both directions between the host and the

NPort 6000.

TCP Server mode supports optional data encryption using SSL.

TCP Client and Secure TCP Client Modes

In TCP Client mode, the NPort 6000 can actively establish a TCP connection to a pre-defined host computer

when serial data arrives. After the data has been transferred, the NPort 6000 can automatically disconnect

from the host computer by using the Inactivity time settings.

As illustrated in the figure, data transmission proceeds as follows:

1. The NPort 6000, configured for TCP Client mode, requests a connection from the host.

2. Once the connection is established, data can be transmitted in both directions between the host and the

NPort 6000.

TCP Client mode includes optional data encryption using SSL.

UDP Mode

Compared to TCP communication, UDP is faster and more efficient. In UDP mode, you can unicast or

multi-unicast data from a serial device to one or multiple host computers; and the serial device can receive data

from one or multiple host computers. These traits make UDP mode especially suited for message display

applications.

Pair Connection and Secure Pair Connection Modes

In Pair Connection mode, two NPort 6000 servers work together to remove the 15-meter distance limitation

imposed by the RS-232 interface. One server is arbitrarily designated the master and the other as the slave—it

does not matter which is which as long as there is one of each. One server is connected from its RS-232 port

to the COM port of a PC or another type of computer, such as a handheld PDA that has a serial port; the other

server is connected to the serial device through its RS-232 port.

The two servers are then connected to each other over the network.

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 the properly configured NPort 6000 serial port to the MS-DOS computer’s serial

port, it is possible to use legacy software to transmit data over the Ethernet if the software is originally

designed to transmit data over a modem.

Terminal Applications

Terminal applications involve connecting terminals to UNIX or Windows servers over a network. A terminal

connects to the appropriately configured serial port the NPort 6000, and the NPort 6000 transmits information

to and from a UNIX or Windows server over the network through its Ethernet port. You may need to check with

your network administrator to determine the appropriate terminal mode. All terminal modes support fast keys

as used in many terminal applications.

Please refer to Chapter 7, Configuring Serial Port Operation Modes, for detailed information and configuration

instructions.

NPort 6000 Series Introducing Serial Port Operation Modes

Terminal ASCII Mode

Terminal ASCII mode can handle up to 8 sessions per port with the ability to switch between sessions on the

same terminal. This mode is used for text-based terminals with no file-transfer capability or encryption.

Terminal BIN Mode

Terminal BIN mode allows one session per port and is used for terminal applications that include file-transfer

features.

SSH Mode

SSH mode allows one session per port and is used for secure terminal applications that abide by the SSH

protocol.

Reverse Terminal Applications

Reverse terminal applications are similar to terminal applications in that they involve using the NPort 6000 to

manage the connection between a terminal and a server. The difference is that with reverse terminal

applications, the terminal is connected through the network and the server is connected through the serial port,

rather than the other way around. In practice, a reverse terminal session typically involves a network

administrator telnetting to a device that has a dedicated serial console port used specifically for configuration

purposes.

For example, many routers, switches, UPS units, and other devices (including the NPort 6000) have

Console/AUX or COM ports to which a terminal can be physically connected for console management. With the

NPort 6000, the device’s console port can be connected to a serial port on the NPort 6000, allowing a network

administrator to telnet to the device remotely through the network. Although modern network equipment

generally allows other options for remote configuration through the network, there are situations in which it is

necessary or desirable to configure a device by serial console (e.g., for security reasons, when using

older-generation equipment, or as a backup configuration method when the network is down).

NPort 6000 Series Introducing Serial Port Operation Modes

NPort 6000 reverse terminal modes allow the use of the NPort 6000 User Table or a RADIUS server for identity

verification purposes. Please refer to the Misc. Network Settings section in Chapter 9, System Management

Settings, for instructions on setting up the NPort 6000 User Table.

Reverse Telnet

Reverse Telnet mode is widely used for device management in control rooms. The system waits for a host on

the network to initiate a connection. Since TCP Server mode does not assist with conversion of CR/LF

commands, reverse terminal applications that require this conversion should use Reverse Telnet mode.

Reverse SSH

The NPort 6000 also offers a Reverse SSH mode so you can use SSH utilities such as PuTTY to connect to

remote servers.

Printer Modes

The NPort 6000’s Printer mode provides an excellent solution for banking and stock exchange services with

huge printing demands. Printer modes involve a network printer that is connected to a serial port on the NPort

6000, with a port number assigned to specify the printer’s location. Windows or UNIX hosts can access the

printer over the network in either RAW or LPD modes.

Please refer to Chapter 7, Configuring Serial Port Operation Modes, for detailed information and configuration

instructions.

Dial In/Out Modes

The NPort 6000 provides dial-in/dial-out access for ISPs and enterprises that need a remote access solution.

When a user at a remote site uses a PPP dial-up connection to access the NPort 6000, the NPort 6000 plays the

role of a dial-up server, but also ensures that the user has legal access to the network by verifying the user’s

identity with the NPort 6000 User Table or a RADIUS server. Please refer to the Misc. Network Settings section

in Chapter 9, System Management Settings, for instructions on setting up the NPort 6000 User Table.

The NPort 6000 supports PPP, SLIP, and Terminal modes for dial-in/dial-out access. Regardless of which

operating system is used, you will always be able to use standard PPP dial-up to establish a connection. The

NPort 6000 can also act as a router to connect serial ports to a WAN connection. Routing protocols (including

static, RIP I, and RIP II) can be adjusted to route different WAN connections.

Please refer to Chapter 7, Configuring Serial Port Operation Modes for detailed information and configuration

instructions.

Disabled Mode

You can disable any port on the NPort 6000 by setting the operation mode to Disabled.

ATTENTION

The examples and figures in this chapter use the NPort 6000 factory default IP address of 192.168.127.254.

If you have assigned a different IP address to your NPort 6000, be sure to adjust accordingly when following

these directions. Please refer to Chapter 3,

, for details on how to configure the

IP address.

ATTENTION

If you forget your password, the ONLY way to configure the NPort 6000 is by using the reset button to reset

all settings and load the factory defaults. If you have disabled the r

configuration, you may still use it to load the factory defaults within the first 60 seconds that the NPort 6000

is powered on.

Remember to back up your configuration by exporting it to a file. Your configuration can be easily restored by

importing the file to the NPort 6000. This will save time if you have forgotten the password and need to reload

the factory defaults.

Opening the Web Console

Open your web browser and enter 192.168.127.254 in the website address line. This is the default IP address

for the NPort 6000–if a new address has been assigned, enter the new address instead. Press ENTER to load

Web Console Navigation

On the NPort 6000 web console, the left panel is the navigation panel and contains an expandable menu tree

for navigating among the various settings and categories. When you click on a menu item in the navigation

panel, the main window will display the corresponding options for that item. Configuration changes can then be

made in the main window. For example, if you click on Network Configurations in the navigation panel, the

main window will show a page of network-related settings that you can configure.

You must click on the Submit button to keep your configuration changes. The Submit button will be located

at the bottom of every page that has configurable settings. If you navigate to another page without clicking the

Submit button, your settings will not be retained.

Changes will not take effect until they are saved and the NPort is restarted! You may complete this in

one step by clicking on the Save/Restart option after you submit a change. If you need to make several

changes before restarting, you may save your changes without restarting by selecting Save Configuration in

the navigation panel. If you restart the NPort 6000 without saving your configuration, the NPort 6000 will

discard all submitted changes.

Network Configuration

Basic Network Settings

You can access Basic Network Settings by expanding the Network Configuration item in the navigation

panel. Basic Network Settings is where you assign the NPort 6000 IP address, netmask, Gateway, and other IP

parameters.

PPPoE PPP over Ethernet, remote ISP-assigned IP address

IPv4 Address (default=192.168.127.254): Enter the IP address that will be assigned to your NPort 6000.

All ports on the NPort 6000 will share this IP address. An IP address is a number assigned to a network device

(such as a computer) as a permanent address on the network. Computers use the IP address to identify and

talk to each other over the network. Choose a proper IP address that is unique and valid in your network

environment.

Netmask (default=255.255.255.0): Enter the subnet mask. A subnet mask represents all of the network

hosts at one geographic location, in one building, or on the same local area network.

When a packet is sent out over the network, the NPort 6000 will use the subnet mask to check whether the

desired TCP/IP host specified in the packet is on the local network segment. If the address is on the same

network segment as the NPort 6000, a connection is established directly from the NPort 6000. Otherwise, the

connection is established through the given default gateway

Gateway: Enter the IP address of the gateway if applicable. A gateway is a network computer that acts as an

entrance to another network. Usually, the computers that control traffic within the network or at the local

Internet service provider are gateway nodes. The NPort 6000 needs to know the IP address of the default

gateway computer in order to communicate with the hosts outside the local network environment. For correct

gateway IP address information, consult the network administrator.

one second, the second try times out after three

seconds.

IPv4 DNS server 1: This is an optional field. If your network has access to a DNS server, you may enter the

DNS server’s IP address in this field. This allows the NPort 6000 to use domain names instead of IP addresses

to access hosts.

Domain Name System (DNS) is the way that Internet domain names are identified and translated into IP

addresses. A domain name is an alphanumeric name, such as www.moxa.com, which is easier to remember

than the numerical IP address. A DNS server is a host that translates this kind of text-based domain name into

the actual IP address used to establish a TCP/IP connection.

When the user wants to visit a particular website, the user’s computer sends the domain name (e.g.,

www.moxa.com) to a DNS server to request that website’s numerical IP address. When the IP address is

received from the DNS server, the user’s computer uses that information to connect to the website’s web

server

The NPort 6000 will play the role of a DNS client, in the sense that it will actively query the DNS server for the

IP address associated with a particular domain name. The following functions on the NPort 6000 web console

support the use of domain names in place of IP addresses: Time Server, Destination IP Address (in TCP Client

mode), Mail Server, SNMP Trap Server, Destination Address (in Pair Connection mode), Primary/Secondary

Host Address (in Terminal mode), RADIUS Server, TACACS+ Server and SMTP Server.

IPv4 implementations commonly use a dotted decimal representation of the network prefix known as the

subnet mask. A subnet mask is not used for IPv6. Only the prefix l

IPv4 DNS server 2: This is an optional field. The IP address of another DNS server can be entered in this field

for when DNS server 1 is unavailable.

PPPoE user account and PPPoE password: For dynamic broadband networks such as xDSL or cable modem,

users must enter the username and password that they received from their ISP to establish a network

connection. If a serial port on the NPort 6000 will be using PPPoE, enter the account name and password in

these fields.

WINS function (default=enable): Enable or disable the WINS (Windows Internet Naming Service) server.

WINS server: If a WINS Server is connected to the network, enter the WINS Server’s IP address in this field.

TCP/IP uses IP addresses to identify hosts, but users often use symbolic names, such as computer names. The

WINS Server, which uses NetBIOS over TCP/IP, contains a dynamic database to map computer names to IP

addresses.

What is IPv6?

IPv6 stands for Internet Protocol version 6. It is the second version of the Internet Protocol, introduced after

the first version, which is IPv4. The difference between the two versions is the length of the IP address. IPv4

uses 32-bit IP addresses; IPv6 uses 128-bit IP addresses. IPv4 is still the predominant protocol used over most

of the Internet.

IPv6 Configuration (default=Static): You can choose from three possible IP configuration modes.

Option Description

Auto IPv6 router assigned prefix

Step 1: NPort generates the Link local address automatically

Step 2: NPort sends the “Router solicitation” to the router to apply for an IP address.

2.1 Router assigns an IP address to NPort  Step 4

2.2 Router assigns the DHCPv6 Server to offer an IP address  Step3

2.3 Router has no response (e.g., router does not exist)  Step 3

IPv6 Address (default= Auto): Enter the IPv6 address that will be assigned to your NPort 6000. All ports on

the NPort 6000 will share this IPv6 address. An IPv6 address is a number assigned to a network device (such

as a computer) as a permanent address on the network. Computers use the IPv6 address to identify and talk

to each other over the network. Choose a proper IPv6 address that is unique and valid in your network

environment.

Prefix: The prefix is the part of the address that indicates the bits that have fixed values or are the bits of the

subnet prefix. Prefixes for IPv6 subnets, routes, and address ranges are expressed in the same way as

Classless Inter-Domain Routing (CIDR) notation for IPv4. An IPv6 prefix is written in address/prefix-length

notation. For example, 21DA:D3::/48 and 21DA:D3:0:2F3B::/64 are IPv6 address prefixes.

ength notation is supported.

IPv6 Gateway

Gateway: Enter the IPv6 address of the gateway if applicable. A gateway is a network computer that acts as

an entrance to another network. Usually, the computers that control traffic within the network or at the local

Internet service provider are gateway nodes. The NPort 6000 needs to know the IPv6 address of the default

gateway computer in order to communicate with the hosts outside the local network environment. For correct

gateway IPv6 address information, consult the network administrator.

IPv6 DNS server 2: This is an optional field. The IP address of another DNS server may be entered in this field

for when DNS server 1 is unavailable.

Connection Priority: This function should work with the NPort 6000 functions that use the domain name to

obtain the IP address of the remote host/server. For this kind of application, the NPort 6000 will ask for the IP

address of the remote host/server through the DNS, and the DNS will reply with both the IPv4 and IPv6 IP

addresses if both exist simultaneously in the remote host/server. For this reason, you need to define which one

has higher priority, IPv6 first (RFC 3484) or IPv4 first.

Applications that obtain the IP address from the domain name:

Application Time Server, DDNS, WINS, RADIUS Server, TACACS+ Server, Remote Syslog, E-

SNMP Tarp Alert.

OP Mode TCP Client, Reverse RealCOM, Pair connection, Terminal

LAN1 speed (default=Auto): You may configure the network speed for the built-in Ethernet connection on

the NPort 6000. IEEE 802.3 Ethernet supports auto negotiation of transfer speed. However, some

switches/hubs require that the communication speed be fixed at 100 Mbps or 10 Mbps. Note that there is no

option for configuring the network speed for the optional network modules for the NPort 6600 and 6450.

Advanced Network Settings

You can access Advanced Network Settings by expanding the Network Settings item in the navigation panel.

Advanced Network Settings is where the routing protocol and gratuitous ARP are configured.

What is RIP?

RIP (Routing Information Protocol) is a protocol used to manage routing information within a self-contained

network, such as a corporate LAN (Local Area Network) or an interconnected group of such LANs.

By using RIP, a gateway host with a router can send its entire routing table, which lists all the other hosts it

knows about, to its closest host every 30 seconds. The closest host in turn will pass this information on to its

neighbor, and so on, until all the hosts within the network have the same routing path information. This state

is known as network convergence. RIP uses a hop count as a way of determining network distance. (Other

protocols use more sophisticated algorithms that also include timing.) After receiving a packet headed for a

specific destination, a network host with a router uses the routing table information to determine the next host

to route the packet to.

RIP is considered an effective solution for small homogeneous networks. For larger, more complicated

networks, transmitting the entire routing table every 30 seconds can bog down the network with a lot of extra

traffic.

RIP 2 is an extension of RIP. Its purpose is to expand the amount of useful information contained in RIP packets

and to add security elements. RIP 2 has become the standard version of RIP, and the original RIP is no longer

used.

Routing Protocol: You may select which routing protocol, if any, your network will employ.

Gratuitous ARP: In some applications, you may need the NPort 6000 to send broadcast packets to update the

ARP table on the server. If you enable this function and set the send period, the NPort 6000 will send

periodically send broadcast packets at the specified time interval.

If your NPort 6000 series has expanded network modules, please refer to Chapter 6 for more information.

Setting up the DDNS

This section explains how to use the NPort 6000 with DDNS. When the NPort 6000 receives its IP address from

a DHCP (Dynamic Host Configuration Protocol) server, remote servers will be unable to access it using a fixed

IP address. With DDNS (Dynamic Domain Name Server), a remote server can access the NPort 6000 using its

domain name instead of its IP address.

Currently, the NPort 6000 supports DNS service as provided by DynDNS.org and No-IP.com. Taking NO-IP.com

as an example, you can easily register a host name for your own use for free. For detailed information, visit

http://www.noip.com/ or https://www.dyndns.com.

After you finish registering, you can fill in the host name, username, and password based on the service

provider you have chosen.

For example, if you have registered the host name “moxanport6000.noip.me” with NO-IP.com, you choose

“NO-IP.com” for the Server address, input “moxanport6000.noip.me” for host name, input your username and

password on “NP-IP.com”, and then click Submit. After doing so, when a remote server wants to access this

NPort 6000, it can simply use “moxanport6000.noip.me” instead of its IP address.

Configuring the Route Table

The route table is where you configure how the NPort 6000 will connect to an outside network.

You are allowed to have up to 32 entries in the route table. For each entry, you must provide information on the

gateway, destination, netmask, metric hops, and interface.

Gateway: This is the IP address of the next-hop router.

Destination: This is the host’s IP address or the network address of the route’s destination.

Netmask: This is the destination network’s netmask.

Metric: You may use this optional field to enter the number of hops from the source to the destination. This

allows the NPort 6000 to prioritize the routing of data packets if more than one router is available to reach a

given destination.

Iface: This is the network interface to which the packet must be sent.

Iface field must be set to that serial port for proper

Configuring Routes to the Internet

In this example, the Notebook PC dials into the NPort 6000 to request a connection to the Internet host at

210.48.96.9, which is not on the local network 203.67.6.xxx. This causes the NPort 6000 to act as a router

and send the datagram to the default next-hop router, 203.67.6.254. In this case, we should add the gateway

IP address of 203.67.6.254 to the routing table to handle hops to 210.48.96.9.

Generally, connections to the Internet are handled by assigning a gateway server in the network settings rather

than through the route table.

Configuring Routes to the Intranet

In this example, dial-in users can make requests to Intranet hosts 202.65.66.4 or 202.65.66.5, which are on

network 202.65.66.xxx (located outside network 203.67.6.xxx). You will need to add a route entry for the

next-hop router, 203.67.6.252 that delivers requests to network 202.65.66.xxx. The metric hop in this case

is 2 route hops.

Configuring Multiple-point Routes

For multilocation enterprises, NPort 6000 servers can be placed in different branch offices and used as both

multipoint routers and as remote access servers. When hosts (e.g., the Web/FTP and E-mail/News servers

shown in the figure) send requests to hosts on another network, such as 202.6.6.xxx or 201.2.2.xxx, the

corresponding NPort 6000 delivers the request to the other NPort 6000 on the remote end, 202.6.6.254 or

201.2.2.254, as the next-hop router..

For this example, assume that Modem 1 is connected to serial port 1, Modem 2 is connected to serial port 2, and

PPP source and destination IP addresses of modems 1, 2, 3, and 4 are as follows:

Source IP Destination IP Source IP Destination IP

Modem 1 203.67.6.250 202.6.6.250 Modem 3 202.6.6.250 203.67.6.250

Modem 2 203.67.6.249 201.2.2.249 Modem 4 201.2.2.249 203.67.6.249

In this case, you will need to add two entries to the routing table, as shown in the following figure.

Using Ethernet Redundancy

Setting up Ethernet Redundancy on your NPort 6000 network helps protect critical links against failure,

protects against network loops and achieves the ring topology, and keeps network downtime at a minimum.

The Ethernet Redundancy function allows the user to implement several NPort 6000 units into a ring topology

to provide a backup data transmission route in the event that a cable is inadvertently disconnected or damaged.

This is a particularly important feature for industrial applications, since it could take several minutes to

troubleshoot, such as locating the disconnected or severed cable. Several minutes of downtime could cause a

big loss in production and revenue. The NPort 6000 supports three different protocols for this Ethernet

redundancy function—Rapid Spanning Tree Protocol (IEEE-802.1w), Turbo Ring, and Turbo Ring 2.

NOTE

The STP protocol is part of the IEEE Std 802.1D, 1998 Edition bridge specification. The explanation given in

the following section uses bridge instead of NPort 6000.

The STP/RSTP Concept

Spanning Tree Protocol (STP) was designed to help reduce link failures on a network and provide protection

from loops. Networks that have a complicated architecture are prone to broadcast storms caused by

unintended loops on the network. The Moxa NPort 6000’s STP feature is disabled by default. To be completely

effective, you must enable RSTP/STP on every NPort 6000 connected to your network.

Rapid Spanning Tree Protocol (RSTP) implements the Spanning Tree Algorithm and Protocol defined by IEEE

Std 802.1w-2001. RSTP provides the following benefits:

• The topology of a bridged network will be determined much more quickly compared to STP.

• RSTP is backwards compatible with STP, making it relatively easy to deploy. For example:

 Defaults to sending 802.1D style BPDUs if packets with this format are received.

 STP (802.1D) and RSTP (802.1w) can operate on different ports of the same NPort 6000.

This feature is particularly helpful when the NPort 6000 ports are connected to older equipment, such as

legacy NPort 6000s.

You get essentially the same functionality with RSTP and STP. To see how the two systems differ, see the

“Differences between RSTP and STP” section in this chapter.

What is STP?

STP (802.1D) is a bridge-based system that is used to implement parallel paths for network traffic. STP uses a

loop-detection process to:

• Locate and then disable less efficient paths (i.e., paths that have a lower bandwidth).

• Enable one of the less efficient paths if the most efficient path fails.

The figure below shows a network made up of three LANs separated by three bridges. Each segment uses at

most two paths to communicate with the other segments. Since this configuration can give rise to loops, the

network will overload if STP is NOT enabled.

LAN 1

Bridge B

Bridge A

LAN 2

Bridge C

LAN 3

If STP is enabled, it will detect duplicate paths and prevent, or block, one of them from forwarding traffic. In the

following example, STP determined that traffic from LAN segment 2 to LAN segment 1 should flow through

Bridges C and A because this path has a greater bandwidth and is therefore more efficient.

LAN 1

What happens if a link failure is detected? As shown in next figure, the STP process reconfigures the network

so that traffic from LAN segment 2 flows through Bridge B.

LAN 1

LAN 2

LAN 3

STP will determine which path between each bridged segment is the most efficient and then assign a specific

reference point on the network. When the most efficient path has been identified, the other paths are blocked.

In the above three figures, STP first determined that the path through Bridge C was the most efficient, and as

a result, blocked the path through Bridge B. After the failure of Bridge C, STP reevaluated the situation and

opened the path through Bridge B.

How STP Works

When enabled, STP determines the most appropriate path for traffic through a network. The way it does this is

outlined in the sections below.

STP Requirements

Before STP can configure the network, the system must satisfy the following requirements:

• Communication between all the bridges. This communication is carried out using Bridge Protocol Data Units

(BPDUs), which are transmitted in packets with a known multicast address.

• Each bridge must have a Bridge Identifier that specifies which bridge acts as the central reference point, or

a Root Bridge, for the STP system—bridges with a lower Bridge Identifier are more likely to be designated

as the Root Bridge. The Bridge Identifier is calculated using the MAC address of the bridge and a priority

defined for the bridge. The default priority of the NPort 6000 series is 32768.

• Each port has a cost that specifies the efficiency of each link. The efficiency cost is usually determined by

the bandwidth of the link, with less efficient links assigned a higher cost.

NPort 6000 Series Module Settings

6-5

STP Calculation

The first step of the STP process is to perform calculations. During this stage, each bridge on the network

transmits BPDUs. The following items will be calculated:

• Which bridge should be the Root Bridge? The Root Bridge is the central reference point from which the

network is configured.

• The Root Path Costs for each bridge. This is the cost of the paths from each bridge to the Root Bridge.

• The identity of each bridge’s Root Port. The Root Port is the port on the bridge that connects to the Root

Bridge via the most efficient path. In other words, the port connected to the Root Bridge via the path with

the lowest Root Path Cost. The Root Bridge, however, does not have a Root Port.

• The identity of the Designated Bridge for each LAN segment. The Designated Bridge is the bridge with the

lowest Root Path Cost from that segment. If several bridges have the same Root Path Cost, the one with the

lowest Bridge Identifier becomes the Designated Bridge. Traffic transmitted in the direction of the Root

Bridge will flow through the Designated Bridge. The port on this bridge that connects to the segment is

called the Designated Bridge Port.

STP Configuration

After all the bridges on the network agree on the identity of the Root Bridge, and all other relevant parameters

have been established, each bridge is configured to forward traffic only between its Root Port and the

Designated Bridge Ports for the respective network segments. All other ports are blocked, which means that

they will not be allowed to receive or forward traffic.

STP Reconfiguration

Once the network topology has stabilized, each bridge listens for Hello BPDUs transmitted from the Root Bridge

at regular intervals. If a bridge does not receive a Hello BPDU after a certain interval (the Max Age time), the

bridge assumes that the Root Bridge, or a link between itself and the Root Bridge, has gone down. This will

trigger the bridge to reconfigure the network to account for the change. If you have configured an SNMP trap

destination, the first bridge to detect the change sends out an SNMP trap when the topology of your network

changes.

Differences between RSTP and STP

RSTP is similar to STP, but it includes additional information in the BPDUs that allows each bridge to confirm

that it has taken action to prevent loops from forming when it decides to enable a link to a neighboring bridge.

Adjacent bridges connected via point-to-point links will be able to enable a link without waiting to ensure that

all other bridges in the network have had time to react to the change. The main benefit of RSTP is that the

configuration decision is made locally rather than network-wide, allowing RSTP to carry out automatic

configuration and restore a link faster than STP.

STP Example

The LAN shown below has three segments, with adjacent segments connected using two possible links. The

various STP factors, such as Cost, Root Port, Designated Bridge Port, and Blocked Port are shown in the figure.

• Bridge A has been selected as the Root Bridge, since it was determined to have the lowest Bridge Identifier

on the network.

• Since Bridge A is the Root Bridge, it is also the Designated Bridge for LAN segment 1. Port 1 on Bridge A is

selected as the Designated Bridge Port for LAN Segment 1.

• Ports 1 of Bridges B, C, X, and Y are all Root Ports since they are the nearest to the Root Bridge, and

therefore have the most efficient path.

• Bridges B and X offer the same Root Path Cost for LAN segment 2. However, Bridge B was selected as the

Designated Bridge for that segment since it has a lower Bridge Identifier. Port 2 on Bridge B is selected as

the Designated Bridge Port for LAN Segment 2.

• Bridge C is the Designated Bridge for LAN segment 3, because it has the lowest Root Path Cost for LAN

Segment 3:

 The route through Bridges C and B costs 200 (C to B=100, B to A=100)

 The route through Bridges Y and B costs 300 (Y to B=200, B to A=100)

• The Designated Bridge Port for LAN Segment 3 is Port 2 on Bridge C.

Configuration Limits of RSTP/STP

The Spanning Tree Algorithm places limits on three of the configuration items described above:

[Eq. 1]: 1 sec ≦ Hello Time ≦ 10 sec

[Eq. 2]: 6 sec ≦ Max. Age ≦ 40 sec

[Eq. 3]: 4 sec ≦ Forwarding Delay ≦ 30 sec

These three variables are further restricted by the following two inequalities:

[Eq. 4]: 2 x (Hello Time + 1 sec) ≦ Max. Age ≦ 2 x (Forwarding Delay – 1 sec)

The NPort 6000’s firmware will alert you immediately if any of these restrictions are violated. For example,

setting

Hello Time = 5 sec, Max. Age = 20 sec, and Forwarding Delay = 4 sec does not violate Eqs. 1 through 3, but

does violate Eq. 4, since in this case,

2 x (Hello Time + 1 sec) = 12 sec, and 2 x (Forwarding Delay – 1 sec) = 6 sec.

You can remedy the situation in any number of ways. One solution is simply to increase the Forwarding Delay

value to at least 11 sec.

HINT: Take the following steps to avoid guessing:

Step 1: Assign a value to Hello Time and then calculate the leftmost part of Eq. 4 to get the lower limit of

Max. Age.

Step 2: Assign a value to Forwarding Delay and then calculate the rightmost part of Eq. 4 to get the upper

limit for Max. Age.

Step 3: Assign a value to Forwarding Delay that satisfies the conditions in Eq. 3 and Eq. 4.

Configuring Turbo Ring

The Turbo Ring Concept

Moxa developed the proprietary Turbo Ring protocol to optimize communication redundancy and achieve a

faster recovery time on the network. The Turbo Ring and Turbo Ring V2 protocols identify one NPort 6000 as

the master of the network and then automatically block packets from traveling through any of the network’s

redundant loops.

In the event that one branch of the ring gets disconnected from the rest of the network, the protocol

automatically readjusts the ring so that the part of the network that was disconnected can reestablish contact

with the rest of the network.

Initial setup of a “Turbo Ring” or “Turbo Ring V2” ring

1. Select any two ports as redundant ports.

2. Connect the redundant ports to form the Turbo Ring.

The user does not need to configure any of the NPort 6000 units as the master to use Turbo Ring or Turbo Ring

V2. If none of the NPort 6000 in the ring is configured as the master, then the protocol will automatically assign

master status to one of the NPort 6000 units. In fact, the master is only used to identify which segment in the

redundant ring acts as the backup path. In the following subsections, we explain how the redundant path is

selected for rings configured for Turbo Ring and Turbo Ring V2.

Determining the Redundant Path of a “Turbo Ring” Ring

In this case, the redundant segment (i.e., the segment that will be blocked during normal operation) is

determined by the number of EDS units that make up the ring and where the ring master is located

When the number of NPort 6000 units in the Turbo Ring is odd.

If there are 2N+1 NPort 6000 units (an odd number) in

the Turbo Ring, with NPort 6000 units and segments

labeled counterclockwise, then segment N+1 will serve

as the backup path.

For the example shown here, N=1, and therefore N+1=2.

Port Setting Basics

Each serial port on the NPort 6000 can be configured independently. To configure the operation mode and

settings for a port, expand Serial Port Configurations in the navigation panel; then expand the port that you

would like to configure. Individual port settings are grouped into five categories in the navigation panel:

Operation Modes, Communication Parameters, Data Buffering/Log, Modem Settings, and Cipher Settings.

Select Operation Modes in the navigation panel to select and configure the mode for each serial port. For

NPort 6000 models with two or more serial ports, you may use the checkboxes at the bottom of the window to

apply the settings to one or more ports.

Application: Select an application for the serial port from among the choices. Your application will determine

the modes that are available.

Mode: Once you have chosen an application, select the mode. The available configuration settings will vary

depending on the mode that you have selected.

TCP alive check time (default=7 min): This field specifies how long the NPort 6000 will wait for a response

to keep-alive packets before closing the TCP connection. The NPort 6000 checks connection status by sending

periodic keep-alive packets. If the remote host does not respond to the packet within the time specified in this

field, the NPort 6000 will force the existing TCP connection to close. For socket and device control modes, the

NPort 6000 will listen for another TCP connection from another host after closing the connection. If TCP alive

check time is set to 0, the TCP connection will remain open and will not send any keep-alive packets.

Max connection (default=1): This field is used if you need to receive data from different hosts

simultaneously. When set to 1, only one specific host can access this port of the NPort 6000, and the Real COM

driver on that host will have full control over the port. When set to 2 or greater, up to the specified number of

hosts’ Real COM drivers may open this port at the same time. When multiple hosts’ Real COM drivers open the

port at the same time, the COM driver only provides a pure data tunnel—no control ability. The serial port

parameters will use firmware settings instead of depending on your application program (AP).

Application software that is based on the COM driver will receive a driver response of “success” when the

software uses any of the Win32 API functions. The firmware will only send data back to the driver on the host.

Data will be sent first-in first-out when it enters the NPort 6000 from the Ethernet interface.

Once the PLC responds, the NPort 6000 will save that response to its buffer, assuming that the response is

correct and then send the command back to the originator of the command. The NPort 6000 can respond in

place of the PLC the next time it receives a request for the same command.

Response timeout (default=0 ms): This field specifies how long the NPort 6000 will wait for response data

through the serial port before sending the next command. The NPort 6000 sends the next command if there is

no response through the serial port for the time specified by the Response timeout. If this field is set to 0, the

Response timeout is essentially infinite, and the NPort 6000 will wait until the pre-command request is received

to send the next command.

Non-requested serial data (default=discard): Specifies how the NPort will handle data that is received

from a serial device that is not in response to a command. The NPort can either discard such data, forward the

data to the network host that sent the most recent request, or forward the data to all open host connections.

• Delimiter + 2: Data in the buffer will be transmitted after two additional bytes are received following the

• Strip Delimiter: Data in the buffer is first stripped of the delimiter before being transmitted.

Force transmit (default=0 ms): This parameter defines the size of a gap in serial communication the NPort

6000 will allow before packing the serial data in its internal buffer for network transmission.

As data is received through the serial port, it is stored by the NPort 6000 in its internal buffer. The NPort 6000

transmits data stored in the buffer over the TCP/IP network when the specified force transmit time is reached.

When set to 0, the force transmit time is disabled, and the NPort 6000 transmits data over the TCP/IP network

as soon as the serial data is received. At 1 to 65535, the TCP/IP protocol software will pack the serial data

received when there is a gap in serial communication that exceeds the specified force transmit time.

The optimal force transmit time depends on your application, but it must be at least larger than one character

interval within the specified baudrate. For example, let’s 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 the force transmit time to be larger than 8.3 ms, so in this case, it must be greater than or equal

to 10 ms.

If it is necessary to send a series of characters in the same packet, the serial device will need to send that series

of characters within the specified force transmit time, and the total length of data must be less than or equal

to the NPort 6000’s internal buffer size (1 KB per port).

Applying the above setting to NPort 6000 models with two or more serial ports, you may use the checkboxes

at the bottom of the window to apply the settings to one or more ports.

TCP alive check time (default=7 min): This field specifies how long the NPort 6000 will wait for a response

to keep-alive packets before closing the TCP connection. The NPort 6000 checks connection status by sending

periodic keep-alive packets. If the remote host does not respond to the packet within the time specified in this

field, the NPort 6000 will force the existing TCP connection to close. For socket and device control modes, the

NPort 6000 will listen for another TCP connection from another host after closing the connection. If TCP alive

check time is set to 0, the TCP connection will remain open even if there is no response to the keep-alive

packets.

TCP port (default=4001): This is the TCP port number assignment for the serial port on the NPort 6000. It

is the port number that the serial port uses to listen to connections and that other devices must use to contact

the serial port. To avoid conflicts with well-known TCP ports, the default is set to 4001.

is full. When a packet length between 1 and 1024 bytes is specified, data in the buffer will be sent as soon it

reaches the specified length.

Delimiter 1 and Delimiter 2 (default=None): When Delimiter 1 is enabled, the serial port will clear the

buffer and send the data to the Ethernet port when a specific character, entered in hex format, is received. A

second delimiter character may be enabled and specified in the Delimiter 2 field, so that both characters act as

is no incoming or outgoing data through the serial port for the specified Inactivity time. If this field is set to

0, the TCP connection is kept active until a connection close request is received.

Max connection (default=1): This field is used if you need to receive data from different hosts

simultaneously. When set to 1, only a single host may open the TCP connection to the serial port. When set to

2 or greater, up to the specified number of hosts may open this port at the same time. When multiple hosts

establish a TCP connection to the serial port at the same time, the NPort 6000 will duplicate the serial data and

transmit it to all the hosts. Ethernet data is sent on a first-in first-out basis to the serial port when data enters

the NPort 6000 from the Ethernet interface.

Ignore jammed IP (default=Disable): This option determines how the port will proceed if multiple hosts

are connected and one or more of the hosts stops responding as the port is transmitting data. If you select

Disable, the port will wait until the data has been transmitted successfully to all the hosts before transmitting

the next group of data. If you select Enable, the port will ignore the host that stopped responding and continue

data transmission to the other hosts.

Allow driver control (default=Disable): This option determines how the port will proceed if driver control

commands are received from multiple hosts that are connected to the port. If Disable is selected, driver

control commands will be ignored. If Enable is selected, control commands will be accepted, with the most

recent command received taking precedence.

Secure (default=Disable): If you select Enable, data sent through the Ethernet will be encrypted with SSL.

TCP port (default=4001): This is the TCP port number assignment for the serial port on the NPort 6000. It

is the port number that the serial port uses to listen to connections, and that other devices must use to contact

Response timeout (default=0 ms): This field specifies how long the NPort 6000 will wait for response data

through the serial port before sending the next command. The NPort 6000 sends the next command if there is

no response through the serial port for the time specified by the Response timeout. If this field is set to 0, the

Response timeout is essentially infinite, and the NPort 6000 will wait until the pre-command request is received

to send the next command.

Non-requested serial data (default=discard): Specifies how the NPort will handle data that is received

from a serial device that is not in response to a command. The NPort can either discard such data, forward the

data to the network host that sent the most recent request, or forward the data to all open host connections.

• Discard: Discard the data

Pair Connection Mode

Pair Connection mode can be used to remove the 15-meter distance limitation imposed by the RS-232 interface.

It establishes a connection between a serial port on one NPort 6000 server and another serial port on another

NPort 6000 server. One of the serial ports is connected to the COM port of a PC or another type of computer,

such as a handheld PDA that has a serial port. The other serial port is connected to the desired serial device.

The two NPort 6000 servers are then connected to each other with a crossover Ethernet cable, and both are

connected to the same LAN. In a more advanced setup, the two NPort 6000 servers communicate with each

other over a WAN (i.e., through one or more routers). In Pair Connection Mode, both data and modem control

signals (but not DCD signals) are transparently transferred between the two NPort 6000 servers.

Pair Connection Master Mode

When using Pair Connection mode, Pair Connection Master mode must be selected as the Operation mode

for one of the two serial ports involved, and Pair Connection Slave mode must be selected for the other serial

port. In effect, the serial port that is in Pair Connection Master mode will be acting as a TCP client, and the one

that is in Pair Connection Slave mode will be acting as a TCP server. In practice, it does not matter which port

is the master and which port is the slave.

a TCP connection from the remote Ethernet Modem or PC. Here IP address is the IP address of the remote

Ethernet modem or PC, and TCP port is the TCP port number of the remote Ethernet modem or PC. Once the

remote unit accepts this TCP connection, the NPort 6000 will send out the CONNECT baud signal via the serial

port and then enter data mode.

Dial-in

The NPort 6000 listens for a TCP/IP connection request from the remote Ethernet modem or host. The NPort

6000’s response depends on the ATS0 value, as follows.

ATS0=0: The NPort 6000 will temporarily accept the TCP connection and then send the RING signal out

through the serial port. The serial controller must reply with ATA within 2.5 seconds to accept the connection

request, after which the NPort 6000 enters data mode. If no ATA command is received, the NPort 6000 will

will automatically be set to 1.5 bits.

Parity (default=None): This field configures the parity parameter.

Flow control (default=RTS/CTS): This field configures the flow control type, including RTS/CTS, DTR/DSR,

Xon/Xoff, RTS Toggle* and None.

* The RTS Toggle function is used for RS-232 mode only. This flow control mechanism is achieved by toggling

the RTS pin in the transmission direction. When activated, data will be sent after the RTS pin is toggled ON for

the specified time interval. After data transmission is finished, the RTS pin will toggle OFF for the specified

time interval. RTS Toggle is not supported under RFC2217 mode.

s a special baudrate that is not listed, such as 500000 bps, you can select the Other

n 1.7% for all baudrates under 921600 bps.

8-3

FIFO (default=Enable): This field enables or disables the 128-byte FIFO buffer. The NPort 6000 provides FIFO

buffers for each serial port, for both the Tx and Rx signals. Note, however, that you should disable the port’s

FIFO setting if the attached serial device does not have a FIFO buffer of its own. This is because a serial device

that does not have its own buffer may not be able to keep up with data sent from the NPort’s FIFO buffer.

Interface (default=RS-232): You may configure the serial interface to RS-232, RS-422, RS-485 2-wire, or

RS-485 4-wire.

Port Data Buffering/Log

The NPort 6000 supports port buffering to prevent the loss of serial data when the Ethernet connection is down.

Port buffering can be used in TCP Server mode, TCP Client mode, and Pair Connection mode. For other modes,

the port-buffering settings will have no effect.

Port buffering enable (default=Disable): You may enable port buffering by setting this field to Enable.

Port buffering location (default=Memory(64K)): If port buffering is desired, use this setting to configure

whether the buffer is located in the system memory or in an optional installed SD card. Install and use an SD

card if a buffer size greater than 64 KB is desired. Note that optional SD cards are not supported on the NPort

6150.

Port buffering SD file size (default=1 Megabyte): Use this field to configure the size of the port buffer if

you have configured it to reside on an SD card. Note that optional SD cards are not supported on the NPort

6150.

Serial data logging enable (default=Disable): If this field is set to Enable, the NPort 6000 will store data

logs on the system RAM for all serial ports. Note that this data is not saved when the NPort 6000 is powered off.

Each serial port is allotted 64 KB to store that port’s log file.

Before making any adjustments to the time, first select the correct time zone and submit the change. The

console will display the real time according to the time zone. To modify the real-time clock, click on Modify

next to the Local time field. Once you submit the new time, the NPort 6000’s firmware will modify the GMT

time according to your time zone and local time settings.

Time server: The NPort 6000 uses SNTP (RFC-1769) for auto time calibration. You may enter a time server IP

address or domain name in this optional field. Once the NPort 6000 is configured with the correct time server

address, it will request time information from the time server every 10 minutes.

Accessible IP List

The NPort 6000 uses an IP address-based filtering method to control access to its serial ports.

The Accessible IP list allows you restricted network access to the NPort 6000. Access is controlled by IP address.

When the accessible IP list is enabled, a host’s IP address must be listed in order to have access to the NPort

6000. You may add a specific address or range of addresses by using a combination of IP address and netmask,

as follows:

To allow access to a specific IP address

Enter the IP address in the corresponding field; enter 255.255.255.255 for the netmask.

To allow access to hosts on a specific subnet

For both the IP address and netmask, use 0 for the last digit (e.g., 192.168.1.0 and 255.255.255.0).

To allow unrestricted access

Deselect the Enable the accessible IP list option.

Host Table

The Host Table may be used to simplify IP address entry on the NPort 6000 console by assigning a Host Name

to a Host IP Address. When you assign a Host Name to a Host IP Address, you may then use the Host Name for

some fields on the console rather than entering the IP address. Up to 16 entries can be stored on the Host

Table.

Firmware Upgrade

The NPort 6000’s firmware can be upgraded though the web console, serial console, or through NPort Search

Utility. If you have made any changes to your configuration, remember to save the configuration first before

upgrading the firmware. Please refer to Save Configuration later in this chapter for more information. Any

unsaved changes will be discarded when the firmware is upgraded. To upgrade the firmware, simply enter the

file name and click Submit. The latest firmware can be downloaded at www.moxa.com
