Initial IP Address Configuration

When setting up your NPort 5110 for the first time, you should first configure the IP address. This chapter introduces the method to configure the device server’s IP address. For more details about network settings, see the Network Settings section from Chapter 5, Web Console Configuration.

This chapter includes the following sections:

!Initializing NPort 5110’s IP Address

!Factory Default IP Address

!ARP

!Telnet Console

!Serial Console (19200, n, 8, 1)

NPort 5110 Series User’s Manual

Initial IP Address Configuration

Initializing NPort 5110’s IP Address

1.Determine whether your NPort 5110 needs to use a Static IP or Dynamic IP (either DHCP or BOOTP application).

2.If NPort 5110 is used in a Static IP environment, you can use NPort 5110 Administration Suite, ARP, Web Console, Telnet Console, or Serial Console to configure the new IP address.

3.If NPort 5110 is used in a Dynamic IP environment, you can use NPort 5110 Administration Suite, Web Console, Telnet Console, or Serial Console to configure NPort 5110 to get an IP address dynamically with DHCP, DHCP/BOOTP, or BOOTP.

ATTENTION

Consult your network administrator on how to reserve a fixed IP address for your NPort 5110 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 5110.

Factory Default IP Address

NPort 5110 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 5110 applications that require sending data over a public network, such as the Internet, require setting up the server with a valid public IP address, which can be leased from a local ISP.)

NPort 5110 Administration Suite

NPort 5110 Administration Suite consists of some useful utility programs that are used to configure and manage your NPort 5110s.

See Chapter 5 for details on how to install NPort 5110 Administration Suite, and how to use this suite of useful utilities to set up IP addresses and configure your NPort 5110 serial device servers.

ARP

You can make use of the ARP (Address Resolution Protocol) command to set up an IP address for your NPort 5110. The ARP command tells your computer to associate the NPort 5110’s MAC address with the intended IP address. You must then use Telnet to access the NPort 5110, at which point the device server’s IP address will be reconfigured.

ATTENTION

In order to use the ARP setup method, both your computer and NPort 5110 must be connected to the same LAN. Or, you may use a cross-over Ethernet cable to connect the NPort 5110 directly to your computer’s Ethernet card. Your NPort 5110 must be configured with the factory default IP address—192.168.127.254—before executing the ARP command, as described below.

3-2

NPort 5110 Series User’s Manual

Initial IP Address Configuration

Take the following steps to use ARP to configure the IP address:

1.Obtain a valid IP address for your NPort 5110 from your network administrator.

2.Obtain NPort 5110’s MAC address from the label on its bottom panel.

3.Execute the ‘arp -s’ command from your computer’s MS-DOS prompt by typing:

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

This is where 192.168.200.100 is the new IP address and 00-90-E8-xx-xx-xx is the MAC address for your NPort 5110. You will need to change both numbers, as described above in items 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 5110 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 5110’s IP address. This can be done using Telnet.

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 5110 is password protected.

Choosing the Proper Operation Mode

Overview

NPort 5110 Serial Device Servers are used to network-enable traditional RS-232 devices. A Serial Device Server is a tiny computer equipped with a CPU, real-time OS, and TCP/IP protocols that can bi-directionally transfer 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) to collect data from various kinds of instruments. Since NPort 5110 Serial Device Servers network-enable instruments equipped with an RS-232 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 5110 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 5110 also comes with a Real COM/TTY driver that transmits all serial signals intact. This means that your existing COM/TTY-based software can be preserved, without needing to invest in additional software.

Three different Socket Modes are available: TCP Server, TCP Client, and UDP Server/Client. The main difference between the TCP and UDP protocols is that TCP guarantees delivery of data by requiring the recipient to send an acknowledgement to the sender. UDP does not require this type of verification, making it possible to offer speedier delivery. UDP also allows data to be unicast or multicast to only one IP or to different groups of IP addresses.

TCP Server Mode

In TCP Server mode, NPort 5110 is configured with a unique IP:Port address on a TCP/IP network. NPort 5110 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 5110 configured for TCP Server Mode.

2.Once the connection is established, data can be transmitted in both directions—from the host to the NPort 5110, and from the NPort 5110 to the host.

TCP Client Mode

In TCP Client mode, NPort 5110 can actively establish a TCP connection to a pre-defined host computer when serial data arrives.

After the data has been transferred, NPort 5110 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.

Data transmission proceeds as follows:

1.The NPort 5110 configured for TCP Client Mode requests a connection from the host.

2.Once the connection is established, data can be transmitted in both directions—from the host to the NPort 5110, and from the NPort 5110 to the host.

4-2

NPort 5110 Series User’s Manual

Choosing the Proper Operation Mode

UDP Mode

Compared to TCP communication, UDP is faster and more efficient. In UDP mode, you can unicast or multicast data from the serial device to one or multiple host computers, and the serial device can also receive data from one or multiple host computers, making this mode ideal for message display applications.

Real COM Mode

NPort 5110 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 5110 port to a local COM port on the host computer. This operation mode also supports up to 4 simultaneous connections, so that multiple hosts can collect data from the same serial device at the same time.

ATTENTION

The driver used for Real COM Mode is installed automatically on your computer when you install NPort 5110 Administration Suite.

One of the major conveniences of using Real COM Mode is that Real COM Mode allows users to continue using RS-232 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 5110 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 5110’s serial ports.

ATTENTION

Real COM Mode allows several hosts to have access control of the same NPort 5110. The driver that comes with your NPort 5110 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.

Pair Connection Mode

Pair Connection Mode employs two NPort 5110 device servers in tandem, and can be used to remove the 15-meter distance limitation imposed by the RS-232 interface. One NPort 5110 is connected from its RS-232 port to the COM port of a PC or other type of computer, such as hand-held PDAs that have a serial port, and the serial device is connected to the RS-232 port of the other NPort 5110. The two NPort 5110 are then connected to each other with a cross-over Ethernet cable, both are connected to the same LAN, or in a more advanced setup, they communicate with each other over a WAN (i.e., through one or more routers). Pair Connection Mode transparently transfers both data and modem control signals (although it cannot transmit the DCD signal) between the two NPorts.

4-3

NPort 5110 Series User’s Manual

Choosing the Proper Operation Mode

Ethernet Modem Mode

The Ethernet Modem operation mode is designed for use with legacy operating systems, such as MS-DOS, that do not support TCP/IP Ethernet. By connecting one NPort 5110’s serial port to the MS-DOS computer’s serial port, it is possible to use legacy software originally designed to transmit data via modem, but now transmit the data over the Ethernet.

If you can’t remember the password, the ONLY way to start configuring NPort 5110 is to load factory defaults by using the Reset button located near the NPort 5110’s RJ45 Ethernet port.Remember to use Windows Administrator to export the configuration file when you have finished the configuration. After using the Reset button to load factory defaults, your configuration can be easily reloaded into NPort 5110 by using the Windows Administrator Import function.If your NPort 5110 application requires using password protection, you must enable the cookie function in your browser. If the cookie function is disabled, you will not be allowed to enter the Web Console Screen.

Web/Telnet Console

The “Disable” option for “Web Console” and “Telnet Console” is included for security reasons. In some cases, you may want to Disable one or both of these console utilities as an extra precaution to prevent unauthorized users from accessing your NPort 5110. The factory default for both Web console and Telnet console is Enable.

Network Settings

You must assign a valid IP address to NPort 5110 before it will work in your network environment. Your network system administrator should provide you with an IP address and related settings for your network. The IP address must be unique within the network (otherwise, NPort 5110 will not have a valid connection to the network). First time users can refer to Chapter 3, “Initial IP Address Configuration,” for more information.

You can choose from four possible “IP configuration” modes—Static, DHCP, DHCP/BOOTP, and BOOTP—located under the web console screen’s IP configuration drop-down box.

IP configuration

Method	Function Definition
Static	User defined IP address, Netmask, Gateway.
DHCP	DHCP Server assigned IP address, Netmask, Gateway, DNS, and Time
	Server
DHCP/BOOTP	DHCP Server assigned IP address, Netmask, Gateway, DNS, and Time
	Server, or BOOTP Server assigned IP address (if the DHCP Server does not
	respond)
BOOTP	BOOTP Server assigns IP address

	IP address
	Setting	Factory Default	Necessity
	E.g., 192.168.1.1	192.168.127.254	Required
	(IP addresses of the form x.x.x.0 and
	x.x.x.255 are invalid.)

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 which is unique and valid in your network environment.

Netmask

Setting	Factory Default	Necessity
E.g., 255.255.255.0	255.255.255.0	Required

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 5110 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 5110, a connection is established directly from the NPort 5110. Otherwise, the connection is established through the given default gateway.

Gateway

Setting	Factory Default	Necessity
E.g., 192.168.1.1	None	Optional

A gateway is a network gateway 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. NPort 5110 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.

IP configuration

Setting	Factory Default	Necessity
Static	Static	Required
DHCP
DHCP/BOOTP
BOOTP

ATTENTION

In Dynamic IP environments, the firmware will retry 3 times every 30 seconds until network settings are assigned by the DHCP or BOOTP server. The Timeout for each try increases from 1 second, to 3 seconds, to 5 seconds.If the DHCP/BOOTP Server is unavailable, the firmware will use the default IP address (192.168.127.254), Netmask, and Gateway for IP settings.

DNS server 1 / DNS server 2

Setting	Factory Default	Necessity
E.g., 192.168.1.1	None	Optional
(IP addresses of the form x.x.x.0 and
x.x.x.255 are invalid.)

connect to the web server. DNS is the way that Internet domain names are identified and translated into IP addresses. A domain name is an alphanumeric name, such as moxa.com, that it is usually easier to remember. A DNS server is a host that translates this kind of text-based domain name into the numeric IP address used to establish a TCP/IP connection.

In order to use NPort 5110’s DNS feature, you need to configure the DNS server. Doing so allows NPort 5110 to use a host’s domain name to access the host. NPort 5110 provides DNS server 1 and DNS server 2 configuration items to configure the IP address of the DNS server. DNS Server 2 is included for use when DNS sever 1 is unavailable.

NPort 5110 plays the role of DNS client, in the sense that the NPort 5110 will actively query the DNS server for the IP address associated with a particular domain name. NPort 5110 functions that support domain name are Time server, Destination IP Address in TCP Client mode, Mail Server, SNMP trap server, and Auto report to IP.

SNMP Settings

Community name

Setting	Factory Default	Necessity
1 to 39 characters	public	Optional
(E.g., Support, 886-89191230 #300)

A community name is a plain-text password mechanism that is used to weakly authenticate queries to agents of managed network devices.

Contact

Setting	Factory Default	Necessity
1 to 39 characters	None	Optional
(E.g., Support, 886-89191230 #300)

The SNMP contact information usually includes an emergency contact name and telephone or pager number.

Location

Setting	Factory Default	Necessity
1 to 39 characters	None	Optional
(E.g., Floor 1, office 2)

Specify the location string for SNMP agents such as NPort 5110. This string is usually set to the street address where the NPort 5110 is physically located.

IP Address Report

When NPort 5110 products are used in a dynamic IP environment, users must spend more time with IP management tasks. For example, if NPort 5110 works as a server (TCP or UDP), then the host, which acts as a client, must know the IP address of the server. If the DHCP server assigns a new IP address to NPort 5110, the host must have some way of determining NPort 5110’s new IP address.

NPort 5110 products help out by periodically reporting their IP address to the IP location server, in case the dynamic IP has changed. The parameters shown below are used to configure the Auto IP report function. There are two ways to develop an “Auto IP report Server” to receive NPort 5110’s Auto IP report.

1.Use Device Server Administrator’s IP Address Report function.

2.“Auto IP report protocol”, which can automatically receive the Auto IP report on a regular basis, is also available to help you develop your own software. Refer to Appendix E for the “Auto IP report protocol”.
