NPort IA5150/5250 Series User’s Manual Getting Started

Wiring Requirements

ATTENTION

Safety First!

Be sure to disconnect the power cord before installing and/or wiring your NPort IA5150/5250 Series.

Wiring Caution!

Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes dictating the maximum current allowable for each wire size.

If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your equipment.

Temperature Caution!

Please take care when handling NPort IA5150/5250. When plugged in, NPort IA5150/5250’s internal components generate heat, and consequently the casing may feel hot to the touch.

You should also heed the following:

y 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.

y 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.

y Keep input wiring and output wiring separate. y 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 NPort IA5150/5250’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.

Grounding NPort IA5150/5250 Series

Grounding and wire routing helps limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw to the grounding surface prior to connecting devices.

ATTENTION

This product is intended to be mounted to a well-grounded mounting surface such as a metal panel.

SG: The Shielded Ground (sometimes called Protected

terminal block connector when viewed from the angle shown here. Connect the SG wire to an appropriate grounded metal surface.

Connecting to the Network

Connect one end of the Ethernet cable to NPort IA5150/5250’s 10/100M Ethernet port and the other end of the cable to the Ethernet network. If the cable is properly connected, NPort IA5150/5250 will indicate a valid connection to the Ethernet in the following ways:

y The Ethernet LED maintains a solid green color when connected to a 100 Mbps Ethernet

network.

y The Ethernet LED maintains a solid orange color when connected to a 10 Mbps Ethernet

network.

y The Ethernet LED will flash when Ethernet packets are being transmitted or received.

NOTE

NPort IA5150 and NPort IA5250 each have 2 Ethernet ports, which can be used to create an open chain of NPort IA device servers. You must be careful not to connect the Ethernet ports of the two device servers at the ends of the chain. In other words, NPort IA does NOT support a closed chain.

Connecting to a Serial Device

Connect the serial data cable between NPort IA5150/5250 and the serial device. Serial data cables are optional accessories for NPort.

Chapter 3 Initial IP Address Configuration

When setting up your NPort IA5150/5250 for the first time, the first thing you should do is configure the IP address. This chapter introduces the methods that can be used to configure the device server’s IP address. Select one of the initial IP Address configuration methods to

configure NPort IA5150/5250’s IP Address. For more details about network settings, see the Network Settings section from Chapter 5, Web Console Configuration.

The following topics are covered in this chapter:

 Initializing NPort IA5150/5250’s IP Address  Factory Default IP Address  NPort IA5150/5250 Administration Suite  ARP  Telnet Console  Serial Console (19200, n, 8, 1)

NPort IA5150/5250 Series User’s Manual Initial IP Address Configuration

Initializing NPort IA5150/5250’s IP Address

1. Determine whether your NPort IA5150/5250 needs to use a Static IP or Dynamic IP (either DHCP or BOOTP application).

2. If NPort IA5150/5250 is used in a Static IP environment, you can use NPort IA5150/5250 Administration Suite, ARP, Web Console, Telnet Console, or Serial Console to configure the new IP address.

3. If NPort IA5150/5250 is used in a Dynamic IP environment, you can use NPort IA5150/5250 Administration Suite, Web Console, Telnet Console, or Serial Console to configure NPort IA5150/5250 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 IA5150/5250 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 IA5150/5250.

Factory Default IP Address

NPort IA5150/5250 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 IA5150/5250 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 IA5150/5250 Administration Suite

NPort IA5150/5250 Administration Suite consists of some useful utility programs that are used to configure and manage your NPort IA5150/5250.

See Chapter 5 for details on how to install NPort IA5150/5250 Administration Suite, and how to use this suite of useful utilities to set up IP addresses and configure your NPort IA5150/5250 Series serial device servers.

ARP

You can make use of the ARP (Address Resolution Protocol) command to set up an IP address for your NPort IA5150/5250. The ARP command tells your computer to associate the NPort IA5150/5250’s MAC address with the intended IP address. You must then use Telnet to access the NPort IA5150/5250, at which point the device server’s IP address will be reconfigured.

ATTENTION

In order to use this setup method, both your computer and NPort IA5150/5250 must be connected to the same LAN. Or, you may use a cross-over Ethernet cable to connect the NPort IA5150/5250 directly to your computer’s Ethernet card. Before executing the ARP command, your NPort IA5150/5250 must be configured with the factory default IP address (192.168.127.254), and your computer and the NPort IA must be on the same subnet.

3-2

NPort IA5150/5250 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 IA5150/5250 from your network administrator.

2. Obtain NPort IA5150/5250’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 IA5150/5250. (Be sure to use the actual IP address and MAC address for your NPort IA5150/5250.)

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 IA5150/5250 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 IA5150/5250’s IP address. This can be done using Telnet.

ATTENTION

Figures in this chapter were generated using NPort IA5250.

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 IA5150/5250 is password protected.

NPort IA5150/5250 Series User’s Manual Choosing the Proper Operation Mode

Overview

NPort IA5150/5250 Serial Device Servers network-enable traditional RS-232/422/485 devices, in which a Serial Device Server is a tiny computer equipped with a CPU, real-time OS, and TCP/IP protocols that can bi-directionally translate data between the serial and Ethernet formats. Your computer can access, manage, and configure remote facilities and equipment over the Internet from anywhere in the world.

Traditional SCADA and data collection systems rely on serial ports (RS-232/422/485) to collect data from various kinds of instruments. Since NPort IA5150/5250 Serial Device Servers network-enable instruments equipped with an RS-232/422/485 communication port, your SCADA and data collection system will be able to access all instruments connected to a standard TCP/IP network, regardless of whether the devices are used locally or at a remote site.

NPort IA5150/5250 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 IA5150/5250 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 unicast or multicast of data to only one IP or groups of IP addresses.

Real COM Mode

NPort IA5150/5250 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 IA5150/5250’s serial port to a local COM/TTY port on the host computer. Real COM Mode also supports up to 4 simultaneous connections, so that multiple hosts can collect data from the same serial device at the same time.

NPort IA5150/5250 Series User’s Manual Choosing the Proper Operation Mode

ATTENTION

The driver used for Real COM Mode comes with the NPort IA5150/5250 NPort Administrator. The driver is installed automatically on your computer when you install NPort IA5150/5250 Administration Suite.

One of the major conveniences of using Real COM Mode is that Real COM Mode allows users to continue using RS-232/422/485 serial communications software that was written for pure serial communications applications. The driver intercepts data sent to the host’s COM port, packs it into a TCP/IP packet, and then redirects it through the host’s Ethernet card. At the other end of the connection, the NPort IA5150/5250 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 IA5150/5250’s serial ports.

ATTENTION

Real COM Mode allows several hosts to have access control over the same NPort IA5150/5250. The driver that comes with your NPort IA5150/5250 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.

TCP Server Mode

In TCP Server mode, NPort IA5150/5250 is configured with a unique IP:Port address on a TCP/IP network. NPort IA5150/5250 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 IA5150/5250 configured for TCP Server Mode.

2. Once the connection is established, data can be transmitted in both directions—from the host to the NPort IA5150/5250, and from the NPort IA5150/5250 to the host.

TCP Client Mode

In TCP Client mode, NPort IA5150/5250 can actively establish a TCP connection to a pre-defined host computer when serial data arrives.

After the data has been transferred, NPort IA5150/5250 can automatically disconnect from the host computer by using the TCP alive check time or Inactivity time settings. Refer to Chapter 5 for more details.

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

1. The NPort IA5150/5250 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 IA5150/5250, and from the NPort IA5150/5250 to the host.

UDP Mode

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

Pair Connection Mode

Pair Connection Mode employs two NPort IA5150/5250 in tandem, and can be used to remove the 15-meter distance limitation imposed by the RS-232 interface. One NPort IA5150/5250 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 IA5150/5250. The two NPort IA5150/5250 units are then connected to each other with a cross-over Ethernet cable, both are connected to the same LAN, or in a more advanced setup, they communicate with each other over a WAN (i.e., through one or more routers). Pair Connection Mode transparently transfers both data and modem control signals (although it cannot transmit the DCD signal) between the two NPorts.

Ethernet Modem Mode

Ethernet Modem Mode is designed for use with legacy operating systems, such as MS-DOS, that do not support TCP/IP Ethernet. By connecting one of NPort IA5150/5250’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.

Reverse Telnet Mode

Console management is commonly used by connecting to Console/AUX or COM ports of routers, switches, and UPS units. Rtelnet works the same as RAW mode in that only one TCP port is listened to after booting up. The system then waits for a host on the network to initiate a connection. The difference is that the RAW mode does not provide the conversion function provided by Telnet. If the connected devices need to use the CR/LF conversion function when controlling, then users must choose Rtelnet mode. In addition, since NPort IA5150/5250’s Rtelnet mode is widely used in device management in Telecommunication control rooms, managers for remote hosts can also use a Local User Table or RADIUS to identity verification methods.

Disabled Mode

When the Operation Mode for a particular port is set to Disabled, that port will be disabled.
