NPort IA5150/5250 Series User’s Manual Getting Started

Panel Layout

Connecting the Hardware

This section describes how to connect NPort IA5150/5250 to serial devices for first time testing purposes. We cover Wiring Requirements, Connecting the Power, Grounding NPort IA5150/5250 Series, Connecting to the Network, Connecting to a Serial Device, and LED Indicators.

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:

yUse 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.

yYou 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.

yKeep input wiring and output wiring separate.

yWhere 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 Ground) contact is the left most contact of the 7-pin power 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:

yThe Ethernet LED maintains a solid green color when connected to a 100 Mbps Ethernet network.

yThe Ethernet LED maintains a solid orange color when connected to a 10 Mbps Ethernet network.

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

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.

LED Indicators

The top panels of all NPort IA5150/5250 device servers have four LED indicators, as described in the following table.

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:

(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.

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

5.Type 1 to select IP address and then press Enter.

6.Use the Backspace key to erase the current IP address, type in the new IP address, and then press Enter.

7.Press any key to continue.

8.Type m and then press Enter to return to the main menu.

9.Type s and then press Enter to Save/Restart the system.

10. Type y and then press Enter to save the new IP address and restart NPort IA5150/5250.

Serial Console (19200, n, 8, 1)

You may use the RS-232 console port to set up the IP address for NPort IA5150/5250. We suggest using PComm Terminal Emulator, which is available free of charge as part of the PComm Lite program suite, to carry out the installation procedure, although other similar utilities may also be used.

ATTENTION

The Serial Console is an RS-232 port (port 1 for NPort IA5250).

Before you start to configure the NPort IA5150/5250 via serial console, turn off the power and connect the serial cable from NPort IA5150/5250 to your computer’s serial port.

1.Connect NPort IA5150/5250’s serial port 1 directly to your computer’s male RS-232 serial port.

2.From the Windows desktop click on Start Æ Programs Æ PComm Lite Æ Terminal Emulator.

3.When the PComm Terminal Emulator window opens, first click on the Port Manager menu item and select Open, or simply click on the Open icon.

4.The Property window opens automatically. From the Communication Parameter page, select the appropriate COM port for the connection, COM1 in this example, and 19200 for

Baud Rate, 8 for Data Bits, None for Parity, and 1 for Stop Bits.

5.From the Property window’s Terminal page, select ANSI or VT100 for Terminal Type and then click OK.

If you select Dumb Terminal as the terminal type, some of the console functions—especially the “Monitor” function—may not work properly.

6.Press the “ ` ” key continuously and then power on the NPort IA5150/5250.

7.NPort IA5150/5250 will automatically switch from data mode to console mode as it receives a continuous string of “ ` ”.

8.Input the password when prompted. Note that this page will only appear when the NPort IA5150/5250 has been set up for password protection.

9.Start configuring the IP address under Network Settings. Refer to step 4 in the Telnet Console section for the rest of the IP settings.

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.

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.

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.

ATTENTION

If you use other web browsers, remember to Enable the functions to “allow cookies that are stored on your computer” or “allow per-session cookies.”

NPort IA5150/5250 uses cookies only for “password” transmission.

ATTENTION

Refer to Chapter 3, “Initial IP Address Configuration,” to see how to configure the IP address. Examples shown in this chapter use the Factory Default IP address (192.168.127.254).

The NPort IA5150/5250 homepage will open. On this page, you can see a brief description of the Web Console’s nine function groups.

ATTENTION

If you can’t remember the password, the ONLY way to start configuring NPort IA5150/5250 is to load factory defaults by using the Reset button.

Remember to use NPort 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 IA5150/5250 by using the NPort Administrator Import function. Refer to Chapter 6 for more details about using the Export and Import functions.

ATTENTION

If your NPort IA5150/5250 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.

Basic Settings

Server name

This option is useful for specifying the location or application of different NPort IA5150/5250s.

Time

NPort IA5150/5250 has a built-in Real-Time Clock for time calibration functions. Functions such as Auto warning “Email” or “SNMP Trap” can add real-time information to their messages.

ATTENTION

First time users should select the time zone first. The Console will display the “real time” according to the time zone compared to GMT.

If you would like to modify the real time clock, select “Local time.” NPort IA5150/5250’s firmware will modify the GMT time according to the Time Zone.

Time zone

Click on the Modify button to open the Modify time settings window to input the correct local time.

Time server

NPort IA5150/5250 uses SNTP (RFC-1769) for auto time calibration.

Input the correct “Time server” IP address or domain name. Once NPort IA5150/5250 is configured with the correct Time server address, NPort IA5150/5250 will request time information from the “Time server” every 10 minutes.

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 IA5150/5250. The factory default for both Web console and Telnet console is Enable.

ATTENTION

If you disable both the “Web console” and “Telnet console,” you can still use NPort Administrator to configure NPort IA5150/5250 either locally or remotely over the network. Refer to Chapter 6 for more details.

Reset button protect

Options are No and Yes, with default = No.

NOTE: Select the Yes option to allow limited use of the Reset Button. In this case, the Reset Button can be used for only 60 seconds. I.e., 60 sec. after booting up, the Reset Button will be disabled automatically.

Network Settings

You must assign a valid IP address to NPort IA5150/5250 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 IA5150/5250 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.

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

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 IA5150/5250 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 IA5150/5250, a connection is established directly from the NPort IA5150/5250. Otherwise, the connection is established through the given default gateway.

Gateway

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 IA5150/5250 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.

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

When the user wants to visit a particular website, the computer asks a Domain Name System (DNS) server for the website’s correct IP address, and then the computer uses the response to 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 IA5150/5250’s DNS feature, you need to configure the DNS server. Doing so allows NPort IA5150/5250 to use a host’s domain name to access the host. NPort IA5150/5250 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 IA5150/5250 plays the role of DNS client, in the sense that the NPort IA5150/5250 will actively query the DNS server for the IP address associated with a particular domain name. NPort IA5150/5250 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.

Точную цифру назвать сложно, т.к. помимо самих данных в пакеты Ethernet включается дополнительная информация. Поэтому для простоты расчетов можно считать, что передаваемый трафик в 2 раза больше чем трафик по последовательному интерфейсу. Например, вы передаете 1000 бит данных в секунду на какой-то скорости по СОМ порту, значит трафик в Ethernet будет около 1000*2 = 2000 бит/с.
