Panel Layout

Connecting the Hardware

This section describes how to connect NPort W2250/2150 Series to serial devices for first time

testing purposes. We cover Wiring Requirements, Connecting the Power, Connecting to the

Network, Connecting to a Serial Device, and LED Indicators.

Wiring Requirements

Safety First!

Be sure to disconnect the power cord before installing and/or wiring your device.

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 device. When plugged in, device’s internal components generate

heat, and consequently the casing may feel hot to the touch.

You should also pay attention to the following items:

 Use separate paths to route wiring for power and devices. If power wiring and

device wiring paths must cross, make sure the wires are perpendicular at the

intersection point.

NOTE: Do not run signal or communication wiring and power wiring in the

same wire conduit. To avoid interference, wires with different signal

characteristics should be routed separately.

 You can use the type of signal transmitted through a wire to determine which

wires should be kept separate. The rule of thumb is that wiring that shares

similar electrical characteristics can be bundled together.

 Keep input wiring and output wiring separate.

Where necessary, it is strongly advised that you label wiring to all devices in the system

Connecting the Power

Connect the 12-48 VDC power line with NPort W2250/2150’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.

Connecting to the Network

Connect one end of the Ethernet cable to NPort W2250/2150’s 10/100M Ethernet port and

the other end of the cable to the Ethernet network. If the cable is properly connected, NPort

W2250/2150 will indicate a valid connection to the Ethernet in the following ways:

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

Mbps Ethernet network.

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

Mbps Ethernet network.

 The Ethernet LED will flash when Ethernet packets are being transmitted or

received.

Connecting to a Serial Device

Connect the serial data cable between NPort W2250/2150 and the serial device. Serial data

cables are optional accessories for NPort W2250/2150. Refer to Chapter 1 under Optional

Accessories for information on the RJ45-to-DB25 and RJ45-to-DB9 cables.

Chapter 3 Initial IP Address Configuration

When setting up your NPort W2250/2150 for the first time, the first thing you should do is configure the IP

address. This chapter introduces the method to configure the device server’s IP address. Select one of the

initial IP Address configuration methods to configure NPort W2250/2150’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:

 Installation Procedure for First Time User

 Factory Default IP Address

 ARP

 Telnet Console

 Serial Console (19200, n, 8, 1)

Installation Procedure for First Time User

STEP 1: After removing NPort W2250 from the box, the first thing using a cross-over Ethernet

cable connect directly to your computer’s Ethernet port.

STEP 2: Attaching the power adaptor

STEP 3: Connect NPort W2250’s serial port to a serial device.

STEP 4: Use Web console to configure the NPort W2250 via Ethernet port.

Note: Recommend to use web console for configuration. About how to use web console ,please

refer to Chapter 5.

Note: Only one Network Interface work at the same time.

If Ethernet Link up, Disable WLAN, Only Ethernet port can be used.

If Ethernet Link down, Disable Ethernet, Only WLAN can be used.

Factory Default IP Address

NPort W2250 products are configured with the following default IP address:

LAN: Default setting is static IP, 192.168.126.254/255.255.255.0, If Ethernet port cant' get IP

from DHCP, IP address return to 192.168.126.254/255.255.255.0

WLAN: Default setting is static IP, 192.168.127.254/255.255.255.0, If WLAN port cant' get

IP from DHCP, IP address return to

192.168.127.254/255.255.255.0

Only one interface allow to use DHCP settings

Note: If you have changed the IP address and forget it later. You can push the reset button of

the W2250 hardware, the IP will return to the default IP address.

ARP

You can make use of the ARP (Address Resolution Protocol) command to set up an IP address for

your NPort W2250/W2150. The ARP command tells your computer to associate the NPort

W2250/W2150’s MAC address with the intended IP address. You must then use Telnet to access

the NPort W2250/W2150, at which point the device server’s IP address will be reconfigured.

This function only apply to Ethernet port.

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

1. Obtain a valid IP address for your NPort W2250/W2150 from your network administrator.

2. Obtain NPort W2250/W2150’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 W2250/W2150. 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

W2250/W2150 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

1. From the Windows desktop, click on Start and then select Run

2. Type telnet 192.168.126.254 (Default IP) in the Open text input box, and then click OK.

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 W2250 is

password protected.

3. Type 2 to select Network settings, and then press Enter

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

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

press Enter.

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

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

8. Type y and then press Enter to save the new IP address and restart NPort W2250/W2150.

Serial Console (19200, n, 8, 1)

You may use the RS-232 console port to set up the IP address for NPort W2250/W2150. We

suggest using PComm Terminal Emulator, which is available free of charge as part of the PComm

Lite program suite (found on the Software CD that comes with the product), to carry out the

installation procedure, although other similar utilities may also be used.

Before you start to configure the NPort W2250/W2150 via serial console, turn off the power and

connect the serial cable from NPort W2250/W2150 to your computer’s serial port.

1. Connect NPort W2250/W2150’s serial port 1 directly to your computer’s male RS-232 serial

port.

2. From the Windows desktop click on Start  Programs  PComm Lite  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 W2250/W2150.

7. NPort W2250/W2150 will receive the “ ` ” string continuously and then auto switch from data

mode to console mode.

8. Input the password when prompted. Note that this page will only appear when the NPort

W2250/W2150 has been set up for password protection.

9.Start configuring the IP address under Network Settings. Refer to the Telnet Console section

for the rest of the IP settings.

Chapter 4 Choosing the Proper Operation Mode

In this section, we describe the various NPort 5200 operation modes. The options include an

operation mode that uses a driver installed on the host computer, and operation modes that rely

on TCP/IP socket programming concepts. After choosing the proper operation mode in this

chapter, refer to Chapter 5 for detailed configuration parameter definitions.

 Overview

 TCP Server Mode

 TCP Client Mode

 UDP Mode

 Real COM Mode

Overview

NPort 5200 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 5200 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 5200 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 5200 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.

Pictures in this Chapter will use NPort 5400 series as an example.

TCP Server Mode

In TCP Server mode, NPort 5200 is configured

with a unique IP:Port address on a TCP/IP

network. NPort 5200 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

5200 configured for TCP Server Mode.

2. Once the connection is established, data can

be transmitted in both directions—from the

host to the NPort 5200, and from the NPort

5200 to the host.

TCP Client Mode

In TCP Client mode, NPort 5200 can

actively establish a TCP connection to a

pre-defined host computer when serial data

arrives.

After the data has been transferred, NPort

5200 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 5200 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

5200, and from the NPort 5200 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.

Real COM Mode

NPort 5200 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 5200’s serial port

to a local COM/TTY port on the host

computer.

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 5200 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 5200’s serial ports.

Real COM Mode allows several hosts to have access control of the same NPort 5200. The driver

that comes with your NPort 5200 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.

Chapter 5 Web Console Configuration

The Web Console is the most user-friendly method available to configure NPort 5200 Series. This

chapter introduces the Web Console function groups and function definitions.

4. The NPort 5200 homepage will open. On this page, you can see a brief description of the Web

Console’s nine function groups.

If you can’t remember the password, the ONLY way to start configuring NPort 5200 is to load

factory defaults by using the Reset button located near the NPort 5200’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 5200 by using the Windows Administrator Import function.

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 5200 uses cookies only for “password” transmission.

Basic Settings

Time

NPort 5200 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.

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 5200’s firmware will

modify the GMT time according to the Time Zone.

Input the correct “Time server” IP address or domain name. Once NPort 5200 is configured

with the correct Time server address, NPort 5200 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 5200. The factory default for both Web

console and Telnet console is Enable.

Setting Factory Default Necessity

Network Settings

General Setting

Click “General Setting” option ,you can entry the server name and DNS server .

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 5200’s DNS feature, you need to configure the DNS server. Doing so allows

NPort 5200 to use a host’s domain name to access the host. NPort 5200 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.

Ethernet Configuration

You must assign a valid IP address to NPort 5200 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 5200 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.

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

(IP addresses of the form x.x.x.0

and x.x.x.255 are invalid.)

192.168.126.254 Required

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 5200 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 5200, a

connection is established directly from the NPort 5200. 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 5200 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

DHCP

DHCP/BOOTP

BOOTP

Static Required

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

(192.168.126.254), Netmask, and Gateway for IP settings.

WLAN Configuration

WLAN Configuration -> WLAN

The NPort supports IEEE 802.11b wireless network interface.

The supported IP configurations are static and dynamic (BOOTP , DHCP or BOOTP+DHCP ),

depending on users’ network environment. Users can setup the IP configuration via the serial

console, or the Web/Telnet consoles through Ethernet interface.

WLAN Mode :

<Ad-Hoc Mode>

In the above example, two NPort device have established an Ad-Hoc peer-to-peer

relationship. They communicate directly to each other’s serial devices without AP.

In the above example, the NPort device communicates with host computer via the

AP. The host computer is connected via an Ethernet connection to the AP. As such, the NPort

device and the host computer communicate directly and can transfer information to serial devices.

SSID:

Enter the name of the wireless network (SSID). The W2250/2150 connects to this wireless

network.

Channel:

Select from the pull down menu the radio channel for wireless network. In infrastructure mode, AP

will specify channel automatically. In Ad-hoc mode, user can specify channel by self.

If you want to change the WLAN IP address quickly, you can click the Wizard to configure.

WLAN Configuration -> Security

The wireless network interface supports data encryption (WEP, 64 or 128 bits) and authentication

(Open or Shared authentication).

Autherntication: Select an authentication scheme from the pull down menu: Open or Shared. Selecting

Shared requires manually entering the authentication key.

WEP Mode: enable WEP ,data packet will be encrypted before send .you can select 64 bit or 128

bit .By default, WEP Mode is disabled.

WEP Key format: There are two formats for selection, ASCII or HEX。

WEP Key1~ WEP Key4：There are four WEP Key to prevent data from steal.The setting of WEP

Key must be the same as AP.

Serial Port Settings

Serial Port Settings -> Operation Mode

Real COM Mode

TCP alive check time

Setting Factory Default Necessity

0 to 99 min 7 min Optional

0 min: TCP connection is not closed due to an idle TCP connection.

1 to 99 min: NPort 5200 automatically closes the TCP connection if there is no TCP activity

for the given time. After the connection is closed, NPort 5200 starts listening for another

Real COM driver connection from another host.

Max connection

Setting Factory Default Necessity

1, 2, 3, 4 1 Required

Max connection is usually used when the user needs to receive data from different hosts

simultaneously. The factory default is 1. In this case, only one specific host can access this

port of the NPort 5200, and the Real COM driver on that host will have full control over the

port.

Max. connection 1:

Allows only 1 host’s Real COM driver to open the specific NPort 5200 serial port.

Max connection 2 to 4:

Allows 2 to 4 host’s Real COM drivers to open the specific NPort 5200 serial port, at the

same time. When multiple hosts’ Real COM drivers open the serial port at the same time, the

COM driver only provides a pure data tunnel without control ability.

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 the data back to the driver on the host.

Data will be sent first-in-first-out when data comes into the NPort 5200 from the Ethernet

interface.

When Max connection is set to 2, 3, or 4, this means that NPort 5200 will be using a “multi

connection application” (i.e., 2, 3, or 4 hosts are allowed access to the port at the same time).

When using a multi connection application, NPort 5200 will use the serial communication

parameters set in the console. All of the hosts connected to that port must use the same serial

settings. If one of the hosts opens the COM port with parameters that are different from NPort

5200’s console setting, data communication may not work properly.

Delimiter 1

Setting Factory Default Necessity

00 to FF (hex) None Optional

Delimiter 2

Setting Factory Default Necessity

00 to FF (hex) None Optional

Once the NPort 5200 receives both delimiters through its serial port, it immediately packs all

data currently in its buffer and sends it to the NPort 5200’s Ethernet port.

Delimiter 2 is optional. If left blank, then Delimiter 1 alone trips clearing of the buffer. If the size

of the serial data received is greater than 1 KB, the NPort 5200 will automatically pack the data

and send it to the Ethernet. However, to use the delimiter function, you must at least enable

Delimiter 1. If Delimiter 1 is left blank and Delimiter 2 is enabled, the delimiter function will not

work properly.

Force transmit

Setting Factory Default Necessity

0 to 65535 ms 0 ms Optional

0: Disable the force transmit timeout.

1 to 65535: Forces the NPort 5200’s TCP/IP protocol software to try to pack serial data

received during the specified time into the same data frame.

This parameter defines the time interval during which NPort 5200 fetches the serial data from

its internal buffer. If data is incoming through the serial port, NPort 5200 stores the data in

the internal buffer. NPort 5200 transmits data stored in the buffer via TCP/IP, but only if the

internal buffer is full or if the Force transmit time interval reaches the time specified under

Force transmit timeout.

The optimal Force transmit timeout depends on your application, but it must be at least larger

than one character interval within the specified baud rate. For example, 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 Force transmit timeout to be larger than 8.3 ms, so in this case, it

must be greater than or equal to 10 ms.

If the user wants to send a series of characters in the same packet, the serial device attached

to NPort 5200 should send that series of characters during a time interval less than the Force

transmit timeout for NPort 5200, and the total length of data must be less than or equal to

NPort 5200’s internal buffer size. The serial communication buffer size for NPort 5200 is 1

KB per port.

TCP Server Mode

TCP alive check time

Setting Factory Default Necessity

0 to 99 min 7 min Optional

0 min: TCP connection is not closed due to an idle TCP connection.

1 to 99 min: NPort 5200 automatically closes the TCP connection if there is no TCP activity

for the given time. After the connection is closed, NPort 5200 starts listening for another

host’s TCP connection.

Inactivity time

Setting Factory Default Necessity

0 to 65535 ms 0 ms Optional

0 ms: TCP connection is not closed due to an idle serial line.

0-65535 ms: NPort 5200 automatically closes the TCP connection if there is no serial data

activity for the given time. After the connection is closed, NPort 5200 starts listening for

another host’s TCP connection.

This parameter defines the maintenance status as Closed or Listen for the TCP connection.

The connection is closed if there is no incoming or outgoing data through the serial port

during the specific Inactivity time.

If the Inactivity time is set to 0, the current TCP connection is kept active until a connection

close request is received. Although Inactivity time is disabled, the NPort 5200 will check the

connection status between the NPort 5200 and remote host by sending “keep alive” packets

periodically. If the remote host does not respond to the packet, NPort 5200 assumes that the

connection was closed down unintentionally. NPort 5200 will then force the existing TCP

connection to close.

The Inactivity time should at least be set larger than that of Force transmit timeout. To prevent

the unintended loss of data due to the session being disconnected, it is highly recommended that

this value is set large enough so that the intended data transfer is completed.

Max connection

Setting Factory Default Necessity

1, 2, 3, 4 1 Required

Max connection is usually used when the user needs to receive data from different hosts

simultaneously. The factory default only allows 1 connection at a time.

Max. Connection 1:

NPort 5200 only allows 1 host to open the TCP connection to the specific serial port.

Max Connection 2 to 4:

Allows 2 to 4 host’s TCP connection request to open this NPort 5200 serial port, at the same

time. When multiple hosts establish a TCP connection to the specific serial port at the same

time, NPort 5200 will duplicate the serial data and transmit to all of the hosts. Ethernet data

is sent on a first-in-first-out basis to the serial port when data comes into NPort 5200 from

the Ethernet interface.

Delimiter 1

Setting Factory Default Necessity

00 to FF None Optional

Delimiter 2

Setting Factory Default Necessity

00 to FF None Optional

Once the NPort 5200 receives both delimiters through its serial port, it immediately packs all

data currently in its buffer and sends it out the NPort 5200’s Ethernet port.

Delimiter 2 is optional. If left blank, then Delimiter 1 alone trips clearing of the buffer. If the size

of the serial data received is greater than 1 KB, the NPort 5200 will automatically pack the data

and send it to the Ethernet. However, to use the delimiter function, you must at least enable

Delimiter 1. If Delimiter 1 is left blank and Delimiter 2 is enabled, the delimiter function will not

work properly.

Force transmit

Setting Factory Default Necessity

0 to 65535 ms 0 ms Optional

0: Disable the force transmit timeout.

1 to 65535: Forces the NPort 5200’s TCP/IP protocol software to try to pack serial data

received during the specified time into the same data frame.

This parameter defines the time interval during which NPort 5200 fetches the serial data from

its internal buffer. If data is incoming through the serial port, NPort 5200 stores the data in

the internal buffer. NPort 5200 transmits data stored in the buffer via TCP/IP, but only if the

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 Force transmit timeout to be larger than 8.3 ms, so in this case, it

must be greater than or equal to 10 ms.

If the user wants to send a series of characters in the same packet, the serial device attached

to NPort 5200 should send that series of characters during a time interval less than the Force

transmit timeout for NPort 5200, and the total length of data must be less than or equal to

NPort 5200’s internal buffer size. The serial communication buffer size for NPort 5200 is 1

KB per port.

Local TCP port

Setting Factory Default Necessity

1 to 65535 4001 Required

The”Local TCP port” is the TCP port that NPort 5200 uses to listen to connections, and that

other devices must use to contact NPort 5200. To avoid conflicts with well known TCP ports,

the default is set to 4001.

Command port

Setting Factory Default Necessity

1 to 65535 966 Optional

The “Command port” is a listen TCP port for IP-Serial Lib commands from the host. In order

to prevent a TCP port conflict with other applications, the user can set the Command port to

another port if needed. IP-Serial Lib will automatically check the Command Port on NPort

5200 so that the user does not need to configure the program.

TCP Client Mode

TCP alive check time

Setting Factory Default Necessity

0 to 99 min 7 min Optional

0 min: TCP connection is not closed due to an idle TCP connection.

1 to 99 min: NPort 5200 automatically closes the TCP connection if there is no TCP activity

for the given time.

Inactivity time

Setting Factory Default Necessity

0 to 65535 ms 0 ms Optional

0 ms: TCP connection is not closed due to an idle serial line.

0-65535 ms: NPort 5200 automatically closes the TCP connection if there is no serial data

activity for the given time.

This parameter defines the maintenance status as Closed or Listen for the TCP connection.

The connection is closed if there is no incoming or outgoing data through the serial port

during the specific Inactivity time.

If the Inactivity time is set to 0, the current TCP connection is kept active until a connection

close request is received. Although Inactivity time is disabled, the NPort 5200 will check the

connection status between the NPort 5200 and remote host by sending “keep alive” packets

periodically. If the remote host does not respond to the packet, NPort 5200 assumes that the

connection was closed down unintentionally. NPort 5200 will then force the existing TCP

connection to close.

The Inactivity time should at least be set larger than that of Force transmit timeout. To prevent

the unintended loss of data due to the session being disconnected, it is highly recommended that

this value is set large enough so that the intended data transfer is completed.

Inactivity time is ONLY active when “TCP connect on” is set to “Any character.”

Delimiter 1

System Management

System Management -> Accessible IP Settings

NPort 5200 uses an IP address based filtering method to control access to itself.

Accessible IP Settings allows you to add or block remote host IP addresses to prevent

unauthorized access. Access to NPort 5200 is controlled by IP address. That is, if a

host’s IP address is in the accessible IP table, then the host will be allowed to access

the NPort 5200. You can allow one of the following cases by setting the parameter.

 Only one host with a specific IP address can access the NPort 5200

Enter “IP address/255.255.255.255” (e.g.,

“192.168.1.1/255.255.255.255”).

 Hosts on a specific subnet can access the NPort 5200

Enter “IP address/255.255.255.0” (e.g., “192.168.1.0/255.255.255.0”).

 Any host can access the NPort 5200

Disable this function by un-checking the “Enable the accessible IP list”

checkbox. Refer to the following table for more configuration

System Management -> Auto Warning Settings -> Event Type

Cold start

This refers to starting the system from power off (contrast this with warm start). When

performing a cold start, NPort W2250/W2150 will automatically issue an Auto

warning message by e-mail, or send an SNMP trap after booting up.

Warm start

This refers to restarting the computer without turning the power off. When performing

a warm start, NPort W2250/W2150 will automatically send an e-mail, or send an

SNMP trap after rebooting.

Authentication failure

The user inputs a wrong password from the Console or Administrator. When

authentication failure occurs, NPort W2250/W2150 will immediately send an e-mail

or send an SNMP trap.

IP address changed

The user has changed NPort W2250/W2150’s IP address. When the IP address

changes, NPort W2250/W2150 will send an e-mail with the new IP address before

NPort W2250/W2150 reboots. If the NPort W2250/W2150 is unable to send an e-mail

message to the mail server within 15 seconds, NPort W2250/W2150 will reboot

anyway, and abort the e-mail auto warning.

Password changed

The user has changed NPort W2250/W2150’s password. When the password changes,

NPort W2250/W2150 will send an e-mail with the password changed notice before

NPort W2250/W2150 reboots. If the NPort W2250/W2150 is unable to send an e-mail

message to the mail server within 15 seconds, NPort W2250/W2150 will reboot

anyway, and abort the e-mail auto warning.

DCD changed

The DCD (Data Carrier Detect) signal has changed, also indicating that the modem

connection status has changed. For example, a DCD change to high also means

“Connected” between local modem and remote modem. If the DCD signal changes to

low, it also means that the connection line is down.

When the DCD changes, NPort W2250/2150 will immediately send an e-mail or send

an SNMP trap.

DSR changed

The DSR (Data Set Ready) signal has changed, also indicating that the data

communication equipment’s power is off. For example, a DSR change to high also

means that the DCE is powered ON. If the DSR signal changes to low, it also means

that the DCE is powered off.

When the DSR changes, NPort W2250/2150 will immediately send an e-mail or send

an SNMP trap.

Configuration COM Mapping

NPort COM Driver comes with Windows 98/ME/2000/XP/2003 Real

COM drivers. After you install NPort COM Driver, then you can set up

the NPort W2250/W2150’s serial port as your host’s remote COM port.

Use the following step to map COM ports:

1. Open the COM Mapping utility.

2.click “add” icon

click “Rescan” for search NPort device .

3. you can also select “input manually” . Add the target to which you would

like to map COM ports.

4. Click “yes” to active the COM port, or you can select “apply”

to active the COM port later. Active the COM port to save the

information in the host system registry. The host computer will

not have the ability to use the COM port until after Apply

Change is selected.

5. The word will be turned blue into black

6. Select “COM Setting” to

modify COM No., default

setting, etc.

7. Select the COM No.

COM ports that are “In use” or

“Assigned” will also be indicated

in this drop-down list.

If you select multiple serial ports

or multiple NPort

W2250/W2150s, remember to

check the “Auto Enumerating”

function to use the COM No.

8. Advanced Setting

Tx Mode

Hi-performance mode is the default for Tx mode. If the driver

completes sending data out to the NPort W2250/W2150, the driver

will respond “Tx Empty” to the program.

Under classical mode, the driver will not notify the user’s program

that Tx is completed until all Tx data has been sent out from the

NPort W2250/W2150; this mode will cause lower throughput. If

you want to ensure that all data is sent out before further

processing, classical mode is recommended.

Enable/Disable Tx/Rx FIFO.

If disabled, NPort W2250/W2150 will send one byte each time

the Tx FIFO becomes empty; and an Rx interrupt will be generated

for each incoming byte. This will result in a faster response and

lower throughput. If you want to use XON/XOFF flow control, we

recommend setting FIFO to Disable.

Fast Flush (only flush local buffer)

1. We have added one optional Fast Flush function to Moxa new

NPort Real COM driver.

2. For some applications, the user’s program will use the Win32

“PurgeComm()” function before it reads or writes data. With our

design, after the program uses this Purge Comm() function, the

NPort driver will keep querying NPort’s firmware several times to

make sure there is really no data queued in the NPort firmware

buffer, rather than just flushing the local buffer. This kind of

design is used because of some special considerations. However, it

might take more time (about several hundred milliseconds) than a

native COM1, because it needs to work via Ethernet. That’s why

the native COM ports on the motherboard can work fast with this

function call, but NPort requires much more time. In order to

accommodate other applications that require a faster response

time, the new NPort driver implements a new “Fast Flush” option.

Note that by default, this function is disabled.

3. To begin with, make sure there are some “PurgeComm()”

functions being used in your application program. In this kind of

situation, you might find that your NPort exhibits a much poorer

operation performance than when using the native COM1 port.

Once you have enabled the “Fast Flush” function, you can check to

see if there has been an improvement in performance.

4. By default, the optional “Fast Flush” function is disabled. If you

would like to enable this function, double click on the COM ports

that are mapped to the NPort, and then select the “Fast Flush”

checkbox. You should find that when “Fast Flush” is enabled, the

NPort driver will work faster with “PurgeComm().”

9. The Serial Parameter settings shown here are the default

settings when the NPort W2250/W2150 is powered on.

However, the program can redefine the serial parameters to

different values after the program opens the port via Win 32

API.

10. To save the configuration to a text file, select Export COM

Mapping. You will then be able to import this configuration file to

another host and use the same COM Mapping settings in the other host.

Configuration NPort Search Utility

The Broadcast Search function is used to locate all NPort

W2250/W2150s that are connected to the same LAN as

your computer. After locate NPort W2250/W2150s, you

can also change the IP address.

Since the Broadcast Search function searches by MAC

address and not IP address, all NPort W2250/W2150s

connected to the LAN will be located, regardless of

whether or not they are part of the same subnet as the host.

1. Open NPort Search Utility ,click” search”

2. When the search is complete, the Broadcast Search window

closes, and the NPort W2250/W2150s that were located are

displayed in the window.

3. You can click “assign IP” to change the IP if you need.

Installation for Real TTY and Fixed TTY

1. Procedure

To map NPort serial port to host tty port, you need to:

(1). Setup NPort.

Make sure the IP configuration is ok and you can access

the NPort (ping, telnet...) seccussfully. Then you MUST

configure the NPort serial port to "Real COM Mode".

(2). Install driver files into the host.

Refer to "3.Driver Files Installation"

(3). Map NPort serial to host tty port.

Refer to "4.Mapping TTY Ports"

2. Hardware Installation

Prior to proceed to software installation, please make sure the

hardware installation is completed as user's manual illustrated.

The default IP address for NPort Server is 192.168.127.254.

!!!!!!!!!!!!!!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!

After hardware installation, you MUST configure the NPort

operating mode to "Real COM Mode".

!!!!!!!!!!!!!!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!

3. Driver Files Installation

a. Get the driver file from product CD-ROM or web site.

b. Login into the console as a super user (root).

c. Execute 'cd /' to go to root directory.

d. Copy the driver file npreal2xx.tgz into '/' directory.

e. Execute 'tar xvfz npreal2xx.tgz' to copy all files into the system.

f. Execute '/tmp/moxa/mxinst'.

!!!!!!!!!!!!!!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!

For RedHat AS/ES/WS and Fedora Core1, extra

argument is needed:

# /tmp/moxa/mxinst SP1

!!!!!!!!!!!!!!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!

g. The shell script will install the driver files automatically.

After installing driver successfully, you can see the

several files in /usr/lib/npreal2/driver, inlcuding

- mxaddsvr (Add Server, mapping tty port)

- mxdelsvr (Delete Server, un-mapping tty port)

- mxloadsvr (Reload Server)

- mxmknod (Create device node/tty port)

- mxrmnod (Remove device node/tty port)

- mxuninst (Remove tty port and driver files)

Now you are ready to map NPort serial port into system tty port.

Please see "4.Mapping TTY Ports".

4. Mapping TTY Ports

Before mapping tty ports, you have to set the operation mode of

your NPort Product to "Real Com Mode". We provide two ways to map

tty ports.

Mapping tty ports automatically

After logging in as a super user, you can enter the directory

"/usr/lib/npreal2/driver" and then execute "mxaddsvr" program

to map the target NPort serial port to host tty ports.

The syntax of mxaddsvr is:

"mxaddsvr [NPort IP Address] [Total Ports] ([Data port] [Cmd port])"

For example1:

# cd /usr/lib/npreal2/driver

# ./mxaddsvr 192.168.3.4 16

For example2:

# cd /usr/lib/npreal2/driver

# ./mxaddsvr 192.168.3.4 16 4001 966

In example1, 16 tty ports will be added with ip "192.168.3.4" and

data port(950, 951, ...965), command port(966, 967, 968.., 981).

In example2, 16 tty ports will be added with ip "192.168.3.4" and

data port(4001, 4002, ..4016), command port(966, 967, 968.., 981).

The following actions will be performed.

- Modify the "npreal2d.cf"

- Create tty ports in directory "/dev" with major & minor number

configured in "npreal2d.cf".

- Stop and then restart the driver.

5. Remove Mapped TTY ports

Similar to "Mapping TTY Ports", we provide two ways:

Remove the mapped tty ports automatically

After logging in as root, you can enter the directory

"/usr/lib/npreal2/driver" and then execute "mxdelsvr"

program to delete a server. The syntax of mxdelsvr is

"mxdelsvr [IP]", For example:

# cd /usr/lib/npreal2/driver

# ./mxdelsvr 192.168.3.4

If you don't provide the IP address in the command line, the

program will list the installed servers and total ports on screen.

So you can only choose the index on the installed server list to delete.

The following actions will be performed.

- Modify the "npreal2d.cf"

- Remove the relevant tty ports in directory "/dev"

- Stop and then restart the driver.

6. Driver Files Removal

Drvier Removal will remove all driver files, mapped tty ports and

unload the driver. To do this, you only need to enter the directory

"/usr/lib/npreal2/driver", and then execute "mxuninst" to uninstall

the driver. This program will perform the following actions.

- Unload the driver.

- Delete all files and directories in "/usr/lib/npreal2"

- Delete directory "/usr/lib/npreal2".

- Modify the system initializing script file.

1. Installation and Configuration

step 1 : login to UNIX and create a directory for MOXA TTY,

for instance, /usr/etc.

# mkdir /usr/etc

# cd /usr/etc

step 2 : Extract source code from tar-file :

Type "tar xvf moxattyd.tar".

After extract, you can find the following files :

README --> this file

moxattyd.c --> source program

moxattyd.cf --> empty configuration file

Makefile --> makefile

step 3 : Compile and Link :

For SCO UNIX:

# make sco

For Linux:

# make linux

For UnixWare 7:

# make svr5

For UnixWare 2.1.x, SVR4.2:

# make svr42

For IBM AIX:

# make aix

For HP-UNIX:

# make hpunix

For SunOS 5.8:

# make sun

For QNX6:

# make qnx6

step 4 : Modify configuration :

The configuration of moxattyd program is defined on

"moxattyd.cf" file at the same directory where contains

program moxattyd.

User can use vi or any edit to modify it. It's a text

file.

For more configuration information, please take a look

at moxattyd.cf file. We put detail decription on it.

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Please note that the "Device Name" is depended on OS.

See "E. Device Naming Rule" for more information.

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

step 5 : Add program moxattyd into /etc/inittab and any tty name

you configued at moxattyd.cf.

eg. for Linux:

ts:2:respawn:/usr/etc/moxattyd

p1:345:respawn:/etc/mingetty ttyp1

p2:345:respawn:/etc/mingetty ttyp2

finish : You have finished the installation and configuration

of MOXA TTY.

2. Start moxattyd program

Run "init q" or reboot your UNIX.

3. Add additional server

Step 1: Modify "moxattyd.cf" file to add additional server.

User can use vi or any edit to modify it. It's a text

file.

For more configuration information, please take a look

at moxattyd.cf file. We put detail decription on it.

Step 2: Find the proccess id (PID) of program "moxattyd".

# ps -ef | grep moxattyd

Step 3: Update configuration of moxattyd program.

# kill -USR1 PID

(ex. if "moxattyd" PID = 404, "kill -USR1 404")

finish : You have finished to add additional server.

Upgrade Firmware

Well Known Port Numbers

---------------------------------------------------------------------------------------------------

In this appendix, which is included for your reference, we provide a list of Well

Known port numbers that may cause network problems if you set NPort 5200 to one

of these ports. Refer to RFC 1700 for Well Known port numbers, or refer to the

following introduction from the IANA.

The port numbers are divided into three ranges: the Well Known Ports, the Registered

Ports, and the Dynamic and/or Private Ports.

The Well Known Ports range from 0 through 1023.

The Registered Ports range from 1024 through 49151.

The Dynamic and/or Private Ports range from 49152 through 65535.

The Well Known Ports are assigned by the IANA, and on most systems, can only be

used by system processes or by programs executed by privileged users. The following

table shows famous port numbers among the well-known port numbers. For more
