ATTENTION

Safety First!

Be sure to disconnect the power cord before installing and/or wiring your NPort IA5150A/IA5250A

Wiring

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 the NPort IA5150A/IA5250A. When plugged in, the NPort IA5150A/IA5250A’s

internal components generate heat, and consequently the casing may feel hot to the touch. When

alled

with other components, make sure that there is at least 2 cm clearance on all sides of

IA5150A/IA5250A in order to allow proper heat dissipation.

Connecting the Hardware

This section describes how to connect the NPort IA5150A/IA5250A to serial devices for first time testing

purposes. We cover Wiring Requirements, Connecting the Power, Grounding the NPort

IA5150A/IA5250A Series, Connecting to the Network, Connecting to a Serial Device, and LED

Indicators.

Wiring Requirements

You should heed the following:

• 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 the NPort IA5150A/IA5250A’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 the NPort IA5150A/IA5250A Series

Grounding and wire routing helps limit the effects of noise caused by electromagnetic interference (EMI). Run

the ground connection from the ground screw to the grounding surface prior to connecting devices.

Connecting to the Network

Connect one end of the Ethernet cable to the NPort IA5150A/IA5250A’s 10/100M Ethernet port and the other

end of the cable to the Ethernet network. If the cable is properly connected, the NPort IA5150A/IA5250A 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 the NPort IA5150A/IA5250A and the serial device. Serial data cables are

optional accessories for NPort.

LED Indicators

The top panels of all NPort IA5150A/IA5250As have four LED indicators, as described in the following table.

LED Name LED Color LED Function

Ready red Steady on: Power is on and the NPort IA5150A/IA5250A is booting up.

Blinking: Indicates an IP conflict, or DHCP or BOOTP server did not

respond properly, or a relay output occurred.

When the above two conditions occur at the same time,

check the relay output first. If after resolving the relay output

the Ready LED is still blinking, then there is an IP conflict, or

the DHCP or BOOTP server did not respond properly.

Adjust the Pull-high/Pull-low Resistors and Terminators for

RS-422/RS-485 Ports

In certain critical environments, you may need to add termination resistors to prevent the reflection of serial

signals. When using termination resistors, it is important to set the pull high/low resistors properly so that

electrical signals do not become corrupted. It is improbable for a single pull high/low resistor value to suit all

the various environments and this is why the NPort IA5150A/IA5250A series provides DIP switches for setting

the pull high/low resistor values for each serial port.

The DIP switches are located on the PCB board; you will need to take off the covers to access them. To set the

pull-high resistor to 150 KΩ, flip DIP1 to “OFF,” and then set the pull-low resistor to 150 KΩ, and then flip DIP2

to “OFF.” To set the pull-high resistor to 1 KΩ, flip DIP1 to “ON,” and then set the pull-low resistor to 1 KΩ, and

then flip DIP2 to “ON.” Make sure that DIP3 is “ON” to enable the 120Ω terminator. The default settings for the

pull-high and pull-low resistors, and the terminators are all at “OFF.”

3. Initial IP Address Configuration

When setting up your NPort IA5150A/IA5250A 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 the NPort

IA5150A/IA5250A’s IP Address. For more details about network settings, see the Network Settings

Initializing the NPort’s IP Address

Determine whether your NPort IA5150A/IA5250A needs to use a Static IP or Dynamic IP (either DHCP or

BOOTP application).

If the NPort IA5150A/IA5250A is used in a Static IP environment, you can use the NPort

Administration Suite, ARP, Web Console, Telnet Console, or Serial Console to configure the new IP address.

If the NPort IA5150A/IA5250A is used in a Dynamic IP environment, you can use the NPort

Administration Suite, Web Console, Telnet Console, or Serial Console to configure the NPort IA5150A/IA5250A

to get an IP address dynamically with DHCP, DHCP/BOOTP, or BOOTP.

Factory Default IP Address

NPort IA5150A/IA5250A 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 IA5150A/IA5250A 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 Administration Suite

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

NPort IA5150A/IA5250A.

See Chapter 5 for details on how to install NPort Administration Suite, and how to use this suite of

useful utilities to set up IP addresses and configure your NPort IA5150A/IA5250A 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

IA5150A/IA5250A. The ARP command tells your computer to associate the NPort IA5150A/IA5250A’s MAC

address with the intended IP address. You must then use Telnet to access the NPort IA5150A/IA5250A, at

which point the device server’s IP address will be reconfigured.

ATTENTION

Figures in this chapter were generated using NPort

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

1. Obtain a valid IP address for your NPort IA5150A/IA5250A from your network administrator.

2. Obtain the NPort IA5150A/IA5250A’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:

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

5. 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 IA5150A/IA5250A. (Be sure to use the actual IP address and MAC address for your NPort

IA5150A/IA5250A.)

6. 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 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 IA5150A/IA5250A’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

4. Choosing the Proper Operation Mode

In this chapter, we describe the NPort IA5150A/IA5250A various Toperation 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

NPort IA5150A/IA5250A 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 the NPort IA5150A/IA5250A 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.

The NPort IA5150A/IA5250A 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, the NPort IA5150A/IA5250A 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.

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 IA5150A/IA5250A 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 IA5150A/IA5250A’s serial ports.

Real COM Mode comes with the NPort IA5150A/IA5250A NPort Administrator.

RFC2217 Mode

RFC2217 mode is similar to Real COM mode in that a driver is used to establish a transparent connection

between a host computer and a serial device by mapping the serial port on the NPort IA5150A/IA5250A to a

local COM port on the host computer. RFC2217 defines general COM port control options based on the Telnet

protocol. Third party drivers supporting RFC2217 are widely available on the Internet and can be used to

Pair Connection Mode

Pair Connection Mode employs two NPort IA5150A/IA5250A units in tandem, and can be used to remove the

15-meter distance limitation imposed by the RS-232 interface. One NPort IA5150A/IA5250A is connected from

its RS-232 port to the COM port of a PC or other type of computer, such as a hand-held PDA, and the serial

device is connected to the RS-232 port of the other NPort IA5150A/IA5250A. The two NPort IA5150A/IA5250A

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 NPort device servers.

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 the NPort IA5150A/IA5250A’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

NPort IA5150A/IA5250A Series Choosing the Proper Operation Mode

4-5

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 Reverse Telnet mode.

Disabled Mode

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

Network Settings

You mu st assign a valid IP address to the NPort IA5150A/IA5250A before the NPort can start operating within

your network. 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 the NPort IA5150A/IA5250A

will not have a valid connection to the network). First time users may refer to Chapter 3, Initial IP Address

A subnet mask represents all the network hosts at one geographic location, such as all the hosts in a building

or on the same local area network. When a packet is sent out over the network, the NPort IA5150A/IA5250A

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 IA5150A/IA5250A, a connection

is established directly from the NPort IA5150A/IA5250A. Otherwise, the connection will be established through

the given default gateway.

In order to use the NPort IA5150A/IA5250A’s DNS feature, you need to configure the DNS server. Doing so

allows the NPort IA5150A/IA5250A to use a host’s domain name to access the host. The NPort

IA5150A/IA5250A 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.

The NPort IA5150A/IA5250A acts as a DNS client by actively querying the DNS server for the IP address that

is associated with a particular domain name. NPort IA5150A/IA5250A functions that support domain name are

with IP management tasks. For example, if the NPort IA5150A/IA5250A 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 the NPort IA5150A/IA5250A, the host needs a way to determine the NPort IA5150A/IA5250A’s new

IP address.

NPort IA5150A/IA5250A products help out by periodically reporting their IP addresses 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 the NPort IA5150A/IA5250A’s

Auto IP report.

1. Use the NPort Administrator’s IP Address Report function.

2. Use “Auto IP report protocol”, which can automatically receive the Auto IP report on a regular basis. It can

also be used to help you develop your own software. Refer to Appendix E for the “Auto IP report protocol”.

ATTENTION

When "Max connection" is set greater than 1, this means that

“multi connection application” (i.e., up to eight hosts are allowed access to the port at the same time). When

using a

parameters set in

one

of the

console setting, data communication may not transmit properly.

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

factory default is 1, this means that only one specific host can access this NPort IA5150A/IA5250A, and the

Real COM driver on that host will have full control over the port.

Max Connection 1:

Only a single host’s Real COM driver can access the specific NPort IA5150A/IA5250A serial port.

Max Connection 2 to 8:

Allows two to eight host’s Real COM drivers to access the specific NPort IA5150A/IA5250A serial port at the

same time. When multiple hosts’ Real COM drivers access the serial port at the same time, the COM driver only

provides pure data tunneling without control ability. This means that the serial port will use the parameter of

the firmware’s settings and not those of your application program (AP).

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

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

host.

Data will be sent first-in-first-out when the data is received by the NPort IA5150A/IA5250A from the Ethernet

No or Yes No Optional

If you select “No” when Max connections is > 1 and the serial device is transmitting data, in the event one of

the connected hosts is not responding, the second group of data will not be sent until all the data from the first

group has been successfully transmitted. If you select “Yes” for “Ignore jammed IP,” hosts that are not

responding will be ignored, but the data will still be transmitted to all the other hosts.

Allow driver control

Setting Factory Default Necessity

No or Yes No Optional

If “Max connection” is greater than 1, NPort will ignore the driver control commands from all connected hosts.

However, if you set “Allow driver control” to “Yes,” control commands will be accepted. Note: Since the NPort

IA5150A/IA5250A may get configuration changes from multiple hosts, the most recent command it receives

will take precedence.

Packing length

length (in bytes) matches the configured value, the data will be forced out. The data length can be configured

for 0 to 1024 bytes. Set to 0 if you do not need to limit the length.

1 to 65535: Forces the NPort IA5150A/IA5250A’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 the NPort IA5150A/IA5250A fetches the serial data from

its internal buffer. If data is incoming through the serial port, the NPort IA5150A/IA5250A stores the data in its

internal buffer. The NPort IA5150A/IA5250A transmits the 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 the Force transmit

timeout.

The ideal Force transmit timeout depends on your application, but it must be at least larger than a single

character interval within the specified baudrate. 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 the 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 a user wants to send a series of characters in the same packet, the serial device attached to the NPort

IA5150A/IA5250A should send that series of characters during a time interval that is less than the Force

transmit timeout of the NPort IA5150A/IA5250A, and the total length of data must be less than or equal to the

NPort IA5150A/IA5250A’s internal buffer size. The serial communication buffer size for the NPort

0: Disable the force transmit timeout.

1 to 65535: Forces the NPort IA5450A’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 the NPort IA5450A fetches the serial data from its

internal buffer. If data is incoming through the serial port, the NPort IA5450A stores the data in the internal

buffer. The NPort IA5450A 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 baudrate. 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 a value 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 the NPort

IA5450A should send that series of characters during a time interval less than the Force transmit timeout for

the NPort IA5450A, and the total length of data must be less than or equal to the NPort IA5450A’s internal

buffer size. The serial communication buffer size for the NPort IA5450A is 1 KB per port.

UDP Multicast

A multicast is a packet sent by one host to multiple hosts. In multicast, each host that belongs to a specific

multicast group will receive multicast packets for that group. To configure a host as a multicast receiver over

the Internet, it must inform the routers on its LAN. The Internet Group Management Protocol (IGMP) is used to

communicate group membership information between hosts and routers on a LAN. NPort IA5150A/IA5250A

supports IGMP version 2.

You could key in the IP (ex. 239.1.1.1) that multicast group assigned into the column of Destination IP address,

and next, NPort would automatically add the Group, receiving all packets from this group in order to fulfill the

function of multicast.

Dial-in

The NPort IA5150A/IA5250A listens for a TCP/IP connection request from the remote Ethernet modem or host.

NPort IA5150A/IA5250A’s response depends on the ATS0 value, as outlined below.

ATS0=0 (default):

The NPort IA5150A/IA5250A will temporarily accept the TCP connection and then send the “RING” signal out

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

request, after which NPort IA5150A/IA5250A enters data mode. If no “ATA” command is received, NPort

IA5150A/IA5250A will disconnect after sending three “RING” signals.

≧

ATS0

The NPort IA5150A/IA5250A will accept the TCP connection immediately and then send the “CONNECT <baud>”

command to the serial port, in which <baud> represents the baudrate of the NPort IA5150A/IA5250A’s serial

port. After that, the NPort IA5150A/IA5250A immediately enters data mode.

Dial-out

The NPort IA5150A/IA5250A accepts the AT command “ATD <IP>:<TCP port>” from the serial port and then

requests a TCP connection from the remote Ethernet Modem or PC. This is where <IP> is the IP address of the

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

Once the remote unit accepts this TCP connection, the NPort IA5150A/IA5250A will send out the “CONNECT

<baud>” signal via the serial port and then enter data mode.

Disconnection request from local site

When the NPort IA5150A/IA5250A is in data mode, the user can drive the DTR signal to OFF, or send “+++”

from the local serial port to the NPort IA5150A/IA5250A. The NPort IA5150A/IA5250A will enter command

mode and return “NO CARRIER” via the serial port, and then input “ATH” to shut down the TCP connection after

1 second.

After the TCP connection has been shut down by the remote Ethernet modem or PC, the NPort

IA5150A/IA5250A will send the “NO CARRIER” signal via the serial port and then return to command mode.

AT Commands

The NPort IA5150A/IA5250A supports the following common AT commands used with a typical modem:

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

Access to the NPort IA5150A/IA5250A 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 the NPort IA5150A/IA5250A. You can allow one

of the following cases by setting the parameter.

Only one host with a specific IP address can access the NPort IA5150A/IA5250A

seconds, the NPort IA5150A/IA5250A will reboot anyway, and abort the e-mail auto warning.

Power failure

We provide two DC power inputs for redundancy. The NPort IA5150A/IA5250A Series supports different

approaches to warn engineers automatically, such as by email or relay output. Users can connect to “Monitor

-> Relay Output” from the web console to check what event causes the warning. The relay output will be

canceled after the power recovers, or by selecting “acknowledge event” using the web console or Telnet. When

the Relay Output is sending a warning, the Ready LED will flash red until the warning event ceases.

Ethernet link down

The NPort IA5150A/IA5250A Series provides system maintainers with real-time alarm messages for Ethernet

link down. Even when control engineers are out of the control room for an extended period of time, they can still

be informed of the status of devices almost instantaneously when exceptions occur. The NPort

IA5150A/IA5250A Series supports different methods for warning engineers automatically, such as by email,

SNMP trap, and relay output. Users can connect to “Monitor -> Relay” Output from the web console to check

which Ethernet port is causing the warning. The relay output will be canceled if the failed Ethernet link is

restored, or by selecting Acknowledge Event from the web console or Telnet. When the Relay Output is issuing

a warning, the Ready LED will flash in red until the warning event ceases.

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, the NPort IA5150A/IA5250A will immediately send an e-mail, send an SNMP trap,or

trigger the relay output..

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, the NPort IA5150A/IA5250A will immediately send an e-mail, send an SNMP trap, or

trigger the relay output.

COM Mapping

Windows Administration Suite comes with Windows Real COM drivers. After you install NPort Administration

Suite, there are two ways to set up the NPort IA5150A/IA5250A serial port as your host’s remote COM port.

The first way is with On-line COM Mapping. On-line COM Mapping will check to make sure that the NPort

IA5150A/IA5250A is connected correctly to the network and then install the driver on the host computer.

NPort IA5150A/IA5250A Series Configuring NPort Administrator

6-13

The second way is with Off-line COM Installation, without first connecting the NPort IA5150A/IA5250A to

the network. Off-line COM Mapping can decrease the system integrator’s effort by solving different field

problems. Via off-line installation, users can first process software installation for the host, and then install the

NPort IA5150A/IA5250A to different fields.

Use the following procedure to map COM ports:

1. On-line COM Mapping:

Connect NPort IA5150A/IA5250A to the network  Set NPort IA5150A/IA5250A to the proper IP address 

Map COMs to your host  Apply Change.

2. Off-line COM Mapping:

Map COMs to your host  Apply Change  Connect the NPort IA5150A/IA5250A to the network 

Configure NPort IA5150A/IA5250A’s IP address.

On-line COM Mapping

1. Broadcast Search for NPort IA5150A/IA5250As on the network.

2. Select the COM Mapping function group.

3. Add the target to which you would like to map COM ports.

4. The NPort IA5150A/IA5250A list that appears is the list generated by the previous Broadcast Search. Select

the NPort IA5150A/IA5250A to which you would like to map COM ports.

5. Select COM Settings to modify COM No., default setting, etc.

NPort IA5150A/IA5250A Series Configuring NPort Administrator

6-14

6. Select the COM Number. 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 IA5150A/IA5250As, remember to check the “Auto

Enumerating” function to use the COM No. you select as the first COM No.

Hi-performance mode is the default for Tx mode. If the driver completes sending data out to the NPort

IA5150A/IA5250A, 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 IA5150A/IA5250A; 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, the NPort IA5150A/IA5250A 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)

• 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 the 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 (on the order of 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 the 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.

• 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.

• By default, the optional “Fast Flush” function is disabled. If you would like to enable this function, from

the “NPort Administrator,” double click 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().”

7. The Serial Parameter settings shown here are the default settings when the NPort IA5150A/IA5250A is

powered on. However, the program can redefine the serial parameters to different values after the program

opens the port via API.

8. After setting the COM Mapping, remember to select Apply Change 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.

9. Select Discard Change to tell Administrator NOT to save the COM Mapping information to the host.

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.

Off-line COM Mapping

1. Add a target by inputting the IP address and selecting the Model Name without physically connecting the

NPort IA5150A/IA5250A to the network.

2. Modify the port settings as needed.

3. Right click in the NPort list section and select Apply Change.

Overview

What is IP Serial Library?

IP Serial Library is a Windows library with frequently used serial command sets and subroutines. IP Serial

Library is designed to reduce the complexity and poor efficiency of serial communication over TCP/IP. For

example, Telnet can only transfer data, but it can't monitor or configure the serial line’s parameters.

Why Use IP Serial Library?

For programmers who are familiar with serial communication, IP Serial Library provides well-designed function

calls that have the same style as Moxa’s PComm Library.

IP Serial Library is amazingly simple and easy to understand. By including it in your VB, C, or Delphi

programming environment, you can program your own TCP/IP application with the ability to control serial

communication parameters.

NPort IA5150A/IA5250A serial device servers use 2 TCP ports for communication between the NPort

IA5150A/IA5250A and host computer’s Real COM driver. The NPort IA5150A/IA5250A uses a data port and

command port to provide pure data transfer without decode and encode. Compared to using only one TCP port

to control serial communication (such as RFC2217), IP Serial Library uses a command port to communicate

with the NPort IA5150A/IA5250A in user’s program. IP Serial Library not only runs with excellent efficiency but

also runs without any decode or encode problems.

How to install IP Serial Library?

IP Serial Lib comes with the NPort IA5150A/IA5250A Administration Suite. Refer to the IP Serial directory for

more detail about the function definitions.
