Overview
Welcome to Moxa NPort Server Pro, an Industrial Serial Device Server that greatly enhances the
ability of a Windows NT/95/98 host to control multiple serial port devices over a TCP/IP based
Ethernet network.

NPort Server Pro provides a data communication solution for connecting Windows NT/95/98 hosts
to multiple asynchronous RS-232 serial ports through a TCP/IP network. Each model has 8 (DE-308)
or 16 (DE-303) asynchronous RS-232 serial port connections, and one 10/100 Mbps Ethernet
connection, allowing any device that supports primarily the asynchronous communications protocol
to attach to a network. NPort Server Pro works like an add-on multi-port serial board to the NT/95/98
server, but with one major advantage—the TCP/IP network. Since the Windows NT/95/98 host
communicates with the COM ports on Nport Server Pro over a TCP/IP network, you are able to
control asynchronous serial devices from virtually anywhere in the world.
Although it connects through the virtual link of the Ethernet, the ports on NPort Server Proare
recognized as real COM ports by the Windows NT/95/98 operating system. NPort Server Pro
provides the basic transmit/receive data functions, as well as RTS, CTS, DTR, DSR, and DCD
control signals. Moreover, the NPort Server Pro driver is fully compatible with the Windows
NT/95/98 standard COM driver.
NPort Server Pro can be used with your existing applications that support serial communication. It
also comes with a utility program providing a simple step-by-step installation procedure, and a
maintenance wizard that gives you easy access to your asynchronous devices.

Knowing Your Application
NPort Server Pro is an advanced Industrial Serial Device Server designed to fit into today's everexpanding networking world. It extends the usage of traditional COM ports on a PC—an isolated
machine with restricted ports—to being able to access the ports over a TCP/IP network. Through the
nature of networking, you are able to control your serial devices from a distance, either over a LAN,
or even over the Internet.
Since NPort Server Pro is connected through a TCP/IP network, you will need to know some basic
facts about networking in order to get the server hooked up correctly. In the next section we discuss
theSingle-Host Mode.
Single-Host Mode
Traditional serial port communication uses a COM port board that slides into one of the slots on the
back of your PC. In this case, only the computer containing the board can access the serial port. With
Moxa’s 8/16-port NPort Server Pro serial device server, communicating with COM ports is much
more versatile, since you are now able to access the COM ports from a distance. For example, the
server could be located in Stockholm, and the serial devices in Frankfurt.
Figure 2-1. Traditional Multi-Port Serial Communication
If you use the type of application described in the previous paragraph, NPort Server Pro with its
Ethernet connection is the best solution available for adding RS-232 serial devices to your computer.
It allows you to extend the range of your operation, increase the number of ports used, and provides
high throughput. The installation procedure is as simple as installing a traditional multi-port serial
board. You don't have to spend a lot of time learning advanced networking concepts to configure
NPort Server Pro. The least you will need to do is install an Ethernet card in your computer.

Figure 2-2. Single-Host Mode using two NPort Server Pros
Multi-Host Mode
For advanced applications you may share one NPort Server Pro with multiple hosts on a Local Area
Network(LAN).Unlikeserialdevicesbundledtoa dedicated host, sharing one NPort Server Pro
with several computers saves resources, since you no longer need to add multi-port serial boards to
each computer. Figure 2-3 shows the basic concept of the Multi-Host application.
For example, let’s assume that you have three hosts on the same network, and each host requires 5
serial ports to communicate with five serial devices. All you need to do is install one 16 port NPort
Server Pro, and connect 5 ports to each of the three hosts. In some types of applications,suchasa
modem pool, or other RS-232 device pooling situations, you can allow different hosts to access the
same serial devices. The TCP/IP protocol automatically handles the time-sharing problem introduced
by this type of application.

TCP/IP
Figure 2-3. Three-Hosts sharing two NPort Server Pros
If you decide to configure your NPort Server Pro as Multi-Host, you will need to know something
about the networking concept of assigning IP addresses. There are two basic roles at play with this
application mode—the administrator, and general users. The administrator assigns a dedicated IP
address to NPort Server Pro, so that other Windows NT/95/98 hosts on the network, i.e., the general
users, are able to locate the server that is being administered. The administrator also decides who has
the right to access which ports. General users only need to install the driver and software, add NPort
Server Pro to their system, and then run their application. These procedures protect NPort Server
Pro’s security, and help keep the server running as a clean, simple device for serial communication.
. Note: Multi-Host Mode is designed to be used only at the local level, such as over a LAN.

Custom Mode
The Custom Mode of operating NPort Server Pro allows for situations more complex than those
mentioned in the two previous subsections. These functions include remote control from an Internet
host, setting the ports on NPort Server Pro as WAN ports for remote control, and adding complicated
routing protocols. Setting up these types of application requires more network knowledge, and
possibly knowledge about the Internet and Intranet. Figure 2-4 shows a complex remote-control
example.
In most cases, if NPort Server Pro is used for remote access or control, you will need to customize the
server to suit your needs. You could be the administrator setting up NPort Server Pro for other
Windows NT/95/98 hosts, or you could be a general user with access to NPort Server Pro from a
remote site.
Connecting the Hardware
In the previous section we illustrated the general operation modes of NPort Server Pro. In this section
we begin by describing how to find a proper location for your server, and then explain how to
connect to the network, hook up the power cable, and connect to the server’s serial port.
NPort Server Pro User’s Manual 2-5
Locating NPort Server Pro
There are two placement options available. NPort Server Pro can be:
q
q
placed on a desktop,
fixed to a 19-inch rack-mount.
Desktop
This option involves placing NPort Server Pro on a clean, flat, well-ventilated desktop. There are four
rubber pads fixed to the bottom of the server, and we recommend leaving sufficient room between
NPort Server Pro and neighboring equipment to create clearance for air to circulate.
. Note: Please remember to not put anything on top of NPort Server Pro, since this could
damage the internal components.
Rack Mount
NPort Server Pro can also be mounted on a standard 19-inch rack-mount. First use four screws to
attach the L-shaped brackets to the server. Next, attach the server to the rack-mount with two screws,
as shown below.
Figure 2-5. Rack Mount

NPort Server Pro User’s Manual
Getting Started
Connecting to the Network
There are two ways to use the 10/100BaseT Ethernet jack located on NPort Server Pro’s back panel
(see Figs. 1-3 and 1-4):
1.
For many of the applications using NPort Server Pro, you will simply plug one end of
your Ethernet cable into the 10/100BaseT jack, and the other end into the hub
connected to your network.
2.
In some cases, such as when configuring drivers and software, you will find it
convenient to hook NPort Server Pro directly to your computer’s Ethernet card. To do
this you will need to use a “crossed-cable”, such as the one supplied with your server.
Connecting the Power
After connecting NPort Server Pro to your network, you should take the following steps to connect
the power cable.
NPort Server Pro’s power supply is designed to support 90-260V AC, making it possible for you to
use the server regardless of your AC power supply’s voltage.
. Note: It is strongly recommended that NPort Server Pro be connected to the network before
turning on the power.
1.
Connect the power cord to NPort Server Pro’s rear panel.
2.
Plug the other end of the power cord into an electrical outlet.
3.
Turn the on/off switch to the I–position.
4.
Check the power LED on the front panel to verify that the server is receiving power.
Connecting Asynchronous Serial Devices
You may use the RJ-45 to female DB-25 cable included with NPort Server Pro to connect serial
devices to the server. Plug the RJ-45 connector into one of the serial port jacks on the server’s rear
panel, and then connect the DB25 connector to the serial device.
Refer to Appendix C for details on NPort Server Pro’s RJ-45 pinouts to make your own cable.
. Note: You can also use the RJ-45 to male DB25 cable to connect the server to a modem.
Check with Appendix C for pinout details to make your own modem cable.

IP Address Configuration
In this chapter we explain how to configure NPort Server Pro’s IP address, using:
q
Telnet Console
q
DHCP Server
The first method uses the Telnet program to access the server over the network. The second method
applies if you have a Dynamic Host Configuration Protocol (DHCP) server.
NPort Server Pro User’s Manual
3-1
Telnet Console
You may use the Telnet program to easily communicate with NPort Server Pro over a TCP/IP
Ethernet network. All you need is the server’s current IP address and a computer running the Telnet
program, provided the computer is hooked up to the server’s network. The example in this section
was generated using a Windows NT/95/98 host.
. Note: After activating the Telnet Console, you will need to use the keyboard keys to
maneuver about the VT100 screen.
3-2
q
While in the Telnet Console MAIN MENU, the left/right arrow keys move the cursor
between menu headings, and pressing the Enter key activates whichever menu heading
is highlighted.
q
After pressing Enter from the MAIN MENU, the Tab key and up/down arrow keys are
used to move between configurable options.
q
The Esc key is used to maneuver backwards. For example, if you have made
modifications to the settings listed under the serverConfig menu, press the Esc key to
return to the MAIN MENU.
q
Carry out the following procedure to configure the server’s IP address.
1.
From the Windows NT/95/98 desktop click on Start and then choose Run.
2.
Type telnet [IP_address] in the Open text input box, where
[IP_address] is the IP address of the NPort Server Pro you intend to configure.
Click OK to continue.
3.
When the Telnet window opens up, type 1 to select ansi/vt100 for Console terminal
type, and then press Enter on the computer keyboard.
NPort Server Pro User’s Manual
IP Address Configuration
4.
A connection between your computer and NPort Server Pro should now be established,
and the MOXA NPort Server Pro utility program will automatically start running.
. Note: After activating the Telnet console, use the following procedure to make sure that the
VT100 Arrows option is selected. Not doing so could cause the server’s name to be
changed inadvertently.
5.
Choose Preferences from the Telnet Console Terminal menu.
6.
Make sure that the VT100 Arrows box in the lower left hand corner of the window is
checked, and then click OK to return to the Telnet Console window.
7.
Use the keyboard arrow keys to highlight [serverConfig] as shown below, and then
press Enter to select this option.
NPort Server Pro User’s Manual 3-3
8.
Use the keyboard arrow keys to position the cursor over the first digit of the IP address.
9.
Type in the correct IP address and then press Enter to accept this value.
10. Press ESC to return to the main menu, and then select Restart to activate the change.
DHCP Server
This section applies if you are using your Windows NT host as a DHCP server. This type of server is
set up to provide IP addresses for new devices as they log onto a network. As the operation of NPort
Server Pro requires a fixed IP address, we strongly recommend that you establish an IP reservation
list in DHCP in order to maintain fixed IP assignments based on the server’s MAC address. NPort
Server Pro’s unique MAC address, which is required when setting up the DHCP server, can be found
on the server’s back panel.
. Note: For NPort Server pro, the DHCP setting is ENABLED by default.
1.
Access DHCP Manager from the Windows NT desktop by clicking on
Start à Programs à Administrative Tools à DHCP Manager.
3-4
NPort Server Pro User’s Manual
IP Address Configuration
2.
The left info box of the DHCP Manager window will show a list of DHCP hosts
currently hooked up to the network.
Note that before you can make changes to the host’s parameters, there must be a minus
sign (–) located to the left of the server name (Local Machine in the example shown
below.) If, as shown, there is a plus sign (+) to the left of the server name, use the left
mouse button to click on the name of the host until the minus sign appears.
3.
You must now define the DHCP server “scope”.
A scope is simply a range of IP addresses that the server assigns to machines as they
log onto the network. Since the assignment is dynamic, the IP address assigned to a
particular device can change each time the device is logged in. What we will do is use
DHCP Manager to set aside a specific IP address that will always be assigned to your
NPort Server Pro when it is hooked up to the network. When the device is not hooked
up, the reserved IP address is not used.
If you have already defined a scope, continue with step 5 below.
4.
To get started, click on DHCP Options and then chose Scope from the pull down
menu.
NPort Server Pro User’s Manual 3-5
5.
Once the Create Scope (Local) window opens (see below), you will be required to
input a range of IP addresses in the IP Address Pool.
There is also an Exclusion Range used to prevent the DHCP server from issuing
addresses to existing devices that have already been assigned IP addresses from this
range. By using the Add and Remove buttons, several different ranges can be excluded,
and later included.
3-6
6.
Another item that must be attended to is the Subnet Mask. This is a number that is
combined with a device’s IP address to determine which subnet the device belongs to.
For a Class C address you should input 255.255.255.0, and for Class B addresses use
255.255.0.0.
7.
Make sure the Unlimited option under Lease Duration is checked. This prevents the
system from automatically disconnecting devices that are using IP addresses in the
specified range.
8.
Assign a name to the scope, and if you would like, include a comment. Click OK to
accept the values.
NPort Server Pro User’s Manual
IP Address Configuration
9.
A window opens with the question: Activate the new scope now? Click on Yes to
activate.
At this point we explain how to input a unique IP address reserved exclusively for use
by your NPort Server Pro.
10. From the DHCP Manager – (Local) menu bar, click on Scope, and then select Add
Reservations.
11. The Client Properties window that opens contains text input boxes for IP address,
Unique Identifier, Client Name, and Client Comment. First enter the selected IP
address, and then locate and enter your NPort Server Pro’s MAC address in the Unique
Identifier field. (The MAC address is located on NPort Server Pro’s back panel.)
Be sure to enter the same Client Name that was entered in the Name field of the
Create Scope - (Local) window (see step 8 above). The Client Comment is optional.
At this point you should double-check the MAC address and IP address, and then click
OK to accept the values.
NPort Server Pro User’s Manual 3-7
12. To check that the numbers just entered are correct, return to the DHCP Manager main
window, click on Scope, and then choose Active Leases from the pull down menu.
The IP address reserved for your NPort Server Pro will be displayed in the window that
opens up. Check to make sure that it is accurate.

drive, and then install the new one.
Replacing a Server
In the unlikely event that your NPort Server Pro needs to be replaced, you can use NPort Pro
Manager’s Replace Server… function. This procedure uses NPort Server Pro’s “hot-swap” feature,
and gives you an easy way to locate the replacement server. The configurations that were set while
installing the now defective server will also be saved. Otherwise, you would need to use NPort Pro
Manager to delete the old server, and then configure the new server and all of its ports.
Follow the steps below to perform hot-swap:

After running Add Server Wizard and typing in your password showing that you are the
administrator, you are granted access to the server you have added. You may go to server properties
to check that. However, if you did not enter the correct password, you can still map the ports to your
NT/95/98, but you will not have access to the ports. You will need to ask your administrator to add
your IP address to the access control list of the server to grant you access. If you are not sure of the IP
address of the host you want to add, run ‘ipconfig’ from the host’s NT/95/98 MS-DOS prompt.

Server Properties—Transmission
The Transmission page allows the user to set the Transmission Mode and TxFIFO options for each
of NPort Server Pro’s ports.
Transmission Mode
SelectHi-Performance to use buffering technology to accelerate data writing. This allows your
communication software to reach maximum data throughput when transmitting large amounts of data.
The driver will notify the user that the transmission is completed when the output data length is lower
than the LOW WATER setting.
Classical Mode lets the port behave like a generic COM port. Transmission of small data packets is
more precise and reliable. In this case, the driver will notify the user that the transmission is complete
when all data has been transmitted.
NPort Server Pro User’s Manual 6-17
Tx FIFO
Set to Enable to the get the best performance from the board.
Set to Disable to avoid data loss when communicatingwithplaincommunicationdevicesusingS/W
flow control. In this case only one byte will be put into the UART when the FIFO is empty.
Access Control
It is possible to assign access permission to hosts to allow them access to the ports on a shared NPort
Server Pro. For security reasons, the access control list can only be defined by the server’s
administrator. If you have not been granted access to a port, youwillseeascreenwiththemessage
‘Non-authorized’ for that port.
After running Add Server Wizard and typing in your password showing that you are the
administrator, you are granted access to the server you have added. You may go to server properties
to check that. However, if you did not enter the correct password, you can still map the ports to your
NT, but you will not have access to the ports. You will need to ask your administrator to add your IP
address to the access control list of the server to grant you access. If you are not sure of the IP address
of the host you want to add, run ‘ipconfig’ from the host’s NT MS-DOS prompt.
. Note: If you empty the access control list, then by default, only the connecting host’s IP
address is granted.

hosts. The next two sections describe how to add hosts using both approaches.
Configuring Through View by IP
Using the view access control list by IP address option displays the access control list by giving the
server IP addresses. It is clear to see which IP addresses have been granted access to which ports, and
which IP addresses are allowed onto the server.

Changing Your Installation Type
This chapter describes how to change between the three application modes — Single-Host, Multi-Host,
and Custom—after installation. The only way to change from one application mode to another is to
rerun the driver/software Setup program
If you started off by installing your serverasSingle-Host, you will have noticed, for one thing, that it
is not possible to change the server’s IP address from this application type. If at some point during the
server’s operation you find it necessary to change the IP address, share the ports with another
NT/95/98 server, or initiate some type of remote control function, you will need to change to a
different application mode.
Note that changing between application types will not automatically wipe out previously set
configurations. Be sure toselect the correct mode for your application. See chapter 2 of this manual
for details.
. Note: To change to a different application mode, you will need to rerun the Setup program.

Installation and Configuration Troubleshooting
¿
Cannot use the first computer installed with the Single-Host NPort Pro Manager to access
NPort Server Pro.
For security reasons, and to simplify operations, the Single-Host Mode allows only one host to
connect to NPort Server Pro at a time. Thus, if while using the single-host type of installation you
discover that the server has already been configured with password protection, it is advised that you
check to see if two or more NT/95/98 hosts are sharing the same NPort Server Pro configured for
Single-Host Mode. If you wish to use more than one host to access the same NPort Server Pro, you
will need to install NPort Server Pro under Custom Mode.
NPort Server Pro User’s Manual
A-1
¿
Cannot change IP address or other server properties.
There are two situations that could give rise to this problem.
¿
¿
1.
Password Mismatch – If you type the wrong password while running NPort Pro
Manager, the Manager program automatically assumes that you are not the
administrator. The administrator of the server is the only one allowed to modify the
server’s configuration. Keep in mind that even when multiple hosts share the same
server, access to the server’s administrative functions is still protected. If you need to
change some configuration settings, you will have to ask your administrator for help. If
you are the administrator but forget the password, you can erase the current password
yourself by pressing the RESET key on NPort Server Pro’s back panel for three
seconds.
2.
Error Installation Type – You cannot change the server IP address if you are installing
NPort Server Pro under Single-Host Mode. Setting the installation procedure up in this
way makes the Single-Host Mode configuration procedure very similar to installing a
traditional multi-port serial board. Under Single-Host Mode, users are only allowed to
modify the server's name and password. This is because Single-Host users are not
sharing their NPort Server Pro with other hosts. If you do need to modify other
properties, run the setup program and change to another mode of operation (see
Chapter 8 for details).
You would like to allow one more host to access your NPort Server Pro, but are unable to
reach the page for Access Control.
1.
Check the NPort Manager mode. If it is Single-Host Mode, reinstall it as either MultiHost Mode or Custom Mode.
2.
Double check your credentials to make sure that you are the administrator.
After installing NPort Server Pro, the NPort Pro Manager program indicates “'Unauthorized” status for some of the ports.
This means that NPort Server Pro’s Access Control List does not contain your computer’s correct IP
address. This can happen in one of two ways:
A-2
1.
Your NT/95/98 machine is just one of the hosts sharing the ports on the selected server,
and you do not provide the server password while installing NPort Server Pro.
2.
You install NPort Server Pro at a local site, with no access problems, but later move the
server to a remote site and connect through a WAN. Due to the different network
interface connection, your IP address might have changed, and as a consequence, you
are no longer on the server’s Access Control List.
NPort Server Pro User’s Manual
Troubleshooting
To solve this problem:
¿
1.
Confirm your IP address with NPort Server Pro.
2.
Ask the administrator to set up the server configuration so that you are on NPort Server
Pro’s Access Control List.
While running NPort Pro Manager, a question mark, '?', shows up on top of the server icon,
and you are unable to enter server properties.
This means that the host cannot find the server. Here are some steps you can take to recover from this
problem:
If the host and server are in the same location:
1.
Make sure NPort Server Pro’s power cable is plugged in, and the server is receiving
power.
2.
Check that the server’s network connector is plugged in properly.
3.
Make sure your computer is properly connected to the network.
4.
Double click on the server icon that has the question mark (?) on top. This will evoke
NPort Pro Manager to reconnect with the server.
If the server is at remote site:
1.
Make sure the network connection to the remote site is okay. If no route can be
established to the remote server, and you are connecting through the Internet, you may
need to wait until the route is reestablished.
2.
If the route is okay, try running
ping [server-IP-address]
from your NT host, where [server-IP-address] is the server’s IP address. If the
server cannot be pinged, you will need to ask someone at the remote site to check and
see if the power is on, and make sure that the connection is okay. And then double
click on the server icon that has the question mark (?) on top. This will evoke NPort
Pro Manager to reconnect with the server.
If the problem is still not fixed, contact Moxa technical support for further information.
NPort Server Pro User’s Manual

¿
You cannot find the server after rebooting your Windows NT/95/98 server.
It’s possible that you have a DHCP server on your network. Since DHCP servers can assign IP
addresses, the IP address for either the host or NPort Server Pro might have been changed. To recover
from this problem, you should:
1.
Ask the administrator of your DHCP server to assign a dedicated IP address to both
your Windows NT/95/98 host and to NPort Server Pro.
2.
Make sure your NPort Manager Pro operating mode is either Multi-Host or Custom.
3.
Change the IP address of the server to the dedicated IP address assigned by your DHCP
administrator.
4.
Change the IP address of your Windows NT/95/98 host to the dedicated IP address
assigned by your DHCP administrator.
. Note: Please refer to Appendix D to learn how to configure your Windows NT/95/98 to the
dedicated IP address.
5.
Modify the Security list to include your NT/95/98 host.
6.
Save Configuration.
Programming Problems
¿
Win32 COMM API functions return fail, or the PComm Pro library functions return a Fail
code - SIO_WIN32FAIL
The fail code for the COMM API functions implies something different than the fail code received
from the standard COM driver. For example, you get the fail code when the network connected to the
server is unreachable, or the server is offline. If the network connection is through the Internet, the
network could be unreachable if Internet traffic is jammed. This does not mean you have a defective
server. Torecover from this type of error, you can modify your program so that the port is
automatically closed and then re-opened.
You should also check the following to make sure that the problem is only with the TCP/IP network:
1.
If the server is off-line, turn it on.
2.
If the route to NPort Server Pro is reachable, you may test it by using
Ping [NPort-Server-Pro-IP-address]
If a route to the server cannot be established, check your routing table or the server's
routing table.
A-4
NPort Server Pro User’s Manual
Troubleshooting
To solve this problem, programs should:
1.
Try to re-open the port if the fail code is returned during the open (i.e. sio_open)
session.
2.
If the fail code returns while writing data, reading data, changing settings, etc., you
should close the file handler, and then try to open the port again.

PComm Pro is a professional serial comm developing tool for PCs running Windows NT or
Windows 95/98. It consists of a powerful serial communication library for easy programming in most
popular programming languages. Furthermore, it contains useful utilities, such as Terminal Emulator,
Data Scope, and Performance Analyzer, as well as illustrative example programs and comprehensive
online documents.
With the serial communication library, you can develop systems for data communication,remote
access, data acquisition or industrial control in the Windows NT and Windows 95/98 environment.
PComm Pro offers an easier solution as compared to the more complex Windows Win32 COMM
API.
PComm Pro includes over 50 easy-to-use API functions specially designed for serial comm., and
prevents you from struggling with sophisticated Microsoft Win32 API. Hence, it greatly saves
developing time and cost. (The API functions can be used for any serial comm hardware that
supports Microsoft Win32 driver, e.g. DIGI boards, standard com ports, etc.)

D. Setting Up a Windows NT/95/98 Network
In order use a PC via an Ethernet network to control serial devices connected to NPort Server Pro,
you must first have a host running Windows NT/95/98 This type of application also requires the host
to have an Ethernet card and TCP/IP protocol installed. If your computer does not already have an
Ethernet card installed, you will need to purchase one, and then follow the instructions provided by
the Ethernet card manufacturer to install and set up the card.
. Note: We recommend installing a PCI Ethernet card on your NT/95/98 host. Because of the
BUS difference, a PCI bus Ethernet card will perform much better than an ISA
Ethernet card. The PCI card reduces system loading under high speed and multiple
port usage.
