1 Overview
Welcome to Moxa NPort Server Lite, 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.
This chapter is an introduction to NPort Server Lite and includes the following:

Features
Package Checklist
Top/Front/Rear View
NPort Server Lite provides a data communication solution for connecting Windows
NT/95/98 hosts to multiple asynchronous RS-232 (models DE-302/304) or RS-422/485
(models DE-332/334) serial ports through a TCP/IP network. Each model has two
(DE-302/332) or four (DE-304/334) asynchronous serial port connections on one side, and
one 10/100M Ethernet connection on the other, allowing any device that supports primarily
the asynchronous communications protocol to attach to a network. NPort Server works like
an add-on multiport serial board to the NT/95/98 server, but with one major advantage – the
TCP/IP network. Since the Windows NT95/98 host communicates with the COM ports on
Nport Server Lite 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 Lite
are recognized as real COM ports by the Windows NT/95/98 operating system. NPort
Server Lite provides both the basic transmit/receive data functions, as well as RTS, CTS,
DTR, DSR, and DCD control signals.
NPort Server Lite 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 Lite is an advanced Industrial Serial Device Server designed to fit into today's
ever-expanding 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 can control your serial devices
from a distance, either over a LAN, or even over the Internet.
Since NPort Server Lite 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 this
section we discuss the Host-Based Mode application.
Host-Based 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 2/4-port NPort Server Lite 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.

Getting Started
Connecting the Hardware
In the previous section we illustrated the general operation mode of NPort Server Lite. We
begin this section 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.
Choosing a Location
There are three placement options available. NPort Server Lite can be:
·
·
·
placed on a desktop,
fixed to a wall or inside a cabinet, or
fixed to a 35-mm DIN Rail.
Desktop
One option is to place NPort Server Lite on a clean, flat, well-ventilated desktop. There are
four rubber pads attached to the bottom of the server, and we recommend leaving sufficient
room between NPort Server Lite and neighboring equipment to create enough clearance for
air to circulate.
You should also remember not to put anything on top of NPort Server Lite, since this could
damage the internal components and obscure the server’s LCD panel.
Wall or Cabinet
The two metal brackets included with NPort Server Lite can be used to attach the server to
a wall, or the inside of a cabinet. Using three screws per bracket, first attach the brackets to
the bottom of the server (Fig. 2-2a). Next use two screws per bracket to attach the server to
a wall or cabinet (Fig. 2-2b).

Figure 2-2b. NPort Server Lite—Wall Mounting Brackets (top view)
DIN Rail
Figure 2-3. Din Rail Mounting Bracket
NPort Server Lite can also be mounted on a standard 35-mm DIN Rail. First use two
screws to attach the DIN Rail bracket to the metal plate (Fig. 2-3). Since the screw heads
are beveled, and the holes in the plate are countersunk, the tops of the screws will be flush
with the metal plate.
Figure 2-4. Din Rail Mounting Bracket—Orientation of Metal Plates
This allows the metal plate (now with the DIN Rail bracket attached) to be screwed to the
bottom of the server in such a way that it does not stick out over the edge of the server. Use
three screws to attach the metal plate to the bottom of NPort Server Lite, with the
orientation as shown in Fig. 2-4.

Getting Started
Network Connection
There are two ways to use the 10/100BaseT Ethernet jack located on NPort Server Lite’s
front panel (see Fig. 1-2):
1. For many of the applications using NPort Server Lite, 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 Lite 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.
Power Connection
You should take the following steps to connect NPort Server Lite’s power adaptor.
1. Connect the power adpator’s DC plug into NPort Server Lite’s “DC-IN” jack.
2. Connect the power adaptor to an electrical outlet.
Note that there is no on/off switch. The server automatically turns on when plugged into the
outlet.
If the server is working properly the LCD panel back light will glow for a few seconds
before shutting off, and the green PWR LED will also light up, indicating that the server is
receiving power. The LCD panel should look similar to what is shown in Figure 1-1.
Serial Connection
The model of NPort Server Lite that you purchased has either two (models DE-302/332) or
four (models DE-304/334) DB9 serial port jacks on the back panel (see Fig. 1-3).
Depending on your serial device and serial interfaces, there are two options:
1. For an RS-232 port you may use a DB9 to DB9 cable to connect your serial device to
NPort Server Lite. Simply plug one end of the cable into the jack on the back panel of
the server, and plug the other end into the serial port jack on your serial device.
2. Refer to Appendix C for details on NPort Server Lite’s DB9 pinouts, and then make
your own cable.

Preparing Windows NT/95/98 for a TCP/IP Network
In order use a PC via an Ethernet network to control serial devices connected to NPort
Server Lite, 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.
IP Address Configuration
You may choose from three different methods to configure NPort Server Lite’s IP address.
The first method, using the server’s LCD Panel, simply requires plugging the server into an
electrical outlet.
LCD Panel
The LCD buttons on NPort Server Lite’s top panel are manipulated in a manner similar to
the way a modern cellular phone is operated. (See Appendix B for a complete description
of how to use the LCD buttons.) As you move through the various functions and setting
options, note that the top line shows the current menu or submenu name, and the bottom
line shows the submenu name or menu item which is activated by pressing SEL.
We would like to set the IP address. To do this you should:
1. Plug in the power cord (if necessary, see the section Connecting the Hardware from
Chapter 2 for complete instructions), and then press MENU once, after which you
should see the MAIN MENUscreen:
M A I N
M E N U
S E T T I N G

S E T T I N G
•
¯
I P A D D R R E S S
4. Press SEL again, after which the default IP address will be displayed. Note that the first
digit of the IP address will be highlighted by a blinking cursor, indicating that it can be
edited:
I P
A D D R R E S S
•
¯
1 9 2 . 1 6 8 . 1 2 7 . 2 5 4
The SEL button now acts as the right cursor, the r button decreases the selected digit,
and the s button increases the selected digit.
Keep in mind that there is no left cursor button. If you accidentally press SEL, moving
the blinking cursor to the right before inputting the correct digit, you will need to press
MENU, and then start over at step 3.
You will notice that the displayed numbers are automatically limited to the range
required for IP addresses. For example, the first digit of each of the four numbers can
only be 0, 1, or 2.
5. Use the functions described above to enter the server’s IP address. After changing the
last digit, the blinking cursor will be all the way to the right, highlighting the last digit
of the number.
6. Press SEL to return to the screen shown in step 3. (To change the number, press MENU
and then start over at step 3 above.) To accept the number, press MENU twice, after
which the LCD screen displays
S A V E
N O
C H A N G E ?
¯
7. Press SEL to NOT save the setting, or press r to change to the following screen:
S A V E
Y E S
C H A N G E ?
¯
8. Press SEL to save the setting. At this point the system will restart, and then return to the
default screen showing the server’s name, serial number, and IP address.

Telnet Console
Depending on the way your computer and network are set up, you may find it convenient,
or even necessary, to set up NPort Server Lite over a network. This can be done using the
Telnet program.
In the following discussion, we assume you are using a Windows NT/95/98 host.
1. From the Windows NT/95/98 desktop click on Start and then select Run.
2. In the Open text input box, type
telnet [IP address]
where [IP address]is the IP address of the NPort Server Lite which you intend to
configure, and then click OK.
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.
4. A connection between your computer and NPort Server Lit e should now be established,
and the MOXA NPort Server Lite utility program will automatically start running.

5. Use the keyboard arrow keys to highlight [serverConfig] as shown below, and then
press Enter to select this option.
6. A window showing the various parameters required to configure NPort Server Lite
opens up. Those parameters that are “configurable” are enclosed in square brackets,
and those parameters that are “display only” are not enclosed.
7. Since our goal in this section is to set the IP address of the server, use the keyboard
arrow keys to position the cursor over the first digit of the IP address.
8. Type in the correct IP address and then press Enter to accept this value.
9. Press ESC to return to the main menu, and then select Restart to activate the change.
NPort Server Lite User’ s Manual 3-5

DHCP Configuration
This section is applicable if you are using your Windows NT host as a DHCP server, where
DHCP stands for Dynamic Host Configuration Protocol. This type of server is set up to
provide IP addresses for new devices as they log onto a network (hence the Dynamic part of
the name). As the operation of NPort Server Lite 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 Lite’s unique MAC address
can be found on the server’s back panel, or by using the LCD panel to access the server’s
memory. (See Appendix B for details.)
1. Access DHCP Manager from the Windows NT desktop by clicking on
Start àPrograms àAdministrative Tools àDHCP Manager.
2. The left side 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 below, there is a plus sign (+) to the left of the server name, use
the left mouse button to click on the name until you see the minus sign appear.
3-6 NPort Server Lite User’ s Manual

Configuring the Network
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 logs 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 Lite 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 6 below.
4. To get started, click on DHCP Options and then chose Scope from the pull down
menu.
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.
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.
NPort Server Lite User’ s Manual 3-7

8. Assign a name to the scope, and if you like, include a comment. Click OK to accept
the values.
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 Lite.

Configuring the Network
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 Lite’s MAC address in the
Unique Identifier field.
(The MAC address is located on NPort Server Lite’s back panel, or see Appendix B for
an explanation of using NPort Server Lite’s LCD buttons to locate the MAC address.)
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.

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 Lite will be displayed in the window
that opens up. Check to make sure that it is accurate.

Replacing a Server
In the unlikely event that your NPort Server Lite needs to be
replaced, you can use the Replace Server… option listed under
NPort Server Lite Manager’s Server menu. This procedure
uses NPort Server Lite’s “hot-swap” feature, and provides an
easy way for you to find the replacement server. The
configurations set while installing the now defective server will
also be saved. Otherwise, you would need to delete the old server from NPort Server Lite
Manager, and then configure the new server and all of its ports.
1. Move your mouse pointer to the server that has a
question mark (?) on top of it.
2. Click on the Server menu, and then select Replace
Server….
3. The Replace Server window that opens up shows a list
of servers that you have not configured. You can
identify the new server by looking at the serial number.
4. Confirm the Server with the pop up window.
5. If the new server is password protected, enter
the pre-set password when prompted to do so.
6. Click OKto save the current settings to the
new server.
7. Click on Save Configuration to activate.
.
Note: Previous configurations, including server name and port settings, are retained after
going through the above described Replace Server procedure. However, the server
password will be set to the one you entered during the replacement procedure, so you
will need to start using the new password to access the server.

Granting Access to Hosts
It is possible to assign access permission to hosts to allow them access to the ports on a
shared NPort Server Lite. For security reasons, the access control list can only be defined
by the server’s administrator. If you have not been granted access, you will see a screen
with the message ‘Non-authorized’ for the ports.
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.

Installation and Configuration Troubleshooting
Cannot use the first computer installed with the Single-Host NPort Server Lite Manager to
access NPort Server Lite.
For security reasons, and to simplify operations, the Single-Host Mode allows only one
host to connect to NPort Server Lite 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 Lite configured for Single-Host Mode. If you wish to use more than one
host to access the same NPort Server Lite, you will need to install NPort Server Lite under
Custom Mode.
Cannot change the 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 Server Lite
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 simply pressing the RESET key on NPort Server Lite’s back panel for three
seconds.
2. Error Installation Type – You cannot change the server IP address if you are
installing NPort Server Lite 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 multiport 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 Lite with other hosts. If you do need to modify other
properties, run the setup program and change to another mode of operation (see
Chapter 4 for details).
You would like to allow one more host to access your NPort Server Lite, 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
Multi-Host Mode or Custom Mode.
2. Double check your credentials to make sure that you are the administrator.

Troubleshooting
After installing NPort Server Lite, the NPort Server Lite Manager program indicates
“'Un-authorized” status for some of the ports.
This means that NPort Server Lite’s Access Control list does not contain your computer’s
correct IP address. This can happen in one of two ways:
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 Lite.
2. You install NPort Server Lite 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.
To solve this problem:
1. Confirm your IP address with NPort Server Lite.
2. Ask the administrator to set up the server configuration so that you are on NPort Server
Lite’s Access Control list.
While running NPort Server Lite 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 Lite’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 Server Lite Manager to reconnect with the server.
If the server is at a 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.
NPort Server Lite User’ s Manual 6-3
Download from Www.Somanuals.com. All Manuals Search And Download.
2. If the route is okay, try running
ping [server-IP-address]
from your NT/95/98 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
Server Lite Manager to reconnect with the server.
If the problem is still not fixed, contact Moxa technical support for further information.
You cannot find the server after rebooting your Windows NT/95/98 host.
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 Lite 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 Lite.
2. Make sure your NPort Server Lite Manager 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 Chapter 3 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.

Troubleshooting
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. To recover from this type of error,
you can is 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 Lite is reachable, you may test it by using
Ping [NPort-Server-Lite-IP-address]
If a route to the server cannot be established, check your routing table or the server's
routing table.
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.

A.Telnet Console
This appendix contains instructions and illustrations that explain how to use Telnet Console
Interface. The following discussion and examples were generated by running Telnet from a
Windows NT/95/98 host.
Starting Telnet
From the Windows NT/2000/95/98 desktop click on Startand then choose Run.
As shown below, type
telnet [NPort Server Lite IP address]
in the Open text box, where [NPort Server Lite IP address]is the NPort Server
Lite’s IP address, and then click OK to begin the Telnet session.
NPort Server Lite User’ s Manual A-1
Download from Www.Somanuals.com. All Manuals Search And Download.
You should see a window requesting the Console terminal type you would like to use.
Type 1 for ansi/vt100 and then press Enter.
This activates the Telnet Console Interface utility program. In what follows we refer to the
screen shown below as the Telnet Console Interface MAIN MENU.
Navigating the Telnet Console
After activating the Telnet Console, you will need to use the keyboard keys to maneuver
about the vt100 screen. The operation is really quite simple.
q
q
While in the MAIN MENU, the left/right arrow keys move the cursor between menu
headings, and pressing the Enter key activates whichever menu heading is highlighted.
After pressing Enter from the MAIN MENU, the Tab key and up/down arrow keys
are used to move between configurable options.
The left/right arrow keys are used to “move through” certain configurable settings
without actually changing anything. To modify a setting, such as a device name or IP
address, both of which have a very large number of possible settings, use the
appropriate letter and number keys on the keyboard.
The Enter key is used to open a menu containing a small number of options (Yes and
No, for example) for configurable settings which have only two or three possible
settings. The up/down arrow keys move the cursor between the options, and the Enter
key is used to select the option that is highlighted.

Telnet Console
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.
When you first activate the Telnet Console Utility’s MAIN MENU, you may find that the
arrow keys on your keyboard initially have no effect on the cursor. If that’s the case, first
click on Terminal, located on the Telnet menu bar, and then choose Preferences.
The Terminal Preferences window opens up, allowing you to select various options that
affect the function of the keyboard. Make sure that the box next to VT100 Arrows (in the
lower left hand corner of the window) is checked, and then click OK to return to the Telnet
Console window.
Telnet Console Menu Functions
The Telnet Console MAIN MENU has seven menu categories related to the operation of
NPort Server Lite. They are: serverConfig, Serialport, Diagnostic, Monitor, Ping,
Restart, and Exit. In this section we describe their purpose and use.
serverConfig Options
Using the left/right arrow keys, maneuver the cursor so that severConfig is highlighted,
and then press Enter to display twelve NPort Server Lite attributes. Note that the attribute
names are listed in the left column, and the current settings are given to the right of each
name.
NPort Server Lite User’ s Manual A-3
Download from Www.Somanuals.com. All Manuals Search And Download.
Attributes that can be edited are enclosed in square brackets, and those that can’t be edited
are not enclosed in brackets. Furthermore, there are two types of configurable attributes,
those with a large number of possible settings, and those with only two or three possible
settings.
Consider Server Name for example. To change the name of your NPort Server Lite, use
the keyboard arrow keys to position the cursor over the first character of the current name.
Simply type in the new name, and then use the arrow keys to move to the next configurable
setting.
As a second example consider DHCP. There are two options for this attribute.
Using the arrow keys, position the cursor so that the current DHCP setting is highlighted.
For the example shown below the current setting is Disable.

Telnet Console
Press Enter to activate a pop up window displaying the two DHCP options (shown below).
Use the up/down arrow keys to highlight the desired setting, and then press Enter. The
new setting, enclosed in square brackets will appear to the right of Operating Mode.
If you find that you chose the wrong setting, simply press Enter again to reactivate the
pop-up window, and choose the correct setting.
When all of the settings are correct, press the Esc key to return to the MAIN MENU.

Serialport Options
Starting from the Telnet Console Interface MAIN MENU, use the arrow keys to position
the cursor over the Serialport menu, and then press Enter to display the configurable
options RS-422/485 Interface, RS-485 Comm. Mode, and Tx FIFO.
The options are as follows:
·
·
·
RS-422/485 Interface
RS-485 Comm. Mode
Tx FIFO
RS-422 or RS-485
ADDC, By RTS
Disable, Enable
When all of the settings are correct, press the Esc key to return to the MAIN MENU.
Diagnostic
This function simply checks the status of the network connection by running an
q
Asynchronous port controller test, and Asynchronous port loopback test.

Telnet Console
Monitor
The Monitor function displays the following information:
Ping
Ping is a standard network testing function that checks to see if a computer with a particular
IP address is logged onto the network. Highlight Ping and then press Enter to activate the
function. Type the IP address of the device in the space provided and then press Enter.
For the example shown below, we pinged the NPort Server Lite currently connected to the
PC’s Ethernet card.
NPort Server Lite User’ s Manual A-7
Download from Www.Somanuals.com. All Manuals Search And Download.
The program begins sending “packets” of data, and tests the return response. Press Esc to
stop sending, and to receive a short report. In this case the ping was successful. If you try
pinging an IP address for a device not connected to your network, the report will tell that “0
packets were received”.
Restart and Exit
When you are sure that all of your settings are correct, return to the MAIN MENU, and run
Restart. You will be prompted with a warning that your settings are going to be changed.
Press Enter to proceed.
If you decide to reject all of the modifications that you’ve made, return to the MAIN
MENU and run Exit.

B.LCD Panel Configuration
In this appendix we explain how to operate the LCD display using the four buttons on
NPort Server Lite’s top panel. It’s best if your NPort Server Lite is in front of you and
plugged in. (If necessary, see the section Connecting the Hardware from Chapter 2 for an
explanation of how to connect the power cord.)
Basic Operation
If the server is working properly, the LCD panel will display a yellow color for a few
seconds, after which it turns green. The green PWR LED will also light up, indicating that
the server is receiving power. You will see a display similar to:
N P 6 1 4 0 5
S N : 6 1 4 0 5
1 9 2 . 1 6 8 . 1 2 7 . 2 5 4 H
This is where
· NP44444
is the server’s name
· SN:61301
is the server’s serial number
is the server’s default IP address
· 192.168.127.254
· H stands for Host Based Mode;
There are four buttons on the top panel of NPort Server Lite. Going from left to right, the
buttons are:
Button

SEL

The buttons are manipulated in a manner similar to the way a modern cellular phone is
operated. As you move through the various functions and setting options, note that the top
line shows the current menu or submenu name, and the bottom line shows the submenu
name or menu item which is activated by pressing the SEL button.
Detailed Menu Options
The best way to display all of NPort Server Lite’s LCD functions is to use the tree graph
shown in Fig. B-1. There are three main levels (1, 2, and 3), with each level represented by
a separate column.
The first thing to remember is that the MENU button is used to move back and forth between
the LCD panel’s default screen, and main menu screen:
N P 6 1 4 0 5
S N : 6 1 4 0 5
1 9 2 . 1 6 8 . 1 2 7 . 2 5 4 H
M A I N
M E N U
S E T T I N G
S E R V E R
¯
In addition, you only need to remember to:
·
Use the SEL button to move up one level (i.e., left to right on the tree graph)
·
·
Use the MENU button to move down one level (i.e., right to left on the tree graph)
Use the cursor keys, r and s, to move between the various options within a level (i.e.,
up and down on the tree graph).
As you use the buttons to operate the LCD display, you will notice that with very few
exceptions, moving up one level causes the bottom line of the display to move to the top
line of the display. Taking a look at the tree graph, you will also notice that the bottom
three options in level 2, and all of the options in level 3 have either a Cor Dattached.
The meaning is as follows:
· C
=
=
configurable: i.e., you are allowed to change the setting of this option
display only: i.e., the setting for this option is displayed, but it cannot be
changed (this does NOT necessarily mean that the number doesn’t change;
only that you can’t change it)

The part of the LCD operation that still requires some explanation is how to edit the
configurable options.
In fact, you will only encounter two types of configurable options. Back in Chapter 4, for
example, we explained how to use the LCD buttons to change NPort Server Lite’s IP
address. In this case, you change the number one digit at a time. The up cursor r is used to
decrease the highlighted digit, the down cursor s is used to increase the highlighted digit,
and the SEL button is used to move to the next digit. When the last digit has been changed,
pressing SEL is very similar to pressing the enter key on a computer keyboard.
The second type of configurable option is when there are only a small number of options to
choose from. Consider the INTERFACEattribute under PORT SETTINGas an example.
Follow the tree graph to arrive at the following INTERFACEscreen. The first option,
NONE, is displayed, with a down arrow all the way to the right. This is an indication that
there are other options to choose from.
