1.4 Terminologies and Acronyms
The network terminologies used frequently in this manual are defined clearly to help you attain abetter
understanding of the LS100W.
MAC address
On a local area network or other network, the MAC (Media Access Control) address is the computer's
unique hardware number. (On an Ethernet LAN, it's the same as your Ethernet address.)
It is a unique 12-digit hardware number, which is composed of 6-digit OUI (Organization Unique
Identifier) number and 6-digit hardware identifier number. The LS100W has the MAC address of 00-
01-95-xx-xx-xx, which is labeled on the bottom side of the external box.
Host
A user’s computer connected to the network
In Internet protocol specifications, the term "host" means any computer that has full two-way access to
other computers on the Internet. A host has a specific "local or host number" that, together with the
network number, forms its unique IP address.
Session
A series of interactions between two communication end points that occur during the span of a single
connection
Typically, one end point requests a connection with another specified end point and if that end point
replies agreeing to the connection, the end points take turns exchanging commands and data ("talking
to each other"). The session begins when the connection is established at both ends and terminates
when the connection is ended.
Client/Server
Client/Server describes the relationship between two computer programs in which one program, the
client, makes a service request from another program, the server, which fulfills the request.
A server is a computer program that provides services to other computer programs in the same or
other computers, whereas a client is the requesting program or user in a client/server relationship. For
example, the user of a Web browser is effectively making client requests for pages from servers all
over the Web. The browser itself is a client in its relationship with the computer that is getting and
returning the requested HTML file. The computer handling the request and sending back the HTML file
is a server.

included in the package. If power is properly supplied, the [Power] lamp will light up a solid red color.

12
Figure 2-2. Connecting the Power to the LS100W
2.2.2 Connecting to the Wireless LAN
An 802.11b Wireless LAN card is embedded in the LS100W. When power is connected correctly, the card will
automatically search for the Wireless LAN access point and attempt to connect to the Wireless LAN
access point (AP). If the Wireless LAN cable is properly connected to the Wireless LAN access point,
the LS100W will have a valid connection to the Wireless LAN network. A proper connection will be
indicated as follows:
- The [Link] LED lamp on the LS100W front panel will remain solid orange.
- The [Act] LED lamp on the LS100W front panel will blink continuously to indicate that incoming and
outgoing Wireless LAN packets are being transferred
To connect the LS100W to a Wireless LAN access point, users must first set the corresponding
information on the LS100W, such as the SSID of the Wireless LAN access point.
Please refer to the Wireless LAN Settings section in Chapter 3 to set the appropriate parameters for a
Wireless LAN connection.
2.2.3 Connecting to the Device
Connect the serial data cable to the LS100W and the serial device as shown below. Ensure that power
has been correctly supplied to both the serial device and the LS100W.

13
Figure 2-3. Connecting a Serial Device to the LS100W
2.3 Accessing Console Port
There are two ways to access console port of the LS100W depending on whether the user is located
at a local site or at a remote site.
- Serial console:
Local users can connect directly to the serial console port of the LS100W using serial
console/data cable (null-modem cable). The serial port of the LS100W is used as the console port
as well as the data port. To use the serial port as the console port, slide Data/Console switch to
the Console side.
- Remote console:
Remote users can make a telnet connection to the remote console port (port 23) of the LS100W
via TCP/IP network.
Both methods require the user to log into the LS100W in order to continue.
2.3.1 Using Serial Console
1) Connect the one end of the serial console cable to the serial port of the LS100W.

From the command prompt screen, users can set, get and save configuration parameter values using
‘set’, ‘get’and ‘save’command. Users also can exit the console or reboot the device using ‘exit”and
‘reboot’command. The usage of the commands can be found using ‘help’command. For command
usages description, please refer to section 2.4 Command usage.
2.3.2 Using Remote Console
The LS100W provides remote console feature via telnet as well as serial console so that users can
access the LS100W at remote site for configuration and monitoring purposes. The IP address of the
LS100W must be known before users can access the remote console port. The port number for the
remote console is 23, which is a TCP port number assigned for Telnet.
Only one user can log into the remote console or serial console at a time. If the serial console is
established while a remote console is established, current remote console will be halted and no more
remote console will be established until serial console is finished.
To access remote console of the LS100W, please use the step as follows:
1) Run a telnet program or a program that supports telnet functions such as TeraTerm-Pro or
HyperTerminal. The target IP address and the port number should be those of the LS100W.
If required, specify the port number as 23.

16
Type the following command in the command line interface of your computer.
telnet 192.168.1.254
Or run a telnet program with parameters as follows.
Figure 2-7 Telnet program set up example
2) The user has to log into the LS100W. Type the user name and password. A factory default
setting of the user name and password are both admin.
3) If the user logs into the LS100W successfully, the same command prompt screen as the
serial console will be displayed. The user can set, get, save configuration parameters and
exit console, reboot the device as like the serial console.
4) If serial console or the other remote consoles are connected already, new console will not be
established at all.
2.4 Command Usage
The LS100W provides several simple commands for configuration and control of the LS100W. Table
2-2 summarizes command set which LS100W supports.

2.4.1 ‘set’Command
With ‘set’command, users can configure parameter values of the LS100W for each environment.
Basic ‘set’command usage is as follows:
set group par1 [par2 ...] + <CR>
where,
group = 'ip','host','serial' or 'admin'
par1 par2 ... = configuration parameters. Use * to keep a parameter's value
The ‘group’is the category where the parameters should be entered. For example, if users want to set
parameters related to the IP configuration, use set command as shown in the Figure 2-8.
> set ip static 192.168.1.100 255.255.255.0 192.168.1.1
OK
>Figure 2-8 IP configuration example screen
In the above example, the first parameter ‘ip’ indicates that the following parameters are IP
configuration parameters. The second parameter ‘static’indicates that the LS100W will use static IP
address of the third parameter ‘192.168.1.100’. The fifth parameter indicates the subnet mask and the
next indicates the default gateway IP address.
If users want to change only one of the parameters of the group, users can omit trailing parameters
and/or can use ‘*’to keep a parameter value. The screen below will show how to change subnet mask
only without changing IP address and gateway IP address.

18
> set ip static * 255.255.0.0
OK
>Figure 2-9 Changing only one parameter value example
Command usage of ‘set’will differ depending on the groups. Each ‘set’command usage of the group
can be found using ‘help group’command. For example, if users want to know how to use ‘set’
command to configure IP configuration, typing ‘help ip’+ <CR> will show ‘set’command usage for the
IP configuration as shown in Figure 2-10.
> help ip
set ip ipmode par1 par2 ...
- ipmode: static=Static IP / dhcp=DHCP / pppoe=PPPoE
- parameters:
if ipmode = static,
par1 = IP address,
par2 = subnet mask,
par3 = gateway
if ipmode = dhcp,
no parameters required
if ipmode = pppoe,
par1 = PPPoE username,
par2 = PPPoE password
>Figure 2-10 Help screen example
Note:
The changed values will not take effect until ‘save’and ‘reboot’commands are invoked. For more
details, please refer to section 2.4.5 ~ 2.4.7.
2.4.2 ‘get’Command
With ‘get’command, users can view the current parameter values and status of the LS100W. Basic
‘get’command usage is as follows:
get [group] + <CR>
where,
group = 'ip','host','serial' , 'admin' or 'status'
- If group is specified, shows settings of the group.
- If group is omitted, shows settings of all groups.
The group means the category where parameters belong to as like ‘set’command. For example, if
users want to view parameter values related to IP configuration, get command as Figure 2-11
can be used.
