GENERAL
n Wireless access point
[Infrastructure mode]
Ex.: Adhoc mode
There are two communication modes for
wireless LAN: adhoc mode and infrastructure mode. The adhoc mode means
that the network consists of wireless
SL-1105
LAN terminals only. This mode allows
pear-to-pear communications among
computers that are equipped with ICOM
SL-11
SL-11
wireless LAN card (See the figure shown
to the right).
The other mode, infrastructure mode,
uses a repeater called the access point
such as AP-12.
The infrastructure mode allows wireless LAN terminals to communicate with each other
via the access point, or with wired LAN terminals via access point at which Ethernet
connection is made. (See the figure shown below).
In this mode, a router connected to the wired LAN permits wireless LAN terminals to
have access to the Internet.
* Up to 256 wireless terminals can be connected through the AP-12.

[Multi-channel roaming function]
Connecting two or more access points to a wired LAN allows the most suitable access
point to be automatically selected depending on the radio communication conditions
when the wireless terminal is moving.
This function will enable you to have access to the network while you are moving in a
wide area, for example, in a large factory or warehouse.

l Setting the IP address and subnet mask
This tab is used to set the IP address and subnet mask so as to allow the product
to be connected to a working network.
IP address: Specify the IP address of the product in this field. (Default: 192.168.0.1)
Subnet mask: Specify the subnet mask in this field. (Default: 255.255.255.0)
[Note]
* The AP-12 cannot be used as a DHCP server. This means the IP address and the
subnet mask of the product must be set manually. The IP address of terminals may be
assigned automatically depending on the network environment. (See the setting
examples shown below).
* The IP address for each computer within a network group must be unique.
* The subnet masks of all the computers within a network group must be the same.
(IP Address setting examples)
The following shows addressing examples where the network comprises three
computers.
AP-12: 192.168.0.40*1 (subnet mask: 255.255.255.0)
Wireless terminal A: 192.168.0.41*2 (subnet mask: 255.255.255.0)
Wireless terminal B: 192.168.0.42*2 (subnet mask: 255.255.255.0)
Wireless terminal C: 192.168.0.43*2 (subnet mask: 255.255.255.0)
*1: In case a DHCP server automatically assigns IP addresses to other access points, it
is recommended to specify the IP address of the product as large as practicable in
order to avoid address collision.
*2: If the network contains a DHCP server (such as dialup router) that is capable of
automatically assigning IP addresses, the server capability may be utilized to assign
IP addresses to wireless terminals. In this case, “Obtain an IP address automatically”
is selected during computer setup for networking.
** For details on network settings, see the instruction manuals for the DHCP server

command:
“ping xxx.xxx.xxx.xxx”
where “ xxx.xxx.xxx.xxx” is the IP address of the AP-12.
By executing the ping command, four pings (echo requests) are transmitted and a reply
message should be received for each ping.
If a reply is not received, check the protocol settings of the station, as well as the settings
of the respective wireless LAN cards (Network Mode, ESS ID, etc.).
The message “destination unreachable” will be displayed if the IP address and subnet
mask of the source and destination stations are not set correctly.

TERMINOLOGY
DHCP server
DHCP (Dynamic Host Configuration Protocol) is a
protocol that allows a client in a TCP/IP network
to automatically obtain required information from
a server.
The DHCP server manages such network
information as the IP Address, Default Gateway,
and Domain Name.
ICOM DR-1WL or other devices with DHCP
server capability allocate an IP address, default
gateway, DNS address, etc., to the DHCP clients
(computers) when the DHCP clients start up.
LAN (Local Area Network)
A network that is relatively small in scale. A
typical LAN occupies a single office or a single
floor of a building.
ESS ID (Extended Service Set-IDentifier)
An ESS ID is a name used for identification when
multiple network groups are formed within the
transmission area of a wireless network. The ESS
IDs of the wireless terminals in a wireless network
group communicating with the AP-12 are set to
the same value as the ESS ID of the AP-12.
TCP/IP
TCP/IP is the basic protocol of the Internet and is
currently the most popular protocol in the world. It
is supported by Windows 95/98, Windows NT,
and the other major operating systems.
SMTP and FTP use this protocol.
A TCP/IP control panel is a standard item in
Macintosh computers provided with Open Transport.
Ethernet
Ethernet is a set of standards and protocols for
LAN communications developed by Xerox, Digital
Equipment Corporation, and Intel. Types of Ethernet include 10BASE-T, 10BASE-5, and 10BASE2, each requiring a different cable specification.
IP (Internet Protocol) address
The IP address is a 32-bit address used to
distinguish the devices in a network constructed
using TCP/IP protocol. Each network device has
a unique IP address.
The IP address is usually expressed as a base-10
numeral string made up of four 8-bit sections.
(Example: 192.168.0.1)
A private IP address is an IP address set
independently by the network administrator.
It is not necessary to petition an address management institution or a provider, but a private IP
address must be allocated according to the
following rule:
When connecting with an external network, the
private address must be converted into a global
IP address.
The following IP addresses can be used freely as
private IP addresses:
Class A:
10.0.0.0 to 10.255.255.255
Class B:
172.16.0.0 to 172.31.255.255
Class C:
192.168.0.0 to 192.168.255.255

MAC address (Media Access Control Address)
A MAC address is a physical address (number)
uniquely set into each wired or wireless LAN card.
LAN card manufacturers manage MAC addresses
so that no two LAN cards in the world have the
same MAC address.Ethernet uses the MAC
address to send and receive frames.
URL (Uniform Resource Locator)
URLs are used to access home pages and other
sites on the Internet.
Our URL is http://www.icom.co.jp.
Web browser
A web browser is a software application used for
searching web servers and viewing web pages.
Common applications include Internet Explorer
and Netscape Navigator.
10BASE-T
10BASE-T is a connection scheme for Ethernet
configurations using twisted pair cable.
The “10” in 10BASE-T represents an Ethernet
transmission speed of 10 Mbps and the “T”
represents twisted pair cable.

TERMINOLOGY
Access point
An access point is any device used to connect a
wired LAN to a wireless LAN.
Client
A client is any terminal or application in a network
that requests information or a service from a
server and receives the corresponding response.
Global IP address
A global address is a globally unique address that
held by only one device on the entire internet.
Subnet mask
A subnet mask is used to allow on IP address
represent both the network address and the host
address.
Assuming the IP address of a certain host is
192.168.0.1 and the subnet mask is 255.255.255.0,
if the IP address and subnet mask are multiplied
as binary numbers the network address will be
192.168.0.0 and the remaining 1 will be the host
address.

Hub
A hub is required when the AP-12 and other
devices are used construct a network. The hub is
connected to the AP-3 using 10BASE-T cable.
Flash memory
The flash memory is a memory device in the AP12 to which data can be written.
Information stored in the flash memory is not
erased when the power to the AP-12 is turned off.
Protocol
A protocol is a defined set of steps that is
followed when data is sent and received.
Traffic
Traffic refers to the flow of packets over a network
or the load (amount of data) born by the network
circuits.
When the traffic is high, data transfers may be
delayed and data may be lost.
Network
An arrangement wherein servers, work stations,
computers, and other devices are connected via
cable or a telephone circuit for the purpose of
exchanging data.
Packet
The unit by which data is sent and received in a
network.
A packet comprises a header portion containing
information required for sending and receiving
and a data portion containing the data being sent.
13
Password
A character string that a user must enter in order
to access a network. The password provides
network security because, once established, the
password must be entered correctly by the user
or access will be denied.
