3-2 Selecting an
Installation
Site
[NOTE]
The transmission range
varies somewhat depending
on the installation location.
Use the line-of-sight distances indicated below as
guidelines when using an
SL-1100 or SL-1105 wireless
LAN card.
Indoors : approx. 50 m
Outdoors : approx. 150 m
When transmission speed is
11 Mbps
Indoors : approx. 30 m
Outdoors : approx. 70 m
The installation site for the wireless access point
must be selected carefully in order to avoid signal
interference and reductions in transmission speed
and range.
Observe the following guidelines when selecting the
location.
● Select a location with as clear a line of sight as possible (i.e., as high as possible).
● Select a stable, level surface that is free of vibrations
and the danger of the unit falling.
● Also observe the following:
• Do not place objects on top of the unit or stack units
on top of one another.
• Radio signals will pass through walls and glass but
not through metal. Concrete walls may be reinforced
with steel or other metal material that will block the
signal.
• The transmission range is widest in an open space.
However, the signal may be reflected from the large
metal walls in such a location as a warehouse.
• Floors generally have steel girders and are installed
with metal fire protection material. Consequently,
communication between different floors is often not

5-2 Setting Tips
● Complete the settings described in this chapter and
shut down the computer before proceeding to Chapter
6 (☞ p. 37).
● Complete the settings described in Chapter 6 (☞ p. 37)
before connecting the AP-3 to a working LAN.
● When constructing a TCP/IP network, it is necessary to
set the IP addresses of the computers that will be connected to the network. (☞ p. 17).
● A computer running Windows will acquire the local IP
address from the AP-3 when Windows is started up
and a computer using a Macintosh operating system
will acquire the local IP address each time network
communications are begun (e.g., when the computer
accesses the internet or email).
Make sure the AP-3 unit is turned on and “Use DHCP
server function” is set to “Yes” on the screen shown on
page 52.
● When the AP-3 unit attempts to allocate a local IP
address to a computer and another computer (nonDHCP client for which local IP address was set manually) is already using the same local IP address, the
AP-3 unit will not detect the existence of the address
used by the other computer.
● When [Routing Mode] (☞ p. 51) is not used, the total
number of IP addresses that the AP-3 unit can allocate
automatically to both wireless and wired LAN computers is a 5 to 128. When [Routing Mode] is used, the AP3 unit can allocate 5 to 128 IP addresses to wireless
LAN computers and the same number to wired LAN
computers. The original factory setting for the number
of allocations is 30 for both wired and wireless LAN.
(☞ p. 53)
Avoid overlapping between the IP addresses of clients
(including clients having a wireless connection) connected to the same network and the range of IP
addresses that the AP-3 unit can automatically allocate
to computers.

WIRELESS FUNCTIONS
The AP-3 unit can function in the following two ways
to construct a wireless network:
• Wireless access point function (☞ section 7-1 below)
• Roaming function for roaming with a wireless terminal
(☞ section 7-2, p. 46)
* When a wireless transmission speed of 11 Mbps is
used, the transmission range is roughly 30 m indoors
and 70 m outdoors (line of sight).
[NOTE]
A Macintosh computer cannot be used as a wireless
terminal.
7-1 Wireless Access Point Function
The wireless access point function refers to using the
AP-3 unit to construct a local area network wherein
wireless terminals can communicate with each other
as well as with wired terminals connected to the AP3 via an Ethernet cable.

7-2 Roaming Function
The roaming function refers to installing multiple AP3 units along an Ethernet LAN so that the wireless
transmission areas overlap. This arrangement allows
wireless terminal to maintain communications with
the Ethernet LAN while moving among the wireless
transmission areas. In short, this function allows the
wireless transmission area to be expanded.

precautions
46
● Overlapping of IP addresses can be avoided by setting
up only one of the AP-3 units so that the DHCP server
function is enabled.
● Within the mobile wireless transmission area (roaming
area), all wireless terminals and AP-3 units for which
the roaming function will be used must use the same
[ESS ID] setting.
Wireless terminals set to a different [ESS ID] will not be
able to communicate with the AP-3 units.
● The wireless LAN terminals, including those in the
roaming area, will operate as part of the same network
group as wired LAN terminals. Therefore, routing mode
(☞ p. 51) cannot be used when the roaming function is
used.
● When SL-1100 or SL-1105 LAN cards are used and
roaming is conducted using the same channel for all
LAN cards, the transmission speed may decline in the
interference areas where the signals from two wireless
access points (i.e., AP-3 units) can be received simultaneously. To avoid interference completely, set the
channels of the AP-3 units at least four channels apart.
● Connect the AP-3 units in a cascade arrangement by
connecting them through a hub using Ethernet cable.

MAINTENANCE
■ Checking the connection with the AP-3
If the IP address of each station (terminal group) is
set correctly, you can easily test whether or not IP
packets are reaching their proper destination by
using the “ping” command.
To conduct the test, open the MS-DOS window and enter
the following command:
ping xxx.xxx.xxx.xxx
where “xxx.xxx.xxx.xxx” is the IP address of the AP3 unit.
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 and the AP-3 unit, 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 station and AP3 unit are not set correctly.

GLOSSARY
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.
The AP-3 is provided with a DHCP server that allocates an IP address, default gateway, DNS
address, etc., to the DHCP clients (computers)
when the DHCP clients start up.
DNS (Domain Name System)
DNS is a name resolution service for TCP/IP networks.
The AP-3 provides a domain name service, in
accordance with DNS, that allows computer
names and domain names to be registered in a
domain name server.
By using the domain name service, the IP address
of the desired site can be designated not as numbers but as easy-to-understand domain names
and host names.
ESS ID
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-3 are set to the
same value as the ESS ID of the AP-3.
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
10BASE-2, 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 manager. 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.
80
The following IP addresses can be used freely as
private IP adresses:
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
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.
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.
RIP (Routing Information Protocol)
RIP is a protocol used in a TCP/IP network to
exchange routing information between routers.
Routers use RIP to send packets to the correct
destination.
SYSLOG
SYSLOG is a function for sending system messages to destinations within a network.
Log information can be managed using a UNIX or
other SYSLOG server if the network supports this
function.
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.
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.
GLOSSARY
10BASE-T and 100BASE-TX
10BASE-T and 100BASE-TX are connection
specifications 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.
Category 5 twisted pair cable supports 100BASETX as well as 10BASE-T.
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.
18
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.
Hub
A hub is required when the AP-3 and other devices
are used construct a network.
The hub is connected to the AP-3 using 10BASET or 100BASE-TX cable.
In order to achieve transmission speeds of 100
Mbps, Category 5 twisted pair cable must be used
and the hub must support 100BASE-TX.
Flash memory
The flash memory is a memory device in the AP-3
to which data can be written. Information stored in
the flash memory is not erased when the power to
the unit 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 send 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.
