1. Introduction

The LINDY W-LAN 11 (Wireless LAN with 11 Mb/s) offers a quick and reliable solution for
professional wireless networking. It is compliant with standards IEEE802.11b and 802.11.
and is ideally suited for use in historic buildings where no structured cabling can be installed, for
the request of mobile moving network access inside a building, and for free and open network
access (Internet) i.e. in universities, hotels etc.
Connections can be established as peer-to-peer (i.e. notebooks with W-LAN PCMCIA card),
between access points (wireless repeater) or between access point and client (PCMCIA card or
similar). The LINDY Access Point offers a roaming function so that even larger buildings can be
covered by the wireless LAN.
The maximum transmission distance between two points largely depends on the local
environment, building construction and the shielding of walls, ceilings and metal construction
parts of the building. Under ideal conditions the transmission covers a range up to 45m, in most
cases the distance is between 15 and 25m. In the free environment without reflections a
distance of 250m may possibly be achieved.

Please note:

a) A wireless LAN can easily be accessed from unauthorised persons. Only when

encryption is activated is there relative security against this!

b) Without activated Access Control and without password every user with wireless

LAN IEEE802.11 compatible hardware can log into the wireless LAN!

Please refer to the detailed description given later in this Manual.

Wireless Infrastructure

In a wireless infrastructure, the W-LAN 11 acts as a bridge. The Access Point connects the
wireless clients together and acts as a central point for all wireless communications. This would
increase efficiency of the communications since the wireless adapters do not need to be within
direct range of each other.

2. Hardware Installation

Before you begin make sure that the following items are enclosed:

w

The LINDY W-LAN 11 Access Point

w

The power adaptor

w

The Installation disk or CD

If anything is missing or damaged please contact your dealer.

Placement of the Access Point

Before installation determine the best locati on for the AP. The location should be central,
relative to the area being covered by the W-LAN. It should be located some distance from any
highly shielding elements of the building. The AP can either be placed on a flat surface or
mounted vertically on a wall.

Connections

Connect the MDI port of the AP to your Ethernet hub or connect the MDI-X port to a computer
or workstation using straight through STP/UTP cable. Connect the power adaptor to the AP and
to the mains supply.

English Short Manual

Rear view of your W-LAN 11 Access Point:

Power: Connect the power adaptor here.
MDI: RJ-45 connector for Ethernet Hub with10BaseT or 100BaseTX.
MDI-X RJ-45 connector to connect a computer or workstation, you can only use one of

RS-232 Console port to configure and program the Access Point
LED’s status display for the wired Ethernet

After correct installation of all connections to the wired LAN the Link LED should always light
green when the hub or the workstation/computer is switches on.

3. Configuration / Installation

The Access Point provides a user friendly configuration utility (Access Point Manager). It is
delivered ready for use with factory default settings for use with standard W-LAN conditions.
Any configuration changes may be made using the Access Point Manager software, by web
browser administration or by console set-up using either the RS-232 console administration or
direct Ethernet Telnet connection.

English Short Manual

3.1. Access Point Manager Configuration Utility

The Windows based configuration
program; Access Point Manager
provides easy monitoring, checking and
changing of the Access Point parameters.

Place the enclosed CD or Floppy disk into
the computer you want to use to connect
to the AP. Start the set-up program
setup.exe from the enclosed CD or
diskette and follow the instructions given
there. When finished start the program
Access Point Manager. It will
automatically search and detect all LINDY
Access Points in your network

Double click to any Access Point
Symbol to view or change the
settings of the AP selected. The
Default Password as supplied is
“default”

After having entered the correct password the
program will display the MAC address, the
frequency domain (dependent on the
regulations of the countries where used), the
firmware version, connection statistics, the
upgrade utility page, security, access and
encryption settings, etc.

(For further details on Statistics please refer
to the extensive English reference manual)

If you want to set up a wireless LAN with more
then 1 Access Point and you are not familiar
with the basic knowledge for this kind of
WLAN, please contact your local dealer or the
LINDY support department.

are installing. If this WLAN is to be accessed
by all possible/potential clients then use the
setting ‘Use Non-Specifi ed ESSID: non­speci’, resp ectively the ESSID name "ANY".
If you want to secure your WLAN against
unintentional access you should give a
specified ESSID name to all of the clients
that are able to join your WLAN.

1. Einleitung

Das LINDY W-LAN 11 (Wireless LAN mit 11 Mb/s) bietet eine schnelle und zuverlässige Lösung
für kabellosen Netzwerkzugriff. Es ist kompatibel zum W-LAN Standard IEEE802.11b und

802.11.
Es ist prädestiniert für den Einsatz in historischen Gebäuden, in denen kein Kabelnetzwerke
verlegt werden können, für die Anforderung mobile Einsatzorte innerhalb eines Gebäudes oder
um einen allgemeinen freien Netzwerkzugang (z.B. Internet) in einer gegebenen Umgebung
(Universität, Hotel, etc.) zu schaffen.
Verbindungen können prinzipiell als Peer-to-Peer Verbindung (Ad-Hoc) zwischen zwei
Rechnern mit W-LAN PCMCIA Karte aufgebaut werden, zwischen Access Points (Wi reless
Repeater) oder zwischen Access Point und Clients (Infrastruktur, PCMCIA Karte u.ä.). Der
LINDY Access Point beherrscht die Roaming Funktion, so dass mit mehreren Access Points ein
größeres Gebäude abgedeckt werden kann. Die Reichweite ist sehr stark von den
Gebäudegegebenheiten (Abschirmung durch Wände, Träger, etc.) abhängig und kann unter
idealen Bedingungen bis 45m reichen, im allgemeinen liegt die maximale Reichweite bei 15­25m.
Im Freien kann (ohne besondere Antennen) eine Reichweite von ca. 250m erreicht werden.

Bitte beachten Sie, dass

c) ein W-LAN leicht abgehört werden kann und nur mit aktivierter Verschlüsselung

(WEP) ein gewisses Maß an Sicherheit besteht !

d) ohne aktivierte Zugangsbeschränkung und ohne aktiviertes Passwort sich jeder

Nutzer mit IEEE802.11b W-LAN Karte in das Netzt einloggen kann !

Bitte beachten Sie die Aktivierungshinweise zu di esen Themen weiter hinten im Handbuch.

Kabellose Infrastruktur

In einer kabellosen Infrastruktur fungiert das W-LAN 11 als Bridge. Der Access Point verbindet
die kabellosen Clients untereinander und agiert als Schaltzentrale für jegliche kabellose
Kommunikation. Er sorgt somit für effiziente Verbindungen, da die einzelnen Clients sich
untereinander auch außerhalb ihrer direkten Verbindungsreichweite befinden können.

2. Installation der Hardware

Bevor Sie mit der Installation beginnen, stellen Sie bitte sicher, dass Sie die folgenden Dinge
mit der Lieferung erhalten haben:

w

Den LINDY W-LAN 11 Access Point

w

Das Netzteil

w

Die Installati onsdiskette oder –CD

Sollte eines der genannten Teile fehlen, wenden Sie sich bitte an Ihren Fachhändler.

Aufstellung

Der Aufstellungsort für den Access Point sollte möglichst zentral im abzudeckenden
Funkbereich liegen, möglichst mit Abstand zu stark abschirmenden Gebäudeteilen. Der AP
kann aufgestellt oder aufgehängt werden.

Anschluss

Verbinden Sie dem MDI Port mit einem Hub bzw. den MDI-X Port mit einem Rechner bzw. einer
Workstation. Verbinden Sie das Netzteil mit Access Point und Steckdose.
