Kurzanleitung
Installation & Betrieb
EIGENSCHAFTEN
Der LINDY CPU Switch SMART DVI ist für den Betrieb mit PCs mit DVI-D Monitor-
anschluss konzipiert. Der DVI-D Anschluss ist der moderne Digitalanschluss für
Flachbildschirme. Der LINDY CPU Switch SMART DVI unterstützt die analogen
Signalleitungen, wie im DVI-I Anschluss spezifiziert, NICHT.
Er unterstützt digitale Monitorauflösungen bis 1600x1200 bis 60Hz (zur Zeit ist dies die
höchste spezifizierten Auflösungen für DVI-D Single Link, Stand 03/2002) sowie DDC
Monitorerkennung.
Der LINDY CPU Switch benötigt bei Kabellängen unter 5m kein Netzteil. Werden größere
Kabellängen benötigt, so sollte ein optional erhältliches Netzteil verwendet werden; hiermit
können in den meisten Fällen auch noch Kabellängen bis 7,5m realisiert werden. Beachten
Sie bitte, dass für DVI Monitore und Kabel eine Maximallänge von 7,5m genannt wird!
Je nach Hardwarekombination können diese Distanzen im Einzelfall auch größer sein, in
Einzelfällen konnten 12m realisiert werden. Ebenfalls kann die erreichbare Auflösung von
der Kabellänge abhängen, z.B. 1280x1024 ab 5m und nur noch 1024x768 bei 10m. Dies
alles sehr stark von der verwendeten Hardware abhängig.
Der LINDY CPU Switch emuliert für alle angeschlossenen Rechner permanent Monitor,
Maus und Tastatur. Dies sorgt dafür, dass zwischen den angeschlossenen Rechnern
beliebig oft hin und her geschaltet werden kann, ohne dass die Rechner das Maus- bzw.
Tastatursignal verlieren und neu gebootet werden müssen.
KURZANLEITUNG INSTALLATION
Schalten Sie alle anzuschliessenden Computer aus und schliessen Sie sie an die
ORANGEFARBENEN Ports auf der Rückseite des CPU Switch SMART DVI an.
Der Rechneranschluss erfolgt über Standardkabel (LINDY Art.Nr.n in Klammern):
PS/2 (Maus, Tastatur): 1m (33265), 2m (33266), 3m (33267) , 5m (33268) , 10m (33270)
DVI-D (Monitor): 2m (41240), 3m (41241), 5m (41242) , 7,5m (41244) , [10m*s.o. (41243)]
Serielle PC-Mausanschlüsse (COM-Port, Sub-D-9) werden nur mit dem korrekten
Mausadpter (z.B. LINDY Art.Nr. 70058) unterstützt (nähere Angaben im ausführlichen
englischen Handbuch).
Schließen Sie Ihre Tastatur, Monitor und Maus an den GRAUEN Ports auf der Rückseite
des CPU Switch SMART an.

ZUSAMMENFASSUNG DES HANDBUCHES
Verschiedene DVI Grafikkarten müssen über die DVI Hot Plug Detect Funktion und
die DDC Monitorerkennung erst den DVI Monitor erkennen, bevor sie ein Bildsignal
an den Monitor senden (dürfen). Dies geschieht in der Regel in den ersten 5
Sekunden des Bootvorganges. Die Grafikkarte kann nur mit dem Monitor kom-
munizieren, wenn der entsprechende Computer aktuell als der Aktive selektiert ist!
Um diesen Vorgang und das Booten möglichst einfach zu gestalten, schaltet der
CPU Switch SMART DVI automatisch auf den Kanel / den Computer, der gerade
gebootet wird. Wenn mehrere Computer gebootet werden sollen, muss dies daher
der Reihe nach mit kurzer Wartezeit geschehen!
Die Voreinstellungen (Defaultkonfiguration) des CPU Switch SMART ist für die meisten
Einsatzzwecke geeignet. Der CPU Switch SMART DVI kann über die angeschlossenen
Rechner mit Strom versorgt werden. Beim Anschluss mehrerer Rechner wird die
Stromentnahme auf alle Rechner verteilt, so dass auch das Abschalten einzelner Rechner
kein Problem darstellt.
Der Computer, auf dem gearbeitet werden soll, kann auf verschiedene Arten ausgewählt
werden: entweder durch Drücken der Kanalwahltaste auf der Frontblende, durch Drücken
einer Hotkey-Tastenkombination auf der Tastatur oder durch eine 3-Tasten-Maus.
Um einen Computer per Tastatur-Hotkey auszuwählen werden die Strg und ALT Tasten
sowie die erforderliche Port-Taste (z.B. 1 ) gleichzeitig gedrückt.
Zum Umschalten zwischen den angeschlossenen Rechnern mit der Maus müssen die
mittlere Taste der Maus und gleichzeitig die linke oder rechte Taste kurz gedrückt werden.
Der LINDY CPU Switch SMART DVI bietet die Möglichkeit, viele integrierte Optionen wie
Umschalt-Hotkey, Bildschirmschoner, Passwort, AutoScan-Modus weitgehend zu
konfigurieren. Informationen hierzu finden Sie im ausführlichen englischen Handbuch.

2. Installation
2.1 What you will need
Cables to connect the CPU Switch Smart DVI to each of your PC keyboard, video
and mouse ports. Cable specifications are given in appendix A. (You do not need to
connect a mouse cable if you are not using the mouse).
A monitor with a DVI-D connector that will work when connected directly to each
of your PCs. The CPU Switch Smart DVI supports (single-link) DVI-D compatible
Flat Panel displays and monitors.
A computer fitted with a DVI graphics card and DVI-D connector.
A standard AT or PS/2 style keyboard. If you are using an AT keyboard with a 5
pin connector you may connect this to the CPU Switch Smart DVI using a standard
AT to PS/2 keyboard adapter.
A PS/2 style two or three button Microsoft or Logitech compatible mouse or a
Microsoft IntelliMouse / IntelliMouse Explorer compatible mouse. If you wish to use
the mouse to switch the CPU Switch Smart DVI's channel then you will need a three
button mouse or an IntelliMouse.
(The CPU Switch Smart DVI supports ‘Internet Mice’ that are compatible with the
Microsoft IntelliMouse. These are fitted with a wheel or other scroll control and
sometimes have additional buttons. Examples are: Microsoft IntelliMouse, Logitech
Pilot Mouse+, Logitech MouseMan+, Genius NetMouse and Genius NetMouse Pro.)
A suitable mouse driver for your PCs. Supported types are:
- PS/2 or RS232 two button mouse driver (any manufacturer).
- Microsoft mouse driver (including IntelliMouse).
- Logitech mouse driver (including two button, three button and wheel mouse)
Use of PS/2 and RS232 style mice with the CPU Switch Smart DVI - All of the
mouse connections from CPU Switch Smart DVI to PCs support either a PS/2 or an
RS232 mouse. CPU Switch Smart DVI automatically converts from the PS/2 mouse
commands to RS232 serial mouse commands. Serial mice types are selected by

CPU Switch Smart DVI Installation and Use Page 10
using an adapter as described in Appendix A. The CPU Switch Smart DVI will
operate without a mouse connected if you do not wish to use one.
2.2 Mounting the CPU Switch Smart DVI
The CPU Switch Smart DVI has been designed for use on a desktop or shelf in
close proximity to the user’s monitor and peripherals. The optional remote controller
may be used if you wish to locate the CPU Switch Smart DVI on a desk or shelf that
is some distance from the monitor and peripherals.
2.3 Connecting your devices
Ensure that the optional power adapter is disconnected from the CPU Switch Smart
DVI and that all the devices which are to be attached are switched off. Connect the
shared keyboard, PS/2 mouse and monitor to the connectors at the rear of the CPU
Switch Smart DVI (see figs 1, 2 and 3). Next, connect each computer system unit in
turn with the keyboard cable, mouse cable and video cable. Any unused computer
connections can be left unconnected. To connect computers with serial mouse
connections and AT style keyboard connections use the adapters specified in
appendix A. If you have an existing 6-pin mini-DIN to 9-pin serial adapter that came
with a mouse it may not be suitable for use with the CPU Switch Smart as there are
several different standard wiring configurations for these adapters.
The CPU Switch Smart DVI is now ready for use and will start to operate as soon as
one of the attached PCs is powered on. If you are connecting to PCs using cables
that are longer than 5 metres or are cascading the CPU Switch Smart DVI to
another CPU Switch Smart DVI you will need to use the optional power adapter.
When using the optional power adapter, ensure that it is connected to the mains and
powering the CPU Switch Smart DVI before you switch on the connected computers.

CPU Switch Smart DVI Installation and Use Page 11
Failure to switch the CPU Switch Smart DVI and computers on in the correct order
can lead to the mouse and/or keyboard not being recognised by the computers
when they are switched on.
2.4 ‘Interface powered’ operation without the optional power
adapter
The CPU Switch Smart DVI draws its power from the connected computers via the
keyboard cables. A single keyboard connection is normally sufficient to power the
CPU Switch Smart DVI provided that the cable is no longer than 5 metres. If more
than one computer is connected then the power will be intelligently drawn from all
computers. Cables longer than 5 metres may be used provided that the CPU Switch
Smart DVI is already powered by another connected computer or the optional power
adapter. If you are cascading the CPU Switch Smart DVI to another CPU Switch
Smart DVI then a power adapter must be connected to all CPU Switch Smart DVIs.
2.5 Configuring your PCs
Configure your PC in the same way that you would if your keyboard, mouse and
monitor were all connected directly to your PC. CPU Switch Smart DVI emulates
Microsoft compatible serial, IntelliMouse, IntelliMouse Explorer and PS/2 mice, so
ensure that your PC software is configured for a Microsoft mouse of the correct type.
Refer to the list of supported drivers in section 2.1.

CPU Switch Smart DVI Installation and Use Page 12
2.6 Configuring the CPU Switch Smart DVI
IMPORTANT NOTE
Some DVI video cards need to communicate with a monitor before they will
output a video signal. This communication normally occurs within the first 5
seconds after the computer has been powered on. The computer can only
communicate with the monitor if it is the currently selected computer. If you
have this type of DVI video card you will need to select the computer before
switching the computer on. To make this process easy for you we have built
an auto-switch function into the CPU Switch Smart DVI. With the auto-switch
function enabled the CPU Switch Smart will automatically switch to a
computer when the computer is powered on. When powering on several
computers you should power them on in sequence, waiting a few seconds
between each one to allow the video card to communicate with the monitor.
•To enable the auto-scan function move switch 1 on the underside of the
CPU Switch Smart DVI to the ON position.
•To disable the auto-scan function move switch 1 on the underside of the
CPU Switch Smart DVI to the OFF position.
The CPU Switch Smart DVI is supplied pre-configured with factory defaults which
are suitable for most applications. There are a number of more advanced options
which can be set by the user. These are stored in the CPU Switch Smart DVI's
EEPROM memory and are retained when the power is disconnected.
The options may be changed whilst the CPU Switch Smart DVI is in configure mode.
You may enter configure mode at initial power on or whilst the CPU Switch Smart
DVI is running:
To enter configure mode at power on:
Switch off all the attached PCs and the CPU Switch Smart DVI. Hold down the front
panel key whilst powering on the CPU Switch Smart DVI. Remember that the CPU
Switch Smart DVI draws its power from any attached PC via the keyboard cable and
so will power itself on when the attached PC is switched on or when the optional
power adapter is connected. Do not release the key until the CPU Switch Smart DVI
displays 'C' to show that it has entered configure mode.

CPU Switch Smart DVI Installation and Use Page 13
To enter configure mode whilst the CPU Switch Smart DVI is running:
Hold down the front panel key for 5 seconds until the front panel display shows ‘C’.
In configure mode, options are entered by typing a letter followed by a number
followed by (return). Use ESC to abort the entry of an option. The CPU Switch Smart
DVI will remain in configure mode until you type 'E' (return).
For example: to set hotkey option 2 type the following at the 'C' prompt
(at CPU Switch Smart DVI 'C' prompt) HH 22 ff
