Installation & Betrieb

EIGENSCHAFTEN

Der LINDY CPU Switch SMART DVI ist für den Betrieb mit PCs mit DVI-D Monitoranschluss 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 kommunizieren, 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. Weitere Hinweise finden Sie dort auch zu den Themen: Problembehebung Kaskadierung mehrerer CPU Switches Hot-Plugging von Rechnern am CPU Switch Einstellungen für das Mausprotokoll Mouse Recovery nach Verlust des PS/2 Maussignals an einem der angeschlossenen PC Mouse Recovery nach Abziehen der Maus vom CPU Switch Flash-Upgrade der Firmware

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 9

Page 17

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 10

Page 18

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 11

Page 19

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 12

Page 20

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

2.8 Resetting the CPU Switch Smart DVI without disconnecting your devices

The CPU Switch Smart DVI draws its power from the connected computers and therefore may only be fully powered down when all the connected computers have been switched off or disconnected. However, the CPU Switch Smart DVI may be reset without disconnecting or powering down your computers by using the reset switch on the underside of the unit. Performing a reset using this switch performs a complete hardware reset on the CPU Switch Smart DVI and is equivalent to switching off the power. To perform a hardware reset, move option switch 8 to the ON position (halt and reset) and then back to the OFF position (normal operation).

2.9 Other useful installation information

PC boot up sequence - When your PCs are powered on they communicate with

any attached keyboards and mice and setup parameters required by the particular operating system. It is necessary for the CPU Switch Smart DVI to be attached and powered on during this sequence so that it can give the required responses and keep track of all the modes and settings requested by each of the connected PCs.

Mouse characteristics - do not unplug a PS/2 mouse connection from a PC whilst the PC is on. Due to the design of PS/2 mice communications the mouse function on the PC will be lost and you will have to re-boot the PC to regain normal operation.

CPU Switch Smart DVI Installation and Use Page 15

Page 23

Unplugging the mouse from the CPU Switch Smart DVI will also cause it to stop operating when it is plugged back in. RS232 mice can usually be unplugged and plugged back in provided that a mouse was connected when the operating system initially booted. The CPU Switch Smart DVI is fitted with a PS/2 mouse recovery system which allows you to disconnect and re-connect the shared mouse without powering down the system (although this is generally not advisable) - see section

2.10 for details.

Keyboard and mouse mode switching - The CPU Switch Smart DVI keeps a log of the keyboard and mouse mode and resolution settings requested by each of the connected PCs. These settings are automatically restored to the shared keyboard and mouse when the CPU Switch Smart DVI channel is switched thus ensuring maximum software compatibility. The keyboard num, caps and scroll lock states are an obvious example of this process.

2.10 Re-enabling a disconnected PS/2 mouse

If you disconnect the shared PS/2 mouse from the CPU Switch Smart DVI by accident during operation then the mouse operation will be lost when the mouse is plugged back in. To avoid having to reboot the entire system in this situation the CPU Switch Smart DVI is fitted with an automatic mouse recovery system.

With the PS/2 mouse disconnected, change the channel using the keypad or keyboard hotkeys. The CPU Switch Smart DVI detects that the mouse has been disconnected and triggers the automatic recovery system. Plug in the PS/2 mouse and the CPU Switch Smart DVI will re-initialise it.

Alternatively you can reset the keyboards and mice by holding down the front panel key for 5 seconds. When the character ‘C’ is displayed on the front of the CPU Switch Smart DVI, press the front panel key again. A complete power off reset of the connected keyboards and mice will then be performed. This function only resets the shared keyboard and mice that are plugged into the control port. It does not affect the status of any of the other ports on the switch or the CPU connections.

CPU Switch Smart DVI Installation and Use Page 16

Page 24

2.11 Hot plugging the CPU Switch Smart DVI into running systems and re-enabling disconnected CPU PS/2 mouse connections

It is advisable to switch off the systems that are going to be connected to the CPU Switch Smart DVI before installation. However, if this is not possible then most systems can be hot plugged by using the CPU Switch Smart DVI’s mouse restoration functions. The keyboard connection will normally restore itself automatically.

On many PCs, mouse movement will be lost if the PS/2 mouse is unplugged and plugged back in whilst the PC is running. Mouse movement can then only be restored by rebooting the PC. This is because the mouse drivers only setup and enable the mouse when the PC is initially booted.

If you have switched off your CPU Switch Smart DVI or you are attempting to ‘hot plug’ it into a system that is already running, you may be able to restore lost mouse movement using the CPU Switch Smart DVI's mouse restoration functions.

Mouse restoration functions should be used with care as unpredictable results may occur if the wrong mouse type is selected. If in doubt restore the mouse by powering down the PC normally.

Standard PS/2 mouse data uses a different data format to IntelliMouse data and so two reset functions are provided on the CPU Switch Smart DVI. The type of data format expected by the PC depends upon the driver and the type of mouse that was connected when the driver was booted. The following table may be used as a guide. Note that the mouse reset functions predict the likely mouse resolution settings but may not restore the speed or sensitivity of the mouse exactly as they were when the PC originally booted.

Type of mouse / system Driver type Likely expected Suggested Connected at bootup data format restoration

2.12 Upgrading the CPU Switch Smart's flash memory

The CPU Switch Smart DVI uses flash memory technology which enables the firmware code to be upgraded by the user. Upgrades are performed by connecting a PC's serial port to the CPU Switch Smart's options port and running an upgrade program on the PC. This upgrade program downloads the new firmware to the CPU Switch Smart and checks that the data has been programmed correctly.

To perform a firmware upgrade on your CPU Switch Smart DVI you will need a suitable serial upgrade cable and an IBM PC compatible computer with an RS232 serial port and an operating system that supports DOS. Upgrade cables may be purchased for LINDY or may be made using the wiring specification given in Appendix A4. You will also need to download the latest version of the CPU Switch Smart DVI firmware which is available free of charge at www.LINDY.com.

CPU Switch Smart DVI Installation and Use Page 18

Page 26

To perform a flash upgrade on the CPU Switch Smart DVI:

Step 1 - Connect your computer to the CPU Switch Smart

Connect your computer's serial port to the CPU Switch Smart DVI's options port (labelled OPTIONS/FLASH).

Step 2 - Select flash upgrade mode using option switch 7

Move option switch 7 on the underside of the CPU Switch Smart DVI to the ON position.

Step 3 - Reset the CPU Switch Smart DVI

Reset the CPU Switch Smart DVI by moving option switch 8 to the ON position (halt and reset) and then back to the OFF position (normal operation). Alternatively you may reset the CPU Switch Smart by powering off all the attached computers and removing the optional power adapter.

Step 4 - Ensure that the CPU Switch Smart is powered on

Ensure that the CPU Switch Smart is powered on. It is normally possible to upgrade the CPU Switch Smart when it is powered from a single computer, however it is good practice to ensure that there is the maximum possible power availability during flash upgrades and so if possible ensure that all the computers are powered on. The upgrade program monitors the CPU Switch Smart's voltage and will not allow an upgrade to be performed if the voltage is insufficient.

The display should now show:

Step 5 - Run the upgrade program

The latest version of the CPU Switch Smart DVI firmware is available from the LINDY website at www.LINDY.com. The program and data files are supplied as a pair e.g.

AVG129.EXE AVG129.HEX

CPU Switch Smart DVI Installation and Use Page 19

Page 27

and should be downloaded to the same directory on your PC. Run the file AVGxxx.EXE (e.g. AVG129.EXE) and follow the on-screen instructions. During the upgrade the display will show an upper case U and the dot will flash to show that the upgrade is in progress.

The display will again show a lower case U when the download is complete. Move option switch 7 to the OFF position to exit upgrade mode and start normal operation. You may check the new firmware version by entering configure mode and using the firmware version query function.

Some useful issues to bear in mind when performing flash upgrades

The upgrade program rewrites the CPU Switch Smart's firmware code. If the upgrade process is interrupted then the CPU Switch Smart will have invalid code and will not be able to operate. It is therefore good practice to ensure that the upgrade process is always fully completed. A partial or failed upgrade may be rectified by performing another upgrade. If the upgrade process is interrupted accidentally then you should immediately repeat the upgrade process without moving switch 7 from the flash upgrade (ON) position. Switch 7 forces the CPU Switch Smart into flash upgrade mode and prevents the upgraded code from being run. Running faulty or partially upgraded code may have unpredictable results and may damage your CPU Switch Smart or computing equipment. For obvious reasons, the code that the CPU Switch Smart uses to perform upgrades is not itself upgradeable - a common problem on some flash upgradeable products that could effectively be destroyed by a partial upgrade!

WARNING - Running faulty or partially upgraded code may have unpredictable results and may damage your CPU Switch Smart or computing equipment.

3. Using the CPU Switch Smart DVI

This section explains the general operation of the CPU Switch Smart DVI. We recommend that you read this section before starting to use the product.

IMPORTANT NOTE

• 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.

3.1 Power on status

At power on the CPU Switch Smart DVI selects computer 1 and displays '1'. If a password has been set then ‘P’ will be displayed and the CPU Switch Smart DVI will remain locked until a valid password is entered.

CPU Switch Smart DVI Installation and Use Page 21

Page 29

3.2 Front panel key and remote controller

The front panel key is used to select which channel is currently controlled by the shared keyboard, mouse and monitor ports. Pressing the key during normal operation will cause the next channel to be selected.

The key can also be used to access the CPU Switch Smart DVI’s configuration mode (see section 2.6). To do this press the key and hold it down for 5 seconds until ‘C’ appears on the CPU Switch Smart DVI’s front panel display.

An optional remote controller is also available which replicates the front panel key and display, but can be located remotely from the CPU Switch Smart DVI. This is particularly useful in applications where the CPU Switch Smart DVI is located away from the desktop. The remote controller can be conveniently attached to your keyboard with a couple of Velcro strips to give instant channel information and key control.

3.3 Status display

The status display usually shows the currently selected port. If autoscan mode is selected, the segments will illuminate in sequence in a clockwise direction interspersed with a display of the currently selected channel. If CPU Switch Smart DVI has been locked, ‘P’ will be displayed until a valid password has been typed to unlock the unit. Data flow from the mouse or keyboard causes the dot to flash.

CPU Switch Smart DVI Installation and Use Page 22

Page 30

CPU Switch Smart DVI Installation and Use Page 23

Page 31

3.4 Keyboard hotkey control

CPU Switch Smart DVI can be conveniently controlled by selecting channel, autoscan mode or security locking from the keyboard. All of the hotkey control commands are invoked by holding down the two hotkeys and then pressing a command key. By default, the two hotkeys are ‘CTRL’ and ‘ALT’, although other combinations can be selected by reconfiguring the hotkeys (see section 4.4). Once the hotkey command has been activated you will need to release the hotkeys and the command key before a new hotkey command is accepted by the CPU Switch Smart DVI. HOTKEYs + TAB is an exception and this allows you to 'tab through' the ports by holding down the hotkeys and repeatedly pressing TAB. The hotkey command are summarised below (note that the numbers on the numeric keypad do not form part of a valid hotkey) :

‘HOTKEYs’ and ‘1’ - selects channel 1 ‘HOTKEYs’ and ‘2’ - selects channel 2 ‘HOTKEYs’ and ‘3’ - selects channel 3 ‘HOTKEYs’ and ‘4’ - selects channel 4

‘HOTKEYs’ and ‘TAB’ - selects the next channel

‘HOTKEYs’ and ‘A’ - selects autoscan mode where each channel is displayed for

the selected time (see section 4.2). To cancel autoscan mode simply select any fixed channel either by hotkey or using the CPU Switch Smart DVI button.

‘HOTKEYs’ and ‘0’ – switches off the video signal and displays 0. This will cause some monitors to go into standby mode or switch off. The video signal can be reenabled by selecting a channel.

‘HOTKEYs’ and ‘L’ - disables the CPU Switch Smart DVI's keyboard and mouse and displays 0. The video signal is switched off. If a password has not been set then the CPU Switch Smart DVI can be re-enabled by selecting a channel. If a password has been set then the CPU Switch Smart DVI displays 'P' to indicate that a valid password must be entered to unlock the switch. Simply type the same key combination as was set during configuration (see section 4.7) followed by the (return) key. Note - if anyone has typed at the keyboard whilst in secure mode, it will be necessary to type (return) first to clear the invalid password, then type the valid password followed by (return) again.

Examples of common hotkey sequences (assuming CTRL + ALT hotkey option):

3.5 Mouse control

Computers may conveniently be selected using a three button mouse. In order to switch to the next computer simply hold down the central mouse button (the wheel mouse button on an IntelliMouse) and click on the left hand mouse button to select the next computer or the right hand mouse button to select the previous computer. If the CPU Switch Smart has been set to scan active ports then the next or previous active channel will be selected. If it has been set to scan all ports then the next or

CPU Switch Smart DVI Installation and Use Page 25

Page 33

3.6 RS232 control

CPU Switch Smart DVI can be controlled by a remote RS232 device. To select a channel the data rate of the sending device must be set to 1200 baud, 8 bits, no parity and 1 stop bit. No handshaking is used by the CPU Switch Smart DVI. Simply send the character for the channel which needs to be selected, for example ASCII ‘1’ (hex code 31) will select channel 1, ASCII ‘2’ (hex code 32) will select channel 2 and so on. The CPU Switch Smart will echo the ASCII character back to the sending device when the channel has been changed. The serial interface pins are found on the options connector on the rear of the CPU Switch Smart. Pin assignments for this connector are given in appendix A.

3.7 Cascading CPU Switch Smart DVIs

CPU Switch Smart DVI switches can be connected together to expand the number of connected computers. When cascading CPU Switch Smart DVIs a power adapter (see section 1.2) must be connected to each CPU Switch Smart DVI. CPU Switch Smart DVIs can be connected in a cascaded tree structure. This can be particularly useful where clusters of computers are located some distance from each other because each unit acts as data booster and can each be up to 5 metres away from the next CPU Switch Smart DVI. The channel can be selected on remote CPU Switch Smart DVI units using an extension of the HOTKEY control .

For example, consider a situation where two CPU Switch Smart DVI units are connected together as shown below. To connect to the computer attached to port 3 on CPU Switch Smart DVI B the user would hold down the hotkey keys then press ‘2’ followed by ‘3’, whilst keeping the hotkey keys pressed. This will have the effect of connecting to port ‘3’ of the CPU Switch Smart DVI which is connected into port ‘2’ of the first CPU Switch Smart DVI unit A.

For example to connect to port 3 on the CPU Switch Smart DVI cascaded off port 2 of your first CPU Switch Smart DVI use:

3.8 Synchronising CPU Switch Smart DVIs for multiple video head

applications

Multiple CPU Switch Smarts may be connected together so that they operate in a synchronised manner. Synchronised operation is useful for applications that require multiple video signals to be switched together. This type of operation is usually required where each computer is fitted with multiple video cards or video cards with multiple video heads. Such configurations are typically required in banking and engineering applications where greater video 'real estate' is required. Whenever the CPU Switch Smart's channel is switched it sends an RS232 command out on its serial interface. The CPU Switch Smart switches its channel if it receives the same command on its serial interface. Consequently, by linking the serial interfaces a master unit may be made to automatically switch a daisy chain of slaved units as shown in the diagram below. The slave units will require the optional power adapters because they cannot draw their power from the video link alone.

4. CPU Switch Smart DVI configuration options

All the options described in this section are entered in CPU Switch Smart DVI configure mode - see section 2.6 for instructions on entering configure mode.

4.1 Screen saver time delay

CPU Switch Smart DVI contains a programmable screen saver which will blank the display after the set time delay with no keyboard or mouse activity. Simply typing at the keyboard or moving the mouse will re-enable the display. The display will flash whilst the CPU Switch Smart DVI is in screen save mode.

4.2 Autoscan ‘lock on’ mode and delay time

CPU Switch Smart DVI can be set to select each channel in turn for a period of time set by the autoscan delay time. Autoscan mode is entered by typing the hotkey keys together with ‘A’. By default, only those channels which have a powered up computer connected to them will be scanned. Sometimes it may be desirable to scan all channels, even if the attached computer is switched off (this will simply show a blank screen when it is selected). All the CPU Switch Smart DVI’s ports will be scanned if option L2 is selected. Some applications may also require the CPU Switch Smart DVI to power on in autoscan mode. This feature can be selected using the L3 or L4 options.

CPU Switch Smart DVI Installation and Use Page 29

Page 37

L1 - CPU Switch Smart DVI only locks on to active ports during autoscanning

(default) L2 - CPU Switch Smart DVI locks on to every port in turn during autoscanning L3 - CPU Switch Smart DVI powers on in autoscan mode and locks on to active

ports only L4 - CPU Switch Smart DVI powers on in autoscan mode and locks on to all ports

Note: Autoscan mode is ended simply by selecting a fixed channel using the keypad, the keyboard hotkeys or the mouse.

WARNING - Many modern monitors are fitted with automatic power save relays and will switch off after a few seconds if connected to an inactive PC. If you are using such a monitor you must not use the L2 feature. Constant switching on and off of your monitor's relay will eventually damage your monitor.

4.3 Mouse mode and mouse switching of channels

A three button PS/2 mouse or an IntelliMouse can be used to switch channels on the CPU Switch Smart DVI. To switch to the next channel, the user simply holds down the central button or wheel button and presses the left or right hand button to change the channel (see section 3.5). If the user does not wish to take advantage of this feature, it can be disabled by selecting U2, U3 or U5. If the third button is being used to switch the CPU Switch Smart DVI then it is not available for use with PC software although the function of an IntelliMouse wheel is not affected. Consequently in modes U1, U2 and U4 the CPU Switch Smart DVI reports to the PCs that a 2 button mouse is connected. If you wish to use the full function of a 3 button mouse or IntelliMouse for your PC software then you should select options U3 or U5.

CPU Switch Smart DVI Installation and Use Page 30

Page 38

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 Genius NetMouse Pro

Standard PS/2 and IntelliMouse compatible mice can be connected to the control port. You may configure your CPUs using Microsoft PS/2 or IntelliMouse drivers in any combination as required. The IntelliMouse features are supported on both PS/2 and RS232 CPU connections. When using PS/2 CPU connections, the CPU Switch Smart DVI will automatically configure itself to the type of mouse requested by the driver. If you are using RS232 CPU connections then you will need to select mouse options U4 or U5 to enable the IntelliMouse features.

U1 - CPU Switch Smart DVI channels are switchable using a 3 button mouse

or IntelliMouse (default) (CPU Switch Smart DVI reports 2 button mouse mode to PCs)

U2 - CPU Switch Smart DVI channels are not switchable using 3 button mouse

4.4 Keyboard hotkey combination

The keyboard hotkey combination is used to change a channel, set autoscan mode or secure the product (so that the password needs to be typed before it can be used

CPU Switch Smart DVI Installation and Use Page 31

Page 39

again). The following keyboard hotkey combinations can be selected. These hotkey combinations are used together with the command keys to trigger the required CPU Switch Smart DVI function. The left and right shift key combination is particularly suitable for extended keyboards where additional keys can be programmed to act as a combination of other keys. Such keyboards are supplied with many Gateway 2000 computers. Programming spare keys to trigger the hotkey combination allows channels to be selected via a single key stroke.

H1 - 'CTRL' and 'ALT' keys together (left or right hand keys operate) (default) H2 - 'CTRL' and 'SHIFT' keys together (left or right hand keys operate) H3 - 'ALT' and 'SHIFT' keys together (left and right hand keys operate) H4 - 'RIGHT ALT' key H5 - 'LEFT ALT' and 'RIGHT ALT' keys together H6 - ‘LEFT CTRL’ and ‘LEFT ALT’ keys together H7 - ‘RIGHT CTRL’ and ‘RIGHT ALT’ keys together H8 - No hotkey enabled

4.5 Cycling between all channels or just the active channels

The CPU Switch Smart DVI can be set to cycle between all channels or just the active channels when using ‘Hotkeys + Tab’ or a three button mouse to switch the channel. This avoids wasting time viewing channels that are not active. Option are:

U7 – Cycle between all ports when switching with ‘Hotkeys + Tab’ or three button mouse (default) U8 – Cycle between active ports only when switching with ‘Hokeys + Tab’ or three

button mouse

4.6 Firmware functions (version query, mouse restore and reset)

For technical support purposes, it may be necessary to find the firmware release version for the control software in your CPU Switch Smart DVI. For example, if the

release version is v1.29 the response shown to F1F1ff will be a brief display of the digit ‘1’, then F2F2ff will be a brief display of the digit ‘2’, then F3F3ff

will be a brief display of the digit ‘9’. You can reset all of the configured options back to the factory default states by typing F8F8ff. Use options F5F5ff and

F6F6ff to restore mouse function on disconnected PS/2 CPU mouse

connections.

CPU Switch Smart DVI Installation and Use Page 32

Page 40

F1 - Display firmware first digit (Note: F1 is FF followed by 11 NOT ll) F2 - Display firmware second digit F3 - Display firmware third digit F5 - Restore PS/2 mouse function to the currently selected CPU’s mouse port F6 - Restore IntelliMouse function to the currently selected CPU’s mouse port F8 - Reset all configurations to factory default settings. An ‘r’ will show briefly on the display to confirm that the reset has been completed.

4.7 Setting a security password

There are many situations where unrestricted access to corporate file servers or sensitive information needs to be controlled. In such circumstances, the CPU Switch Smart DVI can be locked away in a room or secure cabinet and controlled remotely. In this mode typing the keyboard hotkeys together with 'L' will blank the screen, disconnect the keyboard and mouse from all of the computers and display ‘P’ on the CPU Switch Smart DVI display. Control can only be regained by typing the correct password on the keyboard.

To set the password in configure mode, first type ‘P’ then (return). The display on CPU Switch Smart DVI will change to show ‘=' and you can then type your password. The password is not case sensitive and can be any combination of key strokes, including the function keys, but excluding the (ctrl), (alt), (shift) and (return) keys. When you have typed in your password type (return) to register it in the stored memory. Do not worry if you type the password incorrectly, you can always re-enter configure mode and set the password again. If you have lost the password and the CPU Switch Smart DVI is locked, the unit may be unlocked by powering down the CPU Switch Smart DVI, entering configure mode at power on (see section 2.6), and performing a complete reset using the F8 function.

NOTE - The password consists of a combination of key strokes rather like the code to a safe. The key strokes are not case sensitive and can include all the keys on the keyboard (except ctrl, alt, shift and enter). Consequently the following 'password' would be valid:

oFREDoFRED

CPU Switch Smart DVI Installation and Use Page 33

Page 41

4.8 Cascade query code

The CPU Switch Smart DVIs use a special ‘query code’ to detect whether or not they are connected to another CPU Switch Smart DVI. By default your CPU Switch Smart DVI uses query code AD. CPU Switch Junior (another range of keyboard / mouse / video switches from LINDY) units with firmware versions less than 1.09 used query code EF. This was found to conflict with a small number of other (rare) devices that used the same query code so an alternative query code was provided to ensure compatibility. Either query code may be used but you should make sure that all cascaded CPU Switch Smart DVI and CPU Switch Junior units are set to use the same query code. If any of the cascaded CPU Switch Juniors have firmware versions less than 1.09 then the cascade query code for all the CPU Switch Smart DVIs and SmartViews should be set to EF.

L7 – Cascade query code = AD (default) L8 – Cascade query code = EF

4.9 Resolving slow mouse problems

Due to certain technical reasons some systems running particular combinations of operating system and mouse drivers are sensitive to small timing changes relating to mouse communications. The introduction of a switch like the CPU Switch Smart inevitably causes some timing changes and in rare cases interactions have been observed that causes the mouse to run very slowly. Certain HP Vectra computers running later versions of Windows NT with Logitech mouse drivers and Logitech mice have been observed to exhibit such interactions with older switches. One solution to this problem is to change the mouse driver.

The CPU Switch Smart DVI is a high performance device that is carefully engineered to minimise such interactions and should not exhibit this characteristic. Nevertheless such interactions are unpredictable and so the CPU Switch Smart is fitted with a feature that ensures that the mouse can never operate at a very slow rate regardless of such interactions. This feature is activated using the following options:

L5 – Allow the mouse to run at any speed (default) L6 – Don't allow the mouse to run at very slow speeds

CPU Switch Smart DVI Installation and Use Page 34

Page 42

4.10 Exit configure mode

When you have finished configuring any special options, simply type ‘E’ followed by (return) to exit configure mode and return to normal operation mode. The attached computers can now be switched on.

Appendix A. Cable and connector specifications

IMPORTANT NOTE

The maximum cable lengths supported vary widely between devices and cables. It may be possible to use cables that are longer than those specified below with certain PCs and peripherals but this cannot be guaranteed. If you experience problems try using shorter cables.

A1. Keyboard, monitor and mouse to CPU Switch Smart DVI

All of the shared devices plug directly into the relevant ports at the rear of the CPU Switch Smart DVI. If you use an AT style keyboard you will need an AT (5 pin DIN female) to PS/2 (6 pin mini-DIN male) converter.

Cable specification (interface-powered operation):

Keyboard and mouse cables should be no longer than 2 metres. For full DVI video resolution of 1600 x 1200 @ 60Hz, the DVI cable should ideally not exceed 2 metres. The CPU Switch Smart DVI will typically drive the following DVI cable lengths. Greater resolutions may be achievable with some monitors. Up to 5 metres at a resolutions of 1280 x 1024 @ 60 Hz Up to 10 metres at a resolutions of 1024 x 768 @ 60 Hz

Cable specification (with optional power adapter):

Keyboard and mouse extension cables can be used to increase the distance from the CPU Switch Smart DVI up to 10 metres. Most keyboards and mice will also operate up to distances of 20 metres. See above for DVI video cable specifications (these don’t change significantly from the “interface powered” configuration).

A2. CPU Switch Smart DVI to PCs 1 to 4

Cable specifications:

Video – Single-link DVI-D male-to-male cables of 2 to 10 metres. High quality DVI

cables must be used - low quality cables may lead to visible noise on the display. For full DVI resolution of 1600 x 1200 @ 60Hz, the cable should ideally not exceed 2 metres.

The maximum DVI cable length that can be used from the PC to the CPU Switch Smart DVI will vary from PC to PC depending upon the computer’s video card, but typically 5 metres is achievable at a resolution of 1280 x 1024 @ 60 Hz and 10 metres is achievable at a resolution of 1024 x 768 @ 60 Hz

Keyboard and PS/2 mice - 6 pin mini-DIN male connector to 6 pin mini-DIN male connector with all lines connected straight through (1-1,2-2 etc.). For ‘interface powered’ operation without the optional power adapter the cables should be no longer than 5 metres (see section 2.4 for more details). For operation with the power adapter, cables should be no longer than 30 metres.

RS232 serial mice - these require a special converter to connect the RS232 lines present on the CPU Switch Smart DVI mouse ports to the RS232 port on a PC.

Cables should be no longer than 30 metres.

NOTE - There are several common wiring specifications for 6-pin mini-DIN to 9-pin serial adapters. If you have an adapter that has been supplied with a mouse it may have a completely different internal wiring to that shown above and may not be compatible with the CPU Switch Smart

Appendix B. Problem Solving

Problem:

Noise on video display.

Action:

Use higher quality DVI video cables. Reduce graphics card resolution or refresh rate. Use a shorter DVI cable.

Problem:

Mouse does not move cursor on screen.

Action:

Ensure that the mouse and computer are both connected to CPU Switch Smart DVI before power is connected and ensure that the CPU Switch Smart DVI is powered on before the attached computer. Ensure that your software is configured to accept a Microsoft compatible mouse of the type that you have connected (PS/2 or RS232). If you move the mouse and the activity indicator (dot on 7 segment display) does not flash then the CPU Switch Smart DVI is not receiving data from the mouse. Check the mouse connection to the CPU Switch Smart DVI, try resetting the mouse using the reset function (section 2.10) or re-powering the CPU Switch Smart DVI. If you are attempting to connect the CPU Switch Smart DVI to a CPU with a PS/2 mouse connection that has not been powered down then you will need to use the mouse restoration functions F5 or F6 (see section 2.11).

Problem:

Keyboard does not function or functions intermittently. Num lock light does not always come on when the num lock key is pressed.

Action:

Some older keyboards were designed for use with specific computers and are not truly AT or PS/2 compatible. These are not common but if you experience problems try another keyboard.

Problem:

Mouse causes channel to change.

Action:

Some cheaper mice are not fully compatible with the CPU Switch Smart DVI and can lose data causing the channel to be changed (if mouse switching of channels is enabled). If you experience this problem then change the mouse and use a Microsoft, Logitech, IBM, Compaq or Hewlett-Packard type. Ensure that you are using a Microsoft compatible mouse driver on your PC. Some other manufacturers’ drivers may switch the mouse to use a proprietary mouse data format not supported by the CPU Switch Smart DVI. If you have unplugged and re-connected a mouse to the CPU Switch Smart DVI then ensure that you reset it using the mouse reset function (see section 2.10).

Problem:

Mouse jumps around the screen after disconnecting the mouse cable or powering down the CPU Switch Smart DVI.

Action:

If you have disconnected and re-connected a CPU mouse cable or you have powered down the CPU Switch Smart DVI then the mouse data format may be out of synchronisation with that required by the PC (PS/2 or Intellimouse). Try the ‘restore Intellimouse’ function (F6) to resolve the problem or repower the CPU.

Problem:

Mouse moves very slowly but otherwise functions correctly.

Action:

Change the mouse driver to a Microsoft type or take the action recommended in section 4.9.
