2. Installation
2.1 What you will need
Cables to connect the LINDY CPU Switch Smart 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 standard VGA/SVGA (15 pin) connector that will work when
connected directly to each of your PCs. LINDY CPU Switch Smart supports low and
high resolution monitors.
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 LINDY CPU Switch Smart 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 LINDY CPU Switch Smart’s channel then you will need a
three button mouse or an IntelliMouse.
(The LINDY CPU Switch Smart 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 LINDY CPU Switch Smart - All of the
mouse connections from LINDY CPU Switch Smart to PCs support either a PS/2 or
an RS232 mouse. LINDY CPU Switch Smart automatically converts from the PS/2
mouse commands to RS232 serial mouse commands. Serial mice types are
selected by using an adapter as described in Appendix A. The LINDY CPU Switch
Smart will operate without a mouse connected if you do not wish to use one.

2.2 Mounting the LINDY CPU Switch Smart
The LINDY CPU Switch Smart 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 LINDY CPU Switch Smart 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 LINDY CPU Switch
Smart 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
LINDY CPU Switch Smart (see figs 1, 2 and 3). Next, connect each computer
system unit in turn with the keyboard cable, mouse cable and video cable. LINDY 3-
in-1 keyboard/video/mouse cables are recommended for maximum convenience.
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 LINDY as
there are several different standard wiring configurations for these adapters.
The LINDY CPU Switch Smart 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 LINDY CPU Switch Smart
to another LINDY CPU Switch Smart 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 LINDY CPU Switch Smart before you switch on the
LINDY CPU Switch Smart

connected computers. Failure to switch the LINDY CPU Switch Smart 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 LINDY CPU Switch Smart draws its power from the connected computers via
the keyboard cables. A single keyboard connection is normally sufficient to power
the LINDY CPU Switch Smart 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 LINDY
CPU Switch Smart is already powered by another connected computer or the
optional power adapter. If you are cascading the LINDY CPU Switch Smart to
another LINDY CPU Switch Smart then a power adapter must be connected to all
LINDY CPU Switch Smarts.
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. LINDY CPU Switch Smart 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.
2.6 Configuring the LINDY CPU Switch Smart
The LINDY CPU Switch Smart 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 LINDY CPU Switch Smart’s
EEPROM memory and are retained when the power is disconnected.
The options may be changed whilst the LINDY CPU Switch Smart is in configure
mode. You may enter configure mode at initial power on or whilst the LINDY CPU
Switch Smart is running:
To enter configure mode at power on:
Switch off all the attached PCs and the LINDY CPU Switch Smart. Hold down the
front panel key whilst powering on the LINDY CPU Switch Smart. Remember that
the LINDY CPU Switch Smart 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
LINDY CPU Switch Smart displays ’C’ to show that it has entered configure mode.
To enter configure mode whilst the LINDY CPU Switch Smart is running:
Hold down the front panel key for 5 seconds until the front panel display shows ‘C’.

2.8 Resetting the LINDY CPU Switch Smart without disconnecting
your devices
The LINDY CPU Switch Smart 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 LINDY CPU Switch Smart 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 LINDY CPU Switch Smart 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 LINDY CPU Switch Smart 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.
Unplugging the mouse from the LINDY CPU Switch Smart 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 LINDY CPU Switch Smart 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 LINDY CPU Switch Smart 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 LINDY CPU Switch Smart 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 LINDY CPU Switch Smart 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
LINDY CPU Switch Smart is fitted with an automatic mouse recovery system.
With the PS/2 mouse disconnected, change the channel using the keypad or
keyboard hotkeys. The LINDY CPU Switch Smart detects that the mouse has been
disconnected and triggers the automatic recovery system. Plug in the PS/2 mouse
and the LINDY CPU Switch Smart 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 LINDY
CPU Switch Smart, 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.
2.11 Hot plugging the LINDY CPU Switch Smart 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 LINDY
CPU Switch Smart before installation. However, if this is not possible then most
systems can be hot plugged by using the LINDY CPU Switch Smart’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 LINDY CPU Switch Smart 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 LINDY CPU Switch Smart'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 LINDY CPU Switch Smart. 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.

2.12 Upgrading the LINDY flash memory
The LINDY CPU Switch Smart 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 LINDY’s options port and running an upgrade program on the
PC. This upgrade program downloads the new firmware to the LINDY CPU Switch
Smart and checks that the data has been programmed correctly.
To perform a firmware upgrade on your LINDY CPU Switch Smart 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 Technology or may be made using the wiring specification
given in Appendix A4. You will also need to download the latest version of the
LINDY CPU Switch Smart firmware which is available free of charge at
To perform a flash upgrade on the LINDY CPU Switch Smart:
Step 1 - Connect your computer to the LINDY CPU Switch Smart
Connect your computer’s serial port to the LINDY CPU Switch Smart’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 LINDY CPU Switch Smart to the ON
position.
Step 3 - Reset the LINDY CPU Switch Smart
Reset the LINDY CPU Switch Smart by moving option switch 8 to the ON position
(halt and reset) and then back to the OFF position (normal operation). Alternatively
LINDY CPU Switch Smart

you may reset the LINDY CPU Switch Smart by powering off all the attached
computers and removing the optional power adapter.
Step 4 - Ensure that the LINDY CPU Switch Smart is powered on
Ensure that the LINDY CPU Switch Smart is powered on. It is normally possible to
upgrade the LINDY 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 LINDY 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 LINDY CPU Switch Smart firmware is available from the
supplied as a pair e.g.
CPUSS129.EXE
CPUSS129.HEX
and should be downloaded to the same directory on your PC. Run the file
CPUSSxxx.EXE (e.g. CPUSS129.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.

Some useful issues to bear in mind when performing flash upgrades
The upgrade program rewrites the LINDY CPU Switch Smart’s firmware code. If the
upgrade process is interrupted then the LINDY 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 LINDY
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 LINDY CPU Switch Smart or computing equipment. For
obvious reasons, the code that the LINDY 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 LINDY CPU Switch Smart or computing
equipment.

3. Using the LINDY CPU Switch Smart
This section explains the general operation of the LINDY CPU Switch Smart. We
recommend that you read this section before starting to use the product.
3.1 Power on status
At power on the LINDY CPU Switch Smart selects computer 1 and displays ’1’. If a
password has been set then ‘P’ will be displayed and the LINDY CPU Switch Smart
will remain locked until a valid password is entered.
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 LINDY CPU Switch Smart’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 LINDY CPU Switch Smart’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 LINDY CPU Switch Smart. This is
particularly useful in applications where the LINDY CPU Switch Smart 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 LINDY CPU Switch
Smart 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.

3.4 Keyboard hotkey control
LINDY CPU Switch Smart 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 LINDY CPU
Switch Smart. 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 LINDY CPU Switch Smart 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 re-
enabled by selecting a channel.
‘HOTKEYs’ and ‘L’ - disables the LINDY CPU Switch Smart’s keyboard and mouse
and displays 0. The video signal is switched off. If a password has not been set then
the LINDY CPU Switch Smart can be re-enabled by selecting a channel. If a
password has been set then the LINDY CPU Switch Smart 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.

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 LINDY 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 previous numerical channel in sequence will be selected (see section 4.5 for
more details). Mouse switching may be enabled or disabled by setting options
during configuration (see section 4.3). When mouse switching is disabled the third
button or wheel button state is ‘passed through’ the LINDY CPU Switch Smart and
seen by the application software.

3.6 RS232 control
LINDY CPU Switch Smart 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 LINDY CPU Switch Smart.
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 LINDY 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 LINDY CPU
Switch Smart. Pin assignments for this connector are given in appendix A
3.7 Cascading LINDY CPU Switch Smarts
LINDY CPU Switch Smart switches can be connected together to expand the
number of connected computers. When cascading LINDY CPU Switch Smarts a
power adapter must be connected to each LINDY CPU Switch Smart. LINDY CPU
Switch Smarts 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 30 metres
away from the next LINDY CPU Switch Smart. The channel can be selected on
remote LINDY CPU Switch Smart units using an extension of the HOTKEY control .
For example, consider a situation where two LINDY CPU Switch Smart units are
connected together as shown below. To connect to the computer attached to port 3
on LINDY CPU Switch Smart 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 LINDY CPU Switch Smart which is connected
into port ‘2’ of the first LINDY CPU Switch Smart unit A.
For example to connect to port 3 on the LINDY CPU Switch Smart cascaded off port

3.8 Synchronising LINDY CPU Switch Smarts for multiple video
head applications
Multiple LINDY 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 LINDY CPU Switch Smart’s channel is switched it sends an RS232
command out on its serial interface. The LINDY 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.

B8 - Blank screen after 20 minutes of inactivity
4.2 Autoscan ‘lock on’ mode and delay time
LINDY CPU Switch Smart 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 LINDY CPU Switch Smart’s ports
will be scanned if option L2 is selected. Some applications may also require the
LINDY CPU Switch Smart to power on in autoscan mode. This feature can be
selected using the L3 or L4 options.

T4 - 10 seconds autoscan delay time before switching to next port
T5 - 15 seconds autoscan delay time before switching to next port
T6 - 20 seconds autoscan delay time before switching to next port
T7 - 30 seconds autoscan delay time before switching to next port
T8 - 60 seconds autoscan delay time before switching to next port
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
LINDY CPU Switch Smart. 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 LINDY CPU Switch Smart 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 LINDY CPU Switch Smart 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.

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 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)

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 LINDY CPU Switch Smart 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 LINDY CPU Switch Smart. For example, if
the release version is v1.29 the response shown to )ꢂI will be a brief display
of the digit ‘1’, then )ꢁI will be a brief display of the digit ‘2’, then )ꢅI
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 )ꢆI. Use options )ꢃI and

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 LINDY CPU
Switch Smart 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 LINDY CPU Switch Smart 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
LINDY CPU Switch Smart 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
LINDY CPU Switch Smart is locked, the unit may be unlocked by powering down the
LINDY CPU Switch Smart, 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:

4.8 Cascade query code
The LINDY CPU Switch Smarts use a special ‘query code’ to detect whether or not
they are connected to another LINDY CPU Switch Smart. By default your LINDY
CPU Switch Smart uses query code AD. LINDY CPU Switch Junior OSD (another
range of keyboard / mouse / video switches from LINDY Technology) 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 LINDY CPU Switch Smart and
LINDY CPU Switch Junior OSD units are set to use the same query code. If any of
the cascaded LINDY CPU Switch Junior OSDs have firmware versions less than
1.09 then the cascade query code for all the LINDY CPU Switch Smarts and LINDY
CPU Switch Junior OSDs 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 LINDY 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 LINDY CPU Switch Smart 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 LINDY 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

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 LINDY CPU Switch Smart
All of the shared devices plug directly into the relevant ports at the rear of the LINDY
CPU Switch Smart. 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 (self-powered operation):
Keyboard, monitor and mouse cables should be no longer than 2 metres.
Cable specification (with optional power adapter):
Keyboard, monitor and mouse extension cables can be used to increase the
distance from LINDY CPU Switch Smart up to 10m. Most keyboards and mice will
also operate at distances of 20 metres.
A2. LINDY CPU Switch Smart to PCs 1 to 4
Cable specifications:
Video - 15 pin high density male D connector to 15 pin high density male D
connector wired as a standard VGA PC to monitor cable. There are two types
commonly available. The best type cables which will give excellent quality are
constructed with coaxial cable cores. Cheaper ‘data’ cables are often used, but can
degrade video quality if used over longer distances. Avoid using 'data' cables longer
than 2 metres unless the video quality is not important. Good quality coaxial video
cables may be run at distances up to 30 metres with little loss of video quality. If you
wish to make use of the DDC (Display Data Channel) capabilities of the LINDY CPU
Switch Smart then you will need to use cables that have the DDC signalling lines
connected (pins 12 and 15 on the 15-way video connector). Not all video cables

have these DDC lines connected.
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.). If the PC has a 5-
pin DIN AT style keyboard connector you will need a PS/2 to AT keyboard adapter
6-pin mini-DIN female to 5-pin DIN male (readily available). 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 LINDY CPU Switch Smart 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 LINDY CPU Switch Smart

Recommended cables:
3-in-1 keyboard, video and mouse combination cable - For convenience,
neatness and high video quality we recommend the LINDY brand 3-in-1 combination
cables. These cables are constructed with tri-coax video links to ensure that high
video quality is maintained. They also support DDC signalling and are colour coded
in PC99 specification colours for your convenience. These match the colours used
on the back of your LINDY CPU Switch Smart and most modern PCs. These cables
are available in various different lengths to suit your requirements. They may be
purchased with or without the adapters for AT keyboards and RS232 serial mice.

Appendix B. Problem Solving
Problem: Poor video quality with smearing fuzziness or ripple.
Action: Use screened coaxial video cables to connect your devices.
Problem: Mouse does not move cursor on screen.
Action: Ensure that the mouse and computer are both connected to LINDY CPU Switch
Smart before power is connected and ensure that the LINDY CPU Switch Smart 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 LINDY CPU Switch Smart is not receiving data from the mouse. Check the mouse
connection to the LINDY CPU Switch Smart, try resetting the mouse using the reset
function (section 2.10) or re-powering the CPU Switch Smart. If you are attempting to
connect the CPU Switch Smart 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 LINDY CPU Switch Smart 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 LINDY CPU Switch
Smart. If you have unplugged and re-connected a mouse to the LINDY CPU Switch Smart
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 LINDY CPU Switch Smart.
Action: If you have disconnected and re-connected a CPU mouse cable or you have
powered down the LINDY CPU Switch Smart 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 re-power the CPU.
Problem: Mouse moves very slowly but otherwise functions correctly.
