2. Installation
2.1 What you will need
•Cables to connect the LINDY CPU Switch Junior to each of your PC keyboard, video and
mouse ports. Cable specifications are given in appendix B. (You do not need to connect a
mouse cable if you are not using the mouse).
•A monitor with a standard VGA/SVGA (15 HD pin) connector that will work when connected
directly to each of your PCs. LINDY CPU Switch Junior 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 Junior 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 compatible mouse. If you wish to use the mouse to switch the LINDY CPU Switch
Junior’s channel then you will need a three button mouse or an IntelliMouse.
(The LINDY CPU Switch Junior 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).
•Mouse drivers that use a compatible data format to the Microsoft®IntelliMouse. You may
need to try these to assess their compatibility.
•Use of PS/2 and RS232 style mice with the LINDY CPU Switch Junior - All of the mouse
connections from LINDY CPU Switch Junior to PCs support either a PS/2 or an RS232 mouse.
LINDY CPU Switch Junior 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. This adapter is the same as is shipped with Microsoft®auto-sensing mice. The
LINDY CPU Switch Junior will operate without a mouse connected if you do not wish to use
one.

LINDY ELECTRONICS LTD Installation & Use – English Guide Page 9
2.2 Mounting the LINDY CPU Switch Junior
LINDY CPU Junior 2 & 4 Switches LINDY CPU Junior 4 OSD & 8 OSD Switches
The LINDY CPU Junior Switch has
been designed to be used either on a
desktop or mounted close to the
computer system boxes which it is
serving.
The LINDY CPU Switch has been designed to be used
either on a desktop or mounted in a 19 inch rack. If it is
to be used on a desktop then you will need to stick the
supplied self-adhesive rubber feet to the underside of
the LINDY CPU Junior OSD switch. If you wish to mount
it in a 19” rack then you will need to fit the rack mounting
brackets to the side of the LINDY CPU Junior OSD. The
19” rack mounting brackets are supplied in the optional
rack mounting kit (part 32 285).
2.3 Connecting your devices
Ensure that the optional power adaptor is disconnected from the LINDY CPU Switch Junior and
that all the devices which are to be attached are switched off. Connect the shared keyboard, PS/2
mouse and monitor to the control port connectors (see figures 1, 2, 4 & 5). 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 supplied in the cabling pack as
shown below. Alternatively, if you have chosen to purchase specific cable lengths, refer to
appendix A for cable specifications.
The LINDY CPU Switch Junior is now ready for use. It will start to operate as soon as one of the
connected CPUs is powered on or the optional power adaptor is connected. The power light (on
non-OSD models), confirms that sufficient power is available to operate the LINDY CPU Switch
Junior. If you are connecting to PCs using cables that are longer than 3 metres or are cascading
the switch to another you will need to use the optional power adaptor. When using the optional
power adaptor, ensure that is is connected to the mains and powered on before you switch on any
of the connected computers. Failure to switch the LINDY CPU Switch Junior and computer(s) on in
the correct order can lead to the mouse and/or keyboard not being recognised by the computers
when they are switched on.

Page 10 Installation & Use – English Guide LINDY ELECTRONICS LTD
2.4 ‘Self powered’ operation without the optional adaptor
The LINDY CPU Switch Junior draws its power from the connected computers via the keyboard
cables. A single keyboard connection is normally sufficient to power the LINDY CPU Switch Junior
provided that the cable is no longer than 3 metres. If more than one computer is connected then
the power will be intelligently drawn from all computers. Cables longer than 3 metres may be used
provided that the LINDY CPU Switch Junior is already powered by another connected computer or
the optional power adaptor. If you are cascading the LINDY CPU Switch Junior to another then a
power adaptor must be connected to all LINDY CPU Switch Juniors.
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, but bearing in mind the following points:
•LINDY CPU Switch Junior emulates Microsoft®compatible serial, IntelliMouse 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.
•LINDY CPU Switch Junior supports VGA/SVGA/XGA/XGA2 type monitors, but does not
support the automatic detection features available with some ‘plug and play’ monitors and
video cards. If you have this type of video card and monitor, you should select the video mode
manually instead of relying upon the automatic detection feature.
2.6 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 Junior 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 Junior 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 Junior 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 2.7 for details.
Keyboard and mouse mode switching - The LINDY CPU Switch Junior 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 Junior channel is switched thus ensuring maximum software compatibility. The
<NUM LOCK>, <CAPS LOCK> and <SCROLL LOCK> states are an obvious example of this
process.

LINDY ELECTRONICS LTD Installation & Use – English Guide Page 11
2.7 Re-enabling a disconnected PS/2 mouse
If you disconnect the shared PS/2 mouse from the LINDY CPU Switch Junior 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 Junior is fitted with an
automatic mouse recovery system.
LINDY CPU Switch Junior 2 & 4 LINDY CPU Switch Junior OSD 4 & 8
With the PS/2 mouse disconnected, change the channel using the keypad or keyboard hotkeys.
The LINDY CPU Switch Junior detects that the mouse has been disconnected and triggers the
automatic recovery system. Plug in the PS/2 mouse and the LINDY CPU Switch Junior will re-
initialise it.
You may also re-enable a disconnected PS/2
mouse by using the keyboard and mouse reset
function (see section 4.3). **
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 Junior
OSD, press the front panel 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.
2.8 Hot plugging the LINDY CPU Switch Junior 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
Junior before installation. However if this is not possible then most systems can be hot plugged by
using the LINDY CPU Switch Junior’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 Junior 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 Junior's mouse restoration functions.
IMPORTANT NOTE
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 Junior. 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.

To restore lost mouse movement on a CPU connected to the LINDY CPU Switch Junior:
1) Select the CPU that has lost its mouse movement
2) Press the select key on the front of the LINDY CPU Switch Junior for 5 seconds until lights 1
and 2 are displayed together (or ‘C’ appears on OSD models). The LINDY CPU Switch Junior
is now in maintenance mode.
3) To restore a PS/2 mouse connection press 
Or, to restore an IntelliMouse connection press


Note, on the LINDY CPU Switch Junior OSD 4 and 8 port, you must press the <ENTER> key after
selecting the option required. For example, to restore a PS/2 mouse connection press
)x
4) Test the mouse movement by slowly moving the mouse a short distance. In most cases the
mouse should now work and no further action will be necessary
5) If the mouse darts uncontrollably around the screen then there are two possible reasons.
Firstly the CPU may be expecting a different mouse data packet format. A PS/2 mouse sends a
3 data character report and an IntelliMouse sends a 4 data character report. If you are in doubt
then try setting the other data format (see step 3).
Secondly, the data packet format may be correct but the LINDY CPU Switch Junior and the
CPU may not be correctly synchronised. In other words the LINDY CPU Switch Junior may be
sending the first data character whilst the CPU is expecting the second data character. Most
PC mouse drivers will automatically re-synchronise themselves if no mouse data has been
received and so this is not normally a problem. However some mouse drivers do not
automatically re-synchronise. The LINDY CPU Switch Junior is fitted with a re-synchronisation
function that allows the synchronisation between the LINDY CPU Switch Junior and the CPU to
be altered by 1 data character. Using this function the synchronisation between the LINDY
CPU Switch Junior and the CPU can be matched.

LINDY ELECTRONICS LTD Installation & Use – English Guide Page 13
To attempt to re-synchronise the mouse press the key on the front of the LINDY CPU Switch
Junior for 5 seconds until lights 1 and 2 are displayed together. The LINDY CPU Switch Junior
is now in maintenance mode.
Now press on the keyboard. Test the mouse function and repeat this procedure up to 3
times until correct mouse operation is restored.
Note, the above option of using on the keyboard is available on the LINDY CPU Switch
Junior (non OSD models) only. The OSD models have an automatic re-synchronise facility

3. Using the LINDY CPU Switch Junior
This section explains the general operation of the LINDY CPU Switch Junior. We recommend that
you read this section before starting to use the product.
3.1 Power indicator
LINDY CPU Switch Junior 2 & 4 LINDY CPU Switch Junior OSD 4 & 8
The LINDY CPU Switch Junior
draws its power from the attached
CPUs via the keyboard cables.
The green power light confirms
that there is sufficient power
available. If the power light flashes
or is off continuously then there is
not sufficient power available.
At power on the LINDY CPU Switch Junior OSD selects
PC number 1 and displays ‘1’. If a password has been
set then ‘P’ will be displayed and the LINDY CPU Switch
Junior OSD will remain locked until a valid password is
entered.
If there is insufficient power available from the

The channel lights indicate the currently
selected channel. The currently illuminated
channel light will flash to indicate keyboard
and mouse activity. In auto-scan mode the
lights alternate between showing the currently
selected port and indicating that the LINDY
CPU Switch Junior is in auto-scan mode by
flashing all the lights. Channel lights 1 and 2
are illuminated together when the LINDY
CPU Switch Junior is in maintenance mode.
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
the LINDY CPU Switch OSD 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.

Page 16 Installation & Use – English Guide LINDY ELECTRONICS LTD
3.4 Keyboard hotkey control
LINDY CPU Switch Junior can be conveniently controlled by selecting channel, autoscan mode or
auto-scan mode 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 tand
s, although other combinations can be selected. 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 Junior. HOTKEYs + vis an exception and this allows you

3.5 On Screen Menu control
IMPORTANT NOTE
This next section dealing with the On Screen Menu control is a feature only supported on the
LINDY CPU Junior 4 OSD & 8 OSD models.
On-Screen Menu
LINDY CPU Junior Switch can conveniently select a computer using the integral On Screen Menu
control. The menu is called up by pressing the two ‘HOTKEYs’ and 0. When the menu is first
called up, there will be no named computers listed. You must first enter the names and port
numbers for computers which are to be selected from the menu.
Adding a computer to the menu list
With the menu visible on the screen, press the <INSERT> key. This will cause a new Computer
entry field to be inserted on the menu. This is highlighted in red with a flashing cursor to indicate
the text entry position. Type in a name up to 16 characters long. You can use upper/lower case,
special and space characters. When completed press the <ENTER> key. The red highlighted area
now moves into the Port entry field and you can enter the port number for the named Computer. If
you are using cascaded LINDY CPU Junior Switches, the cascade routing will need to be entered
(see section 3.9 for more details). To specify port 5 on a LINDY CPU Junior Switch that is
cascaded off port 3 you would enter port number 35. Units can be cascaded three levels deep.
Now press <ENTER> again to complete the entry and store it in the menu memory.
Note that you can add another Computer to the menu list at any time. If you just use the
<INSERT> key, the entry will be placed after the current line. To place an entry before the current
line use <SHIFT> and <INSERT> together, then edit the new name as already described.
Deleting a computer from the menu list
With the menu visible on the screen, highlight the computer to be deleted and press the
<DELETE> key. To confirm deletion press <ENTER>. To abandon deletion press <ESC>.

Editing a computer on the menu list
With the menu visible on the screen, highlight the computer to be edited and press the <SHIFT>
and <DELETE> keys together. Type in the new Computer name and port then press <ENTER>.
To abandon editing press <ESC>.
Selecting a computer on the menu list
With the menu visible on the screen, highlight the computer to be selected using the cursor p/
oor <PAGEUP> / <PAGEDOWN> keys as required. Press the <ENTER> key to switch to the
highlighted computer. LINDY CPU Junior Switch has an advanced ‘connection confirmation’ facility
which is particularly useful in systems where many computers are displaying the same or very
similar video. The selected computer name and port number will briefly flash up on the screen to
confirm the selection has been made. If it is not possible to make the connection, perhaps because
a cascaded unit is not switched on or is in use locally, the menu will flash ‘computer unavailable’
until the <ESC> key is pressed.
