1. Introduction
Thank you for purchasing the LINDY Extender C5 PRO-300. This KVM Extender set allows you to place the
controlling keyboard, video monitor, mouse, audio accessories (and also a serial device) up to 300 metres from
a system. The LINDY Extender C5 PRO-300 set consists of two modules: a local module that attaches to your
computer system and a remote module to which the peripherals are connected. The long distance link between
the two modules is made via Category 5, or higher, twisted pair cabling. There is no particular advantage in
using higher specification Category 6 cables. On the contrary it may even result in unacceptable video quality if
you use a) Category 6 and b) shielded cable.
Special circuitry within the remote module allows you to make adjustments to the sharpness and brightness
settings to suit your own preferences. Additionally, the LINDY Extender C5 PRO-300 also features Skew
adjustment to counteract the effects of uneven lengths of twisted pair cables that are used to carry the video
signals.
Twisted Pair Cable
(up to 300m)
Throughout this document, the LINDY Extender C5 PRO-300 is
commonly abbreviated to Extender C5

2.1 Configuration switch settings
The basic operations of the LOCAL and REMOTE modules are controlled by the banks of four switches located
on the side of each module. The switches are monitored at all times and may be changed when power is on or
off (the only exception to this rule is switch 1 of the LOCAL module which initiates slightly different functions
depending on the power state when it is switched).
Note: When shipped, all switches are set in the OFF positions and this will produce normal operation with
normal microphone input (at the REMOTE module.)
LOCAL Switch 1
OFF: Normal operation
ON:
(Before power is applied) Places the LOCAL module into flash upgrade mode so that the internal
software can be changed. (See section 6. Flash upgrade procedure)
ON:
(Whilst power is applied) Places the REMOTE module into password override mode. This allows any
pre-configured passwords to be altered – particularly useful when they have been lost or forgotten. (See
section 5.5 Password override.)
LOCAL Switch 2
OFF: Normal operation.
ON:
Set transparent mode. Use this setting if the Extender C5 modules are to be used with KVM switches
that are not manufactured by LINDY Electronics. Cascaded KVM switches often use special signals to
set or identify conditions. In transparent mode, the Extender C5 modules will pass the signals without
attempting to interpret them.
LOCAL Switch 3
OFF: Microphone input on REMOTE module. Use this setting if a standard mono-channel microphone is
connected to the microphone input on the REMOTE unit.
ON:
Stereo line-in input on REMOTE module. Use this setting if a stereo input is applied to the microphone
input on the REMOTE unit.
LOCAL Switch 4
OFF: Normal operation.
ON:
Suspend operation and reset the LOCAL module. Use this setting momentarily to
produce the same effect as removing and restoring power if incorrect operation has
occurred. Return the switch to the OFF position to allow normal operation to continue.

software can be changed. (See section 6. Flash upgrade procedure)
Note: When shipped, all switches are set in the OFF positions and this will produce normal operation.
REMOTE Switches 2 and 3
Switches 2 and 3 determine which two keyboard keys (when pressed in unison) are to be designated as
‘hotkeys’. Hotkeys signal to the REMOTE module that the next key to be pressed is a special configuration
command for the module and is not to be passed to the computer system.

2.2 Mounting a module – desk or rack
The Extender C5 modules can be situated on a desk (or floor) or alternatively, for larger installations, mounted
within optional rack mount chassis units.
General remark
ƒ
ƒ
For correct operation, the local and remote units must have ground connections: At the computer end,
ensure that the computer or KVM switch that the LOCAL module is connected to has a ground connection.
At the keyboard/monitor/mouse end, ensure that the REMOTE module’s power supply is connected to a
grounded power outlet. Alternatively, a ground connection will be made via the monitor, if the monitor is itself
grounded.
Try to avoid running the interconnect cable alongside power cables where possible.
Desk mount
Apply the supplied self-adhesive rubber feet to the underside of the module(s)
Rack mount
Note: The module switches are not accessible once it is inserted into
the rack, therefore, check all settings before insertion.
1
Place the rack securing plate (available as
a separate kit) onto the front of the module
and secure it with the two countersunk
screws.
2
3
Orientate the module on its side so that its
labelled face is the correct way up and the
securing plate is facing away from the rack.
Slide the module into the required rack
position. The rectangular cut-out in the
front upper lip of the rack allows the two
screws on the module’s upper edge to slide
through.
4
5
The rack mount chassis has a series of
holes in its floor that are spaced to
accommodate the two screws on the
module’s lower edge. Ensure that the
screws correctly locate into the two holes of
the chosen slot. The rack securing plate on
the module should now be flush with the
front of the rack mount chassis.
Use the third (pan-head) screw, in the top
hole of the rack securing plate to fasten the
module to the rack.

3. Connections
The naming of the LOCAL and REMOTE modules relate to their proximity to the computer system. Hence, the
LOCAL module connects directly to the system, while the REMOTE is at the other end of the twisted pair cable
and attaches to the keyboard, mouse, etc.
Connections at the LOCAL module
3.1 KVM+A multi-cable connection
Most of the connections between the computer system and the LOCAL module are made via the supplied multi-
cable. This has a single connection to the module, is two metres in length and splits out to the keyboard, video,
mouse, microphone and speaker ports of the system.
1.
2.
Attach the supplied KVM+A multi-cable to the 25-way socket at the end of the LOCAL module.
At the other end of the KVM+A cable, attach the keyboard, mouse and video, microphone, and speaker
connectors to the appropriate sockets at the rear of the computer system. On most systems the
appropriate ports should be labelled and colour coded in a similar way to the cable connectors:
Monitor
Keyboard
Mouse
Speaker
Microphone
Blue
Purple
Mid green
Light green
Pink (or maroon)

3.2 Serial cable connection
The Extender C5 set offers the option to attach an RS232 serial device (such as a touch screen input) via the
remote link. The link supports software or hardware handshaking up to a maximum baud rate of 56 Kb/s. To
make the serial connection between the LOCAL module and your computer system, use the supplied serial link
cable.
1
2
Attach the male connector of the serial link cable to the 9 pin port on the LOCAL module.
Connect the other end of the serial link cable to the appropriate serial port of the computer system.
3.3 Twisted pair connection
The link between the LOCAL and REMOTE modules is made via twisted pair cable, specified to Category 5 or
higher. Ensure that the total twisted pair cable length (including patch boxes) does not exceed 300 metres.
1
Insert the connector from the twisted pair cable link into the socket.
Optional power connection
The LOCAL module usually derives its power from the keyboard connection of the host system.
If the keyboard connection will not be used then you will need to use an external power supply
of the same type used for the REMOTE module.
These are available from your LINDY supplier.

3.6 Audio connections
Audio connections are available at the two 3.5” jack sockets mounted
on the side (same side as the switch bank) of the REMOTE module.
Note: The microphone input has a dual function whereby it can either support a mono-channel microphone or
alternatively receive stereo line input. Switch 3 on the LOCAL module controls the setting of this port: LOCAL
switch 3 OFF - microphone, LOCAL switch 3 ON - stereo line in.
1
2
Connect the microphone (or stereo line input) plug into the REMOTE module microphone socket.
(Note: Ensure that the setting of switch 3 on the LOCAL module matches the input to this socket:
OFF - microphone; ON – stereo line input)
Connect the speaker plug to the REMOTE module speaker socket.
Note: When the REMOTE module is rack mounted, the audio connections must be made
after the module has been fixed in place. Access is required to the rear and above the rack.
Remember to remove the audio connections before attempting to slide out the REMOTE
module.

4. Operation
4.1 Power and activity indicators
On the front panel of both modules are small recessed
indicators which provide confirmation of power and activity,
as follows:
•
•
•
Constant red – power applied no communication
activity.
Flickering red - power applied, mouse or keyboard
activity occurring.
Slow flashing red – module is in flash upgrade
mode.
Note: Both modules contain internal automatic cut-out fuses to protect against power surges. To reset, remove
power (or, for the LOCAL module, the keyboard connection) from the module for one second and then
reconnect.
General Use
In use, the Extender C5 modules should be transparent - the system and its peripherals should operate exactly
as normal, the only difference being that they are now up to 300 metres apart.
In some installations, you may see some ‘shadows’ to the right of high contrast screen characters. This can be
caused by an incorrectly selected sharpness setting and it may be necessary to make adjustments to correct
this. Please see ‘Image controls - sharpness and brightness’ in the ‘Special configuration’ section.
4.2 Locking and unlocking the system
In situations where the computer system (and the LOCAL module) can be locked away the Extender C5 set
offers a viable security system to deter unauthorised use. Once a password has been set, a simple key
sequence allows the system to be quickly and securely detached from its peripherals. Only the correct password
will reconnect the remote and local modules.
To lock the system
1
First set a password. For further details, please refer to
section 5.4 ’Password setting.’
2
Simultaneously press the currently configured hotkeys
(by default, <CTRL> and <SHIFT> along with <L>.
The screen will go blank and the three keyboard indicators will
begin alternately flashing between the ’Num Lock’ and ’Scroll
Lock’, and ’Caps Lock’. This sequence indicates that a password
is required.

To unlock the system
1
Enter the correct password and press <RETURN>.
Note: Passwords are NOT case sensitive.
Note: If an invalid password has been entered and the keyboard indicators are not flashing as described
above press <RETURN> to clear the incorrect attempt.
2
If the correct password is entered, the screen will be restored and normal operation can continue.
To enable the video
Simultaneously press the currently configured hotkeys (by default, <CTRL> and <SHIFT> along with <1>). This
command will be required to restore the video if <CTRL> and <SHIFT> along with <L> is used when no
password has been set.

Simultaneously, press the currently configured hotkeys (by default, <CTRL> and <SHIFT> along with <0>).
5. Special configuration
5.1 Configuration
You can alter the way that the Extender C5 modules operate to suit your requirements. This is done using the
configuration mode and you can affect the following settings:
•
•
Password setting – allows you to lock the remote module to prevent unauthorized system access.
Mouse restoration and settings – allows you to restore mouse operation and also to change the mouse
type.
•
•
•
Image controls - sharpness & brightness – allows you to manually adjust the video image to ensure that
it is crisp and bright.
Skew adjustment – allows you to manually compensate for possible video errors introduced by long,
uneven cable connections.
Miscellaneous functions
5.2 What are hotkeys?
Hotkeys are two normal keyboard keys that, when pressed simultaneously with a third key, signal to the
Extender C5 modules that you are sending a message specifically to them and not to the computer. The hotkeys
are ordinarily <CTRL> and <SHIFT>, while the third key determines what you want the modules to do.
If the standard <CTRL> and <SHIFT> hotkeys are also needed for computer tasks, you can change them for
another combination using switches 2 and 3 on the REMOTE module:
2 OFF
3 OFF
Hotkeys = <CTRL> and <SHIFT> (default setting)
Hotkeys = <ALT> and <SHIFT>
Hotkeys = <CTRL> and <ALT>

5.5 Password override
This mode allows you to override the password that has been set at the REMOTE module and place it into
configuration mode so that a new one may be set. This feature is particularly useful when passwords have
been lost or forgotten.
To override the REMOTE password
1
2
Remove power from the REMOTE module.
With power to the system and LOCAL module still applied, change LOCAL switch 1 to the
ON position.
3
4
Re-apply power to the REMOTE module. The REMOTE module will go directly into
configuration mode so that the old password can be cleared and a new one set.
•
To clear a password: (within configuration mode) Press <P> followed by
<RETURN>and followed by <RETURN>again.
•
You can now enter a new password using the procedure outlined in steps 2 to 5 of
section 5.4 ‘Password setting’, or press <RETURN> to exit configuration mode.
Return LOCAL switch 1 to it’s OFF position.
Note: If switch 1 remains ON, then the REMOTE module will enter configuration mode
whenever it is repowered and will not operate normally.
5.6 Hot plugging and mouse restoration
It is strongly recommended that you switch off the computer system before attempting to connect it via the
Extender C5 modules. However, if this is not possible then you need to ‘hot plug’ the Extender C5 modules
while power is still applied to the system. There is not normally a danger of damage to the system, however,
when mouse communications are interrupted, often they fail to reinitialise when reconnected. Extender C5
modules provide a feature to reinstate mouse communications once the necessary connections have been
made.
There are two main types of data formats used by current PC mice; these are the older ‘PS/2’ format and the
more recent ‘IntelliMouse’ format introduced by Microsoft. These use slightly different data arrangements and it
is important to know which type was being used before you hot-plugged the Extender C5 modules. The previous
setting depends both on the type of mouse and the type of driver as various combinations of PS/2 and
IntelliMouse are possible. Using the incorrect restore function may produce unpredictable results and require the
system to be rebooted.
Which restore setting do I use?
The general rule is that unless both the mouse and the driver are both IntelliMouse compatible then
you need to restore the mouse as ‘PS/2’.
Recognising an IntelliMouse style mouse
The IntelliMouse format was introduced to support, among other features, the scroll wheel function.
If your mouse has a scroll wheel, then it is likely to support the IntelliMouse format. If you have a
Microsoft mouse, then it will usually state that it is an IntelliMouse on its underside label.
LINDY KVM Extender C5 PRO-300 Installation and Use
page 18
Download from Www.Somanuals.com. All Manuals Search And Download.
English Manual
Recognising an IntelliMouse driver
Before hot plugging your Extender C5 (or afterwards using only keyboard control), access the
Windows Control Panel and select either the Mouse option (on Windows NT, 2000 and XP) or the
System option (on Windows 95, 98, ME). Look for the name of the driver, which will usually include
the words PS/2 or IntelliMouse.
To restore mouse operation when hot plugging:
1
2
3
Carefully connect the Extender C5 modules to the system and its keyboard, mouse, monitor,
audio and serial device.
Simultaneously, press the hotkeys (by default CTRL> and <SHIFT>) along with <RETURN>
to enter configuration mode.
Enter the appropriate restore function code:
•
•
PS/2 – press <M> <6> <RETURN>
IntelliMouse – press <M> <7> <RETURN>
4
5
To exit configuration mode, press <RETURN>.
Move the mouse a short distance and check for appropriate onscreen cursor movement. If
the mouse cursor darts erratically around the screen, then cease moving the mouse. This is
an indication that the chosen restore function is incorrect. Try again using the other restore
function.
Note: The restore functions predict the likely mouse resolution settings but may not restore
the exact speed or sensitivity settings that were originally set.
Microsoft and Logitech – specific mouse settings
In certain installations some Logitech mouse drivers may lose the action of the mouse buttons when
used with the standard ‘Microsoft compatible’ signalling protocol used between the modules. To
solve this problem, select the ‘Logitech compatible’ mouse signalling protocol.
To change mouse signalling protocols
1
2
Simultaneously, press the hotkeys (by default, <CTRL> and <SHIFT> along with
<RETURN> to enter configuration mode.
Enter the appropriate protocol code:
•
•
Microsoft compatible – press <M> <3> <RETURN>
Logitech compatible – press <M> <4> <RETURN>
3
To exit configuration mode, press <RETURN>

5.7 Video compensation, Image controls - sharpness and brightness
The Extender C5 incorporates special controls to compensate for losses incurred within long cable links. Using
these controls you can adjust the picture sharpness and brightness to improve your remote picture quality.
The need for image control adjustment is best discovered when viewing high contrast images with vertical
edges, such as black lines on a white background. When doing so, if you notice that the screen image is ‘fuzzy’
or ‘dark’ then the image controls may be able to solve this condition.
Note: If the high contrast images exhibit shadows with separate colours, then there may be a skew problem
which requires a different image adjustment - see the ‘Skew adjustment’ section for details.
To display a suitable high contrast image
The best way to clearly view the effects of compensation is to display
a high contrast image, with vertical edges, on the screen.
•
Open a word processor, type the capital letter ‘H’, or ‘M’ and
increase the point size to 72 or higher. For best results, the
background should be white and the character should be black.
A BLACK shadow on the right of the character indicates
UNDER compensation.
•
•
A WHITE shadow on the right of the character indicates OVER
compensation.
To use the image controls
1. Simultaneously, press the hotkeys (by default, <CTRL> and <SHIFT> along with <RETURN>) to enter
configuration mode.
The three keyboard indicators (‘Num Lock’, ‘Caps Lock’ and ‘Scroll Lock’) will now begin to flash in
sequence. The speed of the sequence indicates the level of the sharpness adjustment currently applied: the
slower the rate, the lower the level of sharpness being applied.
2. While viewing the displayed high contrast screen image, use the following keys to adjust the controls:
Sharpness:
User CURSOR UP and DOWN for fine
adjustment, and PAGE UP and DOWN for coarse
adjustment.
There are 255 sharpness levels (one coarse step
jumps 10 levels).
To autoset sharpness: Press <F> <2> <RETURN>
to make the module calculate and apply an
automatic compensation level - you can use this
as a starting point for your fine tuning.
Note: If the monitor goes blank and switches off
(due to oversetting the sharpness adjustment)
press the <HOME> key to restore.
Brightness: User CURSOR LEFT and RIGHT for adjustment.
There are 255 brightness levels.
3. When no shadows are visible and the displayed images have crisp edges, press <RETURN> to exit
configuration mode and permanently save all settings. The new compensation setting will be stored, even
when power is removed or if a complete reset is initiated. The setting should not require further changes
unless the cabling arrangement is altered.

English Manual
If the image controls cannot provide a crisp image
If, after adjusting the image controls, the screen image remains fuzzy or has
coloured shadows you may need to use the Skew adjustment feature.
Please see the next section for details.
5.8 The Skew Compensation Adjustment
The twisted pair cabling supported by the Extender C5 set
(category 5, or higher) consists of four pairs of cables. Three
of these pairs are used by the modules to convey red, green
and blue video signals to the remote video monitor. Due to
the slight difference in twist rate between these three pairs,
the red, green and blue video signals may not arrive at the
monitor together. This is visible as separate colour shadows
on high contrast screen images. This effect is particularly
apparent when using higher screen resolutions and some
types of category 6 and STP cables and in such instances, if
possible, we recommend you use CAT5e UTP cable.
However, the Extender C5 provides internal skew adjustment that can help to rectify the situation. The skew
adjustment works by delaying or advancing the timing of any of the red, green or blue colour signals so that they
are all delivered to the monitor at precisely the same time. For best results a test pattern is provided and this
should be displayed when using skew adjustment.
To use skew adjustment
1
Insert the supplied Installation CD-ROM into the CD
player of the computer.
2
Within Windows, use the My Computer option (usually
available as a desktop icon or within the Start menu) to
view the contents of the CD-ROM. Double-click the
Skew entry to display the standard test pattern. If
necessary maximise the application window so that the
image fills the screen.
The screen will show a series of fine red, green and blue
crosses which should all be in line, vertically and
horizontally. Skew affects the horizontal placement of
the colours and using this pattern it is much easier to
discover which, if any, colours are being adversely
affected by the twisted pair cable run.
3
Simultaneously, press the hotkeys (by default, <CTRL> and
<SHIFT> along with <RETURN>) to enter configuration mode.
The three keyboard indicators (‘Num Lock’, ‘Caps Lock’ and ‘Scroll
Lock’) will now begin to flash in sequence.

6. Flash upgrade procedure
As part of the continual development and improvement process across the range of LINDY products, software
upgrades are occasionally made available. The LOCAL and REMOTE modules both contain internal flash
memory and LINDY’s unique keyboard-link upgrade technique allows you to utilise software upgrades in a
straightforward manner.
Note: It is important to upgrade both the LOCAL and REMOTE modules together so that they are both running
the same new version of software.
Note: To upgrade the REMOTE module, a special keyboard connection cable is required. This cable must have
6pin mini-DIN male to 6pin mini-DIN male plugs with all lines connected - this is a common cable used with KVM
switches.
Do a flash upgrade ONLY when you experience problems!
To perform a flash memory upgrade, you need to perform the following stages:
•
•
•
•
•
Get the upgrade files from the LINDY technical support team
Create a startup diskette and copy the files to it
Reconfigure the LOCAL module connections and begin
Reconfigure the REMOTE module connections and begin
Return all connections to their usual states
6.1 Get the upgrade files from LINDY Technical Support
Please contact the LINDY Support team in your country by email, telephone or contact form from the LINDY
Decompress the file you have received from LINDY. Depending on the chosen option, there will be collection of
suitable files.
As a minimum, there should be the following files:
AUTOEXEC.BAT – directs the computer to run the upgrade programs.
XKVMV2.EXE – this is the upgrade program that automatically determines which module is
connected and sends the appropriate firmware file.
XKVM.DAT – this file contains information about firmware versions and is used by the
XKVMV2.EXE to select the appropriate one.
X2GDLxxx.HEX, X2SLLxxx.HEX, X2STLxxx.HEX – these are the firmware files for the LOCAL
module.
X2GDRxxx.HEX, X2SLRxxx.HEX, X2STRxxx.HEX – these are the firmware files for the REMOTE
module.
Where xxx is the upgrade version number.
6.2 Create a startup disk
For this stage you will need a blank 3½’’ floppy diskette that is either blank or has existing contents that are no
longer required. Depending on your operating system, use one of the following to create a startup disk:

7. Troubleshooting
If you experience problems when installing or using the Extender C5 modules please check through this section
for a possible solution.
Video image at the REMOTE module is distorted or shadows appear to the right of displayed objects.
Adjustments are required to compensate for the length of the twisted pair cable being used. If video problems
persist:
•
Please refer to ‘Image controls - sharpness and brightness’ section in the ‘Special
Configuration’ chapter.
•
If the overall video image is ‘fuzzy’ and/or has coloured shadows you may need to use the optional C5
Series Skew adjustments. This procedure allows you to finely tune the red, green and blue video signal
timings to overcome most colour separation problems. Please refer to the ‘Skew adjustment’ section in
the ‘Special Configuration’ chapter.
•
If possible try using Cat5/5e UTP cable. There is no particular advantage in using higher specification
Category 6 cables. On the contrary it may even result in unacceptable video quality if you use a)
Category 6 and b) shielded cable.
No video image is received at the REMOTE module
•
Check that the power/activity indicators are lit on the LOCAL and REMOTE modules - if they are not,
then there is a power problem. The LOCAL module gains its power either from the computer’s keyboard
socket or by using an optional power supply. When keys are pressed or the mouse is moved, check that
the indicators flicker – if they do not then there could be a twisted pair link problem or a problem with
one of the modules.
•
Check that the Category 5 (or higher) cable is wired correctly as per the diagram in the section 5.8
‘Skew Compensation’.
•
•
If possible, try using an alternative twisted pair connection between the modules.
If the sharpness control is set too high, the monitor may not be able to display a picture. Try reinstating
the factory default sharpness settings. Please refer to the ‘Image controls - sharpness and brightness’
section in the ‘Special Configuration’ chapter.
•
Temporarily disconnect the video link to the LOCAL module, connect a monitor directly to the computer
video port and check for a correct video image output.
The keyboard indicators are flashing between the Caps Lock and the Num Lock/Scroll Lock and the
computer does not respond to any keyboard or mouse inputs.
•
The modules are currently locked and require a valid password to be entered. Please refer to the
section ‘Locking and unlocking the system’ for details.
Power is applied via the power supply but REMOTE module operation has stopped.
•
Each module has an internal automatic cut-out fuse to protect against power surges. To reset, remove
power from the module for one second and then reconnect.
The on-screen mouse pointer does not respond to mouse movements
•
The mouse connection may have been interrupted. Either, reboot the system and re-power the
REMOTE module power supply, or try using the mouse restoration command. Please refer
to section 5.6 ‘Hot plugging and mouse restoration.’

Sound from the microphone cannot be heard or is very quiet
•
Check the setting of LOCAL switch 3 – if a microphone is connected at the REMOTE module, the switch
should be set to OFF.
Sound input from the stereo line input is distorted and only one channel is working
•
Check the setting of LOCAL switch 3 – if a stereo line input is connected at the REMOTE module, the
switch should be set to ON.
