1. Introduction
Thank you for purchasing the LINDY Extender C5 Pro set which allows you to place the controlling keyboard,
video monitor, mouse, audio accessories (and also a serial device) up to 00 metres from a system. The LINDY
Extender C5 Pro 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.
Internal circuitry within the remote module ensures crisp video images by automatically compensating for the
length of the twisted pair cable run.
Throughout this document, the LINDY Extender C5 Pro is
commonly abbre iated to Extender C5

2. Installation
The installation of the Extender C5 set is straightforward and can best be achieved in most cases by
following these stages for each module:
• Check or set the configuration switch settings
• Mount the module
• Connect the cables
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).
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.)
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.)

English Manual
LINDY KVM Extender C5 Pro Installation and Use page 10
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.

English Manual
LINDY KVM Extender C5 Pro Installation and Use page 11
REMOTE Switch 1
OFF: Normal operation.
ON: (Before power is applied) Places the REMOTE module into flash upgrade mode so that the internal
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 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.
OFF Hotkeys = CTRL and SHIFT
3 OFF
OFF Hotkeys = ALT and SHIFT
3 ON
ON Hotkeys = CTRL and ALT
3 OFF
ON Hotkeys disabled
3 ON
REMOTE Switch 4
OFF: Automatic video compensation mode. In this mode circuitry within the REMOTE module will adjust the
video compensation settings automatically at power on to match the length of the cable run (providing
the twisted pair to both modules is connected and both modules are switched on).
ON: Manual video compensation mode. Use this mode to bypass the automatic compensation circuitry if
manual adjustment is required to improve the video quality. Automatic video compensation disabled.
(Please see section 5.7 ‘ ideo compensation.’)

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.
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 rac , therefore, chec 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.
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.
3 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 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.
5 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 K M+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. Attach the supplied KVM+A multi-cable to the 5-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 Blue
Keyboard Purple
Mouse Mid green
Speaker Light green
Microphone Pink (or maroon)

English Manual
LINDY KVM Extender C5 Pro Installation and Use page 14
3.2 Serial cable connection
The Extender C5 set offers the option to attach an RS 3 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 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 00 metres.
1 Insert the connector from the twisted pair cable link into the socket.

3.6 Audio connections
Audio connections are available at the two 3.5” jac soc ets mounted
on the side (same side as the switch ban ) 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 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 soc et:
OFF - microphone; ON – stereo line input)
Connect the speaker plug to the REMOTE module speaker socket.

English Manual
LINDY KVM Extender C5 Pro Installation and Use page 17
Note: When the REMOTE module is rac mounted, the audio connections must be made after the module has
been fixed in place. Access is required to the rear and above the rac . Remember to remove the audio
connections before attempting to slide out the REMOTE module.

English Manual
LINDY KVM Extender C5 Pro Installation and Use page 18
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 eyboard 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 eyboard 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 00 metres apart.
In some installations, you may see some ‘shadows’ to the right of high contrast screen characters. This is
caused by an incorrectly selected video compensation setting. In the majority of cases the automatic video
compensation circuitry will correct such occurrences. However, it may be necessary to manually adjust the video
compensation settings or in extreme cases to install an optional correction module. (See section 5.7 ‘ ideo
compensation.’ )

English Manual
LINDY KVM Extender C5 Pro Installation and Use page 19
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.’
Simultaneously press the currently configured hotkeys
(by default, b and j)along with L.
The screen will go blan and the three eyboard
indicators will begin alternately flashing between the
’Num Loc ’ and ’Scroll Loc ’, and ’Caps Loc ’. This
sequence indicates that a password is required.
To unlock the system
1 Enter the correct password and press f.
Note: Passwords are NOT case sensitive.
Note: If an invalid password has been entered and the eyboard indicators are not flashing as described
above press f to clear the incorrect attempt.
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, b and jalong with 1. This
command will be required to restore the video if b and jalong with L is used when no password
has been set.
To disable the video
Simultaneously, press the currently configured hotkeys (by default, b and j) 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.
• Video compensation – allows you to manually adjust the video compensation settings.
• 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 b and j, while the third key determines what you want the modules to do.
If the standard b and j hotkeys are also needed for computer tasks, you can change them for another
combination using switches and 3 on the REMOTE module:
OFF Hotkeys = b and j (default setting)
3 OFF
OFF Hotkeys = a and j
3 ON
ON Hotkeys = b and a
3 OFF
ON Hotkeys disabled
3 ON
