About This Manual
1 About This Manual
1.1 Scope
This manual describes how to install your KVM Extender, how to operate it
and how to perform trouble shooting.
1.2 Validity
This manual is valid for all devices listed on the front page. The product
code is printed on the base of the devices.
1.3 Cautions and Notes
The following symbols are used in this manual:
This symbol indicates an important operating instruction that should be
followed to avoid any potential damage to hardware or property, loss of
data, or personal injury.
This symbol indicates important information to help you make the best use
of this product.
This symbol indicates best practice information to show recommended
and optimal ways to use this product in an efficient way.
To ensure reliable and safe long-term operation of your KVM Extender
please note the following guidelines:
Installation
Only use in dry, indoor environments.
The KVM Extender and the power supply units can get warm. Do not
situate them in an enclosed space without any airflow.
Do not place the power supply directly on top of the device.
Do not obscure ventilation holes.
Only use power supplies originally supplied with the product or
manufacturer-approved replacements. Do not use a power supply if it
appears to be defective or has a damaged chassis.
Connect all power supplies to grounded outlets. In each case, ensure
that the ground connection is maintained from the outlet socket
through to the power supply's AC power input.
Do not connect the link interface to any other equipment, particularly
network or telecommunications equipment.
Take any required ESD precautions.
In order to disconnect the device completely from the electric circuit, all
power cables have to be removed.
Repair
Do not attempt to open or repair a power supply unit.
Do not attempt to open or repair the KVM Extender. There are no
user serviceable parts inside.
Please contact your dealer or manufacturer if there is a fault.
The KVM Extender is used to increase the distance between a source
(computer, CPU) and its console (keyboard, mouse, and other peripheral
devices).
The KVM Extender is designed for use with Cat X (Twisted Pair)
interconnect cables or fiber interconnect cables.
The KVM Extender with Cat X interconnect cables is unsuitable for
connection between buildings where a fiber optic based product should be
used instead.
The KVM Extender with fiber interconnect cables can also be used with
applications in environments which are difficult in electromagnetical
aspects. Electromagnetical interference can limit the maximum distance
und reliability.
The KVM Extender consists of at least one CPU module and one
CON module. The various modules are summarized respectively in a
vario chassis (2-fold, 4-fold or 6-fold) at CPU site and CON site (CPU and
CON unit).
The CPU module is connected directly to the source (computer, CPU)
using the supplied cables.
The CON module is connected to the console (monitor, keyboard and
mouse).
The CPU Unit and the CON modules communicate with each other
through the interconnect cables.

See Chapter 4.3, Page 46 for installation examples.
Part numbers for Connections via Cat X or Fiber Cable
All mentioned devices are available in the following versions:
Connection via Cat X cable (x = "C")
Connection via Single-mode fiber cable (x = "S")
High speed connection (3.125 Gbit/s) via Single-mode fiber cable
(x = "X")
Fiber devices can be used with Multi-mode and Single-mode cables (see
Chapter 7.2.2, Page 68).
Part numbers for CPU Unit and CON Unit
The part numbers for the CPU Unit and the CON Unit can be derived from
the part number of the complete device.
CPU Unit: L481
CON Unit: R481
All devices of the K481 series are technically compatible to the devices of
the K474 and K477 series.

for this reason an installation in closed rooms without air circulation is not
allowed. Please note that you will need at least 0.5 U (height unit) for the
ventilation above the extenders, if you mount them into racks.

3.7.5 Status Upgrade Module USB 2.0
The upgrade module USB 2.0 is fitted with a multi color LED on both sides
for overall status indication and with two further LEDs on the back side for
indication of the connection status.
First time users are recommended to setup the system with the CPU Unit
and the CON Unit in the same room as a test setup. This will allow you to
identify and solve any cabling problems, and experiment with your system
more conveniently.
Please verify that interconnect cables, interfaces, and handling of the
4.2.1 KVM Extender Setup
devices comply with the requirements (see Chapter 7, Page 60).
1. Switch off all devices.
CON Unit Installation
2. Connect your monitor(s), keyboard and mouse to the CON Unit.
3. Connect the CON Unit with the interconnect cable(s).
4. Connect the 5VDC power supply to the CON Unit.
CPU Unit Installation
5. Connect the source (computer, CPU) with the supplied cables to the
CPU Unit. Please ensure the cables are not strained.
6. Connect the CPU Unit to the interconnect cable(s).
7. Connect the 5VDC power supply to the CPU Unit.
8. Power up the system.
To power up the system, the following sequence is recommended:
Monitor – CON Unit – CPU Unit – source.
The basic module with VGA / DVI-I input is connected as mentioned
above. For a complete and detailed description of the setup and
configuration of the VGA option, see the manual of the Media- / DVIConverter K238-5V (Download
).
