2 Safety Instructions
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.

3.1 Application
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.

Draco KVM Extender
3.2 System Overview
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.

Operation
6.2 Parallel Operation of redundant CPU Units
CPU Units with a redundant connectors for interconnect cables offer the
possibility for a competing control by two connected CON Units.
Taking over control is performed via keyboard and/or mouse. The release
timer function determines the release time of the input devices at one of
the CON Units after that control can be taken over from the second CON
Unit.
In order to configure a redundant CPU Unit for the operation with two
parallely controlling CON Units, proceed as follows:
1. Connect a redundant CPU Unit to any source (computer, CPU) by
using a mini USB connection.
2. Open the file "Config.txt" that is located on the appearing flash drive
of the extender.
3. In order to activate the function of taking over control by keyboard,
write the parameter KBDCON into the second line of the file.
In order to activate the function of taking over control by mouse, write
the parameter MOUCON into the second line of the file.
In order to activate the function of taking over control by keyboard and
mouse, write the parameters in the second and third line with one
parameter per line.
4. Activate the release timer by writing the parameter RELEASETIME=n
into the next free line. The variable "n" defines the time in seconds
and has to be replaced by the numbers 0 to 9 (e.g.
RELEASETIME=5).
If this parameter is not activated at all, the release time is set to
10 seconds by default.
5. Save your changes.
6. Reboot the CPU Unit.

7.1.10 Analog Audio Interface
The analog audio option supports a bidirectional stereo audio
transmission, in nearly CD quality.
The audio interface is a 'line level' interface and it is designed to transmit
the signals of a sound card (or another 'line level' device) as well as to
allow the connection of active speakers to the CON Unit.
Stereo audio can be transmitted bidirectionally at the same time.
Connection of a microphone:
Connect the microphone to the 'audio' input of the CON Unit. There are
two ways to establish this connection:
The output of the CPU Unit is connected with the microphone input of
the sound card (red). Adjust the sound card to provide an additional
amplification (20 dB).
The output of the CPU Unit is connected to the audio input of the
sound card (blue). Choose this connection if the microphone has its
own pre-amplifier.
The CON Unit can do the pre-amplification of the microphone as well.
Open the CON Unit, locate the 'MIC' jumper on the audio board and close
the pins.

7.2.1 Cat X
A point-to-point connection is required. Operation with several patch fields
is possible. Routing over an active network component, such as an
Ethernet Hub, Router or Matrix, is not allowed.
Avoid routing Cat X cables along power cables.
If the site has 3-phase AC power, try to ensure that CPU Unit and
CON Unit are on the same phase.
To maintain regulatory EMC compliance, correctly installed shielded Cat X
cable must be used throughout the interconnection link.
To maintain regulatory EMC compliance, all Cat X cables need to carry
ferrites on both cable ends close to the device.
Type of Interconnect Cable
The KVM Extender requires interconnect cabling specified for Gigabit
Ethernet (1000BASE-T). The use of solid-core (AWG24), shielded, Cat 5e
(or better) is recommended.
Cat X Solid-Core Cable
AWG24
S/UTP (Cat 5e) cable according to EIA/TIA568-B. Four pairs of wires AWG24.
Connection according to EIA/TIA-568-B
(1000BASE-T).
Cat X Patch Cable
AWG26/8
S/UTP (Cat 5e) cable according to EIA/TIA568-B. Four pairs of wires AWG26/8.
Connection according to EIA/TIA-568-B
(1000BASE-T).
The use of flexible cables (patch cables) type AWG26/8 is possible,
however the maximum possible extension distance is halved.

7.3.1 USB-HID Devices
The KVM Extender will support most USB-HID devices, including the vast
majority of keyboards and mice currently on the market. Many other kinds
of HID devices such as bar-code scanners and touch screens may also be
compatible
It is not possible to guarantee support for all available USB-HID devices.
In certain cases, custom firmware may be required.
USB-HID (and other) devices that are not supported as standard will
normally operate with our devices featuring transparent USB support.
Please note that concurrent operation of more than two USB-HID devices
is not possible even if you use a USB hub.
