Rev. : 02/09/2012 1
Welcome to the THOR Family!
Thank you for purchasing a THOR Small Switch! We appreciate your business, and we think
you’ll appreciate the many ways that your THOR system will save you money, time, and
effort.
The THOR Small Switch offers three fundamental uses:
• As a Multiplex Repeater: the DVI signals (+optional audio) coming from a signal
source are equalized and distributed on up to 7 equivalent outputs. A control is not
necessary. Distributed display systems can be realized (Digital Signage).
• As an 8-port Crosspoint Switch: each port can be switched optionally as an input or
output. You can, for example, switch and distribute the signals from 3 signal
sources on up to 5 displays (allowing simultaneous presentations on several
displays). Alternatively, signals coming from 7 signal sources can be switched in
turn to a single display. The changeover can be triggered remotely using the serial
interface (RS232) and/or by a push-button at the device.
• As a 7-port KVM Switch: up to 7 Single-head ports (a “Single-head” extender
system supports 1x monitor, 1x keyboard, 1x mouse) or up to 3 Dual-head ports (a
Dual-head extender system supports 2x monitor, 1x keyboard, 1x mouse). The
changeover can be triggered remotely using the serial interface (RS232) and/or by a
push-button at the device.
Cascade multiple devices in two stages for all applications to give up to 49/1 connections.
The THOR Small Switch has the advantage that it can be positioned up to 140m away from
both your signal source and display device. This becomes possible by using the proven
THOR Extender technology for the transmission of DVI- Monitor and USB-Keyboard and
Mouse signals over CATx- cable.
The operation of a THOR Small Switch always requires at least one Local Unit and up to
seven Remote Units from the THOR Extenders range.

Wherever long distances cause problems for remotely locating and switching a monitor
(keyboard/mouse) signal, e.g. airports, industrial plants, call centers or in distributed
computer centers, the THOR Small Switch is the best solution. Its flexibility allows it to
tackle many tasks.
In addition, there are 4 Media Extenders (DVI + optional audio) and 8 KVM- Extenders
(DVI+USB keyboard mouse + optional audio) available. The transmission of the signals
requires connecting CATx cable.
This manual will tell you all about your new THOR Small Switch, including how to install,
operate and troubleshoot it. For an introduction to the Converter, see Chapter 2.

2. Overview
2.1 Introduction
The THOR Small Switch can be set up in three configurations:
• As a Multiplex Repeater: - the DVI signals (+optional audio) coming from a
signal source are equalized and distributed on up to 7 equivalent outputs. A control
is not necessary. Distributed display systems can be realized (digital signage).
There are three operating modes: 1 link (1 source to 7 screens), 2 links (1 source to
3 screens each) and 4 links (1 source to 1 screen each): a pure length booster.
• As an 8-port Crosspoint Switch: each port can be switched optionally as an input
or output so you can, for example, switch and distribute the signals from 3 signal
sources on up to 5 displays (allowing simultaneous presentations on several
displays). Alternatively, signals coming from 7 signal sources can be switched in
turn to a display. The changeover can be triggered remotely using the serial
interface (RS232) and/or by a push-button at the device.
• As a 7-port KVM Switch: up to 7 Single-head switches (a “Single-head” extender
system supports 1x monitor, 1x keyboard, 1x mouse) or up to 3 Dual-head switches
(a Dual-head extender system supports 2x monitor, 1x keyboard, 1x mouse). The
changeover can be triggered remotely using the serial interface (RS232) and/or by a
push-button at the device.
A Multiplex Repeater system consists of a THOR Small Switch and one or more
Local/Remote Units. Optionally, THOR Small Switches can be cascaded in a maximum of
two stages (master/slave). The THOR Small Switch and the Local/ Remote Units are attached
by CATx cables.
The operation of a THOR Small Switch always requires (at least) one Local Unit of a THOR
Extender and up to seven Remote Units of THOR Extenders.

2.4 Features
All members of the THOR Small Switch Series offer the following features:
• Support for DVI-D Graphic cards (all devices)
• Support for USB-Keyboard and USB-Mouse (KVM-Extender)
THOR KVM devices with USB- connectors support the extension of
keyboard and mouse ONLY; use with other HID devices (Human Interface
Device) such as touch screens, graphics tablets, barcode readers or similar
may be successful – but there is no guarantee for this! The THOR KVM is
NOT suitable for use with other USB- devices such as scanners, web- cams,
data sticks etc.
THOR KVM devices support only two devices simultaneously – keyboard
and mouse or keyboard and touch-screen, etc. but not e.g. keyboard, mouse
and touch-screen simultaneously. You can extend a USB hub but this does
not raise the number of supported devices.

2.6 Compatibility
Interface Compatibility
• Digital Video (DVI-D): Digital Video standard, installed by Digital Display Working
Group (www.ddwg.org) R, G, B, CLOCK in a data stream with up to 3x 1.6 Gbit/sec.
Signals are TMDS Level.
• USB Keyboard: Compatible with all standard keyboards. Certain keyboards with
enhanced features may also be supported with custom firmware. Keyboards with built-in
hub are also supported – but there are never more than two HID devices supported.
• USB Mouse: Compatible with all standard 2-button, 3-button and scroll-wheel mice.
The THOR KVM devices with USB connectors supports the extension of
keyboard and mouse ONLY; use with other HID devices (Human Interface
Device) such as touch screens, graphics tablets, barcode readers or similar
may be successful – but there is no guarantee for this! The THOR KVM is
NOT suitable for use with other USB- devices such as scanners, web- cams,
data sticks etc.
The THOR KVM supports only two devices simultaneously – keyboard and
mouse or keyboard and touch-screen, etc. but not e.g. keyboard, mouse and
touch-screen simultaneously. You can extend a USB hub but this does not
raise the number of supported devices.
• Fiber / CATx devices: It is possible, to equip a THOR fiber device with fiber and CATx
GBIC’s. So it is possible to switch both topologies within a single device.
It is NOT possible to connect devices from different
topologies (CATx and fiber) and run them together. Even
though the signals are routed through – the data format is
incompatible.

2.7 How to Use This Guide
This guide describes the installation and configuration of the THOR Small Switch. Although
the connection and operation of the system is relatively straightforward, you should consider
the following before getting started:
Connection & Compatibility
The individual THOR Small Switch components consist of:
• THOR Small Switch for CATx: includes the device and power supply.
• THOR KVM/ Media Local Unit: includes the device, power supply and all the cables
required to connect the THOR KVM/ Media Local Unit to your CPU/ Signal source.
• THOR KVM/ Media Remote Unit: includes the device and power supply
Please see also Package Contents (Page 25).
For information about connection and installation, see page 28.
DDC Information
Normally it is not necessary to make any adjustments to the DVXi- Extender. However, in
some circumstances, it may be necessary to redefine the source of DDC Information for the
CPU. By default, the DVXi/ET KVM-Extender uses its own internal DDC table. If this
setting does not satisfy your requirements, the DDC table can either be switched to the locally
attached screen or could be downloaded from a remotely located screen and stored in the
internal DDC table.
To modify the DDC-Setup, see DDC / color depth (page 62).
Selecting the moment of switching to the next frame
The transmission of screen data in not synchronous to the screen change of the graphic card.
Normally, the transmission is terminated during displaying a frame on the screen. If the
device switches to the new frame during the displaying period of the old frame (somewhere
on the screen), it’s possible that you can see horizontal screen breaks in the moment of
switching (default). On the other hand the device must idle until the actual frame is displayed
completely (until VSYNC) -> the number of frames per second transmitted sync.
Selection of Color reduction for transfer speed
You can select whether 24 Bit colors (=full color depth) are always transmitted or whether the
compression algorithm automatically switches between 16 and 24 Bit colors to accelerate the
data transfer (default). Normally the difference between 24 Bit and 16 Bit is not recognizable
but under some special circumstances e.g. in photo processing installations there might be
disturbing color aberrations. However, the automatic color switching enhances the count of
frames transmitted per second; fixed 24 Bit color depth gives smooth color grades under all
circumstances. Please select the best mode for you. To modify the color depth, see DDC/
color depth (page 62).

3.2 Cable Connection Requirements
To connect the THOR Media Local Unit to your CPU/signal source you will need (Please
ensure that the connection is tension-free!):
DVI: Connect the supplied DVI- cable 1.8m (DVI-I male to DVI-I male) to your CPU
(KVM- Switch, DVI- signal source, etc.).
To connect the THOR KVM Local Unit to your CPU/signal source you will need (Please
ensure that the connection is tension-free!):
DVI: Connect the supplied DVI-cable 1.8m (DVI-I male to DVI-I male) to your CPU
(KVM- Switch, DVI- signal source, etc.).
USB: Connect the supplied USB- cable 1.8m (USB Type A to USB Type B) to your CPU
(KVM- Switch, DVI- signal source, etc.).
To connect the THOR KVM Local Unit with serial/audio you will additionally need (Please
ensure that the connection is tension-free!):
Serial cable: Connect the supplied serial cable to your CPU/signal source.
Audio cable: Connect the supplied audio cable to your CPU.
CATx- cable: Recommended cable: S/UTP (Cat5) according EIA/TIA 56A, TSB 36 or
Digital STP 17-03170. Four pairs AWG 24. Wiring according EIA/TIA 568A (10BaseT). Use
of cables from a higher category (Cat5e, Cat6, and Cat7) is possible.
The use of unshielded CATx- cable is possible; because of the higher electromagnetic
noise/sensitivity, the device class may not be reached.
You may use flexible cables (patch cable) type AWG26/8 but because of the
higher loss of the stranded cables, the maximum extension distance is
reduced to approximately half the value of solid cables.
A point-to-point connection is required. You may use one or more patch
panels in the line. Do not connect the CATx- link interface (RJ45) to any
other products, especially telecommunications or network equipment.
THOR-SSM
Rev. : 02/09/2012
29
• Fiber Cable: Two strands of fiber are required for single-head devices, four strands for
Dual-head devices.
Please note that the allowed distance will depend on device type AND on
used fiber type.
• Recommended cables:
Multimode type 50/125µ allowed distance app. 400m (1,300ft)
Multimode type 62.5/125µ allowed distance app. 200m (650ft)
Singlemode type 9/125µ allowed distance app. 10km (32,750ft)
A point to point connection is required. Having one or more patch panels
in the line is possible and allowed. Not allowed is a connection from the
Fiber link interface (LC) to any other products, especially
telecommunications or network equipment.
Our experiences show that Singlemode devices regularly work well on
Multimode Fibers where vice versa it will never do. In addition, we found
that Singlemode devices on Multimode fibers may extend the allowed
distance on Multimode fibers to twice the regular length. Anyway this
cannot be guaranteed and must be evaluated by the end-user at his own
expense.
Power Supply: Connect the supplied 5V/DC power supplies to the Plug terminal on the rear
of THOR Local Unit, THOR Small Switch or THOR Remote Unit.
