DVXI/ET-XX KVM-EXTENDER

Welcome to the DVXi/ET KVM-Extender Family!

Thank you for purchasing a DVXi/ET KVM-Extender! We appreciate your business, and we
think you’ll appreciate the many ways that your enhanced RGB Graphic system will save you
money, time, and effort.

That’s because our DVXi/ET KVM-Extender is all about breaking away from the traditional
model of attaching a new display to DVI graphic source. Using the DVXi/ET KVM­Extender, you can remotely locate monitor, keyboard and mouse up to 140m away from your
CPU.

Wherever long distances are usual, e.g. airports, industrial plants, call- centres or in
distributed computer centres, the DVXi/ET KVM-Extender is the best way, to solve all
problems in remotely locating your console. 8 different types are available: Singlehead and
Dualhead devices for PS2 keyboard/mouse and Singlehead and Dualhead devices for USB
keyboard/mouse.

Audio/serial Options are also available for each device.
This manual will tell you all about your new DVXi/ET KVM-Extender, including how to

install, operate, and troubleshoot it. For an introduction to the Converter, see Chapter 2. The

OVERVIEW

2. Overview

2.1 Introduction

A KVM Extender is used, to extend the distance between a CPU and his Keyboard / Monitor
/ Mouse considerably. In addition they are irrecoverable in installations in electromagnetic
hazardous environments (EMI). Normal Keyboard-/ Monitor-/ Mouse extender cables (and
Extender using traditional cables) cannot go so far and EMI interferences may reduce the
maximum distance and/or reliability. Using a DVXi/ET Extender system, these limitations
are past. Remain your CPU in a secure rack cabinet or data centre while accessing from a
140m (CATx) up to 10.000m (Singlemode) remotely located place.

A basic KVM extension system comprises a Local unit and a Remote unit. The Local unit
connects directly to the CPU (or a KVM switch system) using the supplied cable(s). The user
console (keyboard, mouse and monitor) attaches to the Remote unit. The Remote and Local
units communicate video and data information along the interconnecting cable. Local units
offer dual access, allowing the connection of a second user console close to the computer.

OVERVIEW

2.7 How to Use This Guide

This guide describes the installation and configuration of the DVXi/ET – Extender Series.
Although the connection and operation of the system is relatively straightforward, you should
consider the following before getting started:

Connection & Compatibility

If you have purchased an Extender Kit, this will contain all the cables required to connect the
Local unit to your PC or KVM switch. Please see also: Package Contents (page 16)

Devices with PS2 connectors are NOT compatible to devices with USB connectors.
For information about connection and installation, see Installation, page 16.

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 remotely located screen and stored in the
internal DDC table.

To modify the DDC-Setup, see Service Setup (page 32).

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 sinks.

To modify the switching behaviour, see Service Setup (page 32).

Selection of Color reduction for transfer acceleration

You can select, whether always 24 Bit colors (=full color depth) are 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 abberations. 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 to you choice the better mode.

To modify the color depth, see Service Setup (page 32).

DVXI/ET-XX KVM-EXTENDER

3.2 Interconnection Cable Requirements

To connect the Local and Remote units you will need:

• DVI, PS2-Keyboard, and PS2-Mouse: Connect the supplied KVM CPU cable set to

your CPU (KVM - Switch, etc.). Please ensure that the connection is tension-free!
Devices K461-1W, K461-2W, K461-SA and K461-DA

• DVI, USB-Keyboard, USB-Mouse: Connect the supplied DVI-D cable (DVI-D to

DVI-D) and the USB-cable (USB-A to USB-B) to your CPU. Please ensure that the
connection is tension-free! Devices K461-1U, K461-2U, K461-SU and K461-DU

• DVI: Connect the supplied DVI CPU cable set to your CPU (KVM - Switch, etc.).

Please ensure that the connection is tension-free! Devices K461-2W, K461-2U, K461­DA and K461-DU

• serial/audio: Connect the supplied serial/audio cable set to your CPU (8pin miniDIN

male to serial DB9-male/female and 2c 3.5mm audio).

• Serial: Connect the supplied serial cable to your CPU.

• Audio: 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. connection according EIA/TIA 568A
(10BaseT). Use of cables from a higher category (Cat5e, Cat6, 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.

18

The use of flexible Cables (Patch cable) Type AWG26/8 is possible.
Because of the higher loss of the stranded cables, the maximum distance is
reduced to app. half the value of solid cables.

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 CATx
link interface (RJ45) to any other products, especially telecommunications

or network equipment.

INSTALLATION

• Fiber Cable: Two strands of fiber are required for singlehead devices, four strands for

Dualhead devices.

Please note, that the allowed distance will depend on device type AND on
used fiber type.

• Recommended cables:

K462-xx: Multimode type 50/125µ allowed distance app. 400m (1,300ft)
K462-xx: Multimode type 62.5/125µ allowed distance app. 200m (650ft)
K463-xx: 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 both local and remote units.

To install your DVXi/ET – Extender system:

1. Switch off all devices.

2. Connect your keyboard, monitor(s) and mouse to the Remote unit (depending on device

type). Please ensure, to not swap Mouse- and Keyboard connector. The (PS2-) Keyboard
connector is purple and the (PS2-) Mouse connector is green.

3. Using the supplied CPU KVM cable(s), connect the keyboard, monitor(s) and mouse

connectors on the computer (or KVM switch). Please ensure, to not swap Mouse- and
Keyboard connector. The (PS2-) Keyboard connector is purple and the (PS2-) Mouse
connector is green.

4. Connect the interconnect cable to the INTERCONNECT socket(s)

5. Connect the 5V power supply to power the unit.

Only use the power supply originally supplied with this
equipment or a manufacturer-approved replacement.

6. For a dual access system, connect the monitor for the Local console to the appropriate

4. Service Setup

For most applications, you shouldn't need not to make any adjustments to set up your
DVXi/ET KVM -Extender. Under some special circumstances it could be necessary to setup
configuration specials.

For some applications, you may need to open the Local Unit and/or the Remote Unit.
Unscrew the Philips-type screws at both sides at the bottom of the device. Unscrew the UNC
type screws at both sides of the monitor connectors. Carefully displace the lower and upper
shells of the case.

SERVICE SETUP

4.1 Setup at the Local Unit

After unscrewing and opening the upper shell, please place the device in this orientation: with
the CATx/fiber connectors to the right and the electrical connectors to the left.

The main PCB then will look like this:

Use the diagram to locate jumpers.

DDC

You can select, whether the DDC is taken from internal DDC table or from local monitor or
the DDC information could be downloaded from remote monitor and stored into internal
table.

4 Reset DDC Table to factory values

33

DVXI/ET-XX KVM-EXTENDER

Loading the DDC Information from the Remote Monitor into the
internal DDC Table

To load the DDC Information from the Remote Monitor into the internal DDC Table,
please proceed the following steps:

• Power up the CPU, the Local Unit, the Remote (cables to the CPU connected) and the

Monitor

• Pull the Monitor Cable(s) from the Remote Unit (Dualhead devices: BOTH Monitors!)

• Switch ON the Monitor(s) (if switched OFF, Dualhead devices: BOTH Monitors!)

• Plug the Video-Cable of the Remote Monitor(s) into the remote unit (Remote and Local

Unit powered! - Dualhead devices: BOTH Monitors!)

• The DDC Information of the Remote Monitor(s) is read automatically, transferred to the

Local Unit and stored into the DDC-EPROM

• After a successful programming of the DDC EPROM, the ‚Video-OK’ LED at the

Local Unit is blinking rapidly for approx. 1 second

• Done

Selection of Color depth

You can select, whether 16/24Bit AUTOSELECT colors (=64K/16M colors) are transmitted
(default) or 24Bit colors (=16M colors). AUTOSELECT means, that as far as the screen
content allows high data compression, 24Bits are transmitted. When the video data do not
allow to reduce data enough, the colors are automatically reduced to 16Bit. This is auto
selected in each line of the screen picture at any time. This mode makes the best compromise
between speed and color depth.

Please select 24Bit, if you want to have under all circumstances highest colours (but perhaps
with reduced frame rates).

Color depth JP3

16Bit/24Bit AUTOSELECT, color depth depending on
actual screen content (default)

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. On the other hand the device must idle, until the actual frame is displayed
completely (until VSYNC) -> the number of frames per second transmitted sinks.

Moment to switch JP3 behaviour

Switching during HSYNC

Higher framerate but (possibly) horizontal breaks
detectable

Lower framerate no horizontal breaks detectable but
(possibly) stepping pictures

5. Troubleshooting

Monitor

There isn’t a picture.

Check the power supply connection at the local and remote unit. Is the Power (Red
LED) at the Local unit illuminated (see page 31)? If not, the internal power-supply
may be damaged or there may be an internal error.

Check that the INTERCONNECT cable is connected at the Local Unit and the
Remote Unit. Is the Link Status LED illuminated (see page 31)? If not, there may be
a problem with the Interconnection cable:

Are there Errors through data transmission over INTERCONNECT Cable (Cable

too long, too high attenuation or too much EMI interference )? Is the Data Error
LED illuminated or blinking (see page 31)? If yes, check cable length and
environment.

Video Okay LED is dark: CPU does not provide a video signal – Check settings of
the graphic card. Try out, connecting a monitor to the local output, to see, whether
there is a signal or not.

‘Stepping’ pictures on displaying movies

On high resolutions, the amount of data transmitted each second expires the
capability of the data link. Therefore the data have to be reduced before
transmitting. This is done in a first step by a so called RLE (=Run Length
Encoding) algorithm. If this (loss less) compression does not reach the required
amount, frames are dropped: The frame actually transmitted is transmitted
completely even if the graphic card generates a new frame. This new frame is
discarded. Because of this behaviour, the count of frames per second (fps) may be
reduced to a value, where ‘stepping’ pictures are seen.

How to solve the problem: Please use a lower resolution, which is slightly higher
than the resolution of the recorded movie. Please see, that most (actual) movies do
have only a low resolution of approx. 640x480 (NTSC) or 640x512 (PAL) or even
320x256 (VHS). If the monitor provides a higher resolution, it may provide the
scaling of the pictures. The picture quality is the same, if the monitor or the CPU
does the scaling.

How to solve the problem: Set the color depth to 16/24Bit AUTOSELECT. On
moving pictures, the human eye is not able, to see differences between so many
colors. A reduction to 16Bit reduces the amount of data without (visible) effects.

TROUBLESHOOTING

PS2-Keyboard

The PC boots fine with no error messages but the keyboard does not work at all

Wrong cable plugged in, keyboard and mouse cables reversed.
Try a different model of keyboard. If the new keyboard works then original one

may be incompatible
Check that the Interconnection cable is connected at the Local Unit and the Remote

Unit. Is the Link Status LED illuminated (see page 31)?
The other console is active. Claim control by any keyboard action or by pressing

left and right mouse buttons simultaneously.

PS2-Mouse

A mouse cursor appears on the screen, but the mouse does not work

Wrong cable plugged in, keyboard and mouse cables reversed.
Try a different model of mouse
You have connected the Local unit while the CPU was running. Therefore you have

connected first the keyboard cable and then the mouse cable. Disconnect the
keyboard cable and connect it again. Please reboot you CPU if the mouse is still not
running.

The other console is active. Claim control by any keyboard action or by pressing
left and right mouse buttons simultaneously.

The system does not detect a PS/2 mouse, or the application cannot find the mouse.

Wrong cable plugged in, keyboard and mouse cables reversed.
Ensure that the Local Unit is connected to the PC keyboard port to provide power.
You have plugged keyboard and mouse cable to the CPU ports while the CPU was

powered. There you first have plugged the Keyboard cable, then the Mouse cable.
Please unplug and re-plug the keyboard cable. If the mouse still does not work,
please reboot the CPU: The K/M sub electronics are powered by the CPU keyboard
port. If you first plug in the keyboard cable, the circuit tries to find a mouse port. If
it fails, it disables the mouse functionality.

Your USB-keyboard/USB-mouse does not work

Although we tried to design the devices as transparent as possible, we can’t ensure
that all devices are running. Please ask Technical Support for a list of tested
devices.

Your mouse is ‘stepping’ on your screen

On high resolutions, the amount of data transmitted each second expires the
capability of the data link. Therefore the data have to be reduced before
transmitting. This is done in a first step by a so called RLE (=Run Length
Encoding) algorithm. If this (loss less) compression does not reach the required
amount, frames are dropped: Because of this, ‘stepping’ mouse movements are
seen.

How to solve the problem: Please use a lower resolution or use a desktop
background which is better suitable for compression: Avoid photos for background
or horizontally graduated colors – better use monochrome backgrounds. They allow
higher compression -> higher frame rates.

Your mouse is moving like ‘hanging on a rubber band’

This problem derives from different single problems, which accumulate to a delay
between the true mouse movement and displaying the movement of the mouse
pointer on the screen. Depending to our measurements, a delay of approx. 100­150msec are recognized as disturbing.

The total delay comes from (time values are approx. values):

• 5 to 15msec for mouse movement and data transmission to CPU

38

• 50 to 70msec data processing time in the CPU until the changed data

reach the graphic card output connector

• 15 to 45mcec getting the graphic data into the local unit of the

extender system and transmitting to the remote unit (60 to 20fps)

• 10 to 100msec data processing time in the display until the data are

displayed on the screen (where 15msec normally are only reacht by
CRT tubes)

In total there are delay times between 85 and up to 230msec possible, where most
of this delay is NOT caused by the extender system (Extender based delay is 5 to
15msec data transfer to the CPU and 15 to 45msec frame transfer to the remote unit
– in total 20 to 60mesec. Depending to our experiences, even a step from 100msec
delay to 140msec (i.e. by inserting an extender system to a CPU-monitor link) may
cause visible effects.

Please note, that even a monitor directly connected to a CPU has a delay of 70 to
175msec. So (under special conditions) even the bare CPU/monitor link shows this
‘rubber band behaviour’. If you now insert an extender system, the problem may
occur and is (in false) dedicated to the extender system, where it only gives a small
part to the total problem

How to solve the problem: Use a display with a low delay time (NOTE: This is
NOT the reaction time indicated by the manufacturer. This reaction time is only the
time the display needs, to switch a black pixel to get white or vice versa, but not
how long it takes from receiving the data on the connector until they are displayed
on the screen.) Please use a lower resolution or use a desktop background which is
better suitable for compression: Avoid photos for background or horizontally
graduated colors – better use monochrome backgrounds. They allow higher
compression -> higher frame rates. If – and only if the link has frame dropping, a
reduction from 30fps to 60fps saves 17msec and from 20fps to 60fps saves 34msec.

Remote Unit Connectors: 2 x 3.5mm stereo jack socket (Line/Mic In & Line

Out)

Microphone Support: A microphone may be connected to the Remote Unit.

A Pull-up resistor provides bias for condenser micro­phone. Optional microphone amplification to +17dB

Serial Interface - Set Up and Operation

No setting up or user adjustments are required. Please note that on the dual access model, the
serial link is always active Please bear in mind that the Remote Unit’s serial port is wired as
DTE (i.e. the same as that on a PC). To connect a serial printer (or other DTE rather than
DCE device) to the Remote Unit, you will need a Null-Modem (crossover) cable between the
Remote Unit and the printer. A Touch screen may be plugged directly into the Remote Unit.

Please note, that

interconnection (Tx/Rx/GND) only. All connected devices must
support Software Handshake (XON(XOFF)

Dualhead KVM Extender support a 3-wire-

46

APPENDIX C: DEVICES W/ SERIAL/AUDIO OPTION

Serial Interface – Handling Multiple Serial Devices – Singlehead
devices only!!!

The extender’s serial interface transmits/receives six signals (3 signals in each direction).
Normally four of these signals are used for hardware handshaking (in addition to TX & RX).
However, because each handshaking line can support signals up to 19,200 Baud it is possible
to configure the serial interface to handle up to three simple 2-wire (Tx/Rx only) serial links.
To do this you will need to construct a custom breakout cable. Please contact technical
support for further information. Select XON/XOFF software flow control on the printer and
PC.

Audio Interface - Set Up and Operation

The audio interface is line-level and is designed to take the output from a sound card (or other
line-level) source and be connected to a set of powered speakers at the other end of the link.
Stereo audio may be transmitted either way across the link (simultaneously). No set up is
required unless a microphone is connected to the remote unit. Connect up the extender as
follows:

• Take the line-level output from your sound card (green connector) and connect to

‘Line In’ on the extender.

• A set of powered speakers may be connected directly to ‘Line Out’ at the opposite

end of the link.

Audio Interface – Using a Microphone

A microphone may be plugged into the ‘Line In’ connector on the Remote Unit. There are
two ways of setting up a microphone:

• The Local Unit’s ‘Line Out’ connection should normally be wired to the

microphone input (Red) on your sound card. The sound card should then be set up
to provide additional amplification (+20dB). This is the preferred connection
method.

• Alternatively, the Remote Unit itself can provide microphone amplification. To set

this, open up the Remote Unit and locate the jumper labelled ‘MIC’ on the
daughterboard. Connect this jumper across the pins. The Local Unit’s ‘Line Out’

connection should then be wired to ‘Line In’ (Blue) on your sound card.
If your microphone is already amplified, follow the second method but DO NOT install the
amplification jumper in the Remote Unit.

APPENDIX E: LIST OF SUPPORTED USB DEVICES

Appendix E: List of supported USB devices

Although the USB connection’s implementation allows all keyboards and Mice, we can not
guarantee that all available keyboards/mice are running.

The implementation is constructed for “HID” devices. HID is a device class enabling inputs
in a PC. Among others touch screen, graphic tablet, fingerprint sensor are HID devices.

Some devices install additional devices, e.g. to set parameters. Such devices are NOT
supported by our extenders. Please remark additionally that installing more than two devices
is not possible even if you use a USB hub.

The following devices are tested and have been found correct:
