ServSwitch™ DKM

Welcome to the ServSwitch™ Family!

Thank you for purchasing a ServSwitch™ DKM! We appreciate your business, and we think
you’ll appreciate the many ways that your ServSwitch™ DKM will save you money, time,
and effort.

The ServSwitch™ DKM offers four fundamental uses:

 As a Crosspoint Switch with a maximum of 32 input ports and 16 output ports.

Optionally, in reverse mode, the device supports a maximum of 16 input ports and
32 output ports. Thus, you can, for example, switch and distribute the signals from
multiple signal sources on up to 32 displays (allowing explicitly simultaneous
presentations on several displays). Alternatively, signals coming from up to 32
signal sources can be switched in turn to a single display. The changeover can be
triggered remotely using the remote control (included), the serial interface (RS232)
and/or by the built-in web interface.

 As a KVM Switch with a maximum of 32 CPU ports and 16 Console ports. The

ports can be configured as Single-Head ports (a “Single-Head” extender system
supports 1x monitor, 1x keyboard, 1x mouse), Dual-Head ports (a Dual-Head
extender system supports 2x monitor, 1x keyboard, 1x mouse) or even Quad-Head
ports (a Quad -Head extender system supports 4x monitor, 1x keyboard, 1x mouse).
The changeover can be triggered remotely using the remote control (included), the
serial interface (RS232) and/or by the built-in web interface.

 In KVM Switch Mode CPU Ports and CON Ports can be configured as USB2.0

Ports. This can be done for single Ports as well as for combinations of one Single­Head (Triple-Head-)Port and one USB2.0 Port. In the latter case the respective
consoles will always be switched together with its assigned USB2.0 Port.

 As a special case of the KVM Switch, you can choose the “Control Room” Mode

with 2, 4 or 8 monitors. In “Control Room” Mode, up to 8 CPU’s are permanently
displayed on up to 8 monitors. With a hotkey, you can switch to any of these
monitors for operation.

 In “Teacher/Student” Mode, the teacher can attend up to 31 students.

The ServSwitch™ DKM has the advantage that it can be positioned (CATx version) up to
140m away from both your signal source and display device. This becomes possible by using
the proven ServSwitch™- Extender technology for the transmission of DVI- Monitor and
USB-Keyboard and Mouse signals over CATx cable.

The operation of a ServSwitch™ DKM always requires up to 32 Local Units and up to 16
Remote Units from the ServSwitch™-Extenders range.

Wherever long distances cause problems for remotely locating and switching a monitor
(keyboard/mouse) signal, e.g. airports, industrial plants, call centres or in distributed
computer centres, the ServSwitch™ DKM is the best solution to distribute and switch
monitor (keyboard/mouse) signals. Its flexibility allows it to tackle almost every task.

There are 8 pre-configured ServSwitch™ DKMes for CATx as well as an empty chassis for
individual configuration. 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.

For fibre applications, all switch elements and extenders are also available in multimode or
singlemode versions, requiring the respective cabling.

This manual will tell you all about your new ServSwitch™ DKM, including how to install,

operate and troubleshoot it. For an introduction to the device, see Chapter 2.

2 Overview

2.1 Introduction

The ServSwitch™ DKM can be set up to support four different applications:

 Crosspoint Switch: Maximum configuration (without cascading) of 32 input ports

and 16 output ports. Optionally, in reverse mode, the device supports a maximum
of 16 input ports and 32 output ports.
Set-Up: Local units are installed at up to 32 DVI signal sources. The Crosspoint
Switch may now be installed up to 10 km away from the sources.
The received signals (DVI + optional serial/Audio) can now be switched to the
respective output ports. One input signal may be distributed simultaneously to
several output ports.
From these output ports, the displays (again, up to 10 km away) are controlled via
remote units to be installed at each display. The changeover can be triggered
remotely using the serial interface (RS232) and/or by the built-in web interface.

 KVM Switch: As a KVM Switch the device supports several operation modes:

16 User ports on 32 CPU ports for Single-Head access, 8 User ports on 16 CPU
ports for Dual-Head access or even 4 User ports on 8 CPU ports for Quad-Head
access.
Single-Head/ Dual-Head/ Quad-Head CPUs/ and User ports may also be operated
in mixed mode. In this case, the maximum number of User ports depends on the
detailed configuration.
A maximum of 32 CPUs (up to 10 km away) can be connected to the KVM Switch
via Local units to be installed at each CPU.
The received signals (DVI, Keyboard, Mouse + optional serial/Audio) can now be
switched to the respective output ports. From these output ports, up to 16 consoles
(again, up to 10 km away) are controlled via remote units to be installed at each
console.
The changeover can be triggered remotely by a hotkey sequence (only in KVM
mode), using the serial interface (RS232) or by the built-in web interface.
A comfortable OSD (On Screen Display) allows the selection of the CPUs, user
administration and offers further administrative functions.

A special function called “Partner Viewing” allows copying one (or more) display
signal(s) to one or more additional displays. This mode is especially useful e.g. if
one display signal shall be shown on both the user display and a beamer or if the
monitor information shall be shared with an administrator. The “Follow Me”
function ensures that the monitor information is updated whenever the original
display signal source is changed.

ServSwitch™ DKM

16

 “Control Room” Mode: As a special case of the KVM Switch, you can choose

the “Control Room” Mode. In this mode, several displays are assigned to a work
place. A comfortable OSD (On Screen Display) allows at any time to choose from a
list of available CPUs the CPU to be displayed on a specific monitor.
With a hotkey sequence, you can switch keyboard and mouse to any of these
monitors for operation without need to know the associated CPU. Now you can
operate this CPU.
Also in this mode, one (or more) display signal(s) can be copied to one or more
additional displays (“Partner Viewing”).

 “Teacher/Student” System: Two configurations are available:

a) Attend up to 15 Students – Each student work place is connected by CATx­Duplex cable. Each CPU can be displayed at any work place – both student and
teacher work place – even simultaneously. The teacher can observe every student
work place.

b) Attend up to 31 Students – Each student work place is connected by CATx­Simplex cable. Each CPU can be displayed at a specific monitor, e.g. beamer or
large display – both student and teacher work place. The teacher can observe every
student work place.

A ServSwitch™ DKM system comprises a ServSwitch™ DKM and one or more
Local/Remote Units. The ServSwitch™ DKM and the Local/ Remote Units are attached by
CATx or Fibre interconnection cables.

The operation of a ServSwitch™ DKM requires always the use of Local Units and Remote
Units of a ServSwitch™-Extender.

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 wheel mice.

ServSwitch™- KVM standard devices with USB-HID connectors su pport
the extension of keyboard and mouse ONLY; use with other HID devices
(Human Interface Device) such as touch scr eens, graphics tablets, barcode

readers or similar may be successful – but there is no guarantee for this!
The ServSwitch™- KVM standard device is NOT suitable for use with
other USB- devices such as scanners, web- cams, data sticks etc.

ServSwitch™- KVM standard 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 by a USB hub but this does not raise the num ber of sup p orted
devices.

 Fibre-/CATx Devices: A ServSwitch™ Switch may be equipped with both CATx

GBICs and fibre GBICs. This allows to switch both fibre and CATx Signals with one
ServSwitch™ Switch.

Currently, it is NOT possible to connect devices of different
topologies (CATx and fibre). The related signals are switched
correctly but the data format is not compatible. If this
feature is required, please consider using our Cross­Repeater. Our technical support will assist you (cf. Appendix
E: Calling Technical Support

Page

139).

2.7 How to Use This Guide

This guide describes the installation and configuration of the ServSwitch™ DKM. Although
the connection and operation of the system is relatively straightforward, you should consider
the following before getting started:

2.7.1 Connection & Compatibility

The individual ServSwitch™ DKM components consist of:

 ServSwitch™ DKM includes the device and power supply.

 ServSwitch™- KVM/ Media Local Unit: includes the device, power supply and all

cables required to connect the ServSwitch™- KVM/ Media Local Unit to your CPU/
Signal source.

 ServSwitch™- KVM/ Media Remote Unit: includes the device and power supply

Please see also Package Contents (Page 28).

For information about connection and installation, see page 30.

2.7.2 DDC Information

Normally, it is not necessary to make any adjustments to the ServSwitch™- KVM/ Media
device. However, in some circumstances, it may be necessary to redefine the source of DDC
information for the CPU. By default, the ServSwitch™- KVM/ Media device uses its own
internal DDC table. If this setting does not satisfy your requirements, the DDC table can
either be switched to the DDC table of the locally attached screen or can be downloaded from
the remotely located screen and stored in the internal DDC table.

Default: Download from Remote Monitor
To modify the DDC Setup, see Loading the DDC information from the remote monitor (Page

159).

2.7.3 Selecting the moment of switching to the next frame

The transmission of screen data is not synchronous to the screen changes of the graphic card.
Normally, the transmission is terminated during the display of a frame on the screen (at the
remote unit). If the device switches to the new frame during the displaying period of the old
frame (somewhere on the screen), it is possible that you will see horizontal screen breaks at
the moment of switching (default). On the other hand, if the device idles until the actual
frame is displayed completely (until VSYNC) then the number of frames per second
transmitted may be reduced.

To modify the switching behaviour, see Setup at the Remote Unit (Page 161).

OVERVIEW

2.7.4 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. While the automatic color switching enhances the
number of frames, transmitted per second, fixed 24 Bit color depth gives smooth color grades
under all circumstances. Please select your preferred mode.

To modify the color depth, see Setup at the Local Unit (Page 159).
