DVI-D CATX SWITCH/SPLITTER

Welcome to the CATX DVI-D Family!

Thank you for purchasing a CATX DVI-D Switch! We appreciate your business, and we think you’ll appreciate the many ways that your CATX DVI-D system will save you money, time, and effort.

The CATX DVI-D 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 Singlehead ports (a “Singlehead” extender system supports 1x monitor, 1x keyboard, 1x mouse) or up to 3 Dualhead ports (a Dualhead 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 CATX DVI-D 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 CATX DVI-D- Extender technology for the transmission of DVI- Monitor and USBKeyboard and Mouse signals over CATx- cable.

The operation of a CATX DVI-D Switch always requires at least one Local Unit and up to seven Remote Units from the CATX DVI-D-Extenders range.

DVI-D CATX SWITCH/SPLITTER

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 CATX DVI-D 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 CATX DVI-D Switch, including how to install, operate and troubleshoot it. For an introduction to the Converter, see Chapter 2.

DVI-D CATX SWITCH/SPLITTER

2. Overview

2.1 Introduction

The CATX DVI-D 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 Singlehead switches (a “Singlehead” extender

system supports 1x monitor, 1x keyboard, 1x mouse) or up to 3 Dualhead switches (a Dualhead 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 comprises a CATX DVI-D Switch and one or more Local/Remote Units. Optionally, several CATX DVI-D Switches can be cascaded in maximally two stages (master/slave). The CATX DVI-D Switch and the Local/ Remote Units are attached by CATx interconnection cables.

The operation of a CATX DVI-D Switch always requires (at least) one Local Unit of a CATX DVI-D-Extender and up to seven Remote Units of CATX DVI-D-Extenders.

2.7 How to Use This Guide

This guide describes the installation and configuration of the CATX DVI-D Switch. Although the connection and operation of the system is relatively straightforward, you should consider the following before getting started:

Connection & Compatibility

The individual CATX DVI-D Switch components consist of:

• CATX DVI-D Switch for CATx: includes the device and power supply.

• CATX DVI-D- KVM Local Unit: includes the device, power supply and all the cable

required to connect the CATX DVI-D- KVM/ Media Local Unit to your CPU/ Signal source.

• CATX DVI-D- KVM Remote Unit: includes the device and power supply

Please see also Package Contents (Page 19). For information about connection and installation, see page 21.

DDC Information

Normally it is not necessary to make any adjustments to the CATX DVI-D- KVM/ Media device. However, in some circumstances, it may be necessary to redefine the source of DDC information for the CPU. By default, the CATX DVI-D- KVM/ Media 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 can be downloaded from the remotely located screen and stored in the internal DDC table.

To modify the DDC-Setup, see Setup at the Local Unit (Page 45).

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 reduces.

To modify the switching behaviour, see Setup at the Remote Unit (Page 48).

INSTALLATION

3. Installation

SERVICE SETUP

6. Service Setup

6.1 CATX DVI-D-Switch for CATx

Normally, it is only necessary to make adjustments during installation. In order to make these adjustments, you do not have to open the CATX DVI-D Switch. All

settings can be made from the outside using the Operating Mode Selector (DIP switch).

By selecting a new operating mode, the allocation of inputs and outputs may be changed. In doing so, it is possible to interconnect two transmitters: this may damage the

connected equipment.

The location of the operating mode selector (DIP switch) is shown below:

For the selection of a new operating mode:

1. Switch off the CATX DVI-D-Switch.

2. Select a new operating mode according to following table.

By selecting a new operating mode, the allocation of inputs and outputs may be changed. In doing so, it is possible to interconnect two transmitters: this may damage the

If you have loaded several DDC configurations without achieving a satisfactory result, you can restore the original (default) DDC table. To do this:

• Switch off the Local Unit.

• Open the Local Unit as described above.

• Remove the jumper on JP1 (jumpers JP1 and JP2 are open now – on dualhead devices

remove the JP1 jumper on BOTH PCB’s!).

• Switch on the Local Unit.

• After a successful reprogramming of the DDC-EPROM, the ‘Video-OK’ LED at the

Local Unit blinks rapidly for approx. 1 second.

• Switch off the Local Unit.

• Replug jumper JP1 (dualhead devices: replace the JP1 jumper on BOTH PCB’s!).

• Close the Local Unit.

• Switch on the Local Unit.

SERVICE SETUP

Loading the DDC information from the remote monitor

To load the DDC information from the remote monitor:

• Switch off the Local Unit and the Remote Unit, unplug the video-cable to the remote monitor (dualhead devices: unplug BOTH Monitors!).

• Open the Local Unit as described above.

• Move the jumper on JP3 to position JP2 (Please bear in mind the position of JP3. Note:

both – JP1 and JP2 are plugged now). On dualhead devices move the jumper from JP3 to JP2 on BOTH PCB’s!

• Switch on the Local and Remote Unit (Please ensure, the CATx- interconnect cable is connected – On Dualhead devices, connect BOTH interconnect cables!)

• Wait until the LINK-LED is illuminated (see above).

• Plug the remote monitor’s video-cable into the Remote Unit. Switch on the monitor if it

is switched off. On dualhead devices, connect and switch on BOTH monitors!)

• The DDC information of the remote monitors is read automatically, transferred to the Local Unit and stored into the DDC-EPROM.

• After a successful reprogramming of the DDC-EPROM, the Video-OK’ LED at the Local Unit blinks rapidly for approx. 1 second.

• Switch off the Local Unit and the Remote Unit.

• Unplug jumper JP2 and plug it back to position JP3. On dualhead devices move the

jumper from JP2 to JP3 on BOTH PCB’s!

• Close the Local Unit as described above.

• Switch on the Local Unit and Remote Unit.

Selection of Colour depth

By default, CATX DVI-D Switch Media/KVM Extender units transmit video with 18-bit colours (=256K colours). You can also set up the units to transmit 24-bit (=16M colours). Low colour depth enhances the number of frames transmitted per second, high colour depth gives smooth colour grades.

The main PCB then will look like this:

Use the diagram to locate jumpers.

Selecting the moment of switching to the next frame

The transmission of screen data is not synchronous to the screen change of the graphic card. Normally, the transmission is terminated when a frame is displayed on the screen. If the device switches to the new frame during HSYNC, the displaying period of the old frame, you may see horizontal screen breaks at the moment of switching (default). Alternatively, you can set up the units to idle until the actual frame is displayed completely, during VSYNC. Using this method, the number of frames per second transmitted is lower.

Moment to switch

JP3 Behaviour

Switching during HSYNC (default)

Higher frame rate but (possibly) horizontal breaks detectable

Switching during VSYNC

Lower frame rate, no horizontal breaks detectable but (possibly) stepping pictures

OPERATING MODES

7. Operating Modes

7.1 Multiplex- Repeater

The DVI signals (and optional audio) originating from a signal source are distributed and extended – depending on the configuration – on up to 7 equivalent outputs. The signals of the CPU (signal source) are transmitted to a Local Unit which is attached to the CATX DVI-D Switch by interconnection cables (CATx). The transmission between the CATX DVI-D Switch and up to 7 Remote Units is also done by interconnection cables (CATx). Optionally, instead of Remote Units, further CATX DVI-D Switches can be installed for a second stage of distributors. Further Remote Units can be connected to the second stage repeaters, allowing up to 49 display units to be headed.

The distance between a Local Unit and CATX DVI-D Switch or between a CATX DVI-D Switch and Remote Unit or between two CATX DVI-D Switches may amount to in each case up to 140m allowing installations in distributed applications.

Configuration ‘Multiplex-Repeater’ – 1 Source up to 7 Displays

A single signal from a Local Unit is distributed on up to 7 outputs and transferred over CATx- cables on up to 7 Remote Units. Using a second stage of Multiplex Repeaters up to 49 monitors can be supplied with video (and optionally audio).

Configuration ‘Multiplex-Repeater’ – 2 Sources, each up to 3 displays

Two different signals from two Local Units are each distributed to 3 outputs and transferred over CATx- cables to 3 Remote Units. Using a second stage of Multiplex Repeaters up to 2x9 (2x21) monitors can be supplied with video (and optionally audio).

Configuration ‘Multiplex-Repeater’ – 4 Sources on 4 Displays

Four different signals from four Local Units are transferred over CATx- cables to one equivalent Remote Unit. This allows an extension to the cable length, if the usual 140m distance by CATx- cables is not sufficient.

Serial Interface

(RS232)

OPERATING MODES

7.2 Crosspoint- Switch

In “Crosspoint- Switch“ operating mode, each port of the CATX DVI-D Switch can be used either as an input (to a Local Unit) or as an output (to a Remote Unit). Thus any combinations between 1x input/7x output and 7x input/1x output are possible. The device offers no channel monitoring in this mode so you must ensure the correct connection of the CATx- cables. Incorrect cabling may switch two inputs or two outputs to each other and this could damage your equipment!

An incoming DVI (+audio) signal can be switched and extended to one or more outputs allowing you to output the signal to several displays at the same time (broadcast functi on). The signal from the CPU (signal source) is transmitted over a Local Unit and CATx- cables to the CATX DVI-D Switch. From the CATX DVI-D Switch, the transmission continues over CATx- cables to up to 7 Remote Units. Alternatively, a further CATX DVI-D Switch (slave) can be used between the first stage switch and further Remote Units. Therefore complex switching modes can be achieved.

During operation, the allocation of ports as input or output is fixed. Devices must be attached according to the following diagrams.

The control of the switching status is made by the integrated, serial interface. Switching commands can be converted directly here. Switching combinations can be additionally stored as macros. These can be called up with a short command or by using the push-button on the device. Using the serial interface, macros can be selected directly; with the push-button, the macros are successively activated.

7.3 Singlehead KVM- Switch

Using one console (monitor, keyboard and mouse) up to 7 CPUs can be controlled remotely. The distances between the CPU and CATX DVI-D Switch and between CATX DVI-D Switch and console may amount in each case to up to 140m.

The switching between the CPUs can be carried out at the attached keyboard, push-button at the device or over the serial interface.

Cascading of the CATX DVI-D KVM- Switch in two stages is in all application areas allowed so up to 49 CPUs to be addressed.

In addition to the DVI- signals and USB for keyboard/mouse, bi-directional stereo-audio + serial (RS232/V24), can be transferred by the choice of appropriate Local/ Remote Units.

TROUBLESHOOTING

8. Troubleshooting

Monitor

There isn’t a picture.

Check the power supply connection at the Local and Remote Unit. Is the Power LED at the Local and Remote Unit illuminated? If not, the internal power supply may be damaged or there may be an internal error.

Check that the interconnection cable is connected at the Local Unit and the Remote Unit. Is the Link Status LED illuminated? If not, there may be a problem with the interconnection cable:

Are there errors through data transmission over CATx- cable (cable too long, too

high attenuation or too much EMI interferences)? Is the Data Error LED illuminated or blinking? 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 connecting a monitor to the local output to see whether or not there is a signal.

“Juddering” pictures at video presentations

With high monitor resolutions, the data volume that can be transferred may exceed the available bandwidth, so the data throughput must be reduced. For this, the device uses a RLE compression algorithm. If the necessary com pres sion factor is not reached, not all pictures of the graphic card are transferred (frame dropping) and the video pr esentation may begin to “ju dder”.

Hint: Use a lower resolution, which is a little larger than the resolution of the stored film material. If the monitor has a higher resolution, then the monitor can take over the scaling of the video data. For the image quality it is irrelevant whether the scaling is done via the CPU or via the monitor.

Hint: Set the colour depth to 18 bits. Usually the human eye is not able to differentiate between so many different colours with moving pictures. A reduction on 18 bits makes the data volume that has to be transferred smaller without loss of image quality.

DVI-D CATX SWITCH/SPLITTER

Keyboard

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

Wrong cable is plugged in. 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? The other console is active. Gain control by any keyboard action or by pressing left

and right mouse buttons simultaneously.

USB- Keyboard/ Mouse

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 check Appendix F: List of supported USB devices, on page 106.

Your USB- Mouse makes ”jerky leaps”

Hint: Use a lower resolution or a background which can be compressed better: Please avoid photo-backgrounds or colour gradient – single-coloured backgrounds are optimal and permit highest possible compression rates and highest frame rates.

Your USB- Mouse moves like its on “elastic”

This problem is caused by several factors which lead to a time delay between mouse movement and display on the screen. Contributions to the total delay consist of (numerical data are approx. values):

• Mouse movement/ transmission of data to the CPU (5 – 15 ms)

• Processing time in the CPU until mouse movement at the graphic output

appears (50 – 70 ms)

• Transmission of the graphic data into the extender-system and transmission to the Remote Unit (15 – 45 ms)

TROUBLESHOOTING

• Processing time in the graphical output device (15 – 100 ms, where 15 ms are only reached with CRT tubes)

The majority of the delay, between 85 and 230 ms, is not a consequence of the extender-system. The extender system is responsible for 5 -15 ms mouse movement/ transmission to the CPU plus 15 – 45 ms acquiring the graphic data and transmitting it to the Remote Unit. Our measurements show that time delays greater than about 100-150 ms become noticeable and bothering. Therefore, if an extendersystem increases the mouse signal delay from, say, 100ms to 140ms you may begin to experience the “elastic” delay problem.

If you use a slow response TFT screen you may already have a total response time of up to 175 ms, right at the threshold level. The addition of an extender line to such a system will appear to cause the “elastic” mouse delay problem even though the extender system is responsible for only a small part of the total problem.

Hint: Use a display with a shorter response time (please note: the response time indicated by the manufacturer is a measure of how quickly two successive pictures can be displayed, not how long it takes for a signal from the input interface to reach the screen). Use a lower resolution or a background which can be compressed better: Please avoid photo-backgrounds or colour gradients – single-coloured backgrounds are optimal and permit highest possible compression rates. If the transmission needs to drop frames (because the RLE compression algorithm does not reach the required data reduction) you need to add approx. 17 ms @ 30fps and approx. 34 ms @ 20fps

USB-HID-devices

Your USB-HID device does not work

Although our interface supports HID devices, we can’t ensure that every connected device will operate successfully. If you have any compatibility problems, please contact our technical support.

Other USB-devices

Your USB- device does not work

You have connected a non-HID device. The extender system supports HID devices

only. All other devices are incompatible with the CATX DVI-D Switch system.
