Operation
Operation
The computer, which is connected to the computer module (DVIVision-CPU), can be
operated at the remote console of the user module as well as at the local console of
the computer module.
After both consoles have been initiated, they are enabled to operate the computer.
NOTE: In the default setting, the monitors of both the remote and the local console
of the DVIVision system always display the same image at the same time – independently from the input lock.
The paragraph Changing the video mode of user consoles on page 27 explains how this
setting can be changed.
Concurrent operation of the DVIVision system
If a user carries out a keyboard or a mouse input, the DVIVision system automatically locks the input devices of the concurrent console. The lock is lifted if no inputs
are made at the active console during the adjusted timing of the automatic input
lock (default: 1 second).
After the automatic input lock has been lifted, both consoles are again able to operate
the computer.
As an alternative to operate the computer concurrently through the consoles, the
exclusive operation (see below) can also be activated.
Related topics:
 Changing the timeout of the automatic input lock on page 25
 Changing the video mode of user consoles on page 27
Exclusive operation of the DVIVision system

console access can be activated in the setup menu.
If this function is switched on, the user of the DVIVision system can activate the
exclusive operation by pressing the key combination Hotkey+PrtScr (default: Ctrl+PrtScr).
After having pressed this key combination, the input devices of the concurrent console are deactivated. By pressing the key combination again at the console where the
permanent input lock has been activated, users at both consoles are again able to
operate the DVIVision system.
After the permanent input lock has been activated at one console, the Scroll LEDs

Optimising the video image
The video signal is usually transmitted between the computer module and the user
module in a compressed way. Thanks to this compression, the image on the console
monitors are normally displayed without losses and judders.
The video data to be transmitted and the preset video settings can cause the following effects.
Tearing: The monitor image consists of two subsequent frames that are partly dis-
played. The lower part of the image shows a part of the old frame, the upper part
shows a part of the new frame. At the point where both frames touch, the image
appears to be “torn”.
NOTE: The HDIP mode (High Dynamic Image Processing) prevents the tearing effect
and provides the best image quality even for moving images.
Studdering: The number of transmittable pixels is limited by the transmission band-
width. If you have selected a high resolution and the image contents change fast,
some image may be skipped. The video image may seem jerky.
By reducing the colour depth to 18 bits, you can maximise the number of pixels to
be transmitted. Depending on the image contents, this may cause slight colour gradiations.
Latencies: The additional processing of the video signal cuase a short latency in the
HDIP mode. This latency may be noticed during fast mouse movements. Deactivate the HDIP mode to avoid such latencies.
Use the setup menu to optimise the video image for each video channel. Optionally,
you can use the setup keys to switch between the following profiles that apply to all
video channels:

Using the noise filter
By default, the computer module analyses and compresses the computer’s incoming
video signal and transmits it to the user module. Due to this compression, the data
volume to be transmitted can be considerably reduced.
In order to apply the compression, the image segments in the frames must not be
changed.
The device drivers of some graphics cards produce image noises in the video signal:
The colour values of frames the user perceives as evenly coloured differ slightly.
NOTE: The frames’ colour values also change for “fixed images”. As a result, the
compression cannot be applied and all frames of the video signal are transmitted.
Due to the missing compression, a high-resolution video signal of a computer with
such a device driver leads to a large data volume that is transmitted between computer
module and user module. This might affect the performance of the DVIVision system.
Activate the low or high noise filter level if you experience performance losses. This
way, the colour values are adjusted and the compression is possible.
NOTE: With Multichannel variants, the selected noise filter level applies for all video
channels.

NOTE: This factor is caused by weak or disturbed DVI signals of the connected

Recommendations for twisted pair cables
The transmission of all signals of the DVIVision system is carried out through one
twisted pair cable (category 5e or better).
NOTE: It is permitted to connect several segments of a cable connection with patch
panels and connection ports. It is, however, not permitted to connect active componentss such as network switches, hubs or repeaters are not permitted.
The data transmission is reliable over a distance of at least 100 metres using a regular standard twisted pair cable (category 5e or better). The distance that can actually
be bridged depends on the quality of the applied cable. High-quality S-STP cables
with an AWG22 wire gauge coding can bridge a distance of up to 140 metres. Patch
cables with an AWG26 wire gauge coding can only bridge a maximum of 80
metres.
In order to ensure a reliable operation even in environments with interferences,
installation cables with at least AWG24 coding have to be used for lengths over 80
metres.

Temperature warnings
The temperature in the user module as well as in the computer module of the
DVIVision-MC4 variant is permanently moitored.
IMPORTANT: To protect the device from overheating, the video signal of the channels 2 to 4 is switched off as soon as the temperature reaches the critical value!
Before the temperature reaches the critical value, the user is warned through several
alarm signals:
Alarm level
Action
≥ 70 °C
Blinking Sys-LED at device.
≥ 71 °C
All four monitors of the user module display the image with a blinking frame.
≥ 72 °C
All four monitors of the user module display the image with a fast blinking
frame.
≥ 73 °C
Video channels 2 to 4 are switched off; the monitors 2 to 4 display no image.
The monitor of video channel 1 still displays the image with a fast blinking
frame.
Support of any resolution
IMPORTANT: Display modes that support interlace are not supported by the
DVIVision system!
The DVIVision system generally supports all resolutions that can be transmitted
through a single link interface according to the DVI specification 1.0.
This restriction mainly affects the pixel rate, which can reach from 25 MHz to
165 MHz. Therefore, resolutions between 640 × 480 pixels at 60 Hz and 1600 × 1200
pixels at 60 Hz are possible for the common timing standards by VESA DMT and
VESA SMT. 1920 × 1200 pixels at 60 Hz is transmitted according to VESA CVT-RB.
Almost any refresh rate and resolution within the technical constraints are possible.
The available display modes are largely dependent on the graphics card, the graphics driver, the operating system and the connected monitor.
The video data that are transmitted from the computer to the computer module
(DVIVision-CPU) are transferred to the monitor of the remote console with the same
timing. The signal’s frequency and display position at the computer module therefore correspond to those of the graphics output.
G&D DVIVision · 45
Further information
NOTE: While generating the video signal, some graphics cards differentiate
between digital and analog output. Such graphics cards generate digitally output
image signals with partly non-standardised timings. Such timings do not comply
with the monitor’s default to reduce the frequencies of the digital signals.
Normally, this does not affect the DVIVision system and the digitally connected
displays. Due to the non-standardised timing, analog monitors might not be able
to display the image size and the image position properly.
