Recommendations for the twisted pair cable

The transmission of all signals of the DVIVision system is carried out through one
twisted pair cable (category 5e or better).

The connection of several segments using patch panels and connection ports is
permitted. However, connections through active network components 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 achieved depends on the quality of the used 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.

To ensure reliable operation even in environments with interference, installation
cables with at least AWG24 coding have to be used for lengths over 80 metres.

Wire gauge Cable type Category Recommendation

AWG22 Installation 5e, 6 or 7 up to 140 m

AWG23 Installation 5e, 6 or 7 up to 130 m

AWG24 Installation 5e, 6 or 7 up to 120 m

AWG26/27 Patch cable 5e, 6 or 7 up to 80 m

The lengths that are mentioned in the table above must be interpreted as the sum

USB and PS/2 signals of the variants -ARU and -U

If you use a variant of DVIVision that supports USB devices, it is necessarily required
to connect the USB CPU interface of the computer module (DVIVision-CPU) with the
USB interface of the computer. The data of the USB devices are transmitted to the
computer through this interface.

The signals of keyboard and mouse are also transmitted through this USB connection.
If you prefer to transmit the signals of keyboard and mouse through the PS/2 inter-

faces, connect the interfaces Mouse CPU and Keyb. CPU with the PS/2 interfaces of
the computer.

Supporting any resolution

In principle, the DVIVision system 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 x 480 pixels at 60 Hz and 1600 x 1200
pixels at 60
VESA SMT. 1920

Almost any refresh rate and resolution within the technical constraints are possible.
The available display modes are largely dependent on the graphics card, the gra
phics 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.

Hz are possible for the common timing standards by VESA DMT and

x 1200 pixels at 60 Hz is transmitted according to VESA CVT-RB.

-

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.

the remote monitor already during the boot process. Even if the computer module
or the user module are turned off or if the devices are not interconnected, the proper
ties of the most recently connected monitor or a default data block are provided in
the DVIVision system.

The DDC information of the monitor are basically transmitted one-to-one. In case,

The expansion DVI-Power

The expansion DVI-Power

The expansion DVI-Power is provided for the variants DVIVision-AR and -ARU to
control the buttons

Scope of delivery

The scope of delivery of DVI-Power expansion includes the following items:

 G&D Power Card (slot card for installing in the computer)
 connection cable to connect G&D Power Card and computer module
 single-sided ready-made cable for connecting a panel to the user module
 2 x two-pole connection cable (0,4 metres)
 2 x two-pole extension cable (0,4 metres)

Functionality

The remote control of both the ATX-Power and the Reset function is carried out
through a panel with two buttons. The panel is installed at the remote console.

The panel for the operation of DVI-Power is not included in the scope of delivery
of DVI-Power and has to be build by an expert.

The panel is connected to the system through a four-pole modular socket on the
back panel of the user module (DVIVision-CON). The connection cable that is pro
vided in the scope of delivery has to be fixed to the panel (see Allocating the connection

cable for the panel on page 43).

Installation guidelines

Installing the G&D Power Card into the computer

At first, install the G&D Power Card into the computer:

1. Take the manual of the computer and of the motherboard that is installed within

the computer.

2. Open the casing of the computer to gain access to the expansion slots.

3. Assemble the G&D Power Card of the expansion DVI-Power to a free expansion

slot of the computer.

The G&D Power Card requires no slot at the motherboard of the computer. The
installation only serves as assembly position for the ATX module at the back
panel of the computer.

Connecting the signal lines to the slot card

In the following, the signal lines ATX-Power and Reset of
the motherboard are connected to the pin bar of the
G&D Power Card (see figure). A further connection at
the computer casing guarantees the use of these buttons.

Write down the plug positions of the cables, which are
leading from the ATX-Power button and the Reset but
ton of the casing to the motherboard. Afterwards, dis­connect the cables.

-

Pwr-Sw: Connect the ATX-Power button cable of the
computer casing to these pins. In case the connection cable is not long enough, it
can be extended with one of the extension cables.

Pwr-MB: Connect the pins you have written down before with the plug position of the
ATX-Power button on the motherboard. Use one of the supplied connection cables for
this purpose.

Res-Sw: Connect the Reset button cable of the computer casing to these pins. In case the
connection cable is not long enough, it can be extended with one of the extension cables.

Res-MB: Connect the pins you have written down before with the plug position of

Reset button on the motherboard. Use one of the the supplied connection cables

the
for this purpose.

Control Panel: Connect the panel cable to this interface at the user module.

Operating the expansion DVI-Power

The functions of the panel buttons correspond to the functions of both the ATX-Power
button and the Reset button at the computer casing.

Depending on the BIOS setting of the computer, in some cases the panel’s ATX-
Power button has to be pressed for five seconds to turn off the computer.

If necessary, check and change the respective setting within the BIOS of the com­puter to deactivate the delay.

Motherboard: The motherboard is the mainboard of a computer on which

further components are installed (for example processor and
main storage).

Multi-channel: The multi-channel variants of the DVIVision support several

video signals for each computer. Up to three video signals of
each computer can be connected to the variant MC3, for
example.

NUM: In addition to the numerical keys of the main key block, the

numerical key block of a keyboard is also provided with
numerical keys.

To differentiate between these numerical keys, the identifier
NUM is prefixed to the keys of the numerical key block
(e.g. NUM 1).

Numeric key: The ten numeric keys of the standard keyboard are located in

the upper row of the main key block. These keys are labelled
with 1 to 0.

Panel: The required panel to operate the extension DVI-Power usu-

ally is an input device with two separate keys. The panel is
not included in the scope of the delivery of the extension.

PS/2 interface: The PS/2 interface is a common interface for the connection

of input devices such as keyboard and mouse. To distinguish
the connection of keyboard and mouse, different colour
codes (purple: keyboard; green: mouse) are used.

Reset: A reset causes the computer to reboot. Most computer cas-

ings contain a special reset button.

Scancode set: If a key on the keyboard is pressed, the keyboard processor

sends a data packet called scancode.
There are two common scancode sets (sets 2 and 3), which

contain different scancodes. The majority of the recent key
boards use the scancode set 2. The DVIVision system inter­prets all inputs of a PS/2 keyboard by default with the
scancode set 2.

Setup key: By pressing a setup key, a function can be released after the

activation of the setup mode

Setup mode: After the setup mode of the DVIVision system has been acti-

vated, you can change the preset key combinations, reset the
default settings or change the scancode set of the PS/2 key
board.

Shift key: The Shift key of a keyboard is pressed to key in a capital let-

ter instead of the respective small letter.

User module: The transmitted signals of the computer module are received

at the user module and displayed at the console.
