The Digital Visual Interface is the next generation in display technology.
Over the years computers have got more and more powerful, and are taking up
less and less space. Until recently the same could not be said of display
technology. The traditional CRT (Cathode Ray Tube) style of monitor is
basically the same as is used in your TV. This ensured that computer monitors
often took up a quarter of your deskspace! Plus the system inherently suffers
from at least some level of distortion. With the latest flatscreen
technology, images are transferred digitally from a DVI enabled computer. The
picture is made up from thousands of discrete pixels ensuring picture
perfect, very high resolution image control.
The Digital Visual Interface (DVI) is the new standard for this form of
image transfer.
The AdderView DVI is the world's first electronic KVM switch to allow full
access to this exciting new technology.
FEATURES:
Digital quality for modern monitors
The arrival of modern digital flat-screen technology prompted a rethink of
video interfaces. The resulting DVI interface, which is fully supported by
the AdderView DVI, enables the video picture to be transferred from the
digital computer to the digital monitor without the inevitable loss of
quality caused by unnecessary analog conversions.
Reliable KVM switching without compromise
Exact pixel to pixel digital video transfer and maximum bandwidth support
ensures that you will never have to compromise on video quality.You can sit
back and enjoy high resolution razor sharp images on your flat screen display
whilst effortlessly switching quickly and reliably between your computers
using the mouse or keyboard. Fully electronic switching ensures that video
performance will not degrade with use and Display Data Channel support
enables optimal video driver configuration.
Innovative technology
The AdderView DVI is the first electronic KVM switch of its type that
enables high quality digital flat panel displays to be shared between several
computers. It achieves this using innovative digital circuitry that is
skillfully crafted to operate at the very high signalling speeds demanded by
DVI video. The stylish AdderView DVI provides the perfect accompaniment to
your quality flat-panel display.
SPECIFICATION:
AV2 DVI
Enables a keyboard, mouse and DVI monitor to control 2 computers.
AV4 DVI
Enables a keyboard, mouse and DVI monitor to control 4 computers
Features
Connectors
Most connectors are rear mounted to ensure a neat installation and are
colour coded according to the PC99 specification for easy identification.
Keyboard and mouse ports use 6 pin mini-DIN female connectors. Video ports
use standard 24-way DVI-D connectors. Options port is side mounted and uses
15-way standard D-type connector with proprietary pin allocation. DC power
connector provided for video-only and other special applications where
interface powering is not possible.
Controls
- Front panel key for computer selection.
- Numerical display shows selected computer and keyboard/mouse
activity.
- Optional remote controller connects to side.
- Base-mounted reset and option switches.
Computer Selection
Computers may be selected using the front panel key, keyboard hotkeys, a
three-button mouse or wheel mouse, RS232 data commands or the optional remote
controller. The hotkeys are selectable and are designed to be quick-fire
using a minimum number of key presses. The mouse may be used to select the
next or previous computer by holding down the centre button whilst pressing
the left or right button. Both keyboard hotkey and mouse switching may be
independently disabled if required. When cycling through channels using the
mouse or the hotkeys the user may configure the AdderView to select all ports
or just the ports that have powered PCs attached. RS232 switching is useful
for automated operation and the remote controller provides a convenient
control method without locating the AdderView on the desk.
Operation mode / cascadability
The keyboard, mouse and video are switched together so that the keyboard
and mouse are controlling the computer whose video is currently displayed on
the monitor. Non-selected ports emulate the action of the keyboard and mouse
so that the computer operates normally. The AdderView DVI may be used to
control more than 4 computers by connecting a computer port of one unit to
the control port of another unit in a tree-like cascade.
Mixed analogue / digital video and multi-head video operation
For applications that require mixed analogue / digital operation or multiple
video head switching, the AdderView DVI may be used to synchronously switch
other AdderView DVIs or AdderView GEMs. Refer to the manual for full details
Other Features
The AdderView provides a wide range of useful features including:
- User selectable password protection.
- Autoscan of all or active ports with selectable dwell times.
- Screen saver feature with selectable "kick in" time.
- User selectable keyboard hotkey combinations.
- Video may be disabled (channel zero selection).
- Ability to cycle between computers using hotkeys plus TAB.
Keyboard ports
Automatic mode emulation and NUM / CAPS / SCROLL updates ensures that the
keyboard is always in the expected state. Modes 1,2 and 3 are supported for
full compatibility. Keyboard data is kept in its native format to ensure
support for additional web control, hot media and other extra keys.
Mouse ports
The controlling PS/2 style mouse plugs directly into the AdderView. 2 and 3
button formats are supported. Most wheel and scroll mice are supported
including the Microsoft IntelliMouse and IntelliMouse Explorer. PS/2 or RS232
mouse connections to computers may be made in any combination. RS232 mice
require an additional cabling adaptor (VSA1). Prompt and stream mode support
ensures maximum compatibility. 3 button mice or wheel mice may optionally be
used to switch the AdderView's channel.
DVI video ports
Two or four single-link DVI ports operating up to 165MHz the full DVI
Specification, VESA DDC2B signalling supported. AdderView extends DVI video
cable runs by boosting the video signal.
Upgradeability
Flash upgradeable to support new devices by connecting a computer's serial
port to the options port and running a download program.
Software and hardware compatibility
Software independent operation ensures very wide compatibility that
includes Windows 3.X, WFWG, 95, 98, 2000, NT, ME, XP, DOS, Unix, Linux,
NetWare, OS/2 and BSD. Hardware compatible with desktop and laptop PCs,
RS6000, SGI and DEC Alphas.
Optional remote controller
Plugs into the options port at the side of the AdderView. Duplicates the
AdderView's front panel key and numerical display. May be attached to the top
of a keyboard or the side of a monitor by the Velcro strips provided. 60 x 29
x 12 mm. White / cream finish.
Power
For maximum convenience the AdderView draws its power from the attached
computers like a keyboard. Optional power socket provided for video only
applications. Interface ports individually fused with auto resettable fuses
to protect your computers.

Cables
AdderView to keyboard, mouse and monitors - 2m if interface powered or 5m
if PSU used. AdderView to computers - 5m if interface powered. When a PSU is
used the keyboard and mouse connections may be run at up to 10 metres to and
from the AdderView. It may also be possible to run DVI video at this
distance, particularly if the higher resolutions are not used, although this
cannot be guaranteed. Full range of high performance cables available.
