FEATURES

• Control multiple CPUs that output DVI

video with a keyboard, mouse, and one
or more monitors.

• Single-, dual-, and quad-head models

for either two or four CPUs.

• Supports 1600 x 1200 at up to 60 Hz.

• Dual-head and quad-head models

support compositing video for even
higher total resolutions.

• Can be cascaded to control more CPUs.

• Can be synchronized with compatible

switches to control more heads or both
DVI and analog CPUs.

If your CPUs output four independent video feeds, you can switch displays 

with resolutions up to 1600 x 1200 on four monitors as shown here. If your video card 

and monitor support composite pictures built from four video feeds, you can (with special

monitor cables) switch spectacular 3200 x 2400 displays on a single screen.

OVERVIEW

Do you have two or more computers that output Digital

Visual Interface (DVI) video? Would you like to monitor and
control them with one keyboard and mouse and one monitor
or set of monitors?

The ServSwitch Wizard

DVI could be the KVM switch you 

need. Based on our proven ServSwitch Wizard technology,
the ServSwitch Wizard DVI comes in six models that differ by
the number of CPUs they support (2-port or 4-port) and the
number of DVI video heads each attached CPU can have
(single-head, dual-head, or quad-head).

The ServSwitch Wizard DVI supports resolutions up to

1600 x 1200 pixels at refresh rates up to 60 Hz. (In fact, its
maximum pixel frequency of 165 MHz per port is the highest
single-link bandwidth supported by the DVI spec.)

If you’re using multi-head CPUs that output different

segments of the same image on each head to make a single
screen, the ServSwitch Wizard DVI can pass these through to
the monitor as normal: The ServSwitch Wizard DVI supports
composited resolutions as high as 2400 x 1600 (dual-head
models) or 3200 x 2400 (quad-head models).

If you have more than four CPUs to switch between, you

can cascade ServSwitch Wizard DVIs to handle as many as 256
of them. If your CPUs output more than four video feeds (that
is, they have more than four heads), you can “synchronize” a
pair of Quad-Head ServSwitch Wizard DVIs by running a
special serial cable between them. They will switch channels
simultaneously—for example, when you switch to CPU 3 on
one, the other will do the same. So, by running the “extra”

video feeds through the same CPU channel on the second
ServSwitch Wizard DVI, they can be handled transparently,
as if the two ServSwitch Wizard DVIs were one larger switch.

Synchronizing is also useful when you need to switch both

CPUs that output DVI and CPUs that output VGA-compatible
analog video. In this case, you can synchronize a ServSwitch
Wizard DVI with a regular ServSwitch Wizard or one of the
other switches in the ServSwitch Wizard family. The
ServSwitch Wizard DVI will handle the video from the DVI
computers and the keyboard and mouse signals from all of
the computers, and the other switch will handle the video
from the VGA-type computers. Because many DVI monitors
autosense and auto-adapt to either DVI or analog input, you
might be able to use a single monitor for the whole system.

The ServSwitch Wizard DVI can be used with IBM

that output DVI.

To connect your CPUs to the switch, we offer special

bonded cables that carry keyboard and mouse lines and one,
two, or four DVI lines (EHN450, EHN460, and EHN470). Keep
in mind that the maximum DVI distance on either side of the
Wizard DVI is 5 m (16.4 ft.) as per the DVI spec.

All of the multi-head ServSwitch Wizard DVI models come

with a power supply. The single-head models can usually get
enough power from the CPUs’ keyboard leads to operate; if
not, the PS649-R2 power supply is available separately.
