f you have several sources of
video that you’d like to display at
different places at different times,
here are a few things not to do:
1. Don’t settle for static,
expensive dedicated video feeds.
2. Don’t swap video cables by
hand.
3. Don’t subject your video
devices to ugly and potentially
damaging mechanical video
switching.
4. Don’t pay for extra
switching (keyboard, mouse, etc.)
that you don’t need.
What should you do? Consider
a ServSwitch™ Brand Matrix
Video Switch. You can use it to
electronically switch the video
signals coming from as many as
four source devices among as
many as four destination devices.
In the standard application,
computer CPUs will be the
sources and computer monitors
will be the destinations. But with
the proper cabling and signal
conversion (and as long as the
destination devices can handle it),
almost any video device can be
involved—TVs, VCRs, cameras,
I
projectors, DVD players, etc.
This is because the Switch
can handle almost any kind of
video synchronization: RGBHV (as
used in VGA, SVGA, and other
types of computer video), RGBS
(as used in NTSC and PAL TV
signals), and RGsB (“sync on
green”). It has a vast amount of
bandwidth—enough to carry
video at resolutions up to 1600 x
1280 at refresh rates up to 85 Hz.
All of its inputs and outputs are
buffered, so you always get the
sharpest possible images. To top
it off, it can drive those signals as
far as 150 ft. (45 m)!
The ServSwitch™ Brand
Matrix Video Switch can be
controlled in either of two ways.
For one, it comes with a standard
serial numeric keypad, powered
by the Switch, that plugs into the
Switch’s rear panel. Press the
keypad buttons in the sequence
output–decimal point–input–Enter
key to make a switch. For
example, press [3][.][1][Enter] to
switch the input from CPU #1 to
output to monitor #3. If you press
zero for the input number, the
output channel will be blanked
(the Switch won’t send it any
video signal). If you press the
asterisk key for the output
number, the input channel will be
broadcast to all outputs.
The Switch’s LEDs will always
show you which output channel is
receiving which input. Anyone
who can interpret these LEDs and
press a few buttons can use the
Switch!
The keypad’s cable is 6 ft.
(1.8 m) long, but you can use DB9
extension cable (not included) to
extend your “roaming radius” out
to RS-232’s maximum distance of
50 ft. (15.2 m).
The other way to control the
Switch is by attaching a PC or
other serial device that can send
the Switch the ASCII characters
or hex codes equivalent to the
keypad keypresses. In this way,
switching can be automatically
controlled for displays, demos,
and so on.
The Switch has a universal
power supply; with the proper
input cord, you can plug it in just
about anywhere in the world.
Direct any of your video
output to different
locations for display,
recording, broadcasting—
you name it!

You might also need:
CAUTION: If you use adapters or converters to attach non-VGA equipment, all destination devices must be capable
of handling the video signals from all source devices. For example, driving high-end workstation video to a monitor
whose maximum refresh rate is too low could result in oversyncing and damaging the monitor.

Why Buy From Black Box? Exceptional Value. Exceptional Tech Support. Period.
Recognize any of these
situations?
• You wait more than
30 minutes to get through to
a vendor’s tech support.
• The so-called “tech” can’t
help you or gives you the
wrong answer.
• You don’t have a purchase
order number and the tech
refuses to help you.
• It’s 9 p. m. and you need help,
but your vendor’s tech
support line is closed.
According to a survey by Data
Communications™ magazine,
90% of network managers
surveyed say that getting the
technical support they need is
extremely important when
choosing a vendor. But even
though network managers pay
anywhere from 10 to 20% of their
overall purchase price for a basic
service and support contract, the
technical support and service
they receive falls far short of their
expectations—and certainly isn’t
worth what they paid.
At Black Box, we guarantee
the best value and the best
support. You can even consult our
Technical Support Experts before
you buy if you need help selecting
just the right component for your
application.
Don’t waste time and
money—call Black Box today.
