FEATURES
• Extend DVI-I video in real time to
high-definition monitors, video
projectors, and other output devices
with DVI interfaces.
• By using fiber, you receive highly secure,
EMI/RFI-resistant extensions at much
longer distances—as far as 400 meters!
• Ideal for digital signage links to
multipanel video walls.
Send digital/analog signals from three PCs over fiber
to three remote video signs and displays.
OVERVIEW
Set up multiple high-resolution DVI displays at extended
distances for digital signage and video distribution applications.
The 3-Channel DVI Extender enables you to locate up to three
digital DVI output devices as far as 400 meters (1312.3 ft.)
away—without resolution loss.
The extender kit uses 12-fiber multimode fiber optic
cabling to send signals between transmitter and receiver
units. By distributing and extending video over fiber, you’re
guaranteed secure, error-free video in even the noisiest of
environments. Electromagnetic interference doesn’t disrupt
the video signal, and neither do power anomalies caused by
lightning and power surges. You get overvoltage protection
for your transmission routes.
This makes the 3-Channel DVI Extender an excellent choice
for mission-critical video-distribution applications, including
those in heavy-duty industrial plants, and military and
government installations. It‘s also a great choice for TV
studios, training and education environments, and retail kiosk
and PoS applications where you want to extend quality video
at great distances. The 3-Channel DVI Extender transmits
video signals without compression, ensuring completely
loss-free data extensions, and full video refresh rates. This
gives you a high-quality image even at higher resolutions.
Use the extender kit with high-definition monitors and
panels, or any display device with a DVI interface. The input
side handles both digital and analog video signals from PCs
or video source equipment; the receiving side’s output ports
are digital. Each channel supports data rates up to 3.6 Gbps
with a maximum resolution of WXGA (1920 x 1200 at 60 Hz).
If you use 50- or 62.5-µm multimode cabling, the extender
can cover distances up to 400 meters (1312.3 ft.).
You can also attach video output devices on the local side,
linking one or more monitors to the sender unit, for instance.
The kit includes a serial RS-232 cable, which you can use to
attach a console for configuring the extender and updating
its firmware. You also get an installation CD with a device
configuration program. Following desktop menus in the
program, you can easily set DVI and VGA video settings and
fine-tune the analog input signal for contrast and brightness,
horizontal and vertical screen positions, and screen width.
You can also adjust analog phasing for the pixel scanning
time to optimize the image quality.

Upgrading from VGA to DVI video.
Many new PCs no longer have traditional Cathode Ray
Tube (CRT) computer monitors with a VGA interface. The
latest high-end computers have Digital Flat Panels (DFPs) with
a Digital Visual Interface (DVI). Although most computers still
have traditional monitors, the newer DFPs are coming on
strong because flat-panel displays are not only slimmer and
more attractive on the desktop, but they’re also capable of
providing a much sharper, clearer image than a traditional
CRT monitor.
The VGA interface was developed to support traditional
CRT monitors. The DVI interface, on the other hand, is
designed specifically for digital displays and supports the
high resolution, the sharper image detail, and the brighter
and truer colors achieved with DFPs.
Most flat-panel displays can be connected to a VGA
interface, even though using this interface results in inferior
video quality. VGA simply can’t support the image quality
offered by a high-end digital monitor. Sadly, because a VGA
connection is possible, many computer users connect their
DFPs to VGA and never experience the stunning clarity their
flat-panel monitors can provide.
It’s important to remember that for your new DFP display
to work at its best, it must be connected to a DVI video
interface. You should upgrade the video card in your PC when
you buy your new video monitor. Your KVM switches should
also support DVI if you plan to use them with DFPs.
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.
