Product Overview
TheKD-VTCA3
ClearColor3 is the world’s smallest adapter on the market to “glue” your VGA
(RGBHV) devices to Component Video (YPrPb) HDTV monitors. ClearColor3 is
the ideal choice to drive your Component Video displays from VGA sources like
your HDTV Set Top Box or personal computer (PC). ClearColor3 works with
HDTV RCA®Set Top Boxes, HD monitors like Panasonic®and Sony®, and all
video formats — 480p, 720p, 1080i/540p, NTSC, PAL, interlaced or
progressive. With ClearColor3, there is also SCART compatibility, and a VGA
loop-through permits you to simultaneously drive a VGA and Component Video

monitor. With your cost-effective KDS ClearColor3 product, you get
crystal-clear processing and you can drive monitors with cable lengths up to
50 feet.
Why do you need a Video Adapter?
The video industry has produced many different products to process, switch,
and distribute your video. In many instances, the video input or output
formats of these products are not compatible. For example, you may have an
application where you would like your VGA-out (RGBHV) HDTV Set Top Box or
personal computer to drive your Component Video (YPrPb) display.

What do you do? One less-palatable option is to purchase all new equipment
that is totally compatible, which is a significant investment and limits you for
the future to ever consider equipment that does not conform to the standard
you purchased. At Key Digital Systems, we have a better solution for you. We
have designed economical, high-quality video adapters, which “glue” your
components that may have been designed to diverging standards:

*NOTE: When using your ClearColor3 with a VGA personal computer input,
special care should be given to set your PC to the appropriate resolution
that will be recognized by an HDTV Component Video monitor. A freeware
program called PowerStrip helps to do this, and is available from
http://www.entechtaiwan.com/ps.htm.Various experts have published guides
on how to use PowerStrip in the application of HDTV. One of these guides is
included at the end of this manual.

QUICK SET-UP
Connecting and using yourKD-VTCA3
ClearColor3 is a simple process.
NOTE: Do not attempt to connect power to the unit until you have completed
all Steps 1 – 4.
STEP 1: Determine your configuration requirements. The primary function of
theKD-VTCA3
QUICK SET-UP

ClearColor3 is to convert your VGA (RGBHV) signal to Component Video
(YPrPb). The unit automatically adjusts to the input scan format. There are
added bonuses that let you also simultaneously drive your VGA monitor,
decode SCART input sync, and a Special Sync mode accommodates a
Panasonic®Direct View HDTV monitor connected to RCA®DTV Set Top Box.
For PC VGA inputs, please refer to setting of your PC to the appropriate
resolution for your Composite Video display. See the PowerStrip guide at the
end of this manual.
Please be aware that LCD flat panel monitors do not recognize interlaced
formats such as 1080i.

STEP 2: Make your Input Connection:
• One VGA Video (RGBHV) input on DB15 connector
STEP 3: Make your Output Connections:
• One Component Video (YPrPb) output on three RCA female jacks which can
drive equal cable lengths up to 50 feet (be sure to terminate this output at the
end of the runs)
• If desired, use the VGA loop-through to simultaneously drive your VGA
monitor
STEP 4: Configure the Sync Select Switches (adjacent to the Component Video
output connectors) to suit your application:
QUICK SET-UP

Select input sync with Switch 1 between H and V drive, or SCART on H:
• Switch 1 ON (up): H and V drive VGA input (typical mode, RGBHV)
• Switch 1 OFF (down): SCART composite sync in on H
Select output sync with Switch 2 between H and V drive, or Special Sync mode:
• Switch 2 ON (up): Composite Sync out on YPrPb (typical mode)
• Switch 2 OFF (down): Special Sync out to accommodate a Panasonic®Direct
View HDTV monitor connected to RCA®DTV Set Top Box
STEP 5: Apply power to the unit:
KD-VTCA3
Model KD-VTCA3

• Use ONLY the external wall-plug power supply provided with your unit, +6
Volts @ 0.3 Amps, 110-240V AC, 50-60 Hz
• Connect the 1/8” mini-plug external power supply connector to your unit,
and plug the power supply into a power outlet
• The green Power-on LED (adjacent to the external power supply connector)
should be ON
STEP 6: Operation of your unit:
• Your VGA source should now drive your Component Video display and is also
available as a loop-through to a VGA monitor
