Introduction

Thank you for purchasing the KD-VA5 by Key Digital™, a state-of-the-art universal analog Video
Adapter. The KD-VA5 is the flexible solution you’ve been looking for to mix and match RGBHV
and Component Video (YPbPr) sources and displays. It also has many well-thought-out
features, including:

Allows you to connect RGBHV sources, such as from your PC, to Component Video (YPbPr)
displays:

Pass-through lets you simultaneously maintain connection to your RGBHV PC monitor

Allows you to connect Component Video (YPbPr) sources, such as from your Cable Box or
DVD player, to RGBHV displays:

Pass-through lets you simultaneously maintain connection to your HDTV Component
Video display

Supports most analog interlaced and progressive video formats, at 60 Hz or 50 Hz, such as
HDTV, NTSC, and PAL:

1080i (60 & 50 Hz)
720p (60 & 50 Hz)
480p (60 Hz)
576p (50 Hz)

576i (50 Hz, SCART only)
Uses RCA and HD-15 VGA female connectors, and supports cable runs up to 50 feet
Simple to operate with three configuration slide switches, and clearly labeled silk-screened

instructions and LEDs for status indication on the top cover
Intelligent Auto Sensing™ automatically switches from RGBHV-to-Component Video or

Component-to-RGBHV Video by sensing active sync on the “Y” Component Video signal
Supports sync on Y, separate H&V sync, as well as a variety of alternate sync formats,

including:

Sync on green, composite sync, or SCART
Performs no video processing other than RGBHV-to-Component Video or Component-to-

RGBHV Video conversions, ensuring perfect image quality from input to output

Useful Tips

It is suggested that you read and follow this entire Operating Manual. Some useful tips to keep
in mind when installing and using the KD-VA5:

Always test the full operation of your unit before final installation of cables behind
walls or ceilings.

Use ONLY the 5V, 1 Amp Power Supply provided with your unit.

“Component Video” means “YPbPr” with “Sync” usually provided on the “Y” channel.

KD-VA5 Intelligent Auto Sensing™ looks for active sync on the “Y” Component Video
source input, so if you are in the RGBHV-to-Component Video mode and want to view the
RGBHV source you must ensure there is no active sync on the “Y” channel.

You must set the three slide switches to correspond to the desired Sync settings. Follow
the instructions on the silkscreen cover of the unit, or read the details provided in this
Operating Manual.

Limit cable lengths to 50’ each, using high-quality cables of equal cable length.

The KD-VA5 supports only the following popular analog SD and HD video formats:
➔ 1080i (60 & 50 Hz),
➔ 720p (60 & 50 Hz)
➔ 480p (60 Hz)
➔ 576p (50 Hz)
➔ 576i (50 Hz, SCART only)

Take advantage of the “pass-through” feature to simultaneously connect Component and
RGBHV Video sources and displays.

Verify intended operation/configuration by observing the LEDs on the top of the unit and
the corresponding silkscreen explanations.

This video adapter is NOT a video processor or video scaler, so other than format
conversions between RGBHV and Component (YPbPr) Video, there is no further video
processing performed in the unit.

This video adapter does not support audio. You must handle your audio connections and
needs separately.

Other than Intelligent Auto Sensing™ feature, the KD-VA5 does not provide switching or
distribution capabilities. Only use each output to drive one video display, and do not daisy
chain the video inputs to any other product.
