Smart Avi VCA-100 - Manual (Page 2)

Introduction
The VSA-100 is Smart Adjustor that compensates for skew
delay between any Red, Green Blue signals transmitted
over a twisted pair cable. Any CAT5 or CAT6 cable can
introduce delay between the pairs, due to the varying
lengths of each pair. The delay causes color distortion
and improper alignment. Skew delay increases as the
length of the cable increases. The VSA-100 corrects the
skew of each color independently, making it the perfect
skew correction tool.
Installation
1.
Turn off the receiving video extender, the display
and the VSA-100.
2. Connect the included male to male VGA cable to
the receiving video extender.
3. Connect the other end of that male to male VGA
cable to the input of the VSA-100.
4. Connect the VGA display to the output of the VSA-
100.
5. Power on the receiving video extender and the
display.
6. Connect the power cord to the VSA-100.
Using the VSA-100
The skew of the signal is adjusted using the three color
channels of VGA which are Red, Green and Blue. There
are six buttons on the front of the VSA-100, two for
each color. When looking at the image on the display,
choose the color that looks most out of line compared
to the others. For example, if the image looks like it
has green fringe, choose the green adjustment. While
changing the skew of a particular color channel, watch
the image for changes in alignment. It is best to choose
one color that the other two will be aligned to. For
example if green was the best aligned color, you would
adjust only the blue and red to compensate. Align
the colors in the image until there is no visible fringe
and the image looks clear. The VSA-100 will retain this
setting even after it is powered off.

What is Skew Delay?
TRANSMITTER TWISTED PAIR CABLE RECEIVER
CAT5 and CAT6 cables have pairs of wires that are
twisted at different rates, and some pairs are longer
than others. Because RGB signals are sent along
different pairs, there is a delay in the arrival of the
signals at the receiver. This results in color separation
and degradation of the image quality. The longer the
cable, the worse the skew delay.
