Power on all devices.

If your image is flickering or blinking, adjust the
Gain and EQ knobs to improve the cable skew. It is
suggested to begin by adjusting the EQ first then the
Gain according to the video displayed on the screen.
8.
RGB skew adjust
feature allows skew compensation
among red (R), green (G), and blue (B) signals due
to long transmission distance or low quality cabling.
Start by adjusting the
RGB selector
rotary dial to
choose R/G/B color channel, then use the
-
or
+
RGB skew adjust
push buttons to decrease or
increase, respectively, the delay of the corresponding
R/G/B color channel.
Notes
1.
All transmission distances are measured using
Belden 1583A CAT5e 125MHz Solid UTP cable and
ASTRODESIGN Video Signal Generator VG-859C.
The transmission distance is defined as the distance
between the video source and the VGA display.
2.
Transmisson length is affected by the type of CAT5/
6 cables, the type of VGA sources, and the type of
VGA display. Testing results show that solid UTP
cables (normally found in 300m [1000ft] bulk form)
can transmit longer distances than stranded UTP
cables. Shielded STP cables are better suited than
unshielded UTP cables. Solid UTP CAT5e cabling
returns longer tranmission distances than stranded
STP CAT6 cables. For longer transmission distance,
solid UTP/STP cables are your best choice.
3.
To reduce the interference among the unshielded
twisted pairs of wires in the LAN cable, you can use
shielded LAN cables to reduce EMI problems.
