RGB 201 Rxi Universal Interface • Installation and Operation
• At the maximum level setting (the clockwise limit of this
control), the interface outputs video at 1.45 volts p-p.
Select a setting in the boost range (0.7 volts and above),
to compensate for the decrease in signal level that occurs
when the signal passes through long cables.
Set the boost at 100% (the maximum level) for cable
lengths over 500 feet for all computer signals of 15 kHz to
150 kHz.
b
Peaking (Peak) control — Peaking affects the sharpness of a
picture. Increased peaking can compensate for detail (mid- and
high-frequency) loss from low bandwidth system components
or capacitance in long cables. The minimum setting (at the
counterclockwise limit) provides no peaking. The maximum
setting (at the clockwise limit) provides 100% peaking. Adjust
this control while viewing the displayed image to obtain the
optimum picture sharpness.
Centering controls
Many projectors store centering information in their own
memories based on signal frequency. When a projector displays
video from different input sources that have the same frequency,
one source’s images may not be centered. Using the interface’s
centering controls eliminates that problem.
c
Vertical centering (
{
) — While viewing the displayed image,
rotate this control to move the image up or down on the screen.
During centering adjustment, the LCD displays V-SHIFT, and
it indicates the vertical shift minimum or maximum limit when
the centering limit has been reached. See the notes below item
4
.
d
Horizontal centering (
[
) — While viewing the displayed
image, rotate this control to move the image to the right or left
on the screen. During centering adjustment, the LCD displays
H-SHIFT, and it indicates the horizontal shift minimum or
maximum limit when the centering limit has been reached.
N
DDSP disables the interface’s vertical and horizontal
centering controls. If DIP switch 1 (DDSP) is set to On
and either centering control is rotated, the LCD displays
N/A DDSP ON.
To use the display’s centering controls rather than the
interface’s controls, set the DDSP DIP switch to On.
