Front Panel Operation
Auto Power – Senses computer power and automatically turns the
RGB 202xi power O .

Level Boost – Similar to a contrast control, this control raises and lowers the
output signal level from the original input level. e.g. a VGA input of 0.7v
peak-to-peak (p-p) can be adjusted for an output level of 0.3 to 0.8v p-p
(without boost). Within the boost (red) range, the output can be raised to
1.25v p-p.
Peak Control – Similar to a sharpness control, this control compensates for
mid and high frequency bandwidth response in data monitors and
projectors, and for signal losses due to cable capacitance. A sharper
image will be seen from most computers, regardless of cable length. For
long cables, the setting will probably be above the 50% level. Use your
visual judgement when using this adjustment.
Blue Enhance – Used with TTL signals (Input #1), allows the mixing of blue
with green for displaying text that is easier to read (blue-green color).
V Centering (vertical shift) – Moves image up or down on the display
screen. (Not active if DIP switch #1 is On) Memory stores settings to
keep image centered when switching inputs.
H Centering (horizontal shift) – Moves image left or right on the display
screen. (Not active if DIP switch #1 is On.) Memory stores settings to
keep image centered when switching inputs.
LCD Screen – Alternately displays the horizontal and vertical frequencies of
the selected input.
H LED (red) – Lights when the LCD is displaying the horizontal
frequency of the selected input.
V LED (green) – Lights when the LCD is displaying the vertical
frequency of the selected input.
Input Switch – Used to select Input #1 or #2 (both video & audio) for output
from the RGB 202xi. (If in the #1 position, a constant contact switch may
be connected through the rear panel for remote switching.)

Reference Information Introduction • Features and Specifications
LCD Sync Processing – Exclusive to Extron, our LCD sync
processing makes the RGB 202xi work with CRT and
LCD based presentation displays.
Input Switch – The RGB 202xi interface can be connected
to the outputs of two computers at the same time, making
it a two-input switcher as well as an interface. The Input
switch is used to select which input source (#1 or #2) will
be displayed on the connected monitor or projector. Both
inputs are universal.
Termination Switches – These switches allow for 75 ohm
termination of the connected computer for either of the
two inputs. With this feature, an external termination
adapter is not required when using an Analog type
computer without an external local monitor (i.e., a
Laptop).
Automatic Sync Stripping – Sync is automatically stripped
off any incoming signal with sync on the red, green and
blue video channels. If desired, it can be added back to
the green output signal by the use of a dip switch, or Auto
Sync output detection.
Auto-Sync Output Detection – Automatically senses the
impedance on each BNC output, determines which ones
are being used and sends the proper sync output.
Audio Interface – The RGB 202xi includes a PC/computer
audio (600 ohm) to line-level audio (balanced) converter.
For computers that have a sound card, the audio
interface will select that audio input together with the
video (audio follow). The audio output can be connected
to an external stereo system.
Two-Input Switching – The RGB 202xi may be used as a
two input (one Analog/ECL and one Analog/TTL)
switcher. Input selecting can be done by the front panel
toggle switch or with an optional external switch plugged
into the rear panel remote connector. Audio input is
switched with video.
Local Monitor Compatibility – Using an MBC (Monitor
Breakout Cable) with the RGB 202xi allows for computer
monitor and large screen display image to operate at the
same time. This allows the presenter, or computer
operator to use the computer's (local) monitor while the
audience watches on the large screen.
