About this Manual
This manual contains information about the Extron
RGB 202 Rxi and RGB 202 Rxi VTG universal interfaces and on
how to operate and configure them.
About the RGB 202 Rxi xi xi xi xi and RGB 202 Rxi xi xi xi xi VTG
The RGB 202 Rxi is an analog computer-video interface with
300 MHz (-3dB) video bandwidth and Advanced Digital Sync
Processing™. It accepts two computer-video and two
unbalanced computer stereo audio inputs. It also features one
RGBHV, RGBS or RGsB output and one balanced, line level
stereo audio output. The RGB 202 Rxi VTG is identical to the
RGB 202 Rxi except that it also contains a built-in video test
generator (VTG).
Front panel controls, remote contact closure, or an RS-232
remote control system or computer can be used to select
between inputs.
Features
Features of both models
Flexible mounting options — The RGB 202 Rxi and
RGB 202 Rxi VTG can be rack mounted, mounted under a
desk or podium, or mounted through a desk or other
furniture with optional mounting kits.
Stereo audio — Unbalanced PC stereo audio inputs are output
as line level, balanced stereo audio.
Level (boost) and peaking controls — Separate front panel
controls compensate for signal losses from long cable
runs.
Horizontal and vertical centering controls — These front panel
controls allow separate horizontal and vertical centering
adjustments.
Digital sync processing — Using regular sync processing to
allow centering control (H-shift or V-shift) can create
problems with some digital display devices as a result of
the sync delay. Extron's ADSP™ (Advanced Digital Sync
Processing™) maintains a stable sync signal while
allowing centering control. These interfaces also provide
another option, DDSP™ (Digital Display Sync
Processing™), to ensure proper displays without altering
sync pulse timing or width. The sync processing type is
selected via a rear panel DIP switch.

Thirty memory presets — Thirty spaces are reserved in the
interface's memory for storing user-defined combinations
of horizontal and vertical position settings based upon
input signal scan rates. The interface automatically
recalls the position settings when it detects an input
signal with a matching scan rate.
LCD scan rate indicator — This backlit liquid crystal display
(LCD) indicates the horizontal and vertical sync rates, and
the minimum and maximum centering limits. A DIP
switch is provided for turning off the backlight.
MBC power jacks — These jacks provide power to buffered
monitor breakout cables.
75 ohm video termination switches — Rear panel DIP switches
provide a way to switch between high Z and 75 ohm
video input termination for systems where a local
computer monitor is not used.
RGBHV, RGBS, or RGsB outputs — Select the output format
via cabling setup and rear panel DIP switch.
Serration pulse switch — This DIP switch-selectable feature
adds or strips the serration pulses from the output signal
to make it compatible with digital display devices. Use
the serration pulse switch if flagging or bending occurs at
the top of the video display.
Sync polarity adjustment — Horizontal and vertical sync
output can either follow input sync polarity, or outgoing
sync can be forced to negative via a rear panel DIP switch.
Vertical sync pulse width adjustment — Vertical sync pulse
width can be adjusted via a rear panel DIP switch.
Remote control input selection — Connect a remote contact
closure keypad, an RS-232 control system, or a computer
to the rear panel RS-232 port to remotely control the
interface.
Vented metal enclosure — Vents in the enclosure keep the
interface cool and ready for use 24 hours a day, 7 days per
week.
Automatic sync stripping — Sync signals are automatically
stripped from the red, green and blue video input signals.
The interfaces output sync simultaneously as separate
horizontal and vertical sync and as composite sync, but
sync on green (SOG) can be selected via a rear panel DIP
switch.
