About this Manual
This manual contains information about the Extron RGB 203 Rxi
and RGB 203 Rxi VTG universal interfaces and on how to
operate and configure them.
About the RGB 203 Rxi and RGB 203 Rxi VTG
The RGB 203 Rxi (figure 1-1) is an analog computer-video
interface with 300 MHz (-3dB) video bandwidth, Advanced
Digital Sync Processing™ (ADSP™), and Digital Sync
Validation Processing™ (DSVP™). It accepts three computer-
video and two unbalanced computer stereo audio inputs (Input
3 is video only). It also features a local monitor output, an
RGBHV, RGBS or RGsB output and a balanced, line level stereo
or mono audio output. The interface features horizontal and
vertical centering and level boost and peaking. The RGB 203
Rxi VTG is identical to the RGB 203 Rxi except that it also
contains a built-in video test generator (VTG).
Front panel controls, remote contact closure, autoswitching, or
an RS-232 remote control system or computer can be used to
select among inputs and to shift the output image horizontally
and vertically.
The interfaces are rack-mountable and furniture-mountable and
have an internal switching power supply for worldwide power
compatibility.
Features
Flexible mounting options — The RGB 203 Rxi and
RGB 203 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 — The interface processes unbalanced PC stereo
audio inputs as a line level, balanced stereo or mono
audio output.
Level (boost) and peaking controls — Separate front panel
controls compensate for signal losses from long cable
runs.
Horizontal and vertical centering controls — Separate front
panel controls allow separate horizontal and vertical
centering adjustments.

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 option 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.
Digital Sync Validation Processing — In critical environments
or unmanned, remote locations, it is vital to know which
sources are active. Extron's exclusive DSVP confirms that
input sources are active by scanning all sync inputs for
active signals. DSVP provides instantaneous frequency
feedback for composite sync or separate horizontal and
vertical sync signals via the interface's Remote port.
