Introduction

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 computer­video 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.

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.

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 positive or negative via an internal
jumper.

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 Remote port to remotely control the
interface.

Executive mode — Locks out front panel control of horizontal

and vertical shift and input selection (with the exception
of VTG mode).

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 normally 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.

Video test generator (RGB 203 Rxi VTG only) — The VTG

version of the RGB 203 Rxi includes a 4-resolution (VGA,
SVGA, XGA, and SGI), 4-pattern video test generator to
simplify system setup and testing.

Installation and Operation

Installation Overview

This is an overview of the installation process. You will find
detailed installation and operation instructions in this chapter.

To install and set up the RGB 203 Rxi and RGB 203 Rxi VTG
interfaces, follow these basic steps:

Turn all of the equipment (computers, remote controls,

1

interface, projector/monitor, local monitor, and speakers
or other audio device) off. Disconnect the power cords
from the power source.

Sync polarity, video clamp, and VTG timer
require opening the interface’s case and should be done
before the interface is mounted.

If you want the interface to always output positive sync or

2

negative sync, rather than following the input sync
polarity, open the interface and shift internal jumpers as
necessary. See Internal Configuration and its subsection,
Sync polarity jumpers, in this chapter.

If you want to clamp the sync timing of the video output

3

to the sync tip rather than the back porch, open the
interface and shift an internal jumper. See Internal
Configuration and its subsection, Video clamping jumper, in
this chapter.

RGB 203 Rxi VTG only, if you want the built-in mini VTG

4

to continuously output the selected test pattern rather
than time out after 5 minutes, remove an internal jumper.
See Internal Configuration and its subsection, VTG timeout
(RGB 203 Rxi VTG only), in this chapter.

Install the rubber feet for tabletop use, or install the

5

appropriate brackets and furniture or rack mount the
interface. See Mounting the Interface in this chapter.

configuration

For the RGB 203 Rxi VTG, set up and test the VTG. See

10

Operating the VTG in this chapter.

Internal Configuration

The interface is factory configured to output RGBHV or RGBS
video whose sync follows the input and that is clamped to the
back porch. The interface can be configured to output positive
or negative sync or to clamp on the sync tip. The timeout
functions of VTG models can be turned off. All of these
reconfigurations require opening the interface’s case.

1. Remove the three screws on each side and the two screws

on top of the cover (figure 2-1).
