Introduction

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 R

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.

xi and RGB 202 R

xixi

xixi

xi VTG

xixi

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.

Installation and Operation

Installation and Operation 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 202 Rxi and RGB 202 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.

Install the rubber feet for tabletop use, or install the

2

appropriate brackets and furniture or rack mount the
interface. See “Mounting the Interfaces” in this chapter.

Attach the input (computers), output (display, local

3

monitor and audio), and remote control cables. See
“Cabling” in this chapter.

Set the rear DIP switches. Use the “Rear Panel” section of

4

this chapter as a guide.

Connect power cords and turn on the devices: output

5

devices (projector, monitors, speakers), remote control
device, interface, and source computers.

Select an input from the front panel toggle switch or the

6

remote control (keypad, system, or PC).

Tabletop/desktop placement

For tabletop or desktop placement only, install the self-adhesive
rubber feet/pads (provided) onto the four corners of the bottom
of the interface enclosure.

Under-desk mounting

1. Attach the optional under-desk mounting brackets
(part #70-077-01) to the interface with the six machine
screws (provided in the mounting kit), as shown below.

2. Hold the interface with attached brackets against the
underside of the desk or other furniture. Mark the location
of holes for screws on the desk.

3. Drill 1/4” (6.4 mm) deep, 3/32” (2.38 mm) diameter pilot
holes in the table or desk at the marked screw locations
from the underside/inside (concealed side) of the
furniture, where the interface will be located.

4. Insert the four wood screws into the pilot holes. Fasten
each screw into the installation surface until just less than
1/4” of the screw protrudes.

5. Align the installed screws with the slots in the mounting
brackets, and place the interface against the surface, with
the screws through the bracket slots.

6. Slide the interface slightly forward or back, then tighten all
four screws to fasten it in place.

The image should now appear on screen, and sound

7

should be audible. If not, ensure that all devices are
plugged in and receiving power. Check the cabling and
switch settings, and make adjustments as needed. Select a
different input (or the VTG) to check for a picture and
sound.

If problems persist, see “Troubleshooting” in this chapter,
then call Extron’s customer support hotline, if needed.

Adjust horizontal and vertical centering, and also level

8

and peaking to obtain the best picture.

For the RGB 202 Rxi VTG, set up and test the VTG. See
