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.
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 Rxixi
xixi
xi and RGB 202 Rxixi
xixi
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.

Vertical centering ( )— While viewing the displayed image,
rotate this control to move the image up or down on the screen.
During centering adjustment, the LCD displays V-SHIFT, and it
indicates the vertical shift minimum or maximum limit when
the centering limit has been reached. See the notes below.
4
Horizontal centering ( )— While viewing the displayed
image, rotate this control to move the image to the right or left
on the screen. During centering adjustment, the LCD displays
H-SHIFT, and it indicates the horizontal shift minimum or
maximum limit when the centering limit has been reached.
DDSP disables the interface’s vertical and horizontal
centering controls. If DDSP is set to On and either
centering control is rotated, N/A DDSP ON appears on
the LCD display.
To use the display device’s centering controls instead of
the interface’s centering, set the DDSP DIP switch to On.
The centering controls have no mechanical limits to
rotation. When the minimum or maximum limit of the
control is reached, the picture stops moving on screen.
Many projectors store centering information in their own
memories based on signal frequency. When a projector displays
video from input sources that have the same frequency, one
source’s images may not be centered. Using the interface’s
centering controls eliminates that problem.
Turning the centering control knobs not only moves the images,
but it also stores the horizontal and vertical centering settings in
separate memories for each selected input. The interface recalls
the centering settings each time an input is selected. Centering
adjustments only need to be set once for an application because
the settings are saved even when the power is off.

VTG output resolution and pattern selection switch
(RGB 202 Rxi VTG only) — Select a combination of display
resolution and video test pattern using this 16-position rotary
switch. Four different video test patterns are available for each
of the four resolutions offered by the RGB 202 Rxi VTG’s built-in
mini video test generator. See “Operating the VTG” in this
chapter for more information.

Level/boost control — This alters the video output voltage to
affect the brightness of the displayed
image. Adjust the level/boost control
while viewing the displayed image to set
the level/boost that provides best picture
quality.
If the interface receives a typical (0.7 volts p-p) analog computer
video input, the output will be as follows:
• At the minimum level setting (the counterclockwise limit of
this control), the interface will output video at 0.5 volts p-p.
• Unity level is 0.7 volts p-p, the same as the input signal.
Set the control to just before the boost area (indicated by
the red line) to output unity level video.
• At the maximum level setting (the clockwise limit of this
control), the interface will output video at 1.45 volts p-p.
Select a setting in the boost range (0.7 volts and above),
indicated by the red line, to compensate for the decrease in
signal level that occurs when the signal passes through long
cables.
Set the boost at 100% (the maximum level) for cable lengths over
500 feet for all computer signals of 15 kHz to 135 kHz.
2
Peaking (Peak) control — Peaking affects the sharpness of a
picture. Increased peaking can compensate for detail (mid- and
high-frequency) loss from low bandwidth system components
or capacitance in long cables. The minimum setting (at the

202 (interface)/VTG selection switch
(RGB 202 Rxi VTG only) — Use this switch to select the output
signal’s source
202 = The image from the interface (from input 1 or
input 2) will be displayed.
VTG = A test pattern generated by the VTG (video test
generator) will be displayed.
When this switch is set to VTG, signals from input1 and
input 2 are ignored; the interface’s internal VTG
provides a test pattern in place of the computer video
input. Input selection (selection of input 1 or input 2)
cannot be performed until the 202/VTG selection switch
is set to 202.
7
LCD display — This backlit LCD shows the horizontal and
vertical scanning frequencies. While centering adjustments are
being made, the LCD displays H-SHIFT or V-SHIFT, and it
indicates the horizontal or vertical shift minimum or maximum
limit when a centering limit has been reached. If DDSP is on
and the horizontal or vertical centering control is rotated, the
LCD displays N/A DDSP ON.
While the VTG is active (RGB 202 Rxi VTG only), the LCD
displays the current format, resolution and scan rate settings.
See the “LCD Display” section for details.
The backlight turns on at power-up, and it remains on for
15 seconds if a signal is not present at the selected input. If a
signal is present, the backlight will remain on at all times.
However, if the rear panel No Backlight DIP switch is set to On,
the backlight will turn on for only three seconds at power-up,
then it will remain dark even when an active signal is present.

Input selection switch and LEDs — Use this toggle switch to
select between input 1 and input 2. The LED corresponding to
the selected input lights, and the switch returns to the center
position automatically.
A remote contact closure switch, a computer, or an RS-232
control system connected via the rear panel 9-pin D port can be
used instead of this switch.

serration pulse output, sync polarity, vertical sync width, video
termination (high Z/75 ohm), and backlight illumination.
The default for all DIP switches is Off (down).
1 — DDSP (Digital Display Sync Processing)
This feature may be necessary for digital display devices
such as LCD, DLP (digital light processing) and plasma
displays. Use this option if the image is not displayed
properly after other options, such as serration pulse and
video termination changes, have been explored.
On — The interface uses DDSP instead of ADSP.
DDSP does not process the sync signal.
DDSP disables horizontal and vertical centering
controls.
Off — The interface performs sync processing operations,
such as centering, with ADSP.

2 — SOG (sync on green)
On — The interface outputs sync on green.
Off — The interface outputs both separate horizontal and
vertical sync (on the H and V connectors) and
composite sync (on the S connector) for RGBHV or
RGBS, respectively.
3 — Serr (serration pulse) — Many LCD and DLP projectors
and plasma displays, must have serration pulses removed
from the sync signal in order to be displayed properly.
Flagging or bending at the top of the video image is a sign
that the serration pulses should be removed.
On — The interface outputs serration pulses in the vertical
sync interval.
Off — The interface does not output serration pulses.
4 — Neg Sync — This switch controls sync polarity.
On — Both the horizontal and the vertical sync signals
are forced to negative polarity on output.
Off — Output sync polarity follows (is the same as) input
polarity.
5 — V Sync Width (vertical sync pulse width) — For some
digital display devices, if no picture appears, the picture
cuts in and out, or it is scrambled, try adjusting the output
vertical sync pulse width or switching from ADSP to DDSP.
On — The vertical sync pulse is narrow.
Off — The vertical sync pulse is wide.
6 & 7 — 75 Ohm (video input termination) — DIP switches
6 and 7 provide termination for video inputs 1 and 2,
respectively. Video termination can be accomplished by
using a laptop breakout cable, by connecting a termination
adapter or a local monitor to a monitor breakout cable
(MBC), by using an MBC buffer cable, or by setting a
termination switch on the interface.
DIP switches 6 and 7 provide a termination method to
prevent blooming when a monitor breakout cable is used
but no local monitor or termination adapter is connected.
On — The interface provides 75 ohm video input
termination.
Off — The interface provides high Z (high impedance)
video input termination.
8 — No Backlight — This switch controls illumination of the
LCD backlight.
On — The LCD backlight is off, except for three seconds
at power-up.
Off — The LCD backlight is on while a signal is present at
the selected input.

Most laptop or notebook computers have an external
video port, but they require special commands to output
the video to that connector. Also, laptops’ screens shut
off once that port is activated. See the computer’s user’s
guide for details, or contact Extron for a list of laptop
keyboard commands.
2. Connect the unbalanced stereo audio sources (computer or
other devices such as a CD player) to
the front panel.
Wire the audio jack as shown here.
3. Connect the display device’s (projector’s, monitor’s)
coaxial BNC cable to the rear panel BNC connectors.
For RGBHV (separate H and V sync) output,
connect the cables as shown at left.
For composite sync (RGBS), connect the sync
cable to the connector labeled “S”.
For sync on green (SOG, RGsB), connect the
cables as shown here, and also select the SOG
option on the rear panel DIP switch.
4. Connect the local monitors to the monitor breakout cables
if they were used in step 1 to connect the computers to the
interface. Set the 75 ohm DIP switches to On if no local
monitor is used with a connected MBC cable.
5. Connect an audio device, such as powered speakers, to the
rear panel stereo audio output connector for balanced or
unbalanced audio output. Following the wiring guide
shown below, insert the wires into the appropriate
openings in the captive screw connector. Tighten the
screws on top to fasten the wires, then insert the wired
audio connector into the audio output connector on the

LCD Display
The RGB 202 Rxi and RGB 202 Rxi VTG’s front panel LCD
display serves two main functions: to display the scanning rates
of the input signal, and to indicate the horizontal and vertical
centering limits. During VTG operation, the RGB 202 Rxi VTG’s
LCD displays the VTG format, resolution and refresh rates.
LCD screen backlight
The LCD screen lights for 15 seconds at power-up, and it stays
backlit as long as an input signal is present at the selected input.
To force the backlight to remain off at all times except at power-
up, set the rear panel No Backlight DIP switch to On.
See page 2-11 for details.
Scan rate indication
When the interface is powered on, the LCD lights for 15 seconds
while it determines whether an input sync signal is present. If
the No Backlight DIP switch is set to On, the LCD lights for
three seconds only.
• If the interface does not detect an input sync signal, the
LCD goes dark and displays “NO SIGNAL” until the
interface receives an active sync signal.
• If the interface detects an input sync signal, the LCD
displays the horizontal and vertical scan rates (sync
frequencies) in the following format:
Hxxx.xxk
Vxxx.xHz
The first line shows the horizontal rate in kilohertz, and
the second line shows the vertical rate in Hertz.
Centering
While the vertical ( ) or horizontal ( ) centering (shift)
controls are being adjusted, the LCD displays “H-SHIFT” or
“V-SHIFT”, respectively. That message remains on the LCD (in
place of the scan rates) until the centering control has been
inactive for 3 seconds. When a centering control reaches its
minimum or maximum limit, the LCD displays “MIN” or
“MAX” on the line below “H-SHIFT” or “V-SHIFT”.
If the centering controls are no longer active, the centering
settings are saved, and the LCD displays the current scan rates.
If the DDSP DIP switch is set to On and a centering control is
rotated, the LCD displays N/A DDSP ON, and the image does
not shift on screen.
Operating the VTG (RGB 202 Rxixi
xixi
xi VTG only)
The RGB 202 Rxi VTG includes a limited video test generator.
The VTG creates and outputs standard test patterns at fixed
formats and resolutions so that a system can be set up and
tested even when an input computer is not available.
To use the VTG, follow these steps:
1. Set the front panel 202/VTG selection switch to VTG.
2. Select an appropriate combination of output resolution
and test pattern using the 16-position rotary switch on the
front panel. Four different video test patterns are available
for each of the four resolutions. Select the test patterns by
rotating the switch within the appropriate resolution
quadrant. The LCD displays the selected VTG format, the
resolution, and then the scan rates.
The test patterns are shown below.
Left to right: crosshatch, H-pattern, 8 split-level
grayscale, and 8 color bar test patterns
The four available resolutions are shown below.

6. If the image appears and is stable, but it has ghosting or
blooming, check the high Z/75 ohm video input
termination. If changing the termination doesn’t solve the
problem, try using a different input cable.
7. If the picture is faint or cuts out and the signal is weak, the
video input may be double-terminated. If a local monitor
or a termination adapter is attached to the input’s monitor
breakout cable, or if a laptop breakout cable is used, make
sure that the 75 ohm video input termination DIP switches
are set to Off (for high Z termination).
8. If the picture from a new source computer does not seem
correctly centered, the input position memory presets
might require resetting. To reset the input position
memories, do the following:
a. Unplug the interface’s AC power cord.
b. Hold the input selection switch up (toward input 1)
while reconnecting the power cord to the interface
and the power source
c. Select the appropriate input, and adjust the
horizontal and vertical centering.
9. If the image still does not display correctly, call Extron’s
customer support hotline.
If the interface does not respond to controls
1. If the picture does not move on screen when the horizontal
and vertical centering controls are rotated, DDSP is in use.
Set the DDSP DIP switch to Off.
2. If the RGB 202 Rxi VTG does not switch between inputs
when a remote control is used, the front panel 202/VTG
toggle switch might be set to VTG. Use the switch to select
202 in order to use a remote control.
When the 202/VTG switch is set to VTG, signals from
input1 and input 2 are ignored; the interface’s internal
video test generator provides a test pattern in place of the
computer video input. Input selection (selection of
input 1 or input 2) cannot be performed until the
202/VTG selection switch is set to 202.
Troubleshooting
Turn on the input devices (computer, audio device) and output
device(s) (projector, monitors, speakers). The image should now
appear on the screen, and sound should be audible.
If the image does not appear or there is no sound
1. Ensure that all devices are plugged in.
2. Make sure that each device is receiving power. The
interface’s front panel LED lights if the interface is
receiving power and an active sync signal.
3. Check the cabling and the audio connector wiring and
grounding, and make adjustments as needed.
4. Verify that the 75 ohm video input termination DIP
switches have been set correctly.
5. For digital display devices (including LCD, DLP and
plasma devices), try turning DDSP on or off using the rear
panel DIP switch.
6. To test the system setup and output, substitute a video test
generator for one of the computer inputs. Use the VTG
that is built into the RGB 202 Rxi VTG, or use a stand-alone
VTG with the RGB 202 Rxi. To use a stand-alone VTG,
unplug the input/output devices’ and interface’s power
cords, replace the video source with a VTG, then reconnect
power cords to restore AC power.
7. Call Extron’s customer support hotline if needed.
If the image is not displayed correctly
1. If the output image looks too green, the sync on green
(SOG) DIP switch may be set to On, and the display device
may not be configured to handle SOG signals.
Set SOG to Off.
2. If the picture bends or flags at the top of the screen, set the
serration pulse DIP switch to Off.
3. For a display device that experiences intermittent glitches,
try turning DDSP on or off using the rear panel DIP
switch.
4. If the picture “hangs off” the edges of the screen, adjust the
centering controls ( , ).
5. If the edges of the image seem to exceed their boundaries
or if thin lines and sharp edges look thick and fuzzy, try
changing the Level/Boost or Peak Control settings. If the
image is too bright, decrease the boost or peaking level.

RECONFIG
When a change is made via a front panel control or another
operation occurs that must be written to a new memory block,
the interface sends the reconfiguration message. No response is
required from the RS-232 host, but the host may request a new
status listing via the request information command (I/i). See
the command/response table in this chapter for details.
Chn
X2
The input number has been changed or,
for the RGB 202 Rxi VTG, the VTG has been turned on or off.
Error responses
When the interface receives a valid SIS command, it executes the
command and sends a response to the host device. If the
interface is unable to execute the command because the
command is invalid or it contains invalid parameters, it returns
an error response to the host.
The error response codes and their descriptions are as follows:
E01 – Invalid input number (the number is too large or small;
occurs when attempting to select VTG mode via RS-232)
E06 – Invalid input selection (occurs when selecting an input when
the RGB 202 Rxi VTG is set to VTG mode)
E10 – Invalid command
E13 – Invalid value (the number is out of range/too large)
Using the command/response table
The command/response table lists valid command ASCII codes,
the interface’s responses to the host, and a description of the
command’s function or the results of executing the command.
Lower case characters are acceptable in the command field only
where indicated. The ASCII to HEX conversion table below is
for use with the command/response table.

•
There are three ways to control input selection and centering
features of an RGB 202 Rxi /RGB 202 Rxi VTG interface: by using
the front panel controls, by using an RS-232 remote control
device, and by using a contact closure keypad.
RS-232 Programmer’s Guide
The interface can be remotely controlled via a host computer or
other device (such as a control system) attached to the rear panel
9-pin D RS-232 connector. The protocol is 9600 baud, 1 stop bit,
no parity, and no flow control.
The control device (host) can use either Extron’s Simple Instruc-
tion Set (SIS) commands or the graphical control program for
Windows. RS-232 control software is included with the interface.
The rear panel RS-232 9-pin D female
connector has the following pin assignments:
Pin RS-232 function Contact closure Description
1 – Input 1 Select input #1
2 Tx – Transmit data
3 Rx – Receive data
4 – Input 2 Select input #2
5 Gnd Gnd Signal ground
6 – – Not used
7 – – Not used
8 – – Not used
9 – – Not used
Host-to-interface communications
SIS commands consist of one or more characters per field. No
special characters are required to begin or end a command
sequence. When a command is valid, the interface executes the
command and sends a response to the host device. All respon-
ses from the interface to the host end with a carriage return and
a line feed (CR/LF = ), which signals the end of the response
character string. A string is one or more characters.
Interface-initiated messages
When a local event such as a front panel or contact closure
selection or adjustment takes place, the interface sends a
message to the host. No response is required from the host. The
interface-initiated messages are listed here (underlined).

Control Software for Windows
The included graphical control software for Windows offers
another way to control the interface via RS-232 in addition to the
Simple Instruction Set commands listed on page 3-4. The
control software is compatible with Windows 3.1x, Windows 95/
98, and Windows NT. The RGB 202 Rxi and RGB 202 Rxi VTG
use version 2.0 or higher of Extron’s RGB 302/304/202 Control
Program, which is included with these interfaces.
Installing the software
The control program is contained on a 3.5-inch diskette, and it
can run from the floppy drive. However, it is more convenient
to run the program from the hard drive.
To install the software onto the hard drive, run SETUP.EXE from
the floppy disk, and follow the instructions that appear on the
screen. The program requires approximately 1 MB (megabyte)
of hard disk space.
By default the installation creates a C:\RGB302 directory, and it
places two icons (RGB 302+304+202 Control Pgm and RGB 302+
304+202 Help) into a group or folder named “Extron Electronics”.
Using the software
To run the control program, follow these steps:
1. Double-click on the RGB 302 + 304 + 202 Control Pgm icon
in the Extron Electronics group or folder,
or on the Rgb302.exe icon in the
C:\RGB302 directory. The Comm menu
will appear on the screen.
2. Click on the comm port that is connected to the interface’s
RS-232 port. The control software will
“look for” the interface at that port and
read its configuration.
The control program window (shown
at left) will appear and display current
settings.
For information on program features, press the F1 computer key
or click on the Help menu from within the
control program, or double-click on the RGB
302+304+202 Help icon in the Extron Electronics
group or folder.
