Figure 1. Typical Application for the RGB 203 Rxi
The RGB 203 Rxi is an analog computer-video interface with 300 MHz (-3 dB) video
bandwidth. It comes in two models:
z RGB 203 Rxi with ADSP
z RGB 203 Rxi with EDID Minder
™
®
Both models have Digital Sync Validation Processing (DSVP™). They accept three video and
two unbalanced stereo audio inputs (input 3 is video only). They provide a local monitor
output (RGBHV, RGBs, or RGsB) and balanced, line level stereo or mono audio output. They
also allow control of horizontal and vertical centering, level boost, and peaking.
Front panel controls, remote contact closure, autoswitching, or an RS-232 remote control
system can select among inputs and can be used to shift the output image horizontally or
vertically.
The interfaces are rack-mountable and furniture-mountable and have an internal switching
power supply for worldwide power compatibility.
RGB 203 Rxi • Introduction 1
Features
EDID Minder — The Extron EDID Minder ensures the resolution of the video source signals
is compatible with the display devices.
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.
The Extron ADSP option maintains a stable sync signal while allowing centering control.
Digital Display Sync Processing (DDSP™) — This feature 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 (DVSP) — In critical environments or unmanned,
remote locations, it is vital to know which sources are active. The exclusive Extron 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 Remote port of the interface.
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.
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.
Serration pulse selection — This DIP switch selectable feature adds or strips the serration
pulses from the output signal to make it compatible with digital display devices.
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.
Vertical sync pulse width adjustment — Vertical sync pulse width can be adjusted via a
rear panel DIP switch.
RGBHV, RGBS, or RGsB outputs — Select the output format via cabling setup and rear
panel DIP switch.
Stereo audio — The interface processes unbalanced PC stereo audio inputs as a line level,
balanced stereo or mono audio output.
Horizontal and vertical centering controls — Separate front panel controls allow
separate horizontal and vertical centering adjustments.
Level (boost) and peaking controls — Separate front panel controls compensate for
signal losses from long cable runs.
Thirty memory presets — Thirty spaces are reserved in the memory of the interface 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.
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.
Front panel security lockout (Executive mode) — Locks out front panel control of
horizontal and vertical shift and input selection.

The interface is factory configured for the output sync to follow the input sync. To force
positive or negative sync, reconfigure the jumpers as follows:
1. Locate jumper blocks J6, J7, and J20 on the printed circuit board (see figure 7).
2. For sync follow (output sync polarity identical to the input sync), remove the
jumper from block J20.
3. For positive or negative sync, install a jumper in block J20 and configure J6 and J7 as
follows:
a. Vertical sync — For positive sync, install a jumper in jumper block J7. For negative
sync, remove the jumper from jumper block J7.
b. Horizontal sync — For positive sync, install a jumper in jumper block J6. For negative
sync, remove the jumper from jumper block J6.
Video Clamping Jumper
The interface is factory configured to clamp the sync timing to the back porch. To clamp the
sync timing to the tip of the sync pulse, reconfigure the jumper as follows:
1. Locate J11 on the printed circuit board (see figure 7).
2. Set the jumper between pins 1 and 2 for sync timing clamped to the back porch.

a Level and Boost control — The Level and Boost control alters the video output voltage
to affect the brightness of the displayed image. Adjust the
knob while viewing the displayed image to set the level/boost
that provides the best picture quality.
For a typical (0.7 Vp-p) analog computer video input, adjust
the output is as follows:
z At the minimum level setting (the counterclockwise limit of this control), the
interface outputs video at 0.5 Vp-p.
z Unity level is 0.7 Vp-p, the same as the input signal. Set the control to just before
the boost range (indicated by the red line on the interface, the shaded area on the
illustration at right) to output unity level video.
z At the maximum level setting (the clockwise limit of this control), the interface
outputs video at 1.45 Vp-p.

Select a setting in the boost range (0.7 volts and above) 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 150 kHz.
b 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
counterclockwise limit) provides no peaking. The maximum setting (at the clockwise
limit) provides 100% peaking. Adjust this control while viewing the displayed image to
obtain the optimum picture sharpness.
Centering Controls
Many projectors store centering information in their own memories based on signal
frequency. When a projector displays video from different input sources that have the same
frequency, the image from one of the sources may not be centered. Using the centering
controls of the interface eliminates that problem.

Centering memory
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.
RGB 203 Rxi • Operation 11
EDID Minder Controls
Video sources communicate with the output device through the bi-directional Extended
Display Identification Data (EDID) communication protocol. The output device then produces
a signal with a resolution that is compatible with the display device.
The Extron EDID Minder feature maintains continuous EDID communication with the
attached sources and ensures that the video sources power up correctly and maintain a
proper video output, even if the display is off or a new monitor is connected to the output.
e Record button and LED — The recessed Record button is used to record
the EDID information provided by the current display device. An LED provides
feedback about the current status when the Record button is used. The
Record button has` three functions:
z Record EDID information from a display device
z Erase user-recorded EDID information
z Restore rmware to factory default
Record EDID information
To record EDID information, follow the following instructions:
1. Turn the EDID rotary switch to position 0 (see g on page 13).
2. Connect the display device to the local monitor output connector (see “Rear Panel
Connections” on page 3) and power on the display.
3. Press and release the recessed Record button. The LED flashes red slowly three times
while the EDID information is stored. When the recording is complete, the LED returns
to a solid green. At that time, the display device can be switched off and disconnected.
The EDID information is stored in memory and can be retrieved by setting the rotary
switch to 0. The information is retained until it is overwritten or erased.
RECORD
Erase user-recorded EDID information
To delete user-recorded EDID information, follow these instructions:
1. Turn the EDID rotary switch to position 0 (see g on page 13).
2. Press and hold down the Record button until the LED flashes red quickly five times.
When the old values have been deleted, the LED returns to a solid green. After the reset,
the user-recorded value is deleted.
Restore rmware to the factory default
To restore firmware to the factory-installed version, follow these instructions:
1. Disconnect power from the interface.
2. Press and hold the Record button while reconnecting the power. The LED flashes red
slowly three times. After the factory default firmware is restored, the LED returns to solid
green.

1. Connect the RGB 203 Rxi to the source. Do not switch on the source device yet.
2. Set the rotary switch to 0.
3. Power on the source device.
NOTE: By default, setting 0 on the rotary switch has no EDID information saved to it.
The user must save EDID to this location before it can be used.
Using pre-programmed EDID information
Positions 1 to E select from among 14 commonly used output resolutions that have been
preset at the factory. Position 2 (1024x768) is the default setting, to ensure the unit works as
shipped. See the table on page 13 for the resolution associated with each position on the
dial. To use one of the pre-defined EDID files:
1. Connect the RGB 203 Rxi to the source. Do not switch on the source device at this time.
2. Set the first DIP switch (f) to the required frequency (50 or 60 Hz).
3. Set the rotary switch to the required value (see the table on page 13).
4. Power on the source device.
Using pass-through EDID information from the local monitor
Position F passes through EDID information from a local monitor. To use this information:
1. Turn the EDID rotary switch to position F (see g on the previous page).
2. Connect the display device to the local monitor output connector (see Rear Panel
Connections on page 3) and power on the display.
3. Power on the source device.
NOTE: EDID information must be available to the source device as it boots up. Before
booting the source device, make sure the RGB 203 Rxi and the local monitor (if
required) are powered on and the rotary dial is set to the correct value.

LCD Display
h LCD display — The LCD displays the horizontal and vertical scanning rates of the input
signal, and indicates the horizontal and vertical centering status and limits.
LCD screen backlight
The LCD lights for 15 seconds at power-up and it remains lit 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 DIP switch 8 (No Backlight) to On (up) (see Rear Panel DIP Switches on
page 8).
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 DIP switch 8 is set to On (up), the LCD lights
for three seconds only (see Rear Panel DIP Switches on page 8).
z 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.
z 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; the second line shows the
vertical rate in Hertz.
Centering indications
While the vertical ({) or horizontal ([) centering (shift) controls are being adjusted, the LCD
displays H-Shift or V-Shift. 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.
Once the centering controls are no longer active, the centering settings are saved, and the
LCD displays the current scan rates.
If DIP switch 1 (DDSP) on the rear panel is set to On (up, see Rear Panel DIP Switches on
page 8) and a centering control is rotated, the LCD displays N/A DDSP On, and the image
does not shift on screen.

with SIS commands (see page 24) or the RGB 201/203/580 Control Software (see
page 23).
RGB 203 Rxi • Operation 16
Contact Closure Remote Control
Troubleshooting
If the Image Does Not Appear or There is No Sound
The rear panel Remote connector also provides a way to select an input to the interface
using a remote contact closure device. Contact closure control uses pins on the Remote
connector that are not used by the RS-232 interface. The contact closure pin assignments
are shown in the table in gure 4.
To select a different input number using a contact closure device, momentarily short the pin
for the desired input number to logic ground (pin 5). To force one of the inputs to be always
selected, leave the short to logic ground in place. The short overrides front panel input
selections.
NOTE: Shorting the contact closure pin to override the front panel selection does not
work if the interface is in auto switch mode with DIP switch 7 on the rear panel
set to On (up).
Turn on the input devices (computer, audio device) and output devices (projector, monitors,
speakers). The image should now appear on the screen and sound should be audible.
1. Ensure that all devices are plugged in.
2. Make sure that each device is receiving power. The front panel LCD of the interface
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. If using the model that has the EDID Minder, make sure the rotary dial and frequency
DIP switch are set to the correct values. If these settings are changed, reboot the source
device.
5. If using the model that has the EDID Minder, make sure the video output can support
the resolution provided by the EDID Minder. If necessary reset the rotary dial and reboot
the source device.
6. For digital display devices (including LCD, DLP and plasma devices), try changing the
setting of DIP switch 1 (DDSP).
7. To test the system setup and output, substitute a video test generator (VTG) for one
of the computer inputs. To use a stand-alone VTG, disconnect the input and output
devices, disconnect the power cord to the interface, replace the video source with a
VTG, and restore AC power to the interface.
8. Call the Extron S3 Sales and Technical Support Hotline if needed (see the phone
numbers listed on the back page of this guide).
RGB 203 Rxi • Operation 17
If the Image is Not Displayed Correctly
1. If the output image looks too green, the sync on green (SOG) DIP switch (switch 2)
may be set to On (up), and the display device may not be configured to handle SOG
signals. Set the switch to Off (down).
2. If the picture bends or flags at the top of the screen, set the serration pulse DIP
switch (switch 3) to Off (down).
3. For a display device that experiences intermittent glitches, try changing the DDSP setting
using DIP switch 1.
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.
6. If using the EDID Minder model, make sure the rotary dial and two position
(frequency) DIP switch are set to the correct values. If these settings are changed,
reboot the source device.
7. If using the EDID Minder model, make sure the video output can support the resolution
provided by the EDID Minder. If necessary reset the rotary dial and reboot the source
device.
8. If the image still does not display correctly, call the Extron S3 Sales and Technical Support
Hotline (see the phone numbers listed on the back page of this guide).
If the Interface Does Not Respond to Controls
1. If you cannot adjust the horizontal ([ knob) or vertical ({ knob) centering, DDSP
may be in use. Ensure that DIP switch 1 (DDSP) on the rear panel is Off (down).
2. If you cannot shift between inputs (input selection switch) or adjust the horizontal
([ knob) or vertical ({ knob) centering from the front panel, but you can operate
the interface via a remote control, the interface may be in front panel security lockout
(executive mode). Toggle executive mode off (see Front Panel Security Lockout on
page 16).
If the Image is Not Correctly Centered
If the picture from a new source computer does not seem correctly centered, the input
position memory presets might require resetting. Reset the input position memories as
follows:
1. Unplug the AC power cord from the interface.
2. Hold the input selection switch up while you plug in the AC power cord to the interface
and wait approximately 5 seconds.
3. Select the appropriate input and adjust the horizontal and vertical centering.
If Auto Switching Does Not Work
Auto switch works for RGBHV and RGBS video inputs only. Auto switch does not work for
RGsB video input.
NOTE: The selection of RGsB video output on rear panel DIP switch 2 has no effect on
auto switching.
RGB 203 Rxi • Operation 18
If the Interface Does Not Record EDID
1. Make sure you have a display device connected to the local output.
2. Make sure the rotary switch is set to 0.
3. Make sure the LED flashes red slowly three times while the EDID information is stored
and returns to a solid green when the recording is completed.
4. Check Record EDID Information on page 12 and Using User-Recorded EDID
Information on page 14.
NOTE: EDID information must be available to the source device as it boots up. If you
make changes to the EDID source by adjusting the rotary dial or the frequency
DIP switch, you must reboot the source device.
If the Source Does Not Output the Correct Rate
NOTE: The resolution provided by the EDID source must be less than or equal to the
resolution of the output device.
1. Make sure you have the correct resolution and frequency selected on the rotary dial and
the DIP switch. After they have been reset, restart the source device.
2. If you are using a user-recorded EDID, make sure the rotary switch is set to 0 and make
sure valid EDID information has been saved to position 0 (see Using User-recorded
EDID Information on page 14).
3. If you are passing through EDID from a display connected to the local monitor output,
make sure the rotary dial is set to position F and make sure the display is properly
connected to the output connection.

Simple Instruction Set (SIS) Control
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 responses 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).
The interface displays the copyright message when it first powers on. Vx.xx is the firmware
version number.
(C) Copyright 2002, Extron Electronics, RGB 203 Rxi, Vx.xx
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:
RECONFIG
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 and Response table in this
chapter).

RGB 203 Rxi • SIS Commands 24
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)
E06 – Invalid input selection
E10 – Invalid command
E13 – Invalid value
(the number is out of range/too large)
Timeout
Pauses of 10 seconds or longer between command ASCII characters result in a timeout. The
command operation is aborted with no other indication.
Using the Command and Response Table
The command/response table is on page 24. Lower case letters are allowed in the command
field only as indicated. Symbols are used throughout the table to represent variables in the
command/response fields. Command and response examples are shown throughout the
table. The ASCII to HEX conversion table, below, is for use with the command/response
table.

Rack Mounting
UL Guidelines for Rack Mounting
The following Underwriters Laboratories (UL) guidelines are relevant to the safe installation
of these products in a rack:
1. Elevated operating ambient temperature — If the unit is installed in a closed or
multi-unit rack assembly, the operating ambient temperature of the rack environment
may be greater than room ambient temperature. Therefore, install the equipment in
an environment compatible with the maximum ambient temperature (Tma: +113 °F,
+45 °C) specified by Extron.
2. Reduced air ow — Install the equipment in the rack so that the equipment gets
adequate air flow for safe operation.
3. Mechanical loading — Mount the equipment in the rack so that uneven mechanical
loading does not create a hazardous condition.
4. Circuit overloading — Connect the equipment to the supply circuit and consider the
effect that circuit overloading might have on overcurrent protection and supply wiring.
Give appropriate consideration to the equipment nameplate ratings when addressing
this concern.
5. Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted
equipment. Pay particular attention to supply connections other than direct connections
to the branch circuit (such as the use of power strips).
Rack Mounting Procedure
The unit can be mounted on either of these optional rack systems:
RSU 129 — 9.5 inch deep 1U universal rack shelf kit (part number 60-190-01)
RSB 129 — 9.5 inch deep 1U basic rack shelf (part number 60-604-02)
To mount the interface on a rack shelf, follow the instructions provided with the shelf
accessories.
