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.

Introduction, cont’d
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 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:
1
Turn all of the equipment (computers, remote controls,
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 configuration
require opening the interface’s case and should be done
before the interface is mounted.
2
10
For the RGB 203 Rxi VTG, set up and test the VTG. See
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).
Slide cover back slightly,
then lift straight up.
If you want the interface to always output positive sync or
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
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
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
appropriate brackets and furniture or rack mount the
interface. See Mounting the Interface in this chapter.

The interface is factory configured for the output sync to follow
the input sync. To force positive or negative sync, reconfigure
the jumper as follows:
1.
Locate jumper blocks J6, J7, and J20 on the printed circuit
board.
2.
For sync follow (output sync polarity identical to the
input sync), ensure that the jumper is removed from
jumper block J20.
3.
For positive or negative sync, ensure that a jumper is
installed in jumper block J20 and configure J6 and J7 as
follows:
a.
Vertical sync —
For positive sync, ensure that a jumper is installed in
jumper block J6.
For negative sync, ensure that the jumper is removed
from jumper block J6.
b.
Horizontal sync —
The built-in mini VTG is factory configured to output the
selected test pattern for 5 minutes. After the VTG times out, the
screen dims, but is still visible. The output remains dim until
you operate any of the front panel controls, resetting the timer
and outputting the VTG test pattern at full intensity.
Disable the VTG timer, causing the mini VTG to continuously
output the selected test pattern at full intensity until you turn
off the VTG portion of the interface as follows:
1.
Locate DIP switch J27 on the printed circuit board.
2.
Remove the jumper from J27.
Mounting the Interface

If the interface receives a typical (0.7 volts p-p) analog
computer video input, the output is as follows:
•
At the minimum level setting (the counterclockwise limit of
this control), the interface outputs 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 range (indicated by
the red line on the interface, the shaded area on the
illustration to the left) to output unity level video.
•
At the maximum level setting (the clockwise limit of this
control), the interface outputs video at 1.45 volts p-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

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
RGB 203 Rxi, RGB 203 Rxi VTG • Installation and Operation
DDSP disables the interface’s vertical and horizontal
centering controls. If DIP switch 1 (DDSP) is set to On
and either centering control is rotated, the LCD displays
N/A DDSP ON.
To use the display’s centering controls rather than the
interface’s controls, set the DDSP DIP switch to On.
Executive mode (see Executive mode in this chapter)
disables the interface’s vertical and horizontal centering
controls. If executive mode is on and either centering
control is rotated, the LCD displays EXEC MODE ON.
The centering controls have no mechanical limits to
rotation. When the minimum or maximum limit of the
control is reached, LCD indicates the horizontal or
vertical shift limit has been reached and the picture stops
moving on the screen.
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.

Operate the VTG as follows:
1.
Set the front panel 203/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.
203 (interface)/VTG selection switch — Use this switch to
select the output signal’s source:

Simple Instruction Set 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).
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 203 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 203 Rxi VTG is set to VTG mode)
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/response table
The command/response table is on page 3-5. 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, on the next page, is for use with the command/response
table.
(C) Copyright 2002, Extron Electronics, RGB 203 Rxi, Vx.xx
The interface displays the copyright message when it first
powers on. Vx.xx is the firmware version number.
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

The control program window (Figure 3-2) appears and
displays current settings.
Control Software for Windows
The included RGB 201/203/580 Control Program, graphical
control software for Windows, offers another way to control the
interface. The control software is compatible with Windows 3.1,
3.11, 95/98, and above.
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:\RGB201 directory, and it
places two icons (RGB 201 Control Pgm and RGB 201 Help) into
a group or folder named “Extron Electronics”.
Using the software
To run the control program, follow these steps:
Figure 3-2 — RGB 203 Control program window
Using the help system
For information about program features, you can access the help
program in any of the following ways:
•
From the Extron Electronics program group, double-click
on the RGB 201 Help icon.
•
From within the Windows-based RGB 201/203/580
Control Program, click on the Help entry on the task bar.
•
From within the Windows-based switcher control
program, press the F1 key.
Contact Closure Remote Control
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 on page 3-2.
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.
