Extron RGB 302/304 Universal Interface • User’s Manual
The Extron RGB 302/304 is a digitally controlled
Universal Analog/ECL Computer-Video Interface. It
can connect most computers to a video presentation
device, such as a large screen projector or data
monitor. The RGB 302/304’s SmartSave™ feature
automatically selects sync settings and other
parameters for a quick and easy setup.
Among the RGB 302/304 features are RGB input/
output connectors, an MBC power jack, audio input/
output connectors, an RS-232 connector, and rear
panel DIP switches.
The RGB 304 is identical in performance and features
as the RGB 302 with the exception being that, unlike
the RGB 302, the RGB 304 has its 9-pin Analog/ECL
input, Audio input, and MBC power jack located on the
front panel of the unit, as shown below. This difference
allows the RGB 304 to be installed in situations where
front panel access to such connectors may be
necessary, such as the mounting of the unit in a rack
mount environment.
RGB 302/304 Features
The RGB 302/304 features allow video output to be
controlled in several ways:
• Automatic sync output detection and setup for quick
installation
• Custom setup and adjustments made from the Front
Panel (shown below)
• RGB 302/304 Windows® software, through an RS-232
interface
• User-written programs through the RS-232 port

SmartSave
™
This unique feature greatly simplifies the video
configuration setup of the RGB 302/304. The
RGB 302/304 comes preset with various video
configurations to match most computer video
requirements. The proper configuration is
automatically selected and implemented for the user.
In addition, the RGB 302/304 will automatically save
any user modifications to the video configuration and
will recall the correct configuration without need for
user intervention.
LCD Menu Driven Controls
The RGB 302/304 does not have front panel “knobs”
or “switches” to control its operation. Instead, the
“controls” are displayed and adjusted using the Front
Panel LCD display and the six front panel buttons.
The Front Panel display can be used in any of four
languages: English, French, Spanish and German.
The display serves two purposes:
1. The RGB 302/304 automatically detects and
displays vital troubleshooting information, such as
the horizontal and vertical scan frequencies.
2. The user can step through and display any of the
controls or features in the interface.
___ Chapter 3 has details on using the Front Panel.
Memory Blocks and Memory Cycling
There are 15 preset memory blocks which store video
format information, such as video, sync and control
settings. Each block is preloaded by Extron and
defines one video configuration (e.g. VESA3, MAC16",
etc.). These preset memory blocks define most video
requirements. In addition, there are 25 user-definable
memory blocks available.
The RGB 302/304 automatically cycles through
(Memory Cycling) the user-defined memory blocks
and loads the video format that most closely matches
the computer’s video output. Should a match not be
found, the 15 preset memory blocks are searched
next (refer to
the section “Memory Cycling Feature”
in
Chapter 2).
Level Control (picture)
This feature is similar to the brightness control on a
data monitor and is used to adjust the intensity of the
video level on the projector/monitor screen by using
the cursor keys. There are 255 levels for this control.
Page 1-2
Chapter 1 • Introduction to the RGB 302/304
Extron RGB 302/304 Universal Interface • User’s Manual
Peaking Control (sharpness)
This control is similar to the sharpness control on a
data monitor. It is also used to compensate for long
cable runs. There are eight Peaking levels which are
selected by using the cursor keys.
Horizontal Shift Control (centering)
This feature shifts the displayed image to the left or
right on the projector/monitor screen by using the
cursor keys. There are 255 positions for this control.
Vertical Shift Control (centering)
This feature shifts the displayed image up or down on
the projector/monitor screen by using the cursor keys.
There are 255 positions for this control.
Automatic Sync Output Detection
The RGB 302/304 automatically detects which cables
are connected and sends either Sync On Green,
Composite Sync or Separate Horizontal and Vertical
sync signals to the correct output cables. This
function can be overridden through menu controls.
Automatic Sync Stripping
The RGB 302/304 automatically strips all incoming
sync from the red, green, and blue channels for clean,
crisp signal processing. Sync may be recombined with
the green channel if necessary.
Keyboard Lockout
The RGB 302/304 features a Keyboard Lockout
function which allows the user to “lock out” the front
panel controls by using “hot keys”. This feature
disables front panel operation after setup.
Auto-switching Power Supply
The RGB 302/304 is equipped with an internal autoswitching power supply that operates from any input
voltage in the 100 to 240 VAC, 50/60 Hz range. No
equipment changes are necessary.
Audio Interface
The RGB 302/304 includes a PC/computer audio (600
ohm) to line-level audio (balanced) converter. For
computers which have a sound card, the audio
interface will process the audio signal along with the
video (audio follow). The audio output can be
connected to an external stereo system.

Chapter 1 • Introduction to the RGB 302/304
DIP Switch Settings
The RGB 302/304 includes a rear panel DIP switch
bank which will activate Digital Display Sync
Processing, remove/pass serration pulses, and set 75
Ohm/high impedance video input termination.
RS-232 Control Interface for Remote Control
The RGB 302/304 has a built-in RS-232 interface to
allow the unit to be controlled remotely in either of two
ways:
1. Use the Windows® RGB 302/304 Control Panel
software provided by Extron (see next section).
2. The user may write software to control the RGB 302/
304 from a PC or control system. See the
Programmer’s Guide in Appendix A.
The RS-232 protocol is fixed at 9600 baud, no parity, 8
data bits and 1 stop bit.
Benefits of Windows® RGB 302/304 Software
Using the Windows® software provided with the
RGB 302/304 adds several advantages over Front
Panel operation.
• All of the controls are quick and easy to use with
the on-screen control panel.
• Application setups can be stored as disk files,
therefore, an unlimited number of setups can be
stored and reloaded from the PC’s hard drive or
floppy disk.
Refer to Chapter 4 for details on using this software.
Extron RGB 302/304 Universal Interface • User’s ManualPage 1-5
Front Panel Controls
The Front Panel buttons (as shown below) have many
functions, depending on which menu is accessed at
any particular time. For example, the user can display
and adjust controls to modify the video display. The
specific functions for these buttons are described
below.
The LCD panel cycles through 3 default menus when
the RGB 302/304 is first powered on. Refer to Chapter
3 for instructions on using the RGB 302/304 menus.
___ There is a built-in time-out function which will return to
the default menu cycle if no buttons are pressed for
approximately 8 seconds. By default, any changes
which were made will be automatically saved upon the
time-out.
Menu button
The Menu button is used to select and step through
the four different menu classes (to be explained in
Chapter 3).
Next button
The Next button is used to advance to the next
submenu of a menu class or to return to the beginning
of the menu class (see the menu flowchart on page 3-1).
Cursor buttons
The cursor buttons are typically used to step through
the menu options before making a choice. These
options could be alpha characters or numeric settings.
The user may also want to change the value of the
current setting (i.e., increase or decrease level, shift,
peaking, etc.). These buttons also serve as
convenient “hot keys” to various functions.
LCD Display
Besides displaying the menus, the LCD display
provides some helpful information, such as which
buttons to use when making choices.
