Extron RGB 302/304 Universal Interface • User’s Manual
The Extron RGB 302/304 is a digitally controlled
UniversalAnalog/ECLComputer-VideoInterface.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.
AmongtheRGB302/304features are RGB input/
outputconnectors,an MBC power jack, audio input/
outputconnectors,an RS-232 connector, and rear
panel DIP switches.
TheRGB304isidentical 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,Audioinput,andMBCpowerjacklocatedonthe
frontpanel 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
mountenvironment.
RGB302/304 Features
The RGB 302/304 features allow video output to be
controlled in several ways:
• Automaticsync output detection and setup for quick
installation
• CustomsetupandadjustmentsmadefromtheFront
Panel(shownbelow)
• RGB 302/304 Windows® software, through an RS-232
interface
• User-writtenprogramsthroughtheRS-232port

Inaddition,theRGB302/304will automaticallysave
anyusermodificationstothe videoconfigurationand

LCD Menu Driven Controls
The RGB 302/304 does not have front panel “knobs”
or “switches” to control its operation. Instead, the
“controls”aredisplayedand adjusted using theFront
Panel LCD display and the six front panel buttons.
The Front Panel display can be used in any of four
languages:English,French,SpanishandGerman.
The display serves two purposes:
1. The RGB 302/304 automatically detects and
displaysvitaltroubleshootinginformation,suchas
thehorizontalandverticalscanfrequencies.
2. The user can step through and display any of the
controlsorfeaturesin the interface.
___ Chapter 3has detailsonusingtheFrontPanel.
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
definesonevideoconfiguration(e.g.VESA3,MAC16",
etc.). These preset memory blocks define most video
requirements.Inaddition,thereare25user-definable
memoryblocksavailable.
The RGB 302/304 automatically cycles through
(MemoryCycling)the user-definedmemoryblocks
and loads the video format that most closely matches
thecomputer’svideooutput.Should a match notbe
found, the 15 preset memory blocks are searched
next (refer to
the section “Memory Cycling Feature”
in
Chapter2).
Level Control (picture)
This feature is similar to the brightness control on a
datamonitor and is used toadjust the intensity of the
videolevelontheprojector/monitorscreenbyusing
the cursor keys. There are 255 levels for this control.

Peaking Control (sharpness)
This control is similar to the sharpness control on a
datamonitor. 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)
Thisfeatureshifts the displayed image to the leftor
rightontheprojector/monitorscreenbyusingthe
cursor keys. There are 255 positions for this control.
Vertical Shift Control (centering)
Thisfeature shifts the displayed imageup or down on
the projector/monitor screen by using the cursor keys.
Thereare 255 positions for thiscontrol.
Automatic Sync Output Detection
The RGB 302/304 automatically detects which cables
are connected and sends either Sync On Green,
CompositeSyncorSeparateHorizontalandVertical
sync signals to the correct output cables. This
functioncan beoverriddenthroughmenucontrols.
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
disablesfrontpaneloperationaftersetup.
Auto-switching Power Supply
The RGB 302/304 is equipped with an internal auto-
switchingpower supply that operates fromany input
voltage in the 100 to 240 VAC, 50/60 Hz range. No
equipmentchangesare necessary.
Audio InterfaceThe RGB 302/304 includes a PC/computer audio (600
ohm)toline-levelaudio(balanced)converter.For
computers which have a sound card, the audio
interfacewillprocesstheaudiosignal along with the
video(audio follow).Theaudiooutputcanbe
connected to an external stereo system.

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/highimpedancevideoinputtermination.
RS-232 Control Interface for Remote Control
The RGB 302/304 has a built-in RS-232 interface to
allowtheunittobecontrolledremotelyineitheroftwo
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 inAppendix 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
UsingtheWindows® software provided with the
RGB 302/304 adds several advantages over Front
Paneloperation.
• All of the controls are quick and easy to use with
theon-screencontrolpanel.
• Application setups can be stored as disk files,
therefore,anunlimited numberofsetupscanbe
stored and reloaded from the PC’s hard drive or
floppydisk.
Refer to Chapter 4 for details on using this software.
