Chapter 1 • Introduction to the RGB 302/304
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

Chapter 1 • Introduction to the RGB 302/304
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.

Chapter 1 • Introduction to the RGB 302/304
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.

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.

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.

Next button
NEXT
The Menu button is used to select and step through the four different menu classes (to be explained in Chapter 3).
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.
