Chapter 1 • Introduction to RGB 300 The Extron RGB 300 is a digitally controlled Universal Analog/ ECL Computer-Video Interface. It can connect most any computer to a video presentation device, such as a large screen projector or data monitor. The RGB 300’s built-in intelligence automatically selects sync settings and other parameters for quick, easy setup.
Chapter 1 • Introduction to RGB 300 2. The user may write software to control the RGB 300 from a PC, or other system. See the Programmer’s Guide is in Appendix A. Chapter 1 • Introduction to RGB 300 Front Panel Controls The Front Panel LCD display is normally in a 3-menu default cycle, displaying important video input information: The RS-232 protocol is fixed at 9600 baud, no parity, 8 data bits and 1 stop bit.

Chapter 3 • RGB 300 Front Panel Procedures ____ This chapter give procedures for setting up the RGB 300. For the over-all picture, as well as details about each menu, see Chapter 4. Auto-Select Function The Auto-Select function takes place on power up, as well as any time the input scan rate changes. Auto-Select searches all the saved memory blocks for a scan rate match. When a match is found, all the settings from that memory block are automatically loaded.
Chapter 3 • RGB 300 Front Panel Procedures Adjust Current Settings 1. From the 3-menu display cycle, press Menu to step through, and view the following control menus. Use the cursor keys ( ) to change the setting. These are only examples: 2. Level Control - Use Cursor keys to change, and Menu to accept and go on.

Chapter 4 • RGB 300 LCD Menu Descriptions RGB 300 Menu Sequence Chapter 3 gives procedures for setting up specific functions. This chapter is intended to provide detailed description of all menus, not necessarily in a sequence. Use the menu flowchart to locate the menu you want described. Actual information displayed in the LCD menus will depend on settings. The individual menus are described on the following pages.
Chapter 4 • RGB 300 LCD Menu Descriptions Locking/Unlocking The Front Panel To lock the front panel press and hold the keys at the same time, for about 2 seconds, until the display reads as shown. To unlock the keyboard repeat the procedure until the display reads as shown to the left. Note: Once the keyboard is locked it will remain locked even if the power is removed.
Chapter 4 • RGB 300 LCD Menu Descriptions Sync Options There are three possible menu paths entered through the Sync On xxxx menu. Each path goes through five menus related to sync option switches. The Select key is used to step through the menus, while the cursor keys are used to toggle the settings. Sync Output Menu The first sync menu displayed allows the user to change the sync output. This menu shows the sync defaults to the green video channel.

Chapter 5 • Using RGB 300 Windows® Software The software provided by Extron runs under Windows® for controlling the RGB 300 through the RS-232 port. This software uses a control panel in a Window, with easy-tooperate controls. This panel may be used to do any of the Front Panel operations, as well as load, change, store and restore video format information in the memory blocks. See picture on next page.
Chapter 5 • Using RGB 300 Windows® Software Chapter 5 • Using RGB 300 Windows® Software ____ Using the following features to save and restore scan rate configurations to/from disk allows for a virtually unlimited number of configurations to be saved, and loaded when needed. Fade In/Fade Out When this button says "Fade Out" clicking it makes the video display fade to black, and the button changes to say "Fade In". Clicking the button again fades the picture back and changes the button name.

Communication Format Appendix A • Programmer's Guide This detailed programming guide is for the user who plans to write his/her own software for controlling the RGB 300. It is not related to do with the Windows software described in Chapter 4. Knowledge of hexadecimal and binary numbers is recommended when writing programs for the RGB 300. Number conversion is discussed on A-5.
Appendix A • Programmer's Guide Checksum Disabling the Checksum feature Appendix A • Programmer's Guide Communication Protocol Host Initiated Communication (CMDn) The Checksum feature can be disabled by using the following procedure. Commands originating with the Host, can either send information to the RGB 300, or request information from the RGB 300. After receiving a command, the RGB 300 executes it and sends a Response back to the Host.

The command breakdown is explained on page A-1 and numbering conversion is explained on A-5. If it is necessary to convert to decimal, review to those sections. CMD0 (30) - Report Scan Rate The Host asks RGB 300 to report the current scan rate frequencies. The RGB 300 responds with the frequencies detected from the video input.
Appendix A • Programmer's Guide Using Commands - CMD2 CMD2 (32) Report RGB Code (video input detector) The Host asks the RGB 300 which video signals are detected on the R, G, and B inputs. The RGB 300 sends one data byte, with a bit assigned to each color. Bit #s in byte: Appendix A • Programmer's Guide Using Commands - CMD3,4 CMD3 (33) - Report Programmed Sync Code The Host asks the RGB 300 to report which sync code has been set. The RGB 300 responds with a data byte containing sync information.
Appendix A • Programmer's Guide Using Commands - CMD5,6 To convert this use the where data1 = 141: 1. disregard bit 7 (or subtract 128 from data1). (141 - 128 = 13) 2. divide step 1 result by ten. (13/10 1.3, this is version) CMD5 (35) - Report Actual Sync Code The Host asks the RGB 300 for the sync code being used. (This is the programmed code modified by the sync autoselect circuit.) The RGB 300 sends a data byte containing the sync code.
Appendix A • Programmer's Guide Using Commands CMD9,10 CMD9 (39) - Set Horizontal Shift The Host tells the RGB 300 to set the horizontal shift. This command is like CMD8, but the data is going the other way. The command includes three data bytes for the horizontal shift information. Using Commands - CMD11,12,13 CMD11 (3B) - Set Vertical Shift The Host tells the RGB 300 to set the vertical shift information. This is like CMD10, but the data is going the other direction.
Appendix A • Programmer's Guide Using Commands - CMD14,15,16 Response: CMD13, ERC, CKS1, CKS2, EOT CMD14 (3E) - Report Menu Language The Host asks the RGB 300 which language is currently being used to display the menus. The RGB 300 responds with one data byte with the language mode encoded.
Appendix A • Programmer's Guide Using Commands - CMD20,21 Response: CMD19, ERC, CKS1, CKS2, EOT CMD20 (44) - Report Keyboard Lock Status The Host asks the RGB 300 if the keyboard is locked or unlocked. The RGB 300 responds with a data byte containing this information.
Using Commands - CMD23,24 Appendix A • Programmer's Guide CMD23 (47) - Save Current In Memory Block The Host tells the RGB 300 to save the current settings in a specific memory block, and give it a name. This command includes seven data bytes to provide the memory block number, and the ascii characters that make up the name. Note: Refer to an ASCII table for the necessary codes and set bit7 on.
