Chapter 2 • Installing the RGB 302/304 Audio Output (Left and Right) — There is one audio output using separate connectors for left and right channels. Connect the left and right output jacks to the inputs of an external audio system. The 3-contact outputs can be wired for balanced or unbalanced audio. • For unbalanced audio, use Tip (+) and Sleeve (Gnd) • For balanced audio, use Tip (+) and Ring (-) ____ Observe polarity when making connections to keep left and right channels in phase.
Chapter 2 • Installing the RGB 302/304 Memory Cycling Feature The RGB 302/304 is preset at the factory with fifteen video formats which are stored in memory blocks. These memory blocks contain video formats which will match most computers. There are also 25 additional empty memory blocks which are userdefined. When a video input is connected and the RGB 302/ 304 is powered On, the 25 user-defined memory blocks are scanned (cycled) sequentially for a configuration which matches the computer’s video input.
Chapter 2 • Installing the RGB 302/304 Preset Memory Blocks The Memory Cycling feature supports 25 user-defined memory blocks for storing video configurations and 15 permanently defined memory blocks. The 15 preset memory block video configurations are listed below.

Chapter 3 • Front Panel Menus Using the Menu System The RGB 302/304 control menus are accessed through the Front Panel (refer to Chapter 1, “Using the Front Panel” ). Use the LCD display, together with front panel keys (see below), to view or make changes to the current settings. Observe the monitor or projector screen while making adjustments. The menu flowchart on page 3-1 may be used as a guide while stepping through the menus.
Chapter 3 • Front Panel Menus Default Cycle Menus When the RGB 302/304 is initially powered up, the RGB 302/304 is in a 3-menu default cycle. Several options are also accessible from the default menu cycle: a menu interface language, keyboard lock/ unlock control, ID screen edit menu, and the image controls menus. The image controls menus, one of the four classes of menus, sets image shifting, level and peaking.
Chapter 3 • Front Panel Menus • The third default menu displays what type of Sync Output has been selected and whether the Memory Cycling feature has been turned On or Off. To change any of these menu settings, refer to Sync Output in the “Sync Controls Menus” section and refer to Memory Cycling in the “Option Controls Menus” section of this chapter. Default Cycle Hot Keys You may choose to “hot key” directly out of the default or menu cycle (see note below) by pressing the key.
Chapter 3 • Front Panel Menus Keyboard Lock/Unlock Menu Utilizing the Keyboard Lock/Unlock feature allows the user to lock or unlock the front panel controls for security reasons. While in the default menu cycle, depressing the cursor keys and simultaneously for 2 seconds will either lock or unlock the front panel controls, depending on the original front panel lock/unlock status. ____ Once the keyboard is locked it will remain locked even when power to the RGB 302/304 is removed.
Chapter 3 • Front Panel Menus ____ The following menus require use of the cursor keys to make adjustments or selections. As a matter of convenience (but excluding the use of “hot keys”), or key will have the pressing either the same effect. Similarly, pressing either the key will have the same effect. or Image Controls Menus From the Default Cycle menus, press MENU to advance to the Image Controls menus.
Chapter 3 • Front Panel Menus While observing the video screen, use the cursor keys and to adjust the vertical centering. There are 255 incremental steps for this control. When the adjustment is complete, release the cursor key and press NEXT to go to the Level Control menu, or press MENU to advance to the Sync Controls menus, or allow the time-out to occur to save any changes. Level Control Menu The Level Control menu is similar to the brightness control on a data monitor.
Chapter 3 • Front Panel Menus Sync Controls Menus The Sync Controls menus consists of the Sync Output menus. The Sync Output menu determines how the sync output of the RGB 302/304 is specified. Press NEXT to go to the Sync Output menu, or press MENU to advance to the Option Controls menus, or allow the time-out to occur. Sync Output Menu As shown in the menu flowchart on page 3-1, there are four sets of Sync Output menus, one set for each sync source.
Chapter 3 • Front Panel Menus If sync output is Auto, the possible sync output configurations are: sync on Green (3cable hookup), Composite sync (4-wire hookup), or Separate H & V (5-wire hookup). See the example Default Cycle sync output menus on the left. If the sync output specified above was Separate H & V, the horizontal and vertical polarities may be changed as described in the next sections. Horizontal Polarity Menu The Horz.
Chapter 3 • Front Panel Menus Option Controls Menus Among the menu options for the RGB 302/304 are the LCD Backlite, Memory Cycling, and System Reset. Press NEXT to go to the Backlite menu, or press MENU to advance to the Exit Menu, or allow the time-out to occur.
