Connecting the RGB 320 Switching Interface

The RGB 320 has six inputs and two outputs, plus connections for RS-232 controls. Figure 2-1 shows an example of the types of equipment that may be part of the interface system.

Each RGB 320 input has five BNC connectors to allow for RGsB, RGBS or RGBHV input. There are also connectors for stereo audio. Although different devices can be used as inputs to the RGB 320, it was designed to be the center of a switching interface system, using buffer devices mounted in a wall, a table or a podium. Extron makes three types of buffer units that provide remote input to the RGB 320. In addition, the RGB 320 is a switcher, allowing one of six inputs to be displayed through a projector or monitor.

The two buffered outputs are identical, with six BNC connectors and 2-channel stereo audio. For example, one output may be used for the main display device (a projector or data monitor), while the other may go to a rack or podium mounted monitor. Switching and controls affect both output devices the same.

Figure 2-1. The RGB 320 as a Computer Video Switching Interface to a Line-quadrupling System

The example in Figure 2-1 includes a System 4LQex as the device that feeds the projector, with the RGB 320 as its fourth input. This allows for six remote computer video inputs, through the RGB 322, 324, 326 and 340 buffers, and three System 4 inputs for other video input signals to be line-quadrupled.

The main focus of the procedures described here will be for using these input buffers: RGB 322, RGB 324, RGB 326 and RGB 340. A User’s Manual

(P/N 68-338-01), which gives details on installation and operation of the buffers, is also shipped with each buffer.
