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.
