What is a Switching Interface?

Extron’s RGB 320 combines an interface and a switcher with six inputs and two outputs. It was designed as a system solution for installation environments such as conference or training rooms and command/control centers. The six inputs can use RGsB, RsGsBs, RGBS, RGBHV and line level audio. There are two buffered outputs. One, for example, may go to a projector (the main presentation display) and the other to a viewing monitor located near a podium.

Figure 1-1. Example of an RGB 320 System Using Four Possible Buffer Types in a Conference Room

The RGB 320, together with the RGB 322, RGB 324, RGB 326 and RGB 340 input buffers, acts as a switching interface system, with up to six remote (or local) buffer modules as inputs. These buffers can be installed in various convenient places in a room, such as in a wall, or under a podium or a table. They transfer the individual computer-video and audio signals (RGB 322 does not include audio) to the RGB 320, where they are switched to a display device, a system switcher or a line doubler, etc. The RGB 320 can be mounted in a rack with other A/V components.

Figure 1-1 shows an example of a custom A/V installation in a conference room. An RGB 320 is mounted in the rack outside the room. Inside the room, an RGB 324 has been installed in the wall (top right), an RGB 326 in the left wall, and an RGB 322 is mounted in the right wall, next to the document camera. An RGB 340, mounted in the podium, accommodates the presenter’s laptop computer.

The RGB 322 buffer has Horizontal Shift adjustment and Show Me. The RGB 326 has video and audio inputs, a termination switch and an LED that indicates when this buffer is the active input.

Function

While the interface functions are processed within the RGB 320, “virtual interfacing” can be done from the RGB 322, RGB 324 or RGB 340 buffers. The “Show Me” button on these buffers requests that its signal(s) be switched to the RGB 320 output device. It can also initiate communication with the RGB 320 to allow the following adjustments to be made from the panel:
