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.

Chapter 1 • Introduction to the RGB 320 Switching Interface System

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:

1-1

RGB 320 Switching Interface System • User’s Manual • Extron

Chapter 1 • Introduction to the RGB 320 Switching Interface System

• horizontal shift (from RGB 322, RGB 324 & RGB 340)

• vertical shift (from RGB 324 & RGB 340)

• video level (from RGB 324 & RGB 340)

• audio level (from RGB 324 & RGB 340)

The RGB 320 saves these adjustments in a memory associated with each input.

The RGB 320 has 15 memory blocks for each of the six inputs. The memory blocks store the picture controls needed for an application or installation. When an input buffer is selected, with a computer connected, the RGB 320 searches for a match for that scan rate and automatically recalls the appropriate input settings for that device. This eliminates having to recalibrate the settings each time a specific computer is selected. Ten of the most popular computer scan rates are permanently programmed into the RGB 320’s memory so programming may not be necessary.

Figure 1-2. The RGB 322 and RGB 324 Can Be Installed in Walls

The RGB 320 has features that help to maintain the original signal integrity and enhance overall system performance. A video level control is provided to compensate for weak signal source or signal loss due to cables or other system components. For example, if the signal from input #1 is weak, this control can boost it; if the signal from input #3 is strong, it can be attenuated. Each setting is stored for that input.

The RGB 320 also provides LCD sync processing that ensures a stable image for LCD and DLP presentation devices.

Controlling the RGB 320 Interface

The RGB 320 can be controlled from front panel control buttons, from the RGB 322, RGB 324 and RGB 340 buffers with “virtual interfacing” or with Extron’s Windows® Control Program software. An RS-232 serial port allows control by a third party control system. Extron’s software allows control of the RGB 320 from a remote PC with a graphic interface.

The six inputs to the RGB 320 can originate from remote input buffers or from a (local) device in the rack, such as another switcher, a line doubler, a dedicated audio system or a computer interface. The RGB 322, 324, 326 or 340 input buffers may be located in various places around a room. The RGB 320 switches the signals to a display device, a system switcher or a line doubler, etc.

Chapter 1 • Introduction to the RGB 320 Switching Interface System

RGB 322, RGB 324, RGB 326 and RGB 340 Input Buffers

The RGB 322, 324 and 326 are each mounted on a two-gang wall plate that can be installed in a wall, conference table, podium, etc., while the RGB 340 mounts under a table or shelf. Each buffer has a 9-pin input connector compatible with computers that output analog RGsB, RsGsBs, RGBS and RGBHV.

________ These buffer units have their own User’s Manual

(68-338-01).

A “Show Me” button on the RGB 322, RGB 324 and RGB 340 buffer units allows the user to select their buffer as the active source and present their output onto the main display via the RGB 320. This is called “virtual interfacing” control of the RGB 320. Virtual interfacing also allows interface adjustments to be made from certain buffer models. Thus, users may interact with the main display directly from their buffer locations.

All buffers are available in gray, and the 2-gang wall plates are also available in black or white face plates, so they can blend into walls, podiums, tables, etc. Control can be via the RGB 320 front panel buttons, RS-232 control and Extron’s control program for Windows®.

• Virtual interfacing– Allows you to make various video and audio adjustments that are passed to the RGB 320, which then executes the adjustments and stores them in memory.

• Show Me button– You can remotely select your own buffer to become the active input source and, via the RGB 320, display their information on the presentation devices.

• Horizontal Shift (centering)– This adjusts the horizontal position of the image on the video display.

• Remote connection– The buffers provide remote input connection for a permanent A/V installation that requires more than one interface location.

• Universal compatibility– The buffers output analog RGsB, RsGsBs, RGBS and RGBHV video signals, ensuring compatibility with all types of analog computer inputs.

The RGB 324 and RGB 340 have all of the features of the RGB 322 as well as these:

• Show Me button– With the RGB 324 and RGB 340, the Show Me button acts not only as the buffer’s source selector, but also as the primary switch that allows video and audio level adjustments to be made.

• Vertical shift (centering)– This allows vertical movement of the video image for a centered presentation display.

• Video & audio level– The RGB 324 and RGB 340 allow you to make video and audio level adjustments right from the buffer.

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 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.
