Chapter 2 • Installing the RGB 320 Switching Interface Components

Choosing Cables for Remote Inputs

With the RGB 320 as the center of a computer video interface system, the input connectors have specific functions, and the connectors must not be misused. The ideal installation will use the RGB 322, RGB 324, RGB 326 or RGB 340 as inputs through an installation (or composite) cable. Most of the examples used in this manual will make this assumption. The User’s Manual for the RGB 322,

RGB 324, RGB 326, and RGB 340 gives detailed instructions for installing those devices. (P/N 68-338-01)

_________ Regardless of which cables are used, their connectors must be wired the same

way on both ends. Any crossing of lines could damage the electronic circuits in the buffer unit or in the RGB 320.

Figure 2-8 shows the wiring for the audio, communications and power connector for the buffer. Note that the wire and contact assignments must match those on the RGB 320 end of the cable shown in Figures 2-9a and 2-9b.

Figure 2-8. One Installation Cable Can Be Used for Each Input and Each Output

Composite Cables

Composite cables, such as Extron’s Installation Cable, make installation easier, because one jacketed cable can be dedicated to one input or to one output.

_______ Installation Cable includes a combination of several types of cables that are

enclosed in one jacket. The combination can carry video, audio, power, communications, etc. If you will be making cables, follow the guidelines in Appendix A of the RGB 322, 324,326 and 340 User’s Guide.
