Introduction, cont’d Introduction About the RGB 324, RGB 326, and RGB 340 Interface Buffers The Extron RGB 324, RGB 326, and RGB 340 interface buffers distribute analog computer video and audio signals to the RGB 320 switching interface system. These buffers each offer a 300 MHz (-3dB) video bandwidth. They provide remote input connections to the RGB 320 interface for permanent installations in environments such as conference and training rooms or command and control centers.

Installation and Operation, cont’d Installation Installation and Operation Overview To install and set up an RGB 324, RGB 326, or RGB 340 buffer, follow these steps: 1 Determine the installation location. 2 Prepare the site for installation. Use the template supplied in the appendix to mark the site, then cut out the wallboard or wood. 3 Set the jumpers. The jumpers will be inaccessible after installation. 4 Connect cables to the buffer for power and for audio and video output.
Installation and Operation, cont’d 8. Front and rear panel features Set the rear panel peaking jumpers, and cable and test the buffer before fastening the buffer into the wall box. The jumpers and cables will be inaccessible after installation. See “Rear panel/circuit board features and jumpers” and “Cabling” in this chapter for details.

Strip 7” to 8” (18 cm to 20 cm) of the outer jacket from the end of the cable. 4. Use a pointed tool to separate the braided wire shield surrounding the cable. Pull the ends of the braid away from the cable, twist the braid wires together, and clamp them to the electrical box (if used). See “Connecting shields”, page 2-10.

Installation and Operation, cont’d Pre-installation testing/troubleshooting Before installing a buffer into the wall or furniture, test the system to make sure that the connections and settings are correct. 1. With the power disconnected from the RGB 320, connect the cables between the buffer and the RGB 320 as described in “Preparing and terminating the cable” in this chapter. 2. Apply power to the RGB 320. The power LED on the buffer will light steadily to indicate that the buffer is receiving power.
