Installation and Operation Overview

To install and set up an RGB 324, RGB 326, or RGB 340 buffer, follow these steps:

1Determine the installation location.

2Prepare the site for installation. Use the template supplied in the appendix to mark the site, then cut out the wallboard or wood.

3Set the jumpers. The jumpers will be inaccessible after installation.

4Connect cables to the buffer for power and for audio and video output. These cables will be inaccessible after installation.

5Set the front panel High Z/75 Ohm video termination toggle switch.

6Temporarily connect input cables and apply power to the buffer, the RGB 320, and the input and output devices. See the “Pre-installation testing/troubleshooting” section in this manual.

7Temporarily disconnect power. Remove cables as needed, and mount the buffer to the wall or furniture.

8Reconnect cables and power, and adjust centering and levels as needed.

Installation and Operation Instructions

Preparing the site, installing the wall box (RGB 324, RGB 326)

When selecting an installation site, choose a location that will allow cable runs without interference, preferably next to a

2” x 4” wall stud or a structural element of the furniture. Allow enough depth for both the wall box and the cables. You may need to install the cables into the wall, furniture, or conduits before installing the buffer.

The RGB 324 and RGB 326 are typically installed in a 2-gang, 3.5-inch deep, metal wall box (provided by Extron). A different wall box, a plastic box, or no box at all can be used, as long as the installation conforms to electrical codes and to the interface’s size requirements. Dimensional drawings and actual-size cut-out templates are provided in appendix B.

1.Cut out the center portion of the cut-out template, which is provided in appendix B.

2.Place the template (or the wall box) against the installation surface, and mark the guidelines for the opening on the wall or furniture.

3.Cut out the material from the marked area with a jigsaw or small hand saw.

4.Check the opening size by inserting the wall box (if used) or the interface (if no wall box is used) into the opening. The box and/or interface should fit easily into the open- ing. Enlarge or smooth the edges of the opening if needed.

5.Attach the wall box to the wall stud or furniture with nails or screws, leaving the front edge flush with the outer wall or furniture surface, as shown in the following illustration.

Attaching the wall box to a wall stud

If attaching the wall box to wood, use four #8 or #10 screws or 10-penny nails. A minimum of 1/2 inch (1.3 cm) of screw threads must penetrate the wood.

If attaching the wall box to metal studs or furniture, use four #8 or #10 self-tapping sheet metal screws or machine bolts with matching nuts.

6.Feed cables through the wall box punch-out holes for connection to the buffer, and secure them with cable clamps to provide strain relief.

7.Exposed cable shields (braids or foil) are potential sources of short circuits. Trim back and/or insulate shields with heat shrink.
