Installation and Operation

Installation Overview

To install and set up an RGB 400 Series interface, follow these basic steps:

1Determine the installation location.

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

3Set the DIP (dual in-line package) switches and jumpers. These items will be inaccessible after installation.

4For the RGB 408, attach optional adapter plates, and attach output cables to the back sides of the adapter plates.

5For all models, connect the wires and cables for power, audio output and pass-through signals.

These items will be inaccessible after installation.

6For all models, set the front panel High Z/75 Ohm video termination toggle switch.

7Temporarily connect the input cables. Connect any cables whose signals will be routed through the optional adaptor pass-through plates.

8Connect power cables to the input and output devices. Turn on the input and output devices.

9The image should now display on screen. If it does not display, or if the picture displays incorrectly, double check and make adjustments to cables, DIP switches and jumpers as needed. Refer to the “Pre-installation testing/troubleshooting” section in this chapter.

10Temporarily disconnect the input cables from the front panel of the interface, and disconnect the power from the interface.

11Mount the interface in the wall or furniture.

12Reconnect the computer video and audio input cables to the interface, apply power, and readjust horizontal centering as needed via the front panel control.

Installation and Operation Instructions

Determining installation location

Take cabling and power availability and the location of wall studs into consideration when selecting an installation site. You may need to install the cables in the wall, furniture or conduits before installing the interface. Choose a location that will allow cable runs without interference, preferably next to a 2” x 4” wall stud.

The RGB 400 Series interfaces each consist of a front panel with an attached circuit board. They are typically installed in standard 2-, 3- or 4-gang, 2.5-inch deep electrical wall boxes. A metal wall box (provided by Extron) is preferred, but a plastic box (or no wall box at all) can be used as long as it conforms to local code restrictions and the interface’s size requirements. If a wall box is used, it must be attached to wall studs within the wall.

The drawing below illustrates the typical depth required to accommodate the maximum bend of high resolution (SHR) coaxial and miniature coaxial cables inside a wall box.
