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.

Installation Overview
To install and set up an RGB 400 Series interface, follow
these basic steps:
1
Determine the installation location.
2
Prepare the site for installation. Use the supplied
template to mark the rough-in cutout, then cut out
the wallboard or wood.
3
Set the DIP (dual in-line package) switches and
jumpers. These items will be inaccessible after
installation.
4
For the RGB 408, attach optional adapter plates, and
attach output cables to the back sides of the adapter
plates.
5
For all models, connect the wires and cables for
power, audio output and pass-through signals.
These items will be inaccessible after installation.
6
For all models, set the front panel High Z/75 Ohm
video termination toggle switch.
7
Temporarily connect the input cables. Connect any
cables whose signals will be routed through the
optional adaptor pass-through plates.
8
Connect power cables to the input and output
devices. Turn on the input and output devices.
9
The 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.
10
Temporarily disconnect the input cables from the
front panel of the interface, and disconnect the power
from the interface.
11
Mount the interface in the wall or furniture.
12
Reconnect the computer video and audio input
cables to the interface, apply power, and readjust
horizontal centering as needed via the front panel
control.
