This guide provides quick start instructions for an experienced installer to set up and operate Extron® RGB 472xi/474xi/478xi/478 Mxi wall-mountable analog computer-video interfaces.

Installation

Step 1 — Preparing the mounting surface

a. Place the wall box against the installation surface, and mark the opening guidelines.

b. Cut out the material from the marked area. c. Secure the wall box with 10-penny nails or #8 or #10 screws, leaving the front edge ﬂush with the surface. d. Run all required cables (see step 3) and secure them with cable clamps.

Step 2 — Power

Turn off or disconnect all equipment power sources.

Step 3 — Rear panel connections and settings

Cable and test the interface before installing it in the wall. Connectors and some controls will be inaccessible once

the interface is installed.

Use a level to mark the opening.

In order to ﬁt in the junction box, do not install a boot on TP cables and RJ-45 connectors.

Items g, h, i, and j are present on the RGB 474xi only. On the RGB 478xi,

this space hold AAPs. On the RGB 478 Mxi, this space hold MAAPs.

DIP switches — This bank of DIP switches conﬁgures

the interface as shown at right. the default position for all switches is off (down).

Gain switch — Compensates long cable runs. Set the

switch to one of three positions as follows:

Normal (inside position) — Unity (no signal boost) Medium (middle position) — Mid-level peaking and

gain Maximum (outside position) — Maximum peaking and gain, Use this setting for longer cable runs.

125 feet (38.1 m), and gain is set to medium or maximum, the image may be overcompensated. If the image edges seem to exceed their boundaries or thin lines and sharp edges look fuzzy, reduce the gain setting.

Power connector — Connect the included 12 V power supply (or any 9 V to 24 V power supply) to the interface as shown at right.

Insert the wires into the connector and tighten the screws. Polarity is not important.

This product is intended to be supplied by a Listed Power Unit marked “Class 2” or “LPS”, rated 9 VDC to 24 VDC, 0.2 A minimum.

Always use a power supply supplied by or speciﬁed by Extron. Use of an unauthorized power supply voids all regulatory compliance certiﬁcation and may cause damage to the supply and the end product. Unless otherwise stated, the AC/DC adapters are not suitable for use in air handling spaces or in wall cavities. The installation must always be in accordance with the applicable provisions of National Electrical Code ANSI/NFPA 70, article 75 and the Canadian Electrical Code part 1, section 16. The power supply shall not be permanently ﬁxed to a building structure or similar structure.

Contact closure connector — Connect a contact closure device for remote selection of the input. Insert the wires into the connector

and tighten the screws. For contact closure control, short the pin for the desired input to the ground pin to select that device.

For contact closure control, auto-switch mode must be off. See DIP switch 7 (item c, above).
