Introduction

The IR Broadcaster (part #60-272-02)

The Extron Infrared Broadcaster transmits IR signals that have been “learned” by an Extron system switcher or Extron MediaLink Controller (MLC) and that are associated with the front panel functions. This allows other IR controlled devices in the room to receive the signal put out by the Broadcaster. Refer to the appropriate switcher’s or controller’s user’s manual for IR learning procedures.

Pressing buttons on the system switcher’s or controller’s front panel, or on an Extron IR remote control, SCP control pad, or RS-232 host causes the IR Broadcaster to broadcast an IR command that is associated with that button/key. For example, if a command to switch the projector to RGB mode has been “learned” and associated with an input selection button, when that button is selected from a panel, the IR remote control, or from the RS-232 host, that learned command is broadcast.

The switcher or the controller provides power, an IR signal, and a ground connection to the IR Broadcaster through a special three- conductor custom cable. The Broadcaster should be placed so that its signal covers a large area of the room, within the range of the projector or other devices to be controlled by learned commands.

Front and rear panels

The picture below shows the front and rear panels of the IR Broadcast- er. Place the dark red lens side (front) of the Broadcaster toward the room so that the projector (or other device) can receive the IR signals.

For some applications it may be desirable to limit the signal broadcast range. There is a connector on the IR Broadcaster for use with the

standard IR Emitter. If an Emitter is

The IR Broadcaster’s own emitter

devices and the responder LED are Front shown in the illustration. The emitters

are not easily seen through the dark lens, but the responder can be seen when its LED blinks to indicate that an IR signal has been broadcasted.

Installing and Setting Up the IR Broadcaster

The following illustration shows a typically appllication with an IR Broadcaster connected to a switcher, and it also shows how the IR Emitter can be used with the Broadcaster.
