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
connected to the Broadcaster, the
switcher or controller sends IR signals to
controlled devices via the IR Emitter, but
not out the Broadcaster’s emitters.
The IR Broadcaster’s own emitter
devices and the responder LED are
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.
