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.

Installation and Operation Wiring tip-ring-sleeve and tip-sleeve connectors The illustration below shows how to wire a 3.5 mm stereo-style (tipring-sleeve) connector for the IR Broadcaster voltage, signal, and ground wires to connect the System Switcher or MLC to the IR Broadcaster. 1 Unscrew cover. 5 Solder 3 wires. 2 Locate components. Sleeve (Gnd) Tip (+12V) Ring Sleeve Ring (Signal) 6 Bend tabs up over cable insulation. 3 Slide cover and heat shrink Tip over cable.
1/4” (0.6 cm) of insulation from each wire. Do not solder the tips. Insert each wire into the correct position on the captive screw connector, and tighten each screw. See the diagrams below. To pass through an IR signal that includes a carrier signal, connect the signal wire to the pin designated for carrier and signal. If you want the IR Broadcaster to generate the carrier signal, connect the signal wire to the pin designated for signal only.
