Connecting an IR Broadcaster, IR Emitter, and a system switcher
Using a signal with a carrier signal
For most applications, a signal that already has a carrier frequency may
be used with the IR Broadcaster. Use pin C from the System 5/5cr/5cr
Plus or System 7SC connector, or pin A on the MLC (see diagrams on
page 7), and use the IR Broadcaster’s default DIP switch settings (switch
9 open) to allow the carrier signal to pass through and be broadcast.
This leaves the signal/no carrier pin available for a projector that uses a
wired remote control. The IR Emitter may not be used in this case.
Using a signal without a carrier signal
If you choose to have the IR Broadcaster generate the carrier signal, use
pin A from the System 5/5cr/5cr Plus or System 7SC connector, or pin C
on the MLC (see page 5). You may use an IR Emitter in this case.
If you use an IR Emitter, connect the white lined signal wire to the tip of
the 2.5 mm plug (provided), as shown in the diagram above. Connect
the solid black ground wire to the sleeve.
1.
Open the IR Broadcaster’s case: remove and save the two small
screws from the underside of the enclosure, and lift the top of the
enclosure straight up.

Inside the Broadcaster, set DIP switch

#9 to the closed position (up). This
forces the Broadcaster to generate a
carrier signal.
3.
Set the other DIP switches to deter-
mine the carrier frequency. Page 3
features a table of all the possible
carrier signal output frequencies that
can be selected by setting the DIP
switches. Choose a frequency from
the table that is closest to that
required by the projector (or other IR-
controlled device).

Making the Cable
Extron provides the 3.5 mm connectors with the IR Broadcaster,
however a cable will have to be made to fit your installation
requirements. Use the following information to make the cable.

Because there will be +12 volts on the tip (from the switcher
or the MLC) it is best to plug the cable to the IR Broadcaster
first, and then into the switcher’s or MLC’s panel.
CAUTION
If the projector has round jack marked “Wired Remote”, this may
be wired to pin A. Check the documentation that came with the
projector to be sure of this function.
If using the standard IR Emitter with the IR Broadcaster, a similar
procedure is required to put a 2.5 mm, round, tip-sleeve connector on
the Emitter’s cable. See the illustration on page two for IR Emitter
wiring instructions. The Broadcaster’s internal DIP switches must also
be set to select the outgoing carrier frequency.
A 12VDC, 500 mA output is provided on the Comm port of the
System 5/System 5cr/System 5cr Plus, the IR Comm port of the
System 7SC, and the Display/Source Control IR port of the MLC.
For the end of the cable that goes to the switcher or MLC, connect the
wires to the 3.5 mm, 5-pole captive screw connector. Strip no more than

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.
