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.
2.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).
