Wiring tip-ring-sleeve and tip-sleeve connectors

The illustration below shows how to wire a 3.5 mm stereo-style (tip- ring-sleeve) connector for the IR Broadcaster voltage, signal, and ground wires to connect the System Switcher or MLC to the IR Broadcaster.

1Unscrew cover.

2 Locate components.			3 Slide cover and heat shrink
Sleeve (Gnd)
Tip (+12V)	Ring	Tip	over cable.

Ring (Signal)		Sleeve	Heat Shrink
4 Strip wires and solder ends, and insert in holes.
	Ring (Signal)
	Tip (+12V)	Sleeve (Gnd)

5 Solder 3 wires.

6 Bend tabs up over cable insulation.

7 Slide heat shrink over exposed wires, and apply heat.

8 Screw cover onto connector.

Wiring the tip-ring-sleeve connector

The contact assignments for the connector are as follows:

Stereo		System 5cr/5cr Plus,	MLC
connector		System 7SC captive	captive screw
part	Function	screw connector pin	connector pin
Tip	+12 volts	E	E

Ring	Signal & carrier	C	A
Sleeve	Ground	B or D	D

CAUTION

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.

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
