Wiring for IR Control
To control devices via infrared (IR) commands from the MLC, connect one or two IR
emitters to the IR/S port (RS models) or the IR port (IR model). The IR and IR/S ports
provide unidirectional IR signal output to control a display, projector, switcher, or other
device such as a DVD player.
You can connect one or two single IR emitters or one dual IR emitter to the IR or IR/S port
to control one or two devices. Because the MLC captive screw plugs have small openings
that accept just one wire per pole, to connect two IR emitters to the MLC insert one
ground wire (black) and one IR signal wire (black with a white stripe) in the MLC 62 IR or
IR/S port. Connect the IR emitters to those wires as shown below.

IR Emitters for the MLC 60 Series
For IR control, there can be a maximum of 50 feet (15 m) between the IR or IR/S port and
the IR emitters.
Example:
Figure 22 shows a single IR emitter connected to the IR/S port of an
MLC 62 RS EU or an MLC 62 RS MK.
