Introduction

About the IRL 20

The Extron IRL 20 is a hardwired infrared (IR) signal receiver
for use with Extron IR remote controls and an Extron
MediaLink™ Controller (MLC), MediaLink Switcher, System 5 IP
Switcher, or AVT 100. The IRL 20 receives a signal via its front
panel from an Extron IR remote operating at 38 kHz. It can also
receive IR input via an optional Extron IR Sensor, which is
smaller and less visible than the IRL 20. It outputs the
modulated IR signal via an IR Emitter or the IR Link or CM/IR/
SCP port of a device mentioned above, allowing that device to
be mounted out of sight in a rack or furniture.

Features

Compactness and flexibility — The IRL 20’s small enclosure

can be secured to any surface without having to cut any
holes in furniture or walls. This allows for a wide range
of mounting locations.

IRL 20 Front

(behind the panel) — The sensors that
receive incoming IR signals are behind the
red, plastic, front panel lens near the middle;
toward the left is a green LED that blinks
when an IR signal is received by the IRL 20.
The angles (+/- 40°) and maximum distance

40 40

(up to 30') recommended for best reception
of incoming signals are shown in the
illustration at right.

Communications connector — Use this
10-pole connector to connect the IRL 20 to
other Extron devices. Both halves of the
connector function the same way (either can
be used as an input or an output), so they
are interchangeable.

Extron
IR Remote

Connectors are included with the IRL 20, but the cable
must be purchased separately. See the illustration on the
next page for reference, and see appendix A for cable part
numbers and conductor gauges.

Install a 3.5 mm, 5-pole captive screw connector on one end of
an Extron Comm-Link cable, and plug it into the left or the right
half of this connector. Wire both ends of the cable identically
(ground pin to ground pin, modulated IR to modulated IR, etc.).
Plug the other end of the cable into the appropriate connector
on an Extron MediaLink Controller (MLC), MediaLink Switcher,
System 5 IP Switcher, or AVT 100.

max.

See the illustration at right for
pin assignments:

Other accessories such as an
Extron control module (IRCMs,
ACMs, RCMs) or an SCP
control pad can be connected to
the other 5 poles of
this captive screw
connector.

The Extron switchers and the AVT 100 devices provide 12 VDC
on pin B and a ground on pin A, so there is no need for an
additional power supply.

If the IRL 20 is used with an MLC 104 Series or
MLC 226 Series controller, do not power the IRL 20 from
the MLC: connect an external 12 VDC power supply
(such as Extron part #70-055-01) to those pins.

Connect a maximum of one (1) IRL 20 to a device. Do
not connect more than one IRL 20 or IR Link (either in
parallel or in series) to a switcher, MediaLink Controller,
or AVT.

device that is even less visible than the IRL 20, you can cable an
Extron IR Sensor (part #70-223-01) to this port, hide the IRL 20
within furniture, and place the IR Sensor’s receiver head in the
line of sight of the Extron remote control.

The IR Sensor has a 6' (1.8 m) cord to allow it to
be placed a short distance away from the IRL 20.
The adhesive backing on the back of the receiver
head makes it easy to install without tools (aside
from the small screwdriver needed to fasten the
connector to the end of the wire. See the
diagram at left for pin configurations.

The IR sensor has a 6' (1.8 m) cord, but the maximum
cable length for the IR Sensor is 21' (6.4 m). Do not cut
the IR sensor’s cable or extend it beyond 21 feet.

Typical applications for the IRL 20

Connecting an IRL 20 to a power supply and an IR Emitter

An external, stand-alone power supply is only necessary if the
IRL 20 is not connected to an Extron device that is able to
supply power to it.

1. Attach an external 12 VDC power supply the +12 VDC pin
and the ground pin of a 3.5 mm captive screw connector,
and plug it into one of the IRL 20’s communications
connectors as shown on the next page.

Connect a maximum of one IRL 20. Do not connect
more than one IRL 20 (either in parallel or in series).

2. Attach the black wire of an Extron IR Emitter to pin B
(ground) and the white striped wire to pin D (IR signal) of
a 3.5 mm captive screw connector, and plug it into the
IRL 20’s remaining communications connector, as shown
below. Two or three emitters can be wired to the same
connector, if needed.

You can use one 5-pole connector to connect both the
power input and the IR Emitter (IR output). It is not
necessary to use two connectors.

3. Place the head of the IR Emitter near or in front of the IR
pickup device of the IR-controllable Extron product.
