Precautions Safety Instructions • English This symbol is intended to alert the user of important operating and maintenance (servicing) instructions in the literature provided with the equipment. This symbol is intended to alert the user of the presence of uninsulated dangerous voltage within the product's enclosure that may present a risk of electric shock. Caution Read Instructions • Read and understand all safety and operating instructions before using the equipment.
Quick Start Guide — IRL 20 Step 1 Turn the equipment off and disconnect the equipment from the power source. Step 2 Cut a length (150'/45 m or less) of Extron Comm-Link cable to go between the MediaLink Controller (MLC), MediaLink Switcher, System 5 IP Switcher, or AVT 100 and the IRL 20. See appendix A for cable part numbers. The maximum total distance between an Extron device (switcher, controller) and the IRL 20 is 150’ (45.7 m).
Quick Start Guide — IRL 20, cont’d communications connector. If desired, terminate the other end of the cable and plug it into a communications connector on an optional control module. Step 7 Verify correct wiring and cabling, and test the system: connect the devices to a power source, turn them on, aim an IR remote control at the IRL 20, and check for the appropriate response at the remotely controlled Extron device.

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.
1. This unit is not to be connected to a centralized DC power source or used beyond its rated voltage range. 2. The IRL 20 must be installed with accordance with the National Electrical Code and with local electrical codes.

Installation and Operation, cont’d 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.
