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).

Step 3

For switchers or an AVT 100, attach a 3.5 mm, 5-pole captive screw

connector to each end of the cable.	+12V	GND	CM	ModIR	SCP	+12V	G	CM	ModIR
For MediaLink controllers, attach a 3.5 mm,							ND
5-pole captive screw connector to the end of
the cable that will be plugged into the IRL 20.

Only three wires are required for most applications, but use four wires if the IRL 20 will be daisy chained with

MediaLink Control Modules. Refer to the device’s manual and chapter 2 for details on ports and pin assignments.

Do not connect

more than one IRL 20 or IR Link (either in parallel or in series) to an Extron device. Also, read the user’s or installation manual for each product to determine the maximum quantity of control modules that can be used.

Step 4

Plug the terminated cable to one of the IRL 20’s rear panel communications connectors.

Step 5

Plug the other end of the cable into the appropriate port of the switcher, controller, control module, or AVT. Refer to the device’s manual for details on ports and pin assignments. Wire both ends of the cable identically (ground to ground, signal to signal, and so forth).

Step 6

Attach a captive screw connector to another length of Comm-Link cable as in step 3, then plug it into the IRL 20’s remaining
