Connecting an IRL 20 to a MediaLink switcher or controller, an AVT 100, or another Extron product

The IRL 20 can be connected directly to a MediaLink switcher, System 5 IP switcher, or AVT tuner. Also, it can either be connected directly to an MLC or be part of a daisy chain of MediaLink Control Modules connected to an MLC.

1.If it hasn’t already been done, 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 m).

2. For switchers or an AVT, attach a 3.5 mm, 5-pole captive

screw connector to each end of the cable. Only three wires

(pins C, , and + on the switcher/AVT end) are required.

For MediaLink controllers, attach a 3.5 mm, 5-pole

captive screw connector to the end of the cable that will be

plugged into the IRL 20, and connect wires on the other

end of the cable to the MLC’s IR/RCM or CM/IR/SCP

direct insertion captive screw connector. Wire both ends of

the cable identically (ground to ground, signal to signal,

and so forth).

Only three wires are required, but use four wires if the

IRL 20 will be daisy chained with MediaLink Control

Modules. Refer to the device’s manual 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.

3.Plug the 5-pole connector into one of the IRL 20’s communications connectors.

4.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.

Do not connect more than one (1) IRL 20 (either in parallel or in series) to a switcher. Also, read the user’s or installation manual for each product to determine the maximum quantity of control modules that can be used.

5.Plug one end of another cable into the IRL 20’s remaining communications connector. Plug the other end of the cable into a communications connector on an optional control module.

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).
