Extron electronic MLC 52 manual Wiring an IRL

Wiring an IRL 20

The Extron IRL 20 is a hard wired IR signal receiver that can be used with the MLC 52 and an IR remote control. The IRL 20 receives a signal via its front panel (or an IR sensor) from the IR remote control, and outputs a modulated IR signal via an IR emitter.

Wire and connect the IRL 20 to the MLC 52 as follows:

1.If it has not been done, cut the required length of Extron CTL (Comm-Link) cable to connect the MLC 52 to the IRL 20 (see Recommended Cables on page 62 for cable part numbers).

The maximum total distance between an Extron controller and the IRL 20 is 150 feet (45.7 m).

2.Attach a 3.5 mm, 5-pole captive screw connector to the end of the cable that will be plugged into the IRL 20.

•C (MLC) to D (IRL 20)

NOTE: Do not connect more than one IRL 20 (either in parallel or in series) to an Extron device.

4.Plug the 5-pole connector end of the cable into one of the IRL 20 communications connectors.

5.Plug the 6-pole connector end of the cable into the control port on the MLC 52 back panel.

6.Connect power to the MLC or the IRL 20.

NOTE: The +12 VDC power is shared between the MLC 52 and the IRL 20 when they are connected. You can wire the power supply to either the MLC or the IRL 20.
