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).
