(behind the panel) — The sensors that receive incoming IR signals are behind the red, plastic, front panel lens near the middle; toward the left is a green LED that blinks when an IR signal is received by the IRL 20. The angles (+/- 40°) and maximum distance (up to 30') recommended for best reception of incoming signals are shown in the illustration at right.

Communications connector — Use this

10-pole connector to connect the IRL 20 to other Extron devices. Both halves of the connector function the same way (either can be used as an input or an output), so they are interchangeable.

Install a 3.5 mm, 5-pole captive screw connector on one end of an Extron Comm-Link cable, and plug it into the left or the right half of this connector. Wire both ends of the cable identically (ground pin to ground pin, modulated IR to modulated IR, etc.). Plug the other end of the cable into the appropriate connector on an Extron MediaLink Controller (MLC), MediaLink Switcher, System 5 IP Switcher, or AVT 100.

The Extron IRL 20 is an infrared lighting system designed to deliver high-performance IR signals for controlling AV devices. One of its primary features is its ability to provide reliable, long-range IR communication, which is essential in environments where line-of-sight control may be obstructed. The IRL 20 boasts a broad coverage area, ensuring consistent performance even in larger spaces. This capability is augmented by the system's dual IR emitters, allowing for enhanced signal strength and improved reliability.

Key technologies incorporated in the IRL 20 include a stable LED light source that ensures optimal performance across various distances. This innovation helps maintain signal integrity and minimizes potential interference from other electronic devices. Additionally, the IRL 20 is compatible with a range of Extron’s control processors, providing seamless integration into existing AV control systems.

On the other hand, the Extron IR 102 serves as a versatile infrared receiver. It is equipped to decode incoming IR signals and transmit commands to connected devices, making it an essential component in any automated AV environment. The IR 102 features a streamlined design that can easily blend into any installation, promoting a clean and unobtrusive appearance.

Among the main characteristics of the IR 102 is its ability to support multiple IR codes, allowing users to control a variety of devices simultaneously. The unit's high sensitivity ensures it can pick up signals even when at a distance, enhancing the convenience of use. Moreover, both the IR 102 and IRL 20 have been designed with ease of installation in mind, featuring standard mounting options and simple wiring connections.

In summary, the Extron IRL 20 and IR 102 provide powerful solutions for infrared communication in audiovisual applications. Their advanced technologies, reliable performance, and compatibility with other Extron systems make them ideal for enhancing user experience in commercial and educational settings. With their focus on innovation, Extron continues to lead the way in the field of AV control solutions.
