The Crestron® CSP-LIR-USB IR Learner is a compact USB device that works in conjunction with the Device Learner software tool (part of Crestron Toolbox™) to provide a complete solution for creating, editing, testing, and managing IR device control files for use in programming a Crestron control system. The IR Learner simply plugs into the USB host port of a laptop computer running Crestron Toolbox software, providing the essential interface for learning IR commands from a third-party remote, and testing the learned commands with the device they control.
