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. The IR Learner features a built-in IR receiver, IR flasher, and five status indicators. A storage pouch and retractable USB extension cable are also included. Learning IR commands from a typical handheld remote is accomplished by simply pointing the remote at the IR receiver and following the instructions provided by the software tool. The software tool provides a comprehensive and easy-to-use utility for creating complete IR files, and adding them to the User Database for use with Crestron programming applications such as SIMPL Windows, SystemBuilder and D3 Pro. IR files can be tested by pointing the IR flasher toward the controlled device while triggering each command via the software tool. Extensive editing capabilities are provided in the Device Learner software tool to "fine-tune" each learned IR command for optimal functionality. Existing IR files from the User Database or Crestron Database can also be "auditioned" using the software tool and IR Learner to check for compatibility with a hardware device. Existing IR files can even be edited to alter their behavior or create new custom IR files using previously learned commands. New IR files may also be created by directly entering data in Philips Pronto CCF format.
