The UCM/ETH03 and UCM/USB is able to learn most Infrared signals from handheld remote controllers to be saved in the Infrared code library in Comfort. The IR Codes in the library can be sent to any Output connected to an Infrared Transmitter IRM01, IR01W, IR03W. See Output actions at http://www.comfortforums.com/forum92/4291.html


This information is also found in the UCM Manual

Definitions
Ifr file
A .ifr file contains the encoded infrared data for the commands for a specific appliance. For example, a TV file may have On/OFF, Channel 1, Channel 2, Mute, etc.. Each  command in the ifr file can be assigned as an IR Transmit code and downloaded to  Comfort via Comfigurator to be sent to any output using Infrared Command

The commands in an ifr file can be learned with the infrared learner software in Comfigurator. The .ifr files are contained in the ifr sub directory in the Comfigurator directory.


Specification
  • Infrared Carrier Frequency: 35 kHz to 50 kHz
  • Learning distance: 5 to 10 cm.
  • Angle for reception: +/- 25 degrees
  • Encoding: ifr format
Limitations
Some infrared signals cannot be captured or encoded by the software algorithm or used by Comfort because of limitations in the encoding system. The IR learner captures and encodes the IR signals, while Comfort decodes the encoded signals to transmit from any programmed output. The process of encoding and decoding will introduce errors between the reconstructed signal and the original signal. This works well in the majority of remote control signals tested, but not for all possible remote controls.
