1.7.1 Consumer Infrared (CIR)
The Consumer Infrared (CIR) feature is designed to comply with Microsoft Consumer
Infrared usage models.
The CIR feature is made up of two separate pieces: the receiving (receiver) header,
and the output (emitter) header. The receiving header consists of a filtered translated
infrared input compliant with Microsoft CIR specifications, and also a “learning”
infrared input. This learning input is simply a high pass input which the computer can
use to “learn” to speak the infrared communication language of other user remotes.
The emitter header consists of two output ports which the PC can use to emulate
“learned” infrared commands in order to control external electronic hardware.
Customers are required to buy or create their own interface modules to plug into Intel
Desktop Boards for this feature to work.
