Consumer IR (CIR) Headers 
The Desktop Board has two CIR headers: the receiver or input header (Figure 20, C) 
and the output or emitter header (Figure 20, D).  The receiver header consists of a 
filt
ered translated infrared input compliant with Microsoft CIR specifications and a 
“learning” infrared input.  The learning input is 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 computer can use 
to emulate “learned” infrared commands in order to control external electronic 
hardware. 
 
NOTE 
The Consumer IR option must be enabled in the system BIOS before it can 
function.  Press <F2> at boot to enter the system BIOS, and go to Advanced > 
Peripheral Configuration > Enhanced Consumer IR, and set this option to 
Enabled.
