Consumer IR (CIR) Headers
The Desktop Board has two CIR headers: the input or receiver header (Figure 23, F)
and the output or emitter header (Figure 23, 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.
