To install the cable that connects your front panel audio solution to the front panel

audio header, follow these steps:

1. Observe the precautions in "Before You Begin" on page 27.

2. Turn off all peripheral devices connected to the computer. Turn off the computer

Consumer IR (CIR) Headers

The Desktop Board has two CIR headers: the receiver or input header (Figure 17, F)

and the output or emitter header (Figure 17, C). The receiver header consists of a

filtered 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.
