16) Internal Audio Connectors (4-pin CD_IN, AUX, VIDEO, MODEM)
These connectors allow you to receive stereo audio input from such sound sources
as a CD-ROM, TV tuner, or MPEG card. The MODEM connector allows the
onboard audio to interface with a voice modem card with a similar connector. It
also allows the sharing of mono_in (such as a phone) and mono_out (such as a
speaker) between the onboard audio and a voice modem card.

17) Standard and Consumer Infrared Module Connector (10-pin IR)
This connector supports an optional wireless transmitting and receiving infrared
module. This module mounts to a small opening on system cases that support
this feature. You must also configure the setting through UART2 Use Infrared
(see 4.4.2 I/O Device Configuration) to select whether UART2 is directed for
use with COM2 or IrDA. Use the five pins as shown in Back View and connect
a ribbon cable from the module to the motherboard’s SIR connector according
to the pin definitions. An optional consumer infrared (CIR) set connects to the
CIR and SIR connectors simultaneously for both wireless transmitting and re-
mote control functions through one external infrared module.
