15. Internal audio connectors (4-pin CD, AUX, MODEM)
(on audio models only)
These connectors allow you to receive stereo audio input from sound
sources such 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 a mono_out (such as a speaker) between the
audio and a voice modem card.
14. ASUS iPanel connector (24-1 pin AFPANEL)
This connector allows you to connect an optional ASUS iPanel, an
easy-to-access drive bay with front I/O ports and status LEDs. If you
are not using an ASUS iPanel, you can connect an optional wireless
transmitting and receiving infrared module to the SIR connector.
