15. ASUS iPanel connector (24-1 pin AFPANEL) (optional)
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.
16. Digital audio connector (6-1 pin SPDIF_C) (on audio models only)
This connector is for the bundled S/PDIF audio module that allows
digital instead of analog sound output. Connect one end of the audio
cable to the S/PDIF In/Out connector on the motherboard, and the
other end to the S/PDIF module.
