Introduction
S/PDIF
S/PDIF is a standard audio file transfer format that transfers digital audio sig-
nals to a device without having to be converted first to an analog format. This
prevents the quality of the audio signal from degrading whenever it is converted
to analog. S/PDIF is usually found on digital audio equipment such as a DAT
machine or audio processing device. The S/PDIF connector on the system board
sends surround sound and 3D audio signal outputs to amplifiers and speakers
and to digital recording devices like CD recorders.
Serial ATA
Serial ATA is a storage interface that is compliant with SATA 1.0a specification.
With speed of up to 3Gbps, it improves hard drive performance faster than the
standard parallel ATA whose data transfer rate is 100MB/s.
Gigabit LAN
The PCI Express Gigabit controllers support up to 1Gbps data transmission.
USB
The system board supports USB 2.0 and USB 1.1 ports. USB 1.1 supports 12Mb/
second bandwidth while USB 2.0 supports 480Mb/second bandwidth providing a
marked improvement in device transfer speeds between your computer and a
wide range of simultaneously accessible external Plug and Play peripherals.
Wake-On-Ring
This feature allows the system that is in the Suspend mode or Soft Power Off
mode to wake-up/power-on to respond to calls coming from an external modem
or respond to calls from a modem PCI card that uses the PCI PME (Power Man-
agement Event) signal to remotely wake up the PC.
Important:
The 5V_standby power source of your power supply must support
≥720mA.
