About the Soft Touch Power Button
In an ATX based system, the new soft touch power button
replaces the main power switch that turns your system on and
off. From an OFF state, you can switch the system ON by simply
pressing the power button. From an ON state, the system can
be turned OFF by pressing and holding the power button for four
(4) seconds OR shut down instantly. The functions of the power
button can also be altered in the Power Management section
of the CMOS setup.
C
Universal Serial Bus (USB) Connector
The Mainboard provides four 4-pin Universal Serial Bus
(USB) connectors. USB is a new interface standard for adding
external Plug-and-Play (PnP) devices to the computer system.
Peripherals that support USB PnP capabilities can operate at up
to a 12Mb/sec data transfer rate. Eventually, all external devices
connected to your computer will be standardized to USB.
D
Serial (COM1 & 2) Connector
The Mainboard provides two 9-pins serial port headers.
E
Infra-Red (IR) Connector
The Mainboard provides a 5-pin header interface, IR
for connection to a Hewlett Packard HSDSL-1000 compatible
infrared (IrDA) transmitter/receiver. Connect IR to the front panel
I/O IrDA connector provided with your system. Once the module
is connected to the front panel I/O IrDA connector, Serial port
2 can be re-directed to the IrDA module. When configured for
IrDA, the user can transfer files to or from portable devices such
as laptops, PDA’s and printers using application software such
as LapLink. The IrDA specification provides for data transfers
at 115 kbps from a distance of 1-meter. Support for Consumer
infrared (ASK-IR) is also included. Please refer to your IR
equipment for more detailed information.
