1.5 ACPI Features
The Advanced Configuration and Power Interface (ACPI) specification defines a flexible and
abstract hardware interface that provides a standard way to integrate power management
features throughout a computer system, including its hardware, operating system and
application software. This enables the system to automatically turn on and off peripherals
such as CD-ROMs, network cards, hard disk drives and printers.
In addition to enabling operating system-directed power management, ACPI also provides a
generic system event mechanism for Plug and Play, and an operating system-independent
interface for configuration control. ACPI leverages the Plug and Play BIOS data structures,
while providing a processor architecture-independent implementation that is compatible with
Windows 2012/R2 and 2016 Server operating systems.
1.6 Power Supply
As with all computer products, a stable power source is necessary for proper and reliable
operation. It is even more important for processors that have high CPU clock rates. In areas
where noisy power transmission is present, you may choose to install a line filter to shield
the computer from noise. It is recommended that you also install a power surge protector to
help avoid problems caused by power surges. It is strongly recommended that you use a high
quality power supply that meets ATX power supply Specification 2.02 or above. It must also be
SSI compliant. For more information, please refer to the website at http://www.ssiforum.org/.
The X11SDW-4C/8C/12C/14C/14CNT/16C-TP13F motherboard supports an 8-pin 12V DC
input power supply at JPV1 for embedded applications. The 12V DC input is limited to 30A
by design. It provides up to 360W power input to the motherboard. Keep the onboard power
usage within the power limits specified above. Over current power usage may cause damage
to the motherboard.
1.7 Serial Port
The X11SDW-4C/8C/12C/14C/14CNT/16C-TP13F motherboard supports two serial
communication connections. COM Port 1 (RJ45 type) and COM Header 2 can be used for
input/output. The UART provides legacy speeds with a baud rate of up to 115.2 Kbps as well
as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which support high-speed
serial communication devices.
