About this Manual
This manual can be downloaded from the website.
The manual is subject to change and update without notice, and may be based on editions
that do not resemble your actual products. Please visit our website or contact our sales
representatives for the latest editions.
Warranty
1. Warranty does not cover damages or failures that arise from misuse of the product,
inability to use the product, unauthorized replacement or alteration of components and
product specifications.
2. The warranty is void if the product has been subjected to physical abuse, improper
installation, modification, accidents or unauthorized repair of the product.
3. Unless otherwise instructed in this user’s manual, the user may not, under any
circumstances, attempt to perform service, adjustments or repairs on the product,
whether in or out of warranty. It must be returned to the purchase point, factory or
authorized service agency for all such work.
4. We will not be liable for any indirect, special, incidental or consequential damages to
the product that has been modified or altered.
Static Electricity Precautions
It is quite easy to inadvertently damage your PC, system board, components or devices even
before installing them in your system unit. Static electrical discharge can damage computer
components without causing any signs of physical damage. You must take extra care in
handling them to ensure against electrostatic build-up.
1. To prevent electrostatic build-up, leave the system board in its anti-static bag until you
are ready to install it.
2. Wear an antistatic wrist strap.
3. Do all preparation work on a static-free surface.
4. Hold the device only by its edges. Be careful not to touch any of the components,
contacts or connections.
5. Avoid touching the pins or contacts on all modules and connectors. Hold modules or
connectors by their ends.
Important:
Electrostatic discharge (ESD) can damage your processor, disk drive and other
components. Perform the upgrade instruction procedures described at an ESD
workstation only. If such a station is not available, you can provide some ESD
protection by wearing an antistatic wrist strap and attaching it to a metal part
of the system chassis. If a wrist strap is unavailable, establish and maintain
contact with the system chassis throughout any procedures requiring ESD
protection.
Safety Measures
• To avoid damage to the system, use the correct AC input voltage range.
• To reduce the risk of electric shock, unplug the power cord before removing the
system chassis cover for installation or servicing. After installation or servicing, cover
the system chassis before plugging the power cord.

XFeatures
Watchdog Timer
The Watchdog Timer function allows your application to regularly “clear” the system at the set
time interval. If the system hangs or fails to function, it will reset at the set time interval so that
your system will continue to operate.
DDR4
DDR4 delivers increased system bandwidth and improves performance. The advantages of
DDR4 provide an extended battery life and improve the performance at a lower power than
DDR3/DDR2.
Graphics
The integrated Intel®HD graphics engine delivers an excellent blend of graphics performance
and features to meet business needs. It provides excellent video and 3D graphics with
outstanding graphics responsiveness. These enhancements deliver the performance and
compatibility needed for today’s and tomorrow’s business applications.
Gigabit LAN
The Gigabit Ethernet Controllers support data transmission at 1Gbps.
Audio
The audio codec provides 5.1 channel High Definition audio output.
Wake-On-LAN
This feature allows the network to remotely wake up a Soft Power Down (Soft-Off) PC. It is
supported via the onboard LAN port or via a PCI LAN card that uses the PCI PME (Power
Management Event) signal. However, if your system is in the Suspend mode, you can power-on
the system only through an IRQ or DMA interrupt.
Wake-On-USB
This function allows you to use a USB keyboard or USB mouse to wake up a system from the
S3 (STR - Suspend To RAM) state.
ACPI STR
The system board is designed to meet the ACPI (Advanced Configuration and Power
Interface) specification. ACPI has energy saving features that enables PCs to implement
Power Management and Plug-and-Play with operating systems that support OS Direct Power
Management. ACPI when enabled in the Power Management Setup will allow you to use the
Suspend to RAM function.
With the Suspend to RAM function enabled, you can power-off the system at once by pressing
the power button or selecting “Standby” when you shut down Windows®without having to go
through the sometimes tiresome process of closing files, applications and operating system.
This is because the system is capable of storing all programs and data files during the entire
operating session into RAM (Random Access Memory) when it powers-off. The operating
session will resume exactly where you left off the next time you power-on the system.
Power Failure Recovery
When power returns after an AC power failure, you may choose to either power-on the system
manually or let the system power-on automatically.
USB
The system board supports the new USB 3.1 Gen 2. It is capable of running at a maximum
transmission speed of up to 10 Gbit/s (1.2 GB/s) and is faster than USB 3.1 Gen 1 (5 Gbit/s, or
625 MB/s), USB 2.0 (480 Mbit/s, or 60 MB/s) and USB 1.1 (12Mb/s). USB 3.1 reduces the time
required for data transmission, reduces power consumption, and is backward compatible with
USB 2.0. It is a marked improvement in device transfer speeds between your computer and a
wide range of simultaneously accessible external Plug and Play peripherals.
RTC Timer
The Real Time Clock (RTC) installed on the system board allows your system to automatically
power-on on the set date and time.

Note:
Some components are optional and only available upon request.
Important:
Electrostatic discharge (ESD) can damage your board, processor,
disk drives, add-in boards, and other components. Perform
installation procedures at an ESD workstation only. If such a
station is not available, you can provide some ESD protection by
wearing an antistatic wrist strap and attaching it to a metal part
