FCC and DOC Statement on Class A

This equipment has been tested and found to comply with the limits for a Class B digital

device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reason-

able protection against harmful interference when the equipment is operated in a residential

installation. This equipment generates, uses and can radiate radio frequency energy and, if not

installed and used in accordance with the instruction manual, may cause harmful interference

to radio communications. However, there is no guarantee that interference will not occur in a

particular installation. If this equipment does cause harmful interference to radio or television

reception, which can be determined by turning the equipment off and on, the user is encour-

aged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and the receiver.

• Connect the equipment into an outlet on a circuit different from that to which the receiver

is connected.

• Consult the dealer or an experienced radio TV technician for help.

Notice:

1. The changes or modifications not expressly approved by the party responsible for compli-

ance could void the user’s authority to operate the equipment.

2. Shielded interface cables must be used in order to comply with the emission limits.

Static Electricity Precautions

It is 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 compo-

nents 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 con

nectors by their ends.

Safety Measures

To avoid damage to the system:

• Use the correct DC input voltage range.

To reduce the risk of electric shock:

• Unplug the power cord before removing the system chassis cover for installation or servic-

ing. After installation or servicing, cover the system chassis before plugging the power cord.

Battery:

• Danger of explosion if battery incorrectly replaced.

• Replace only with the same or equivalent type recommend by the manufacturer.

• Dispose of used batteries according to local ordinance.

About this Manual

the Download Center page, select your product or type the model name and click "Search" to

nd all technical documents including the user's manual for a specic product.

Warranty

1. Warranty does not cover damages or failures that arises from misuse of the product, in-

ability 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 instal-

lation, modification, accidents or unauthorized repair of the product.

3. Unless otherwise instructed in this user’s manual, the user may not, under any circum-

stances, 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.

Important:

Electrostatic discharge (ESD) can damage your processor, disk drive and other com-

ponents. Perform the upgrade instruction procedures described at an ESD worksta-

tion 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 chas-

sis. If a wrist strap is unavailable, establish and maintain contact with the system

chassis throughout any procedures requiring ESD protection.

About the Package

The package contains the following items. If any of these items are missing or damaged,

please contact your dealer or sales representative for assistance.

• GM831-CSF system unit

• Power Supply (PSU)

• CD disk includes

- Manual

- Drivers

• Quick Installation Guide

The board and accessories in the package may not come similar to the information listed

above. This may differ in accordance to the sales region or models in which it was sold. For

more information about the standard package in your region, please contact your dealer or

sales representative.

Before Using the System

Before powering-on the system, prepare the basic system components.

If you are installing the system for the first time, you will need at least one of the following

internal components.

• Storage devices such as SATA HDD or M.2 modules.

You will also need external system peripherals, which will normally include at least a keyboard,

a mouse and a video display.

Safety Precautions

• Keep this system away from humidity.

• Place the system on a stable surface. Dropping it or letting it fall may cause damage.

• The openings on the system are for air ventilation to protect the system from overheating.

DO NOT COVER THE OPENINGS.

• Place the power cord in such a way that it will not be stepped on. Do not place anything on

top of the power cord. Use a power cord that has been approved for use with the system

and that it matches the voltage and current marked on the system’s electrical range label.

• If the system will not be used for a long time, disconnect it from the power source to avoid

damage by transient overvoltage.

• If one of the following occurs, consult a service personnel:

- The power cord or plug is damaged.

- Liquid has penetrated the system.

- The system has been exposed to moisture.

- The system is not working properly.

- The system dropped or is damaged.

- The system has obvious signs of breakage.

• The unit uses a three-wire ground cable which is equipped with a third pin to ground the

unit and prevent electric shock. Do not defeat the purpose of this pin. If your outlet does

not support this kind of plug, contact your electrician to replace the outlet.

• Disconnect the system from the DC outlet before cleaning. Use a damp cloth. Do not use

liquid or spray detergents for cleaning.

This section gives a high level overview the functionalities and process ow of the APIs. The fol-

lowing table outlines the names of the APIs and their usage.

MCU

The set of APIs can be categorized into 8 groups:

In Windows, the Intru-Processor API is called DFIGamingIntru.dll which accesses the serial

port with the library DFISerailPort.dll. Both of the libraries have to be together with AP in the

same folder.

In Linux, the Intru-Processor API is called DFIGamingIntru.so which accesses the serial port

with t he library DFISerailPort.so. Both of the libraries have to be put to /usr/lib.
