Product Warranty (1 years)

Advantech warrants to you, the original purchaser, that each of its products will be
free from defects in materials and workmanship for two years from the date of pur­chase.

This warranty does not apply to any products which have been repaired or altered by
persons other than repair personnel authorized by Advantech, or which have been
subject to misuse, abuse, accident or improper installation. Advantech assumes no
liability under the terms of this warranty as a consequence of such events.

Because of Advantech’s high quality-control standards and rigorous testing, most of
our customers never need to use our repair service. If an Advantech product is defec­tive, it will be repaired or replaced at no charge during the warranty period. For out­of-warranty repairs, you will be billed according to the cost of replacement materials,
service time and freight. Please consult your dealer for more details.

If you think you have a defective product, follow these steps:

1. Collect all the information about the problem encountered. (For example, CPU

speed, Advantech products used, other hardware and software used, etc.) Note
anything abnormal and list any onscreen messages you get when the problem
occurs.

2. Call your dealer and describe the problem. Please have your manual, product,

and any helpful information readily available.

3. If your product is diagnosed as defective, obtain an RMA (return merchandise

authorization) number from your dealer. This allows us to process your return
more quickly.

4. Carefully pack the defective product, a fully-completed Repair and Replacement

Order Card and a photocopy proof of purchase date (such as your sales receipt)
in a shippable container. A product returned without proof of the purchase date
is not eligible for warranty service.

5. Write the RMA number visibly on the outside of the package and ship it prepaid

to your dealer.

This section provides instructions on how to configure your motherboard by setting
the jumpers. It also includes the motherboards's default settings and your options for
each jumper.

1.8.1 How to Set Jumpers

You can configure your motherboard to match the needs of your application by set­ting the jumpers. A jumper is a metal bridge that closes an electrical circuit. It consists
of two metal pins and a small metal clip (often protected by a plastic cover) that slides
over the pins to connect them. To “close” (or turn ON) a jumper, you connect the pins
with the clip. To “open” (or turn OFF) a jumper, you remove the clip. Sometimes a
jumper consists of a set of three pins, labeled 1, 2, and 3. In this case you connect
either pins 1 and 2, or 2 and 3. A pair of needle-nose pliers may be useful when set­ting jumpers.

1.8.2 CMOS Clear (JCMOS1)

The AIMB-203 motherboard contains a jumper that can erase CMOS data and reset
the system BIOS information. Normally this jumper should be set with pins 1-2
closed. If you want to reset the CMOS data, set CMOS1 to 2-3 closed for just a few
seconds, and then move the jumper back to 1-2 closed. This procedure will reset the
CMOS to its default setting.

1.9 System Memory

AIMB-203 has two sockets for a 204-pin DDR3 SODIMM. This socket uses a 1.5 V
unbuffered double data rate synchronous DRAM (DDR SDRAM). DRAM is available
in capacities of 1 GB, 2 GB, 4 GB and 8 GB. The sockets can be filled in any combi­nation with SODIMMs of any size, giving a total memory size between 1 GB, 2 GB, 4
GB, 8 GB and 16 GB. AIMB-203 does NOT support ECC (error checking and correc­tion).

1.10 Memory Installation Procedures

To install SODIMMs, slowly slide the SODIMM module along the plastic guides on
both ends of the socket. Then firmly but gently (avoid pushing down too hard) press
the SODIMM module well down into the socket, until you hear a click when the two
handles have automatically locked the memory module into the correct position of the
SODIMM socket. To remove the memory module, just push both handles outward,
and the memory module will be ejected by the mechanism.

The mission of Advantech Embedded Software Services is to "Enhance quality of life
with Advantech platforms and Microsoft® Windows® embedded technology." We
enable Windows® Embedded software products on Advantech platforms to more
effectively support the embedded computing community. Customers are freed from
the hassle of dealing with multiple vendors (hardware suppliers, system integrators,
embedded OS distributors) for projects. Our goal is to make Windows® Embedded
Software solutions easily and widely available to the embedded computing commu­nity.

4.2 Value-Added Software Services

Software API: An interface that defines the ways by which an application program
may request services from libraries and/or operating systems. Provides not only the
underlying drivers required but also a rich set of user-friendly, intelligent and inte­grated interfaces, which speeds development, enhances security and offers add-on
value for Advantech platforms. It plays the role of catalyst between developer and
solution, and makes Advantech embedded platforms easier and simpler to adopt and
operate with customer applications.

Chapter 4 Software Introduction & Service

A watchdog timer (WDT) is a device that performs a specific
operation after a certain period of time if something goes
wrong and the system does not recover on its own. A watch­dog timer can be programmed to perform a warm boot
(restarting the system) after a certain number of seconds.

The Hardware Monitor (HWM) API is a system health super­vision API that inspects certain condition indexes, such as
fan speed, temperature and voltage.

Makes use of Intel SpeedStep technology to save power con­sumption. The system will automatically adjust the CPU
speed depending on the system loading.

System Throttling

Refers to a series of methods for reducing power consump­tion in computers by lowering the clock frequency. This API
allows the user to adjust the clock from 87.5% to 12.5%.

Installation Utility

5.1 Before You Begin

To facilitate the installation of the enhanced display drivers and utility software, read
the instructions in this chapter carefully. The drivers for the AIMB-203 are located on
the software installation CD. The driver in the folder of the driver CD will guide and
link you to the utilities and drivers under a Windows system. Updates are provided
via Service Packs from Microsoft*.

Note! The files on the software installation CD are compressed. Do not

attempt to install the drivers by copying the files manually. You must use
the supplied SETUP program to install the drivers.

Before you begin, it is important to note that most display drivers need to have the
relevant software application already installed in the system prior to installing the
enhanced display drivers. In addition, many of the installation procedures assume
that you are familiar with both the relevant software applications and operating sys­tem commands. Review the relevant operating system commands and the pertinent
sections of your application software’s user manual before performing the installa­tion.

5.2 Introduction
