Product Warranty (2 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 pur-
chase.
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 defec-
tive, it will be repaired or replaced at no charge during the warranty period. For out-
of-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 merchandize
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

SOM-5893 User Manual 2
1.1 Introduction
SOM-5893 is a COM-Express basic pin-out Type 6 module that complies with the
PICMG (PCI Industrial Computer Manufacturers Group) COM.0 R2.1 specification.
The CPU module comprises a second-generation AMD embedded R-series APU,
FCH A77E, and other peripheral chips to provide COM-specific functionalities. The
latest AMD APU supports HeteoHSA.
SOM-5893 can support four independent symmetrical displays (LVDS, DDI, and
VGA) of up to 4K2K DDI resolution, enabling users to set diverse combinations of
simultaneous displays. With a next-generation AMD Radeon HD9000 graphics card,
DX11.1 support, OpenCL 1.2, OpenGL 4.2, and a H.264 and MPEG4 decoder, this
module offers enhanced media effects and outstanding 3D performance. Built-in high
speed I/O ports include USB 3.0 and SATAIII for transmitting big data. The PEG x16
lane with up to Gen3 compliance (8 GT/s bit rate) and 7 PCIe x1 can be configured
according to users’ applications via the BIOS Setup utility.
Advantech’s iManager 2.0 was developed to facilitate many embedded application
functions, such as a multi-level watchdog timer, voltage and temperature monitoring,
thermal protection and mitigation through processor throttling, LCD backlight on/off
and brightness control, and embedded storage for customized information.
SUSIAccess, Advantech’s remote management software, allows devices to be moni-
tored and controlled remotely over the Internet for easy maintenance. All Advantech
COM-Express modules are integrated with iManager and SUSIAccess to enhance
customer applications.
The high performance, embedded platform-level power consumption, and diverse
extensions and I/O interfaces of SOM-5893 make it suitable for computing-intensive,
thermally sensitive, graphics/media-intensive designs, and I/O-demanding applica-
tions.

3.1 Introduction
SOM-5893 BIOS has been stored in a flash ROM which is inserted into a BIOS
socket on the board. With the BIOS Setup program, users can modify BIOS settings
and control various system features. This chapter describes the basic navigation of
the SOM-5893 BIOS setup screens.
Advantech will supply BIOS revisions for product optimization, and users can re-flash
the latest BIOS through the AFU utility. Please contact Advantech support for details.
Figure 3.1 BIOS Setup Utility Main Screen
SOM-5893 BIOS has a built-in Setup program that allows users to modify the basic
system configuration. This information is stored in flash ROM so it retains the Setup
information when the power is turned off.
