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 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.

ARK-3390 User Manual 2
1.1 Introduction
ARK-3390 fanless Embedded Box Computer is an ideal application ready system
platform solution. All electronics are protected in a compact, sealed, aluminum case
for easy embedding in the customer’s own housing, or as a stand-alone application
where space is limited and the environment harsh.
A solid sealed aluminum case provides vibration and dust resistance while also pro-
viding a passive cooling solution. The ARK-3390 provides system integrators with a
turn-key solution and versatile application development path without breaking the
bank or missing time to market deadlines.
The ARK-3390 can be used as a standalone system, wall- or DIN-rail- mounted. The
system accepts a wide range of power supplies (DC power in) and comes in a foot-
print of only 264.5 x 69.2 x 137.25 mm (10.41" x 2.72" x 5.4"). The rugged cast alumi-
num case not only provides great protection from EMI, shock/vibration, cold and
heat, but, as we mentioned before, passive cooling for quiet fanless operation.
The ARK-3390 answers demands by offering 1 x VGA and 1 x DVI interface for dual
display, 5 x USB 2.0 ports, 2 x Giga LAN port and 6 x COM ports; packed into a small
rugged unit and powered by an Intel Core Duo processor. It also supports a wide
range of input voltages from 9 VDC to 34 VDC. The ARK-3390 Compact Embedded
Computer supports both 2.5” SATA HDD and Compact Flash card for storage options
and it provides for diversified application fields.

2.1 Introduction
The following sections show the internal jumpers setting and the external connectors
pin assignment for application.
2.2 Jumpers
2.2.1 Jumper Description
You may configure the ARK-3390 to match the needs of your application by setting
jumpers. A jumper is a metal bridge used to close an electric 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 a jumper, you connect the pins with the clip. To
open a jumper, you remove the clip. Sometimes a jumper will have three pins,
labeled 1, 2 and 3. In this case you would connect either pins 1 and 2, or 2 and 3.
The jumper settings are schematically depicted in this manual as follows.
A pair of needle-nose pliers may be helpful when working with jumpers. If you have
any doubts about the best hardware configuration for your application, contact your
local distributor or sales representative before you make any changes. Generally, you
simply need a standard cable to make most connections.
