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-

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

1.1 Introduction
Advantech provides the smallest compact embedded computers on the market ---
the ARK-1300 series. These small, powerful all-in-one fanless systems are designed
for rugged and space critical applications in automation control and wireless gateway
applications. A solid sealed aluminum case provides vibration and water resistance
while also providing a passive cooling solution. The ARK-1380 provides system inte-
grators with a turn-key solution and versatile application development path without
breaking the bank or missing time to market deadlines
The ARK-1380 can be used as a standalone system, wall-mounted, DIN-rail
mounted or VESA mounted. The system accepts a wide range of power supplies (DC
power in) and comes in a footprint of only 189 x 41 x 136.5 mm (7.44" x 1.61" x
5.37"). The rugged cast aluminum case not only provides great protection from EMI,
shock/vibration, cold and heat, but also passive cooling for quiet fanless operation.
The ARK-1380 answers this demand by offering 4 x USB 2.0 ports, 1 x LVDS inter-
face, 1 x LAN port and 2 x COM ports; packed into a small rugged unit and powered
by an Intel Celeron M processor. Wireless connectivity can be added via the PC card
slot for PCMCIA or CardBus cards. It also supports a wide range of input voltages
from 9 VDC to 35 VDC. The ARK-1380 Compact Embedded Computer is equipped
with a solid state onboard CF card of up to 8 GB, so it easily passes 50 and 5 Grms
shock and vibration tests.

2.1 Introduction
The following two figures show the connectors on the ARK-1380. The following sec-
tions give you detailed information about the function of each peripheral.
2.2 Jumpers
2.2.1 Jumper Description
You can configure your ARK-1380 to match the needs of your application by setting
jumpers. A jumper is the simplest kind of electrical switch. 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 could connect either pins 1 and 2 or pins 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.

2.4.2 USB Connectors
The ARK-1380 provides four USB interface connectors, which give complete Plug &
Play and hot swapping for up to 127 external devices. The USB interface is compliant
with USB UHCI, Rev. 2.0. The USB interface can be disabled in the system BIOS
setup. Please refer to Table. 2.2 for its pin assignments.
The USB connectors are used for connecting any device that conforms to the USB
interface. Many recent digital devices conform to this standard. The USB interface
supports Plug and Play, which enables you to connect or disconnect a device when-
ever you want, without turning off the computer.
