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 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 a return merchandise authori-

zation (RMA) 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.

1 General Introduction

This chapter gives background
information on the ARK-2250
series.

1.1 Introduction

ARK-2250 is an intelligent, modular, and fanless embedded system. A fully modular
design, ARK-2250 supports easy I/O switching with optional iDoor modules, wide
range power board, and MIOe board expansions. ARK-2250 is aimed at factory auto­mation, machine automation, kiosks, and self-service applications.

Rugged, Multi-functional Design

ARK-2250 embedded box PC is powered by an Intel 6th gen core i3/i7 processor.
The compact size system provides a selection of I/O ports: 4 x USB 3.0, 2 x USB 2.0,
2 x GbE, 4 x COM, 2 x mPCIe and 1 x 2.5" HDD. The default power input is 12V DC
in, and it also supports an optional wide range 9~36V power module with wide tem­perature operation of -20 to 60C. ARK-2250 passes worldwide certification including
CE/FCC, CB, UL, CCC and BSMI.

Multiple Display Support

ARK-2250 supports up to 3 display types: VGA, HDMI as the default display, and an
expansion display module. It can also provide DP, HDMI, DVI-D as a 3rd optional dis­play port. The graphic engine is DirectX 11.3, OpenGL 4.4, and OpenCL 2.1 Full
AVC/VC1/MPEG2 HW Decode.

Built-in Intelligent Management Tools — WISE-PaSS/RMM

Advantech WISE-PaSS/RMM provides a valuable suite of programmable APIs such
as multi-level watchdog, hardware monitor, system restore, and other user-friendly
interface. iManager is an intelligent self-management cross platform tool that moni­tors system status for problems and takes action if anything is abnormal. It offers a
boot up guarantee in critical, low temperature environments so systems can automat­ically recover when voltages dip. WISE-PaSS/RMM makes the whole system more
reliable and more intelligent. ARK-2250L provides easy remote management so
users can monitor, configure, and control a large number of terminals to make main­tenance and system recovery simpler.

The following sections detail the internal jumpers settings and the external connector
pin assignments for different applications.

2.2 Jumpers

2.2.1 Jumper Description

You may configure ARK-2250 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.
