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.

1 General Introduction

This chapter gives background

information on ARK-1550 series.

ARK-1550 User Manual 2

1.1 Introduction

ARK-1550 Fanless Embedded Box PC is an application ready system platform solu-

tion. All electronics are protected in a compact sealed aluminum case for easy inte-

gration in the customer's own housing, or as a stand-alone application, where space

is limited and the environment harsh. ARK-1550 is a new single board design made

very slim. The dimensions are only 223 x 46.6 x 133.0 mm. ARK-1550 can be easily

integrated with panel/displays within limited spaces and can be installed anywhere

due to its slim dimensions with optional DIN rail and VESA mounting solutions.

ARK-1550 optimizes space and offers 2*USB 2.0, 2*USB 3.0, 1*VGA, 1*HDMI,

1*LVDS(optional), 3*COM, 1*DIO, 2*GbE LANs and 1*hot swappable 2.5" drive bay.

Also, ARK-1550 can provide 2*MiniPCIe slot for future extensions. The ARK-1550

compact design can provide up to 5 Grms vibration and 50G shock protections and

wide temperature support from -20-55 °C under harsh environment.

ARK-1550 is powered by 12V DC input and adopts the latest Intel 4th generation

core i5 4300U DC 1.9 GHz and Celeron 2980U DC 1.6 GHz CPUs which meet most

requirements. ARK-1550 is the ideal choice for cost/performance value for custom-

ers.

ARK-1550 User Manual 8

2.1 Introduction

The following sections show the internal jumper settings and the external connectors

and pins assignment for applications.

2.2 Jumpers

2.2.1 Jumper List

The ARK-1550 has a number of jumpers that allow you to configure your system to

suit your application. The table below lists the functions of the various jumpers.

2.2.2 Jumper Settings

Cards can be configured 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.

ARK-1550 comes with a Power On/Off button, that support dual function of Soft

Power -On/Off (Instant off or Delay 4 Second), and Suspend.

Figure 2.3 Power ON/OFF Button

2.4.2 Power Input Connector

ARK-1550 comes with a DC-Jack header that carries 12 V

external power input.

The power connector can be fixed by a bracket which is in the accessory box. The

bracket prevents the power connector falling off.

2.4.3 Ethernet Connector (LAN)

ARK-1550 provides two RJ45 LAN interface connectors, which are fully compliant

with IEEE 802.3u 10/100/1000 Base-T CSMA/CD standards. LAN1 is equipped with

Intel I218 GbE and LAN2 is equipped with Intel I210 GbE. The Ethernet ports use

standard RJ-45 jack connectors with LED indicators on the front side to show Active/

Link status and Speed status.
