1 General Introduction
This chapter gives background
information on 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 targeted at factory
automation, machine automation, kiosks, and self-service applications.
Rugged & Multifunctional 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: 2 x USB 3.0, 4 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 with
an expansion display module, it can provide DP, HDMI, DVI-D as the 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 show the internal jumpers settings and the external connector
pin assignments for application.
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.
