ARK-2121F User Manual 2
1.1 Introduction
Advantech’s ARK-2121F is an intelligent, fanless embedded system with multiple I/O
powered by an Intel® Celeron™ J1900 Quad Core low-power processors. This new
generation of Intel® Celeron™ processor delivers a 300% processing power and
graphics performance increase when compared with Intel® Atom™ processors. This
low-power platform is designed for energy-efficient factory/machine automation,
kiosk, and self-service applications.This solution supports operation in -20 ~ 70 °C (-
4 ~ 158 °F) environments.
Rugged, Multi-functional Design
ARK-2121F embedded box PC features a rugged design, diverse expandability
options, and structural strengthening. This fanless solution supports wide-input
power supplies from 9 ~ 36Vdc. In addition, ARK-2121F enlarges the surface of the
top cover and conductive cylinder to optimize cooling efficiency. It has diverse I/O
interfaces — up to 6 x USB, 2 x GbE, 6 x COM, and supports high capacity 2.5" HDD
up to 1 TB. The RS-232/422/485 COM port mode can easily be changed via BIOS
settings.
Multiple Display Support
ARK-2121F supports two dual independent display interfaces: VGA, and HDMI. It
leverages a DirectX 11.1 graphics engine, H/W format decode/Acceleration, MPEG2
(H/W acceleration), H.264/ VC1/WMV9 (H/W Decode/Acceleration).
Built-in Intelligent Management Tools - Advantech iManager and SUSIAccess
Advantech iManager/SUSI 4.0 provides a valuable suite of programmable APIs such
as multi-level watchdog, hardware monitor, system restore, and other user-friendly
interfaces. iManager is an intelligent self-management cross platform tool that moni-
tors system status for problems and takes action during abnormalities. iManager/
SUSI 4.0 offers a boot up guarantee in critical, low temperature environments so sys-
tems can automatically recover when voltages dip. iManager/SUSI 4.0 makes the
whole system more reliable and intelligent. ARK-2121F also supports Advantech's
own SUSIAccess, which provides easy remote management so users can monitor,
configure, and control a large number of terminals to make maintenance and system
recovery simpler.

2.1 Introduction
The following sections show the internal jumpers setting and the external connectors
pin assignment for applications.
2.2 Jumpers
2.2.1 Jumper Description
You may configure ARK-2121F 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.
