UNO-238 User Manual 2
1.1 Introduction
Advantech’s new UNO-200 series focuses on IT level applications which only require
semi-industrial design and cost efficiency.
New UNO-238 model aims to provide an optimized design with the 8th generation
CPU Intel® Core™ U-Series processor. UNO-238 is IT-oriented, fanless, with IoT
edge computing features and sufficient connectivity including 2 x LAN, 2 x RS- 232/
422/485, 1 x GPIO, 4 x USB 3.2, 1 x DP 1.2, 1 x HDMI 1.4 and 1 x Audio. It also sup-
ports 2 x M.2 and 1x Nano SIM card slot for expansion to fulfill various requirements
for industrial applications.
1.2 Safety Precautions
Below are a few safety precautions for preventing injury when making connections. In
most cases, users can use a standard cable for connection.
Warning! Always disconnect the power cord from the chassis before manual han-
dling. Do not connect the chassis while the system power is on. A sud -
den rush of power can damage sensitive electronic components. Only
experienced electronics personnel should open the chassis.
Warning! Toujours à la terre pour éliminer toute charge d'électricité statique avant
toucher UNO-238. Appareils électroniques modernes sont très sensi-
bles à charges d'électricité statique. Utilisez un bracelet antistatique à
tout moment. Placez tous composants électroniques sur une surface
antistatique ou dans un statique-sac blindé.
Caution! Always ground yourself to remove any static electric charge before
touching UNO-238. Modern electronic devices are very sensitive to
static electric charges. Use a grounding wrist strap at all times. Place all
electronic components on a static-dissipative surface or in a static
shielded bag.
Caution! Toujours débrancher le cordon d'alimentation de votre boîtier lorsque
vous êtes travailler. Ne branchez pas lorsque l'appareil est allumé. Un
afflux soudain de puissance peut endommager les composants électro-
niques sensibles. Seulement connu personnel de l'électronique
devraient ouvrir le châssis.

2.2.1 Power Connector
UNO-238 comes with a Lockable DC jack that carries 12 VDC external power input,
and features reversed wiring protection. Therefore, it will not cause any damage to
the system by reversed wiring of ground and power lines.
2.2.2 LAN: Ethernet Connector
UNO-238 is equipped with two Gigabit LAN controllers. (LAN1: Intel® i219; LAN2:
Intel® i210-IT) that complies with IEEE 802.3u 10/100/1000 Base-T is used as the
controller chip.
2.2.3 USB Connector
UNO-238 features 4 USB ports that comply with USB 3.2 specifications. The USB
connectors support plug-and-play and hot-swapping functionality for external devices
without turning off the computer. It can also be enabled/disabled in the BIOS menu as
well.
2.2.4 DisplayPort Connector
The UNO-238 provides 1 x DP 1.2 connector for a high resolution interface up to
4096 x 2160 @ 60Hz, It also supports DP++ that is compatible with passive adapters.
