Product Warranty (2 years)
Advantech warrants 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 that have been repaired or altered by
persons other than repair personnel authorized by Advantech, or products that 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
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 out-of-war-
ranty repairs, customers are billed according to the cost of replacement materials,
service time, and freight. Please consult your dealer for more details.

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 on-screen messages displayed when the prob-
lem 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 merchandize
authorization (RMA) number from your dealer. This allows us to process your
return more quickly.
4. Carefully pack the defective product, a completed Repair and Replacement
Order Card, and a proof of purchase date (such as a photocopy of your sales
receipt) into a shippable container. Products returned without a proof of

UNO-2372G-J1 User Manual 2
1.1 Introduction
Advantech’s next-generation UNO-2000 series of embedded automation computers
feature highly ruggedized, modular, fanless designs. UNO-2372G-J1’s excellent
modularity provides numerous performance and cost-saving advantages, including
the elimination of unnecessary features and expenses, accelerated UNO-2372G-J1
production and delivery, rapid deployment and integration, reduced system downtime
and maintenance costs, and support for future upgrades and expansion. The UNO-
2372G-J1 is equipped with optimized I/O and an optional second expansion stack
that supports Advantech’s iDoor technology. This enables easy extension and cus-
tomization with the integration of various iDoor modules. These modules include
industrial Fieldbus, wireless communication, I/O, and peripheral modules. This solu-
tion facillitates purpose-built, future-proof solutions that satisfy specific application
requirements.
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-2372G-J1. Appareils électroniques modernes sont très
sensibles à charges d'électricité statique. Utilisez un bracelet antista-
tique 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-2372G-J1. 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.

Chapter 2 Hardware Functionality
2.2 Serial Communication Ports
The UNO-2372G-J1 features four standard COM serial communication ports: COM1,
COM2, COM3, and COM4.
2.2.1 COM Port Interfaces (COM1, COM2, COM3, COM4)
The UNO-2372G-J1 is also equipped with four RS-232/422/485 ports (DB9, 50 ~
115.2 kbps). The default setting for COM1 ~ 4 is RS-232. These settings can be
adjusted in the BIOS menu.
2.3 LAN: Ethernet Connector
UNO-2372G-J1 is equipped with two Gigabit LAN controllers. An Intel® i210 Ethernet
controller that complies with IEEE 802.3u 10/100/1000 Base-T is used as the control-
ler chip. The Ethernet port is a standard RJ-45 jack. Additionally, LED indicators are
provided on the front of the device to indicate the system’s Link/Speed (off/green/
orange) and Active (green) status.
2.4 Power Connector
UNO-2372G-J1 features a Phoenix connector that is compatible with 10 ~ 36 VDC
external power. The inclusion of reversed wiring protection means that reversed wir-
ing of the ground and power lines will not damage the system components. (Refer to
Appendix A.3 for more information.)
2.5 USB Connector
The USB interface supports plug-and-play functionality, which enables users to con-
nect or disconnect a device without turning off the computer. The UNO-2372G-J1
also features four USB connectors that support plug-and-play and hot-swapping
functionality for external devices. The USB interface can be enabled/disabled in the
BIOS menu. Furthermore, the UNO-2372G-J1 also features four USB ports that com-
ply with USB EHCI, Rev. 3.0, specifications. (Refer to Appendix A.5 for pin assign-
ments.)
2.6 RTC Battery
The UNO-2372G-J1 is equipped with an RTC battery to ensure that the system clock
and BIOS settings are retained after power disconnections.
Type: BR2032
Output Voltage: 3 VDC
2.7 Power Button/Power Management
Press the “PWR” button to power on/off the UNO-2372G-J1 (ATX type). The system
can be configured to AT mode by adjusting the onboard switch to automatically turn
the system on when there is power input. (Refer to Appendix A.2 for more informa-
tion.)
2.8 Reset Button
Press the “Reset” button to activate the hardware reset function.

2.9 PCI Express Mini Card Socket
The UNO-2372G-J1 supports two full-size PCI Express mini card sockets. The loca-
tion MINI1 interface with PCIe and USB signal is provided to support various exten-
sion modules, such as Wi-Fi, 3G, and LTE modules, for diverse applications. The
UNO-2372G-J1 double-stack model also supports the integration of iDoor modules
(e.g., DI/O, COM, industrial fieldbus, etc.) via the MINI1 interface.
The MINI2 interface supports both PCIe and SATA signals and can automatically
detect the device type in order to provide the required support.
Note! In addition to the mini PCIe (MINI1) socket, the system features a micro
SIM slot (CN10 location) for supporting 3G/LTE function. However,
users are required to install a 3G/LTE mini PCIe module to enable this
functionality. The location of MINI1/ MINI2 can refer to Figure A.1.
