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 merchandize
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.

Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from
damage.
To avoid electrical shock, always disconnect the power from your PC chassis
before you work on it. Don't touch any components on the CPU card or other
cards while the PC is on.
Disconnect power before making any configuration changes. The sudden rush
of power as you connect a jumper or install a card may damage sensitive elec-
tronic components.

UNO-430 User Manual 2
1.1 Introduction
Designed for use in harsh industrial environments, UNO-430 features all-around
IP69K/68-rated ingress protection and cable gland I/O connectors to provide a truly
watertight solution that can withstand the most demanding applications. The water-
proof enclosure features a front door for easy access and maintenance as well as a
cable gland that offers further ingress protection, reducing the need for waterproof
cables and wiring. This comprehensive protection also eliminates the need for a
waterproof cabinet, allowing customers to use the UNO-430 gateway as a stand-
alone data acquisition gateway. Moreover, with the provision of standard M.2 2230
Wi-Fi and M.2 3052/3042 5G/LTE sockets, the UNO-430 gateway offers expandable
wireless connectivity for remote communications and data transfers.
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-430. 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-430. 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 Jumper and Switch
2.2.1 Clear CMOS
Configure the UNO-430 to match the needs of your application by setting jumpers. 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.
UNO-430 mainboard contains a jumper that can erase CMOS data and reset the sys-
tem BIOS information. Normally this jumper should be set with pins 1-2 closed. If you
want to reset the CMOS data, set CMOS1 to 2-3 closed for just a few seconds, and
then move the jumper back to 1-2 closed. This procedure will reset the CMOS to its
default setting.
