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 free of charge during the warranty period. For out-of-
warranty repairs, customers are billed according to the cost of replacement materials,
service time and freight. Please consult your dealer for more details.
If you believe your product is defective, follow the steps outlined below.
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 messages displayed onscreen 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 authori-
zation (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 photograph of your sales
receipt) into a shippable container. Products returned without a proof of pur-
chase date are not eligible for warranty service.
5. Write the RMA number clearly on the outside of the package and ship the pack-
age prepaid to your dealer.

Initial Inspection
Before setting up the system, check that the items listed below are included and in
good condition. If any item does not accord with the list, contact your dealer immedi-
ately.
1 x ITA-5231 series industrial computer
1 x ITA-5231 accessory box
1 x Warranty card
If any of these items are missing or damaged, contact your distributor or sales
representative immediately. We have carefully inspected the ITA-5231 mechanically
and electrically before shipment. It should be free of marks and scratches and in per-
fect working order upon receipt. As you unpack the ITA-5231, check it for signs of
shipping damage (for example, box damage, scratches, dents). If it is damaged or
fails to meet the specifications, notify our service department or your local sales rep-
resentative immediately. Also, please notify the carrier. Retain the shipping carton

Safety Instructions
1. Read these safety instructions carefully.
2. Retain this user manual for future reference.
3. Disconnect the equipment from any power outlet before cleaning. Use only a
damp cloth for cleaning. Do not use liquid or spray detergents.
4. For pluggable equipment, the power outlet socket must be located near the
equipment and easily accessible.
5. Protect the equipment from humidity.
6. Place the equipment on a reliable surface during installation. Dropping or letting
it fall may cause damage.
7. The openings on the enclosure are for air convection. Protect the equipment
from overheating. Do not cover the openings.
8. Ensure that the voltage of the power source is correct before connecting the
equipment to a power outlet.
9. Position the power cord away from high-traffic areas. Do not place anything over
the power cord.
10. All cautions and warnings on the equipment should be noted.
11. If the equipment is not used for a long time, disconnect it from the power source
to avoid damage from transient overvoltage.
12. Never pour liquid into an opening. This may cause fire or electrical shock.
13. Never open the equipment. For safety reasons, the equipment should be
opened only by qualified service personnel.
14. If one of the following occurs, have the equipment checked by service person-
nel:
The power cord or plug is damaged.
Liquid has penetrated the equipment.
The equipment has been exposed to moisture.
The equipment is malfunctioning, or does not operate according to the user
manual.
The equipment has been dropped and damaged.
The equipment shows obvious signs of breakage.

v ITA-5231 User Manual
15. Do not leave the equipment in an environment with a storage temperature of
below -40 °C (-104 °F) or above 55 °C (131 °F) as this may cause damage. The
equipment should be kept in a controlled environment.
16. CAUTION: The battery is at risk of exploding if incorrectly installed. Do not
attempt to recharge, force open, or heat the battery. Replace only with the same
or equivalent type recommended by the manufacturer. Discard used batteries
according to the manufacturer’s instructions.
In accordance with IEC 704-1:1982 specifications, the sound pressure level at the
operator's position does not exceed 70 dB (A).
DISCLAIMER: These instructions are provided according to the IEC 704-1 specifica-
tions. Advantech disclaims all responsibility for the accuracy of any statements con-
tained herein.
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 the PC chassis
before manual handling. Do not touch any components on the CPU card or
other cards while the PC is powered on.
Disconnect the power before making any configuration changes. A sudden rush
of power after connecting a jumper or installing a card may damage sensitive
electronic components.
Battery Information

2.1 Introduction
The following sections show the internal jumper settings and external connector pin
assignments for system configuration according to applications.
2.2 Jumpers and Connectors
2.2.1 Jumper Description
ITA-5231 can be configured for specific applications 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, remove the clip. Some jumpers may have three pins,
labelled 1, 2, and 3. For these jumpers, connect either Pins 1 and 2, or Pins 2 and 3.
Open Closed 2-3 Closed
The jumper settings are schematically depicted in this manual as shown below.
Open Closed 2-3 Closed
A pair of needle-nose pliers may be helpful when working with jumpers. If you have
concerns about the best hardware configuration for your application, contact your
local distributor or sales representative before making any changes. For most con-
nection, only a standard cable is required.
