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 purchase.
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 defective, 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 man-
ual, 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.

Declaration of Conformity
CE
This product has passed the CE test for environmental specifications when shielded cables are used for external wiring. We recommend the use of shielded cables. This kind of cable is available from Advantech. Please contact your local supplier for ordering information.
FCC Class A
Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environ­ment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Opera­tion of this equipment in a residential area is likely to cause harmful inter­ference in which case the user will be required to correct the interference at his own expense.
Technical Support and Assistance
Step 1. Visit the Advantech web site at www.advantech.com/support
where you can find the latest information about the product.
Step 2. Contact your distributor, sales representative, or Advantech's cus-
tomer service center for technical support if you need additional assistance. Please have the following information ready before you call:
- Product name and serial number
- Description of your peripheral attachments
- Description of your software (operating system, version, appli­cation software, etc.)
- A complete description of the problem
- The exact wording of any error messages

Safety Instructions
1. Read these safety instructions carefully.
2. Keep this user manual for later reference.
3. Disconnect this equipment from DC outlet before cleaning. Do not
use liquid or spray detergents for cleaning.
4. For pluggable equipment, the power outlet shall be installed near
the equipment and shall be easily accessible.
5. Keep this equipment away from humidity.
6. Put this equipment on a reliable surface during installation. Drop-
ping it or letting it fall could cause damage.
7. Make sure the voltage of the power source is correct before con-
necting the equipment to the power outlet.
8. Place the power cord such a way that people can not step on it. Do
not place anything over the power cord. The voltage and current rating of the cord should be greater than the voltage and current rat­ing marked on the product.
9. All cautions and warnings on the equipment should be noted.
10. If the equipment is not used for long time, disconnect it from the
power source to avoid being damaged by transient over-voltage.
11. When power core is connected, never open the equipment. For
safety reasons, the equipment should be opened only by qualified service personnel.
12. If any of the following situations arises, get the equipment checked
by service personnel:
A. The power cord or plug is damaged.
B. Liquid has penetrated into the equipment.
C. The equipment has been exposed to moisture.
D. The equipment does not work well or you cannot get it to work
according to user manual.
E. The equipment has been dropped and damaged.
F. The equipment has obvious signs of breakage.
13. CAUTION: The computer is provided with a battery-powered
real-time clock circuit. There is a danger of explosion if battery is incorrectly replaced. Replace only with same or equivalent type
v
recommended by the manufacture. Discard used batteries accord­ing to the manufacturer’s instructions.
14. This device complies with Part 15 of the FCC rules. Operation is
subject to the following two conditions: (1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including
interference that may cause undesired operation.
15. CAUTION:
your chassis whenever you work with the hardware. Do not make connections while the power is on. Sensitive electronic components can be damaged by sudden power surges.
16. CAUTION: Always ground yourself to remove any static charge
before touching the motherboard, backplane, or add-on cards. Mod­ern electronic devices are very sensitive to static electric charges. As a safety precaution, use a grounding wrist strap at all times. Place all electronic components on a static-dissipative surface or in a static-shielded bag when they are not in the chassis.
17. CAUTION: Any unverified component could cause unexpected
damage. To ensure the correct installation, please always use the components (ex. screws) provided with the accessory box.
Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from damage.
1. 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.
2. Disconnect power before making any configuration changes. The
sudden rush of power as you connect a jumper or install a card may damage sensitive electronic components.
Always completely disconnect the power cord from

2.3 RS-232/422/485 Interface (COM3~COM4)

The UNO-3074 offers two industrial RS-232/422/485 serial communica­tion interface their pin assignments. The default setting of COM3 and COM4 are RS­422/485. (Please refer to section 2.3.4 for how to determine RS-232 or RS-422/485)
2.3.1
Advantech UNO-3074 comes with 16C550 UARTs containing 16 bytes FIFOs.
2.3.2
In RS-422/485 mode, UNO-3074 automatically detects signals to match RS-422 or
ports: COM3 and COM4. Please refer to Appendix A.5 for

Automatic Data Flow Control Function for RS-485

In RS-485 mode, UNO-3074 automatically detects the direction of incom­ing data shaking signal RS-485 network cation can be maintained without
