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.

Declaration of Conformity
FCC Class B
Note: This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installa-
tion. This equipment generates, uses and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions, may cause harmful inter-
ference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful interfer-
ence to radio or television reception, which can be determined by turning the equip-
ment off and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
Warnings, Cautions and Notes
Warning! Warnings indicate conditions that, if left uncorrected, can cause per-
sonal injury!
Caution! Cautions are included to help you avoid damaging hardware or losing
data. e.g., there is a danger of a new battery exploding if it is incorrectly
installed. Do not attempt to recharge, force open, or heat the battery.
Replace the battery only with the same or equivalent type recom-
mended by the manufacturer.
Discard used batteries according to the manufacturer’s instructions.
Note! Notes provide optional additional information.

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.
Take care to avoid electrostatic discharge (ESD) before making any configura-
tion changes. Use a static-free workstation, grounding strap, or take other pre-
cautions. The ESD that may occur as you connect a jumper or install a card can
damage sensitive electronic components.

3.1.5 GPIO Test
3.1.5.1 ROM-5420 GPIO Default Setting
* GPIO1 & GPIO3 has been reserved for camera input in ROM-5420. You can use
the two GPIO ports if you do not need the camera feature.
#cd /sys/class/gpio
You can use “ls” to list all GPIO devices, and you should also see GPIO ports in
above table.
3.1.5.2 Example of Testing GPIO
A. Set gpio177 GPI (in)
#echo in > ./gpio177/direction
#cat ./gpio177/direction
in
B. Set gpio178 GPO (out)
#echo out > ./gpio178/direction
#cat ./gpio178/direction
out
C. Set gpio177 GPO value “0”
#echo 0 > ./gpio177/value
D. Get gpio178 value
Note! Please make sure parameter “seek” is equal to 25118 as indicated in
red in above codes. If you create the file to a wrong sector, that may
damage the system.
