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.

1.4 Safety Precautions
The following sections tell how to make each connection. In most cases, you will
simply need to connect a standard cable.
Warning! Always disconnect the power cord from your chassis whenever you are
working on it. Do not connect while the power is on. A sudden rush of
power can damage sensitive electronic components. Only experienced
electronics personnel should open the chassis.
Caution! Always ground yourself to remove any static electric charge before
touching UNO-3285C. 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.

2.1 Introduction
The following figures show the interfaces of UNO-3285C and detailed information for
each peripheral.
Figure 2.1 Front View
2.2 Serial Interface (COM1/COM2)
UNO-3285C offers two standard RS-232/422/485 serial communication interface
ports:
The IRQ and I/O address of serial ports are listed as below.
COM1 (Pin header CN3)
COM2 (Pin header CN4)

Chapter 2 Hardware Functionality
2.2.1 RS-232/422/485 Interface (COM1 & COM2)
UNO-3285C offers two serial communication interface port.
SW1 for COM1(RS-232/422/485) switch
SW2 for RS485/422 receiver termination setting
SW3 for COM2(RS-232/422/485) switch
The COM ports default setting is RS422/485. It can also be switched to RS232 mode
manually.
In RS-422/485 mode, the UNO-3285C automatically detects signals to match RS-
422 or RS-485 networks.
In RS-485 mode, the UNO-3285C automatically detects the direction of incoming
data and switches its transmission direction accordingly. So no handshaking signal
(e.g. RTS signal) is necessary. This lets you conveniently build an RS-485 network
with just two wires. More importantly, application software previously written for half
duplex RS-232 environments can be maintained without modification.
