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, other hardware and software used, etc.) Note DQ\WKLQJDEQRUPDODQG
list any onscreen messages you get when the problem RFFXUV
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 merchandise
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.
Before you begin installing your single board computer, please make sure that the

Certification and Safety Instructions
This device complies with the requirements in 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
This equipment has been tested and found to comply with the limits for a Class A dig-
ital device, pursuant to Part 15 of the FCC Rules. These limits are designed to pro-
vide 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. Opera-
tion of this device in a residential area is likely to cause harmful interference in which
case the user will be required to correct the interference at his/her own expense. The
user is advised that any equipment changes or modifications not expressly approved
by the party responsible for compliance would void the compliance to FCC regula-
tions and therefore, the user's authority to operate the equipment.
Caution! 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 recommended by the man-
ufacturer. Discard used batteries according to the manufacturer's
instructions.

PCA-6782 User Manual 2
1.1 Introduction
PCA-6782 is an Intel®Atom™ dual-core D525 / fanless N455 CPU based ISA-inter-
face half-size single board computer. With high performance Atom D525 dual-core
computing power, it is ideal for intense data or graphic processing applications; with
fanless Atom™ N455 CPU, it has ultra high reliability to resist heat, dust, vibration
and shock in any application environment.
PCA-6782 is designed with an Intel®Atom™ D525/N455 CPU and ICH8M I/O control
hub. The Atom™ D525 dual core CPU brings new generation computing capability
into the half-size SBC application field. Compact size, low power consumption (Total
power consumption ≤17.62 W) and dual-core parallel computing power and maxi-
mum 2 GB of DDR2 667 MHz memory capacity makes the PCA-6782D a powerful
small form-factor computer platform for modern industrial applications that require
high computing power. The fanless Atom™ N455 CPU (Total power consumption ≤
12.56 W) is ideal for data-acquisition, environment monitoring system and factory
automation that requires no air flow environments.
PCA-6782 has an integrated graphic core of Intel Embedded Gen3.5+ graphic tech-
nology with 224 MB shared memory. This feature makes PCA-6782 is capable of
handling complex and intense 2D/3D graphic processing without an add-on graphic
card; its VGA and LVDS dual video outputs also makes it suitable for applications
requiring dual display or digital panel display capabilities.
PCA-6782 is rich in I/O interfaces: it has three SATA ports (300 MB/sec) for main-
stream SSD (solid state disk), HDD, and ODD connections, one legacy IDE port for
the ODD connection. It also has a CF socket to support an economical, easy-to-
maintain SSD device. Additionally, the two serial ports (COM ports) can be used as
reliable legacy device control interfaces. Users can also purchase WKH COMSRUW
upgrade module (P/N: PCA-COM485-00A1E) to have four extra RS485 ports
with auto flow control capability.
1.2 Features
!Ultra low power (Total Power Consumption ≤12.56 W), fanless N455 CPU and
maximum 2 GB DDR2 667 memory (Only for N SKU)
!Dual-core D525 CPU and maximum 2 GB DDR2 667 memory (Only for D SKU)
!Intel® Embedded Gen3.5+ graphics core with 224 MB of shared memory with
VGA/LVDS dual video outputs (supporting clone and extension modes)
!Supports single-Gigabit Ethernet LANs with teaming capability
!Supports Embedded Software SUSI APIs and Utilities. (SUSI APIs: watchdog,
hardware monitor, brightness control, programmable GPIO, backlight On/Off;
Utilities: BIOS flash, eSOS (Requires BIOS Customization), system monitoring,
Flash Lock, software protection)

1.4 Jumpers and Connectors
Connectors on the PCA-6782 single board computer link it to external devices such
as hard disk drives and a keyboard. In addition, the board has a number of jumpers
used to configure your system for your application.
Below, Tables 1.1 and 1.2 list the jumper and connector functions. Later sections in
this chapter give instructions on setting jumpers. Chapter 2 gives instructions for con-
necting external devices to your single board computer.

Warning! Always completely disconnect the power cord from your chassis when-
ever you work with the hardware. Do not make connections while the
power is on. Sensitive electronic components can be damaged by sud-
den power surges. Only experienced electronics personnel should open
the PC chassis.
Caution! Always ground yourself to remove any static charge before touching the
single board computer. Modern electronic devices are very sensitive to
electrostatic discharges. 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.
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 recommended by the manufacturer.
Discard used batteries according to manufacturer's instructions.
Note! Before installing your PCA-6782 into a chassis, make sure that no com-
ponents on either side of the CPU card can touch any metal parts, espe-
cially the chassis wall and add-on card in the adjacent slot.

1.8 System Memory
The PCA-6782D has one SO-DIMM socket. PCA-6782 is ONLY compatible with
DDR2 memory modules that are assembled with x16 (16-bit) memory chips and NOT
compatible with those that are assembled with x8 (8-bit) memory chips. Using wrong
memory modules may cause system instability and unexpected behavior.
1.9 Memory Installation Procedures
1. See picture below to locate DIMMB1 200-pin SODIMM socket.
2. A memory module and expansion socket are keyed. The plastic bridge in the
socket must align with the notch in the module. The keyed bridge and notch
make sure a SODIMM cannot be installed going the wrong direction.
3. Insert the SODIMM module into the socket at a 30-45 degree angle. Make sure
the notch and the module are properly aligned.
Slowly push down the SODIMM toward the CPU card PCB until the clips at each
end of the expansion socket click into place.
