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 sud­den 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, espe­cially 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.

PCA-6782 User Manual 10

1.10 Processor Installation

PCA-6782 series are equipped with soldered-down (BGA type) CPUs. no need for a
user to install a CPU.

1.11 CPU Cooler Installation

Only PCA-6782D needs to have a CPU cooler installed by user (P/N:
1960046526N001), PCA-6782N does NOT require this; it already has a passive
heat-sink assembled on the CPU card.

PCA-6782D users please follow the instructions below to install the CPU cooler
which is included in the package.

First locate the Atom D525 CPU then put the metal plate included in CPU cooler
package onto the solder side of the PCB with its four legs inserted into these four
mounting holes around the CPU, then attach the CPU cooler onto the CPU card by
fastening the four screws, one into each leg of the metal plate. Fasten the first screw
loosely, then loosely engage the second screw diagonally across from the first one,
then half fasten the third, and fourth screws. Finally snug all four screws completely,
following the same order.

Warning! Without a fan or heat sink, the CPU will overheat and cause damage to

both itself and the single board computer. If you are a D SKU user,
please install the CPU cooler (P/N: 1960046526N001) before booting up
the system and do NOT remove any on-board passive heat sinks; if you
are an N SKU user, please do NOT remove any on-board passive heat
sinks.
Improper CPU cooler installation may cause serious CPU die damage;
please follow the instructions above to install your CPU cooler.

PCA-6782 User Manual 12

2.1 Introduction

You can access most of the connectors from the top of the board while it is installed
in the chassis. If you have a number of cards installed or have a packed chassis, you
may need to partially remove the card to make all the connections.

You can configure your single board computer to match the needs of your application
by setting the jumpers. A jumper is a metal bridge that closes an electrical 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" (or turn ON) a jumper, you con­nect the pins with the clip. To "open" (or turn OFF) a jumper, you remove the clip.

Sometimes a jumper consists of a set of three pins, labeled 1, 2, and 3. In this case,
you connect either pins 1 and 2, or 2 and 3. A pair of needle-nose pliers may be use­ful when setting jumpers.

2.2 IDE Connector (IDE1)

Figure 2.1 PCA-6782 IDE1 location

You can attach up to two IDE (Integrated Drive Electronics) drives to the PCA-6782's
built-in controller. The primary connector can accommodate two drives.

Wire number 1 on the cable is red or blue and the other wires are gray. Connect one
end to connector IDE1 on the single board computer. Make sure that the red/blue
wire corresponds to pin 1 on the connector (in the upper right hand corner). See
Chapter 1 for help finding the connector.

Unlike floppy drives, IDE hard drives can connect in either position on the cable. If
you install two drives to a single connector, you will need to set one as the master
and the other as the slave. You do this by setting the jumpers on the drives. If you
use just one drive per connector, you should set each drive as the master. See the
documentation that came with your drive for more information.

Connect the first hard drive to the other end of the cable. Wire 1 on the cable should
also connect to pin 1 on the hard drive connector, which is labeled on the drive circuit
board. Check the documentation that came with the drive for more information.

The parallel port is normally used to connect the single board computer to a printer.
The PCA-6782 includes an onboard parallel port, accessed through a 26-pin flat­cable connector, LPT1. The card comes with an adapter cable which lets you use a
traditional DB-25 connector. The cable has a 26-pin connector on one end and a DB­25 connector on the other, mounted on a retaining bracket. The bracket installs at the
end of an empty slot in your chassis, giving you access to the connector.

The parallel port is designated as LPT1, and can be disabled or changed to LPT2 or
LPT3 in the system BIOS setup.

To install the bracket, find an empty slot in your chassis. Unscrew the plate that cov­ers the end of the slot. Screw in the bracket in place of the plate. Next, attach the flat­cable connector to LPT1 on the CPU card. Wire 1 of the cable is red or blue, and the
other wires are gray. Make sure that wire 1 corresponds to pin 1 of LPT1. Pin 1 is on
the upper right side of LPT1.

To facilitate the installation of the enhanced display drivers and utility software, read
the instructions in this chapter carefully. The drivers for the PCA-6782 are located on
the software installation CD. The driver in the folder of the driver CD will guide and
link you to the utilities and drivers under a Windows system. Updates are provided
via Service Packs from Microsoft*.

Before you begin, it is important to note that most display drivers need to have the
relevant software application already installed in the system prior to installing the
enhanced display drivers. In addition, many of the installation procedures assume
that you are familiar with both the relevant software applications and operating sys­tem commands. Review the relevant operating system commands and the pertinent
sections of your application software’s user manual before performing the installa­tion.

5.2 Introduction

Watchdog Timer

PCA-6782 User Manual 58

A.1 Watchdog Timer

The PCA-6782's watchdog timer can be used to monitor system software operation
and take corrective action if the software fails to function after a programmed period.
This section describes the operation of the watchdog timer and how to program it.

A.1.1 Watchdog Timer Overview

The watchdog timer is built into the super I/O controller W83627DHG-P. It provides
the following functions for user programming:

! Can be enabled and disabled by user program.
! Timer can be set from 1 to 255 seconds or 1 to 255 minutes.
! Generates an interrupt or resets signal if the software fails to reset the timer

after time-out.

A.1.2 Reset/ Interrupt Selection

The JWDT1 jumper is used to trigger system reset signal or to change GPIO14 state
in the event the watchdog timer is tripped. See Chapter 1 for detailed jumper settings.

Appendix A Programming the Watchdog Timer

A.1.3 Programming the Watchdog Timer

The I/O port address of the watchdog timer is 2E(hex) and 2F(hex).

2E (hex) is the address port. 2F(hex) is the data port.
You must first assign the address of the register by writing an address value into

address port 2E(hex), then write/read data to/from the assigned register through data
port 2F (hex).

PCA-6782 User Manual 84

C.1 Supported GPIO Register

Bellow are detailed description of the GPIO addresses and programming sample.

C.1.1 GPIO Registers

Extended Function Index Registers (EFIRs)

The EFIRs are write-only registers with port address 2Eh on PC/AT systems.

Extended Function Data Registers(EFDRs)

The EFDRs are read/write registers with port address 2Fh on PC/AT systems.

CR07 (Logical Device Number Register)

Set to ‘09’ to modify GPIO settings.

CRF0 (GP10-GP17 I/O selection register. Default 0xFF)

When set to '1', the respective GPIO port is programmed as an input port.
When set to '0', the respective GPIO port is programmed as an output port.

CRF1 (GP10-GP17 data register. Default 0x00)

If a port is programmed to be an output port, then its respective bit can be read/writ­ten.

If a port is programmed to be an input port, then its respective bit can only be read.

CRF2 (GP10-GP17 inversion register. Default 0x00)

When set to '1', the incoming/outgoing port value is inverted.

When set to '0', the incoming/outgoing port value is the same as in data register.
