ESD Precautions
Computer boards have integrated circuits sensitive to static electricity. To prevent chipsets
from electrostatic discharge damage, please take care of the following jobs with precautions:
Do not remove boards or integrated circuits from their anti-static packaging until you are
ready to install them.
Before holding the board or integrated circuit, touch an unpainted portion of the system
unit chassis for a few seconds. It discharges static electricity from your body.
Wear a wrist-grounding strap, available from most electronic component stores, when
handling boards and components.

®
TM
The CAPA830, a Capa board, supports Intel Atom D2550/N2800/N2600 processors. The
®
board integrates the Intel NM10 chipset and delivers outstanding system performance
through high-bandwidth interfaces, multiple I/O functions for interactive applications and
various embedded computing solutions.
There is one 204-pin unbuffered SO-DIMM socket for single channel DDR3 800/1066MHz
memory, maximum memory capacity up to 4GB (N2600 supports DDR3 800MHz up to 2GB
only). It also features two Gigabit/Fast Ethernet ports, one serial ATA channels for total one
Serial ATA hard drive at maximum transfer rate up to 300MB/sec, six USB 2.0 high speed
compliant, and built-in HD audio codec that can achieve the best stability and reliability for
industrial applications. Additionally, it provides you with unique embedded features, such as
two serial ports and 3.5” form factor that applies an extensive array of PC peripherals.
Moreover, the CAPA830 is in ZIO form factor which provides a flexible and functional design
for single board embedded systems. It is a solution for those who face limited expandability
from the use of conventional single board designs and has ability to extend I/O modules in a
flexible manner.

Jumper Settings
Jumper is a small component consisting of jumper clip and jumper pins. Install jumper clip on 2
jumper pins to close. And remove jumper clip from 2 jumper pins to open. Below illustration
shows how to set up jumper.
Properly configure jumper settings on the CAPA830 to meet your application purpose. Below
you can find a summary table of all jumpers and onboard default settings.
Note: Once the default jumper setting needs to be changed, please do it under
power-off condition.

lights up when the system is powered on.
External Speaker and Internal Buzzer
Pin 2, 4, 6 and 8 connect the case-mounted speaker unit or internal buzzer. While
connecting the CPU board to an internal buzzer, please set pin 2 and 4 closed; while
connecting to an external speaker, you need to set pins 2 and 4 opened and connect the
speaker cable to pin 8(+) and pin 2(-).
Power On/Off Button
Pin 9 and 10 connect the power button on front panel to the CPU board, which allows
users to turn on or off power supply.
System Reset Switch
Pin 11 and 12 connect the case-mounted reset switch that reboots your computer
without turning off the power switch. It is a better way to reboot your system for a longer
life of system power supply.
HDD Activity LED
This connection is linked to hard drive activity LED on the control panel. LED flashes
when HDD is being accessed. Pin 13 and 14 connect the hard disk drive to the front
panel HDD LED, pin 13 is assigned as cathode(-) and pin 14 is assigned as anode(+).

AMI BIOS Setup Utility
The AMI UEFI BIOS provides users with a built-in setup program to modify basic system
configuration. All configured parameters are stored in a flash chip to save the setup information
whenever the power is turned off. This chapter provides users with detailed description about
how to set up basic system configuration through the AMI BIOS setup utility.
4.1
Starting
To enter the setup screens, follow the steps below:
1.
2.
Turn on the computer and press the <Del> key immediately.
After you press the <Del> key, the main BIOS setup menu displays. You can access the
other setup screens from the main BIOS setup menu, such as the Advanced and Chipset
menus.
Note:
If your computer can not boot after making and saving system changes with Setup,
you can restore BIOS optimal defaults by setting JP3 (see section 2.3.3).
It is strongly recommended that you should avoid changing the chipset’s defaults. Both AMI
and your system manufacturer have carefully set up these defaults that provide the best
performance and reliability.
4.2
Navigation Keys
The BIOS setup/utility uses a key-based navigation system called hot keys. Most of the BIOS
setup utility hot keys can be used at any time during the setup navigation process. These keys
include <F1>, <F2>, <Enter>, <ESC>, <Arrow> keys, and so on.
Note: Some of the navigation keys differ from one screen to another.

F4
The <F4> key allows you to save any changes you have made and exit
Setup. Press the <F4> key to save your changes.
Esc
The <Esc> key allows you to discard any changes you have made and exit
the Setup. Press the <Esc> key to exit the setup without saving your
changes.
Enter
The <Enter> key allows you to display or change the setup option listed for a
particular setup item. The <Enter> key can also allow you to display the
setup sub- screens.
4.3

Watchdog Timer
About Watchdog Timer
Software stability is major issue in most application. Some embedded systems are not
watched by human for 24 hours. It is usually too slow to wait for someone to reboot when
computer hangs. The systems need to be able to reset automatically when things go wrong.
The watchdog timer gives us solution.
The watchdog timer is a counter that triggers a system reset when it counts down to zero from
a preset value. The software starts counter with an initial value and must reset it periodically. If
the counter ever reaches zero which means the software has crashed, the system will reboot.
How to Use Watchdog Timer
The I/O port base addresses of watchdog timer are 2E (hex) and 2F (hex). The 2E (hex) and
2F (hex) are address and data port respectively.
Assume that program A is put in a loop that must execute at least once every 10ms. Initialize
watchdog timer with a value bigger than 10ms. If the software has no problems; watchdog
timer will never expire because software will always restart the counter before it reaches zero.

Digital I/O
About Digital I/O
The onboard digital I/O has 8 bits (DI0~2 and DO0~4). In default, all pins are pulled high with
+3.3V level (according to main power). The BIOS default settings are 3 inputs and 5 outputs
where all of these pins are set to 1. Use these GPIO signals to control cash drawers and sense
warning signals from an Uninterrupted Power System (UPS), or perform store security control
