Safety Precautions
Before getting started, please read the following important safety precautions.
1. User should not modify any unmentioned jumper setting without Axiomtek FAE’s instruction. Any modification without instruction might cause system to become damage
2. The tBOX311-820-FL does not come equipped with an operating system. An operating system must be loaded first before installing any software into the computer.
3. Be sure to ground yourself to prevent static charge when installing the internal components. Use a grounding wrist strap and place all electronic components in any static­shielded devices. Most electronic components are sensitive to static electrical charge.
4. Disconnect the power cord from the tBOX311-820-FL before making any installation. Be sure both the system and the external devices are turned OFF. Sudden surge of power could ruin sensitive components. Make sure the tBOX311­820-FL is properly grounded.
5. Make sure the voltage of the power source is correct before connecting the equipment to the power outlet.
6. Turn OFF the system power before cleaning. Clean the system using a cloth only. Do not spray any liquid cleaner directly onto the screen.
7. Do not leave this equipment in an uncontrolled environment where the storage temperature is below -40℃ or above 80℃.
It may damage the equipment.
8. Do not open the system’s back cover. If opening the cover for maintenance is a must, only a trained technician is allowed to do so. Integrated circuits on computer boards are sensitive to static electricity. To avoid damaging chips from electrostatic discharge, observe the following precautions:
Before handling a board or integrated circuit, touch an
unpainted portion of the system unit chassis for a few seconds. This will help to discharge any static electricity on your body.
When handling boards and components, wear a wrist-
grounding strap, available from most electronic component stores.

Introduction
v
Cleaning Tools:
Although many companies have created products to help improve the process of cleaning your computer and peripherals users can also use household items to clean their computers and peripherals. Below is a listing of items you may need or want to use while cleaning your computer or computer peripherals.
Keep in mind that some components in your computer may only be able to be cleaned using a product designed for cleaning that component, if this is the case it will be mentioned in the cleaning.
Cloth: A piece of cloth is the best tool to use when rubbing up
a component. Although paper towels or tissues can be used on most hardware as well, we still recommend you to rub it with a piece of cloth.
Water or rubbing alcohol: You may moisten a piece of cloth a
bit with some water or rubbing alcohol and rub it on the computer. Unknown solvents may be harmful to the plastics parts.
Vacuum cleaner: Absorb the dust, dirt, hair, cigarette particles,
and other particles out of a computer can be one of the best methods of cleaning a computer. Over time these items can restrict the airflow in a computer and cause circuitry to corrode.
Cotton swabs: Cotton swaps moistened with rubbing alcohol
or water are excellent tools for wiping hard to reach areas in your keyboard, mouse, and other locations.
Foam swabs: Whenever possible it is better to use lint free
swabs such as foam swabs.
NOTE: We strongly recommended that you should shut down
the system before you start to clean any single components.
Please follow the steps below:
1. Close all application programs
2. Close operating software
3. Turn off power switch
4. Remove all device
5. Pull out power cable
vi
Scrap Computer Recycling
If the computer equipments need the maintenance or are beyond repair, we strongly recommended that you should inform your Axiomtek distributor as soon as possible for the suitable solution. For the computers that are no longer useful or no longer working well, please contact your Axiomtek distributor for recycling and we will make the proper arrangement.

WATCHDOG TIMER
About Watchdog Timer
Software stability is major issue in most applications. 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. It can be set by programming its 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 the Watchdog Timer
Assembler Sample Code
;Enable WDT: mov dx,2Eh mov al,87h ;Un-lock super I/O out dx,al out dx,al
;Select Logic device: mov dx,2Eh mov al,07h out dx,al mov dx,2Fh mov al,08h out dx,al

;Disable WDT: mov dx,2Eh mov al,30h out dx,al mov dx,2Fh mov al, 00h ;Can be disable at ant time out dx,al
Note:
When N’s value is 00h, the time base is set second.
M = 00: Time-out Disable
01: Time-out occurs after 1 second 02: Time-out occurs after 2 seconds 03: Time-out occurs after 3 seconds FF: Time-out occurs after 255 seconds
Sample of Watchdog application
Assume there is program A which needs to maintain running in a system. The value of Watchdog Timer must be set bigger than the running time of program A. Then, after the running time of program A is finished, either to disable or to reset watchdog timer. When program A has problems to make system shut down, the system can be rebooted by Watchdog timer when the value of watchdog timer is countdowned to 0.

APPENDIX D
Power On Procedure
tBOX311-820-FL is an embedded system which is designed for vehicle, and supports both vehicle with +12V car battery or +24V car battery. The boot up requirement is quite different from normal embedded system. Please do follow the instruction in this section.
1 Introduction
Most of the times, car batteries will stay at 13.5V~15V (for 12V Mode), or at 27V~30V (for 24V Mode) while car engine is running, so specified above 13V or 26V power on will ensure that car engine is running and prevents a cold crank while car engine is started.
This cold crank will cause car battery voltage to drop to minimum 6V (at 12V mode) or more low, at this time,the most difficult task to provide a stable +12V output power to PC system to prevent PC system from cold boot.
In order to ensure the vehicle could provide a stable DC power, tBOX311-820-FL will detect the DC power from source is higher than the Start Voltage or not.
