2.3 Unpacking Precautions
Some components on JUKI-C400’s are very sensitive
to static electric charges and can be damaged by a
sudden rush of power. To protect it from unintended
damage, be sure to follow these precautions:
ü Ground yourself to remove any static charge
before touching your JUKI-C400 SBC. You can do
it by using a grounded wrist strap at all times or
by frequently touching any conducting materials
that is connected to the ground.
ü Handle your JUKI-C400 SBC by its edges. Don’t
touch IC chips, leads or circuitry if not necessary.
ü Do not plug any connector or jumper while the
power is on.
2.4 Clear CMOS Setup
To clear the CMOS Setup (for example, if you have
forgotten the password, you should clear the CMOS
and then re-set the password), you have to close the
J5 (2-3) for about 3 seconds, then open it. This will
put the system back to normal operation mode.

Chapter 4 AMI BIOS Setup
4.1 Getting Start
This manual discusses AMI's Setup program built into
the ROM BIOS. The Setup program allows users to
modify the basic system configuration. This special
information is then stored in battery-backed RAM so
that it retains the Setup information when the power
is turned off.
4.2 Starting Setup
The AMI BIOS is immediately activated when you first
power on the computer.The BIOS reads the system
information contained in the CMOS and begins the
process of checking out the system and configuring it.
When it finishes, the BIOS will seek an operating
system on one of the disks and then launch and turn
control over to the operating system.
While the BIOS is in control, the Setup program can
be activated in one of two ways:
(1) By pressing <Del> immediately after switching the
system on
(2) By pressing the <Del>key when the following message
appears briefly at the bottom of the screen during the
post.
Press DEL to enter SETUP.
If the message disappears before you respond and
you still wish to enter Setup, restart the system to try
again by turning it OFF then ON or pressing the
30
"RESET" button on the system case. You may also
restart by simultaneously pressing <Ctrl>, <Alt>, and
<Delete> keys. If you do not press the keys at the
correct time and the system does not boot, an error
message will be displayed and you will again be asked
to...
PRESS F2 TO CONTINUE, DEL TO ENTER SETUP
4.3 Using Setup
In general, you use the arrow keys to highlight items,
press <Enter> to select, use the PageUp and
PageDown keys to change entries, press <F1> for
help and press <Esc> to quit.The following table
provides more detail about how to navigate in the
Setup program using the keyboard.

4.4 Getting Help
Press F1 to pop up a small help window that describes
the appropriate keys to use and the possible
selections for the highlighted item. To exit the Help
Window press <Esc> or the F1 key again.
If, after making and saving system changes with
Setup, you discover that your computer no longer is
able to boot, the AMI BIOS supports an override to
the CMOS settings which resets your system to its
defaults.
The best advice is to only alter settings which you
thoroughly understand. To this end, we strongly
recommend that you avoid making any changes to the
chipset defaults. These defaults have been carefully
chosen by both AMI and your systems manufacturer
to provide the absolute maximum performance and
reliability. Even a seemingly small change to the
chipset setup has the potential for causing you to use
the override.
32
4.5 Main Menu
Once you enter the AMIBIOS™ CMOS Setup Utility,
the Main Menu will appear on the screen. The Main
Menu allows you to select from several setup
functions and two exit choices. Use the arrow keys to
select among the items and press <Enter> to accept
and enter the sub-menu.
Note that a brief description of each highlighted
selection appears at the bottom of the screen.
The main menu includes the following main setup
categories. Recall that some systems may not include
all entries.

4.12 Hardware Monitor Setup
4.13 Change Supervisor Password
You can set either supervisor or user password, or
both of them. The differences between are:
Supervisor Password :
can enter and change the options of the setup menus.
50
User Password :
just can only enter but do not have the right to
change the options of the setup menus. When you
select this function, the following message will appear
at the center of the screen to assist you in creating a
password.
Enter Password :
Type the password, up to eight characters in length,
and press <Enter>. The password typed now will
clear any previously entered password from CMOS
memory. You will be asked to confirm the password.
Type the password again and press <Enter>. You
may also press <Esc> to abort the selection and not
enter a password.
Password Disabled:
To disable a password, just press <Enter> when you
are prompted to enter the password. A message will
confirm the password will be disabled. Once the
password is disabled, the system will boot and you
can enter Setup freely.
When a password has been enabled, you will be
prompted to enter it every time you try to enter Setup.
This prevents an unauthorized person from changing
any part of your system configuration.
Additionally, when a password is enabled, you can
also require the BIOS to request a password every
time your system is rebooted. This would prevent
unauthorized use of your computer.
51
You determine when the password is required within
the BIOS Features Setup Menu and its Security option
(see Section 3). If the Security option is set to
password will be required both at boot and at entry to
Setup. If set to “Setup”, prompting only occurs when
trying to enter Setup.
This chapter discusses the Setup program built into
the BIOS. which allows users to configure the system.
This configuration is then stored in battery-backed
CMOS RAM so that Setup information is retained
whilst the power is off.
52
Appendix A. Watchdog Timer
The Watchdog Timer is a device to ensure that standalone systems can
always recover from abnormal conditions that cause the system to crash.
These conditions may result from an external EMI or a software bug.
When the system stops working, hardware on the board will perform
hardware reset (cold boot) to bring the system back to a known state.
Three I/O ports control the operation of Watchdog Timer.
443 (hex) Write Set Watchdog Time period
443 (hex) Read Enable the Watchdog Timer.
043/843 (hex) Read Disable the Watchdog Timer.
Prior to enable the Watchdog Timer, user has to set the time-out period.
The resolution of the timer is 1 second and the range of the timer is from 1
sec to 255 sec. You need to send the time-out value to the I/O port – 443H,
and then enable it by reading data from the same I/O port – 443H. This will
activate the timer that will eventually time out and reset the CPU board. To
ensure that this reset condition won’t occur, the Watchdog Timer must be
periodically refreshed by reading the same I/O port 443H. This must be
done within the time-out period that is set by the software, please refer to
the example program. Finally, we have to disable the Watchdog timer by
reading the I/O port -- 843H or 043H. Otherwise the system could reset
unconditionally.
A tolerance of at least 5% must be maintained to avoid unknown routines
in the operating system (DOS), such as disk I/O that can be very timeconsuming. For example, if the time-out period has been set to 10 seconds,
the I/O port 443H must be read within 7 seconds.

How to use Wake-Up Function
JUKI-C400 provides two kinds of Wake-up function. This page
describes how to use Modem Wake-Up and LAN Wake-Up functions.
Wake-Up function only works with ATX power supply.
Wake-Up On Modem(Ring):
You must set the option Wake-Up On LAN/Ring of CMOS SETUP to
be enabled. ATX power supply will be switched on when there is a ring
signal detected on pin “RI” of serial port.
Wake-Up On LAN:
When your computer is in power-down status, you can see LAN
Link/Active LED is flashing. This status indicates that the LAN chip has
entered standby mode and waits for Wake-Up signal. You can use other
computers to wake up yours by sending ID to it.
ID: ID is the MAC address of your system LAN. Every LAN chip has a
factory-set ID, which you can find it from network information in
WINDOWS.
ID’s format is xxxxxxxxxxxx
Example ID: 009027388320
57
Appendix D. Digital I/O
One characteristic of digital circuit is its fast response to high or low
signal. This kind of response is highly needed for harsh and critical
industrial operating environment. That’s why we design 4-bit digital
inputs and 4-bit digital outputs on the JUKI-C400.
There are two kinds of signals (Input and Output) used by the Digital
I/O function. These signals are used to control external devices that
need On/Off circuit or TTL devices. When one of the signals has been
selected, The user can read or write data to the system through the
Digital I/O function.
A BIOS function call (INT 15H) is used to control the Watchdog Timer:
INT 15H :
AH – 6FH
Sub-function:
AL – 8 : Set the Digital port as INPUT
AL : Digital I/O input value
Example program:
MOV AX, 6F08H ;setting the Digital port is input
INT 15H ;
AL low byte = value
AH – 6FH
Sub-function:
AL – 9 : Set the Digital port as OUTPUT
BL : Digital I/O output value
Example program:
MOV AX, 6F09H ;setting the Digital port is output
MOV BL, 09H ;Digital value is 09H
INT 15H ;
Digital Output is 1001b
