1.2 What You Have

Before you begin installing the product, please check the
following materials are included in the package:

• 1 ETX-DB-ATX ETX module baseboard

• 1 3.5” IDE flat cable (ATA-66, 44 pin 2.54mm pitch,

457mm)(32200-000052)

• 1 floppy cable (for 3.5” FDD only) (32200-000017)

• 1 serial port cable (for RS232) (32200-0000??)
If any of these items are missing or damaged, contact your

distributor or sales representative immediately.

2.2 Unpacking Precautions

Some components of ETX-DB-ATX 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 note
these precautions:

Ground yourself to remove any static charge before touching
the ETX-DB-ATX. 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.
Handle your ETX-DB-ATX by its edges. Don’t touch IC chips,
leads or circuitry if not necessary.
Do not plug any connector or jumper while the power is on.

2.3 LCD Vcc Voltage Selector

The LCD interface connector CN1, CN2, CN6 can provide 5V
or 3.3V power supply by selecting the JP4 to meet the different
LCD requirement.

1-2 5V

2-3 3.3V

2.4 Clear CMOS Setup

If you need to clear the CMOS Setup (for example, forgot the
password, you should clear the setup and then set the
password again.), you should close the JP6 about 3 seconds,
then open it again. Set back to normal operation mode by open
JP6.

2.5 WatchDog Timeout Active Selector

Reading I/O port 443H enables the WatchDog Timer. It should
be triggered before the time-out period ends, otherwise it will
assume the program operation is abnormal and will issue a
reset signal or an interrupt signal. The Watch-Dog Timer is
disabled by reading port 043/843H.detail information on
