0.6 STATIC ELECTRICITY PRECAUTIONS
Before removing the board from its anti-static bag, read this section about static electricity precautions.
Static electricity is a constant danger to computer systems. The charge that can build up in your body
may be more than sufficient to damage integrated circuits on any PC board. It is, therefore, important to
observe basic precautions whenever you use or handle computer components. Although areas with
humid climates are much less prone to static build-up, it is always best to safeguard against accidents
that may result in expensive repairs. The following measures should be sufficient to protect your
equipment from static discharge:
„
Touch a grounded metal object to discharge the static electricity in your body (or ideally, wear a
grounded wrist strap).
„
When unpacking and handling the board or other system components, place all materials on an
anti-static surface.
„
Be careful not to touch the components on the board, especially the “golden finger” connectors on
the bottom of the board.

2.2 CPU INSTALLATION
The AR-B1892 embedded board supports a mPGA478MT processor socket for Intel® Core Duo or Core
solo processors.
The processor socket comes with a screw to secure the processor. As shown in the left picture below,
loosen the screw first before inserting the processor. Place the processor into the socket by making sure
the notch on the corner of the CPU corresponds with the notch on the inside of the socket. Once the
processor has slide into the socket, fasten the screw. Refer to the figures below.
After you have installed the processor into the socket, check if the jumpers for the CPU type and speed are
correct.

4. WATCHDOG TIMER CONFIGURATION
The WDT(Watch Dog Timer)is used to generate a variety of output signals after a user programmable count.
The WDT is suitable for use in the prevention of system lock-up, such as when software becomes trapped in
a deadlock. Under these sort of circumstances, the timer will count to zero and the selected outputs will be
driven. Under normal circumstance, the user will restart the WDT at regular intervals before the timer counts
to zero.
4.1 WATCHDOG TIMER SETTING
The watchdog timer is a circuit that maybe be used from your program software to detect crash or hang up.
The Watchdog timer is automatically disabled after reset. Once you enabled the watchdog timer, your
program should trigger the watchdog timer every time before it times out. After you trigger the watchdog
timer, the timer will be set to zero and start to count again. If your program fails to trigger the watchdog timer
before times out, it will generate a reset pulse to reset the system.
Users could test watchdog function under ‘Debug’ program as follows:
C:>debug
- o 2e 87
- o 2e 01
- o 2e 55
- o 2e 55
- o 2e 07
