2.2 Unpacking Precautions
Some components of JUKI-511P SBC 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 JUKI-511P 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.
Handle your JUKI-511P SBC 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.
There is one 168-pin DIMM socket to accept 3.3V
non-buffered SDRAM.
The max. Memory size is 256MB.

triggered before the time-out period ends, otherwise it will
assume the program operation is abnormal and will issue a
reset signal to start again. The Watchdog Timer is disabled by
reading port 043/843H. For detail information about
