PC EXTENSION INTERFACE PROTECTOR
APPLICATIONS IN EDUCATION
FIELD
PC is playing an important role in
industrial field because of high-speed
development, reliable, low-price, various
functions. Hardware interface
circuit and controlled software comple-
ment each other in Microcontrolled
system. Engineers in this field must
deeply understanding the skills of
hardware interface and software
designed that can function efficiently in
microcontrolled system.
In general laboratory, either in education
or academic field, tutors are
not willing to teach this section for the
following reasons
1. It will damage the PC for wrong
soldering in experiment circuit board.
2. Losing component parts or cause
damages by dismantling PC case.
3. It is time wasting to turn on/off if there
are mistakes in experiment, because
of the necessary load and save
operation.
4. Bread board experiment are not
accepted.
For solving above problems, simply plug
in PC EXTENSION INTERFACE
PROTECTOR PCF ACE-III which can
provide you functions as following
1. The cable line is long enough up to 75
cm between PC and PCFACE-III.
2. Conveniently four slot designed to
plug in/out the unit under test on
PCFACE-III.
3. No need to dismantle the case of PC.
4. Easy to test and measure messages
from PC according to pin indication on
slot.
5. Easy to detect shorted circuit
according to power indication. It can
prevent the malfunction of power.
6. PCFACE-III which is a Protector of
Mother Board type. Users can
turn on/off PCFACE-III instead of
turning on/ff the whole PC system.
It is convenience and time saving,
especially in testing. You will find
work efficiency that can be en-
hanced.
3. Interface Card manufacturer: To do
QC for Interface Card by using
interface slot.
There are a few problems which can
disturb your work or damage
your PC by using interface slot on PC.
1. Shorted circuit caused by soldering in
design or experiment interface.
2. For not knowing reasons, damage
main unit by using the ruined Interface
Card.
3. In Interface Card manufacturing,
harmful Interface cards causes
losses by doing QC for their prod-
ucts.
LEAP ELECTRONIC presents PCF ACE-III
which can prevent those problems for
you.
PCFACE-III FEA TURES.
1. Prevent damages for PC during
experiment.
2. Prevent damages during Interface
Card mending.
3. T est on PCFACE-III EXTENSION
INTERF ACE slots, you can
promptly choose the harmful one to
prevent the damages on the PC.
4. PCFACE-III which is a Protector of
Mother Board type. User can turn on/
off PCFACE-III instead of turning on/
ff the whole PC system. It is conve-
nience and time saving, especially in
testing. You will find
work efficiency that can be en-
hanced.
5. Prevent malfunction from short circuit
on the slot by power protection in
PCFACE-III.
6. Prevent damages on mother board or
Interface Card by message protection
sending to the extension slot.
PCFACE-III SPOTLIGHTS
*Plug in/out Interface Card by not turning
off PC
*All message cable and power have
block function
*Real signal extension system, ALL
messages can be testing
on extension slot.
*Four layer designed, no disorderly
message and with HIGH stability.
*Over current protecting indiction in four
LED.
7. Able to perform bread board experi-
ment by using the PCF ACE-III
slot pin diagram.
8. No hard state limited for interface
experiment.

Education authority can introduce public
printed textbook to perform I/O
interface experiment which listed as
following. LEAP ELECTRONIC also
provides I/O experiment card for the
experiment.
1. Assembly language programming
2. Implementing standard program
structures in 825x assembly
language
3. Strings, procedures and macros
4. System connections, timing and
troubleshooting
5. Interrupts and interrupt applications
6. Digital interfacing
7. Analog interfacing and industrial
control
8. DMA, DRAMs, cache memories,
coprocessors and EDA tools
9. C, a high-level language for system
programming
10.Microcomputer system peripherals
11.Data communications and networks
12.The experiment of 8253/8254/8255
APPLICA TIONS IN INDUSTRIAL
FIELD
PC EXTENSION INTERFACE PROTECTOR
are widely applicated
in industrial field.Usually, it can be used
in three occasions as following.
1. R&D dept: for I/O designing or
experiment.
2. Maintenance: To maintain all kinds of
Interface Card.
