I/O Address Selection
Most
peripheral
devices
and
interface
cards
are
controlled
by
your
PC’s
I/O
ports.
These
devices
and
cards
should
be
placed
in
an
appropriate
I/O
space
so
that
there
will
be
no
conflicts
between
them
and
the
PCL-813.
Keep
in
mind
that
the
PCL-813
uses
16
consecutive
address
locations
in
your
PC’s
I/O
space.
The
following
table
provides
an
I/O
port
address
map
for
your
reference.
This
will
assist
in
locating
appropriate
addresses
for
your
other
peripheral
devices
and
interface
cards.
I/O
port
base
addresses
are
selected
from
the
6-position
DIP
switch
SW1
on-board
the
PCL-813.
The
valid
addresses
are
000
to
3F0
(hexadecimal).
The
factory
default
base
address
setting
is
220.
From
time
to
time,
you
may
find
that
you
will
have
to
use
some
of
these
spaces
for
other
devices.
If
this
is
the
case,
then
you
can
change
the
address
according
