Serial
Interface
Selection
The
serial
adapter
supports
different
interface
types
which
are
selected
by
placement
of
jumpers
on
the
card.
Each
port
has
three
rows
of
headers
(pins
sticking
up
from
the
card).
Each
row
is
labeled
with
a
port
number
and
an
interface
type
(RS
‐
232,
V.35,
RS
‐
422/485).
Place
jumpers
on
the
header
row
labeled
with
the
desired
interface
type.
The
interface
type
must
match
that
of
the
connected
communications
equipment.
Interface
selection
is
preset
at
the
factory
as
specified
by
the
ordering
code.
The
selection
may
be
changed
by
moving
the
jumpers
to
the
desired
header
row
as
described
above.
Use
pliers
to
remove
the
jumpers
from
the
current
position,
carefully
working
the
jumpers
loose
from
the
headers.
Take
care
to
not
damage
the
card
or
cause
injury.
Some
interface
types
require
a
conversion
cable
in
addition
to
a
specific
jumper
setting
to
provide
the
necessary
connector
type.
Refer
to
the
Serial
Pin
Assignments
section
for
more
details.
