Considerations
The
dual
serial
network
processor
module
contains
two jumpers
J-4 and
J-5
see
Figure
2-12
which
determine
whether
the ports
are
configured
for
nonreturn
to
zero
NRZ
or nonreturn
to
zero
inverted
NRZI
The
factory-configured
default
jumper
setting
is
for
NRZ
To
configure
for
NRZI
mode
on
each
port
the
jumper must
connect
pins
and
of the respective
jumper
locations
J-4 configures
serial
port
and
J-5
configures
serial
port
For
NRZ
only
the
jumpers
can
connect
pins
and
or
be removed
If
the
network
processor
module
is
operating
as
DTE
in
NRZI
mode
the
sense
of the dte-invert
timing
command
has
to
be manually changed
For
instance
if
the
command
no
dte-invert-timing
was
configured
then
dte-invert-timing
must
be
configured
Note
In the future
the
jumper
functions
will
be
incorporated
into
the system
configuration
software
soit
will
not be necessary
to
manually
set
jumpers
or use
the
dteinvert-timing
command
To
set
the
jumpers
for
NRZI
move
the
jumpers
to
the
position
shown
in
Figure
2-13
using
the
orientation
shown
in
