The
MK8
and
MK9
navigators have two independent possible interfaces.
A
Man
Over Board input and
an
NMEA
0183
version

talkerhstener interface.
an
Over
Board
A
push button
for
an
on/off
switch) (optional) can
be
connected between
the
Man
Over
Board
input
(D-SUB
pin
4)
and
the
REF
GND
(D
-
SUB
pin
1).
The installation
kit
includes
a
9
socket
D
-
SUB
connector mounted
with
all
the
necessary cabling. The
Man
Over Board
is
either
a
joint BLACK pair with one
wire marked with
an
embossment
or
a
joint GRAY pair with one wire marked
with
a
black stripe.
The
pair
should
be
connected to
a
push button that
is
normally
off
(not short
-
circuited). To enable the Man Over Board function
the
switch must be activated
for
at
least
2
seconds.
Please be aware,
that
the
unmarked
wire
of
this
pair
is
connected to
the
shield
of
the
navigator.
A
typical installation
is
shown
in

The standard marine interface
NMEA

version
2.0
is
used
for
comrnunica-
tion with other marine equipment like:
Radars, Plotters, Autopilots, Fish Finders etc.

There should be no problem
in
interfacing
to
other instruments. Version
2.0
of
the
NMEA
0183
interface
has
been changed in several ways compared
to
the
earlier
version 1.5. Same
of
the
changes to
the
hardware
should
be
mentioned
in
order
to
avoid problems.

The listener input
now
works
with
a
threshold of

It
is
still
an

The maximum drive voltage between
