SELECT NMEA
The
UltraNav II
sends data outthewhite wire onthe
powercableaccording
to
standards set
by
the NMEA
(National
Marine
Electronics
Association).
This
allows the UltraNav II to send
position,
depth,
and
navigation
information
to "listener"
units,
such as
charting instruments,
autopilots,
and
other
marine instruments. The UltraNav II uses
the
following
NMEA data
protocols:
NMEA 0180
and 0183. NMEA 0180
sends
steering
information
only.
It's useful
mainly
for
autopilots.
NMEA 0183
sends
depth, position,
steering, speed,
and more. In order to use this
feature,
the white wire on
the
power
cable
must be connected to the
NMEA data
input
on the other
instrument. See the installation section in the
front of this manual for
wiring
connection information.
The
UltraNav II also has the
capability
to receive differential
data from a beacon receiver.
This
gives
the unit much better
accuracy
thannormal. Howev-
er,
before
purchasing
and in-
stalling
a beacon
receiver,
make
certaintherearetransrnitters in
the area
you
wish to use.
Pres-
ently
the UltraNav II can use
the
Magnavox
MX-50R or
StarLink MRB-2A. Please note that the
UltraNav II doesn't send NMEA
0183 data when the
Magnavox
MX-50R
beacon receiver is activated.
NMEA SETUP
Once
you
connect the
wiring properly,
the
UltraNav II must be told which
NMEA
data format to use. Consult
the owner's manual of the other
equipmentto
seewhich format it needs. Then
setthe UltraNav II as follows:
First,
press
the MENU
key. Next, press
the
key
next to the "CHANGE G
PS
SETTINGS" label. Now
press
the
key
next to the "SELECT NMEA" label.
The screen shown above
appears.
The data format
currently
in use
shows at the
top
of the screen. Press the
key
next to the desired data
output.
Now
press
the CLEAR
key.
The
UltraNav II will return to the last used GPS
screen and send NMEA data
out the white wire on the
power
cable.
