Northstar
FISH 457/467
Installation and Operation Manual
52
NavBus is Northstar’s system for connecting
instruments together to interchange data
and share transducers. When instruments are
connected by NavBus:
If the units, alarms or calibration are changed
in one instrument, then the values will
automatically change in all other instruments
of the same type.
Each instrument can be assigned to a group
of instruments. If the backlight is changed in
an instrument in group 1, 2, 3 or 4 then the
backlight will automatically change in the
other instruments in the same group.
If the backlight is changed in an instrument
in group 0 then no other instruments are
affected.
If an alarm sounds, mute it by clearing the
alarm on any instrument which can display
that alarm.
NavBus and the 457/467
The 457/467 can:
Display wind speed and direction from an
optional Northstar Wind instrument
Receive data from an optional Northstar VHF
radio (with NavBus functionality). The 457/467
can display:
Baro
: barometric pressure
Baro history
: barometer history
Weather
: a predication, based on changes in
barometric pressure
Fish forecaster
: a prediction based on
changes in barometric pressure
9-8 Installation: Other NavBus instruments
Send data to optional Northstar instruments,
for example to a repeater.
•
Receive and display GPS speed from a GPS
receiver

9-9 Installation: Other NMEA instruments
NMEA is an industry standard for interconnecting
instruments. It is not as flexible or as easy to
install as NavBus.
The 457/467 can send depth, speed and
temperature to other instruments.
During setup to send NMEA data to other
instruments, set
NMEA out
to
and specify
the
NMEA data
to send (see section 8-7).
