16-6 Systems of several instruments
Explorer R310
Repeater for depth, speed,
water temperature and battery
voltage. Accepts NavBus or
NMEA data inputs from other
instruments.
Explorer D210
Depth Repeater
Several Northstar instruments can be connected
together to share data. There are two ways
of connecting instruments together, NavBus
or NMEA.
NavBus
NavBus is a Northstar proprietary system that
allows systems of multiple instruments to be
built using a single set of 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 (see section 15-10). 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 Explorer 660
The Explorer 660 can:
Display wind speed and direction from an
optional Wind instrument, such as a Northstar
W310 or W315.
Receive data from an optional GPS or
GPS/DGPS source.
Send data to optional Northstar instruments,
for example to a repeater.
NMEA
NMEA is an industry standard, but is not as
flexible as NavBus as it requires dedicated
connections between instruments. The Explorer
660 can:
Receive and display wind data from an
optional compatible wind instrument.
Receive data from an optional compatible
GPS or GPS/DGPS source.
Note: To use the NMEA input, a Northstar
special fuel cable is required (see below).
Send GPS position and other navigation
data to an autopilot or other instrument.
An autopilot requires APB, APA and VTG
sentences (see section 15-10).
Connecting the Explorer 660 to other instruments
To set up the Explorer 660 for these options, see sections 15-4 and 15-10.
