4-6 Systems of several instruments
Several Navman instruments can be connected
together to share data, either by using NavBus
or NMEA.
NavBus
NavBus is a Navman proprietary system that is
high speed and allows a wide range of data to
be shared by the instruments.
When instruments are connected by NavBus:
•
Data from a sensor connected to one
instrument is available to all instruments.
•
If the units, alarms or calibration are
changed in one instrument, then the values
will automatically change in all instruments
of the same type.
•
Each instrument can be assigned to a group
of instruments by setting a group number
between 0 and 4. Then, if the backlight
is changed in an instrument in groups 1,
2, 3 or 4, it will automatically change in
all the other instruments in that group.

However, changing the backlight setting in
an instrument in group 0 will not affect any
other instrument.
To assign the FUEL 3100 or DIESEL 3200 to
a group, set GrouP in the LAmP menu
(see section 3-3).
•
If an alarm sounds, mute it by clearing the
alarm on any instrument which can display
that alarm.
•
NavBus junction boxes simplify wiring.
For more information, refer to the NavBus
Installation and Operation Manual.
NMEA
NMEA is an industry standard for marine
instrument connections. The FUEL 3100 and
DIESEL 3200:
•
Can read speed data (RMC) from a
compatible NMEA GPS instrument (see
section 3-6)
•
Transmit PTTKV, VHW, XDR, VLW .
