NavBus is NAVMAN’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.
