Removing the display unit
The display unit can be removed after each
use for protection against the environment or
security reasons.
When removing the display unit, ensure t hat
the plugs left in the boat are not exp osed to
the elements. Push the attached dust cover s
over the exposed ends of the plugs. Keep the
display unit in a dry clean place such as an
optional Navman carry bag.
Flush Mounting
1. Cut a hole in the bulkhead for the display
unit using the flush mount template.
2. Drill four holes for the mounting stu ds
using the flush mount template.
3. Screw the four studs into the brass inser ts
in the back of the display unit.
4. Sit the display unit in place and fit the
washers and nuts to the studs.
Bracket Mounting
1. Fix the mounting bracket onto the boat
using the three stainless steel screws. Do not
overtighten the screws, as the bracket may
not rotate.
2. Push the display unit onto the mounting
bracket and tighten it firmly using the k nob
on the mounting bracket.
3. Attach the cables.
6-4 Systems of several instrumen ts (4433 0nly)
Several Navman instruments can be conne cted
together to share data.
The FISH 4432/4433 is particularly suit ed
to work with the TRACKER 5430 (4.3”
greyscale)/5380 (3.8” color) - Navman’s GPS
chartplotters with worldwide cover age.
There are two ways of connecting inst ruments
together; NavBus or NMEA.
NavBus
NavBus is a Navman proprietary sys tem that
allows systems of multiple instrume nts to be
built using a single set of transducer s. When
instruments are connected by NavBus:
• If the units, alarms or calibratio n are
changed in one instrument, then the v alues
will automatically change in all instrum ents
of the same type.
• Each instrument can be assigned to
a group of instruments. Then, if the
backlight setting is changed in on e group,
it will automatically change for the othe r
instruments in that group. However, the
backlight setting will not chang e for
instruments in different group s.
• If an alarm sounds, mute it by clearing the
alarm on any instrument which can displ ay
that alarm.
NMEA
NMEA is an industry standard for m arine
instrument connections. Data sen t by one
instrument over an NMEA line can be read and
displayed by another instrument that acce pts
NMEA 0183 Version 2. It is not as flexible as
NavBus as it requires dedicated connect ions
between instruments.
Please contact your Navman dealer for
information on Navman’s full range of NME A
enabled instruments and connec tion options.
