Navman FISH 4500/4600 - Manual (Page 31)

6-7 Cleaning and maintenance
The FISH 4500/4600 screen is covered by a
proprietary anti-reflection coating. To avoid
damage, clean the screen only with a damp
cloth and mild detergent when dirty or covered
in sea salt. Avoid abrasive cleaners, petrol or
other solvents.
Cover or remove a transom-mounted trans-
ducer when repainting the hull. If painting over a
through hull transducer with antifouling paint, use
only one coat of paint. Remove the previous coat
of antifouling paint by sanding it lightly.
To optimize performance, avoid walking on or
jamming cables and connectors. Keep the trans-
ducer free of weed, paint and debris. Do not use
a high pressure water blast on a speed sensor
paddlewheel as it may damage the bearings.
When not in use, the FISH 4500/4600 can
be removed from the installation bracket and
stored in the Navman carry bag, or left on the
installation bracket and securely covered with
the sun cover supplied.
6-6 Systems of several instruments
Several Navman instruments can be connected
together to share data.
The FISH 4500/4600 is particularly suited to
work with the TRACKER 5500/5600 - Navman’s
color display GPS chartplotter with worldwide
coverage.
There are two ways of connecting instruments
together; NavBus or NMEA.
NavBus
NavBus is a Navman 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 au-
tomatically change in all instruments of the
same type.
• Each instrument can be assigned to a group
of instruments. Then, if the backlight setting
is changed in one group, it will automatically
change for the other instruments in that group.
However, the backlight setting will not change
for instruments in different groups.
• If an alarm sounds, mute it by clearing the
alarm on any instrument which can display
that alarm.
NMEA
NMEA is an industry standard for marine instru-
ment connections. Data sent by one instrument
over an NMEA line can be read and displayed
by another instrument that accepts NMEA
0183 Version 2. It is not as flexible as NavBus
as it requires dedicated connections between
instruments.
Please contact your Navman dealer for informa-
tion on Navman’s full range of NMEA enabled
instruments and connection options.
Repeater for depth, speed, water temperature and battery voltage.
Accepts NavBus or NMEA data inputs from other instruments.
