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.

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.

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

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.

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.
