TECHNICAL DESCRIPTION

3.2.2 Display and Control Unit
The Display and Control Unit will normally be installed on the bridge, either mounted
in a console or bracket mounted to the deckhead or bulkhead.
It consists of a display area and a keypad which is used to alter system parameters
and settings.
The unit can be a one or two channel version, working with different transducers on
different frequencies, see chapter 3.4 “Technical Data”.
The display area shows the following:
One channel (used with only one transducer)

Water depth

Range scale

Time and Date

Latitude and Longitude (if connected to a navigation system with a standard
NMEA 0183, version 2.0 interface)

Minimum and maximum depth alarm settings (if activated)

A trace of the sea bed

A colour bar representing the signal strength of the echoes
Two channels (used with two transducers)

vertical split display shows on the left half channel 2 information, on the right half
channel 1 information.

Instead of LAT/ LONG a second water depth indication appears.
A built-in ring memory continually stores system data, this allows the user to
recall data to the screen, or print out a hard copy of any or all events occurring
within the last 24 operating hours (if a printer is connected).
3.2.3 Transducer Connection Box
This will usually be installed near the transducer, to allow a defective transducer to be
replaced without having to replace the complete cabling to the Display and Control
Unit. The connection box must be made of metal.
3.2.4 Transducer
The transducer converts electrical energy to sound energy and transmits this towards
the sea bed. Sound energy returning from the sea bed, in the form of echoes, is
converted into electrical energy by the transducer and fed to the Display and Control
Unit for evaluation and presentation.
