3.2 SYSTEM CONFIGURATION
NOTE: See also Figure 3-2, System Configuration with Options.
The basic system configuration is as follows:
• 1 x Display and Control Unit LAZ 5100
• 1 x Connection Box
• 1 x Transducer
3.2.1 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 is made up 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 unit, working with different transducers on different
frequencies, see Technical Data.
When used with only one transducer ( see Figure 3-1 ), the display area shows the following:
• 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
With two channels, a vertical split display shows left half channel 2 information, 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).
