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).
