1. INTRODUCTION
SYSTEM SUMMARY.
DL850 is a navigation, 2 Axis Doppler Log with a large, high resolution graphic LCD. An auxiliary,
shallow water echo sounder function is included. The display graphics is continuously shown on the
LCD along with complete navigation details. All IMO requirements are met or exceeded. Comprehen-
sive interfaces are available including NMEA0183 input and output.
TRANSDUCER AND TRANSCEIVER.
DL850 transducer consists of a head with a total of 5 hydro-acoustic elements:
4 off 540 kHz elements for the 2 axis log function and 1 off 270kHz element for the auxiliary echo
sounder function. The Transducer is connected to a Transceiver electronics cabinet located within
30 m of the transducer. The connection from the transceiver to the operator unit is via a serial RS-422
data link and may be up to 300 m.
Transceiver power supply options are 230V AC or 24V DC. The power consumption is appx.. 80 Watts
at 115/230V AC or 60 Watts at 24V DC.
OPERATOR UNIT.
The operator unit contains a graphic dot-matrix color TFT LCD display and a keyboard with xed keys,
soft-keys and a rotating encoder. The function of each softkey button depends on the active screen, and
the buttons are labelled on the lower rim of the LCD. The display is backlit, and backlight intensity may
be adjusted by the user. Various user-selectable information layouts, adapted to typical operational situ-
ations, may be displayed continuously on the LCD screen. The operator unit is normally ush mounted.
Operator Unit power supply options are 230V AC or 24V DC. The power consumption is appx. 70
Watts at 115/230V AC or 50 Watts at 24V DC.
Data Entry.
Several screens may be selected to enter various settings and calibration parameters. Each screen has
one or more softkey button menus, selectable with the leftmost “Menu” Softkey.
Screens 1 through 3 are primary operation screens with appropriate operator controls. Screens 4
through 6 are calibration setup and system supervision screens.
The various screens will be described in detail later.
The following pages illustrate the main DL850 operating facilities and comprise a Quick Operation Guide
including a System Conguration diagram.

INTERFACING.
The DL850 has various interface possibilities.
Outputs.
3 Log Outputs 100/200/400 Pulses per nautical Mile.
3 Analogue Outputs 0 - 10 V or 4 - 20 mA.
NMEA0183 Interface Output of Speed and Depth Information
External Alarm Relay Output.
Inputs
NMEA0183 Interface Input of Position, Heading, Depth, UTC.
“Rate of turn” analogue input. (OPTION)
Alarms.
High and low speed alarms may be selected from the menus. A potential free relay contact is provided
in DL850 for interface to external alarm systems.

2. OPERATION
When the installation is complete, and power is connected to the Operator Unit, the system is switched
on by pressing any button. The unit is switched off by pressing the “SYSTEM off” soft key button on
Screen 2.
PARAMETER ENTRY
The xed function buttons and the soft key buttons of the various screens along with the rotating
encoder, facilitates entry of parameters, setpoints and other data. The following ow chart illustrates the
procedure for changing settings and entering data. The various screens are shown in detail in the Opera-
tion Section.
Fig. 2.1 Setting and Parameter Entry Flowchart
Example of parameter entry.
Let us say you want to enter a value of 15 kts. for the High Speed Alarm.
Press a High Speed Alarm Soft Key, e.g. in Screen Pilot, Menu 1, and keep it pressed while you turn
the encoder until you reach 15 kts, let go of the encoder and release the High Speed Alarm button.
Buttons with less than 6 possible states or values can be operated without using the encoder at all.

2. Operation
When the installation is complete, and power is connected to the Operator Unit, the system
is switched on by pressing any button. The unit is switched off by pressing the “SYSTEM
off” soft key button on Screen 2.
Parameter entry
The fixed function buttons and the soft key buttons of the various screens along with the
rotating encoder, facilitates entry of parameters, setpoints and other data. The following
flow chart illustrates the procedure for changing settings and entering data. The various
screens are shown in detail in the Operation Section.

OPERATION SCREENS
Each of the operation screens contains a graphic picture and one or more Menu sets congured on the 6
soft key buttons. The various screens are selected by keeping the SCREEN SELECT button pressed and
rotating the encoder in either direction. Turning the encoder clockwise cycle the screens in the sequence
1 to 7, and counter clockwise rotation cycles the screens in the sequence 7 - 1. Screens no. 1 - 3, covering
the primary functions, may also be cycled by repeatedly pressing the SCREEN SELECT button.
The screen layouts are outlined in the following screens. The various Menus and Soft Key button functions
are described with each screen.
