SKIPPER Electronics AS DL850 270 kHz Operation and Installation
Important: During installation, DO NOT CUT THE TRANSDUCER CABLE.
The transducer, transducer cable and transceiver cabinet are all “balanced parts”. Therefore
cutting the cable may deteriorate performance and will also void the warranty.

1. Introduction
System Summary
The system is a navigation, 2 axis (transversal and longitudinal) Doppler speed log with a large
LCD. The display graphics is continuously shown on the LCD along with available navigation
details. Comprehensive interfaces are available including IEC 61162-1:2007(E) (NMEA 0183) input
and output. All IMO (International Maritime Organization) requirements for speed logs are met or
exceeded.
Sensor (Transducer) and Transceiver
The Doppler sensor consists of a head with hydro-acoustic elements. Two different versions of the
sensor head (270 kHz and 540 kHz) exist, both with 2 axis log function. The 540 kHz, has in addition,
one extra element for the auxiliary echo sounder option. The sensor is connected to a transceiver
cabinet located within 40 m of the sensor.
The connection from the transceiver cabinet to the operator unit is via a serial RS-422 data link and
may be up to 1000 m. Transceiver and operator unit power supply options are 115/230 V AC or 24 V
DC. The power consumption for the transceiver unit is app. 80 Watt at 115/230 V AC or 60 Watt at 24
V DC.

Operator Unit
The operator unit contains a graphic LCD display and a keyboard with fixed keys, softkeys 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 back lit, and back light intensity may be adjusted
by the user. Various user-selectable information layouts adapted to typical operational situations,
may be displayed continuously on the LCD. The operator unit can be flush mounted, wall mounted
or bracket mounted. Operator unit power supply options are 115/230 V AC or 24 V DC. The power
consumption is app. 70 Watt at 115/230 V AC or 50 Watt at 24 V DC.
Interfacing
The display unit has various interface possibilities.
Outputs
• 3 log outputs 10/100/200/400/1000 pulses per nautical mile.
• 2 outputs also gives speed direction.
• 3 analogue outputs 0 - 10 V or 4 - 20 mA.
• IEC 61162-1:2007(E) (NMEA 0183) interface output of speed/distance, temperature, alarm and
depth information.
• Functional alarm relay.
• Power failure alarm.
• Speed limit alarm.
• External VGA monitor.
Inputs
• IEC 61162-1:2007(E) (NMEA 0183) interface input for alarm, position, rate of turn, heading and
UTC (Coordinated Universal Time).
• External alarm reset.
Alarms
High and low speed alarms may be selected from the menus (screen pilot, menu 1). Alarms are
provided on both a potential free relay contact and as NMEA messages. Both ways can be used for
interface to external alarm systems. An optocoupler output is used as a separate output for power
failure alarm.

2. Operation
When the installation is complete, and power is connected to the operator unit, the system is switched
on/off by a power switch inside the cabinet. The unit can also be switched off by pressing the system
OFF softkey button.
Note: The unit is still energized. Do not perform any connections before switching off the mains
on the terminal PCB inside the cabinet.
Parameter entry
The fixed function buttons and the softkey buttons along with the rotating encoder, facilitates entry of
parameters and other data. The following flowchart illustrates the procedure for changing settings. The
various screens are shown in detail in the operation section.
Fig. 2.1 Setting and Parameter Entry Flowchart
Example of parameter entry
Suppose you want to enter a value of 15 knots for the high speed alarm. Press the SPD ALARM
softkey in screen pilot, menu 1, and keep it pressed while you turn the encoder until you reach 15 knots.
Release the encoder and release the SPD ALARM softkey.

Primary Screens
Each of the operation screens contains a graphic picture and one or more menu sets configured on
the 6 softkey buttons. The three first screens are covering the primary functions. Manoeuvring within
these screens are easily done by pressing the screen select button.
The various screens can also be selected by keeping the screen select button pressed and rotating the
encoder in either direction. Turning the encoder clockwise cycle the screens as shown in figure below,
and counter clockwise rotation cycles the screens in the opposite direction.
The screen layouts are outlined in the following pages. The various menus and softkey functions are
