1. Introduction
System Summary
The system is a navigation, 2 axes (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 300 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.

DL850 270 kHz Operation and Installation
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.
• 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.

Principal Functions
Doppler Log Principle
The Doppler log works on the principle of detecting Doppler frequency shifts, i.e the phenomena of
a perceived frequency being dependent on the relative speed of the emitting and receiving systems.
2v
∆f =
f
c
Observed frequency shift ∆f,
Emitted frequency f,
Measured velocity, v,
Speed of sound in water, c.
A short burst of a known frequency is emitted into the water, and the frequency of the received
echoes are measured. The difference between the emitted frequency and the received frequency
makes it possible to calculate the relative speed. If the reflecting body is the bottom, the measured
speed will be relative to ground. By measuring the reflections from the particles in a near water
layer, a relative water speed may be obtained.
Bottom Track Characteristics
DL850 will try to acquire a bottom track when the depth is between 2 and ca. 150 m, depending on
the bottom conditions. In this case, both bottom track and water track data will be acquired.
Water Track Characteristics
Water relative speed is measured at a depth of ca. 1 meter below transducer.
Docking Function - Option
Docking function is a feature for navigators which have a need of the transversal speed aft the ship.
Instead of installing a second sensor aft, (which will normally cause problems due to turbulence
under the sensor) the movement of the ship is calculated using the forward sensor and the gyro
compass’s rotation signal. Provided the ROT (Rate of Turn) signals fulfil the IMO standards (IMO
Resolution A.526 (13)) and the Doppler sensor is installed and operating correctly, the transversal
speed aft of the ship be calculated to the required accuracy of 0.2 kn.
The longer the vessel, the more accurate the requirement of the Doppler sensor. The accuracy
of the sensor can be increased by increasing the averaging time of the system, or the size of the
measurement sample (cell). The software will calculate the optimum averaging and cell size, based
on the requirement spec of the system and set this as the default value. It is likely the averaging can
be reduced to give a faster response as most systems have an actual performance better than the
requirements. During installation, parameters for the ship length at waterline and distance between
the bow and sensor must be entered into the log. These parameters are used for calculating the aft
speed.
Echo sounder option
With the echo sounder option active, the depth will be shown as a thick black line in the echo
sounder window, just showing the bottom contour. This depth is measured with the forward beam
(tilted) and can not be used for approved navigation as approved echo sounder function.

Non-volatile Parameter Memory
The system contains memory to maintain installation and user parameters like unit of measurement,
back light settings, etc. These parameters are kept in battery backed-up static RAM memory on
the I/O board, and are automatically restored on power up. If the user parameters have never been
set, default values are used. These values will be reset to default values when the “Master Reset”
procedure is performed.
Fixed Key Functions
Screen Select
The screen select button facilitates selection of one of the 7 screen and softkey layouts. The 3
primary operation screens may be cycled by repeatedly pressing the screen select button. Access
to the remaining screens is through encoder operation. The screens are cycled in an endless,
bidirectional loop, e.g. turning the encoder counter-clockwise, will “open” screen 7 after screen 1.
Backlight adjustment (brightness)
Backlight may be controlled by using the appropriate button and the encoder. Press the backlight
button and rotate the encoder until a satisfactory setting is obtained, then release the button. The
settings are maintained in the nonvolatile memory, and the last settings are restored on power up
Day/Night
Day/Night vision may be selected by pressing this button. These two modes differs by colour presentation,
which are optimized for different ambient light conditions.

Alarm buzzer
The local alarm buzzer may be disabled, but the external alarm relay will always operate. The only way
to disable the alarms completely, is to reduce the low speed alarm to zero and increase the high speed
alarm to maximum range.
Alarm acknowledgement
When any alarm is activated, the alarm may be acknowledged by pressing any button. Alarm relay
and audio alarm may be acknowledged by sending the “ACK” NMEA message from a alarm handling
system, or by operating a remote button that shorts the INHIB2 and INHIBREF lines on the combo
terminal board, (INHIB 2 = J100 pin 11, INHIBREF = J100 pin 9).
Clock and Calendar Settings
Manual clock and calendar adjustments are carried out in the screen status, menu 2. If a satellite
receiver giving UTC messages is connected to the NMEA input, the clock and calendar will be
automatically updated and manual adjustment is not available.
System On/Off
During normal daily operation, the system may be switched off from all primary screens. This
operation does not disconnect the system from the power supply, but all power consuming components
are switched off. The system may be switched on again by pressing any button.

Transducer Installation
Location
•
•
•
•
It is recommended to install the transducer in foreship.
Optimal system operation is achieved by fitting the transducer as deep as possible on the hull.
The transmitting surface of the transducer must be installed horizontal.
Do not mount transducers close to the bow thruster propeller outlets, or aft of other hull
installations (outlets, vents or other protruding details).
• It is necessary to select a part of the hull that is submerged under all load and speed conditions,
and to avoid positions where air is trapped in heavy weather.
• If a flat, horizontal section is not available for transducer fitting, the shipyard must construct a
suitable bed.
Protect the active element of the transducer and do not paint the surface.
Operator Unit Installation
Select a position to provide free view of the panel as well as easy access during operation and service.
The operator unit may be mounted flush in a panel, on a wall or directly onto a bulkhead. See appendix
1. Installation Drawings that shows the operator unit along with the main installation dimensions. If the
unit is to be flush mounted, the shown cut-out and recession depth dimensions must be observed.
Remember to leave room in front of the unit to open the door a full 90°.
Do not perform installation work with system power applied!
Cables are led through the appropriate cable glands as follows:
• The cable from the transceiver unit should normally occupy the left gland.
• The right gland is used for power supply connection.
• The centre ones are used for any interface signals connected.
Power supply may be either 115/230 V AC or 24 V DC. Power consumption is app. 50 W at 24 V DC
and app. 70 W at 115/230 V AC.
If the AC power system is 115 V, the system must be prepared for 115 V by re-connecting the
connectors J102, J103.
Fuses are shown in fig. 4.1 for 115/230 V AC and 24 V DC. These fuses are normal 5 x 20 mm slow
blow glass fuses.

NMEA interface
The NMEA output provides IEC 61162-1:2007(E) (NMEA 0183) format information for other
equipment with NMEA 0183 inputs. Default setting is 4800 Baud, 8 data bit, 1 stop bit, no parity. Several
messages may be selected on screen COM and the enabled messages are transmitted with maximum
interval of 1.8 seconds.
The NMEA inputs accept alarm, position, rate of turn, heading and UTC time messages from various
navigators and compasses.
One output can drive minimum of 10 standard NMEA 0183 inputs.
See section 5, Start-up and system adaption, for a complete list of transmitted and received messages.

6. Calibration procedure
Speed logs are calibrated in the factory to give reasonable results after installation, however installation
and hydrodynamics vary from vessel to vessel. It is therefore necessary to calibrate speed logs once in
place.
SKIPPER speed logs have two parameters that need to be corrected by calibration.
1. Angular sensor installation error (heading error).
2. Speed variations due to drag or mounting tilt.
1. Heading Error
Mounting error (heading error)
Forward
The heading error parameter corrects for an angular offset in mounting. This offset will result in a
rotation of the measurement axes. The resultant speed will be unaffected, but the longitudinal and
transversal components will be incorrect. An offset will result in the vessel typically showing too much
transversal speed, but may also result in speed calibration failing (i.e. initial calibration fails when
further points are added). This offset will show itself as an averaged drift on the calibration.
Reducing Heading errors. New generation sea valves can be manually adjusted to ensure the sensor
is correctly aligned. Alignment and heading offset are directly connected. To minimalise the offset, the
sensor should be mounted pointing ahead
• Tank mountings have ahead marks on both the tank and the sensor insert.
• Sea valves have either a mark on the top flange (DL850 540 retro fit system) or a flat mark on the
port side of the pole which when a flat object is placed against this, will point fore/aft (Figure 6.1).
2. Speed variations due to drag or mounting tilt.

DL850 270 kHz Operation and Installation
Every vessel will drag some water when it moves. This occurs over the
whole hull. As you move further from the hull, the effect of the ships
movement gets less. As the vessel moves at different speeds, the
hydrodynamics of the vessel may change. In most cases the drag is even
over the whole range of the vessel.
Speed logs that measure on the surface of the vessel (such as EML) are more affected by this factor
than sensors that measure remotely (Doppler). The calibration variation is usually less on remote
sensors.
As the calibration factors can vary at different vessel speeds, it is possible to calibrate several speeds.
It is typically necessary with only one high and one low speed. Speed logs with speed over ground can
be compared with GPS speed over ground in stable conditions. However speed through water measures
the influence of currents on the vessel, which cannot normally be measured on any other system. It is
therefore important that full calibration is performed at least once for speed through water.
Calibration routine:
As previously explained, there are two factors to be calibrated, heading error and speed. Speed over
ground can be calibrated in two ways. Speed through water can be approximated, but should be
calibrated by sailing on opposite courses to get an accurate value.
All calibration functions are located on the Calibration screen. In order to select this screen, press
“screen select” button in the lower row of the panel buttons and while keeping it pressed, turn encoder
until desired screen appears on the display.
Activation of the hidden menus
To avoid accidental access to the internal settings, all calibration functions are disabled during normal
operation. In order to activate them, do the following:
• Open front door of the cabinet and find a “hidden” key on the component side of the keyboard PCB
(upper/left corner of the PCB).
• Press key mentioned above and keep it pressed for 2-3 seconds, until “Calibration on” message is
observed in the right/upper corner of the screen. The text on the soft keys will change colour from
grey to white, which indicates availability of the corresponding functions.
“Hidden” button
Note: After calibration is finished, disable access to the calibration functions simply by pressing the key
again. Calibration mode is also disabled after a power recycling.

Step 1. Heading error correction:
The vessel sails a steady course in calm waters and the user reads the resultant angle (averaged drift).
This is entered into the system using the Head err button and encoder on menu 3, and adjusted until the
averaged drift angle is zero.
Step 2a. Manual speed calibration/adjustment:
The user enters speed values directly into the calibration table by comparing to other equipment, such
as GPS. This can also be used to adjust values. Menu 2 allows you to enter the values directly. Press and
hold an empty button will take the current values and place them in the table.

adjustment.
Placing values in the BT (Bottom

(Step 2b is recommended).

DL850 270 kHz Operation and Installation
Step 2b. Semi Automatic calibration:
The vessel is made to sail a known distance and course in both directions, this to remove any water current
factors from the speeds.
The 1st leg will show a different speed to the 2nd leg, however the direction changes in the second leg so that
the average is correct.
The speed can be calibrated as follows:
1. Assuming you have performed step 1 “Heading Error”, plot a known distance on the chart. Enter this value
into the
on menu 1.
Figure shows plotting a calibration path on the
chart.
The leg should take at least 5 minutes to sail (distance
can be shorter when sailing slowly). Depth should
be < 50 m to ensure that bottom track also calibrates
correctly.

2. Sail at a straight course in direction A to B and at
a constant speed. When passing to point A, Press
“START leg 1” on menu 1. The button text will
change to stop and a calibrating warning will show
on the screen.
3. The leg 1 measured distance will count up. You
may ignore this. When you reach point B, press
STOP. The system will then calculate the measured
speed (from the measured distance and time)
and the real speed (from the Calibr distance and
time).
4. Turn the vessel and repeat for leg 2 in the opposite
direction at the same speed. The results will show
in the Leg 2 table. The average of the two legs
will show in the final table. This is the correct
calibration.
5. If the calibration looks correct, you may select
which calibration settings table to place it in,
and transfer using the activate calibr ation button
(which will be active if the calibration is within
limits).
6. You have now made a calibration point. We
recommend a point at low speed (1-3 kn) and one at
max speed (20 kn).
7. Once calibrated, check the system at other speeds. If
it is inaccurate, you may add more points (max 5).
NOTE: These values may be overwritten in some software upgrades or if master reset is performed. We
advise recording the values somewhere, just in case. Doppler systems typically have a calibration factor
within 10 % i.e. measured 9 kn, real 10 kn.

Typical Status Screen Contents
The status screen contain information that will facilitate analysis and correction of several problems.
Information from the status and scope screens should be sent by fax/E-mail with any report about functional
disturbances.
If it is at all possible to cycle through the screens and observe this information, several assumptions may be
made regarding operation of the DL850 system. Although some of the subsystems necessary for this basic
system operation may still suffer from minor or intermittent operation disorders, the fact that it is possible to
select and observe this screen, indicate correct operation of the following DL850 subsystems:
1. The CPU board is operating.
2. The keyboard and backlight PCBs are working.
3. The keyboard interface part of the I/O PCB is working.
4. The power supplies on the terminal board are basically working.

The information in the red box on previous page, shows the quality of the signals.
• Link: Shows the internal communication status between display unit and transceiver unit. Errors
in this usually refer to a failure in cabling between the display unit and transceiver unit, but can
also point to a failure inside the transceiver cabinet. (See “Installation problems” in table for more
information).
• Good WT/BT: Shows the quality of the returned Doppler echo. The percentage refers to how many
returns are rejected due to bad acoustic or electrically noisy signals.
• Echo WT/BT: Shows the strength of the returned signals. This will vary depending on the water
quality or bottom range.
• False BT: Indicates how often the system has detected an unreasonably large change in depth. This
can indicate turbulence, objects in the beam, noisy sensors or interference from other systems.
Example: 67/67%. Double parameters show the longitudinal value followed by the transversal.
The other information on the status screen is a collection of information which may be observed and
manipulated with the various screen softkey selections. As a reference, it will often be more convenient
to observe the various settings together on this screen than to cycle from screen to screen to check on the
softkey texts.

Typical Oscilloscope Screen Contents.
1
2

4
This scope screen show oscillograms from the various transducers. The horizontal axis represent time for
the sound to travel down and back from an object or water layer. The vessel is located at the left edge of the
grid, and the right edge represent the range. The vertical axis represent the magnitude of the received echo
signal.
The scope screen allows the user to diagnose many problems within the system. The screen is split in the
following areas.
The red area. The Doppler frequencies and quality parameters:
Each channel has a set of parameters
1. The first line shows the Doppler shift of the water track signal.
2. The second line shows the Doppler shift of the bottom track signal
3. The third line shows the waiting time between ping and sampling for the water track, and is fixed in
time. The figure after the ” / “ shows the length of the return signal before it fades. This gives an idea of
how much signal is reflected from the water particles. If this is very low, the water is very clean or the
transmitted signal is weak.
4. The fourth line is as the third, however for the bottom track. The first number will vary with depth, and
from these numbers you can get an idea of the slope of the bottom. It will also show if the bottom track
Version: 20100129 Sw: 04.02.03
Page 61 of 86
SKIPPER Electronics AS
DL850 270 kHz Operation and Installation
is triggering from something other than the bottom (for example a fresh water layer or fish). After the
“ / “ shows the width of the bottom reflection. This will typically be longer than the transmitted ping and
will get longer on sloping bottoms.
The blue area shows the results of the second stage filters which remove data that varies to far from the
standard deviation. The filter type has a tConst (time constant) which is the number of pings used to approve
a value (a form of rolling time average filter). If data is noisy from ping to ping then some data will be
rejected and the limit is set by the noise peak parameter. The Total WT and Total BT shows how many pings
were used to get the present value XX/YY, where XX is longitudinal value and YY is transversal value.
Example: If the filter (menu 4) is set to medium (40 tConst, 2 kn noise peak) normal operation will give a
total WT of 40-45. A noisy system will give maybe 60-200. The higher the FILTER, the slower the reaction
time of the system. High = Good for stability. Low = Good for dynamic operations. The option run.aver
disables the noise peak filter.
The green highlighted section allows the user to observe the return signals from each channel in either water
or bottom mode. By using the ECHO CHAN button in menu 5, each channel can be selected and detection
points can be observed as well as noise levels. The bottom and water pulses should reach close to the top of
the scope screen, while the noise should be close to the bottom, (first 2 divisions). Higher than this implies
the sensor receiver is malfunctioning or is noisy. The time base (horizontal scale) of this screen can be
changed using the DPT RANGE button on menu 5.
The yellow highlighted section shows the optimised values depending on depth. The set of values for the
present depth are displayed on the screen. These values allow you to compare the transmitted parameters,
with the return signals (in red). These values are set after many hours of testing, and can be individually
viewed on menus 2 and 3. The values can be changed, but this should happen under consultation with
SKIPPER. (More information in appendix 2).
Failures
When a failure occurs with the system, this screen allows the user to perform diagnostics. A failure in the
transceiver or sensor will be observable on this screen. Typically as follows:
1. Single beam failure: A single channel shows eg.”????” (question marks) in all frequency fields for that
beam.
This can be a failure in the sensor head or in an individual channel on the transmitter. Check the scope
(green) on the relevant channel.
Channel 1 = Fwd
Channel 3 = Starboard
Channel 4 = Port?
If one channel is noisy, the sensor element is probably defective. To ensure the failure is the sensor and not
the transceiver, swap the transducer channels inside the transceiver cabinet on receiver connector J502. For
example if the suspected error is on channel 3, swap channel 1 and 3. Repeat this procedure on transmitter
connector J503. (See diagram of wiring in appendix 1, sensor cable connection )
Remember to turn off power at mains before attempting this!
Version: 20100129 Sw: 04.02.03
Page 62 of 86
SKIPPER Electronics AS
DL850 270 kHz Operation and Installation
The result of this will probably be that the “?????” (question marks) will move to the new channel. This
confirms that the fault is in the sensor or cable. It it does not move, the fault is within the transceiver cabinet
(either transmitter or power card).
Take 3-4 pictures of the screen with a few seconds interval and send by E-mail to manufacturer.
2. All channels “????” and below (question marks) in red area.
If all channels are ????, the fault is most likely the power supply to the sensor. Check all terminals on J502
and J503 are fastened securely and correctly (See diagram of wiring in appendix 1, sensor cable connection).
If the temperature is also wrong (e.g. -4) the problem is most likely the sensor power supply. Measure the +
- 9V power supply to the sensor (pins J502 p20-21 and 23-21) with and without the sensor wires attached. If
the voltage drops considerably with the sensor power attached, the sensor is most likely faulty, although the
power card is also suspected. If the problem is not identified here, refer to further instructions available as a
data bulletin on the SKIPPER web site.
MASTER RESET PROCEDURE.
In some cases the display cabinet may get “confused”, or the user has “adjusted” too much. Performing a
master reset procedure will return all values to factory default settings
Before performing this, note your calibration settings, and setup for inputs and outputs as these will be lost
during this procedure.
• Switch off the display unit using the internal toggle switch(es) and wait a few seconds.
• Then press down and keep pressed the softkey to the far right and far left (no. 1 and 6) in the upper row
on the keyboard (softkeys).
• Turn “on” the display unit, and keep the two softkeys pressed down until the screen shows the normal
picture. This may take as long as app. 30 seconds.
• You should now normally hear 4 ‘’beeps’’.
Note: You will now have to re-apply your settings for calibration, input/output and screen settings

Note: The performance widely depends on the hydro acoustic properties of the water column (aeration

rolling and pitching. These effects can lead to occasional failure of the system or to incorrect indication
of speed and distance (unstable or too low values).
Note: The stated data for depth ranges and accuracy are not valid for unfavourable conditions. Since the
speed accuracy depends on the sound speed (affected by salinity and water temperature), it is important
to adjust (manually) this parameter for particular operation area, (screen calibration, menu 3).

This function allows to display oscillogram in
the graphical window from any channel in both
water track and bottom track modes. It will allow
examining shape and amplitude of the returned
signal in each individual channel. Note: This
function delays signal processing and must be set to
“Disabled” during normal operation to reduce latency
of the system.

The echo sounder function
The echo sounder (ES) function is disabled by default, and the control softkey is not available. To enable the
softkey (screen pilot, menu 2), it necessary to press the hidden button (inside the cabinet) and keep it pressed
for about 12 seconds (third beep must be heard while pressed). If the same procedure is repeated once more,
the ES softkey will not be visible again. In this case the echo sounder presentation will also be removed
from the screen.
The various softkey menus are selected by pressing repeatedly the MENU button on the left side of the
softkey menu. The number on the button (1 – 6) indicates present active menu.

13. Appendix 4
Upgrading Software
New software versions are released from time to time. The DL850 with Compact Flash (CF) can be updated
by performing the following software upgrade procedure.
1. If you have received a programmed compact flash, skip stage 2.
2. Copy the received/downloaded software file into the root folder of Compact Flash card. The name of the
file is not relevant. Also copy the latest version of setup.exe into the root folder.
Note: Standard Compact Flash reader is needed to be attached to the PC.
Note: It is possible to use the Compact Flash card, which is already installed in the display unit.
3. Switch OFF the mains of the display unit and insert Compact Flash card with the new software on it.
4. Press the “hidden” button inside the cabinet (mounted on the solder side of the keyboard). Keeping the
hidden button pressed, switch ON the mains in the display unit and keep the button pressed while the
message “You may release the hidden button” appears in the lower part of the screen. If a new setup.exe
is to be loaded, follow the on screen instructions.
5. Release the hidden button. After few diagnostic text messages, the list of available software versions will
appear in the lower part of the screen as in example below.
6. Note: If the bootloader does not find any file with the software on the Compact Flash, the presently
installed version will start automatically. In this case, make sure, that the upgrade and setup file has been
copied correctly on the Compact Flash and repeat procedure.
4.01.18
Active
4.02.03
External
7. Select a software version, which you would like to install. Normally, it is possible to chose one out
of two: the version, which is currently installed in the internal memory (indicated as Active) and the
upgrade version (indicated as External). The version name is displayed in the upper line of the text lines,
located just above the corresponding softkey. In the example above, soft key #2 should be pressed to
select the latest software version.
8. Confirm selection by pressing YES button (or go back to selection, pressing NO).
9. Press any button to start the upgraded software (or it will start automatically in 5 seconds).
10.Note: The file with a previous software version will be copied back to the Compact Flash card, so it
would be possible to re-install it in the similar manner, if desired.
