This Manual is for the DL2 part of the DL21 system, due to changes in the regultations for
Wheelmark (MEDB) The optional Alerts previously in the system have been removed. This is due
to introduction of the IEC62923-2018 BAM standard.
Alerts are not Mandatory in speed logs (SDME). Relay outputs for power failure are still available.
Contact SKIPPER support for more details.
The DL2 system is no eected

In addition, the following symbols are used
Indicating that the information presented is partly from the GPS input, and therefore not
from this sensor. (outputs may show invalid data in this mode)
Symbolising that the data presented is longitudinal (forward or backwards for aft)
Symbolising the data is transversal (port or starboard)
Symbolising the resultant speed direction
Simulator Mode - The system is using a simulator to generate the speed and depth

The Dual and single axis Doppler speed log system (DL21) works by the Doppler principle. This
principle is that a sound bouncing o a moving object will change in frequency. This principle can
be utilized by making a narrow beam of sound and analyzing the frequency of the returning sound.
This frequency change is proportional to the relative speed of the reecting object.
On a vessel, a transducer is positioned pointing slightly in one direction and the reected sound
comes from particles in the water (STW) and the bottom (SOG). The frequency of these echoes
is translated to speed. By having 2 transducers pointing in 90 deg directions, the speed can be
measured in two axis.
The DL21 sensor sends from both beams and both sensors at the same time. The transducers are
moulded into the same sensor head together with the ampliers and detection circuitry (transceiver).
In addition, the sensor sends at two frequencies giving accurate values. The DL1 part of the system
is independant and isolated. It also uses 2 beams at a higher frequency, pointed ahead and AFT.
The system is default congured to show STW from the DL1 part of the system, and SOG (2 axis)
from the DL2 part of the system. The DL2 part can be recongured to also show the STW (2 Axis)
from the DL2 part, but this may cause a little confusion if the ahead speeds are slightly dierent due
to the DL1 measuring slightly closer to the Hull
The sensor also contains temperature sensors and tilt sensors to allow compensation of the data.
The transceiver contains a small computer which processes the data and signals and converts them
to speeds. This data is sent to the electronic unit (JB70D21-XX) where it is formatted transferred
to the display and presented on screen , and as data in formats to be integrated into the vessels
navigation and presentation systems such as repeaters and conning. this manual is for the DL2
graphic display part of the system, the DL1 part is covered in a dierent manual

The screen presents speed through water (STW) used for the autopilot, radar and logged on the
voyage data recorder (VDR). The speed data can also be used for setting limits on the rudder and
stabilizer wings. It also shows speed over ground (SOG) used as a primary system for speed. Some
of this information is also available from the GPS systems. By adding an approved gyro heading
input into the system, together with parameters of the vessel, it is possible for the system to calculate
the transversal speed at any point of the vessel. This feature known as docking, allows the pilot to
be sure that both the fore and aft of the vessel are under tight control.
This system does not contain any alerts, however a power failure relay is available
In addition the system shows distance travelled through water, and distance over ground and has
a resettable daily trip counter. This information is used for service intervals and navigation. Extra
information is available regarding the sea temperature and tilt of the vessel. Note. The Distance over
ground measures only when the bottom is within range.
The user can operate the system via a touch screen or using an application on the conning unit.
The displays are intuitive and have a menu system, but also allows the user to click on the screen
to adjust the relevant parameters. Full setup, calibration and diagnostics are available from the
screens. Calibration is performed by a two leg sailing procedure, and once set, should not need
repeating unless the sensor is moved.
The system is low maintenance. After initial setup and calibration, the system requires no attention
except to change alert parameters if required. The sensor is exposed to the water and over time
some growth may appear. This can be carefully removed when possible, and is normally not a
problem except if the vessel is still for longer periods of time (weeks) in warm waters. The eect of
this growth is usually seen as the range of the bottom track being reduced.
The system has comprehensive built in test (BIT) that can be used to analyse the performance of the
equipment and give a warning if the data is not within specication. It also has inbuilt redundancy in
some areas, such that even if a failure occurs, it can still give some data. Due to the systems LAN
network point, it is possible to set up the system for remote diagnostics and upgrade using network.
In time this will help reduce service visits and increase the probability of rst time x. Inserting a USB
stick into the electronic unit causes the system to log all the available parameters, and these les
can be sent to skipper or your service provider to diagnose errors in the system

Pages can be changed by using the “Navigate” arrows on the lower right side of the screen.
In each of the pages A-E the main area is programmable to enable/disable required information.
Page A is not possible to disable. SOG is always on in page A.
Conguration and enabling of pages is performed in “cong” See “Runtime Screen setup”
The brightness can be set from 1 to 100%.
If an unacknowledged alert is present, the screen cannot be dimmed to the lowest settings.
If the screen is dimmed too low to see. press and hold on the left of the screen, the dimming will
raise itself to default (50%)
