INTRODUCTION
The DL1-MuLTi DoppLer speeD Log sysTeM
The DL1-Multi single axis Doppler speed log system is a vessel mounted system
that measures speed in one axis (longitudinal) through the water. The system
fulls all class and type regulations based on MED B (wheelmark).
The system requires no external inputs, however adding inputs from other
navigational systems enhances the functionality and allows comprehensive
quality control of the data.
The system comprises of 3 units;
1. The control unit – The system requires a small control unit (CD402CU-XX)
to display and set up the required parameters. All setup parameters are also
available by connecting to the electronic units web page via a LAN cable.
2. The electronic unit – This unit (JB70D1-XX) comprises of a processor/IO
board and a power supply. It is packaged in a compact single euro cabinet.
This units electronics enable the user to interface to both modern and older
navigation systems with all the expected connectivity. The unit has a built-in
web server, allowing the system to be fully integrated into existing navigation
systems (extra approvals may apply).
3. The sensor – The sensor (DL1SXX-XX) contains 2 acoustic elements and a
fully programmable transceiver unit, allowing the system to adapt itself to the
conditions and requirements. In addition, the sensor contains a temperature
sensor for internal compensation and quality control.
4. The sensor is installed into a sea valve or tank welded into the hull.

CHAPTER 1: HARDWARE MOUNTING
pLaceMenT of The speeD Log sensor anD BoTToM insTaLLaTion
When placing the speed log sensor, consider the following moments:
• The DL1 doppler sensor measure speed of water in a distance 0,5-3m away from sensor.
2 acoustic signals, one pointing 30deg forward and the other pointing 30 deg aft.
• The sensor is installed into a sea valve or tank welded into the hull.
• It is necessary to select a part of the hull that is submerged and free from turbulence and
aeration under all load and speed conditions, and to avoid positions where air is trapped in
heavy weather.
The generally best placement on larger vessels is in the front region of the vessel just behind the
bulbous bow (see area A on g ). This area is generally designed such that the bubbles are pushed
to either side of the bulb, leaving a clear area under the bulb and just behind.
• Do not mount transducers aft of bow thruster outlets, or aft of other hull installations (such
as outlets, vents or other protruding details) that may create aeration or turbulence.
• Welding seams in this area should be smoothed and rounded off in order not to create tur-
bulence or aeration and maintain a laminar waterow at all speed ranges of the vessel.
• Select an area that is acoustically quiet. The system operates at frequencies between 700
kHz and 740 kHz.
• If the bottom is sloped a housing (blister) should be constructed. It is recomended to allow a
at area of at least 30 cm in front and behind of the sensor and form the bed as a tear drop.

best sensor placement in the
front region.
Recommended mounting area
A sea valve is highly recommended over a tank installation, as it is possible to service the sensor
(clean or replace) without docking the vessel.
The best place for sensor installation is in a dry and accessible area like bow thruster room, just in
front of the fore bow thruster, as deep as possible on the hull.
Even though sensor is approved to be installed in wet areas like ballast tank it is not recommended
If installed in a wet area special care to maintenance and maintenance access should be taken. A
dry void space is recommended. A junction box for sensor cable should be mounted close to sensor
allowing sensor change.
The sensor cable (green) is waterproof and carries digital signals to and from the sensor and power
to the sensor. It must pass through the outer hull using a double water seal. This is included in the
bronze tube in sea valves, or in the tank and stufng tube. The cable is 11 mm in outer diameter with
a bending radius of 25 mm. The cable can be cut if required.
Please refer to separate manuals for bottom parts.

sensor orienTaTion
Tank mountings have an orientation (an arrow that must point forward) see next page. Single
axis speed logs do not have the possibility to correct heading error electronically and must
therefore be mounted in line with the hull (within 2 degrees).
Orientation in Sea Valve
The sensor is typically mounted after the vessel is in water. Care must be taken that the ahead mark
on the bottom installation is correct (seen from the inside by the at edge being on port side).

DocuMenTaTion of insTaLLaTion.
Before vessel is launched from dry-dock it is important to make documentation of hull installation.
By providing the pictures in below registration card it may help us understand how the bottom
equipment is installed. It is very expensive and time consuming to provide these pictures after
vessel is launched.

pLaceMenT of The conTroL uniT (cD402cu-XX)
If required, the control unit is placed on the bridge. Some standards require
some operations of the unit to be available from ‘standing position’, and in
this case the unit must be near the steering position. However, it is also
possible to control some of these settings from multi-repeaters with 2-way
communication (ex: CD401MR-SB) In which case, the Control unit can be
placed on, for example, the navigation table.
pLaceMenT of repeaTers cD401Mr-XX
Repeaters are typically installed on the overhead console and/or the bridge wings. These can be
routed using NMEA signals These require a local +24 V DC supply.

CHAPTER 2: WIRING
eLecTronic uniT
All parts of the system are connected to the electronic unit. The electronic unit has pluggable spring
loaded connectors, as well as an RJ45 LAN interface.NMEA (4 output, 1 input ports), pulse, AUX
(control signals) and optional analogue output signals can be connected.
The electronic unit requires either 24 V DC or 115 - 230 V AC (50 - 60 Hz), max 60 W.
Both can be connected simultaneously. If required, a separate AUX 24 V supply can also be
connected.
The supplies are not internally isolated and ground will be connected to chassis at a single point
(The screw between the DC connectors),
Cables to and from the cabinet should be grounded to the grounding points on the chasis using a
faston spade (type AMP - 140814-1 - TAB, FASTON, Example mating part 5-160447-5 - CRIMP
RECEPTACLE)
The JB70D1-XX does not contain a physical ON/OFF switch (only software in sleep mode) and
should be connected to a fused circuit breaker.
connecTing sensor To eLecTronic uniT
The sensor is provided with a 40 m cable. This can be cut, or extended (see wiring diagram for cable
spec). The individual internal wires can be spliced or connected using a JB12 junction box.
sensor caBLe pLug
Cables should be connected as shown, leaving approximately 3 cm of tail. They should be stripped
with 6-7 mm of metal showing and these should be connected as in the diagram above. A small
screwdriver with blade size approx 3.5 mm, can be used, although WAGO part no 210-719 is ideal
for this use.
in a ground stud on the edge of the cabinet. The outer insulation should be cable tied to the plastic
handle of the connector, and securely anchored nearby. The plugs, when retted, must be installed
such that their clips are fully in the up position.
If yard cables are too thick or heavy to clamp, anchor the outer insulation nearby, and feed the inner
cables to the connector.
If the connector is missing, lost or broken, replacements are available from Skipper (PN ZZN-01121)
or Wago (part no. 713-1112/037-000)
grounDing
A general rule is that cable shields should be
grounded in one end of the cable only. The DL1
sensor contains a grounding point internally and
this is connected to the outer shield of the cable.
This cable does not need to be grounded at the
dry end.

The JB70D1-XX system has 1 NMEA isolated input and 4 output ports driven separately from a single
com port, each capable of delivering 20mA. These are marked in blue and can be programmed to
give out a number of messages. In addition, the LAN port can be used to provide the same formats
using the IEC61162-450 standard. However, it should be noted that this port will normally also send
out proprietry messages with information to the CD401CU-XX control unit. Approved messages are
sent at a 1 second interval, and are marked with the ‘VD’ identier. Data is sent at 4800 baud, 8
data bits, 1 stop bit. The inputs require 2ma when the voltage is limited to 2V. Generally the inputs
use 2.5 mA if available.

Auxiliary input and outputs are electrically isolated and require a small voltage on the input to work.
The labelling of the system is set up for the most common wiring conguration. All the pulse inputs
and outputs are programmable and can be congured in the web menus to perform a number of
tasks as shown below.
Aux in (marked ALRM RST IN on CN1 pin 16 and 18) can be switched to the following options:
- Dimming Up
- Dimming Down
- Forward reverse (for 2 directional systems) To activate this go to the DL1 web page.
There are 3 Aux Outputs:
- Pulse out (default Aux Out1)
- Power failure alarm (default Aux Out2)
- Speed warning, min/max range set by the user (default Aux Out3)

Connect the units together and use SKIPPER
service software to nd the relevant settings,
alternatively address indivdual units using
their IP addresses from a web browser
If no switch is available, connect directly to each
unit and use its web page to setup. Multirepeaters
can be set up directly from the screen.
CHAPTER 3: SETUP LAN COMMUNICATION
Both the Control unit and the Electronic unit have unique IP addresses, and system identication
numbers. These are adjustable via the web page, but the default values are shown on the serail
number labels. If changed it is recomended to make a label with the new address.
Startup requires the following steps:
seTup using skipper service sw
For setup of IP adresses, Id and port please use
SKIPPER service software.
Available as download from:
http://www.skipper-service.no/skipdoc/data////Software//
SkipperServiceSoftware/SetupProjectServiceSoftware.msi
Start “Com Setup”
Note! If no DHCP server on network then change
your PC TCP IP settings to “xed IP”.
Press “Find multi systems”
The software will search for SKIPPER products and present a list with settings. A table wth all the detected
system will be generated. and from this table it is possible to congure the units. Each Electronic unit
JB70D1-SA must be paired with a control unit (CD402CU-SC) This is done by adding the identication of
the JB70D1 unit to the Control units pair eld.
If more than one control unit is to be used on a single Electronic unit then the eld Pair eld on the
electronic unit (JB70D1) can be left blank. Otherwise enter the ID for the paired control unit.
Note. All units that are to detect eachother must be in the same Group. this is by default NAVD.
System ID: The unique (SFI) ID of this unit

Turn on the electronic unit and contol unit (if attached). The electronic unit will attempt to self-
connect, and go to the system setup screen. If the control unit is not available or does not work,
(possibly IP clash) it will show a single ‘ERROR’ on screen, in this case connect a LAN cable to a
RJ45 connector.
Go to web page (default IP address 172.16.1.104 for JB70D1 or 172.16.1.103 for CD402CU,or to
the labelled IP address. From here you have access to the system setup page. If you can not make
contact by the above methods, use the SKIPPER service application (available from the web site,
select the correct interface unit, and follow the instructions.
In accordance with the IEC61162-450 LAN interface standard, the System Unique identier (default
VD01XX where XX is the serial number) and Group (default NAVD) can be adjusted. The LAN
works at 100BaseT speeds. A typical payload will be 2-7 kB/s

cD402 conTroL uniT seLf TesT
The user can run an internal system test, run individual hardware tests and report as pass or fail.
The tests are designed to check the functionality of the input and output. Some require a loop from
an input to an output.
Test 0: Check LEDs on CD401CU-XX control unit.
Test 1: Check internal memory.
Test 2: Check two way communication to the sensor.
Test 3: Send out a full length NMEA message on NMEA outputs.
Test 4 Send out a full length NMEA message on sensor outputs.
Test 5: Used only for manufacture test
Test 6: Used only for manufacture test
Test 7: Used only for manufacture test
Test 8: Used only for manufacture test
Test 9: Used only for manufacture test.
Test 10: Show Raw data from the sensor, and Quality factor
Quality factor is a value from 0 to 8 showing how strong the signal is relative to the noise. If the
installation is poor, the noise may rise reducing this number, also if the return signal is weak, this value
will also be low. Each unit is 3dB signal to noise ratio. The system is suspect with values below 3. .
running in DeMo MoDe
Once all parts are installed, the system can be made to run simulations of real situations. These are
found in the demo setup.
The system has 4 demos:
Demo 1: Slowly ramps a speed up and down. This allows the user to monitor
speed outputs, to set and trigger alarm (which can then be reset).
Demo 2: Fixes a speed on screen. This can be preset in the web page.
Demo 3: Transmits a xed speed of longitudinal 5 kn and transversal 1 kn.
Demo 4: Simulates a speed on the sensor by pinging at the equivalent Doppler
frequency - select the desired speed and press “SET”.
All these demo/simulations will cause an ‘S’ to ash in the corner of the
CD401CU-XX control unit.

CHAPTER 5: SEA TEST AND CALIBRATION
A speed log will require calibration of speed after installation.
There are 2 types of calibration procedure
1. Auto Calibration
2. Manual Calibration.
Auto Calibration is designed to ignore water current effects.
The procedure requires the vessel to sail a xed length track at a constant speed. To remove the
current and wind effects, the same track should then be sailed in the opposite direction at the same
speed.
The average of these tracks will be used to calculate the speed difference between the real speed
(measured using the actual distance and the time it took), and the measured speed (using distance
from the sensor and the time it took).
This procedure must be performed at least once and then other speeds checked with the GPS or
manual calibration.
A calibration procedure may be performed from control unit or web browser.
For Control unit procedure please see operation manual.
For Calibration on web page
Open web browser with I.P. adress to JB70D1 Electronic unit.
Goto Calibration and start “Auto Calibration”
Set distance of rst leg. The leg should take at least 5 minutes to sail (distance can be shorter when sailin-
slowly). Example: A calibration point at 5 knots the distance should be 1nauutical mile.
If necessary, the procedure should be repeated at different speeds. SKIPPER recommend that
calibration is performed at a low speed and a high speed.
Draw a line on the chart with the required distance. Point A in start and Point B in end.
Start rst leg. (The vessel crosses point A at the
calibration speed, towards point B).
• Stop rst leg. (The vessel reaches point B on the chart
and turns to sail the line in the other direction).
• Save rst leg.(If the presented speeds look correct, save
the leg and continue).
• Second leg, option. (If you do not have the possibility
to turn the vessel, you can use the rst leg data directly.
If the rst leg data is of poor quality, you may not be
given the option to continue).
• Start second leg. (The vessel crosses point B sailing
towards point A, sailing at the same speed as leg 1).
• Stop second leg. (Press as the vessel passes point B)
• Calibration result and save option. (The user can
decide to accept or reject this calibration, and in which
memory position to save it)

4: Start RAW data modus
During RAW data measures data baud
rate will change from 4800 to 115200.
The baud rate will automatically switch
back to 4800 when stopping the RAW
data or by power off/on the unit.
(Outputs of the system will stop while
RAW data is active. Display will show
“ERROR”)
5:The RAW data will be shown as two graphs
At 0 knots speed the highest point of graphs will be at at the
same point. (Frequency)
In speed the the tops will move from each other. This is
caused by the doppler shift in frequency being positive for
forward channel and negative for aft looking channel.
Signal strength
A noise top will interfere on
the speed measure if larger
than the speed top.

CHAPTER 8: SPECIFICATIONS iec61162-2 high speeD nMea coMMunicaTion
This standard requires a common signal ground between system requiring extra circuitry for isolation
on the receiver side. This unit does not have this circuitry, and cannot fullll the receiver part of
the standard, however by connecting the common signal ground to pin 10 marked Common, the
transmitting part of the standard is fulllled.
iec61162-450 eTherneT coMMunicaTion
The system is dened as ONF2 and SF,NF as per the standard (§4.1). This means it will send and
receive encapsulated messages as dened in these standards, but has in addition web pages with
a seperate IP address. The -450 standard requires the UdP multicast messages to have a unique
identier, and transmission group. See “” on page 39
The system can be connected to a standard network using CAT 5 or better cables, the system will
load the network with a maximum datarate of 20Kb/s (typical 3Kb/s). and will operate a network loads
of up to 20 Mb/s or 10000 datagrams per second. The maximum number of datagrams directed to
the unit must not exceed 2500/second (normal usage is 3-5).
Error codes are logged if the formats are not accoring to specication. These messages can be
retrieved and viewed using the “Upgrading and external diagnostics of the system” on page 35.
The CD401CU must be paired to the JB70D1 unit, this to make sure the CD401CU talks only to one
electronic unit on the network. To do this the user must enter the SFI ID of the JB70 unit into the
web page of the CD401CU. For example VD0133, if the unit is only to have 1 control unit, then the
control unit SFI ID can be entered into the JB70 unit. if no SFI is entered into the JB70D1, then any
CD401CU with the correct destination SFI will work, allowing multiple control units.
