1.
Purpose of this Manual
This operator manual describes how to operate the WASSP System Multibeam Sonar
System program through its graphical user interface. There may be variations due to on-going
developments and enhancements.
2.
Introducing the WASSP System Multibeam Sonar System
The WASSP is a multibeam Sonar system that uses a wide-angle sonar transducer to profile the
water column and seafloor to a high resolution. It is this unique combination of multibeam sonar
and computer processing power which provides you with unparalleled information about the
underwater environment. It gives you a wide 120° port-starboard swath of the water column and
seafloor, allowing you to find and position reefs, wrecks, and objects in the water column or on
the seafloor. From the 120° swath, the system processes 224 dynamic beams, with each beam
containing detections from the water column and seafloor.
The information is presented in a user-friendly, mouse controlled, Windows-based operating
system. The system can output data to plotting software packages. For optimal performance,
roll, heave, pitch, heading and position inputs are all required.
Mapping an area of the seafloor requires motion compensation to compensate for the motion of
the vessel. The efficiency of motion compensation strongly depends on the quality of the motion
data. Accurate ship measurements must be taken and the dockside and sea trial commissioning
procedures carried out thoroughly during installation. Even with good sensors, mapping
performance in rough seas will be less accurate than in calm water.
The WASSP System can be applied to a variety of survey methods, as well as search and
rescue, customs, and police applications.
2.1
Main Features
The WASSP System has the following main features:
►►
►►
►►
►►
►►
►►
Simple to use
Improved performance
The use of separate transmit and receive arrays has enabled WASSP Ltd. to optimise both
transmit performance and receive sensitivity, giving improved performance over traditional
sonar and sounders.
High detail picture of the marine environment
The transmit beam spreads over a 120° port-starboard swath and covers 4° fore-aft while
the receive beam covers 10° fore-aft, displaying a highly detailed picture of the marine
environment.
Beam stabilisation
Beam stabilisation compensates for the movement of the vessel, providing accurate seafloor
profiles.
Variable beam width
Unique to the WASSP, the single beam view can not only be stabilised, but the beam width
can be varied from 5° to 40°.
Bottom lock
Bottom lock provides a traditional bottom lock mode where the changes in bottom depth are
ignored and the bottom is drawn flat. Echoes are shown relative to the flat bottom image,
enabling better discrimination on the seafloor.

Computer based profile storage
A computer-based system means the WASSP can generate and store very detailed seafloor
profiles.
160 kHz operating frequency
Operating at a frequency of 160 kHz provides high seafloor definition with a large range.
Depth and seafloor coverage
Seafloor coverage is determined by the beam width in use: For a 90º beam width, the
seafloor coverage will be approximately twice the water depth. For example, 100m depth
gives 200m seafloor coverage. For a 120º beam width, the seafloor coverage is 3.4 x depth.
For example, 200m depth gives over 600m seafloor coverage.
Unique power management system (14 power levels)
14 power levels provide optimal performance over a wide range of seafloor types and water
depths.
Efficient seafloor mapping
Profiles 90 times faster than conventional single beam echo sounders, leading to reduced
costs and improved accuracy.
Future proof technology
The computer based operating system and BTxR firmware are both upgradeable as new
features and methods in software are developed.
Third party integration
Through interfacing, real time to third party software applications and outputting to standard
formats, bathymetric and water column data can be collected and processed using specialist
tools.

4.8.2 NMEA
For the WASSP system to perform effectively, motion, position, heading and heave sensors are
required. The overall performance will be directly affected by the quality of the sensors chosen.
The sensors will have been set up during Commissioning. See the Installation Manual section
“8. Sensors” on page 26 for full details.

4.8.4 Sound Speed Tab
Sound speed varies with temperature and salinity, so this changes throughout the year. Use a
temperature sensor to set the sound speed if possible. Otherwise, the operator should become
familiar with this process themselves and adjust on a regular basis (at least monthly) as
necessary.
The Sound Speed tab allows you to set surface speed correction settings for fresh and sea
water. Valid values for both sea and fresh water range between 1000 and 2000 m/s.
Knowing the temperature gives a close approximation for the sound speed. In Manual mode the
Surface Sound Speed can be modified directly or computed from the temperature and salinity
values.
Refer to the section “10.2.4 Sea Trial - Commissioning Step 11 : Sound Speed” on page 51 of

4.8.5 Sensor Values Tab
The Sensor Values tab provides a selection of motion compensation options and corrections
for sensor misalignment. These settings should not be changed by the operator outside of the
commissioning process.
Figure 19. Ship Setup Options – Sensor Values Tab
The values under Current Values are the selected live motion readings from the NMEA sensors
that the WASSP system is connected to and reading from (with offsets applied).
If roll correction is enabled and configured correctly and the vessel is rolling less than 15°, the
sonar picture should remain on almost the same angle from ping to ping on flatish ground.
If the sonar picture rocks as the vessel rolls then the roll compensation setting is likely to be
wrong or the motion sensor is not being read by the WASSP system. Refer to Installation
Manual “10.2.8 Sea Trial - Commissioning Step 15 : Pitch and Heading (Optional)” on page

4.8.6 Power Tab
The Power tab reveals three Power Options:
4.8.6.1Manual Power
This setting allows the user to choose any system power level using the Power Level on the
Menu Task Bar (See “4.5 Power Level” on page 15).
4.8.6.2Auto Power by Depth
Auto Power by Depth displays 14 power levels, seven in the low range and seven in the high
range, that can have each level individually set from fourteen drop down boxes. A Defaults
button sets all fourteen power levels to a default setting. When setting power level depth
settings individually, click the green Tick button when you have completed the settings.
Note: Automatic Power will
only work when the Power
Indicator is Green or Blue!
Absorption Loss
Note: There are TWO
different Automatic Power
modes. Automatic Power
by Signal and Automatic
Power by Depth. Automatic
Power by Signal is better for
seafloor mapping out on the
sides near the seafloor.
Figure 20. Ship Setup Options – Power Tab
If a power level is set out of sequence, for example level 5 is set to 14 m, level 6 is 50 m and
level 7 is 40 m, then a WASSP information box appears and informs you that a specific power
level is invalid (level 6 in our example). Level 6 can then be set individually to a level below that
of level 7 and above level 5.
Click the tick and reset Power Level 6 to a level between Power
Levels 5 and 7.
If no other power levels have been changed, clicking “Defaults” will
reset the power level.
4.8.6.3Auto Power by Signal
sets the power based on the maximum acoustic echo received (normally the seafloor). The
received level is set to prevent saturation of the receiver. This should provide the best overall
system performance.
4.8.6.4Absorption Loss
As sound travels through water, some of the energy contained is absorbed by the water,
resulting in attenuation of the signal. The chosen value of absorption loss is used when
calculating backscatter. For a 160kHz WASSP system, a default value of 40dB/km is used. This
is set at time of installation and should not be changed without a clear understanding of the
absorption properties of the water in the area you are working in.

4.8.7 Processing Tab
The Processing tab contatins the options for 3rd party output and sonar processing.
4.8.7.1Third Party Output Options
The output format to third party software can be selected here.
►►
►►
If you are outputting to the HYSWEEP® module of HYPACK®, select the HYSWEEP® output.
See “9. Hydrographic Software Integration” on page 31 of the Installation Manual for more
information.
If you are outputting to QINSy, select the QINSy output.
If you are having trouble receiving NMEA sentences from the installed sensor, or if your sensor
is not supported by QINSy or HYPACK® but is supported by WASSP, enabling the output of HDT
and TSS may fix this.
4.8.7.2Beam Distribution
►►
Equal Distant
This distribution sets the sonar beams at a fixed separation across the swath, resulting in
a seafloor line with evenly separated detection points. This will give a more even sounding
density:
►►
Equal Angular
This distribution sets the sonar beams at equal angles from port to starboard, meaning that,
on a flat seafloor, the detection points are more numerous near the middle of the swath, and
less numerous at the sides, putting more soundings where the soundings are likely to be more
accurate:
►►
Ignore Degrees to:
Adjust the swath width if you find that
detections at the swath edges are
causing issues with seafloor mapping.
e.g. With 10º ignored on each side, the
middle 100º of the swath will be used to
map the seafloor.
In rough/noisy conditions, this could
save time on post-processing.

4.9.3 Tides Window
The Tides window allows you to change the way WASSP System uses
tide information. Assuming the Disable Tides check box is cleared, the
WASSP System uses the GPS positioning information coming through
the computer communications port to automatically select the closest
tide station. The WASSP System then calculates a tide offset value and
adjusts the seafloor profile data using the tide offset value.
Selecting the Disable Tides check box can cause the seafloor depth to vary as the tide waxes
and wanes, resulting in inconsistencies in seafloor mapping. Disable Tides when operating on a
lake. With the Disable Tides box cleared (default), the tide settings are constantly updated. The
Tides button displays tide information for the operator.
The Local Time Difference box shows the difference in hours between coordinated universal
time (UTC) and the local time. For example, if you are in New Zealand waters outside the period
that includes daylight saving, the Local Time Difference setting should be set to 12, the number
of hours New Zealand is ahead of UTC with daylight saving. So if UTC is 10.00 am and local
time is indicated as 12 hours, then the local time would actually be 10.00 pm.
The Database tab allows selection of either the default tide data file or the European tide
database. Vessels operating in Northern Hemisphere waters may get better performance from
the tide information by selecting the European tide data.

Sonar View
The sonar view shows the water column and seafloor profile below the transducer. This
represents a sonar view of the water column and seafloor as seen from behind the vessel. See
“Figure 29. The Sonar View showing the seafloor line”.
If there is a secondary sonar
or sounder operating on the
vessel, you may see pulses of
interference from this device on
the Sonar, Single/Triple Beam
and Sidescan displays.It is
highly recommended that any
secondary sounders are turned
off in order to receive the best
signal.
A 120º wide by 4º long swath or footprint is covered. The
system generates 224 beams over the 120º footprint to provide
a very high-resolution sonar view. The centre 90º of the swath
or footprint is used to develop seafloor profiles and gives a
seafloor coverage of twice the depth (e.g. 100 m depth gives
200 m seafloor coverage).

Sidescan View
The Sidescan view is a Sidescan picture generated from the sonar data received by the system.
The display is drawn on the screen as a waterfall – the newest information appears at the top of
the screen, while the oldest falls off the bottom of the screen. This is similar to the way sounder
displays operate, except that in their case the new data appears on the right and the old data
disappears off the left of the screen.
The left side of the Sidescan view shows the signals received from the port side while the right
shows signals received from the starboard side. By default, the Sidescan view starts at the
centre of the vessel and works its way out to port and starboard.
As the Sidescan image moves further out along the seafloor, the picture shows features on the
seafloor. Objects, such as rocks, appear as bright white marks followed by a shadow. Harder
ground gives strong returns (lighter on the grey scale), while a patch of mud or kelp causes a
dark patch/shadow to appear. See “Figure 34. Sidescan View”
The primary advantage of the Sidescan view over the other views is in locating and identifying
objects on the seafloor off to each side of the vessel. Some structures such as a shipwreck may
appear like a large fish school on the other views.
In “Figure 34. Sidescan View”, the Sidescan view allows you to interpret the sonar information
from a different view point, showing a wreck just above the seafloor as a clearly shaped
structure.
Due to the nature of the origin of the data, any signals of significant strength register as a faint
mirror on the opposite side of the display. Standard Sidescan systems generally rely on a towed
transducer that is held deeper in the water, having the advantage of a lower aspect ratio.

Waterfall View
The Waterfall View displays a “3-Dimensional” view of the seafloor made up of discrete points
representing every seafloor detection point generated for each ping. The data shown on this
display constitutes the raw points sent to third party software such as WASSP Navigator,
HYSWEEP® and QINSy and that saved to GSF.
This display allows easier detection of small objects on the seafloor as well as a clear display
of the state of seafloor detection, allowing features or noise/interference/error sources to be
identified early in the processing pipeline.
The data is displayed in a successive fashion, with an option to separate each ping with a
defined spacing useful for compression or expansion (Fixed), or to set the spacing relative to
the vessel’s speed (Actual).
The following methods are used to control the Waterfall View:

Troubleshooting
If the WASSP System program provides no data when you transmit, check the following:
►►
►►
►►
Ensure that all cables and connections have been installed correctly. For example, Ethernet,
cables, GPS, NMEA sensor, and so on. Refer to Installation Manual for details.
Software installation and settings. See “Checking Software Installation” procedures below.
NMEA data sentences. See Step 5 of the “Checking Software Installation” procedures below.
6.1
Checking Software Installation
To check the software installation, proceed as follows:
1
Confirm the WASSP Processing Module (
Task (
) and the Transfer
) symbols are present in the Windows Task Bar.
If either are not in the Task Bar, run from Start > All Programs >
WASSP
2
Right-click the WASSP Processing Module symbol.
Click Show.
The WASSP Processing box appears.
3
Make sure that BTxR, Transfer Task and WASSP GUI are shown
as connected.
If not connected, check that power to the BTxR is ON and the
ethernet cable is connected between the BTxR and the computer,
and plugged into the correct ethernet port.

7.1
The System is transmitting too slowly, how can I speed it up?
Remember that the WASSP System system must acquire twice the depth of a single beam
sounder to enable the full seafloor profile across 120°. If the entire profile is to be captured, the
ping rate will need to be at least half that of a standard single beam sounder.
Manually adjusting the range down will increase the ping rate significantly but will result in the
loss of seafloor information, including break up of the 3-D display after a point. If you are only
interested in the centre beam of the triple beam display, the range control can be reduced to just
over half the current depth in metres. The optimal range is twice the current depth in metres.
The range control should normally be set to automatic (green digital display).
Other programs running at the same time as the WASSP System program consume processing
power and take processing time away from the WASSP System system, slowing down the
rate of transmission. For optimal performance, ensure the WASSP System program is the only
application running.
7.2
The system has stopped transmitting without operator
intervention. Why?
If time is taken from the system by another application for long enough, the WASSP System
may restart transmission in a number of seconds. The WASSP PC is a dedicated system and
should not be used for other applications.
If the system does not restart, try stopping and then starting the system using the MODE
button on the tool bar. If this does not work, try to restart the WASSP System program and the
transceiver. The most likely cause of this is a sudden power supply spike or drop.
7.3
When I press the Transmit button, nothing happens and there is no
activity on the WASSP display. How do I fix this?
First make the following checks of your WASSP installation:
• Check that the BTxR power is ON and the LED light on the front panel flashes every few
seconds.
• Make sure the network cable is connected at both the BTxR and the WASSP PC ends
(unplug and re-plug to make sure).
• Check that the Processing Module application is running (look for the icon in the Windows
Taskbar at the bottom of your PC screen) and was running when you started WASSP. If not,
restart the WASSP GUI after running the Processing Module application

This may be accompanied by the BTxR’s LED turning orange.
►►
F:0003: TRANSMITTER UNDER VOLTAGE SET (STATUS = %lx) (%s)
%lx => status bits from transmitter board
%s => module detecting error
This message will occur when the voltage on the transmit board has not reached the required level for a transmit ping pulse.
Is the system has been reset by another fault then the transmit board may be disabled, resulting in the under voltage error.
If this error does not get cleared (see below), check the PSU max current.
Check that it is not a secondary problem due to the BTxR resetting caused by an unrelated
event.
►►
F:0004: TRANSMITTER UNDER VOLTAGE CLR (STATUS = %lx) (%s)
%lx => status bits from transmitter board
%s => module detecting error
This is a message informing the user that the voltage of the transmit board has reached the

7.5
Why is there a ring displayed just above the seafloor? What causes
these ‘ring’ marks? How can I get rid of them?
This ring is a by-product of the multibeam technology of your WASSP system. It is supposed to
be there but in practice we want to make it as difficult to see as possible. To avoid these rings
confusing the seafloor tracking algorithms or being confused as fish marks the Minimisation
feature allows these rings to be suppressed
on the Sonar display. Care should be taken
because hiding these rings will also make it
hard to see any signals below them such as
fish on the bottom.
When a signal arrives at the receiver it
creates a shadow like effect that creates a
ring of much weaker echoes, the stronger the
signal the stronger the rings. Unfortunately
the signal return from the seafloor is many
orders of magnitude stronger than a fish
echo and thus the shadow of weaker echoes
can be comparable to fish targets.
How do I know if I have a problem then?
When running with Auto Power By Signal (BLUE) and the power level is above 1 then the
required minimisation should be 1500 or less. The lower this is the more chance of seeing fish
below the ring but the more chance of the rings being visible on the Sonar display. If you are
required to use a higher power level then it may well be impossible to hide them completely with
Minimisation.
If you have the system working with no sign of these rings and then they start to appear and you
have not changed the Minimisation settings then something has changed for the worse – keep
reading.
a) Too much power – This is the most common cause of problems. When there is too much
acoustic energy in signals returned from the seafloor they may distort. Distortion of the signals
will cause ambiguity in resolving the position and thus create rings of very high amplitude.
Unless in very shallow water Auto power by Signal mode will automatically try to select the
highest power level that doesn’t cause distortion. You may get the occasional strong return
causing faint rings, but this is good so that you have as much power as practical for detecting
fish.
b) Gain settings. This ring will appear more or less significant as the sonar gain is changed.
c) Shading of Receiver – Any difference across the receiver caused by marine growth or
any other irregularity across the face of the receiver will contribute to a reduction in the
discrimination of the WASSP system. This will lead to higher intensity rings.
d) Reconnection Fault – If the cable from the BTxR to the Transducer was disconnected and
has been reconnected recently it is possible the receiver is connected incorrectly. Check the
colour codes of Ethernet connections.
e) Calibration – It is possible that the system calibration was disrupted by another sounder,
close the WASSP GUI and re-run to allow the system to re-calibrate.
f) Electronics Failure – If one or more central channels fail in the electronics this will increase
the intensity of the ring.
g) Configuration – Changes made in the Technician configuration could significantly change the
system performance. Restart the WASSP GUI if you are unsure what state the system is in. The
Configuration Manager has a Defaults option to load your default configuration settings if all else
fails.

7.6
What is this constant signal on the sonar/single beam display?
There are many sources of noise, interference and general acoustic reflections which can make
these displays difficult to use. A description of the different types of noise and ways in which you
might be able to determine and eliminate them follows.
Sonar/Sounder – Other Sound producing devices will produce constant blips on the WASSP
sonar display which will vary in intensity and size depending on the transmission power and
angle of the system.
Aeration – Air in the water around the transducer can cause transmitted signals to be absorbed
or reflected prematurely resulting in false signal reports from the transducer.
Biomass – Large bodies of photo plankton can float through the sea covering very large areas.
This may be the source of large areas of constant faint signal return through a region of the
water column.
Own Transmission – WASSP shows all received signals starting from half way through the
transmission pulse. Thus you should see a red or yellow ring at the top of the Sonar display. As
power level and pulse width increase this signal return will be stronger and larger.
Keel Reflection – If the WASSP system is mounted in such a way that transmitted signals can
reflect off the ships hull you may find that there is a constant strong return shown on the sonar
display. This may happen even if the hull is just outside the 120 º transmission swath. If a strong
signal follows the boat and is within the dimensions of the ship then this signal is probably a
reflection off your own ship. This will make it hard to detect fish at this depth but otherwise
shouldn’t affect the performance of your WASSP system.
Electrical – There are an almost infinite number of ways in which Electrical Noise can influence
system performance. The first priority is that the system be well grounded – this means a large
and preferably short grounding wire connects the Transceiver to the Power supply ground.
WASSP is relatively protected by noise on Power supply sources but a very noisy supply could
cause trouble. More likely causes of electrical interference are if noisy, high power machinery or
wiring is run beside the transducer cable. Electrical noise is either constant, regular or transmit
power dependant.
Water Temperature Layers – A thin faint horizontal line that is present ping after ping in the
same place could be a temperature layer. The Sea is often layered with various temperature
layers due to pressure and surface mixing. Often a reflection can be created at the depth where
a significant change in water temperature occurs – causing an acoustic return.
Prop Noise – If the turbulent water flow off the props is directed onto the transducer face this
could create aeration noise. Especially relevant for lower frequency models – it may be possible
to pick up the prop noise as an acoustic source. For this reason it pays to mount the transducer
some distance from the ships props. Prop acoustic noise will appear on the side of the Sonar
display close to the prop and will look like a regular pulse or solid signal depending on the
rotation speed.
Vibration – Shudders of vibration and vibrating mounting structures can induce significant noise.
Additionally a vibration in mounting can cause motion compensation of the system to fail. Sharp
jolts and vibrations will generate rings of high signal.
7.7
Why is my WASSP System not tracking the seafloor?
Any source of noise mentioned in the answer to “7.6 What is this constant signal on the sonar/
single beam display?” above can cause the seafloor detection to fail if it is bad enough. In
some cases bad noise can cause the tracking to fail and it could take a number of pings for the
WASSP system to re-acquire the seafloor. In some instances noted below and in bad cases of
Doc. P/N: WSP-009-004
Version:V1.3
Issue Date: August 2013

Page 55 of 62
Operator Manual
noise it may not be possible to automatically resume seafloor tracking.
Power – If too much power is being used for the depth of water you are operating in, the
seafloor tracking signal could be noisy especially if there is enough power to cause signal
distortion, as the tracking algorithm may track the rings produced by this. Conversely, too low a
power level may result in the signal levels from the seafloor being below the noise floor of the
system and thus they will be ignored as noise. This will tend to cause the surface noise to be
considered as a bottom detection candidate.
Depth – The WASSP system can acquire a seafloor profile swath 3.5 times the nadir depth
but this requires the acquisition depth to be at least twice that of the maximum depth on that
swath. WASSP takes this into account so when the Depth Dial reads 100m, the system acquires
to 210m. If the acquisition depth is in manual mode or the system fails to track down with the
seafloor then you may need to manually increase the system range to allow it to re acquire the
seafloor.
GPS Position – If there is no position the WASSP system will not output depth data and will
cease to map the seafloor.
Minimisation – The seafloor tracking is affected by the Minimisation level; ensure this is set
appropriately as described in the Installation Manual.
7.8
Why doesn’t the seafloor line up when I go over it again?
There are several factors which can cause this to show on your WASSP display however
remember that if the vessel is operating in a high sea state, your motion sensor may not be able
to fully compensate for the vessel’s movement:
GPS Time Lag – Ensure that any GPS delay is entered into the Ship Setup Configuration as this
will cause large errors in depth. See section “10.2.6 Sea Trial - Commissioning Step 13 : GPS
Time Delay (Required)” on page 54 of the Installation Manual.
Motion Compensation – To make good use of motion compensation we must ensure that the
WASSP transducer and any Motion sensors are securely mounted and do not move at all. The
dynamic and static accuracy of the motion sensor effectively determines the differences you can
expect when you pass over the same area again.
Sea State – Motion Compensation is a complex process and makes some assumptions – the
bigger the sea state and the smaller the boat the less reliable the seafloor data will be as there
is more reliance on the accuracy of measurements and the input from the motion sensors.
Cornering – Motion compensation is costly to do to the nth degree. Most low end Motion
sensors have poor performance on corners due to the centripetal acceleration forces caused by
a turn affecting the delicate balance of the sensor. Thus seafloor detections collected while the
boat is turning are likely to be of lesser quality than those collected in a straight line.
Water Temperature – The water temperature and salinity affect the sound speed and thus the
angle at which the sound moves through the water column. This causes the seafloor to curve
up or down as noted in the operator manual. If the seafloor exhibits a curve up or down on the
edges, adjust the sound speed. Note: The surface water temperature will probably change
during the course of a day.
Tide Correction – Tide is essential for matching up overlapping swaths. If you have disabled
the Tide correction the swaths will rarely line up on your WASSP displays. Ensure that the ZDA
sentence is being collected and sent to the WASSP computer so it can determine the UTC time
and use the correct tide correction value.
Transducer Offsets – The transducer, GPS and draft offsets need to be input into the WASSP
ship setup configuration so that the motion induced errors in the seafloor can be correctly

compensated for.
Roll Offset – If there is a fixed offset in the mounting of the transducer or Motion Sensor you will
need to conduct a patch test to determine this error. Without this the roll correction will not work
correctly.
7.9
Why does the seafloor move if the system is Motion Compensated?
The views are only compensated for Roll to save on processing time and to avoid creating
artefacts in the data. If the Sonar display is rotating then the Roll correction is not working.
Remember too that if the vessel is operating in a high sea state, your motion sensor may not be
able to fully compensate for the vessel’s movement.

show Current Values for NMEA data if
configured to receive it.
Check that the device that you receive
roll information from is ON and that all
your serial cables are still connected to
your WASSP computer.
Check that the correct sensors are
selected in the NMEA tab of the Ship
Setup Options - this configuration could
have been inadvertently changed.
Check that the Roll Correction settings
have not been changed under Ship
Setup Options - Sensor Values tab.
If the transducer has been re-installed,
the Swap Array setting could have
changed in which case you will need to
invert the Swap Array setting.
If the roll offset is incorrect, a slight roll
of the display will occur.
If the Swap Roll setting is incorrect you
will see a doubling of the actual vessel
roll (i.e. the roll received when Roll
Correct is disabled).

►►
Verify that the Transfer Task is receiving data on each activated port by checking that the
Activity light flashes green (not red). The Transfer Task can be found in the Windows Task
Bar. You can verify that the correct NMEA sentences are arriving on each port by selecting
‘Monitor’. This will print out the received NMEA onto the window for that particular port.
►►
Finally if the seafloor is not uniformly flat you could see rapid changes in the sonar display
with each ping as the ship moves across the seafloor. As there is no heave or pitch
compensation on this display it will often move up and down and if the seafloor changes
angle it will also appear to roll a bit. If you are unsure, check that the seafloor remains flat on
a flat section of seafloor and remember that a vertical shift is expected if there is vessel roll,
pitch and/or heave.
7.10 The mode button animates as if pinging but nothing happens.
What is wrong?
Check your GPS is on. This can be validated by checking the network input screen or transfer
task diagnostic displays.
Increase the gain, and range. Can you see noise on the Sonar Display? If not, reset the power
to the Transceiver, and reset the PC and retry. If this problem persists and there are no error
messages, contact your dealer. If you are getting an error message or messages, look at the
relevant information for the error message in the section of the FAQ.
Ensure that the Transducer has not been disconnected from the BTxR, both the receiver cables
and the transmit cables need to be connected in order for the WASSP system to operate. If
problems persist after a full system shutdown and power up then contact your dealer.
