Operator Manual

1. Introduction

1.1 Purpose of this Operator Manual

This Operator Manual contains instructions and information on the operation of the software package supplied with your WMB-X230 (i.e. WMB-3230 or WMB-5230) system. Installation and Commissioning procedures are contained within the Installation Manual, also supplied alongside this manual.

Please refer to the Installation Manual for instructions on transducer and BTxR installation, sensor connection, system conﬁguration and setup, and commissioning steps required to get your WASSP system up and running.

1.2 Introducing the WASSP Sonar System

The WMB-X230 is a multi-beam 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 multi-beam sonar and 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 and wrecks, ﬁsh schools, seaﬂoor hardness changes, and foreign objects in the water column or on the seaﬂoor. From the 120° swath, the system processes 112 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 intuitive graphical user interface displays both acoustic views and charting views for complete knowledge of the world beneath with the ability to view both real-time and previously recorded maps from any part of the globe in 2D and 3D. Depth and backscatter colours can be dynamically changed while viewing. The system can output data to plotting software packages. For optimal performance, roll, heave, pitch, heading and position inputs are all required.

The WMB-X230 can be applied to a variety of ﬁshing methods, as well as search and rescue, customs, and police applications.

1.3 Main Features

The WMB-X230 has the following main features:

► Improved performance.

The use of separate transmit and receive arrays has enabled WASSP to optimise both transmit performance and receive sensitivity, giving improved performance over traditional sonar and sounders.

► High detail picture of 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.

► Real-time map generation.

Generate new maps in real-time from bottom detections.

► Beam stabilisation.

Beam stabilisation compensates for the movement of the vessel, providing accurate seaﬂoor proﬁles and ﬁsh school locations.

► Variable beam width.

Unique to the WMB-X230 the single beam view can not only be stabilised, but the beam width can be varied from 5° to 40°.

► Triple beam view.

With variable width and angle, the port, centre, and starboard beams display together to help build your understanding of the sea environment.

► Navionics chart overlay.

The charting displays can draw a vector Navionics hydrographic chart overlaid on the WASSP seaﬂoor data. The displayed chart features can be turned on or o as required. Maps are available from

Doc. P/N: WSP-009-008 Version: V1.3 Issue Date: April 2014

www.wassp.com

Navionics to cover almost every part of the world.

► Bottom lock.

Bottom lock provides a traditional bottom lock mode where the changes in bottom depth are ignored and the bottom is drawn ﬂat. Fish and other echoes are shown relative to the ﬂat bottom image, enabling better discrimination between bottom ﬁsh and the seaﬂoor.

► Computer based proﬁle storage.

A computer-based system means the WMB-X230 can generate and store very detailed seaﬂoor proﬁles.

► Map resolution based on depth.

Your WASSP system dynamically changes the resolution of the stored maps to suit the depth of the seaﬂoor. Shallow seaﬂoor data is stored at resolutions as high as 250mm to give the maximum detail available, while deep seaﬂoors have their resolution restricted to 4m to avoid saving spurious ﬁne detail.

► Database management.

The WASSP system uses one or more databases for storing and displaying WASSP data including the depth, backscatter and water column information. Additional databases can be created at any time and incoming data can be assigned to any database. Unnecessarily large databases can be downsized to save recording space.

► Digital signal processing (DSP).

Using DSP technology, the WMB-X230 can provide an indication of changes in seaﬂoor hardness, ideal for scalloping, crayﬁshing, and trawling where you want to understand and locate small changes on the seaﬂoor.

► 160 kHz operating frequency (WMB-3230).

Operating at a frequency of 160 kHz provides high seaﬂoor deﬁnition at depths down to 200m.

► 80 kHz operating frequency (WMB-5230).

This frequency provides performance down to 500m with a slight reduction in the shallow water < 60m performance.

► Depth and seaﬂoor coverage.

Seaﬂoor coverage is determined by the beamwidth in use: For a 90 degree beamwidth, the seaﬂoor coverage will be approximately twice the water depth. For example, 100m depth gives 200m seaﬂoor coverage with 112 beams - every ping. For a 120 degree beamwidth, the seaﬂoor coverage is 3.4 x depth. For example 200m depth gives approximately 680m 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.

► More accurate seaﬂoor - faster.

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 software features are developed.

2.9 Snapshots Button

Clicking this button creates a snapshot of ≈1000 pings of a selected area.

See “7.6 Snapshots Tab” on page 55 for detailed procedures on how to play snapshot ﬁles.

2.10 Mapping Options

Used for interfacing seaﬂoor and water column data to chart displays (see “4. Chart Display Modes” on page

18) and external viewers. This is useful for users who are recording to a database, but want to stop recording temporarily, as the interfacing is an easy toggle ON / OFF. Both WASSP seaﬂoor data and watercolumn targets can be toggled.

These options only aect database recording for the Charting display, and will not stop raw data recording.

This button toggles seaﬂoor detection recording for the Chart displays. When enabled, the seaﬂoor data as detected by the pinging transducer will be saved to the current recording database.

When disabled, the charting display will not record the seaﬂoor data detected by the WASSP sonar.

See “6.9 Database Manager” on page 41 for more information on recording databases.

This button toggles 3D ﬁsh marks recording for the Chart displays. When enabled, 3D ﬁsh mark information from the pinging transducer will be recorded for use on the charting display. When disabled, 3D ﬁsh marks will not be recorded for use on the charting displays.

You may nd that operating in conditions that restrict good seaoor return (such as deep water) doesn’t allow water column detections such as sh to be passed through to the charting displays. You will nd an override for this (to pass ALL detections) under section “7.1.4 System” on page 46.

2.11 Utility Panel Button

This button brings up the Utility Panel, which is a quick-access panel for frequently used options and displays.

The Utility Panel is also the place for modifying ship settings and conﬁgurations, under the System tab.

3. Acoustic Display Modes

The WMB-X230 graphical user interface has three acoustic display modes and two chart display modes. These display modes all show acquired data in dierent ways, with various settings available for adjusting each type of display.

Each of these display modes can be viewed in multiple dierent layout conﬁgurations. For information on conﬁguring dierent display layouts, see section “5. Layout Selection” on page 32.

► Each acoustic display can be zoomed by using the mouse wheel - just click on the display and

scroll up or down to zoom in or out.

► The zoom on each acoustic display can be reset by double-clicking on the window.

The following display modes make up the acoustic feature of the WASSP software.

3.1 Sonar Display

The sonar display 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 4.

A 120° wide by 4° long swath or footprint is covered. The system generates 112 beams over the 120° footprint to provide a high-resolution sonar view. 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).

3.2 Single / Triple Beam Display

The Single / Triple Beam Display shows seaﬂoor and water column information in a similar fashion to the traditional ﬁsh-ﬁnder display. Signal returns are drawn vertically in slices, with new information appearing on the right of the display, and old information dropping o the left side.

In Single Beam mode, only the middle beam is used to draw the information from the seaﬂoor.

In Triple Beam mode, additional port and starboard beams are used to draw information from selectable areas of the water column through conﬁguration of the beam width and beam angle. See Figure 5.

This button opens up the Options for the Single / Triple Beam Display.

Overlays a grid on top of the Single / Triple Beam display, to enable the user to quickly judge distances to targets.

This adjusts the angle which the centres of the port and starboard beams are set from the middle beam. Larger angles move the beams further from the middle beam, and smaller angles move the port and starboard beams closer to the middle beam. The beam angle can be set to 5, 10, 15, 20, 30, or 40°.

This adjusts the width of the three individual beams used for the Single / Triple Beam Display, and can be set to 5, 10, 15, 20, 30, or 40° widths. Selecting a 10° beam width with a 20° triple beam angle will therefore give a 50° swath for the Triple Beam view. See Figure 6.

This is the method used by the program to constantly display the seaﬂoor during scanning operations regardless of the changes in seaﬂoor depth. This is indicated by the word (Tracking) being tagged to the end of the words Manual Zoom in the Text Box when the text box Status option is enabled.

Seaﬂoor Tracking must be enabled in the Conﬁg sub-menu and the Range Control dial set to automatic (GREEN). If Seaﬂoor Tracking is disabled in the conﬁg sub-menu, the word (Tracking) disappears from the Text Box. If the Range Control setting is in manual mode (YELLOW) and the seaﬂoor then drops below the range setting, the seaﬂoor will stop being tracked (and lost from the screen).

This button enables the Triple Beam display. Triple Beam orientation can be changed between Horizontal and Vertical in the System Tab of the System Conﬁguration Utility (see “7.1.4 System” on page

3.2.2 Display Oset (Shifting)

Zooming the Single / Triple Beam Display, by default, is centred toward the transducer location (0 m depth), but the focus of the display can be changed by using a display oset.

With the Bottom Lock mode disabled, left-click on the Single / Triple Beam Display window and keep holding down the left mouse button. By scrolling the mouse wheel, the zoom centre on the Single / Triple Beam Display can be shifted from 0 metres depth (centred on the transducer), to deeper down the water column.

Note: Right-click at a point on the Single / Triple Beam display to send a mark to the Charting display at the cursor location.

Advantages

Ã Shows past information. Ã Width and colours of seaﬂoor return can be used to help determine

bottom types.

Ã Adjustable beam width allows optimisation for full coverage or high

resolution to see small detail changes.

Ã Display redraws dynamically when range, gain, or zoom change.

Disadvantages

Ä Harder to relate the location of features seen to the vessel’s position. Ä Does not show all information seen by the sonar view.

3.3 Sidescan Display

The sidescan display is another display type for viewing information generated from 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 o the bottom of the screen. This is similar to the way the Single / Triple Beam Display operates, except that in their case, the new data appears on the right and the old data disappears o the left of the display.

The left side of the Sidescan Display 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.

The primary advantage of the sidescan view over the other views is in locating and identifying objects on the seaﬂoor o to each side of the vessel. Some structures such as a shipwreck may appear like a large ﬁsh school on the sonar view and thus not appear as an object on the other acoustic or chart displays. Figure 7 shows how a wreck sitting on the seaﬂoor can be distinguished as a clearly shaped structure by using the Sidescan Display, allowing the user to interpret the sonar information from a dierent viewpoint.

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.

3.4 Fish Options

The Fish Options window contains preferences for watercolumn target detection. The user is able to select any depth range and threshold for target detections, and view a detection histogram with an adjustable 30 minute history. The settings contained in this window aect both the 2D and 3D ﬁsh shown on the charting displays (NB: the 2D ﬁsh will ignore the history setting).

3.4.1 Fish Display Options

► Between Depths: The user can set a depth range for watercolumn

detections. The WASSP program will ignore detections outside of this range.

► From Seaﬂoor: If the user is only interested in near-bottom targets,

the From Seaﬂoor option will only use detections that are located a certain distance above the seaﬂoor, ignoring the rest of the water column. If Bottom Lock is enabled (see “Bottom Lock” on page

12), the Single / Triple Beam display will show a green line where the detections start.

► From Range: If the user has set detections to “All Targets in Ping”

(see “System” on page 46), then the “From Seaﬂoor” setting becomes “From Range”. In this case, users are generally working in deep water without a discernable seaﬂoor. The detection range will be from the last signal acquired up the water column. The depth of the last signal will depend on the setting of the range dial.

3.4.2 Fish Threshold

Generally speaking, large ﬁsh return a stronger signal than small ﬁsh. The Fish Threshold control dial allows you to tune the “Fish Detection” for your vessel. The control has a range of 1 to 30. It is recommended that this threshold is set high enough that only the desired targets are ‘detected’. This control also aects the ﬁsh shown on the charting displays as well as the Fish Histogram.

3.4.3 Fish Histogram

The histogram shows a gain-adjusted colour table to help reference the Fish Threshold to normalised signals on the Sonar and Single / Triple Beam displays. The Fish Threshold setting is visible as a white line on the colour table. By adjusting the Fish Threshold and referring to the histogram, you will ﬁnd an optimum level for your vessel’s installation.

3.4.4 Detection Mode

WMB-X230 oers two modes for ﬁsh detection (Mode 1 and Mode 2). Both modes detect ﬁsh, but vary slightly in their approach.

Seaﬂoor discrimination settings will adjust how detections occur on outer beams. When discrimination is set to none, the detection algorithm will try to detect targets as close to the seaﬂoor as possible, but may incorrectly identify part of the seaﬂoor return as targets. When discrimination is set high, the detection algorithm will try to ignore targets close to the seaﬂoor in case they are part of the seaﬂoor return. Medium discrimination is a balance between the two.

Clicking this button to open the Advanced Options. Conﬁgure these functions to best suit your requirements.

The suggested values for the Advanced Options are:

► Minimisation: 4000 (or 800 if using auto power by signal).

► Clutter: 0-500.

► Mapping Beamwidth: 0,0 (Full 120 degree beam width).

► Interference Filter: Enabled (High) if another sounder is transmitting.

► Noise Filter Disabled (only enable if interference issues present).

Operator Manual

Utility Panel

minimisatiOn

clutter

BeamWidth reductiOn

Minimisation describes the ﬁltering process used to remove sidelobe signals. Sidelobe generated signals show up as a ring on the sonar view where the transmission pulse ﬁrst strikes the seaﬂoor, or as a mirror of features on either port or starboard.

Sidelobe generated features can confuse the sonar picture making it hard to interpret. However, too much minimisation can also distort the sonar image. Refer to section “8.2.3 Sea Trial - Commissioning Step 10: Side Lobe Levels” on page 49 of the WMB-X230 Installation Manual for more information on selecting correct minimisation settings for your installation.

Clutter describes the ﬁltering process used to remove all signals below a threshold level from the sonar and ﬁsh ﬁnder displays. The control sets the threshold for the minimum signal level that will be displayed on these displays. This control is dynamic and does not aect any other aspect of the system including the contour ﬁsh detection!

Mapping Beamwidth sets how far apart seaﬂoor detection points are calculated. Port = 0 and Starboard = 0 means detections are processed for 120º of the 120º swath. Port = 10 and Starboard = 10 means detections are processed for 100º of the 120º swath.

interference filter

Doc. P/N: WSP-009-008 Version: V1.3 Issue Date: April 2014

The default value for Mapping Beamwidth is 10 beams from port and starboard. Set this value to 0 for both Port and Starboard to get the maximum seaﬂoor mapping width. Sound speed errors and signiﬁcant ship motion will make mapping correctly with these outer beams more dicult.

The Interference Filter enables a reduction in interference caused by other ultrasonic sub-sea acoustic devices such as sounders. It also provides some noise ﬁltering. It is recommended that the interference ﬁlter be left selected (Enabled) if you have another sounder or sonar on your vessel that operates at the same time as the WMB-X230. Best results are achieved if all other sounders are turned o. Set the Interference Filter Level to High when encountering strong interference, and Low when interference is weak.

tx pulse BlankinG

nOise filter

sinGle Beam if

This will remove noise which is constant across the sonar display, such as transmit pulses from other acoustic sounder equipment. Works just with the sonar display and single beam display.

It is best to start the slider from the right hand side and move to the left until you see less interfering pulses on the sonar display.

This ﬁlter will also remove bottom detections which intersect with interfering pulses.

This Filter is used to remove low level electronic white noise from inﬂuencing the sonar. Unlike Clutter this setting eects all processing and changing this value will not update all previous ﬁsh ﬁnder history.

The Noise Filter is designed to helping clean up the Sonar and Fish Finder Views and to prevent low level noise amplifying up with TVG and standard Gain to confuse the sonar and ﬁsh ﬁnder displays.

This is a ﬁlter just for the single beam display. It will remove interfering pulses from the sonar data.

NOTE: this will leave holes where these pulses occurred.

LOW = remove large pulses MED = remove large & medium pulses HIGH = remove large, medium and small pulses

6.4 Rescan

The Rescan button rescans for Navionics chart cards and WASSP dongles.

If you want to change the WASSP dongle or Navionics chart while the program is running,

remove the dongle or chart and insert a new one, then click the Rescan button. The program rescans the dongle and should read the new one you have inserted. See “9. Navionics Chart Card Information” on page 62 of the Installation Manual for more information on registering Navionics chart cards.

While in the Demo mode, the system does not need network connections to operate correctly as data ﬁles are played back through the program.

kp (key pulse) settinGs

The key pulse functions are presented as an option to improve WASSP performance when operating alongside other sonar systems. WASSP will always output a Key Pulse through the ping gate when it transmits.

To make use of this functionality, the KP connections on the front plate must be in use. See “4.2.2.3 Key Pulse Connection” on page 19 of the Installation Manual for connection details. To determine if the Key Pulse is being detected by the BTxR, refer to “6.7.1.1 Key Pulse Graph” on page 39.

► Master Mode: Use this if there is no key pulse from other sounders. ► Slave Mode: Use this to only ping when another sounder (with key pulse wired into input of

BTxR) pings. If the sounder is o, WASSP will eventually time out, and only sync to this device once key pulses are detected again).

► Rx Blanking: Use this setting to allow WASSP to ping at its native rate, but to blank out any data

received during the key pulse interval received at the BTxR key pulse input. Removing data can cause issues with tracking, but maintains the maximum ping rate on both systems.

► Hybrid Mode: This mode automatically detects the key pulse device ping rate to optimise

the choice between Rx Blanking (above) and Slave Mode (above). This option ﬁnds a balance between the least interference and best ping rate.

6.7.1.1 Key Pulse Graph

The Key Pulse Graph shows the state of the input key pulse according to how the WASSP system has interpreted it. The WASSP detects changes between input states, and draws those on the graph at the point of the ping time where the state change is detected.

When enabled, the KP Graph replaces the “I” data stream on the IQ Raw Data tab, and is the same regardless of the selected channel.

Ensure the input key pulse from the secondary sounder has

been correctly installed according to the pin conguration on

page 19 of the WMB-X230 Installation Manual.

Note: The KP Graph is not an oscilloscope. It will not show the raw KP voltage. The graph is only indicative of key pulse state changes detected during the WASSP data acquisition time, and may not draw pulses less than 0.3ms in width. The polarity drawn on the graph may not correspond to the input polarity.

Figure 19 shows an example where the WASSP is operating in Slave Mode. The ﬁrst key pulse visible has triggered the WASSP system to ping and collect data.

During the data collection, a second key pulse was detected, but this did not trigger another ping, as the WASSP system was still acquiring data. The WASSP system will wait until the next key pulse after data acquisition for the current ping has ﬁnished before pinging again.

Figure 20 shows an example of the WASSP system operating in

Master Mode or Rx Blanking Mode. Here, the WASSP system

is pinging at its native rate, ignoring the input key pulse. The WASSP ping is not synchronised with the input key pulse.

6.9 Database Manager

The charting display stores and displays the WASSP information in databases. Each database can store information from any geographic area or areas. The areas do not have to be co-located or continuous but can cover dierent parts of the globe if desired.

The Database File Path must be set to the directory in which the databases are created. Additional databases can be created by clicking on the “New” button.

The databases allow the operator to store WASSP information from one or more visits to an area. This allows changes between the visits to be easily compared. A database may however be overwritten by selecting it for writing on a subsequent visit.

The Database Manager provides an ability to select both a “Viewing” and a “Recording” database. The information displayed on the chart display is always taken from the “Viewing” database. Incoming data from the WASSP is always written to the “Recording” database. To view incoming seaﬂoor data as the WASSP collects it (normal operation), set the Viewing database to the same as the Recording database. By selecting a dierent database for “Viewing” than “Recording”, the operator is able to look at the information previously recorded while still saving to the recording database.

To add a new database, click on the “NEW” button at the bottom right of the Database Manager window. The following prompt will appear.

Enter a name for the database, select a Map Grid Size (see below), then click “OK” to create the new database.

The new database will show up on both the Viewing and Recording side of the Database Manager window. The database ﬁles are sorted by name so the database may not show up at the bottom of the list. If you plan to record to the new database, make sure it is

selected as the active Recording database.

map Grid siZe:

This is used to set the resolution of the seaﬂoor maps. The smaller the grid size, the greater the resolution and accuracy of the seaﬂoor data.

► 0.25 m (applicable for the ﬁrst 40m) is the highest resolution, and the best option for accurate

seaﬂoor mapping.

► 0.5 m (applicable for the ﬁrst 100m) is a good compromise between saving hard-drive space and

recording semi-accurate seaﬂoor data.

► 1.0 m (applicable for the ﬁrst 250m) is the least accurate selection for mapping seaﬂoor data, but

is the most economic selection in terms of saving hard drive space. This is the recommended setting for ﬁshing purposes, as 3D ﬁsh marks are unaected by the choice of database grid size.

Because the database will be created as a new folder on the WASSP Processor, it is best to use plain text and numbers as some characters cannot be used.

Beyond the above applicable depths, the next map grid size will be used to store seaﬂoor data. This eliminates unnecessary precision at larger depths.

6.11 Day/Night Mode

By default, the WASSP program runs in Day Mode. This means that the user interface and all windows are shown with normal brightness as required during day time or bright ambient light conditions.

If the WASSP program is being used during the night time or in reduced lighting conditions, the user may ﬁnd it more comfortable to use Night Mode. Night Mode darkens the entire user interface so that the user is able to use the program in a darkened wheelhouse without having to allow time for the eyes to adjust to a bright screen.

The Day/Night Mode icon is used to toggle Day Mode (normal operation) and Night Mode.

The brightness of the user interface while Night Mode is enabled can be set in the System Tab of the System Conﬁguration (see page 46). The selectable Night Mode brightness value ranges from 10% (darkest) to 90% (brightest).

Adjusting the display brightness on the monitor you are using can also be used to reduce / increase the screen brightness.

7.2.1 General

General settings provide:

► Vessel Information: Vessel’s name, country and home port may optionally be entered here. This

will be recorded inside any raw data recordings.

► WASSP Hardware Settings: The Transducer Serial Number and BTxR Serial Number are ﬁlled in at

time of installation. These should not be changed by an operator. The BTxR Versions are reported from the BTxR for diagnostic purposes.

► Device Settings: The three sensor types required for accurate proﬁling can be selected from

drop down lists. Select the appropriate installed sensor for each of the sensor types. The advantages of having correctly selected sensors are that you can compensate for pitch (and possibly heave) as well. To make corrections using the SC30’s Pitch, Roll and Heave values, select the appropriate check boxes.

7.2.2 Osets

Osets are conﬁgured during the installation and commissioning of the WASSP system. See “8.1.1 Commissioning Step 1: Ship Measurements” on page 37 of the Installation Manual for more information.

► Transducer Heave Compensation: This check box should be selected if the X, Y, and Z osets

have been recorded AND a motion sensor is conﬁgured. This settings enables the system to compensate for relative heave at dierent points on the vessel generated by the vessel pitching and rolling.

7.2.3 Sound Speed

The Sound Speed sub-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 calculated from temperature given a Salinity value.

7.2.4 Sensor

The Sensor tab provides a selection of motion compensation options and corrections for sensor misalignment and time delay. These settings should not be changed by the operator outside of the commissioning process.

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 reasonably ﬂat 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.

The settings on the Sensor sub-tab require an understanding of the motion sensors equipped and carrying out a series of

procedures covered in section “6. Sensors” on page 28 of the Installation Manual.

headinG and pitch Offsets

The Heading and Pitch Osets will correct for transducer and motion sensor misalignment.

Gps time delay

All GPS positioning systems have some delay from receipt of the satellite signal to output of the correction data. When a Furuno SC-30 is used as the source of position data, this delay is approximately

1.0 seconds and equates to an error of 5m in the location of an object on the seaﬂoor at 10 knots. This value should only be changed post-commissioning if the type of position sensor or its conﬁguration is changed.

mOtiOn delay

The motion delay value is displayed for information only and cannot be changed. The value is determined by the type of motion sensor selected in the General Tab of the Ship Setup.

7.2.5 Power

The WMB-3230 (5230) BTxR can output 14 (16) dierent power levels, 7 in the low range and 7 (9) in the high range. Each power level has a corresponding pulse width which is automatically applied.

The type of power control can be selected from three methods:

► Manual Power: The output power level is selected

manually using the Power Controls on the Main Menu (see “Power Level Control” on page 7)

► Auto Power by Depth: The output power level is

determined by the current depth. The depth ranges are selectable from 14 drop-down boxes. A Defaults button resets all fourteen power levels to a default setting. When setting power level depth settings individually, click the Apply button after setting the levels.

► Auto Power by Signal: The output power level is set according to the maximum acoustic echo

received (normally the seaﬂoor). The received level is set to prevent saturation of the receiver. This option should provide the best overall system performance.

Note: There are TWO different Automatic Power modes. Automatic Power by Signal AND Automatic Power

by Depth. Automatic Power by Signal is better for seaoor mapping and seeing sh out on the sides near the seaoor. Automatic power by Depth is useful to detect smaller sh easier at the cost of seaoor detection.

To switch between Manual and Automatic Power, double click on the LED Power Level indicator on the Main Menu.

Doc. P/N: WSP-009-008 Version: V1.3 Issue Date: April 2014

www.wassp.com

If a power level is set out of sequence, for example level 5 is set to 40 m, level 6 is 70 m and level 7 is 60 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. See Figure 29.

► Absorption 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 set at the time of installation, and is used when calculating backscatter. For the WMB-3230 system, a default value of 40dB/km is used. For the WMB-5230 system, a default of 25dB/km is used. This value should not be changed without a clear understanding of the absorption properties of the water in the area you are working in.

The ﬁsh overlay on the 2D charting display can be drawn in two dierent ways:

► Fish 2D Data: Fish detections are drawn on top of the seaﬂoor image. The

colour on the overlay is dependant on the number of detections.

► Fish 3D Data: This is a ﬂattened view of how the ﬁsh appear on the 3D display.

The colour of the ﬁsh detections is based on the intensity of return.

See “Show 2D Fish” on page 23 for information on how to enable the 2D Fish.

This controls how long 3D ﬁsh marks are displayed. Options range from 10 seconds to 24 hours, or ALL (default). See “3D Fish” on page 32 for more information.

► Mode: The user can toggle whether tracking points are drawn when the vessel

has covered a certain distance, or when a certain amount of time has passed since the last tracking point.

► Thickness: This changes how thick the vessel track is drawn. ► Distance / Time: Depending on the Vessel Track Mode setting, these settings

inﬂuence how far apart each tracking point is drawn.

► Colour: This changes the colour of the vessel track.

This option sets the interval of the contour lines drawn through the WASSP seaﬂoor data when Contour mode is enabled. See “Contour Lines” on page 24.

When the backscatter overlay is enabled on the 2D display, this will show lighting changes due to slopes if enabled.

This allows the user to select the colour the seaﬂoor will appear in monochrome mode. The seaﬂoor will be rendered in this colour with shading. It is useful for when the 3D water column information is being shown.

► Best Beam:

This stops less accurate points from the outside beams overwriting the more accurate points from the inside beams.

► Overwrite All:

All existing map points are overwritten with new points as they are received.

► Enable Noise Filter:

When enabled, this ﬁlter will reduce the noisy points which occur when the detection line mis-tracks the seaﬂoor.

These options apply slight changes to the seaﬂoor tracking algorithm.

► Shallow Bias - When enabled, this option will always choose the shallowest

point from a range of points where there is tracking ambiguity.

These options apply to the construction of the seaﬂoor mapping data into a surface.

► Low smoothing will draw more raw data but is unlikely to match up as well. ► High smoothing should reduce the eects of noise and mapping errors.

7.5 Layout Tab

The user interface of the WASSP program is very customisable. Seven (7) acoustic display layouts and four (4) charting display layouts are available to customise to the user’s preference. Each preset has been pre-conﬁgured at installation to provide a range of options for the user; however, modifying the presets to the user’s preference is both easy and encouraged. The Acoustic and Chart displays can each be conﬁgured to present dierent displays in a variety of arrangements:

Single Display Vertical Split Horizontal Split

3-Way Split

tO cOnfiGure the display layOuts:

Select the preset you want to conﬁgure.

Select what display layout you want. The available options can be cycled through by clicking

the selected layout button until the desired layout is displayed in the middle.

Now that layout you selected in Step 1 (Sonar 1-7 or Chart 1-4) is stored as part of the conﬁguration, and can be activated by cycling through the Acoustic or Chart Layout buttons on the Main Menu. See “2.7 Layout Selection” on page 7 for more information.

Move on to the next preset if you so wish to conﬁgure another layout (Step 1).

Layout arrangements can be restored to the default

settings by clicking the ‘Restore Defaults’ button in the bottom right-hand corner of the window.

Operator Manual

Frequently Asked Questions (FAQs)

9.1 The system is transmitting too slowly, how can I speed it up?

Remember that the WASSP system must acquire twice the depth of standard sounders 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 dial will increase the ping rate signiﬁcantly but will result in the loss of seaﬂoor information, including break up of the seaﬂoor data on the charting 3D display after a point. If you are only interested in the centre beam of the Triple Beam display, the range dial can be manually reduced to just over half the current depth in metres. The optimal range is twice the current depth in metres. The range dial should normally be set to automatic (green digital display).

Other programs running at the same time as the WASSP program consume processing power and take processing time away from the WASSP system, slowing down the rate of transmission. For optimal performance, ensure WASSP programs are the only applications running.

9.2 Why does the range not change on the display when I move the Range Dial?

Double-click each acoustic viewing mode (Sonar, Single / Triple Beam, Sidescan displays) to reset the view so that automatic range control is re-enabled. The range continues to track the range dial while in this mode. If any zooming is done with the wheel mouse then automatic range control will be disabled again until you once again double-click on the appropriate view.

9.3 Why is no seaoor prole generated on the charting displays after the system initially starts transmitting?

Check that the NMEA data input is being received and that the communications ports are conﬁgured correctly. If the range for data collection is too small, the system cannot acquire the seaﬂoor and cannot track the range automatically. Enter the manual range mode and set the range deep enough to acquire the seaﬂoor before returning to the automatic range mode. Also check that seaﬂoor mapping is enabled (see “2.10 Mapping Options” on page 8).

9.4 Why do gaps appear between the swath footprints on the charting displays?

There are multiple possibilities here:

► The vessel may be travelling too fast to map the seaﬂoor in this depth of water.

► The range setting could be set much larger than necessary and as a result the system is

transmitting slower than is optimal.

► The WASSP Processor is giving processing power to another operation (other than the WASSP

program) causing processing of sounding information to take longer, resulting in a slowed transmission rate of the WASSP system.

► The GPS data has come in at irregular intervals.

► The WASSP system has stopped. See Question 9.5.

► The GPS data source may have dropped out completely, preventing the system from mapping

the seaﬂoor data to its appropriate location. Ensure an isolation device is being used to convert the current loop NMEA to RS-232.

► The seaﬂoor detection may have brieﬂy failed due to aeration or excess noise.

9.5 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. If the system does not restart, try stopping and then starting the system using the MODE button on the Main Menu. If this does not work, try to restart the WASSP program and the BTxR. The most likely cause of this is a sudden power supply spike or drop.

9.6 When I click the MODE button, or run a replay (demo) le I get no picture on the display. Why?

The WASSP program is designed to run in 32-bit colour, with a minimum 1024x768 resolution. Check your display settings and change if required.

9.7 When I press the MODE button, the button goes red and a number on it counts up, but there is no activity on the WASSP display. How do I x 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 has lit up either GREEN or RED.

Make sure the CAT5 network cable is connected at both the BTxR and the WASSP Processor ends (unplug and re-plug to make sure).

Check that the Transfer Task application is running (look for the icon on the Start Bar at the bottom of your monitor) and was running when you started WASSP. If not, restart WASSP after running the Transfer Task application.

9.8 What does the error message that appears when I run WASSP mean? Is my WASSP system faulty?

Consult the list below for the cause/course of action if an error message is displayed in WASSP.

► Cannot Find Tide TCD File

Use the tide function to search for a valid database ﬁle.

Check ﬁle is present in directory. Reinstall if not present.

► Error Loading TVG File

Check in the Windows Control Panel under Regional and Language Options,

Regional Options, Customize, Numbers Tab, that the “Decimal Symbol” setting is set to a ‘.’ rather than a ‘,’ (comma)

Check ﬁle is present in directory. Reinstall if unable to locate.

► “Too Many Files With This Name. Aborted.”

This occurs when storing raw data using the data recorder if there are more than 1000 ﬁles of the same initial name in a directory. Change the name or directory if you wish to continue to save raw data ﬁles. NOTE: Unless you require the raw data for some purpose it is not recommended to record raw data ﬁles – these ﬁles are very large (≈ 2Gb/hour) and will require careful management in order to prevent the Hard disk drive of your WASSP Processor from becoming full. A WASSP Processor with a full disk drive becomes unusable. Try to have at least 10 GB of free drive space at all times to allow sucient room for system ﬁle management.

Frequently Asked Questions (FAQs)

► Cannot set power levels. Power Level x invalid.

This occurs when setting the power level settings when the depth values do not increase as the power levels increase. Check that every depth selection for each sequential power level is greater than the previous.

► No Dongle Found In System. Please Plug Dongle In And Try Again.

This error can occur if the USB device has not been detected by windows or the Dongle is not connected to the system. Remove the dongle if it is already in place and then reconnect it to the WASSP Processor after a few seconds. Press the retry button. The system will operate in replay mode without a WASSPDONGLE but will not work in real time.

► This dongle does not support the WMB-X230 system.

This error will occur if the current WASSP dongle is not licensed to run a WMB-X230 system. Contact your dealer to acquire an appropriate WASSP dongle.

► No License File Found On Dongle.

The most likely cause of this error is that the WASSP dongle has been modiﬁed or the contents have become corrupted. If the license ﬁle has been removed from the dongle the system will not operate.

Contact your dealer to source a new WASSPDONGLE – you will need to return your current faulty Dongle.

► License File Is Corrupted.

The licence ﬁle on the WASSPDONGLE has been modiﬁed in some way and is no longer valid. Contact your dealer to source a new WASSPDONGLE – you will need to return your current faulty Dongle.

► No Attitude: No Pitch.

The system is conﬁgured to compensate for Pitch and there has been a gap of multiple pings where there was no Pitch data received. Check the Motion Sensor conﬁguration in WASSP. Also check the Serial Port conﬁguration in the WASSP Transfer Task and ﬁnally that the sensor itself is on and operating correctly.

► No Attitude: No Heave.

The system is conﬁgured to compensate for Heave and there has been a gap of multiple pings where there was no Heave data received. Check the Motion Sensor conﬁguration in WASSP. Also check the Serial Port conﬁguration in the WASSP Transfer Task and ﬁnally that the sensor itself is on and operating correctly.

► No Attitude: No Roll.

The system is conﬁgured to compensate for Roll and there has been a gap of multiple pings where there was no Roll data received. Check the Motion Sensor conﬁguration in WASSP. Also check the Serial Port conﬁguration in the WASSP Transfer Task and ﬁnally that the sensor itself is on and operating correctly.

► TX PWR ERROR

This warning informs the operator that the Transmitter did not reach full voltage during the system start up sequence - the most common cause for this is a low 24V power supply voltage/current. If the system appears to operate correctly after you see this message then this is not an issue. If the system does not appear to function then the error implies that the BTxR Transmitter unit has failed - Contact your Dealer for further assistance.

► System Initialisation Failure

This error implies that the system was not fully operational when the WASSP GUI was run. Shut down the WASSP Processor and the BTxR and do a complete restart. If the error message continues to be shown, refer to the troubleshooting section on Page 76, or contact your dealer for further assistance.

9.9 Why is there a ring displayed just above the seaoor? What causes these ‘ring’ marks? How can I get rid of them?

This ring is a by-product of the multi-beam technology of your WASSP system. It is supposed to be there but in practice we want to make it as dicult 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 eect 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.

► 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.

► Gain settings

This ring will appear more or less signiﬁcant as the Gain Control dial is changed (see “Gain Control” on page

7). The Normalise option will change the relative intensity.

► Shading of Receiver

Any dierence 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.

► 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.

► 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.

► Electronics Failure

If one or more central channels fail in the electronics this will increase the intensity of the ring.

► 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 (see “Conﬁguration Manager” on page 45).

Operator Manual

Frequently Asked Questions (FAQs)

9.10 What is this constant signal on the sonar/sh nder display?

There are many sources of noise, interference and general acoustic reﬂections which can make these displays dicult to use. A description of the dierent 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. If you wish to continue using your other sounders you can suppress this noise using the Interference Filter option.

► 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 o the ship’s 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 120degree transmission swath. If a strong signal follows the boat and is within the dimensions of the ship then this signal is probably a reﬂection o your own ship. This will make it hard to detect ﬁsh at this depth but otherwise shouldn’t aect 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 BTxR 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 o 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.

9.11 Why is my WASSP System not tracking the Seaoor?

Any source of noise mentioned in the answer to 9.9 and 9.10 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 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 and when the Range Dial reads 100m the system acquires to 210m. If the acquisition depth (i.e. range dial) 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.

► Fish

Occasionally a very large dense school of ﬁsh can be detected as a mountain on the seaﬂoor. This should be easy to determine with a second pass over the area at a later time. This function also allows wrecks to show on the contour display as these are often similar in density to ﬁsh schools.

► GPS Position

If there is no position input, the WASSP system will not output depth data and will cease to map the seaﬂoor.

► Minimisation

The seaﬂoor tracking is aected by the Minimisation level; ensure this is set appropriately as described in the Installation Manual on page 49.

9.12 Why doesn’t the seaoor 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

The standard Furuno SC-50 and SC-30 Heading sensors have a 1.2 second delay on GPS data. Ensure that any GPS delay is entered into the Sensor Tab of the Ship Setup as this will cause large errors in depth (see “Sensor” on page 49).

► 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 eectively determines the dierences 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 the turn aecting 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.

Operator Manual

Frequently Asked Questions (FAQs)

► Water Temperature

The water temperature and salinity aect 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 on page 48. 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 correction is essential for matching up overlapping swaths. If you have disabled the Tide correction (see “Tides Tab” on page 51), the swaths will rarely line up on your WASSP displays. Ensure that the ZDA sentence is being collected and sent to the WASSP Processor so it can determine the UTC time and use the correct tide compensation value.

► Transducer Osets

The transducer, GPS and draft osets 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 Oset

If there is a ﬁxed oset 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.

9.13 Why does the seaoor move if the system is motion compensated?

The acoustic views are only compensated for vessel roll to save on processing time and to avoid creating artefacts in the data. If the Sonar display is rotating with the vessel, 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.

► Check roll information is being received

Open the Sensor Data Tab of the Raw Info window and check that a roll signal is being read by the WASSP system (see “Sensor Data Tab” on page 40 for more information). You should see an orange line on this

display if the roll information is being processed.

► Check that the device that you receive roll information from is on and that all your serial cables

are still connected to your WASSP Processor.

► Check that the correct sensors are selected in the Ship Setup, this conﬁguration could have been

inadvertently changed.

► Check that the Roll Conﬁguration settings have not been changed.

If the transducer has been re-installed, the Swap Array setting could have changed in which case you will need to invert the Swap Roll setting. If the roll oset 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).

► 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 piece of seaﬂoor and remember that a vertical shift is expected if there is vessel roll, pitch and or heave. These artefacts should be mostly removed when you look at the charting displays which is corrected for the measured attitude elements.

9.14 The MODE button animates as if pinging but nothing happens. What is wrong?

The charting displays will not update without enabling the GPS information, seaﬂoor proﬁle information and mapping. Check your GPS is on. This can be validated by checking the Network window or Transfer Task diagnostics displays. If the seaﬂoor line is not being traced on the Sonar display or the Mapping has been disabled, then new data will not be added to the charting database.

Increase the gain, and range. Can you see noise on the Sonar display? If not, reset the power to the BTxR, and reset the WASSP Processor 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 error section of this FAQ (page 60).

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.

9.15 Why is the Key Pulse from my secondary sounder not triggering the WASSP system?

► Ensure you have wired the input correctly, and that the input signal is suitable (see “4.2.2.3 Key

Pulse Connection” on page 19 of the Installation Manual).

► Be mindful that the KP Activity LED on the Network Window is not an accurate representation of

the input signal, and merely indicates KP state changes within WASSP’s data acquisition time in each ping. This activity LED may not light up at all if the Master system pings slower than WASSP, even though WASSP may ping in sync (when in slave mode).

► Currently there is a known issue that keying pulses with pulse widths smaller than ~0.1ms may

not trigger the system correctly. It is recommended that you run the WASSP system as Master, and set the secondary sounder as the Slave.

Troubleshooting

10. Troubleshooting

If the WASSP program provides no data when you transmit, check the following:

► Ensure that all cables and connections have been installed correctly. For example, TCP/IP cables,

GPS, NMEA sensor, BTxR cables and so on (see “2.1 WASSP System Interconnections” on page 5 of the Installation Manual).

► Software installation and settings. See Checking Software Installation procedures below. ► NMEA data sentences. See Step 5 of the Checking Software Installation procedures below.

Conﬁrm that the Device Connection Indicator for

the Dongle and BTxR are both green.

If the Dongle indicator is red, plug in the WASSP Dongle and Rescan (see page 36).

If the BTxR indicator is red, ensure the BTxR is powered ON and connected to the correct network port of the WASSP Processor via the supplied ethernet cable (see “APPENDIX A - Speciﬁc WASSP Processor Information” on page 64 of the Installation Manual).

Conﬁrm the Transfer Task symbol is present in the

Windows Task Bar.

If not in the Task Bar, run the Transfer Task. Click Start > All Programs > WASSP > Transfer Task.

Open the Transfer Task then the NMEA tab.

Check that the COM ports are correctly conﬁgured to receive the incoming NMEA data. If the Activity LEDs are RED, there is a problem. Check that only COM 1-4 are selected for the NMEA ports.

Restart the WASSP program.

If the system is correctly conﬁgured and the BTxR is ON, the MODE button turns YELLOW almost immediately while performing a self calibration, and turns BLUE approximately 3 seconds later.

Switch to the charting view and conﬁrm that the

vessel icon shows the vessel in the correct position.

Doc. P/N: WSP-009-008 Version: V1.3 Issue Date: April 2014

www.wassp.com

Open the Raw Info display from the Utility Panel, then the Sensor Data tab.

Conﬁrm that the Roll, Pitch, Heave and Heading readings are all active and correct.

Click the MODE button to start pinging.

Conﬁrm that the icon animates while pinging, showing a pulse moving down from the vessel.

Switch to the Sonar display.

The Range Control might have locked on to an incorrect depth. Adjust the Range Control dial so that the returned signal from the seaﬂoor can be seen on the Sonar display.

Double-click on the range indicator to switch between automatic range and manual range.

On the Main Menu, set the Power Level to Automatic.

Double-click on the power level indicator to switch between automatic power and manual power.

Cycle through each of the layouts for both the

Acoustic and Charting views, and conﬁrm that they all display and draw correctly.
