P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 www.enl.co.nz Operator Manual Purpose of this Manual This operator manual describes how to operate the WMB-160F Multibeam Sonar System program through its graphical user interface. Introducing the WMB-160F Multi-beam Sonar System The WMB-160F is a multi-beam Sonar system that uses wide-angle sonar transducer to profile the water column and seafloor to very high resolution. It is this unique combination of multi-beam sonar and computer processing power which provides you with unparalleled information about the fishing 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 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 WMB-160F can be applied to a variety of fishing methods, as well as search and rescue, customs, and police applications. Main Features The WMB-160F 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° foreaft while the receive beam covers 10° fore-aft, displaying a highly detailed picture of the marine environment. www.enl.co.nz Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 Operator Manual ► ► ► ► ► ► ► ► ► ► ► ► Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 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-160F, 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. 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-160F can generate and store very detailed seafloor profiles. Digital signal processing (DSP). Using DSP technology, the WMB-160F 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. Operating at a frequency of 160 kHz provides high seafloor definition at depths down to 200m. 2-D and 3-D zoom. 2-D zooming from 250 m out to 3 km. 3-D zooming from 10 m out to 1 km. 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, 100 m depth gives 200 m 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 3-D. 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 transceiver firmware are both upgradeable as new software features are developed. www.enl.co.nz Operator Manual System Configuration Figure 1 – Overview of a Fully Functional WMB-160F Sonar System www.enl.co.nz Doc.

This represents a sonar view of the water column and seafloor as seen from behind the vessel. See Figure 10. TIPS If there is a secondary sonar or sounder operating on the vessel, you may see pulses of interference from this device on the sonar, triple beam, and sidescan displays. To reduce this interference select the interference filter in the Advanced Options box. See Advanced Options for details. A 120° wide by 4° long swath or footprint is covered. The system generates 112 beams over the 120° footprint to provide a very high-resolution sonar view. The centre 90° 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).

Options Click to display further options: • Bottom Lock – this enables 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 this flat bottom image enabling better discrimination between bottom fish and the sea floor. • Triple Beam – when ticked, Triple Beam displays the view below the vessel from the port, middle, and starboard beams. When not ticked, the middle beam only displays the view below the vessel. The port beam is on the left or top (depending on status of the Horizontally check box). The starboard beam is on the right or bottom. • Options Sub-menu Seafloor Line – is the software-generated line of the estimated profile of the seafloor. www.enl.co.nz Doc.

The Port beam is at the top of the screen and the Starboard beam at the bottom of the screen. When not checked, the triple beam windows are drawn vertically, with the Port beam on the left and the Starboard beam on the right of the screen. See Figure 11. • Seafloor Tracking – 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. Seafloor Tracking must be selected in the sub-menu and the Range Control Knob set to automatic (GREEN). If Seafloor Tracking is deselected in the 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). • Triple Beam Angle – represents the angle between the centres of the three beams and can be set to 5, 10, 15, 20, 30, or 40° settings. • TIPS Beam Width – represents the width of the individual beams and can also be set to 5, 10, 15, 20, 30, or 40° settings. Selecting a 10° A broader beam provides better coverage and less chance of missing fish marks, but with less definition. A narrower beam width means higher definition to the information, providing a better idea of the fish density and the shape of the bottom. beam width with a 20° triple beam angle will therefore give a 50° swath for the triple beam view. See Figure 12. Figure 12 shows the differences between beam angle and beam width. Note, these settings are set up in the single / triple beam view, but also affect the beam angle and beam width of the sonar view. They are shown here in the sonar view for descriptive purposes only.

Initially set to zero, a higher number will ignore small echo signals and thus prevent noise showing up as fish targets. Reducing the Fish Threshold number will increase the sensitivity but will result in echo returns due to noise showing up as fish targets. Try varying the Fish Threshold setting up and down until you get one which is optimum for your vessel’s installation. Backscatter Overlay Options Selecting Show Backscatter in the right-click options applies backscatter to the contour view of the seafloor along the profiled area. The colour scale is BLACK to WHITE (unless colour backscatter is ticked) with: • BLACK = NO return (weak echoes). • WHITE = HIGH return (strong echoes). The lighter the colour on the screen, the stronger the return. Using this display you can determine areas of hard / rocky ground (light areas) and areas of soft, sandy, or kelp covered ground (dark areas). Right-clicking in the sidescan view opens the right-click options box. Click Gain to open the Backscatter Gain box, allowing you to adjust the gain factor (BLACK and WHITE) for both the sidescan and contour backscatter views. Figure 16 shows Gain being selected in the right-click options box See Sidescan View for more details on interpreting backscatter information. Sidescan gain adjustment. Note: Recommended Gain Threshold Settings for the 160kHz WASSP system is between 60 and 65. This is set at time of installation and should NOT be changed. Sidescan gain threshold limit Figure 18 –Sidescan Options Box Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 www.enl.co.nz 34 Operator Manual The gain controls for both backscatter and sidescan modes are in the same options box (see figure 16). This box is automatically shown whenever the backscatter mode is selected from the contour map view. The options box can also be selected by right-clicking in the sidescan view screen. Colour Backscatter If the “Colour Backscatter box is checked, the backscatter information will be displayed in colour. Varying the backscatter gain will now change the colour of the backscatter display from blue (minimum backscatter) to red (maximum). Colour backscatter helps display seafloor changes even more clearly than the black and white display mode. Setting the Gain Threshold Limit: The Gain Threshold Limit sets a reference value for the maximum level of backscatter that will be scaled into white colours. The limit is typically between 60 and 65, and is set at time of commissioning the system. Once set the limit rarely needs adjustment. To set the limit, sail over an area of seafloor that is known to have a high backscatter return (for example rocks). Adjust the Backscatter Gain Threshold value up or down until the map is very dark except for small white areas where the highest backscatter is received. The Backscatter Brightness can then be adjusted to give the desired picture. The brightness control can be varied at any time without affecting the saved backscatter maps, but changes to the Threshold Limit will alter the reference point for all backscatter values saved after the change. N.B. - The Gain Threshold Limit can only be changed by a technician. Requires a Technician Dongle. Warning - changing these at a later date will cause earlier recorded seafloor backscatter data to be displayed incorrectly. Advantages Shows the vessel location and heading relative to the seafloor features, fish marks, and backscatter information. When showing fish overlay, colours for depth (seafloor) revert to greyscale. Mark option. History is saved and the data can be seen when visiting an area days or years after collection. Backscatter overlay shows changes in seafloor type clearly. Good for navigating a trawl path for fish only found in specific areas. Disadvantages In shallow depths <45 metres, resolution of the contour view is less than the sonar view. The contour view picture relies on software algorithms to trace the seafloor correctly. Wrecks may trace as fish and vice versa. www.enl.co.nz Doc.

The WMB-160F sonar calculates seafloor profiles every pulse. These profiles are automatically stored on the computer. As the vessel covers an area, a detailed seafloor profile is generated. This profile can be viewed in either the 3-D or contour screen. Figure 17 is an example of a 3-D view showing a three-dimensional image of a seafloor area that has been profiled using the WMB-160F.

Colours Clicking the Colours button opens a Colours dialog box that allows you to alter the colour settings for depth. Changing the depth colour settings in this box also changes them in the Contour view mode. View Clicking the View button opens a dialog box with the following view options available: ► North Up – means the 3-D view is always shown in a North-up mode, like the contour view, as per normal plotter functions. ► Free Rotate – means the 3-D view can be rotated freely by the mouse to view and highlight any particular area of interest. ► Course Up – means the 3-D view is always shown from just behind the vessel rotating as it turns. ► Behind Vessel – As with Course Up but the view is 100 to 300 metres behind the vessel. Height Clicking the Height button opens a Height dialog box that allows you to alter the height of the 3-D image. The options are 1:1, 2:1 and 3:1. Changing the height ratio from the default value of 1:1 causes a vertical exaggeration of the height of the 3-D image. This allows sea bed objects to be accentuated, and may assist in determining of the nature of the sea bed or objects lying on the seafloor. Note: WASSP systems with earlier versions of software had the height set to a fixed ratio of 2:1. Doc.

Changing View Angle The angle that the 3-D image can be viewed at can be changed. Click anywhere in the 3-D view screen and then hold down the left mouse button. The 3-D view can then be angled around the vessel position to optimise the view by moving the mouse. Rotation of the view is performed in the same way, but requires Free Rotate to be selected in the right-click View options Advantages Shows seafloor features in 3-D allowing an operator to gain a more complete picture of the seafloor. Rotation allows an operator to better distinguish patterns, trends, and objects.. Disadvantages Smaller viewing area than the contour view. No fish or hardness indications. In shallow depths <40 metres, resolution of the contour view is less than the sonar view. The contour view picture relies on software algorithms to trace the seafloor correctly. Wrecks may trace as fish and vice versa. 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 18. 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 www.enl.co.nz Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 Operator Manual 39 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 contour or 3-D views. In Figure 18, 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.

For example, if you are in New Zealand waters during the period that includes daylight saving, the Local Time Difference setting should be set to 13, 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 13 hours (as shown in Figure 21), then the local time would actually be 11.00 pm.

P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 Operator Manual 53 Interference Filter 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 (ON) if you have another sounder or sonar on your vessel that operates at the same time as the WMB-160F. Best results are achieved if all other sounders are turned off. Set the Interference Filter Level to High when encountering strong interference, and Low when interference is weak. Smoothing Smoothing only affects the single beam view. It allows averaging of the individual seafloor samples in the longitudinal (fore-aft) direction to eliminate the quantised or pixelated effect that would otherwise be visible on the single beam view. Generally, the best value for smoothing is 2. TIPS Refer to the Installation Manual for more information on the Ignore Dregrees to and Minimisation settings as well as a description of the I/Q Bar Graph and Raw Data information displays. Figure 26 –Advanced Options Box Minimisation 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 the Installation Manual IM_WMB160F_SYS, for more information on selecting correct minimisation settings for your installation. Clutter Clutter describes the filtering process used to remove low level (noise) signals. The control sets the threshold for the minimum signal level that will be displayed. Doc.

Provided the system has been installed correctly and all commissioning procedures performed successfully, these buttons provide access to the settings that may need to be changed to improve the operation of the WMB-160F system. N.B. - Some configuration panels are able to be viewed but not changed. If you can’t change them, a Technician Dongle is required. Technician Dongle With a technician’s dongle connected to a USB port on the computer, all four buttons are available for further setup and diagnostics of the WMB160F system. The settings provided by the Options and BTXR Options buttons do not help the system operator to use the system. Changes made to the settings under these buttons are more likely to hinder operation. They are mainly available to allow advanced diagnosis of the system and any problems it may have. These functions can adversely affect the performance of the WMB-160F system. Read this section carefully as any changes you make may not be recoverable. Ship Setup Button In the Technician Utility box, click Ship Setup to open the Ship Setup Options box. See Figure 27. Six page tabs provide access to the following ship setup settings: ► ► ► ► ► ► ► General. Offset Corrections. Sound Speed. Sensor Values. System Setup. Power. Navigation Most of the Ship Setup Options should only need to be configured once in the lifetime of the WMB-160F installation. These are normally set during installation and commissioning of the system. The Ship Setup options that may need to change during operation are: ► ► ► Device Settings (under General) – if changes are made to the vessel’s sensors. Sound Speed. Power – set power levels to suit changes in seafloor depth. See Installation Manual for commissioning tests using Ship Setup options. Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 www.enl.co.nz 58 Operator Manual General Tab General settings provide: ► ► ► ► Transducer Depth. Provides the ability to compensate for the depth the transducer is mounted below the water line. Pitch / Roll Sensor Offsets. If using an external sensor connected to the transceiver, these settings allow you to enter the specific zero angle voltage and sensitivity voltage characteristics of the roll sensor you are using. If a motion sensor is not installed, it is recommended that you disable roll compensation. Heading Offset. Provides a heading offset dial so that compensation for errors in the ships heading can be corrected. The most common reason for a heading offset is when magnetic heading information is being given instead of true heading. If true heading is being given, the heading offset is usually 0. Otherwise a heading offset should be entered as appropriate. Heading offset can also be used to compensate for transducer misalignment, causing a heading error. If the vessel is travelling in a straight line in the direction it is facing, you can adjust the heading offset quite accurately by eye. Look at the vessel track on the contour display and the bearing line and adjust the heading offset until they are parallel (the bearing line should point away from the track made on the contour display behind the vessel). If the vessel’s heading changes erratically, make sure that there are not multiple conflicting heading sentences being fed into the WMB-160F’s serial ports. Vessel Information. Vessel’s name, country and home port may optionally be entered here. Note, roll sensor settings shown are the default values. Figure 29 –Ship Setup Options Box – Showing General Tab www.enl.co.nz Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 Operator Manual 59 ► Device Settings. Provides a Positioning Sensor and Motion Sensor drop down list to select the appropriate installed sensor for both device settings. The advantages being 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.. ► The BTxR Serial Number and Transducer Serial Number are filled in at time of installation. Offset Corrections Tab The Transducer Heave Compensation check box should be selected if the x, y, and z offsets have been recorded. This enables the system to compensate for heave generated by the vessel pitching and rolling. See Figure 28. Note, offset values shown are examples only. The actual values for your vessel must be used Figure 30 –Ship Setup Options Box – Offset Corrections Tab Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 www.enl.co.nz 60 Operator Manual Sound Speed Tab 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. See Figure 29. It is recommended that sound speed sensors are used for obtaining an accurate sound speed value. A general rule of thumb for sound speed setting over a flat seafloor would be: Seafloor Profile: Convex or flat INCREASE sound speed value Seafloor Profile Seafloor Profile: Concave DECREASE sound speed value Seafloor Profile TIPS Sound Speed Guide: • 1500 m/s for sea water. • 1435 m/s for fresh water. Salinity values: • 35 for sea water. • 1 for fresh water NMEA Temperature: • If the Surface Temperature data window does not display a valid temperature value, check that the incoming NMEA data contains the “MTW” sentence. Figure 31 – Ship Setup Options Box – Sound Speed Tab NMEA Temperature If the Use NMEA Temperature check box is ticked, the WASSP application software will use NMEA temperature data from an external temperature sensor and is displayed in the “Surface Temperature” window. The “Temperature offset” box may be used to input an offset to correct for any error in the external temperature sensor. www.enl.co.nz Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 Operator Manual 61 Salinity The default value for the salinity of sea water is 35. This value should not be changed unless the actual salinity of the surrounding water is known. If fishing in fresh water, the value should be set to 1. Clicking on the Calculate button will re-calculate the Surface Sound Speed value based on the Salinity and Surface Temperature values. 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 used when calculating and displaying backscatter information. For an 160kHz WASSP system, a default value of 25dB/Km is used. This is set at time of installation and affects the appearance of the backscatter display. This value should not be changed. See Installation Manual, Commissioning Procedures, Sea Trials for more information. Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 www.enl.co.nz 62 Operator Manual Sensor Values Tab The Sensor Values tab provides a roll corrections slider to compensate for any offset between the WMB-160F transducer mounting and the water line. If the transducer and motion sensor are not mounted on the same angle this will also require compensation. A Pitch Offset box allows you to set a pitch offset setting in degrees. Figure 32 – Ship Setup Options Box – Sensor Values Tab Inaccuracies with roll correction make it harder for the system to compensate for any changes in roll. If roll correction is enabled (on the Sensor Values tab) and the vessel is rolling less than 25°, the sonar picture should remain in almost the same place from ping to ping. If the sonar picture moves with the vessel then the roll compensation setting is likely to be wrong. The Swap Roll selection check box allows toggling to reverse the polarity of the roll sensor. If correct, the display does not move. If not correct, the display could roll 2x what the vessel is actually rolling. If the roll sensor and or the transducer are not mounted entirely flush you may have to move the Roll Correction slider to compensate. The calculation of the Roll Correction value is now an automatic function of the software and is set at time of installation when the Sea Trial Commissioning Patch Test (Roll Correction) is performed. Provided the “ Use Patch Roll” box is checked, the WASSP application will use the calculated value. www.enl.co.nz Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 Operator Manual Do not engage the Extra Roll Filter in calm conditions. 63 The Swap Array check box is used to account for wiring differences between different versions of the WMB-160F. If you find that the shallow part of the harbour, or a significant landmark, is appearing on the wrong side of the Contour / 3-D display, then there is a chance you have this option selected when it should not be, or vice versa. Engage the Extra Roll Filter when the vessel is rolling greater than 5º and the roll compensation is not fully compensating for the roll motion. Pitch Offset A Pitch Offset box allows you to set a pitch offset setting in degrees to correct for transducer and motion sensor mis-alignment. See Figure 30. GPS Time Delay All GPS positioning systems have some delay from receipt of the satellite signal to outputting the correction data. When a Furuno SC-30 is used as the source of position data, this delay is 1.2 seconds. and equates to an error of about 10m in the location of an object on the seafloor. This value should only be changed if the type of position sensor is changed. Motion Delay The motion delay value is displayed for information only and cannot be changed. The value is determined by selecting the type of motion sensor in the Ship Setup Options General Tab - See Figure 29. For more detail on how to set the values on the Sensor Values tab, refer to the WASSP Installation Manual, Commissioning Procedures, Sea Trials. Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 www.enl.co.nz 64 Operator Manual System Setup Tab The System Setup tab allows you to configure the following system wide settings: ► ► ► ► ► ► Contour Path. Indicates the directory where the contour map profiles are stored (History of seafloor profile in areas the vessel has been mapping). Snapshot Path. This is the location where Snapshot data is stored. Depth Units. Allows you to select the unit of measurement for depth throughout the system in metres, feet, or fathoms. Changes take effect immediately. Screen Resolution. Allows you to select the screen resolution (1024 x 768 minimum recommended) and screen appearance (Windowed, No Title Bar, Full Screen). The Apply button must be clicked and the WMB160F program restarted before the changes take effect. OpenGL Buffer. Normally set to “Double” but some computer graphics chips (e.g. Intel), require “Single”. Change to “Single” if Polar/3-D displays are not drawing correctly when the WASSP application is running. Smoothing Options. The setting chosen for smoothing depends on how much bottom detail is required. For flat bottom and good meshing of bottom swath, choose high. Where bottom detail is important, e.g. rocks or wreck outline, choose a lower setting. Lower settings may result in a more uneven appearance of the ocean floor between adjacent mapping swaths. The chosen setting is a compromise between bottom detail and uniformity of the ocean bottom map. The Default value sets smoothing to Medium. Select Screen Resolution Windowed: Standard Windows layout with Title Bar and Task Bar. No Title Bar: Standard Windows layout but with no Title Bar or Task Bar. Full Screen: No Title Bar and Task Bar at full screen resolution (normally 1024 x 768).

A Defaults button sets all fourteen power levels to a default setting. When setting power level depth settings individually, click the Apply button when you have completed the settings. 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. See Figure 32. The “Use Power Correction” check box is normally ticked. This corrects for changes in power levels in SideScan and Backscatter modes. Click OK 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. Figure 34 –Systems Setup Box – Power Tab Doc.

Note the Trouble Shooting section of this manual covers most of the typical operational problems, and this section should be consulted olny after reading the Trouble Shooting section. Each FAQ question is numbered and answered in the following pages. Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 1) The WMB-160F system is transmitting too slowly, how can I speed it up? 2) Why does the range not change on the display when I move the Range Dial? 3) Why is no seafloor profile generated in the 3-D or contour views after the system initially starts transmitting? 4) Why do gaps appear between the swath footprints in the contour and 3-D views? 5) The WMB-160F system has stopped transmitting without operator intervention. Why? 6) When I click the MODE button, or run a replay (demo) file I get no picture on the display. Why? 7) When I press the STBY button the button goes red and a number on it counts up, but there is no activity on the WASSP display. How do I fix this? 8) What does the error message that appears when I run WASSP mean? Is my WASSP system faulty? 9) Why is there a ring displayed just above the seafloor? What causes there “ring” marks? How can I get rid of them? 10) What is the constant signal on the sonar/fish fuinder display? 11) Why is my WASSP system not tracking the seafloor? 12) Why doesn’t the seafloor line up when I go over it again? 13) Why does the seaflloor move if my WASSP system is motion compensated? 14) The mode button animates as if pinging but nothing happens. What is wrong? www.enl.co.nz 80 Operator Manual Question 1 The WMB-160F System is transmitting too slowly, how can I speed it up? Remember that the WMB-160F 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 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 WMB-160F program consume processing power and take processing time away from the WMB-160F system, slowing down the rate of transmission. For optimal performance, ensure the WMB-160F program is the only application running. Question 2 Why does the range not change on the display when I move the Range Dial? Double-click each viewing mode (sonar, single / triple beam, 3-D, contour, and sidescan) 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. Question 3 Why is no sea floor profile generated on the 3-D or contour views 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 the Contour Map button is ON. See Page 11. www.enl.co.nz Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 Operator Manual 81 Question 4 Why do gaps appear between the swath footprints on the contour and 3-D views? 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 computer is giving processing power to another operation (other than the WMB-160F program) causing processing of sounding information to take longer as a result lowering the transmission rate of the WMB-160F system. The GPS data has come in at irregular intervals. The WMB-160F system has stopped. See Question 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. Question 5 The WMB-160F system has stopped transmitting without operator intervention? If time is taken from the system by another application for long enough, the WMB-160F 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 tool bar. If this does not work, try to restart the WMB-160F program and the transceiver. The most likely cause of this is a sudden power supply spike or drop. Doc.

How do I fix this? First make the following checks of your WASSP installation: • Check that the Transceiver power is ON and the green LED light on the front panel flashes every few seconds. • Make sure the CAT5 network cable is connected at both the Transceiver and the PC 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 PC screen) and was running when you started WASSP. If not, restart WASSP after running the Transfer Task application. Transfer Task icon Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 www.enl.co.nz 84 Operator Manual Question 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 computer from becoming full. A computer with a full disk drive becomes unusable. Try to have at least 10 Gb of free drive space at all times to allow sufficient room for system file management. • 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 computer 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. • 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. www.enl.co.nz Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 Operator Manual 85 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. • LINK ERROR: This error message indicates that there has been a data corruption internally in the Transceiver between the Receiver and the DSP. The WASSP system will not function at this point. Reset the power to the Transceiver – if the message continues to be shown return the system to your dealer for service. • 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 Transceiver Transmitter unit has failed - Contact your Dealer for further assistance. • CARRIER REF ERROR: This error message indicates that there has been a failure in the synchronised internal timing chain of the Transceiver. If restarting the power to the Transceiver does not clear this error return the Transceiver to your dealer for service. • SERIAL FAILURE: This error message indicates that an internal DSP board communications failure has occurred. The WASSP system will not function correctly at this point. Turn the power off/on at the Transceiver – if the message continues to be shown return the system to your dealer for service. • System Initialisation Failure: This error implies that the system was not fully operational when the WASSP GUI was run. Shut down the shuttle P.C. and the Transceiver and do a complete re-start. If the error message continues to be shown, refer to the troubleshooting section on Page 41, or contact your your dealer for further assistance. Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 www.enl.co.nz 86 Operator Manual Question 9 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 multi-beam 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 sea floor tracking algorithms or being confused as fish marks the Minimisation feature allows these rings to be suppressed on the Sonar display. The ring is caused by mathematical limits – when a very strong signal arrives at the receiver it creates a shadow like effect that creates a ring of much weaker echoes. Unfortunately the signal return from the sea floor is many orders of magnitude stronger than a fish echo and thus the shadow of weaker echoes are comparable to fish targets. How do I know if I have a problem then? – From experience in the field a minimisation level around 3000 is normal. Some systems may have as low as 1500 others up to 5000, often as a result of newer or older technology. If the minimisation required to remove traces of these rings is much higher then there could be a problem. If you have a minimisation level of lower than 6000 and can’t see any rings then your WASSP system is probably operating correctly. 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. There are a number of ways to optimise the performance of your WASSP system and to reduce these rings: a) Too much power – This is the most common cause of problems. When there is too much acoustic energy in signals returned from the sea floor they may distort. Distortion of the signals will cause ambiguity in resolving the position and thus create rings of very high amplitude. b) 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. www.enl.co.nz Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 Operator Manual 87 c) Reconnection Fault – If the cable from the Transceiver 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 are in the correct order. d) 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 recalibrate. e) Electronics Failure – If one or more channels fail in the electronics this will increase the intensity of the ring. f) Configuration – Changes made in the Technician configuration could significantly change the system performance. Check Windowing, Power and Pre-processing options. If possible reverse any changes made if the system configuration deteriorates. If the changes are unknown make a note of all ship setup information, backup the WASSPPRO.INI file and then delete the original to run the WASSP system with default configuration settings. Question 10 What is this constant signal on the sonar/fish finder display? There are many sources of noise, interference and general acoustic reflections which can make these bathymetric 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. 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 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 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 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. Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 www.enl.co.nz 88 Operator Manual 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. Question 11 Why is my WASSP System not tracking the Seafloor? Any source of Noise mentioned in the answer to Question 9 above can cause the seafloor detectection 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 reacquire 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. Conversley, too low a power level may result in the signal levels from the sea floor 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 sea floor profile swath 3.7 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 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 reacquire the seafloor. www.enl.co.nz Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 Operator Manual 89 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 the WASSP system will not output depth data and will cease to write contour maps. Minimisation – The seafloor tracking is affected by the Minimisation level; ensure this is set appropriately as described in the Installation Manual on Page 50. Question 12 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 – 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 Ship Setup Configuration as this will cause large errors in depth. 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 sea floor 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 sea floor 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. Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 www.enl.co.nz 90 Operator Manual 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. Question 13 Why does the Seafloor Move if the system is Motion Compensated? The Contour and 3D display are fully motion compensated. The other displays 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 Check Roll Information is being received (Open the Raw Information Form and check the Roll Graph displays roll waveforms). You should see a red line on this display if the Roll information is being processed. Roll Data Information Pitch Data Information • 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 Ship Setup Form, this configuration could have been inadvertently changed. www.enl.co.nz Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 Operator Manual 91 • Check that the Roll Configuration settings have not been changed. If the transducer array has been re-installed, the Swap Array setting could have changed in which case you will need to invert the Roll Configuration. When in doubt, use the values that were recorded in the Installation Manual at time of commissioning. If the roll offset is incorrect a slight roll of the display will occur. If the roll polarity is incorrect you will see a doubling of the actual vessel roll (i.e. complared with having the roll compensation disabled). • Use the WASSP Network Status screen to check that you have not disabled the Serial port. Check that the serial port with the attitude data is being used. These must be on for data to be used by WASSP Check Sum on is recommended. Finally if the sea floor is not uniformly flat you could see rapid changes in the sonar display with each ping as the ship moves across the sea floor. As there is no heave or pitch compensation on this display it will often move up and down and if the sea floor 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 WASSP Contour display which is corrected for the measured attitude elements. Doc. P/N: OM_WMB160F_SYS Version: V1.6 Issue Date: 30 Nov 2009 www.enl.co.nz 92 Operator Manual Question 14 The mode button animates as if pinging but nothing happens. What is wrong? If you are looking at the Contour or 3D displays these will not update without GPS information, sea floor profile information and mapping is enabled. Check your GPS is on. This can be validated by checking the network input screen or transfer task diagnostic 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 Contour Maps. 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 that section of the FAQ. Ensure that the Transducer has not been disconnected from the Transceiver, 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. www.enl.co.nz Doc.
