ODOM Sonar UI - User Manual Introduction 3

1 Introduction

1.1 Odom Sonar UI This manual is the user manual for the Odom Sonar User Interface (SUI).

The chapter ‘Odom Sonar System’ describes the general setup of an Odom system to the SUI (see page 5).

The chapter ‘General Information’ describes; how the panes work and what options are available in the toolbar (see page 7).

The chapter ‘Operation’ describes the Operation mode of the Sonar UI. The different panes that can be used in conjunction with the screens will be explained in detail (see page 23).

The chapter ‘Service’ describes how to check the status of the complete sonar system by viewing the system diagram and BITE information (see page 57).

The appendix ‘MB2 Turn-On Procedure with Integrated HPR’, describes the turn-on procedure of the MB2 in case an integrated HPR is installed in a MB2. (See page 65.)

This manual is also available as a help file in the Sonar UI. Use F1 or in the toolbar of the Sonar UI to open the help file.

2.1 Introduction This section describes briefly the Odom sonar system as connected to the Sonar UI (SUI).

2.2 Odom Sonar System Overview The next figure illustrates a common setup of an Odom sonar system.

Figure 2-1 Overview Odom sonar system

The sensors are interfaced to the Odom Real Time Appliance (RTA) box. The RTA generates the aligned and time tagged sensor data streams to the MB Controller computer. The MBCenter, the Sonar UI (SUI), and a 7K data logger run on this computer. An additional computer with the Survey

package (e.g. Teledyne PDS) is connected to the MB Controller computer.

Not running the acquisition software and the SUI on separate computers may degrade the system performance.

Sensor data is retrieved by RRIO; the RRIO is set up in different panes and distributed by the MBCenter.

The sonar head and the RTA have fixed IP address numbers. For the sonar head this is 192.168.1.100 and for the RTA this is 192.168.1.101. This means the MB Controller computer and a connected acquisition computer should have an IP address within this range.

2.3 Starting After installation of the Sonar UI a shortcut will be available on the desktop.

Figure 2-2 Desktop Sonar UI shortcut

Double-click the shortcut to start the Sonar UI.

When the MBCenter is installed, the Sonar UI will automatically connect to the MBCenter.

A warning pops up when already an MB2Center runs.

ODOM Sonar UI - User Manual General Information 7

3 General Information

3.1 Introduction To setup and operate the sonar from the SUI, use:

Panes. (see the next section).

The Sonar UI Toolbar. See page 13.

The Screen Toolbar and Context Menu. (See page 21)

This chapter describes how the panes, the toolbar options and the screen toolbar work.

3.2 Arranging the SUI Panes

3.2.1 General

The SUI uses: settings panes, control panes and a messages pane.

A pane opens by clicking on the corresponding tab on the right side or bottom of the screen.

The settings panes on the right side are:

Display

The LED indicator will show the status of the roll stabilization. Be aware the status of the LED relates to the last received ping. This means that when the sonar does not ping the status of the LED is not updated.

The different colors are:

Blue: When the SUI is started, the roll stabilization is not yet initialized.

Grey: The roll stabilization is initialized but disabled in the Hardware pane.

Green: The roll stabilization is enabled and working.

Yellow/Orange – Warning level: The roll stabilization receives a roll value that exceeds ±15°.

Red – Error level: Possible errors are: no attitude data received, roll value exceeds ±35°, or change rate > 10° per second.


Roll stabilization is an important feature related directly to system efficiency which allows the swath width on the seafloor to be maximized, thus increasing line spacing and reducing vessel time.

Under zero roll conditions, the swath is vertical and the center of the swath is directly below the vessel.

Figure 3-15 Swath under zero roll conditions

When the vessel rolls the swath is rotated and the projected swath on the seafloor is laterally displaced.

Figure 3-16 Laterally displaced swaths under roll conditions

This has the effect of reducing the usable swath width due to the distortions on the edge.

Figure 3-17 Reduced usable swath width

With the input from a motion sensor to steer each receive beam dynamically for every sample, the swath stays vertical irrespective of vessel motion thereby maximizing swath.


Figure 3-18 Swath under roll stabilization

3.3.12 1PPS

The LED indicator will indicate if the 1PPS is received or not. Be aware the status of the LED is an indication related to the last received ping. This means when the sonar does not ping the status of the LED is not updated.

The different colors are:

Blue – When the Sonar UI is started the 1PPS is not yet initialized.

Green – The 1PPS is working.

Yellow/Orange – Warning level – No 1PPS received for a couple of seconds.

Red – Error level – No 1PPS received anymore.

3.3.13 Power Mode Warning

The power mode warning is enabled or disabled in the application settings dialog box. On the left side of the toolbar an alarm symbol pops-up when a warning condition take place. The symbol disappears when the warning condition is resolved.

Figure 3-19 Power mode warning

There are two warning conditions:

CPU throttled

Computer runs on battery


3.4 Screen Toolbar and Context Menu When the cursor is moved to the top left side of each individual screen a toolbar will automatically pop up. The toolbar automatically hides when the cursor is moved away.

Figure 3-20 Toolbar automatically pops up when cursorr at top of screen.

The screen toolbar options are also available in a context menu. Right-click the screen to open the context menu. The toolbar and context menu are used to adjust the screen properties. For more details, see the chapter Operation on page 23 .

ODOM Sonar UI - User Manual Operation 23

4 Operation

4.1 General When the Sonar UI is started, it will open in the Operation mode with three screens or the number of screens that were open when the Sonar UI was last closed.

The different screens are:

Wedge (see page 51)

Water Column (see page 53)

Detect (see page 54)

Snippets (see page 55)

Figure 4-1 Sonar UI with three screens

The Main and Advanced panes (at the bottom of the Sonar UI) provide sonar control functions. The various settings panes (at the right side of the SUI) provide options for presenting the sonar data.

The different panes are:

24 Operation ODOM Sonar UI - User Manual

Main (see below) With the Main pane the operator controls the sonar and selects what screens to view during operation.

Messages (see page 33) The Messages pane displays the error messages as they are received in the Sonar UI.

Advanced (see page 28) In the Advanced pane the operator can set advanced sonar settings.

Detection (see page 33) In the Detection pane operator sets the Absolute and Adaptive gate settings for the bottom detection process.

Display (see page 37) In the Display pane the operator can customize the visual properties of the screens of the Operation.

Recording (see page 39) In the Recording pane the operator selects what data is recorded and the recording information is displayed.

Hardware (see page 43) In the Hardware pane the operator sets up the roll and/or pitch stabilization and a dual head system (if applicable).

How the panes are opened and how the panes are moved in the application is explained in chapter Arranging the Panes on page 7.

In this chapter the different panes and the three screens are described.

4.2 Main Pane The Main pane is for general control of the sonar. The choice of screens (Wedge, Water Column/Detect, and Snippets) allows the operator to customize the display layout in Operation mode.

Figure 4-2 Main Pane with Gate and Tile settings

4.2.1 Range

The range setting allows the operator to select how far the sonar will ‘see’.

Figure 4-3 Range

Select the appropriate range scale to keep the image of the bottom detection at or above the widest part of the sonar wedge.


In the next figure have the left wedge a proper range setting and the right wedge an incorrect range setting.

Figure 4-3 Range setting

4.2.2 Power

Power is set for range, if shallow (<10m) set to 1, and move up accordingly as depth increases. The MB2 gain is fixed (not possible to change).

The power setting allows the operator to increase or decrease the amount of power (acoustic energy) that is transmitted into the water.

Figure 4-4 Power

If the power is set to OFF, the system will not ping, but it will continue to receive data provided that the (ping) rate is not set to 0. The sonar system will act as a passive sonar by only receiving data. This is a feature that is very useful for monitoring the ambient noise and interference from the vessel itself.

4.2.3 Pulse Length

The pulse length setting allows the operator to change the pulse length of the transmitted signal.

Figure 4-5 Pulse Length

For a given power setting, a narrower pulse length will provide a higher resolution at a shorter range. A wider pulse length will provide better range but a lower resolution image.

In certain conditions, for example in turbid waters, the narrower pulse length may not operate well. In such circumstances, the wider pulse length may give better short-range performance. This may also be achieved by changing from higher to lower frequency operation.


4.2.4 Gate

The operator is able to enable/disable the required gate mode(s). By default they are disabled. When enabled, the Gate mode button is highlighted.

Figure 4-6 Gate modes with Depth gate selected (highlighted)

Settings for the three gate modes are set in the Detection pane. (See page

33.)

4.2.5 (Ping) Max Rate

The max (ping) rate setting allows the operator to set the number of pings per seconds. The actual number of pings depends on the current range setting.

Figure 4-7 (Ping) Max Rate

The recommended value is the maximum rate to ensure that the highest possible ping rate, depending on the range setting, can always be achieved.

In some instances it may be beneficial to force a lower ping rate than the normal rate associated with a particular range. Examples of this would be instances when the vessel is moving at a very slow rate, and the operator wants to reduce the quantity of data that is generated; or when the sonar is operating in a high-reverb environment where echoes of the previous ping are contaminating the current ping.

4.2.6 Tile

In the Tile frame the different screens can be switched on/off. By default all three the screens are on. When a screen is on the button is highlighted.

Figure 4-8 Wedge, Water Column and Snippets screen switched on

The Wedge and Water Column/Detect screens are always on the left side of the SUI and the Snippets and Sidescan screens always on the right side. If only one of the two screens on one side is open, that screen will use the complete left or right side of the view.


The Water Column/Detect button has three functions: switching on the Water Column screen, switching on the Detect screen, and switching off both.

When a screen is disabled, no historical data will be logged. This means that a screen will start empty if it’s enabled during operation (see also Screens on page 47)

The screens can be resized by dragging the horizontal or vertical divider up/down or left/right. To drag the divider move the cursor over the divider and the cursor becomes a double – horizontal or vertical – arrow.

It is possible to move the horizontal divider up/down separately for the left and the right sides of the Sonar UI. Double-click on the horizontal divider for the left or right side and the other half of the horizontal divider will jump to the same level.

The crossing of the horizontal and vertical dividers can be moved by dragging the crossing dividers. To drag the dividers move the cursor over the crossing and the cursor becomes a cross arrow.

Figure 4-9 Double arrow and cross to resize screens


4.3 Advanced Pane The Advanced pane is for the advanced settings of sonar transmit and receive functions.

Figure 4-10 Advanced Controls

4.3.1 Beam Mode

Beam modes available depend on the license purchased.

It is possible to switch the Beam mode on the fly. For the beam mode the following modes are selectable:

4.3.1.1 Equi-Angle

In Equi-Angle mode the spacing between the beams is equiangular. The beam center-center angular spacing is constant across the swath.

In areas of significant relief and in particular when surveying features such as wrecks and vertical structures such as harbor walls, Equi-Angle should be used in preference to Equi-Distant (see also 4.3.1.2 below).

The number of beams can be set by the operator with the slider. This allows the operator to be able to capture the highest detail using the highest beam density needed. In very shallow water fewer beams can be used to reduce data volumes.

Figure 4-11 Equi-Angle beam mode

4.3.1.2 Equi-distant

Equi-distant mode gives equally spaced soundings across the entire swath using the maximum number of beams.

The spacing between the beams is equidistant. With Equi-distant the spacing is modified to maintain an equal horizontal distance between soundings on the seafloor assuming a flat bottom.

It is recommended that Equi-distant be used for general survey applications where the requirement to achieve a specific number of sounding per cell in the across-track is critical, or where the seafloor is generally flat.

In extreme conditions, using Equi-distant over complex structures can cause magnified artifacts due to the large overlap between beams towards the edge of the sector.


The number of beams can be set by the operator with the slider.

Figure 4-12 Equi-Distant

4.3.2 (Horizontal) Steering

Figure 4-13 Steering

To achieve a correct beam steering in equidistance mode the sonar needs an up-to-date online sound velocity measurement.

The (horizontal) steering setting allows the operator to steer the swath electronically.

The achievable steering depends on the selected coverage angle. See section 4.3.3 below.

The Default button resets the steering to 0. (The coverage angle will also reset.)

The extent of the steering is determined by the maximum swath width. The maximum swath width is 140deg. The outer beam cannot be steered past the maximum swath width. When the swath is steered this way, the individual beam widths increase with the steering angle. A beam steered at 60° is twice the width of a beam steered at 0°.

Figure 4-14 With a swath of 120° the maximum steering is ±10°

60°

70°

10°


Figure 4-15 With a swath of 60° the maximum steering is ±40°

4.3.3 Coverage Angle

The (coverage) angle allows the operator to change the swath width.

Figure 4-16 Coverage Angle

The Default button resets the coverage angle to the maximum angle depending on the selected beam mode. (The horizontal steering will also be reset.)

4.3.4 Center Frequency

Figure 4-17 Frequency

With the slider the operator is allowed to change the center frequency of the transmit pulse. A lower frequency provides a long-range functionality and a higher frequency a high-resolution functionality with a shorter range.

4.3.5 Stacking

Stacking is a way of filtering by which a defined number of images (1-9) are placed over each other and an “average” image is determined from these images. This way a peak value can be removed when the peak does not occur in the other images. The result is a clearer image.

Figure 4-18 Stacking

30°

70°

40°


4.3.6 Absorption

The absorption slider allows the operator to set the amount of loss that is expected through the ambient water medium. The absorption loss is proportional with the salinity of the water and the sound frequency: the higher the salinity or frequency, the greater the loss. Also an increased temperature will increase the absorption loss.

If the exact absorption loss value is not known, a value of 110dB/km for salt water and 70dB/km for fresh water is recommended for a 400kHz operation, and a value of 50dB/km for salt water and 20dB/km for fresh water is recommended for a 200kHz operation.

This value is used in conjunction with the spreading loss coefficient (see 4.3.7 below) to compute the TVG (time varied gain) curve that is applied to the returned signal.

Figure 4-19 Absorption

4.3.7 Spreading

The spreading allows the operator to enter the amount of cylindrical and spherical spreading loss that is expected through the ambient water medium. Spreading of sound through water may be the greatest contributor to the loss of sound. As sound moves away from its source in all directions, the acoustic pressures will decrease with the range.

This value is used in conjunction with the absorption loss value (see above) to compute the TVG (time varied gain) curve that is applied to the returned signal.

In practical situations the transmission loss will lie between 20 and 40dB; in other words, the spreading loss will neither be perfectly spherical nor perfectly cylindrical. Finally, if the sonar operates very close to the seabed or very close to objects in general, near-field effects may yield a transmission loss less than 20dB.

If the exact spreading loss value is not known, an initial value of 30dB is recommended.

Figure 4-20 Spreading

4.3.8 Sound Velocity

When the Override checkbox is checked, the sound velocity slider allows the operator to enter a value for speed of sound in the water.

When a sound velocity sensor is interfaced and the override checkbox is not checked the sound velocity value as displayed will be the value as received from the sensor.


Figure 4-21 Sound velocity with Override checkbox

An online sound velocity must be used for providing up-to-date velocities to ensure optimum performance. A manual velocity may be entered instead but care should be taken to ensure the value entered is representative of the real velocity.

4.3.9 SVP Filter

The sonar uses the value from the sound velocity probe to present the data in the wedge. When there are spikes in the data from the sound velocity probe the display of the sonar data will be disturbed. The SVP filter will filter these spikes out of the data from a light filter (option Light) to normal (option Normal) and a strong filter (option Strong).

Figure 4-22 Sound velocity with Filter set to Normal


4.4 Messages Pane In the Messages pane the operator can see the error messages related to the sensor interfacing.

Figure 4-23 Messages

All the error messages will be displayed in the Messages list. By accepting an error message it will be removed from the list. This will not mean that the error is solved, but that only the message is removed.

Select an error message and click on to remove the selected error message from the list. Click on to remove all error messages.

4.5 Detection Pane In the Detection pane the parameters for the gates enabled/disabled in the Main pane (see page 24) are defined. The gate modes are:

Depth gate

Range gate

Adaptive gate

In the detection pane it is also possible to enable the autopilot range or pulse length.

Figure 4-24 Detection pane

The minimum difference between the minimum and maximum gate value is set to 2m. When one of the gate values is set closer than 2m from the other gate value, the other gate value will change to get a difference of 2m again. This is also valid when one of the gate values is dragged in the Wedge screen (see also Figure 4-26).


4.5.1 Depth Gate

The depth gate will use the minimum and maximum depth values as entered. Only the bottom returns which are within these depth limits will be used in the bottom detection process. Additional a depth gate tilt value can be set

Figure 4-25 Depth gate

The minimum and maximum gate values can also manually be moved in the Wedge screen by dragging them with the mouse.

Figure 4-26 Wedge with depth gates displayed

When the maximum depth gate is out of range of the wedge display, move the cursor to the outer nadir range of the wedge, press the left mouse button (cursor becomes a double arrow), and drag it inside the wedge. This way the maximum depth gate is moved inside the range of the wedge as illustrated in Figure 4-27.

Figure 4-27 Wedge with maximum depth gate not displayed Pointer moved to Nadir outer range of wedge and maximum depth gate dragged back into the wedge.


In case a maximum gate is dragged outside of the wedge range the gate will get the maximum value. (For the depth gate 400m)

Use of a motion sensor is required to rotate the depth gates with the rolling motion of the vessel to ensure soundings are not clipped as the seabed rotates with respect to the sonar.

The depth gate tilt can be used when the seafloor is tilting. Click on the value and use the slider to rotate the depth gate to match the tilt of the seafloor.

Figure 4-28 Depth gate with a depth gate tilt of 0° (left) and 15° (right)

4.5.2 Range Gate

Figure 4-29 Range Gate parameters

The range gate will use the minimum and maximum range values as entered. Only the bottom returns which are within these limits will be used in the bottom detection process.

The minimum and maximum gate values can also manually be moved in the Wedge screen by dragging them with the mouse as the depth gate. (See depth gate)

4.5.3 Adaptive Gate

Figure 4-30 Adaptive gate parameters

The adaptive gate will use the minimum and maximum nadir depth values as entered. It will search for the strongest bottom return from the nadir beam based on the window size.

The nadir search limits can manually be moved in the Wedge screen by dragging them with the mouse.

Use an initial window size of 30%

The window size is used to define the gate limits around the detected seafloor. The distance between the limits and the detected seafloor is the percentage of the detected bottom depth value. The percentage is the entered Window size. Increasing the window size will make the search area bigger so the chance of noise increases. Decreasing the window size with a non-flat seabed will result in a degraded performance.


4.5.4 Autopilot

The Autopilot function is enabled or disabled in the Sonar UI toolbar. See page 13.

Figure 4-31 Autopilot

Based on the quality of the collected data the Autopilot will be able to set the following parameters automatically:

Range

Pulse length

Determine which parameters the autopilot should include by clicking the associated check box.

The autopilot will only adjust the range when the depth is more as 1 meter.


4.6 Display Pane In the Display pane the operator can customize the visual properties of the four screens in Operation mode.

Only the screen(s) selected in the Main pane are available in the display pane.

Figure 4-32 Display pane with Sidescan, Snippets, Water Column and Detect settings


Figure 4-33 Display pane with Wedge items

The Display pane contains settings for each screen. For the Wedge, Water Column, and Detect screens, most of the settings are also available in the context menus (see also Screens on page 47).

The Wedge, Water Column, and Detect screens have in addition to the general settings several “layer” settings with various features which can be displayed in the screen. Each of these layers can be switched on/off and have their own settings for color and font size.


4.7 Recording Pane In the Recording pane the operator set the raw data recording, image and movie recording parameters.

Click on the appropriate button in the SUI toolbar to start raw data recording, start AVI screen recording, or to save a snapshot (See also Sonar UI toolbar on page 13)

Figure 4-34 Recording pane

4.7.1 Sonar Data Recording

In the sonar data recording folder the operator selects what data to record and specify the parameters for the raw data recording.

4.7.2 File storage

When the Single file check box is enabled, a single log file is created. Otherwise the log file will be broken up into smaller parts.

When the History check box is enabled, each file will start with data from the buffered history (currently 10 seconds of data).


Click on ‘Path’ (it becomes blue), and then on ‘…’ (See Figure 4-35) to open a folder dialog box. Browse to the folder where the data are to be saved.

Figure 4-35 Define path.

When starting a recording the filename will be displayed. The file name has the format ‘yyyymmdd_hhmmss.xxx’; with xxx is s7k.

4.7.2.1 Record Selection

All other available records When clicking the check box the record numbers will be displayed at the bottom of the pane in the info box.

The sensor data can only be recorded when these sensors are interfaced with the sonar system. This can be done in the Hardware pane.


4.7.2.2 Compressed Water Column

It is possible to reduce the amount of recorded Water Column Data.by enabling the filter(s):

Remove phase Data

Compress to 8 bits

Remove beyond detection point

The type of downsampling is selectable from the dropdown list to:

None

Middle of Window

Peak Value

Average Value

The downsampling factor for the selected downsampling type is adjustable between a factor of 2 and 10.

Figure 4-37 Compressed Water Column

4.7.2.3 Status

Figure 4-38 Status of raw data recording

The Status of the Sonar Data Recording displays information on the current file size of the recording, the selected data records, recording time left and additional recording information.

By hovering the cursor over the selected records field will display all logged records.

With increased range and/or ping rates, the recording files will become quickly very large. It is best to monitor the file sizes and ensure that 10% of the disk space is always left available for system operation. Therefore it is recommended to record the data on a separate hard disk and not on C:\.

4.7.3 Custom Recording and Playback

With the custom recording function the operator has the option of logging files with a user-defined header and trailer. With the playback function it is possible to play back raw sonar data files.

Custom recording settings are only displayed when the Custom recording checkbox has been selected in the Application Settings dialog’ box. See page 13.


4.7.3.1 Recording Settings

These settings are made on special request of customer(s) to have the possibility of adding a header or trailer to the recorded file(s).

Figure 4-39 Recording

Check the ‘Prepend header’ checkbox when a header name has to be added to the start of the logged record file name

Click the ‘Append trailer’ checkbox when a trailer name has to be added to the end of the logged record file name.

Specify the associated header/trailer file name in the header and/or trailer field.

Figure 4-40 Header and trailer (optional)

When Enable logging is selected the files will be logged in the Directory under File storage. Status of the logging can be monitored under Status.

It is recommended to use an external drive location for logging and not a drive on the PC running MBCenter. Logging data on the MBCenter PC at long ranges or high ping rate may produce incomplete log files.

4.7.3.2 Playback

In the File storage node, select the file to play back:

a. Directory; select the folder where the file is located.

b. File; enter the name of the RAW sonar data file.

In the file playback node:

Play the file once

Loop the file

Advance to next file

b. Click the Enable playback check box to start replaying the file.

c. Click the original timestamps checkbox to use original time stamps. When using original timestamps the file cannot be looped or played more than once. When ‘Advance to next file’ is selected as playback mode the files must be ordered in time. Otherwise an error can occur because possibly the timestamp jumped back in time when replaying more files. If not using original time stamps the current time stamp is used for every ping. The ‘Advance to next file’ mode can be used without the sequence of the files taking into account

4.8.1 Deck mode

Figure 4-43 Deck mode

In Deck mode the transmit power is switched off and the ping rate is lowered to one. Select deck mode when the sonar is out of the water to protect it against damaging the transmitter array.

4.8.2 Port Settings

Figure 4-44 Port Settings

In the Port settings pane, set up the correct baud rate, data bits, parity, and stop bits for the different sensors connected to the RTA box.

After installation of the MB2 software the ports are set by default to 19200Bd, 8 data bits, none parity and 1 stop bit.

For correct bathymetric data, it is essential to apply a clock signal with PPS and sound velocity data.

The appropriate data message formats from the sensors are fixed for a MB2 Odom sonar system. The sensors may be externally connected to the RTA box or optionally integrated in the RTA box. A sound velocity


probe and / or motion sensor may optionally be integrated in the sonar head. Refer to the MB2 Hardware Manual for more details.

Table 1 summarizes the sensors with the required message format.

Use Input distribution (RRIO) ( RESON Remote I/O) to send one of the received sensor data messages to another system, such as an acquisition computer.

Enter as destination address the IP address or computer name followed by colon (:) and a port number (e.g. 7100). For instance: 10.4.1.28:7100.

The port number is the base port. Depending on the source of the message, a fixed offset is automatically applied. Currently this is defined for:

VRU: Base port (e.g. 7100)

Position system: Base port + 2 (e.g. 7102)

Compass: Base port + 4 (e.g. 7104)

Sound velocity: Base port + 6 (e.g. 7106)

External clock: Base port + 8 (e.g. 7108)

Pan and Tilt: Base port + 10 (e.g. 7110)

4.8.4 Sensors

Figure 4-46 Sensors

Optionally an HPR sensor and / or a SVP sensor is installed in the Odom sonar. Select the associated check box when this applies. The SUI will now use these data stream(s).

Both checkboxes are selected by default after installation of the MB2 software.


Refer to Appendix - MB2 Turn-On Procedure with Integrated HPR on page 65 for the proper turn on procedure of the MB2 with a build in HPR.

4.8.5 Input trigger

Figure 4-47 Hardware part for the Trigger Configuration

When the Input trigger is enabled, the ping will occur upon receipt of the input trigger pulse. If the trigger pulse rate exceeds the sonar’s actual maximum ping rate for that range setting, some trigger input pulses may be dropped.

When the trigger input is disabled the sonar will return to ping at the rate dictated by the settings in the Main and Advanced control panes.

Trigger input may be simulated by using CTRL+P on the console for each trigger event.

4.8.6 Sonar mounting

The sonar head may be tilted to a certain angle. Specify the head tilt value in this field.


4.9 Screens In Operation mode, it is possible to display three screens:

The wedge

The Detect or the Water column

The Snippets

The screens can be switched on/off in the Main pane ( see Tile page 26)

When a screen is disabled then no historical data will be logged. This means when enabling a view during acquisition the associated view(s) will start empty.

Figure 4-49 Screens.


4.9.1 Screen Toolbar

All four screens have a toolbar that becomes visible when the cursor is moved over the top left part of each screen. When a screen is too narrow for the toolbar, move over the left side of the screen and the toolbar will be displayed at the left side.

Define how the history is displayed in the Wedge by setting:

History Length: the length of the history in pings.

Swath Shift: the direction of the history in the display.

Swath Spacing: the distance between the swaths.

4.9.4.4 Measurement

When pressing ‘M’ on the keyboard a distance measurement function becomes active. Click in the wedge and drag the cursor to a point to measure the distance between the two points.

Deactivate the measurement function by pressing ‘M’ again.


Figure 4-55 Distance Measurement function.

4.9.5 Water Column

The Water Column screen shows the complete water column for the selected beam.

Figure 4-56 Water Column screen

A beam is selected with the beam selector from the toolbar in the Wedge screen (seeTable 2) or in the Display pane under Water Column (see Figure 4-32).


4.9.6 Detect

The Detect screen shows the bathymetry data of a single swath with different beam data color modes. The swath is displayed in Zoom Extent mode; the vertical scale is enlarged to enhance the details of the swath.

Figure 4-57 Detect screen with one swath

The legend for the Multibeam Data Color Mode (Fixed, Quality, Detection Process, or Uncertainty) is shown in the lower right corner of the screen. This legend (Data Layer) cannot be switched off in the Display.

The grid lines can be switched on/off in the Display pane under Grid Layer (see Figure 4-32).

4.9.7 Sidescan

The Sidescan screen shows an image of the seafloor. It is possible to use this view to locate and identify features and bottom conditions. Each sonar ping is used to generate a line of data. Each line contains a series of amplitudes representing the signal return versus time or range. When a series of these lines is combined and displayed as the vessel moves along the track, a two-dimensional image is formed, providing a detailed picture of the bottom along either side of the vessel.

The sidescan data can be viewed on a waterfall display representing the results of a peak-detect search through the left and right beams of the swath.

Figure 4-58 Sidescan screen

By default the scaling of the data is set on Auto Scaling. Deactivate the Auto button in the toolbar and the operator can manually set the threshold, gain and TVG for the picture in the Sidescan screen.


Sidescan cannot be used to accurately measure true depths, but it can provide a more detailed picture of the seafloor. This image can be used together with bathymetry to identify features and to help ensure that the survey does not miss any small but significant targets.

4.9.8 Snippets

The Snippets screen shows the backscatter data in a waterfall display.

Figure 4-59 Snippets screen

By default the scaling of the data is set to Auto Scaling. Deactivate the

Auto button in the toolbar to be able to manually set the Threshold, Gain, and TVG for the image in the Snippets screen (see Figure 4-51).

A snippets data sample contains corrected backscatter data from the ‘footprint’ on the seabed illuminated by a single sonar ping. The number of snippets in a swath is a function of the number of sonar beams. The length of each snippet depends on the operating mode, beam number, and depth. The snippets window can also be set manually.


Figure 4-60 Snippets data

Each snippets data packet contains pertinent information such as time stamp, sequential ping number, sample rate, sound velocity, and operator settings such as power, gain, absorption, and range scale.

ODOM Sonar UI - User Manual Service 57

5 Service

5.1 Introduction The Service mode in the Sonar UI monitors the status of the complete sonar system; the temperature, communication status, and other parameters.

With the diagram of the sonar system together with the related BITE (Built-In Test Environment) information, it is easy to check if each part of the system is working fine. It is quickly apparent, for instance, if a component, wire, or pin is the cause of an error or warning.

The Service mode is selected in the SUI Toolbar (see Service Mode on page 17).

This chapter will explain how the user can go through the different options to monitor the system or, if necessary, find the reason for the error.

5.2 Diagram

Figure 5-1 Diagram in the Service of a Odom MB2

When the Service mode is selected in the Sonar UI toolbar a diagram is displayed. In the diagram the operator can see directly if the complete sonar system is working fine. All components, wires, and pins should be in blue or green. BITE information is available for the green (and red) components and pins.

Click on the item in the diagram to display the available information on the right side on the Details tab (see page 59).

58 Service ODOM Sonar UI - User Manual

The following colors apply for the components:

Green; status OK

Orange; warning detected

Red; error detected

The following colors apply for the pins:

Green; ok or sensor not used

Red; error detected

Beware of the status of the HPR and SVP pins. When in the hardware pane the sensors ‘Enable build in HPR’ and ‘Enable attached SVP’ checkboxes are off (see page 45) it means these sensors are not used. In this case the build in HPR and Attached SVP pins are green colored.

In case the advanced pane - sound velocity override checkbox is selected (see page 31) it means both the SVP and attached SVP pin are green colored because now both SVP sources are not used.

Figure 5-2 MB2 Center in error (red), RTA in order (green)

Error messages are displayed on the Status tab (see 5.3.1 below). When the error is timed out, the component will be red, but no information will be displayed on the Status tab.

5.3 Information The available information of the sonar system is displayed on the right side in Service mode. The different types of information are arranged under several tabs:

Figure 5-3 Service tabs

Status (see below) On the Status tab the errors with the relevant information are displayed.

Details (see page 59) On the Details page the BITE information of the selected component, wire or pin in the diagram is displayed.

Config On the Config page the preconfigured settings and the serial/version numbers for the software and firmware of the installed sonar system are displayed.


BITE File On the BITE file tab the contents of the BITE file is displayed. This tab is only available after pressing ‘Ctrl+B’ on the keyboard.

5.3.1 Status

On the Status tab the errors or warnings of the system are displayed. When no error or warning occurs, this tab will be empty.

A message will be displayed on the Status tab for each part of the sonar system in error.

Figure 5-4 Example of warning message in the status page

Status tab messages are color coded.

Red LED: error

Yellow LED: warning

Green LED: error/warning solved. The solved error/warning message remains in the list until

removed by clicking .

The error or warning message will also be displayed in the related BITE information on the Details tab (see 5.3.2 below).

In addition to the error/warning itself, the message contains information to assist the operator solve the problem:

The possible cause of the error/warning.

The effect of the problem on the system.

A hint for the operator to understand the problem.

Use to save all information of all tabs to a HTML file. The name of the file will contain the timestamp so successive files won’t overwrite each other.

5.3.2 Details

On the Details tab the BITE information of the selected component, wire, or pin in the diagram will be displayed. Press Ctrl+B on the keyboard to access more information for some items in the diagram.

At the top the name and unique ID of the selected component, wire, or pin is given. Below this the available BITE information is displayed with the actual value or status for each item. The accepted range for each item is displayed between brackets.


Figure 5-5 Example of BITE information on the Details tab

When an error or warning occurs for one of these items a message will be displayed on the Status tab (see 5.3.1 above). On the Details tab the information is also updated as shown in Figure 5-5

Errors and warnings occur when an item exceeds a specified minimum or maximum level and/or exceeds a specified time limit. The error status for each item has an internal error status which is incremented when there is an error and decreased if not. When there are many errors close to each other in time, the error status will increment above 1 and the status goes to ‘Error’. After a while with few or no errors the error status will crawl down and come below 1, the status goes back to ‘Ok’. The tolerance to the errors and the time errors are remembered are controlled by the ‘min’ and ‘max’. So for the error counters the min and max are not just limits used for comparison.

This means that for example an error message occurs when the head FPGA exceeds a certain temperature (level) but also when the PPS pulses are not received (exceed a time limit).


Figure 5-6 Example of timed outs in the MB2 head

When the error message is ‘Timed out’ it means that for a specific number of seconds no information has been received from the system.

5.3.3 IO Module QC

On the IO Module QC tab the data from the different devices interfaced and set up in the Hardware pane are displayed on tabs.

For each device the data string is unpacked and the data is displayed as it is received from the MBCenter 7k message. See Figure 5-7.


Figure 5-7 IO Module QC page with good GPS data

When the message is received correctly, this is indicated by a green colored ‘ok’ status box. See Figure 5-7.


If data from one of the devices is not received properly it is indicated by a red colored ‘time out’ box. See Figure 5-8.

Figure 5-8 IO Module QC page with a timeout on the heading data

The BITE LED on the SUI toolbar will also turn red. See Sonar UI Toolbar on page 13.

The Clock (ZDA) has no corresponding 7k message. This result in a red colored ‘no data’ status box.

Figure 5-9 No Data message for the clock (ZDA)

The status of the message fields are indicated by symbols:

: All items ok


: No data in datablock. (Some device drivers expect a certain data field while it is not outputted by the connected device. It is still possible to use this driver as long the required data field is available.)

: Invalid data; one or more items failed to unpack.

The status indication is with respect to the last received data block. This means the field can still marked as ok while the status box indicates time out. (As it was received previously correct.) See Figure 5-10.

Figure 5-10 Status indication

The raw data received from the MBCenter is displayed at the top of the tab (Figure 5-8). These are the data strings of all the data received on the different ports of the RTA. When a destination address is entered in the Hardware pane for the input distribution (RRIO) (see page 45) all data as displayed in the Raw Data Messages will be outputted.

6.1 MB2 Turn-On Procedure with Integrated HPR

6.1.1 General

The MB2 must be turned on in a proper turn-on sequence if an integrated HPR (Heading Pitch Roll) sensor is installed in an MB2. If this sequence is not honored, the user may experience difficulty getting all serial data stream properly.

6.1.2 Turn-On Procedure

1. Ensure all connections on the rear panel of the RTA:

a. Power;

b. Sonar;

c. Ethernet (connected to TSPU laptop);

d. Primary and Secondary Antennas.

Do not power on the RTA at this stage.

2. Turn on the software (SUI).

3. Ensure proper settings in the SUI:

a. Set all serial port baud rates to 19.2k (defaults) from the Hardware pane – Port Settings folder. Refer to Port Settings on page 44.

b. Select the Use Built in HPR checkbox from the Hardware pane – Sensors folder. Refer to Sensors on page 45.
