1 INTRODUCTION 1.1 Outline of Equipment The R2Sonic Sonic Multibeam Echosounders (MBES) are based on fifth-generation Sonar Architecture that networks all of the modules and embeds the processor and controller in the sonar head’s Receive Module to make for a very simple installation. The Sonic Control Graphical User Interface (GUI) is a simple program that can be installed on any Windows-based computer and allows the surveyor to control the operating parameters of the Sonic MBES.
1.2 How to use this Manual This manual is designed to cover all aspects of the installation and operation of the Sonic MBES. It is, therefore, recommended that the user read through the entire Operation Manual before commencing the installation or use of the equipment. 1.2.1 Standard of Measurement The Metric system of measurement is utilised throughout this manual;...

150MM 3.1 Sonic MBES Receive Module Installation The Sonic MBES sonar head is mounted on the standard R2Sonic mounting frame, as shown below. Figure 8: Sonic 2024 and Sonic 2022 on the mounting frame If the Sonic 2024/2022 sonar head is not pre-mounted, the following guidelines must be followed for proper operation of the system.
3.1.1 Mounting the Sonic MBES Receive Module Sonic 2024/2026 Sonic 2022 Figure 9: Topside of Receive Module Sonic 2024/2026 Sonic 2022 Figure 10: Receive Module Face 3.1.2 Receive Module The Receive Module has two connectors; the female connector is for the Projector cable, the male connector is for the deck lead that goes to the SIM.
New Deck Lead connector 3.1.3 Commencing August 2016, the receiver deck lead connection is being changed from the push-on type to a locking ring design on a short lead (penetrator). Customers can request the push-on connector, if desired, to meet with specialised installations. The receiver end of the cable is not removable as in previous versions;...
3.1.4 New Cable Clamping Arrangement New decklead and projector cable clamping arrangements were introduced in 2017. The cable clamps are designed to further enhance the robustness of the installed sonar head 3.1.4.1 Receiver cable clamp There are two configurations for the decklead connection to the receiver. The standard comprises a single cable with a push-on connector and the penetrator style, where there is a pigtail cable from a moulded connection on the sonar housing.
Figure 18: Sonic 2024; Standard decklead on top; Penetrator decklead on bottom 3.1.4.2 Projector cable clamp The clamp, for the projector cable, is also in two parts. The projector cable clamp replaces one of the projector’s standard standoffs. The projector cable clamp requires an updated projector housing but can be retrofitted to previous projectors at the customer’s request.
Mounting bracket securing bolts pass through the two holes on the edge of the upper block. Figure 20: Upper bracket for Projector cable clamp The lower bracket fits within the upper bracket and is placed under the cable, but not bolted to the projector housing.
Sonic 2024/2026 Sonic 2022 Figure 25: Receive Module with cables connected SV Probe block is secured, via screws, though the underside of the mounting frame Prior to mounting the Receive Module, the block that holds the sound velocity probe must be secured through the underside of the mounting bracket.
3.1.5 Mounting the Sonic 2024/2022 Projector The projector is secured to the frame with two, 35mm Figure 27: Sonic 2024 Projector standoffs. The stand-offs allow room for the Projector to Receive Module cable to be run. A 6mm drive hex screw secures the projector through the stand-off.
3.1.6 Mounting the Sonic 2026 Projector The 2026 Projector is mounted within the same style housing as the receiver and is thus mounted in the same way that the receiver is mounted using the same isolation collars, washers and nuts.
The sonars use water as a means to dissipate heat. Operating the sonar, in air, can do damage to the sonar; to prevent damage, R2Sonic now has a pre- deployment test mode.
3.1.7 Correct Orientation of the Sonic MBES The Sonic MBES is designed to be installed with the projector facing forward, or towards the bow. However, if the installation requires the projector to face aft, in Sonic Control, the user can select the orientation to projector aft and this will re-orientate the data output to reflect the projector orientation.

3.2 Sonar Head Installation Guidelines 3.2.1 Introduction The proper installation of the Sonic MBES sonar head is critical to the quality of data that will be realised from the system. No matter the type of installation (hull mount, moon pool, or over-the- side pole), the head must be in an area of laminar flow over the array.
There are disadvantages to the hull mount: the head cannot be inspected easily for marine growth or damage; the vessel may be restricted in the depth of waters that can be surveyed, due to the head being permanently attached to the hull. A normal hull mount will also involve the fabrication of a fairing, on the hull, to ensure correct flow patterns over the sonar head.

SONAR INTERFACE MODULE (SIM) INSTALLATION and INTERFACING 4.1 Sonar Interface Module (SIM) Figure 35: Sonar Interface Module (SIM) The Sonar Interface Module is the communication centre for the Sonic MBES. The SIM receives commands from Sonic Control 2000 and passes the commands to the sonar head. The SIM also receives the PPS and timing information, which is transferred to the sonar head to accurately time stamp all bathymetry data in the sonar head.
Pass through holes Figure 36: Removal of trim to expose securing holes 4.1.2 Electrical and Interfacing The SIM has four DB-9 male connectors on the front. The label, on the top, clearly shows all connections. Beginning on the left front, the connections are: GPS, Motion, Heading, and Sound Velocity.
Figure 37: SIM Interfacing Physical Connections Figure 38: SIM Interfacing Guide (from the label on top of the SIM) NB. Again, at present, the SIM only takes in the PPS, NMEA Time message, sound velocity (at the sonar head) and motion data, but not heading information. Page 51 of 254 Version r012...

The standard time message is an NMEA sentence identified as $GPZDA and is expected to arrive after the PPS. The time message will also, usually, go to the data collection computer, so the ZDA message must either be split or output on two of the GPS receiver’s RS-232 ports. The $GPZDA and UTC message can be input to the SIM either via serial or Ethernet.

The miniSVS cable is terminated with a female DB-9 RS-232 connector; this is attached to the male DB-9 RS-232 connector, on the SIM, marked SVP. The probe is powered through the SIM’s serial port 12VDC supply.
Sonic Control is supplied on a CD or as an attached file. There is no installation program, merely decompress the program to a folder in a root directory of the computer. Send the R2Sonic.exe to the desktop as a short cut (right-click on R2Sonic.exe and choose to Send to -> Desktop (create shortcut)).
5.3 Settings Menu The Settings Menu provides access to the sonar setup and configuration. Each selection will be detailed. The order of the menu selections is not the order of setup. The initial sonar setup involves establishing communications between the sonar head, Sonic Control, and the SIM.

5.6 Sonar Settings (Hotkey: F2) The Sonic MBES have many features that provide the user with the versatility to tailor the system to any survey project; many of these features can be controlled either through the Operation Settings or with the mouse cursor. Figure 56: Settings Menu Figure 57: Sonar Operation Settings window Page 69 of 254...
5.6.1 Frequency (kHz) 170 kHz – 450 kHz The Sonic MBES operates on a user-selectable frequency, from 170 kHz to 450 kHz (standard with Type 1006 projectors; the Type 1004 projector is limited to 200 kHz to 400 kHz), in 10 kHz steps. The operating frequency can be changed on the fly;...
5.6.1.3 Sonic 2026 Low Frequency Option The Sonic 2026 has a low frequency option, which enables the Sonic 2026 to operate at 90 – 100 kHz for deeper area surveys. The Sonic 2026 uses a completely new projector that is larger than the standard Sonic 2024/2022 projector.
Figure 61: Sector coverage The Sector Coverage can also be controlled via the mouse cursor inside the wedge display. 5.6.3.1 Symmetric sector sizing Position the cursor on either of the straight sides of the wedge; the cursor will change to a double arrow, and the sector can be reduced or increased.
5.6.4 Sector Rotate The Sonic MBES has the capability to direct the selected sector to either port or starboard, allowing the user to map vertical features, or areas of interest, with a high concentration of soundings resulting from the compressed sector. First, change the sector coverage to the desired opening angle;...
A more technical way to look at this is the change over from equidistant to equiangular occurs when the outer beam grazing angle is 80° or greater. This is based on the below equation: (Swath Width / 2) + Head tilt + Sector rotate = grazing angle of the outermost beam Figure 64: Bottom Sampling Modes 5.6.6.1 Dual/Quad Mode The Dual/Quad bottom sampling modes can be used with both equiangular and equidistant...
1024 soundings per ping. As opposed to producing pseudo beams by interpolating data to create the appearance of double the beams; R2Sonic searches across each beam footprint for additional soundings, using the extra-fine angular resolution that results from R2Sonic’s advanced signal processing to precisely locate each point.
Page 76
density and detail based on the acoustical properties of the bottom return acoustic signal = up to 1024 real bottom soundings. When operating in UHD mode, the data collection software storage files can become large with the additional soundings, and it is recommended to use the data collection software file splitting routines.
5.6.8 Mission Mode The versatility, built into the Sonic 2026/2024/2022 systems, is further enhanced with the ability to adapt the system to the nature of the survey task: normal survey, surveying a vertical feature, or the optional Forward Looking Sonar mode.
Figure 70: Enable Acoustic Image in the wedge display 5.6.9.2 Forward Looking Sonar (Sonic 2024/2022-Requires Type 1004 projector) Forward looking mode can be in one of two configurations. FLS Wide uses the 20° projector within the Type 1004 projector. FLS Narrow uses the 1° standard projector. The wide mode, using the 20° projector, will have a lower source level, but is very good for near field use.
Because of these advanced features, with the Sonic 2026 and Sonic 2020 FLS mode, there is an additional FLS option in the Settings menu that allows the user to set the Vertical Beamwidth and the degree of Vertical Steering.
Approximate Vertical Beamwidth in Degrees Setting Narrow Wide Default Table 14: Sonic 2020/2026 FLS Vertical Beamwidth As an example of the vertical steering: 400 kHz, the steering is ±10°. At 200 kHz, the steering is ± 20°. Page 80 of 254 Version...
5.6.11 Dual Head Mode (Also see Appendix VII, Section 13.9) The selections are Single Head, Simultaneous Ping or Alternating Ping. When the dual head mode is selected, a second wedge display will be available in Sonic Control 2000. When using dual heads, the sonar heads have to have exactly the same firmware installed. Use the Status display to verify that both heads have the same firmware;...

Side scan records are: •...
(NIC) settings are very important to allow the computer to work with water column data collection. There are also Windows Registry settings that can be adjusted; please contact r2support@r2sonic.com for details on changing Registry settings. The NIC has to be Gigabit. It is very important to increase the Receive Buffer size, for the NIC, so that the NIC can handle the flow of the data.
First introduced in 2016, the MultiSpectral mode provides a means to ping at different frequencies with each subsequent ping. R2Sonic has greatly enhanced the ability to tune the sonar on a ping to ping basis beyond just the frequency. The MultiSpectral mode is now a selection in a more enhanced MultiMode function.
When loading a configuration, from the Presets, the user will be notified that the current settings are about to overwritten. Figure 89: Preset warning Under ‘Mission Mode’ there are preset options that can be used as a starting point or two Custom settings, which can be renamed by selecting the ‘Rename Mode’...
Page 88
sonar is put to 700kHz and the power adjusted for that frequency. If this is not done, it could be the Power setting may be too low for 700kHz, and the result will be noise instead of a good bottom return.
5.8 Ocean Setting Figure 94: Ocean Characteristics Ocean Characteristics include Absorption and Spreading loss, which are the main components of the Time Variable Gain (TVG) computation, and manual Sound Velocity (for receive beam steering). 5.8.1 Absorption: 0 – 200 dB/km Absorption is influenced primarily by frequency and the chemical compounds of boric acid B(OH) and magnesium sulphate MgSO in the water column.
NB. In very shallow water (2m or less) it may be more advantageous to use Fixed Gain. To put the system into Fixed Gain, enter zero (0) for both Spreading Loss and Absorption. For more detailed information on absorption and spreading loss, please refer to Appendix VI Basic Acoustic Theory.
Page 91
5.8.3.1 TVG Curve The TVG curve can be either shallow or steep, depending mostly on the Absorption value to define the shape of the curve. The Spreading Loss will determine the amplitude of the gain. Figure 95: TVG Curve Concept 5.8.3.2 Sound Velocity The speed of sound, at the receiver’s face, is required to do the receive beam steering, which is required for all flat array sonars.
Page 92
WARNING The wrong sound velocity, at the sonar head, will cause erroneous data. There are currently no known post-processing tools to correct for this. If the sound velocity is wrong, the beam steering will be in error. If the sound velocity is greater than what it really is at the face of the receiver, the ranges will be shorter, and thus the bottom will curve up or ‘smile’.
Z offset of 0.119m for the Sonic 2024 and 2022 and 0.045m for the Sonic 2026 being the default. If the projector is not mounted in the same vertical relationship to the receive array, an offset can be entered here to compensate for that vertical offset. If the box is checked, Sonic Control will automatically choose the correct Projector Z offset for the system.
5.10 Status Figure 98: Status Options The INS monitor is covered in Appendix I 5.10.1 System Status The Status report provides a detailed list of the current system parameters in both the sonar head and the SIM, including the current version of installed firmware and serial input messages. It is quite normal that the SIM messages, in the Head Status, differ slightly from the Serial port sensor data (in the SIM Status).
The Saturation Monitor provides the user with the means of monitoring the sonar’s receiver signal level. The Saturation Monitor was developed by R2Sonic based on the work and input of Dr Jonathan Beaudoin (then with Centre for Coastal Mapping, University of New Hampshire).
5.10.3 TruePix™ Monitor The TruePix monitor has been added to Sonic Control to provide users with a means to visualise the real-time imagery. It is important to note that with the addition of the TruePix monitor the manner in which TruePix are transmitted, from the head, has changed. TruePix data will only flow to the data collection software when Sonic Control is open.

The general guideline is to maintain as short a pulse width as possible to optimise the resolution, but not so short as to weaken the transmit pulse.

6 SONIC MBES THEORY OF OPERATION The Sonic MBES transmits a shaped continuous wave pulse at the user-selected frequency. The transmit pulse is narrow in the alongtrack direction, but very wide in the across-track direction. The reflected acoustic energy is received via the Sonic MBES receivers; within the Receive Module the beams are formed, and the bottom detection process takes place.
The across-track angle is 160°; the along-track angle depends on frequency. The 450 kHz along-track pattern is 0.9° (0.5° for the Sonic 2026). The along-track lengthens out to 2° at 200 kHz. This is the Normal Operating Mode and not extended Vertical Mapping Mode.
6.3 Sonic MBES Receive (Normal Operation Mode) The Projector is comprised of composite ceramics that convert electrical energy to acoustic energy. The composite ceramics, in the Receive Module, convert the reflected acoustic energy back to electrical energy. The small electrical voltage, generated by the ceramics, is amplified and then passed onto the receivers.

POS/MV; that information is found in the Applanix POS/MV manual. The information provided here covers the necessary setup of the R2Sonic I2NS components as relates to the R2Sonic SIM and Sonic Control. Where necessary, certain steps in the POSView software are detailed.
7.1.1 Type 82 IMU In March 2021, R2Sonic updated the IMU portion of the I2NS. The updated IMU housing has Type82 etched along one side. The IMU offsets for the Type82 are the same horizontally, but the vertical offset is shifted upwards by 12.1mm.
7.2 Connection diagram When using the INS, there is no need to provide inputs for the motion or the time stamp, as those are provided internally through the SIM’s Gigabit switch. The only serial connection is the sound velocity probe that is on the sonar head. A PPS loop cable is required to go from the PPS out to the PPS in.
7.3 Installation 7.3.1 The IMU and GPS antennas The IMU (Inertial Measurement Unit) housing should be secured by 4 M8 (5/16” in Imperial units) screws. The IMU housing is depth rated to 15m. The IMU can be mounted close to or on the Multibeam transducer itself.
7.3.3 I2NS DB9 Connections The I2NS has two serial communication ports and one dedicated to the internal GNSS board. The two com ports are standard DB9M serial connections that are set up in the POSView software. Both ports are bi-directional and can be configured to receive RTCM corrections or to output standard NMEA or binary serial data.

APPENDIX II: Multibeam Survey Suite Components 8 APPENDIX II: Multibeam Survey Suite Components 8.1 Auxiliary Sensors and Components A multibeam survey system is comprised of more components than just the Sonic Multibeam Echosounder. These components are the auxiliary sensors, which are required to provide the necessary information for a multibeam survey.
during survey operations. If mounting the antenna on a vessel that has helicopter landing facilities, coordinate the placement of the antenna with the personnel in charge of helicopter operations. When the location for the antennae has been determined, the next step is determining how the coaxial cable, connecting the antenna and the receiver, is to be run.

If possible, the vessel will be berthed alongside a quay or dock that has a survey • benchmark located nearby. • If a survey benchmark is not located close to the berth, then the surveyor will have to run a transit from the nearest, suitable, local survey benchmark to establish a point on the quay that has a well-defined position.

8.3.1.2 Tape and Offset Method of Gyro Calibration This method relies on measuring the offset distance from a baseline on the quay, with a known azimuth, to a baseline that is established on the vessel.

8.4 The Motion Sensor The motion sensor is used to determine the attitude of the vessel in terms of pitch, roll and heave. Pitch is the movement of the bow going up and down. Roll is the movement of the port and starboard side going up and down.
The motion sensor should be mounted on as level a platform as possible. After mounting the motion sensor, the actual 'mounting angles' should be measured. Some motion sensors contain internal programs that can measure the mounting angles. Some data collection software packages also include the capability to measure mounting angles.
The CTD and Time of Flight probes store the data internally. The data is downloaded to a computer after the probe is recovered. 8.5.1 CTD Probes The CTD probe type of sound velocity probe has instruments to measure the conductivity of the water, water temperature, and a pressure sensor to measure depth.
8.5.2 Time of Flight Probe The Time of Flight probe incorporates a transducer that transmits an acoustic pulse that reflects back from a plate that it is at a very precise distance from the transducer. The two-way travel time is measured, divided by 2, and the sound velocity determined. The Time of Flight probe is usually considered more accurate for multibeam survey work.
and are used extensively by Navy and Defence forces for rapid determination of the sound velocity without stopping the vessel. 8.6 The sound velocity cast There are no set rules for when to take a measurement of the water column sound velocity. Common sense is a good guideline.

Page 152
Figure 172: Deploying a sound velocity probe via a winch or A-Frame The other major consideration, when deploying a probe in deeper water, is that the vessel must be stationary longer and will drift. If there is a large variation in depths, the depth where the probe went in, may not be the same depth when the probe reaches the bottom.
APPENDIX III: Multibeam Surveying 9 APPENDIX III: Multibeam Surveying 9.1 Introduction Multibeam surveying affords the surveyor with many advantages, but it also requires more thought behind the survey itself. 9.2 Survey Design Multibeam surveying survey planning is very different than single beam survey planning. The main considerations are line spacing and line direction.
slope is within the port or starboard swath coverage. There will be a poor definition of the slope covered by the nadir beams, as they act similar to a single beam echo sounder. In setting up the survey lines, if the lines were to run up and downslope, the spacing would have to vary between the start and the end of the lines, as the swath coverage would vary due to the change in water depth.
The vessel record is meant to be a quick reference for general information that is required for multibeam surveying. Some of the information does not change from survey to survey and should go either in the front of the book or the back of the book. A section of pages can then be devoted to the information that does change from survey to survey or day to day.

any temporary list the vessel is experiencing. On small survey vessels, a person leaning over the side, to take the draft measurement, can induce upwards, or exceeding a 10cm error in depth readings during survey operation. On some vessels, it is advisable to take draft readings during the survey or immediately after completion of the survey, as the draft will change that much.
APPENDIX V: The Patch Test 11 APPENDIX V: The Patch Test 11.1 Introduction The alignment of the Sonic MBES sonar head to the motion sensor and gyro is critical to the accuracy of the determined depths. It is not possible to install the sonar head in exact alignment with the motion sensor and gyro to the accuracy required (x.xx°).
11.3 Patch Test Criteria The patch test requires collecting sounding data over two distinct types of seafloor topography; a flat bottom is used for the roll computation whereas a steep slope or feature is used for the latency, pitch, and yaw data collection. Care must be taken that the sonar head covers the same area on both data collection runs, this may not be the same as vessel position, especially with an over-the-side mount or if the sonar head rotated.
11.3.2 Roll Test The data collection for roll has to be over a flat seafloor. One line is surveyed twice, in reciprocal directions and at survey speed. When the data, from the two data collections, are looked at in profile, there will be two seafloors sloped in opposite directions.
11.3.3 Pitch Test The pitch data collection is over the same type of seafloor as the latency data collection, i.e. steep slope or feature on the seafloor. One line is surveyed, twice, in reciprocal directions at survey speed. It is very critical that the sonar head passes over the same exact part of the slope on each run. A profile of the data will show two different slopes, which represent the reciprocal data collections.
11.3.4 Yaw Test The yaw data collection and subsequent solving for the yaw offset is usually the most difficult of the 4 tests that comprise a patch test. This is especially true if a slope is used for the yaw computation; a feature generally works much better.
Position Error with a Heading Error of 1.0° Water Depth 200 metres 150 metres 100metre -100 50 metre 25 metres 10 metres Angle from Nadir Graph 4: Along-track position error caused by 1.0° error in yaw patch test error 11.4 Solving for the Patch Test Depending on the data collection software that is employed and how it solves for the patch test, there will be a distinct order that the tests will be solved for, but this does not influence the data collection for the patch test.
11.6 Basic data collection criteria Patch test data collection does not have to be in any set order, but the order that the values are computed, in the data collection or processing software, will be in a distinct order. Normally, Latency is the first value that is computed, followed by Roll, Pitch and Yaw (or heading).
11.7.3 Water depth The deeper the water, the better the result. In shallow water, DGPS wobble creates more, relatively severe, position errors. A corollary to this is that the subtended angle is proportionally larger in shallow water, which can blur the definition of the object used, be it a feature or slope.
11.8 Improving the Patch Test and Patch Test results Section 11.7 described areas that should be addressed to improve the results of the patch test when collecting the data. Further improvement will come with the number of data collections and the manner in which the patch test is computed. 11.8.1 Need to collect sufficient data Too many times, surveyors will collect just a few lines of data for each test.
11.8.2 Individually solving values No matter what the solving order may be, each value should be computed independently. All tests should be based on the mean of the previous test(s). It is important to understand why a certain solving order is used in all survey software. Each computation is based on the previous test result.
APPENDIX VI: Basic Acoustic Theory Figure 183: In 1822 Daniel Colloden measuring velocity in Lake Geneva (Daniel Colloden used an underwater bell to calculate the speed of sound underwater in Lake Geneva, Switzerland at 1435 m/Sec, which is very close to recent measurements) 12 APPENDIX VI: Basic Acoustic Theory 12.1 Introduction With multibeam, as with any echosounder, the main concern is sound in water.
Page 174
Figure 184: Concept of refraction due to different sound velocities in the water column The velocity of sound in water varies both horizontally and vertically. It cannot be assumed that the velocity of sound in the water column remains constant over large areas or throughout the day in a more local area.
12.2.1 Salinity Generally, salinity ranges from 32 – 38 parts per thousand (ppt) in ocean water. A change in salinity will create density changes, which affect the velocity of sound. As a general rule, a change in salinity of only 1 ppt can cause a sound velocity change of 1.4m/sec. There are many influences on the salinity concentration in seawater.
12.3 Transmission Losses The transmission of an acoustic pulse is generally called a ‘ping’. When the projector sends out the acoustic pulse, many factors operate on that pulse as it moves through the water column to the bottom and also on its return upward. The major influence of the water column sound velocity characteristics was detailed above;...

12.3.4 Reverberation and Scattering The sea is not homogenous in nature. Everything from suspended dust particles to fish, from the sea surface to the seafloor, will scatter, that is reradiate the acoustic energy. All of the effects of individual scattering can be termed reverberation. The effect of reverberation is to lessen the acoustic energy, and this leads to transmission losses.
Appendix VII ROV and AUV Installation 13 APPENDIX VII: Sonic MBES Mounting: Sub-Surface (ROV/AUV) 13.1 Installation Considerations A 1000BASE-T link (best time sync accuracy) is preferred; however, with bathymetry only • information, 100BASE-T will work. 10BASE-T will also work but is not recommended. Bathy data requires 2 Mb/s data rate at a maximum ping rate of 60 pings/sec.
13.1.1 Ethernet wiring considerations The sonar head and SIM use Gigabit Ethernet ports. There are rules regarding the number of twisted pairs, between different Ethernet ports, these rules are: Gigabit to Gigabit • Need all four pairs. If only two pairs used, in an attempt to force the ports to 100BASE-T, the ports will not negotiate, and the result will be no connection.

In an ROV or AUV installation, the sonar head and SIM Controller board require 48VDC, supplied by the vehicle power system. During the receive cycle, the power required is 55 watts for the 2026, 50W for the 2024, and 35 watts for the 2022. The peak current draw occurs just after transmission when the capacitor bank recharges.

13.9 Dual Sonar Head 13.9.1 Dual Head Installation The R2Sonic family of multibeams can be installed in a dual head configuration, either pointing inwards or directed outwardly, depending on the customer’s survey task. In dual head mode, the individual sonar heads can either ping simultaneously (with frequency offset) or alternate pings (same frequency).
Page 200
13.9.2.2 Dual Head – Same Frequency – Alternating ping To operate the dual sonar heads on the same frequency, it is necessary to coordinate the transmit and receive periods, so there is no interference. Operating in the ‘Ping-Pong’ mode will halve the ping rate for each head, but the user gains identical acoustic resolution (such as backscatter) for both sonar heads.

IP address. The ConfigID received from the sonar head and SIM should be compared with the ConfigID number sent to the sonar head and SIM during IP configuration. If there is a mismatch, the control program should send IP configuration data to the sonar head and/or SIM to correct the issue. struct R2DS // R2Sonic Device Status u32 PacketName; // 'R2DS' C structure of Device Status packet u32 SerialNumber[3];...
Using Wireshark, uplink data from the sonar head can be captured, filtered, and saved. Bit Twist, a console application, allows you to playback data. R2Sonic can supply sample Ethernet captures of the sonar head uplink data. You may need to edit the destination MAC and IP addresses of the captured data with Bit-Twiste, a console application.
Figure 213: Wireshark Capture Options This will reduce the processing load on Wireshark significantly. •After capture, filter the data so only the desired sonar head data is displayed. A filter expression like “not(icmp.type == 3 or ip.src == 10.0.1.102)” can be used to filter data coming from the data acquisition computer. •Save using Save As, data type as “Wireshark/tcpdump/…- libpcap (*.pcap,*.cap)”...
Newer Ethernet playback utilities are better than bittwist. Ask support about a modified version of Playcap.exe (Open Source program modified for looping) and Wireplay.exe (R2Sonic program that can play back pcap files at full speed and you don't need to edit pcap files with bitttwiste).
