3 INSTALLATION

3.1 System Overview

The Pinger SBP dry end is a “black box” echosounder that interfaces to any Windows-based PC to allow the user to control all systemparameters, manage peripherals, record entire echogram data, as well as internal and external data logging. The communication linkfrom the Pinger SBP to the PC is via USB (full speed 2.0).

3.2 Software Installation

A CD-ROM is provided with the system which installs the software necessary to control the echosounder as well as other supportutilities, hardware drivers, and documentation files. The CD-ROM should auto-run but if it does not simply run the SounderSetup.exefile located on the disk. This will initiate the SounderSuite-USB installation wizard which will guide the user through the rest of thesoftware installation process.

For a more detailed explanation of the entire software installation please refer to the following manual:SounderSuite - USB Windows Installation and Firmware Upgrades (part number D101-04383)

3.3 Side Connector Panel Overview

3.3.1 Input Power

The echosounder portion of the Pinger SBP needs to be powered from a DC source; the input voltage range is 12-30VDC (nominal24VDC). To eliminate the potential for issues due to inadequate input power, an appropriate VAC to VDC converter is supplied withthe Pinger SBP package.

3.3.2 Transducer Connections

All transducer connections (low frequency transmit, low frequency receive, high frequency) are made through a single umbilical andconnector. RX/TX is a 10 pin connection used for all wet end to dry end signals. Refer to section 6 for pin-out details.

3.3.3 USB Interface

The USB interface provides communication from the Pinger SBP to the PC. It is a full speed 2.0 (12Mbps) connection.

3.4 Inside Panel Overview

3.4.1 Power Switch

The power switch is a covered switch which when locked in the active position will pass the input voltage to the internal modules;the switch is illuminated when active. When it is in the deactivated position, power to the internal modules will be terminated.

3.4.2 Circuit Breaker

Along side the power switch, there is a circuit breaker for intended additional system protection.

3.4.3 SBP/BATHY Switch

The Pinger system is equipped with an SBP/Bathy switch that can be toggled at the dry-end inside panel. The standard operationalmode for the Pinger with the PVDF array is with the switch set to SBP. When the switch is set to Bathy mode, the PVDF receiveris bypassed and the received signal comes via the transducer as is standard in normal survey systems. The advantage of the separate


D101-05326-Rev1.3 May 13, 2013 5 of 13

receive array in SBP mode is most apparent in shallow water conditions where the ringing of the transducer in normal bathyoperations would overpower and mask the desired sub-bottom details. The SBP mode through the PVDF has also been equipped withadditional signal amplification to provide stronger signal levels to pull out weak layers in the sub-bottom details.

3.5 System Connection

3.5.1 Peripherals

All peripherals such as GPS and heave are connected directly to the PC and the setup for each is performed via the EchoControlClient software application.

3.5.2 Data Logging

Same as the peripherals, any connection to an external data logger is done through the PC. There also is the capability to run the datalogging package on the same PC as your EchoControl software.

3.6 Transducer Installation

The correct transducer installation is essential to maintain good system performance. The Pinger SBP wet end assembly has beendesigned for over-the-side installation; it is not intended to be deployed as a towed fish.

3.6.1 Over-the-Side Mount

The method of mounting the transducer over the side of the boat is primarily used for temporary installations. This entails thetransducer mounted to the end of a pole that is fastened to the side of the boat. The transducer array includes a mounting adapter; thelonger pipe and the means to fasten it to the boat are not provided as they change with every installation. It is very important that thetransducer array be completely submerged below the water surface at all times.

3.6.2 Swapping Frequencies

The Pinger SBP transducer array will come pre-assembled with one of the two low frequency transducer assemblies already installed.See Appendix A for the illustration, D111-05321 SBP - Front End Assembly Removal , which provides a breakdown of the stepsnecessary to remove this original assembly allowing for the installation of the alternate assembly. Note: the frequency used in thesoftware will need to be adjusted to match the frequency of the transducer in use. See Section 4.4 for more information regarding howto setup the desired frequency settings.

4 SYSTEM OPERATION

Once the software installation process has been completed, the PC should automatically recognize the Pinger SBP upon power up.The SounderSuite installation CD will have installed application shortcuts for the main EchoControl software onto the desktop ofthe PC for easy accessibility. Normally, the EchoControl Client application should be able to auto-run the required EchoControlServer application; when the Server application is started and running, a red “K’ will appear in the task bar. If the EchoControl Clientfails to auto-run the Server properly, shut the client down, start the EchoControl Server manually via its icon, then start theEchoControl Client which should now be able to connect to the Server properly.

For a complete explanation on the operation of the EchoControl Server and EchoControl Client please refer to the following softwaremanual components: SounderSuite - USB EchoControl Client (part number D101-04380) and Sounder Suite-USB EchoControlServer (part number D101-04381)

4.1 Factory Setup

The Pinger SBP features a frequency agile channel (CH2) that the user can configure to support the appropriate low frequencytransducer installed. The initial frequency should have been preset at the factory to match the low frequency transducer assemblyinitially installed in the transducer array. This frequency can be adjusted as necessary to match the low frequency assembly actuallyin use in the array. The high frequency channel (CH1) will have been preset at the factory to match the 200kHz transducer.

4.2 Channel Roles

The high and low frequency channels operate together but in two different operational roles. The high frequency channel is used todetermine the depth of the bottom return with little interest in the sub-bottom detail. The low frequency channel, on the other hand,is very interested in the sub-bottom detail. As a result of their different roles, their operational control settings are slightly differentto allow them to operate optimally in their specific roles. The distinction between the setting differences is highlighted in thefollowing sections.

4.3 Basic Operation

The EchoControl software provides access to numerous controls for system control, peripheral interfaces, data recording, and real-time data display. The following section defines the usage of the main system operational controls. For a complete explanation ofall EchoControl Client controls please refer to the following manual: SounderSuite - USB EchoControl Client (part number D101-04380)

NOTE: The following discussion assumes operations will be in shallow water depths of less than 200m. If the water depth is greaterthan 200m, the high frequency channel will not be able to operate effectively due to excessive signal attenuation within the watercolumn.

4.3.1 Control Definitions

Tx Power: controls the amount of power used for the outgoing transmit pulse. There are four settings with incremental steps ofapproximately 25% of the total maximum power level.

Tx Pulselength: controls the duration of the outgoing transmit pulse. The low frequency channel can output up to 64ms; the highfrequency can output up to 4ms.

Tx Blanking: controls where the depth digitization algorithm starts to look for a return echo. This should be set deep enough to lookpast any transducer ringing that may be misidentified as a return echo and improperly tracked as the bottom.

Analog Gain: controls the analog gain of the receiver circuitry.

Digital Gain: scale factor applied during the digital signal processing

AGC: automatic gain control - any algorithm that adjusts the analog gain on a ping-by-ping basis based on previous data


D101-05326-Rev1.3 May 13, 2013 7 of 13

TVG: Time-varied gain curves that adjust the analog gain in use during a single ping acquisition cycle

Range: determines size of the active window

4.3.2 High Frequency Channel - Depth Detection

As mentioned previously, the high frequency channel is use for basic depth detection of the bottom location with no interest in thesub-bottom details.

To get the channel to acquire the bottom, the minimum Tx Power and Pulselength needed to determine a bottom should be used. Inshallow water, lower power and shorter pulselengths are typically adequate to get a reasonable bottom return. As the depth increases,the power and pulselength should be increased as needed to maintain the return echo.

AGC is recommended for this channel, used in combination with Processing Shift for the best results. If the AGC algorithm is havingto adjust the gain level to values above 40dB, Processing Shift should be increased until the analog gain level is reduced. This is toprevent over driving of the analog front end and saturation of the receive signal.

Tx Blanking should be set deep enough for the digitization algorithm to see past the transmit pulse and any transducer ringing thatmay be present. The duration of the pulse and any ringing present should be clear from the echogram chart and the Tx Blanking canbe adjusted accordingly.

4.3.3 Low Frequency Channel - Sub-bottom Profiling

Because the low frequency sub-profiling channel actually is interested in the sub-bottom details, unlike the high frequency depthdetection channel, the optimal control settings tend to be quite different for the low frequency than for the high frequency.

For sub-bottom profiling, it is desirable to use the longest pulselength possible for the water depth. Assuming a speed of sound settingof 1500m/s, the minimum depth for the standard available pulselengths would be:

For a 4ms pulse, min depth = 3mFor a 8ms pulse, min depth = 6mFor a 16ms pulse, min depth = 12mFor a 32ms pulse, min depth = 24mFor a 64ms pulse, min depth = 48m

The longer the pulselength, the more energy in the water column and the better the penetration into the sub-bottom.

Using this argument, it would be assumed that the higher the transmit power the better as well but the user does need to take care notto increase the power too high or it is possible to have too much signal in the water column. Too much signal strength could causesaturation of the receive echo which would impair the post-processing analysis of the recorded echogram data. If more signal strengthis required, pulselength should be adjusted first, taking into consideration the minimum allowable depths noted previously, then thetransmit power should be adjusted.

Whereas AGC is recommended for the high frequency depth detection channel, it is not recommended for the sub-bottom profilingchannel. It can be used initially along with the Processing Shift to determine a starting reference for both the manual Rx Gain settingand the Processing Shift setting. Once a preliminary starting point has been determined though, AGC should be disabled so that theuser can then finetune manual gain and processing shift. The goal is to find a combination of Rx Gain and Processing Shift that pullsout the sub-bottom details without pushing either so high as to cause saturation of the receive signal (signal levels so high they getclipped). Another gain tool to help pull out sub-bottom detail is TVG; experimentation will determine the best results for theparticular sub-bottom scenario. Again the goal is pull out more sub-bottom detail but not at the expense of saturating any of the sub-bottom echoes.

To ensure receive signal saturation is not occurring, set the display contrast to zero and observe the return echo levels on the narrowmini-scope display on the right-hand side of the chart display. As long as these levels are not squared off or clipped, the echogramdata is not being saturated. Please note that saturation of the transmit signal is to be expected; the key is to not saturate the returnechoes. Once it is clear saturation is not an issue, the display contrast can be increased if a darker display chart presentation is desired


D101-05326-Rev1.3 May 13, 2013 8 of 13

in real-time. Please note that the echogram data being recorded can be post-processed in third party software to improve its visualappearance as long as the real-time data acquired is not saturated and clipped.

With regards to data recording, the optimal format to record for post-processing of the sub-bottom data is SEG-Y. To be allowed torecord SEG-Y, the channel has to be setup to output one of three carrier data formats. The recommended format is Filtered Carrierand the default Signal control settings have this format enabled by default.

4.4 Swapping the Low Frequency

Whenever the low frequency transducer assembly has to be exchanged, the operational frequency in the EchoControl software mustbe changed to match the hardware. This can be done via the Signal Controls accessible from the EchoControl Client menu. Thefollowing setting combinations are based on in-field trials:

3.5kHz transducer assembly: Frequency = 4kHz, Bandwidth = 6kHz for a chirp sweep of 2 to 8kHz

15 kHz transducer assembly: Frequency = 14.1kHz, Bandwidth = 10kHz for a chirp sweep of 10 to 20kHz

(Please note that the sweep is computed using a geometric passband which results in the start and stop frequencies as indicatedabove.)

The user can experiment with various combinations of frequency and bandwidth if desired. These are suggested settings based onsystems field trials done to date.
