Page 7: Features Of Iclisten Af
2 Features of icListen AF The icListen AF combines high signal integrity, data storage capacity, low power and small size with the ability to process sound data in real-time. The icListen AF can be used in a tethered mode, or as an acoustic data logger. -

3. Click the icListen Setup button in the lower right. In the popup window, select the Link tab and chose the appropriate connection type. To find your icListen, click “Find All Units”. To connect, double click the unit from the found units list. Figure 3-1: Lucy Ethernet connection display icListen AF User Guide © December, 2017... -

5. The humidity is an indication of the seal quality. A humidity reading of 50% or less is acceptable. Higher readings indicate a possible leak in the seal. Contact Ocean Sonics if the humidity is higher than 80%. Close the Setup window if it is still open. -

5.1.2 Stored WAV Data Waveform data may also be stored by icListen AF in standard uncompressed WAV files. This makes data recorded by icListen readable by many third-party sound editing programs and analysis tools, as well as by Ocean Sonics’... -
Page 13: Gain
“clipping” of the signal if gain were applied. icListen AF samples waveform data at 24bits, and makes use of gain to allow access to the low 8bits of data which would otherwise be lost when returning only 16bits. -
Page 14: Power Spectrum (Fft) Data
5.2.2 Stored FFT Data icListen AF is capable of storing processed power spectrum data in tab-separated values format TXT files. These files can be read by virtually any spreadsheet or text editor program. Storing spectrum data can provide a much more compact form of data storage than waveform data, allowing for faster data retrieval and analysis, and means that the unit can store data for longer periods of time between data retrievals. -

Hann windowing operation. The figures below show an example waveform data set, divided into sections which are used to compute frequency data. These figures show the data used with no overlap (0%) and 50% overlap. icListen AF uses a 50% overlap for all spectrum data. - Page 16 ( �� − 1 ) × �� + |�� ��,��−1 ��,�� �� ��,�� �� Where: N = Weighting Factor = Signal Power of frequency bin = FFT Coefficient i = Frequency Bin Number j = FFT Data Set Number icListen AF User Guide © December, 2017...

Page 17: Epoch Mode
Detection of the next trigger event will not begin until the post-event duration has elapsed (and therefore no new messages will be sent for this trigger during this time). All streamed epoch messages are also logged internally on the instrument. icListen AF User Guide © December, 2017... -
Page 18: Logging Start Time
5.4 Logging Start Time icListen AF can be configured to start logging data at a specific date/time. Configuring a start time allows a deployment to be set up well in advance of an actual testing/monitoring session, without unwanted data being logged during this time. Until the start time has been reached, no waveform (WAV files) or frequency spectrum (TXT files) will be logged, but live data can still be transmitted from the instrument. -

6.3 Battery Monitoring icListen AF monitors the charge and state of the internal battery. This allows a user both to know when the batteries have been fully charged, estimate how long the icListen will run from the internal battery, and can be used to determine if there are any issues with the battery. -
Page 20: Wake From Standby
AF is also capable of having its time of day set over the command & control connection to the device. This can be done using Ocean Sonics’ Lucy software or using the web interface, to synchronize to the time on your PC. -

6.8 Low Power -12V Operation As of hardware release 5, icListen AF supports a -12V mode, in addition to the regular 24V mode of operation. This mode saves power by disconnecting the internal battery and associated control circuitry. Due to the lack of internal batteries, when power is removed the unit is immediately shut down when the -12V supply is removed. -
Page 22: Logged Data Retrieval
7 Logged Data Retrieval Data logged in an icListen AF can be retrieved by several different methods: FTP: FTP is the fastest method of retrieving data files. This is typically done using a program such as “FileZilla”. There is no user name or password required when using FTP. This method is used by Ocean Sonics’... -

8 Standard Operation Procedures (SOPs) The following procedures help to minimize the chance of human error while using icListen. These procedures have been designed for use with Ocean Sonics’ Lucy software. icListen AF User Guide © December, 2017... -
Page 24: Autonomous Data Logger Deployment
8.1 Autonomous Data Logger Deployment This procedure is used when deploying an Ethernet icListen AF as a data logger. In this setup, the icListen logs data internally while being powered by a battery (the internal battery, or an external battery may be used). -
Page 25: Autonomous Data Logger Data Recovery
8.2 Autonomous Data Logger Data Recovery This procedure is used when retrieving data from an Ethernet icListen AF deployed as a data logger. Upon retrieval, the icListen should contain stored WAV and/or TXT log data. This procedure requires access to: •... -
Page 26: Care And Maintenance
WARNING: Applying firmware updates will cause all logged WAV, TXT and Epoch data to be erased from the instrument. Updates for icListen AF (Ethernet/SLIP Enabled) are applied using FTP, SCP or SFTP. Ocean Sonics’ Lucy software or any FTP client (such as FileZilla) may be used for this. When using SFTP or SCP, connect to port 22, use “icListen”... -

1. Power the icListen using the power adapter (do not power from battery). 2. Connect to icListen via FTP. If the IP address of the hydrophone is not known, Ocean Sonics’ Marco software can be used to find it. -
Page 28: Connector Care
This will help reduce running down of the battery and accidentally logging data while in storage. Failure to do this can result in lost time while the battery is being charged, or while clearing unnecessary log files from the unit. icListen AF User Guide © December, 2017... -
Page 29: Long Term Storage
If your icListen will be internally logging, make sure that the file system is ready (see File System Care). 9.7 Long Term Deployment For long term deployments, contact Ocean Sonics for support. icListen AF User Guide © December, 2017... -
Page 30: Troubleshooting Iclisten
If network usage on the instrument is heavy (can be caused by streaming/scanning data in Lucy, or activity on the web interface, FTP or SSH port), small amounts of data loss may occur. Reducing the network usage when possible during internal logging operations is advised to avoid this. icListen AF User Guide © December, 2017... -

If your icListen and computer are on separate private networks, it will not be possible to connect to it. Ocean Sonics’ Marco or Lucy (v4.0 or newer) can be used to reconfigure the device’s network settings to make the instrument accessible. -
