BATLOGGER A/A+ Manual © 2017 Elekon AG 7/44
2.3 General
The BATLOGGER A/A+ is a data logger, which records ultrasound vocalisations of bats in realtime, and stores them for later processing on a micro SD / SDHC memory card (real-time recording system).
In a real-time recording system, the ultrasonic signal is digitized directly without change and with high sampling rate. Hereby the BATLOGGER A/A+ continuously analyses the signal and only stores it to the SD card when bat activity is detected. The signal is recorded to internal
RAM and subsequently, if certain criteria is fulfilled, stored as recording files (sequences of echolocation calls) onto SD card.
Apart from the bat calls, which are stored as standard audio WAVE files, additional information is written in text format into a “.xml” file, which stores all the settings of the BATLOGGER A/A+ at the time of recording, including time, date and location of the recording, and the current temperature.
To allow a later overview over all deployments of the device, its operating state is being written to a “LOG” file on the SD card.
The BATLOGGER A/A+ is thus especially suitable for autonomous operation and unattended monitoring. The BATLOGGER A/A+ is primarily used stationary, which is often referred to as passive monitoring.
The only difference between BATLOGGER A and BATLOGGER A+ is the battery type (size) and the corresponding operation time.
2.4 Device revisions
This device underlays continuous development efforts to maintain and improve its producibility and functionality.
Hardware revision history:
HW Revision B3: Initial release
HW Revision B4: Minimized power consumption during sleep mode
The revision number can be found in the BATREC.log file in the “power on” entry.
BATLOGGER A/A+ Manual © 2017 Elekon AG 8/44
2.5 Data storage
The audio files are stored on the micro SD memory card as #****.wav files (where # = 4 digit serial number of the device), with consecutive numbering (****). For every #****.wav file, a
#****.xml file is stored, which contains all parameter settings, date, time, geographic position and temperature at the time of recording of the corresponding WAVE file. Ultrasound data of the microphone are first written to the internal Random Access Memory (RAM) of the device. After termination of a single recording sequences (Recording...), the data is stored automatically from
RAM to the SD card (Saving... #****.wav). During this storage time (duration depends on file size and card type), the device is blocked.
SD card: The device uses micro SD / SDHC /SDXC cards with FAT32 file system as storage media. When the term “SD card” is used, always a micro SD / SDHC /
SDXC card is meant. Test have shown, that cards of different vendors may vary in writing and erasing speed. We refrain from giving recommendations for specific products or vendors, as offered sizes and technologies change constantly, which may also influence card performance. SD cards may have a write protect switch that prevents writing to the cards when the switch is on LOCK. Please make sure to disable the write protect switch of the SD card before using it.
SDXC cards : SD cards larger than 32 GB (SDXC cards) may be formatted with exFAT upon delivery and must be formatted by with FAT32 before use. To do this insert the SD card into the SD card slot and turn on the device. You will be asked whether the card should be formatted. Press to format and confirm with .
CAUTION: All data on the SD card will be deleted.
SD card content : A recent version of BATPARS Editor software (Windows and
Mac) is stored on the included SD card. The executable file is in directory
Software/BATPARS and can be started from there directly. Installation is not required.
A recent version of BatExplorer PC software is stored on the included SD card. It must be installed on the computer before first use. It can be found in the directory
Software/BatExplorer.

5 Record bat calls
For long term passive monitoring, the device usually only operates during the night and “sleeps” during the day to save battery power and SD card space (delayed recording).
It is also possible to immediately start record mode to test the installation or to use the device for active monitoring by executing the “Test record” function in the main menu.
5.1 Delayed recording
(Recording in time frames)
One or two operation time frames can be configured.
During the operation time (record mode), the device detects and records bat calls depending on the recording and trigger settings (see below).
During the sleep time (sleep mode), the device goes into power saving mode and turns off any peripherals. It will only wakeup if aborted by the user.
The time frames can be configured flexibly. The times can also be set dynamically by the position of the sun (sunrise and sunset). The device date/time and location must be configured correctly in order that the dynamic times are calculated accurately (see also chapter 8.2).
Example:
• Nr. Days = 2
• T1 Start = 20:30 (Sunset) T1 Stop = 01:30
• T2 Start = 04:00 T2 Stop = 07:30 (Sunrise + 15min) main

Sleeping:
15:32 – 20:15 next: Rec T1
Programmed time frames are displayed.
The device is now in sleep mode.
Press key to wakeup the device, abort delayed recording and exit to main menu.
When a time frame start time has passed, the device will wakeup and start recording mode.
When a time frame stop time has passed, the device will go back to sleep mode.
BATLOGGER A/A+ Manual © 2017 Elekon AG 22/44
5.2 Record mode
The device can be operated in different ways.
In automatic recording the signal from the microphone is constantly monitored and the recording started automatically, when a triggering event is registered (detected ultrasound signal, e.g. bat call). The duration of such recordings depends on the presence of the triggering criteria. The default setting allow for a recording duration which includes 0.5 seconds before the first and 1 second after the last trigger event (pre- and post-trigger). With the default settings, the shortest recording duration is therefore 1.5 seconds, which corresponds to roughly 1 MB of data on the SD card. To reduce recurring recordings of the same animal, a trigger ignore time can be configured.
If the device is set for continuous recording , the RAM is filled with data and thereafter data are written to the memory card. As the loggers RAM is limited to 32 MB, the length of a single recording sequence can not exceed approx. 53 seconds, but can be set to less. Subsequently this recording sequence will be written as #****.wav file to the SD card and a new recording will start, thereby overwriting data in RAM. The time required for data storage to the memory card is largely depending on the file size but also on the type of card. In general the writing of the file should require significantly less time than the recording itself.
In manual recording the triggering has to be performed through the key pad and may also be stopped this way. If a manual stop does not occur, the recording will stop automatically after a user selectable manual trigger time (default = 10 sec), and the #****.wav file be written to memory card.
In record mode, the device displays date/time, temperature, number of recordings, SD card space used and battery status. The following functions can be executed:

5.3 Trigger modes
There are different approaches to detect bat calls. As the nature is not predictable, none of them is perfect. The difficulty lies in the distinction between signal (bat calls) and unwanted noise.
Different algorithms are implemented and can be selected to automatically trigger recordings.
Depending on the recording location (e.g. noisy environment, insects, etc.) and operation purpose (e.g. passive or active monitoring, etc.), it may be good to use different trigger modes and/or trigger settings.
5.3.1 CrestAdvanced trigger
Responds to all loud, narrow noises like bat calls, sensitivity to disturbing noise minimized. Very sensitive, detects even very quiet respectively far away calls. Sensitivity and frequency bounds can be adjusted. Responds to any loud, narrow-band sound, e.g. to technical sounds and insects.
5.3.2 Crest trigger
Responds to all loud, narrow noises like bat calls, but also technical noise and insects. Very sensitive, detects even very quiet respectively far away calls. Sensitivity and lowest frequency can be adjusted. Responds to any loud, narrow-band sound, e.g. to technical sounds and insects.
5.3.3 Period trigger
The difference in sound production of bats (vocal cords) and insects (stridulation) affects the continuity period. The trigger period takes advantage of this. Insects (grasshoppers, crickets) do not trigger or only very rarely but low frequency bats may not be identified.
5.3.4 SD trigger
Similar to the period trigger, the SD trigger uses the periodicity of the signal to distinguish insects from bats and only triggers if sinusoid signals (bats) are present. To adapt to different recording environments, the sensitivity and frequency bounds can be adjusted.
5.4 Interval recording
(Record in time intervals)
As with time delayed recording, time frames have to be defined and a number of days must be set. When also a recording interval is entered, then the device switches to record mode at the start time, but only for a single recording or max. for one minute.
Then further recordings are blocked for the programmed number of minutes (”RecIntvl” / default
= 0 = off). This is followed by another record mode. This interval operation continues to the end of the time frame. For this interval operation the various trigger modes can be used.
Example:
• Rec Intervall = 3
Ready to record Recording blocked
Record mode
Time window 1
Ready to record Recording blocked ...
BATLOGGER A/A+ Manual © 2017 Elekon AG 24/44
6 Process recordings
For immediate control, stored audio files can be reviewed. Recording details such as date, time, length, peak frequency and more can be displayed.
Single recordings on the memory card can also be erased through this mode. Erasing the complete memory card must be achieved by formatting it (Settings menu).
6.1 Select folder
Depending on the settings, the recordings are stored in folders on the SD card. Per default, every night a new folder will be used:
•
•
• BL20150401
◦ 12340001.wav
◦ 12340002.wav
BL20150402

9 Recordings and Files
9.1 The audio data file ”xxxxxxxx.wav”
After completion of recording into internal RAM, the stored data is written as standard audio
WAVE file onto the inserted SD card with the file name ”xxxxxxxx.wav”. (e.g. 10160435.wav)
The first four digits identify the serial number of the device and the following four digits exhibit the consecutive number of the recorded files on the inserted SD card.
The above example therefore identifies the 435th recording on this SD card of the device with the serial number 1016.
The *.wav file contains all the uncompressed raw measurement values of the analogue to digital converter and a “header”, which is specific to the wave format. This “header” contains, amongst other information, the sampling rate of the digitiser.
Concurrent with these recorded wave data, a file containing meta information about the recording (see below) is saved to SD card with the name *.xml (in our example 10160435.xml).
The recordings can optionally be stored into sub-folders (daily, weekly, monthly). See also chapter 8.2.5.
The standard *.wav files can be read and opened with general audio software or bat specific sound analysis programs. It may be displayed as time signal or spectrogram. The latter offers best possibilities to identify species.
Elekon AG offers a specific analysis software for Windows PCs: BatExplorer . It can be found on the included SD card or can be downloaded from www.batlogger.
com .
WSL offers BatScope , a Mac software tool for management and preview of recorded data, which will eventually be extended to bat species identification: see http://www.wsl.ch/fe/biodiversitaet/produkte/batscope/ or [email protected]
BATLOGGER A/A+ Manual © 2017 Elekon AG 37/44
9.2 Meta data file ”xxxxxxxx.xml”
With every saved recording ”xxxxxxxx.wav” audio file, an additional information file
”xxxxxxxx.xml” (e.g. 10160435.xml) is saved, following the same numbering convention, and containing various meta information on recording time, date, location, temperature and device parameter settings.
Example of the content of an *.xml meta information file:

9.3 Log file "BATREC.log"
When in use, the device automatically writes a log file “BATREC.log” in text format to the
SD card. Every text line is preceded by the serial number (SN) of the device writing the log.
In the file ”BATREC.log”, all activities of the device are listed chronologically.
Events like starting up or shutting down are logged accurate to the minute, while logging of the normal recording activity only happens every hour.
Example BATREC.log:

Settings, that are changed interactively on the device are also saved to the file.
When formatting an SD card, the parameter file will be preserved.
Without the ”BATAPARS.xml” file on the SD card, the device starts with its internal ”CMOS” parameters, which correspond to the values last set.
9.5 Google-Earth file ”route.kml”
A new file is created if no “route.kml file is available one a recording is stored for backwards compatibility reasons.

10.3 Test microphone
Microphone testing: The ultrasonic microphone should be tested on a regular basis as it may become less sensitive over time, especially if it was exposed to moisture and weather. Keep it clean and dry to get best results.
10.3.1 Record silent spectrum
1. Place the white protective cover over the microphone in order to block any noise from reaching the microphone. Go in a silent environment.
2. Use the “manual test microphone“ function (see chapter 8.2.3) or start a manual recording.
3. Compare the silent spectrum to the microphones specification.
10.3.2 Record a test tone
If you have access to an ultrasonic tone generator that produces reproducible output, you can record that tone and measure the frequency peak of the tone in the recording with appropriate audio software (e.g. Audacity).
