Intro

The BATLOGGER RS X is used to record bat calls with up to 8 microphones. With a real-time recording system, the ultrasonic signal is digitized directly without modification and at a high sampling rate. With the BATLOGGER RS X, the signal is continuously analysed and only stored if bat activity is detected. The read data is stored in an internal RAM memory and in a second step, based on various criteria, individual recordings (sequences) are written to the hard disk as a file. In addition to the bat calls, which are saved as a so-called WAVE file, other data such as time, date, place of recording, temperature are saved in text format as an associated .xml file. In order to have an overview of the use of the BATLOGGER RS X, its operating status is continuously written to a “LOG” file.

Data storage

The individual acoustic recordings are written to the hard disk as.wav files. For each.wav file a.xml file is stored, which contains the set parameters, as well as date, time, position and temperature at the time of recording. The ultrasonic data of the microphone are first written to the internal “Random Access Memory” (RAM) of the BATLOGGER RS X. The individual recording sequences are then automatically transferred from the RAM memory to the hard disk after each recording.

External storage media

External hard drives, USB sticks or SD cards can be used as transport media. Hard disks and USB sticks have higher priority when copying than SD cards. If both a hard disk and an SD card are available for copying, the hard disk is used. If there are several hard disks, the first hard disk/stick found is used.

The media must be formatted with FAT32 or EXT4. NTFS is currently not supported. This is no problem for USB sticks and SD cards. However, a large hard disk cannot be formatted with Windows FAT32 onboard tools. It requires freely available tools which can be found on the Internet.

The external media can be plugged in or removed at any time, unless a copy operation is in progress (green LED flashes). No explicit “ejection” is necessary. The system does this automatically as soon as a copy operation is completed on the external device.
