Defining the file and folder settings for data recording
A useful function of the ST90 is it ability to record echo data. You can save the data to the Processor Unit hard disk, or onto an external storage device. To retrieve the data files you need to know where they are, and which file names that have been used. The data files can be played back on the ST90. The data files can later be deleted, copied or moved to another storage device. You can keep the recorded files for future reference, or for training purposes.
Context
Before you start recording, make sure that you have defined where you wish to store the data files. If you wish to save your recorded data on an external hard disk, make sure that it is connected to the Processor Unit.
Tip
Unless you really need to record data for playback and/or training purposes, you should use this function with care. The data files will fill you hard disk very fast!
File Setup controls how and where the recorded files are saved on the Processor Unit hard disk, or on an external storage device. By adding a prefix to the file names you can identify the files you have recorded during a specific mission or survey. You can also define a maximum size of the files.
Note
The data files will normally become very large. If you wish to record large amounts of ST90 data, make sure that you have enough space on your hard disk. The ST90 is not provided with unlimited disk capacity. We recommend that you save the data files to an external storage device.
If the current file size gets too big during recording, select Split File on the Record button. This will close the current file, and then automatically continue recording to a new file.
