Configuring the CS90 for data recording
The Record function allows you to record echo data. The data are saved on the Processor Unit hard disk - or on an external data storage device - according to the preferences you have defined. The files can later be copied or moved to other recordable media.
Prerequisites
If you wish to save your recorded data on an external hard disk, make sure that it is connected to the Processor Unit.
Context
The File Setup parameters control how and where the recorded files are saved on the Processor Unit hard disk, or on an external disk. By adding a file name prefix, you can also identify files recorded from any specific mission or survey. You can also define a maximum size of the data files.
On the CS90, you can start and stop data recording in several ways.

a On the Operation menu, select the red circle in the Record button to start recording.
b Select the black rectangle to stop recording.
c Select the middle of the Record button to open it, and select On or Off.
The Record indicator on the top bar will switch to red colour when recording is active. The Record indicator can not be used to start or stop recording.
Procedure
1 Open the Operation menu.
2 Locate the Record button.
3 Select the middle of the Record button to see the available options.
4 Select File Setup to open the dialog box.

5 On the Directory page, select Browse to choose a folder for the data files.
Data files will normally become very large. If you wish to record large amounts of CS90 data, make sure that you have enough space on your hard disk. The CS90 is not provided with unlimited disk capacity. We recommend that you either save the data files to an external storage device, or use a network disk.
6 On the Raw Data page, type a prefix into the File name prefix text field.
If you do not have a computer keyboard connected to your CS90 system, select the Keyboard button to open an on-screen keyboard.
7 On the Raw Data page, define a maximum size for the data files.
Tip
Set the value to 0 (zero) if you do not wish to limit the file size. The Split File function will start a new file with the next ping regardless of the maximum file size you have defined.
8 On the Raw Data page, observe the Current file size field.
The current size of the file you are recording is shown in this field. Data is only shown while recording is taking place. If the current file size gets too big during recording, use the File Setup function on the Record button. This will close the current file, and then automatically continue recording to a new file.
9 Select OK to save the selected settings and close the dialog box.
