If the instrument saves files with serial names such as Cast1 Cast2 etc then you will also be prompted for a base file name for the downloaded files The cast number will be appended to this base name to create a unigue name for each cast you download You may also simply drag the selected files from the RadSoft Explorer into a Microsoft Windows folder or onto the Windows Desktop Depending on the guantity of data and baud rate downloading may take some time Status messages and a graphical indicator will show the download progress 5 4 2 Selecting Files Depending on the type of instrument and the number of data sets stored loading the directory may take a number of seconds The Device Explorer window goes blank when it is in the process of loading You can select arbitrary groups of data sets for downloading To select a contiguous group of casts click on the first item in the group then shift click on the last item or hold down the shift key while using the arrow keys To select or unselect non contiguous casts control click on them or hold down the control key while using the arrow keys to move through the directory and press the space bar to select or unselect casts 22 9 5 SETTING INSTRUMENT DATE AND TIME To set the real time clock in a connected instrument select Set Date Time from the Instrument specific menu The Set Serial Date amp Time dialog will appear Fa set hr990501 Date amp Time P
