REDAS - REMOTE DATA ACQUISITION SOFTWARE

REDAS-5 software through a simplified and friendly operator interface allows to take full control of the OCEAN SEVEN 3xx probes easing real time acquisition, configuration of unattended acquisition cycles and uploading of data stored in the OCEAN SEVEN probes memory. REDAS-5 program is a true 32bit Windows application which runs flawlessly on Windows 2K, XP, VISTA and Windows 7. REDAS-5 shows graphically and numerically the acquired data allowing the operator to dynamically change the graphical and numerical setup during data acquisition. Post-processing functions and data extraction procedures in function of time, pressure or numerical intervals can be applied to acquired data in real time or on data retrieved from the probe memory. Among the operations that REDAS can perform is worth to mention: automatic start and stop of data acquisition; management of the bottle sampling (Rosette); Processing and filtering of acquired data in real time; Acquisition of geographical coordinates from a GPS device; Acquired data conversion in text files; automatic scaling of the graphical window X and Y axis.
The REDAS-5 Windows program interfaces the OCEAN SEVEN CTD probes model: • OCEAN SEVEN 316 • OCAEN SEVEN 319 • OCEAN SEVEN 320 • OCEAN SEVEN 303 • OCEAN SEVEN 304 • OCEAN SEVEN 305 • OCEAN SEVEN 316Plus • OCEAN SEVEN 320Plus • OCEAN SEVEN 304Plus
This new program is intended to replace the present REDAS Version 3 used up to now to manage real time acquisitions and stored data uploading from the OCEAN SEVEN probes. Even if it maintains the same name, REDAS-5 has been developed from the scratch using up-to-date tools and Object Oriented Programming technology.
>	REDAS-5 it is easy to use thanks to a friendly user interface based on floating multiple windows and a main menu and tool bar. A big effort was made to simplify at the most the procedure to start an acquisition, as they are usually carried in unfavorable environments and under pressure.
>	REDAS-5 gives to the operator an immediate graphical and numerical representation of the acquired data, through few keystroke or mouse click.
>	REDAS-5 manages automatically the beginning and end of an acquisition, freeing the operator that thus, can manage and attend at the probe deployment without the need to trigger the acquisition program at the same time.
>	REDAS-5 it is a true 32bit Windows® multi-treaded software allowing during acquisition the modification of the plot window as well as the parameters shown in the other open windows. Printout of plot, bottle list and value windows contents are obtainable in real time during data acquisition. Furthermore other Windows® applications can run concurrently with REDAS-5 without degrading its performances.
>	REDAS-5 take care of the safety of probe during the profile operations through different kind of alarms like: checking of probe depth, probe altitude or other error conditions, that can be customized by the operator. Alarm condition is reported to the operator though visual and acoustic signals.
Accordingly with IDRONAUT policy and in respect to the ethic of scientific research, no modification on the acquired raw data are done without the permission of the operator that can easily select the processing function among different data filtering, time lag compensations, or other specific sensor compensation algorithms. Therefore it is possible for the operator to extract from the probe stream data it needs applying the selected and customized processing algorithm. Real time extraction is primary implemented to accelerate the display of the acquired values, where only few data are shown on the screen accordingly with the chosen algorithms. Anyhow all data sent by the probe (up to 20Hz) is carefully stored in a so called “RAW” data file. Additional parameters like the GPS geographical coordinates (Latitude, Longitude), the ship bathymetry can be processed and displayed as they are probes sensors. Thanks to the modularity and the OOP technique adopted to develop REDAS-5, new sensors, additional parameters and/or post-processing algorithms can be easily added upon customer request. Nearby the real time features, the remote menu allows the operator to setup the OCEAN SEVEN probes for unattended cast and afterward to retrieve data stored in the probe internal memory, showing it with the same functions and facilities available for data acquired in real time. The compatibility with the previous version of program issue has been resolved allowing importing and processing of data files acquired with the present REDAS 3.
REDAS 5.0 distinctive characteristics:
>	Multiple floating windows
		Apart of the Main window, all the opened child windows which floats on the Windows® desktop can be resized or hidden. The position and size of each child windows are restored when the software runs again. Each child window has it own context menu allowing the operator to modify the configuration and to access the contextual help.
			The Main window is always visible at the top of the screen. Through the View menu it is possible to show or hide the opened child windows. The status part of the main window is used to indicate information about the cast currently shown, the rosette status and the probe undertaken operations.

			The Header window shows cast info like date and time, position, depth, probe info, and other useful information. They can be modified in real time without disturbing data acquisitions process.

			The Bottle window shows the list of bottles taken. The selected bottle is shown on the plot window by means of a dedicated cursor.
			The Value window numerically shows acquired data. When a cast is displayed the selected data can be linked with a cursor which appears on the plot window and vice versa. Two different methods allow the operator to show acquired data numerically: scrolling or steady.

			The Plot window quickly shows up to 8 plot lines at the same time. Each plot line can be fully customized and associated to a parameter or sensor. Scales for each plot line can be customized or managed through built-in auto-scale function. Auto-scale function can be associated to the “Y” scale too.


REDAS 5.0 distinctive characteristics:
>	Operator interface
		The Tool bar gives an easy access to the most important and used program functions.
		A dedicated database allows the operator to access cast information about: how, when and where data has been acquired.
		Deep cast is displayed in a very short time because only an extracted set of the acquired data are shown in real time.
		Separated acquisition thread running concurrently allows a painless access to the open windows functions even during real time acquisition.
		Graphical facilities are always available during real time acquisition, the shown graph and bottle list can be printed any time.
		The extraction function allows the operator to customize the strategy used to extract data from the probe stream easing the numerical, graphical display. Extraction can be selected among: pressure, time or number of acquisition..
		The post processing of acquired data can be done in real time during acquisition, thus there is no need to process again the cruise data. Post processing functions can be fully customized by the customer and they comprise: Time lag compensation, Conductivity thermal mass effect compensation, data filtering accordingly to different methods (Low pass filters, averaging, peak suppression, etc.).
		The acquired raw file is not modified, therefore the operator can always re-process it again using different settings and post-processing algorithms.
		Different formats are available to customize the representation of time, date and geographical coordinates (latitude, longitude).
>	Real time Acquisition
		Acquisition is started by a single click on the RECORD tool-bar button. Acquired data storage starts automatically without the help of the operator according to the chosen strategy: immersion of probe in water; pre-defined time.
		During the real time operations different files are automatically created by the program for each new acquisition and frequently updated. The program takes care to store the probe configuration like: sensor calibration coefficients; parameter settings; rosette type; etc. and associating them to each acquisition. This method ensures that the probe configuration information is always up to date and correctly associated with the acquired data.
		All data received from the probe is stored into the raw file. For safety and ethically purposes it cannot be edited or modified. The file is updated each 10 seconds ensuring that in case of problem with the personal computer running the REDAS-5 program, only the last 10 second of data is lost at maximum.
		Rosette management is completely automatic: the rosette type is obtained from the probe; and automatic bottle firing strategy can be defined. Anyhow the operator can decide to overpass the automatic functions performing the bottle firing manually.
		All child opened windows are regularly updated to reflect the values sent in real time by the probe.
>	Data Conversion
		Curves, data, cruise and cast information and bottle list can be exported to text files or printer using configurable format.
Personal computer minimum configuration Due to the intensive and time consuming processing performed by REDAS-5 to follow in real time the data stream coming from the probe, and considering the amount of memory needed to keep readily on line acquired data to be shown or printed, the personal computer on which REDAS-5 should run must have at the minimum the following characteristics:
		Processor HDD Memory Interfaces Screen/Graphic card Backup	PENTIUM 4 or equivalent, clock 2 GHz or better > 20 GByte > 512 MByte Mouse, Serial interface or USB interface with RS232C adapter color, 17” or bigger, 1280x1280 pixel CD-ROM R/W
