SAA CR Logger Integration Guide Preface In many cases it is not convenient or desirable to collect data directly from an SAA using SAARecorder. In these cases, SAA data can be collected using Campbell Scientific’s CR800 or CR1000 data loggers. This user guide presents information needed to correctly set up a Campbell Scientific logger and SAAs for data collection. In this guide, for simplicity’s sake, only CR1000 is mentioned in most cases.
SAA CR Logger Integration Guide 1. Introduction ShapeAccelArrays (SAA) can be configured for use with a CR800 or CR1000. This is accomplished using a Measurand “SAA232” (or “SAA232-5”) device and “SAACR1000 Integration Suite” software.
SAA CR Logger Integration Guide Figure 2.2: Wiring diagram for CR1000 with SAA232. An example setup using a CR1000, 2 SAA232s, and an Airlink Raven XT modem is illustrated in Figure 2.4. If the back panel assembly and wiring has been done by Measurand, you will only need to connect the SAA wires to the SAA232 or SAA232-5 channel. This should be done prior to connecting the power to the logger (i.e.

Checking SAA Performance Prior to Installation Prior to installing the SAA, it is desirable to check the performance of the SAA to verify that no damage was incurred during shipping. This is done by using the Advanced Diagnostics applications in SAARecorder software.
SAA CR Logger Integration Guide the SAA232 device to your laptop by means of a “SAA232-USB” Connector (Figure 3.1). The SAA232-USB 4-pin green connector plugs into the top receptacle on the SAA232. Power is supplied to the SAA232 by connecting the red (12V) and black (Ground) wires to available ports on the CR1000 (Figure 2.2). The USB connector is then plugged into an available USB port on a computer running SAARecorder.

SAA CR Logger Integration Guide 4. Using LoggerNet Setup of the CR1000 to collect SAA data requires a basic understanding of Campbell Scientific’s LoggerNet software. For more information on Campbell Scientifics’s LoggerNet software, visit the Campbell Scientific website to obtain the user manual (http://www.campbellsci.ca/). The LoggerNet toolbar is shown in Figure 4.1.
SAA CR Logger Integration Guide Figure 5.1: SAACR_FileGen utility. Reading Interval: The frequency at which SAA observations are made within the program (also known as ‘scan interval’). An SAAF can perform measurements at 400Hz (see above), thus taking an average of 1000 samples (typical value) in less than 10 seconds. However, sufficient time must be included to account for other commands and functions within the CR1000. The number of SAAFs connected to a CR1000 also affects the collection time.

SAA CR Logger Integration Guide 6. Compiling SAA Program Files Once the main program has been successfully generated, it can be viewed using the LoggerNet ‘CRBasic Editor’. At this time, it is also possible to add other code for instruments or powering the SW12V port on the logger. Once the code has been added, it should be compiled to make sure that there are no errors. To successfully compile the new program, the SAA_Include file generated with the program is also required.
SAA CR Logger Integration Guide Figure 7.1 Selecting File Control in the LoggerNet Connect utility. Once the File Control window opens, the ‘Send’ option is used to place the SAA_Include file on the CR1000, as illustrated in Figure 7.2. The ‘Run Now’ and ‘Run On Power-up’ options should be deselected when prompted (Figure 7.3) (since the SAA_Include file will not run as a standalone application). Note: The SAA_Include file must be placed on the CR1000 before the main program will run.
SAA CR Logger Integration Guide Figure 7.2: Selecting 'Send' option in ‘File Control’. Figure 7.3: Selecting ‘Run Options’ when sending files to CR1000 logger.
SAA CR Logger Integration Guide Figure 7.4: Sending a program to the CR1000. 8. Data File Management It is critical that the data files generated by the CR1000 are effectively managed. The output folders for CR1000 data files are specified under the ‘Data Files’ tab in the LoggerNet ‘Setup’ utility (Figure 8.1). By default, the data is stored in the C:\CampbellSci\LoggerNet directory and given a name of “DataloggerName_TableName_#.dat”.
SAA CR Logger Integration Guide Figure 8.1: Specifying the destination of data files using the LoggerNet Setup utility Note: Before a new project begins, any CR1000 data files residing in the output file directory should be removed. Otherwise, data from the new project may get concatenated to the existing data file, causing abnormalities in the results. 9. Manual Data Collection For each setup, the PROJECT_INFO, SAAx_DATA and SERIAL_ERRORS data files must be recorded.
SAA CR Logger Integration Guide Note: If your PC is using Daylight Savings Time, take care NOT to disrupt the time setting currently employed by the CR1000. If the station clock is adjusted to match Daylight Savings Time on your PC, gaps or overwrites in the data file will occur. If you need to adjust the station clock, make sure you set your PC clock to Standard Time. Figure 9.1: Disabling scheduled data collection.
SAA CR Logger Integration Guide Figure 9.2: Collecting data using the LoggerNet ‘Connect’ utility. 10. Automated Data Collection Once the manual data collection process has been tested, the data collection process can be automated by specifying the desired data collection interval in the ‘Schedule’ tab of the LoggerNet ‘Setup’ utility (Figure 10.1). Check the ‘Scheduled Collection Enabled’ checkbox.
SAA CR Logger Integration Guide Figure 10.1: Enabling scheduled data collection. 11. Manual Conversions of SAA Data SAA data collected using the CR1000 can be manually converted to a format viewable in the Measurand SAA3D or SAAView viewer software using the Measurand SAACR_raw2data utility. Detailed instructions are found in the SAACR_raw2data instruction manual (located in the installation directory). Before data can be converted, calibration files for your SAAs must reside on your PC.
SAA CR Logger Integration Guide Once the conversion is completed, you will be prompted on whether or not you want to view the data using either SAA3D or SAAView. 12. Viewing SAA Data When proceeding to view SAA data directly after a SAACR_raw2data conversion, you will be prompted to select which SAA viewer you would like to use. In most cases, you can use either SAAView or SAA3D. However, if you are converting convergence data, you can only view the data in SAAView.

Automated Data Conversions Once at least one successful manual conversion has been completed, SAA data can be automatically converted to a format viewable in SAA3D or SAAView software.
SAA CR Logger Integration Guide LoggerNet ‘Task Master’ utility. The first manual conversion is necessary to generate the pref_project.txt file which contains conversion settings for subsequent operations.
SAA CR Logger Integration Guide To configure the task, click on the ‘Configure Task’ button. Once the configure screen is open (Figure 13.2), check ‘Execute File’ and browse to C:\Measurand Inc\SAA3D\SAACR_raw2data.exe (or the appropriate folder containing this file). Under ‘Command Line Options’ you must specify the pref_project.txt file that was generated when the first manual conversion was completed. It should be located in the same directory as the raw data.
SAA CR Logger Integration Guide Note: Any of the files required by SAACR_raw2data (E.g., calibration files, multi_saa_allcart.txt) cannot be open while the process is running. Otherwise an error will be generated. Figure 13.3: Viewing the status of scheduled tasks in Task Master. 14.Saving Data in Overwrite File Mode If data is to be collected over long time periods, eventually the SAA data files will become very large and require an increasing amount of time to process.
SAA CR Logger Integration Guide file (text file of all Cartesian coordinate records) will no longer be updated in this mode, just the multi_saa_curcart.txt (text file of most recent Cartesian coordinate records). Figure 14.1: Switching the "Data File Output" option in the LoggerNet 'Setup' utility to 'Overwrite Existing File'. If the SAA Data file is viewed when ‘Overwrite File’ is implemented, only the most recent data records will be contained in the file.
