Welcome to EASYEST LX !                                            -
                                                                   -
        EASYEST LX is an icon-driven data acquisition, analysis,   -
        and graphics program. EASYEST LX can be used interactively -
        for quick troubleshooting and system prototyping. It also  -
        offers record and playback capabilities that allow you to  -
        create and replay automated sequences of operations.       -
                                                                   -
   THE EASYEST LX DEMO SYSTEM                                      -
                                                                   -
        The demo system is a subset of the complete EASYEST LX     -
        system.                                                    -
                                                                   -
        Certain features have been limited. An example is data set -
        size, which is 128 points in the demo vs. 4096 points (more-
        for acquisition to disk) in the full system.               -
                                                                   -
        All functions having to do with file I/O or printing have  -
        been disabled, including scroll from disk. PID control,    -
        Plotter Output, PCX Output, Transducer Calibration, and    -
        A/D to Disk have also been disabled.  It is still possible -
        to access the dialog boxes for these functions.            -
                                                                   -
        Acquisition is simulated by a software routine called the  -
        DASDEMO, which acts just like an acquisition board. DASDEMO-
        allows you to simulate acquiring data from up to 4         -
        channels, starting with channel 0. Channel 0 contains a    -
        sine wave, channel 1 a noisy sine wave, channel 2 a        -
        sawtooth wave, and channel 3 an EKG wave. DASDEMO also     -
        allows you to simulate digital I/O.  EASYEST LX acquires   -
        data at maximum hardware speeds for all supported          -
        boards.                                                    -
                                                                   -
   EASYEST LX ENVIRONMENT OVERVIEW                                 -
                                                                   -
        EASYEST LX's screen displays a menu along the top of the   -
        screen with icons along the other three sides. The large   -
        center portion of the screen is for data display. Menu     -
        items, icons, and dialog boxes are used to communicate with-
        the EASYEST LX program.                                    -
                                                                   -

        The seven items on the menu at the top of the screen       -
        provide a convenient way to perform system operations and  -
        to set system parameters. Press the LEFT mouse button on a -
        menu item to select that menu item. To display on-screen   -
        help for a menu item, select the item with the RIGHT mouse -
        button.                                                    -
                                                                   -
   ICONS                                                           -
                                                                   -
        Icons are used to initiate EASYEST LX's data acquisition,  -
        analysis, graphics, and output functions. Most output      -
        functions, including plotter, printer, data file, and PCX  -
        file output have been disabled in the Demo System. A short -
        description of each outer border icon is displayed in the  -
        bottom right corner of the screen when the mouse pointer   -
        is positioned on that icon. An icon is selected by pressing-
        the LEFT mouse button when the pointer is positioned on the-
        icon. Selecting an icon initiates that icon's function.    -
        To display on-screen help for an icon, point to that icon  -
        and press the RIGHT mouse button                           -
                                                                   -
   MEMORY LOCATIONS                                                -
                                                                   -
        EASYEST LX stores data in memory locations and permits     -
        access to data via memory icons. The memory icons are      -
        located to the left of the large center portion of the     -
        screen and are labeled 0 - 15. Data acquired using the A/D -
        icon is stored in the memory location corresponding to its -
        channel number. For example , data acquired from channel 3 -
        is stored in memory location 3. Another memory location    -
        labeled T for Temporary is used to store results of        -
        analysis and interactive graphics operations. Memory       -
        manipulation icons SAVE, To T, SUB, etc. allow you to move -
        data from one memory location to another.                  -
                                                                   -
        Note: Each memory location has a 'Y' and an 'X' data pair. -
              When data is acquired, the collected 'Y' data is     -
              stored in a memory location along with the 'X' TIME  -
              information.                                         -
                                                                   -
        You can make a memory current by pointing to the memory    -
        icon with the mouse and clicking the LEFT mouse button. A  -
        yellow border will then be displayed around the icon. The  -
        SAVE icon copies the contents of the T memory to the       -
        currently selected memory. The To T icon copies the        -
        contents of the current memory to the Temporary memory. The-
        SUB icon extracts a sub-section of the array in the current-
        memory location and stores the result in the T memory      -
        location.                                                  -
                                                                   -
        Any operation to be performed on data, such as calculating -
        a derivative or plotting data, is performed on the current -
        memory location.                                           -
                                                                   -
                                                                   -
                                                                   -
   DIALOG BOXES                                                    -
                                                                   -
        Dialog boxes with input fields appear on the screen when   -
        the system needs to display information or when the system -
        requires additional information.                           -
                                                                   -
        Blue text in a dialog box is reporting information and     -
        cannot be changed. Yellow text lists parameters such as    -
        acquisition rate which can be changed. Yellow text is also -
        used to initiate actions, such as 'OK' to exit a dialog box-
        and execute its functions. (Colors are for EGA/VGA color   -
        monitor with default color settings.)                      -
                                                                   -
        The value of an input box can be changed in two ways. Some -
        input boxes allow keyboard input and others require that   -
        you click on the input to step through possible choices.   -
        Most dialog boxes contain OK and Cancel buttons. Selecting -
        OK (or pressing ENTER) accepts the values that appear in   -
        the input fields, closes the dialog box, and executes the  -
        operation. Selecting Cancel (or pressing ESC) restores the -
        input field values to their previous values and closes the -
        dialog box without executing any operation.                -
                                                                   -
        Most icon dialog boxes contain an input field located in   -
        the bottom right corner of the box. This selection can be  -
        toggled between On and Off, selecting whether the dialog   -
        box is to be displayed during the playback of a recorded   -
        sequence. When not recording a sequence, this selection is -
        ignored.                                                   -
                                                                   -

   MENU ITEM - Devices                                             -
                                                                   -
        Use the Devices menu item to specify the voltage range and -
        scaling algorithm used in converting to engineering units  -
        for each A/D channel. A different voltage range and scaling-
        algorithm can be used with each channel. Note that the DAS--
        DEMO driver scales all channels to the voltage range set   -
        for the first channel. Therefore, in EASYDEMO, each channel-
        will be scaled similarly. The EASYEST LX demo system has   -
        the thermocouple scaling disabled. EASYEST LX only works   -
        with a demonstration driver called DASDEMO. The DASDEMO    -
        driver emulates a 4 channel data acquisition board.        -
                                                                   -
        A transducer calibration routine is also available under   -
        the Devices menu option. This routine can be used to       -
        generate the polynomial coefficients which are used to     -
        compute the physical units measured by the transducer from -
        the voltage acquired from the DAS board's A/D channel.     -
                                                                   -

        The Printer menu item displays a list of over 300 supported-
        printers. The user can select the printer type as well as  -
        the DOS device to receive all printer information. Valid   -
        DOS devices include LPT1, LPT2, COM1, COM2, valid DOS      -
        filenames, and any other DOS device. Printer output has    -
        been disabled in the demo system.                          -
                                                                   -

        EASYEST LX supports plotters that understand HPGL          -
        (Hewlett Packard Graphics Language). Plotter output can be -
        directed to COM1 or COM2. Plotter output can also be       -
        directed to a file through the HPGL icon. Plotter output   -
        has been disabled in the demo system.                      -
                                                                   -

        The Board menu item displays the software configuration of -
        your current data acquisition board as specified by the    -
        external DAS driver. The EASYEST LX demo system allows     -
        only the DASDEMO board driver to be used.                  -
                                                                   -

        Use the Style menu item to specify parameters that affect  -
        the appearance of graphs. When recording sequences, keep   -
        in mind that all current styles are saved with the graphics-
        commands. This feature allows you to switch styles inside  -
        a sequence.                                                -
                                                                   -

        Use the Edit menu item to edit ASCII files (including      -
        sequence files). The editor can be used while recording a  -
        sequence to remove unwanted commands; however, the edit    -
        option is not recorded in the sequence. The Edit feature   -
        has been disabled in the EASYEST LX demo system.           -
                                                                   -

        Use the Quit menu item to exit to DOS. When EASYEST LX is  -
        exited, all options in the Devices, Printer, Plotter, and  -
        Style menus are saved in a configuration file. Next time   -
        you use EASYEST LX, this file is used to set up the system -
        as it had been when you last exited it.                    -
                                                                   -

        The Axis Type icons are located to the lower right of the  -
        large center portion of the screen. The seven axis types   -
        draw the axes depicted on the icons. The last three axis   -
        types allow for two vertical axes with different label     -
        ranges. To specify a second Y axis range, plot a data set  -
        using one of the last three axis type icons. Select the    -
        Plot Axes icon to open the axis plot parameters dialog box -
        and change the Vertical Axis minimum and maximum values to -
        set the new range. Then overlay a data set using the       -
        overlay data plot icon. The new data is plotted using the  -
        new Y range.                                               -

        The six data acquisition icons are located in the upper    -
        left side of the EASYEST LX screen. The data acquisition   -
        icons perform A/D, D/A, digital I/O, strip chart           -
        recording, PID loop control, and high speed A/D to disk.   -
                                                                   -

                                                                   -
        Select this icon to acquire from 1 to 4096 data points per -
        channel into memory locations 0 through 15. All 16 channels-
        can be sampled, with up to 16k points of data acquired in  -
        one burst. When reading from multiple channels, all        -
        channels must sample the same number of points. For example-
        you can acquire 1k points on 16 channels or 4k points on 4 -
        channels. Data from channel 0 is automatically stored in   -
        memory location 0, channel 1 in memory location 1, etc.    -
        The EASYEST LX demo system only allows 128 data points per -
        channel.                                                   -
                                                                   -
        The A/D icon can collect at the maximum rate of the data   -
        acquisition board being used. EASYEST LX supports DMA,     -
        external clocking, and external triggering for data        -
        acquisition boards that have the hardware capability.      -

                                                                   -
        Select this icon to acquire and display up to eight        -
        channels of data starting at any of up to 16 channels on   -
        your data acquisition board. Data may also be directed to a-
        disk file (option not available in the demo system). If the-
        strip chart time duration is set to zero, the strip chart  -
        will run until a key is pressed or left mouse button is    -
        clicked.                                                   -
                                                                   -
   PID Icon                                                        -
                                                                   -
        Select this icon to perform either single point PID        -
        (Proportional Integral Derivative) control or PID tuning.  -
        PID can be used to aid in the control of a dynamic system  -
        by outputting a signal that is related to the difference   -
        between the desired and the actual values. PID control is  -
        disabled in the EASYEST LX demo system.                    -
                                                                   -
        The single point PID allows you to perform up to 16 PID    -
        loop calculations at one time. The number of D/A channels  -
        available on your hardware determines how many PID loops   -
        can be running, with a maximum of 16. Using the single     -
        point PID allows you to perform other EASYEST LX           -
        operations while the PID control is running.               -
                                                                   -
        The PID tuner will allow you to run one PID loop. You      -
        can alter the P, I, and D parameters as well as the        -
        setpoint while the PID calculations are taking place.      -
        The tuner also displays a strip chart of the setpoint      -
        value and the signal that is being controlled by the       -
        PID calculation.                                           -
                                                                   -
   A/D to File Icon                                                -
                                                                   -
        Select this icon to acquire data to a binary data file.    -
        The data is converted to an EASYEST format when read back  -
        via the Scroll from Disk Icon or File I/O Icon. EASYEST    -
        LX can collect and store data from up to 16 channels into  -
        data files as large as 32 Mbytes. Each data point requires -
        4 bytes. Your data acquisition board must have DMA         -
        capabilities in order to use the A/D to File Icon. The     -
        EASYEST LX Demo System has the A/D to File Icon disabled.  -
                                                                   -
ANALYSIS ICONS                                                     -
                                                                   -
        EASYEST LX allows you to perform analysis on your data     -
        interactively or in an automated sequence. The following   -
        analysis icons are available in EASYEST LX.                -
                                                                   -
   FFT Icon                                                        -
                                                                   -
        Selecting this icon performs either a forward or inverse   -
        Fast Fourier Transform. The forward FFT decomposes a signal-
        into its periodic component waves of various frequency and -
        amplitude. The inverse FFT combines the component          -
        frequencies into a signal.                                 -
                                                                   -
        If a forward transform is selected the FFT is performed    -
        on the currently selected memory location and the result   -
        is returned to the T memory location. If inverse transform -
        is selected, the amplitude must be in the currently        -
        selected memory location and the phase information must    -
        be in the T memory location. The IFFT result is placed in  -
        the T memory location.                                     -
                                                                   -
   Peak Icon                                                       -
                                                                   -
        Select this icon to find local maxima or minima in the     -
        data, using a least square quadratic fit method. The       -
        algorithm uses a quadratic fit in the search for peaks     -
        (or valleys) to differentiate between noisy spikes and     -
        actual, parabolic-shaped peaks (or valleys).               -
                                                                   -
        For the algorithm to detect true peaks or valleys rather   -
        than local fluctuations due to noise, the user must enter  -
        the approximate number of points that define a peak or     -
        valley.                                                    -
                                                                   -
   Digital Filters Icon                                            -
                                                                   -
        Select this icon to perform a filter operation in the time -
        domain. This filter is useful for removing unwanted signal -
        frequency components. For example, a low pass filter is    -
        useful for removing high frequency noise, and a high pass  -
        filter is useful for removing low frequency baseline drift.-
        The filter is created by EASYEST LX by multiplying an ideal-
        filter impulse response by a Blackman window.              -
                                                                   -
        The available filter types are low pass, high pass, or     -
        band pass. You must specify the filter type, the cutoff    -
        frequency (for band pass, the upper and lower cutoff       -
        frequencies), and the transition width (the region where   -
        the filter response drops off).                            -
                                                                   -

        Select this icon to perform up to nine statistical analyses-
        on data in the current memory location. The results of the -
        analyses are placed in the T memory location and can also  -
        be displayed in one of the graph area quadrants. You can   -
        select the desired operations to be performed from the     -
        following list:                                            -

        otherwise, a message is returned stating invalid memories  -
        have been specified. If the memory locations used contain  -
        a small number of points (less than 15), the resulting plot-
        may be drawn off the edge of the plotting area. Waterfall  -
        plots are useful for comparing different runs on the same  -
        channel or data acquired on multiple channels during a     -
        single acquisition.                                        -

        Select this icon to call a recorded sequence from within   -
        another sequence. The called sequence is executed as part  -
        of the current sequence during playback. This feature is   -
        accessible only when record is on.                         -

        Select this icon to add a Yes/No command to the sequence   -
        file. When this command is encountered, the sequence       -
        execution is paused until [Y] or [N] is input from the     -
        keyboard. If [Y] is pressed, the subsequent sequence       -
        command is executed; if [N] is pressed, the next sequence  -
        command is ignored. Because no message command is used to  -
        indicate that the sequence is waiting for input, you may   -
        want to add a Message command before the Yes/No command    -
        in your sequence so that a message is printed to the       -
        screen before the sequence is paused. This feature is      -
        accessible only when record is on.                         -

        EASYEST LX tools are utilities that do not generate or     -
        modify sequence commands and are therefore not saved in    -
        sequences; thus if a tool is selected while recording a    -
        sequence, the tool is not used when the sequence is played -
        back and it does not appear anywhere in the sequence file. -
        EASYEST LX tools include the color palette, help, waveform -
        generator, function key programming, and the record icons  -
        View and Flow.                                             -
