Basic Steps for Configuring Sampling Parameters
2 Basic Steps for Configuring Sampling
Parameters
This chapter explains the basic operations you need to perform when configuring EA-200
sampling parameters from the E-Con EA-200 application. Before performing any of the
procedures in this chapter, be sure to connect the EA-200 to your ClassPad.
Configuring Parameters for Sampling with a Single Sensor
Use the [Single] tab of the Sensor Setup window to configure the parameters for a single
sensor.
• The procedure for configuring sampling settings on the [Single] tab is similar to a Windows
Setup Wizard. As you select a sensor and input setting values on the [Single] tab, settings
are adjusted automatically in order to make it possible to perform sampling properly. Even if
you are configuring settings for a single sensor, you should use the [Multiple] tab when you
want to configure all of the detailed settings yourself.
u To configure parameters for sampling with a single sensor
(1) Start up the E-Con EA-200 application.
• This displays the [Single] tab of the Sensor Setup
window.
• If the E-Con EA-200 application is already running
and another window (besides the Sensor Setup
window) is displayed, tap C to change to the Sensor
Setup window.

(3) Select the sensor you will use for sampling.
• Tap one of the tabs ([CASIO], [Vernier], [Custom]), and then tap the option button
next to the name of the sensor you want to select. For details about each of the
selectable sensors, see the “10 Sensor List”.
• Tapping the [Custom] tab displays a sheet for configuring the parameters of a userdefined custom probe. For more information, see “Using a Custom Probe” on page
3-12.
(4) After selecting a sensor, tap [Set].
• This closes the Select Sensor dialog box. The Sensor Setup window now shows the
name of the sensor you selected, along with boxes for the sample range and total
elapsed sampling time (Total Sampling Time).
• The example screen below shows what would appear if when the CASIO
Temperature (°C) sensor is selected.

Basic Steps for Configuring Sampling Parameters
• Selecting some sensors will cause different parameters from those shown above to
appear. The following table explains you should go for more information about such
these sensors.
For this type of sensor:
Go here for more details:
[CASIO] tab, [Microphone-FFT]
See “Microphone-FFT Parameters” on page 2-4
for more information.
[Vernier] tab, [Photogate]
or [Photogate (Pulley)]
See “Photogate Sensor Parameters” on page 2-5
for more information.
• The [Setup] menu is unavailable while [Speaker (Sample Data)] is selected on the
[CASIO] tab of the Select Sensor dialog box.
• When [Speaker ( y = f (x))] is selected on the [CASIO] tab of the Select Sensor dialog
box, sampling is not performed by a sensor. Instead, the sound of the waveform of a
function input on the ClassPad is output from the EA-200’s speaker. See “6
Outputting a Function to the Speaker” for more information.
(5) Tap the [Total Sampling Time] box.
• This displays the Total Sampling Time dialog box.
Tapping here displays a menu of
units (msec, seconds, minutes,
hours, days) for the total time.
Use the ClassPad
keyboard to input a
total time value.
• If you specify a total sampling time value in the range of 10 seconds to 1 day, starting
the sampling operation will automatically enter the Real-Time mode and perform realtime graphing during sampling.
(6) To apply the current settings on the Total Sampling Time dialog box, tap [Set].
• This closes the Total Sampling Time dialog box, and displays the recalculated total
sampling time in the Total Sampling Time box on the Sensor Setup window. See the
“Tip” on the next page for information about how recalculation is performed.
(7) At this point you could configure advanced setup parameters, if you want.
• See “3 Setup” for more information.
(8) You can start sampling immediately or you can save the setup in memory for later
recall.
• To start sampling immediately, tap V. For more information, see “5 Executing a
Sampling Operation”.
• To store the setup in memory, tap [SetupMem] on the menu bar, and then tap [Store].

Basic Steps for Configuring Sampling Parameters
Tip
• When you use the above procedure to configure sampling parameters for a single sensor, the
sampling mode is selected automatically in accordance with the specified total sampling time. In
this case, the parameters of the Setup dialog box’s [Sample] tab and [Trigger] tab are also
configured automatically. The current sampling mode is indicated in the status bar.
For information about the mode indication in the status bar, see “E-Con EA-200 Application
Status Bar” on page 1-7. For information about the Setup dialog box’s [Sample] tab and [Trigger]
tab, see “3 Setup”.
• Tapping [Set] on the Total Sampling Time dialog box automatically configures the sampling
interval in accordance with the total sampling time that you input on the dialog box. The number
of samples value is calculate and rounded to the nearest integer. The number of samples integer
value is used to recalculate the total sampling time ({Number of Samples} × {Sampling Interval}),
and displays the result in the Total Sampling Time box on the Sensor Setup window. All of this
means that the value you input on the Total Sampling Time dialog box may not necessarily the
value that appears on the Sensor Setup window.
k Microphone-FFT Parameters

Modes
The [Mode] box at the top of the [Sample] tab of the Setup dialog box controls the current
mode setting.
There is a selection of five modes, depending on the type of data being sampled and the
sampling method: Normal, Real-Time, Fast, Extended, and Period. The Normal, Real-Time,
Fast, and Extended modes are normally available, while the Period mode is available in
special cases only.
k Normal Mode
This general-purpose mode can be used for a wide range of sampling applications. The
Normal Mode is used for relatively short sampling. When the Normal Mode is selected, you
need to specify the sampling interval, the number of samples, and the timing of the start
trigger.
k Real-Time Mode
Basically, the Real-Time Mode is the same as the Normal Mode, except that it produces a
real-time graph of data as it is sampled. Use this mode when you need to graphically monitor
changes in sampled values as they are being sampled.
k Fast Mode
Use this mode when sampling a sound waveform or when other very fast sampling is
required. This mode can be selected only when CH1 or MIC is being used for sampling. This
mode is selected automatically whenever sampling is performed using the microphone. In
this mode, the sampling interval can be set to a very short interval in the range of 20 애sec to
500 애sec.

Setup
k Extended Mode
The Extended Mode is the opposite of the Fast Mode in that it allows setting of a long
sampling interval. In this mode, the sampling interval can be set in a range of 5 to 240
minutes. This mode is best for sampling data like temperature or humidity over a long period.
k Period Mode
The Period Mode is for sampling data that changes periodically. Samples recorded by the
Period Mode differ from the samples recorded in other modes as shown below.

Period Mode
Unlike the other modes that record time and sampled values, the Period Mode records the
number of samples (1st sample, 2nd sample, and so on) and the intervals between samples.
For details, see “Period Mode Parameters” on page 3-7.
Tip
• If you display the Setup dialog box from the [Multiple] tab of the Sensor Setup window, the [Mode]
box will allow selection of the Normal, Real-Time, or Extended mode only.
• Note that the availability of modes depends on the sensor being used for sampling. Certain
sensors allow selection of particular modes only.
• The currently selected mode is shown in the status bar of the Sensor Setup window.

Sensor:
This parameter shows the sensor that is currently connected to the CH1
channel. This parameter cannot be changed manually. Sampling is
triggered in accordance with the input value of the sensor connected to
the CH1 channel. The timing of the trigger is controlled in accordance
with the following two parameters.
Trigger Threshold: Specify a threshold value to specify when sampling is triggered.
Trigger Edge:
Select either [Rising] (reaching the [Trigger Threshold] value from a value
less than it) or [Falling] (reaching the [Trigger Threshold] value from a
value greater than it) for this parameter.
Tip
• With this start trigger, executing a sampling operation initially enters the standby state, and
sampling does not start until sampled values cross the threshold in the specified direction (rising
or falling). When [Rising] is specified for [Trigger Edge], for example, sampling will not start if the
input value is already greater than the specified threshold value when the sampling operation is
executed. This is because the threshold has not been crossed after execution of the sampling
operation.
• When specifying the Trigger Threshold, be sure to specify a value that represents a relatively
significant change for the current or normally measured value. A threshold value that is too close
to the current or normally measured value can cause problems with triggering.

Trigger Threshold: Specify a threshold value to specify when sampling is triggered.
Trigger Level:
Select either [Above] (any value above the [Trigger Threshold] value) or
[Below] (any value below the [Trigger Threshold] value) for this
parameter.
Tip
• With this start trigger, sample triggering depends solely on whether the current input value is
greater than or less than the trigger value. When [Above] is specified for [Trigger Level], for
example, sampling will start immediately if the input value is already greater than the specified
threshold value when the sampling operation is executed.
• When specifying the Trigger Threshold, be sure to specify a value that represents a relatively
significant change for the current or normally measured value. A threshold value that is too close
to the current or normally measured value can cause problems with triggering.

• For information about operation when [CASIO] - [Speaker ( y = f (x))] is selected as the
sensor on the Sensor Setup window, see “6 Outputting a Function to the Speaker”. When
[CASIO] - [Speaker ( y = f (x))] is selected, sampling is not performed. Instead, the sound of
the waveform of a function input on the ClassPad is output from the EA-200’s speaker.
u To get ready for sampling
(1) Connect the EA-200 to your ClassPad.
(2) Turn on the EA-200.
(3) Connect the required sensor(s) in accordance with the setup you will be using for the
sampling operation.

Saving Sample Data
The data produced by an EA-200 sampling operation controlled from the E-Con EA-200
application is stored temporarily in the ClassPad’s [EConSamp] folder. This temporary data
is called the “current data”.
• Current data is saved using one or more variables, one for each of the channels that was
used for sampling. Variable names are assigned automatically in accordance with the
channel and sensor used for sampling.

You can use the [Current] tab to graph the current data after sampling is complete. For
information about graphing, see “8 Graphing Data”.
• Whenever you perform a new sampling operation, the current data of the channel you are
using is overwritten with the new data. If you want to keep a copy of sampled data, you
need to save the current data under a different name.
u To save the current data under a different name
Use the ClassPad Variable Manager to save the current data in the [EConSamp] folder
under a different name. For details, see the section about the Variable Manager in the
ClassPad 300/ClassPad 300 PLUS User’s Guide.

Outputting a Function to the Speaker
6 Outputting a Function to the Speaker
When [Speaker (y = f(x))] is selected on the [CASIO] tab of the Select Sensor dialog box,
sampling is not performed by a sensor. Instead, the sound of the waveform of a function
input on the ClassPad is output from the EA-200’s speaker.
u To output the waveform of a function through the speaker
(1) Connect the EA-200 to the ClassPad, and turn on the EA-200.
(2) Turn on the ClassPad, and start up the E-Con EA-200 application.
(3) Tap O and then [Graph Editor] (or tap !) to display the ClassPad Graph Editor
window.
(4) On the Graph Editor window, input the function (for example: y1 = sin (440·2·π·x)) that
will be output from the speaker into any of the available lines ( y1 to y20).
• When inputting a function, specify arguments (for sin, etc.) using radian units. This
function treats all arguments as radian values, regardless of the ClassPad’s angle
unit setting.
• For details about how to input expressions into the Graph Editor window, see the
section about the Graph & Table application in the ClassPad 300/ClassPad 300
PLUS User’s Guide.
(5) Tap the Sensor Setup window to make it active.
(6) Tap the [Sensor] box to display the Select Sensor dialog box.
(7) On the [CASIO] tab, select [Speaker (y = f(x))] and then tap [Set].
• This closes the Select Sensor dialog box and returns
to the Sensor Setup window, which now appears as
shown to the right.
(8) Tap the [±1.5Range] down arrow button, and then select [Auto] or [Manual] as required.
• Selecting [Auto] optimizes the function and output range during graphing of the
function on the ClassPad Graph window (not the E-Con Graph window) so the y-axis
range is from –1.5 to 1.5 (maximum allowable range for speaker output). This is the
setting you should normally use.

Outputting a Function to the Speaker
• When [Manual] is selected, the optimization performed by the [Auto] setting is not
performed. Because of this, you need to input a function and specify an output range
(x-value) that makes the y-axis range –1.5 to 1.5. An error occurs whenever the
y-axis is outside the range of –1.5 to 1.5.
(9) Tap the [Formula] down arrow button. On the menu that appears, select the line ( y1 to
y20) that contains the function you input in step (4).
(10) Specify the function output range (x-value).
• Tap the [Start] and input the start value in the input dialog box that appears. Tap the
[End] box and then input an end value.
(11) Tap V.
• This displays the Output Frequency dialog box.
(12) Specify the output frequency on the dialog box.
• Input a percent value for the output frequency value you want. To output the original
sound as-is, specify 100%. To raise the original sound by one octave, input a value of
200%. To lower the original sound by one octave, input a value of 50%.
(13) Tap [OK].
• This displays a dialog box like the one shown to the
right.
(14) Tap [OK].
• This outputs the range specified by the function as a sound through the EA-200’s
built-in speaker.
• To terminate sound output, press the EA-200 [START/STOP] key.
Tip
• To store the setup you configured in steps (1) through (10) in memory, tap [SetupMem] on the
menu bar, and then tap [Store].
See “4 Using Setup Memory” for more information.
• The [Setup] menu is unavailable while [Speaker ( y= f (x))] is selected on the [CASIO] tab of the
Select Sensor dialog box.

Graphing Data
8 Graphing Data
This chapter explains how to configure graph parameters on the E-Con Graph Editor
window, and how to draw a graph on the E-Con Graph window.
E-Con Graph Editor Window
To graph sample data, you first need to tap the c button and display the E-Con Graph
Editor window, where you can select the sample data you want to graph.
The E-Con Graph Editor window has three tabs: [Current], [Normal], and [Compare].
Each of the tabs is described in detail below.
Tip
• Note that each time you perform a sampling operation, all of the current data on the [Current] tab
(or the sampled data you recalled for each graph) is cleared and replaced with the newly
sampled data. A sampling operation does not have any affect on the [Normal] tab and [Compare]
tab.
k [Current] Tab
The [Current] tab shows the current data (page 5-5). Use this tab when you want to draw a
graph of the current data following a sampling operation.
The [Current] tab can be either of the two styles shown below.
Gph1, Gph2, Gph3 Style
This is the same style as the [Normal] tab (see page 8-3).
This is the style that is displayed following sampling with most sensors. This style also
appears if you have not performed a sampling operation to produce current data, and
following the Clear All operation (page 8-10).
Except for the fact that the [Current] tab Gph1, Gph2, and Gph3 graph data is replaced by
the latest sampling operation, the operations for this tab style are identical to those for the
[Normal] tab.
20040201
20031201
8-2
Graphing Data
Upper/Lower Style
This is the same style as the [Compare] tab (see page 8-4).
This style appears in the following cases only.
• When sampling is performed with [CASIO] - [Speaker (Sample Data)] specified as the
sensor
• When sampling is performed with [CASIO]- [Microphone] specified as the sensor, with the
[FFT Graph] setting turned on.
• When sampling is performed with [Vernier]-[Microphone] specified as the sensor, with the
[FFT Graph] setting turned on.
Except for the fact that the [Current] tab Upper and Lower graph data is replaced by the
latest sampling operation using the above sensors, the operations for this tab style are
identical to those for the [Compare] tab.
Tip
• The following explains how data is allocated to the [Upper] and [Lower] graphs in accordance
with the sensor used for sampling.
[CASIO] - [Speaker (Sample Data)] Sensor
Upper: MIC (current data)
Lower: Sound (Conversion data based on Upper current data)
[CASIO] - [Microphone] Sensor, [FFT Graph] Turned On
Upper: MIC (current data)
Lower: FFT (current data)
[Vernier] - [Microphone] Sensor, [FFT Graph] Turned On
Upper: CH1 (current data)
Lower: FFT (current data)
For information about [Sound], see “[Compare] Tab” on page 8-4.
20031201

Graphing Data
k [Normal] Tab
The [Normal] tab is for recalling previously saved sampled data (or current data) for
graphing. You can draw up to three graphs at the same time using this tab.
Graphs
You can draw the following types of graphs using the [Normal] tab.
• Different sampled data can be recalled and assigned to each of the graphs (Gph1, Gph2,
Gph3) and graphed at the same time.
• You can use this tab to draw a single graph, or to draw two or three graphs at the same
time.
• For Gph2 and Gph3, you can assign Gph1 first derivative (d/dt) or second derivative
(d2/dt2) data. The assigned differential data can be graphed at the same time with the
sample data assigned to Gph1.
Example of graph using [Normal] tab settings
20031201

Graphing Data
k [Compare] Tab
Like the [Normal] tab, the [Compare] tab lets you for recall previously saved sampled data
(or current data) for graphing. You can draw up to two graphs at the same time using this
tab.
Graphs
You can draw the following types of graphs using the [Compare] tab.
• Different sampled data can be recalled and assigned to each of the graphs (Upper and
Lower) and graphed at the same time.
• You can use this tab to draw a single graph or to draw two graphs at the same time.
• For the Lower graph, you can assign Upper data first derivative (d/dt) or second derivative
(d2/dt2) data, or waveform (Sound) data converted from the Upper graph data so it can be
output from the speaker. The assigned data can be graphed at the same time with the
Upper data.
• Sound can be assigned to the Lower graph only when the sampled data assigned to the
Upper graph is MIC data (data sampled using the EA-200’s built-in microphone).

View Window
The E-Con EA-200 application uses View Window settings that are
independent of the View Window settings (O - [Settings] - [View
Window]) for the ClassPad Graph window.
This parameter specifies whether or not View Window settings of
the E-Con Graph Window (source graph) should also be applied to
the ClassPad’s View Window (result graph). The following explains
the two settings that are possible for this parameter.
Auto:
This option overwrites the View Window settings of the
ClassPad with the View Window settings of the E-Con
Graph Window.
This setting makes it possible to apply the View Window
settings used to draw the source graph with Fourier series
expansion on the E-Con Graph window to draw a result
graph on the ClassPad Graph window using the function
obtained by Fourier series expansion.
Manual: Selecting this option causes the current ClassPad View
Window settings to remain unchanged.
In order to obtain a result graph that resembles the source
graph, make sure that the start point and end point that you
specify for the source graph is one period of the graph.
