All of the explanations provided here assume that you are already familiar with the operating precautions, terminology, and operational procedures of the calculator and the EA-200.

1 E-CON2 Overview

- From the Main Menu, select E-CON2 to enter the E-CON2 Mode.

E-CON2 Main Menu

- The “E-CON2 Mode” provides the functions listed below for simple and more efficient data sampling using the CASIO EA-200.

• F1(SET) ...... Displays a screen for setting up the EA-200.

• F2 (MEM) ...... Displays a screen for saving EA-200 setup data under a file name.
  • F3 (PROG) ..... Performs program conversion.

• This function can be used to convert EA-200 setup data configured using E-CON2 to an EA-200 control program (or EA-100 control program) that can run on the fx-9860G SD/fx-9860G.

• It also can be used to convert data to a program that can be run on a CFX-9850 Series/fx-7400 Series calculator.

- F4 (STRT) ..... Starts data collection.

- F5 (GRPH) ..... Graphs data sampled by the EA-200, and provides tools for analyzing graphs. Graph Analysis tools include calculation of periodic frequency, various types of regression, Fourier series calculation, and more.

- F6 (HELP) ..... Displays E-CON2 help.

- Pressing the OPTN key (Setup Preview) or a cursor key while the E-CON2 main menu is on the screen displays a preview dialog box that shows the contents of the setup in the current setup memory area.

To close the preview dialog box, press EXIT.

Note

For details about setup data and the current setup memory area, see "6 Using Setup Memory" (page 6-1).

About online help

Pressing the F6(HELP) key displays online help about the E-CON2 Mode.

2 Using the Setup Wizard

This section explains how to use the Setup Wizard to configure the EA-200 setup quickly and easily simply by replying to questions as they appear.

If you need more control over specific sampling parameters, you should consider using the Advanced Setup procedure on page 3-1.

■Setup Wizard Parameters

Setup Wizard lets you make changes to the following three EA-200 basic sampling parameters using an interactive wizard format.

• Sensor (Select Sensor):
  Specify a CASIO or VERNIER* sensor from a menu of choices.
  *Vernier Software & Technology
  • Total Sampling Time:
  Specify a value within the range of 0.01 second to 30 days.
• Sampling Time Unit (Select Unit):

Specify seconds (sec), minutes (min), hours (hour), or days (day) as the time unit of the value you input for the total sampling time (Total Sampling Time).

Note

For some sensors (EA-200 built-in microphone, Vernier PhotoGate, etc.), sampling parameters are different from those shown above. The differences between sampling parameters and setup procedures for each sensor are described in this section.

Setup Wizard Rules

Note the following rules whenever you use the Setup Wizard.

• The EA-200 sampling channel is CH1 or SONIC.
• The trigger for a Setup Wizard setup is always the EXE key.

- To configure an EA-200 setup using Setup Wizard

Before getting started...

• Before starting the procedure below, make sure you first decide if you want to start sampling immediately using the setup you configure with Setup Wizard, or if you want to store the setup for later sampling.
• See sections 6-1, 7-1, and 8-1 of this manual for information about procedures required to start sampling and to store a setup. We recommend that you read through the entire procedure first, referencing the other sections and pages as noted, before actually trying to perform it.

• To terminate Setup Wizard part way through and cancel the setup, press SHIFT EXIT (QUIT).

• Display the E-CON2 main menu (page 1-1).

• Press F1 (SET) and then F1 (WIZ).

- This launches the Setup Wizard and displays the "Select Sensor" screen.

1. Press F1 to specify a CASIO sensor or F2 to specify a Vernier sensor.

- Pressing either key will display the corresponding sensor list. The following shows the sensor list that appears when you press F1.

1. Specify the sensor you want to use.

Use the ▲ and ▼ cursor keys to move the highlighting to the sensor you want to use, and then press EXE.

- If the sensor you specified has more than one option (more detailed specifications, such as sampling unit, mode, etc.), an option list will appear on the display at this time. If this happens, advance to step 5 (where you will see an example of the screen that appears when you select [F1] - [Temperature] in step 4).

- If the "Input Total Sampling Interval" screen appears, skip to step 6.

1. Select the options for the sensor you specified in step 4.

Use the ▲ and ▼ cursor keys to move the highlighting to the option you want to select, and then press EXE.

- If the "Input Total Sampling Interval" screen appears, advance to step 6.

Important!

When special settings are required by the sensor and/or option you select, other screens other than the “Input Total Sampling Interval” screen will appear on the display. The following shows where you should go to find information about the operations you need to perform for each sensor/option selection.

If you select this sensor/option: Go here for	more information:
[CASIO] - [Microphone] - [Sound wave & FFT]	“Using Setup Wizard to Configure Settings for FFT (Frequency Characteristics) Data Sampling” on page 2-5
[CASIO] - [Microphone] - [FFT only]
[VERNIER] - [Photogate] - [Gate]	“To configure a setup for PhotoGate alone” on page 2-6
[VERNIER] - [Photogate] - [Pulley]	“To configure a setup for PhotoGate and Smart Pulley” on page 2-7
[CASIO] - [Speaker] - [y=f(x)]	“Outputting the Waveform of a Function through the Speaker” on page 2-8

1. Use the number input keys to input the total sampling time. Just input a value.

In step 8 of this procedure, you will be able to specify the unit (seconds, minutes, hours, days) of the value you input here.

Note

• With some sensors ([CASIO] - [Microphone] - [Sound wave], etc.) sampling time is limited to a few seconds. The unit for such a sensor is always seconds, and so the "Select Unit" screen does not appear.

• If you specify a total sampling time value in the range of 10 seconds to 23 hours, 59 minutes, 59 seconds, real-time graphing will be performed during sampling. This is the same as selecting the Realtime Mode on the “Advanced Setup” screen.

• After inputting total sampling time value you want, press EXE. This displays the "Select Unit" screen.

1. Use number keys ① through ④ to specify the unit for the value you specified in step 6.

- This displays a confirmation screen like the one shown below.

1. If there is not problem with the contents of the confirmation screen, press F1.

If you need to change the setup, press F6 or EXIT. This will return to the screen in step 4 (for setting the total sampling interval), where you can change the setting.

- Pressing F1 will take you to the final Setup Wizard screen.

1. Press number keys described below to specify what you want to do with the setup you have configured.

① (Start Setup) ...... Starts sampling using the setup (page 8-1)
② (Save Setup-MEM) ..... Saves the setup (page 6-1)
③ (Convert Program) ..... Converts the setup to a program (page 7-1)

■Using Setup Wizard to Configure Settings for FFT (Frequency Characteristics) Data Sampling

When you perform sound sampling executed the EA-200's built-in microphone (by specifying [CASIO] - [Microphone] as the sensor), Setup Wizard will provide you with three options: [Sound wave], [Sound wave & FFT], and [FFT only]. "Sound wave" records the following two dimensions for the sampled sound data: elapsed time (horizontal axis) and volume (vertical axis). "FFT" records the following two dimensions: frequency (horizontal axis) and volume (vertical axis).

The following shows the settings for recording FFT data.

1. Perform the first two steps of the procedure under "To configure an EA-200 setup using Setup Wizard" on page 2-2.
2. On the "Select Sensor" screen, select [CASIO] - [Microphone] - [Sound wave & FFT] or [CASIO] - [Microphone] - [FFT only].

- This causes a "Select FFT Range" screen to appear.

- You can select one of four settings for FFT Range. The setting you select will automatically apply the applicable fixed parameters shown below.

Setting Parameter	2 - 1000 Hz: F1	4 - 2000 Hz: F2	6 - 3000 Hz: F3	8 - 4000 Hz: F4
Frequency pitch	2 Hz	4 Hz	6 Hz	8 Hz
Frequency max	1000 Hz	2000 Hz	3000 Hz	4000 Hz
Sampling interval	61 μsec	31 μsec	20 μsec	31 μsec
Number of samples	8192	8192	8192	4096

The following explains the meaning of each parameter.

Frequency pitch: Pitch in Hz at which sampling is performed

Frequency max: Upper limit of sampling frequency (lower limit is fixed at 0 Hz)

Sampling interval: Interval in µ seconds at which sampling is performed

Number of samples: Number of times sampling is performed

1. Use function keys F1 through F4 to select an FFT Range setting.

- Selecting an FFT Range causes the final Setup Wizard screen to appear.

1. Perform step 10 under "To configure an EA-200 setup using Setup Wizard" on page 2-2 to finalize the procedure.

■Using Setup Wizard to Configure a PhotoGate Setup

Connection of a Vernier PhotoGate requires configuration of setup parameters that are slightly different from parameters for other types of sensors.

- To configure a setup for PhotoGate alone

1. Perform the first two steps of the procedure under "To configure an EA-200 setup using Setup Wizard" on page 2-2.
2. On the "Select Sensor" screen, select [VERNIER] - [Photogate] - [Gate].

- This displays a screen where you specify whether PhotoGate is connected to the CH1 or SONIC channel.

1. Press F1 to specify CH1 or F2 to specify SONIC.

- This causes a "Gate Status" screen to appear.

• “Open” means the photo path is not blocked, while “Close” means the photo path is blocked.
• The gate status defines what PhotoGate status should cause timing to start, and what status should cause timing to stop.

Open-Open ..... Timing starts when the gate opens, and continues until it closes and then opens again.

Open-Close ..... Timing starts when the gate opens, and continues until it closes.

Close-Open ..... Timing starts when the gate closes, and continues until it opens.

Close-Close ..... Timing starts when the gate closes, and continues until it opens and then closes again.

1. Use function keys F1 through F4 to select a Gate Status setting.

- Selecting a gate status causes a screen for specifying the number of samples to appear.

1. Input an integer in the range of 1 to 255 to specify the number of samples.
2. Perform step 10 under "To configure an EA-200 setup using Setup Wizard" on page 2-2 to finalize the procedure.

- To configure a setup for PhotoGate and Smart Pulley

1. Perform the first two steps of the procedure under "To configure an EA-200 setup using Setup Wizard" on page 2-2.
2. On the "Select Sensor" screen, select [VERNIER] - [Photogate] - [Pulley].

- This causes an "Input Distance(m)" screen to appear.

12 Calling E-CON2 Functions from an eActivity

You can call E-CON2 functions from an eActivity by including an “Econ strip” in the eActivity file. The following describes each of the four available Econ strips.

•Econ SetupWizard strip

This strip calls the E-CON2 Setup Wizard. The Econ Setup Wizard strip makes it possible to perform the following series of operations from the eActivity: EA-200 setup using the Setup Wizard → Sampling → Graphing.

•Econ AdvancedSetup strip

This strip calls the E-CON2 Advanced Setup screen. The Advanced Setup provides access to almost all executable functions (except for the program converter), including detailed EA-200 setup and sampling execution; graphing and Graph Analysis Tools; simultaneous sampling with multiple sensors using the MULTIMETER Mode, etc.

•Econ Sampling strip

This strip records on set of EA-200 setup information configured using Advanced Setup, and performs sampling. Once setup information is recorded to this type of strip, sampling starts immediately based on the recorded setup information the next time the strip is executed.

•Econ Graph strip

This strip graphs sampled data that is recorded in the strip. The sampled data is recorded to the strip the first time the strip is executed.

This section explains how to insert each type of Econ strip into an eActivity file, and how to use inserted Econ strips. For details about eActivity operations, see “Chapter 10 eActivity” in the manual that comes with the fx-9860G SD or fx-9860G.
