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.

k 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).

Sensor-specific settings

The type of sensor you select with “Select Sensor” settings affects the settings of the Setup Wizard as described below.

Affects Setup Wizard settings like this:Selecting this with “Select Sensor”:

[CASIO] - [Mic]

[CASIO] - [SPEAKR] - [Sample]

[VERN] - [P-Gate] - [None]

[VERN] - [P-Gate] - [Pulley]

[CASIO] - [SPEAKR] - [Y=f(x)]

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 w key.

•The sampling time unit (Select Unit) becomes “sec” and cannot be changed.

•You must specify the sampling timing (Gate - Status) and number of samples (Number of Samples).

•For details, see “Using Setup Wizard to Configure a PhotoGate Setup” on page 2-3.

•You must specify the distance (Distance) only.

•For details, see “Using Setup Wizard to Configure a PhotoGate Setup” on page 2-3.

•Requires sampling that is completely different from that performed with a sensor.

•For details, see “Outputting the Waveform of a Function through the Speaker” on page 2-4.

u 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 !i(QUIT).

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

2. Press 1(Setup EA-200). This displays the “Setup EA-200” submenu.

3. Press b(Wizard). This displays the “Select Sensor” screen.

4. Press 1 to specify a CASIO sensor, or 2 to specify a Vernier sensor. Select the sensor you want from the menu of sensors that appears.

•Selecting a sensor (page 2-1) causes a screen for specifying the total sampling time to

appear.

5. Use the number input keys to input the total sampling time. Just input a value. You will be able to specify the unit (sec, min, hour, day) of the value you input here in step 7 of this procedure (see "Sensor-specific settings" on page 2-1).

Note

•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.

6. After inputting total sampling time value you want, press w. This displays the “Select Unit” screen.

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

b(Start Setup) ................ Starts sampling using the setup (page 8-1)

c(Save Setup-MEM) ...... Saves the setup (page 6-2)

d(Convert Program)....... Converts the setup to a program (page 7-1)

k 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.

u To configure a setup for PhotoGate alone

1. Perform the first three 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 [VERN] - [P-Gate] - [None].

•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 and

then opens again.

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

then closes again.

3. Use function keys 1 through 4 to select a Gate Status setting.

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

4. Input an integer in the range of 1 to 255 to specify the number of samples.

5. Perform step 8 under “To configure an EA-200 setup using Setup Wizard” on page 2-2 to finalize the procedure.

u To configure a setup for PhotoGate and Smart Pulley

1. Perform the first three 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 [VERN] - [P-Gate] - [Pulley].

3. Perform step 8 under “To configure an EA-200 setup using Setup Wizard” on page 2-2 to finalize the procedure.

k Outputting the Waveform of a Function through the Speaker

Normally, the Setup Wizard helps you configure setups for sensors connected to the EA-200. If you select [CASIO] - [SPEAKR] - [Y=f(x)] on the “Select Sensor” screen, however, it configures the EA-200 to output the sound that corresponds to a function that you input and graph on the calculator.

u To configure a setup for speaker output

1. Connect the data communication cable (SB-62) to the communication port of the calculator and the MASTER port of the EA-200.

2. Display the E-CON main menu (page 1-1), and then press 1(Setup EA-200).

•This displays the “Setup EA-200” submenu.

3. Press b(Wizard). This displays the Setup Wizard initial screen.

•The following settings are configured automatically: Ymin = –1.5 and Ymax = 1.5. Do not

change these settings.

6. Press w or i to advance to the graph function list.

7. In line “Y1”, input the function of the waveform for the sound you want to input.

•Note that the angle unit is always radians.

•Input a function where the value of “Y” is within the range of –1.5 to +1.5.

8. Press 6(DRAW) to graph the function.

•This graphs the function and displays a vertical cursor line as shown below. Use the

graph to specify the range that you want to output to the speaker.

9. Use the d and e cursor keys to move the cursor to the start point of the output, and then press w to register it.

10.Use the d and e cursor keys to move the cursor to the end point of the output, and then press w to register it.

•After you specify the start point and end point, a dialog box like the one shown below

appears on the display.

11. Input a percent value for the output frequency value you want.

•To output the original sound as-is, specify 100%. T o 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%.

12.After inputting an output frequency value, press w.

•This outputs the waveform between the start point and end point from the EA-200 speaker.

•If the sound you configured cannot be output for some reason, the message “Range

Error” will appear. Note that the supported output range is 200 to 4000Hz. If this happens, press i to scroll back through the previous setting screens and change the setup as required.

13.To terminate sound output, press the EA-200 [START/STOP] key.

•Pressing w after terminating sound output returns to the output frequency dialog box in

step 11.
