E-CON Overview
4-1 E-CON Overview
•From the Main Menu, select E-CON to enter the E-CON Mode.
•The E-CON provides the functions listed below for simple and more efficient data
sampling using the CASIO EA-100.
•1(SETUP) ... Displays a screen for setting up the EA-100.
•2(MEM) ....... Displays a screen for saving EA-100 setup data under a file name.

a CFX-9850 Series/fx-7400 Series calculator, and to transfer the
data to the calculator.
•4(STA RT) .... Starts data collection.
•6(HELP) ...... Displays E-CON help.
•Pressing the Kkey (Setup Preview) or a cursor key while the E-CON main menu is on
the screen displays a preview dialog box that shows the contents of the setup in the

4-2 EA-100 Setup
You can use the E-CON Mode to set up the EA-100 for sampling and then start sampling
immediately or save the setup in calculator memory. You can use either of the following two
methods to set up the EA-100.
Setup Wizard: With this method, you set up the EA-100 simply by replying to
questions as they appear.
Advanced Setup: Advanced setup gives you control over a variety of sampling
parameters, which means you can set up the EA-100 for exactly the
type of sampling you want.
kUsing Setup Wizard to Create an EA-100 Setup
With Setup Wizard, you set up the EA-100 simply by replying to questions as they appear.
uSetup Wizard parameters
Setup Wizard lets you make changes to the following three EA-100 basic sampling
parameters using an interactive wizard format.
•Sensor (Select Sensor)
Specify a CASIO or VERNIER*1sensor from a menu of choices.
•Sampling Interval (Sampling Time)
When you have Photogate specified as the sensor type, you can specify the sampling
timing (Gate Status) and sampling time recording method (Record Time) with this
parameter.
•Number of Samples (Number of Samples)
You can specify a value from 1 to 255.
Note the following limitations that apply to a setup made using Setup Wizard.
•You can use Setup Wizard only when the EA-100 sampling channel is CH1 or SONIC.
•The trigger for a Setup Wizard setup is always the wkey.
•Sampling results are always stored in List 1 (for the sampling time) and List 2 (for
sample values).

uTo create an EA-100 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 create with Setup Wizard, or if you want to
store the setup for later sampling.
•See sections 4-3, 4-4, and 4-5 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-CON main menu.
2. Press 1(SETUP). This displays the “Setup EA-100” sub-menu.
3. Press b(Wizard). This displays the Setup Wizard initial screen.
4-2-2
EA-100 Setup
4. Press any key to start Setup Wizard and display the sensor specification screen.
•Press 1to specify a CASIO sensor, or 2to specify a VERNIER sensor. From the
menu of supported sensors that appears, select the one you want.
5. The screen that appears after you select a sensor in step 4 depends on whether or not
you specified “Photogate” as the sensor.
• If you did not specify “Photogate,” a screen for setting the sampling interval appears after
step 4.
1. Use the number keys to input the sampling interval.
•Inputting a value in the range of 0.52 to 300 enables real-time sampling. Inputting
a value outside this range enables non-real-time sampling.
2. Press w.
•If you specified “Photogate” as the sensor, a screen for setting the sampling timing
appears after step 4.
1. Press either 1(Open) or 2(Close) to specify the sampling timing. Pressing either
key advances to a screen for setting the time recording method.
•See online help (GATE TRIGGER STATUS HELP) for details about the Open and
Close settings.
2. Press 1(Abs) or 2(Rel) to specify the sampling time recording method.

6. After you complete step 5, a screen for setting the number of samples appears on the
display.
•Use the number keys to input the number of samples, and then press w.
7. After you complete step 6, a screen like the one shown below appears on the display.
•Press one of the function keys described below to specify what you want to do with the
setup you have created with the above steps.
•1(YES) ........ Starts sampling using the setup (page 4-5-1).
•2(NO) .......... Returns to the E-CON main menu (page 4-1-1).
•3(SAVE) ...... Saves the setup (page 4-3-1).
•4(PRGM) ..... Converts the setup to a program (page 4-4-1).
•Pressing 2(NO) in step 7 returns to the E-CON main menu and stores the setup in the
E-CON Mode’s current setup memory area. You can use the following function key
operations from the E-CON main menu to manipulate the contents of the current setup
memory area.
•2(MEM), then 2(SAVE)
....................... Saves the current setup memory area setup (page 4-3-1).
•3(PRGM) ..... Converts the setup in the current setup memory area to a program
(page 4-4-1).
•4(STA RT) .... Starts sampling using the setup in the current setup memory area
(page 4-5-1).
•Pressing 1(SETUP) and then c(Advan) displays an Advanced Setup screen for more
detailed control over the parameters that make up the setup in the current setup memory
area. See “Creating an EA-100 Setup Using Advanced Setup” for more information
about changing advanced setup parameters.
