1. 计算器和个人计算机间数据通信
在计算器和计算机之间创建USB连接后，计算机会将计算器的永久存储器识别为大容量存储驱
动器。连接后可立即自动将主存储器内容读入永久存储器，这样可通过计算机访问主存储器数
据。在创建连接后，只可使用计算机操作在计算器和计算机间传输数据。
k 计算机系统最低要求
下列是计算机与计算器交换数据的最低要求。
• USB端口
• 运行下列某一操作系统。

Windows
10 （32位，64位）
OS X 10.10、OS X 10.11、macOS 10.12、macOS 10.13
k 在大容量存储器模式下连接和断开计算机
使用计算器附带的USB电缆连接到计算机。
重要！
当正在进行数据通信操作时，千万不要触碰USB插头和计算器屏幕。您手指上的静电会导致数
据通信操作中断。

(English)
Important!
• All explanations in this section assume that you are fully familiar with all calculator and Data
Logger (CMA CLAB* or CASIO EA-200) precautions, terminology, and operational procedures.
CLAB firmware must be version 2.10 or higher. Be sure to check the firmware version of your
CLAB before using it.
* For information about CMA and the CLAB Data Logger, visit http://cma-science.nl/.

E-CON4 Mode Overview
1. E-CON4 Mode Overview
The first time you enter the E-CON4 mode, a screen will appear for selecting a Data Logger.
Data Logger Selection Screen
Press 1(CLAB) or 2(EA-200) to select the Data Logger you want to use.
Selecting a Data Logger will cause the sampling screen (Time-based Sampling screen) to
appear.
Use the sampling screen to start sampling with the Data Logger and to view a graph of
samples.
CLAB EA-200
There are four sampling modes (sampling screens), described below.
1. Time-based Sampling ... Draws a graph simultaneously as sampling is performed. Note,
however, that the graph is drawn after sampling is finished when
CH1, 2, or 3, SONIC, or [START] key is specified as the trigger
source, or when the sampling interval is less than 0.2 seconds.
2. Fast Sampling ... Select to sample high-speed phenomena (sound, etc.)
3. Period Sampling ... Select to perform periodic sampling starting from a start trigger event
and ending with an end trigger event.
4. Manual Sampling ... Sampling is performed when the [EXE] key is pressed. Up to 100
samples can be taken by manual operation. Sampled data is stored in
the Statistics mode list. (CLAB only)
5. Mic & Speaker Mode ... Select to sample sound using the built-in microphone. You can
also output a waveform using the built-in speaker. (EA-200 only)
The Data Logger selection screen will not appear from the next time you enter the E-CON4
mode. Instead, the Time-based Sampling screen for the selected a Data Logger will appear
first.
To change the Data Logger, change the setting on the E-CON4 setup screen.
Connecting a Data Logger that is different from the one specified for the calculator will
cause an error message to appear. If this happens, use the setup screen to change the
“Data Logger” setting.

Calling E-CON4 Functions from an eActivity
13. Calling E-CON4 Functions from an eActivity
You can call E-CON4 functions from an eActivity by including an “E-CON strip” in the
eActivity file. The following describes each of the two available E-CON strips.
• E-CON Top strip
This strip calls the Time-based Sampling screen. This strip provides access to almost
all executable functions, including detailed Data Logger setup and sampling execution;
graphing and Graph Analysis Tools, etc.
Note
• Using an E-CON Top strip to configure a setup causes the setup information to be
registered in the applicable strip. This means that the next time you open the strip,
sampling can be performed in accordance with the previously configured setup
information.
• E-CON Result 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.
• E-CON Strip Memory Capacity Precautions
• The memory capacity of each E-CON strip is 22.5 KB. An error will occur if you perform
an operation that causes this capacity to be exceeded. Particular care is required
when handling a large number of samples, which can cause memory capacity to be
exceeded.
• Always make sure that FFT Graph is turned off whenever performing sampling with the
microphone. Leaving FFT Graph turned on cause memory capacity to be exceeded.
• If an error occurs, press !a(') to return to the eActivity workspace screen and
perform the procedure again.
• For information about checking the memory usage of each strip, see “To display the
strip memory usage screen” on page 10-21.
For details about eActivity operations, see Chapter 10 of this manual.
