Using Commands

Basically, the EA-200 is controlled by commands from the connected calculator. This section explains how to send commands from the calculator to the EA-200.

To use a command, you store parameters as List data on the calculator, and then use the Send command to send the parameters to the EA-200.

EA-200 Operation

The following is an outline of the EA-200 command receive process.

1Slide the EA-200 [ON/OFF] switch to turn on power.

2EA-200 receives Command 0 sent from the calculator.

• This initializes the EA-200 setup.

3EA-200 receives Command 1 sent from the calculator.

• This configures EA-200 channel settings.

4EA-200 receives Command 3 sent from the calculator.

This configures EA-200 sampling conditions.

After sampling conditions are configured, the EA-200 enters the ready state.

5Press the EA-200 [START/STOP] key.

This puts the EA-200 into sampling mode.

Sampling ends in accordance with the sampling conditions configured in step 4.

6Sample data is sent from the EA-200 to the calculator in response to a Receive command.

Sending a Command

Example 1: To initialize the EA-200 setup

{0} List 1_ Stores {0} to List 1. 0 is the command number.

Send (List 1)_ Sending List 1 executes Command 0.

Example 2: To configure channel settings

{1, 1, 2} List 1_ Stores {1,1,2} to List 1. The first 1 is the command number, the second 1 is the channel number, and the 2 indicates use of the voltage probe.

Send (List 1)_ Sending List 1 executes Command 1.

Receive Data Command

As with command execution, all of the operations required to receive data from the EA-200 to the calculator are performed on the calculator.

You can transfer sampled data by executing the calculator's Receive command. Data is transferred in the sequence shown below.

Record Time CH1 CH2 CH3 SONIC

Receive (List 1)_ Stores transferred data into List 1 of the calculator.

Using the Voltage Probe, Temperature Probe, Optical Probe, and Motion Sensor (EA-2)

The following examples show how to use the temperature probe, voltage probe, optical probe, and “Motion Sensor (EA-2)”. Perform the procedures in each example by creating programs on the calculator.

Taking 60 samples at one-second intervals over one minute

(1) Send Command 0 to initialize the EA-200 setup.

{0} List 1_

Stores {0} to List 1. 0 is the command number.

Send (List 1)_

Sending List 1 executes Command 0.
