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.
1 Slide the EA-200 [ON/OFF] switch to turn on power.
2 EA-200 receives Command 0 sent from the calculator.
• This initializes the EA-200 setup.
3 EA-200 receives Command 1 sent from the calculator.
• This configures EA-200 channel settings.
4 EA-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.
5 Press 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.
6 Sample 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.
