3. Data Send Priority
1. Real-time Type
(Selected using Command 12)
Channel Priority: CH1, CH2, CH3, SONIC, DIG IN, sampling time
• Variable (1 data)
Sends the data of the channel with highest priority among {CH1, CH2, CH3,
SONIC, DIG IN, sampling time}.
The data with the second highest and subsequent priorities is not sent.
• List (N line data)
{CH1 data n, CH2 data n, CH3 data n, SONIC data n, DIG IN data n, sampling
time n}
(n: number of samples at the point that request is made)
2. Non Real-time Type
(Selected using Command 12)
Channel Priority: Sampling time, mic, CH1, CH2, CH3, SONIC, DIG IN
• Variable (1 data)
First sends the oldest data on the highest priority channel.
Next sends the next oldest data upon request.
Next channel data is sent after all the data of the current channel is sent.
• When List type data is requested part way through
The channel’s data is sent as a list.
• When Matrix type data is requested part way through
Sent as Matrix type.
• List (N line data)
Sends the data of the highest priority channel.
{CH* data1, CH* data2, CH* data3, … CH* data n}
Next sends the next highest priority channel’s data upon request.
* Sample data that is not configured is omitted.
* After everything is sent, returns to the beginning when a data request comes
in.

When using the EA-2
• Use the bundled AC adaptor.
• Minimum sampling interval is 0.02 sec.
(When the subject is 3 meters or less away.)
