12. How much and how often do I want the ZENO

-3200 to perform the configuration; i.e., what Sample

Interval, Sample Duration and Sample Offset will be used?

Other questions may arise, or some may not be important; but each of the listed questions should be

answered so that "no stone is left uncovered."

For an illustration of creating a simple configuration, let's use the configuration that was used throughout

Part One of the Tutorial Section.

First, we must answer the 12 questions asked in the preceding paragraphs:

1. We need the ZENO

-3200 to measure its internal temperature and battery voltage, average the data,

and log and transmit the data at the end of each Sample Interval.

2. There are two sensors: internal temperature and battery voltage. Each sensor is an internal (built-in)

analog sensor.

3. In this case, each sensor is a built-in analog sensor internally connected to the 12-bit Analog-to-

Digital Converter (ADC).

4. Each sensor needs to be read once per second.

5. No external connections to the ZENO

-3200 are necessary since each sensor is built-in.

6. Each internal sensor is powered internally. It is not necessary to control the power to each built-in

sensor.

7. We need to view the average value of all the readings taken from each sensor over the course of the

Sample Interval.

8. To obtain the average value of all the readings taken from each sensor, two Average Processes will

need to be configured. (One Average Process per sensor.)

9. The average internal temperature and average battery voltage need to be logged in each data record at

the end of each Sample Interval.

10. The average internal temperature and average battery voltage need to be transmitted at the end of

each Sample Interval. This is the same data that is being logged.

11. The ZENO

-3200 needs to transmit each data record at the end of the Sample Duration.

12. We need the ZENO

-3200 to perform all data collection once a minute and to measure the sensors for

55 seconds before logging and transmitting the collected and processed data.

As you can see, answering those 12 key questions will make the creation of this configuration very easy.

3.2.2. Data Flow within the ZENO

-3200

The general flow of the ZENO

-3200 begins with 1) collecting data from sensor, 2) processing the

collected data, and 3) logging and transmitting the collected and processed data. This is the best way to

create a configuration and is illustrated as a "recipe card" below:

Refer to Section 3.1.
