ZENO

-3200 USER MANUAL

Coastal Environmental Systems (206) 682-6048

Page 165

Coastal Environmental Systems recommends that any communications port

that is being used to collect data from a serial sensor should be excluded

from the User Interface.

184

If the ZENO

-3200 attempts to look for access to the User Interface on a communications port that is

configured to collect data from a serial sensor, the ZENO

-3200 may interfere with data collection to that

serial sensor.

10.3.6. User-Specified Sensor Name

Use of the Sensor Name field, Line Item #2 in each Sensor Record, is strictly optional. You can specify

up to an eight-character name for your particular sensor. The Sensor Name will appear adjacent to a

reference to the Sensor Record when it is used as an input to a Process Record or Data Output Record.

Coastal Environmental Systems recommends that you use this optional field

to specify a unique name for each Sensor Record in your sensor suite

because it makes it a lot easier to understand what your configuration is

doing.

10.3.7. Setting How Often To Read A Sensor--The Sensor Timing Loop

Three line items in each Sensor Record control how often readings are taken from a sensor, the number of

consecutive measurements taken during a single reading, and how many total readings can be taken

during Sample Duration. These are summarized below:

 Line Item #10: Sensor Sample Count

 Line Item #11: Maximum Number of Readings

 Line Item #12: Sensor Timing Loop

At the beginning of the Sample Duration, the ZENO

-3200 collects data

once from all configured Sensor Records. Subsequent measurements are

timed according to the Sensor Timing Loop specified by each Sensor Record

within the same Sample Duration.

This can be illustrated with a simple timing diagram. In the following diagram, the Sample Interval is set

to 20 seconds, the Sample Duration is set to 19 seconds and the Sensor Timing Loop period is set to 2.5

seconds. A total of 8 sensor readings can be made every 2.5 seconds through a Sample Duration of 19

seconds.
