OWL Software Driver
TrendReader software uses a software driver to communicate with OWL data loggers. The
software driver takes the form of two windows. The Status window, shown when you contact
the logger, is used to display the settings currently stored in the data logger. The Setup
window, shown when you select Edit Setup, is used to alter the current settings and apply the
changes to the data logger. The settings are divided into two main sections: Status and
Channel . Status contains information about sampling, memory and triggering. The channel of
the logger contains information about the description, equation and Realtime value, and range.
You can control the level of detail that you see for the settings by clicking on the "+" and "-"
buttons at the left side to expand and collapse the nodes.
When you want to clear the logger's memory and start a new logging session with new
parameters, select Edit Setup from TrendReader. In the Edit Logger Setup window, make
any necessary changes. To implement your changes, you can either click on Apply or OK .
OK will implement the changes and close the window whereas Apply will leave the window
open, thereby allowing you to make changes in other features.
When you backup a logger, a window pops up with a progress bar showing the time
remaining. However, OWL loggers store data in a compressed format and the application
does not know ahead of time how much data is stored. Therefore, the progress bar and time
remaining displayed may not be accurate.
