If you aren't ready to integrate AV-Trend yet due to old PC hardware, or you don't have a communication link to take advantage of the AV-Sync features (e.g., you're using a USB drive to carry minute data back and forth), you may need a way to transfer the minute data files from Digi-Trend to AirVision.

This method automates the E-DAS Import utility to operate on a predefined data directory on the AirVision Server, where minute data files and logbook .MDB files from Digi-Trend PCs can be ‘dropped’ for processing.

First, create a directory on the AirVision server for files to be dropped for processing. For this illustration, we will assume a shared directory and folder which appears to the server as “X:\IncomingDT”

Note that the import directory must retain a permanent copy of the original E-DAS configuration files. These files contain information regarding channel types that are used in the data conversion process.

Secondly, we will add a Scheduled Command Line Task to the Task Scheduler to run the minute data import function on that directory. Use Configuration Editors->Task Scheduler and select “Scheduled Command Line Task.” Set an execution interval that you would like (say, hourly), give the task a descriptive name (“DigiTrend Minute Import”) and put in the following for the executable name and command line arguments:

Executable:
“C:\Program Files\Agilaire LLC\AirVision Server\EdasImporter.exe”

Command Line Arguments:
/P x:\IncomingDT /D Minute /M




Obviously, you would replace the appropriate import in the example with your directory path.


If you want to import logbook entries as well, create a Scheduled Command Line task just as before, and use this executable name and command line arguments:

Executable:
“C:\Program Files\Agilaire LLC\AirVision Server\EdasImporter.exe”

Command Line Arguments:
/P x:\IncomingLogbooks /D LogBook

After the conversion, data files will be placed in a “processed” subfolder that will be automatically created if needed. Files that failed the conversion step will be placed in a “failed” subfolder. If the conversion points to a shared network folder, you should manually create these subfolders, because the AirVision process may not have the rights to create the subfolders, which would cause an error.
