we've been using ADC-212/3s on several test rigs for fuel cells for years. the application is current interrupt measurement of the electrolyte resistance. for this and external trigger is used.
without too much knowledge of the source code running under LabView 6i we recently upgraded to LabView 8. This caused an error in functionality of the oscilloscope: the trigger only works once. Running the picoscope software works fine. Upgrading to the latest drivers did not solve the problem.
I still believe this is a labview problem. The driver works fine as displayed when running PicoScope software. I will have to look more closely at the VI for the 212.
We are looking at overhauling our Labview example code to improve functionality.
Best regards,

My fault your initial response did not work for me: inserting the close_ function gave no arguments by default. Little did I know that port number was required. Once reading the function declaration I added the proper argument and it worked straight away.
