HSDIO trigger for repeated acqusition

I am using a PCI-6541 with the NI-HSDIO interface to attempt to acquire a signal. I would like to start the acqusition on a trigger signal for a set number of samples, download those samples, and start a new acqusition upon detection of another trigger from the same source. I managed to get streaming to memory without the re-trigger, and the start trigger works correctly, but it acquires continuously, not only upon detection of the trigger edge. How do I have to configure the system to achieve my goal?

 

Many thanks

 

Dave
