I have the ADS7-V2 and I would like to trigger ADC data captures using its J5 SMA connector. What type of signal does it expect? I see the box to use a trigger in VisualAnalog, but so far I have not been able to get it to work. I can capture data by hitting the capture button in VisualAnalog, but I could not find anything here, on the wiki, in user guides, or in application notes that describe how to use the external trigger.
Thanks very much for your help,
