Hi all,
I have a BNC 2110 that is picking up acoustic signals and triggers when a signal has a certain amplitude, I also have a camera i would like to trigger in sync with the BNC 2110 so I can see the event that caused this high amplitude. I notice there is a section on the board titled "Trigger / Counter", I have read some documentation on it and I am under the impression that whenever the BNC 2110 reaches its trigger point it immidiately sends a signal through this port, the documentation was very vague however I want this confirmed before I go ahead and buy an appropriate camera. Also how large is the trigger signal??

Hi
Thank you for the quick response, I am using a NI PCI 6133 card, the trigger level for the audio (input) is 0.5-1 volt, and the trigger level for the camera (output so that the camera will activate as soon as the audio triggers) I don't know yet since I haven't purchased the camera, however I have several amplifiers the trigger out shouldn't be a problem
Thanks

The 6133 (and most of our DAQ devices) uses TTL logic levels for the digital lines (including triggers), so this will be around 0 Volts low and 5 Volts High.
