Generating a TTL Pulse

[SoppierBrute9]

Hello,

I am trying to use an NI-6259 to generate a TTL pulse that will be sent to three cameras in order to sync them into capturing video at the same time. How do I go about doing this?

Can you send me a link to this example I can't seem to find it and want to make sure I am reading the correct example. Thank you for the help.

For a single start-trigger-style pulse, a Digital Output example will be just fine.

But if you need a continuous clock (i.e., a pulse *train*) for each camera frame, I'd recommend starting with the Counter Output examples.  (You could also use a counter task to generate a single triggering pulse, but there wouldn't necessarily be any advantage over a Digital task.)
