What are you trying to achieve?:
I am running an EEG study, a one-back task. I wantt to mark each stimulus by using port function.

What specifically went wrong when you tried that?:
Include pasted full error message if possible. “That didn’t work” is not enough information.

Now the problem is the behavioural PC only can send the trigger of the first stimulus to the recording PC. I don’t know what can be caused this problem? hope I can get some help from you. thank you.
