Send trigger via Cedrus Photodiode & stimtracker


I cannot find any info on how to send trigger through a cedrus photodiode.

The Photodiode is connected to the stimtracker, I can send, using the code component, triggers to ActiView (Biosemi) but I need to send from the photodiode as well.

This is done automatically by StimTracker; see this support note, Marking Onset of Visual Stimuli.

If you are looking to have the information sent back to PsychoPy as well via USB, this is possible on the newer StimTracker Duo and Quad (but not on the original StimTracker ST-100 model). See Enabling USB Output.
