I actually haven't checked the timing of the pulses with respect to the EEG data. I just compared the time at which MATLAB sent the signal using the GetSecs function to the time at which the triggers were received by Actiview (using EEGLAB code: received = [EEG.events.latency]/1000).
code for ...

Digital Input delays
Hello,
I am trying to send digital inputs to the EEG amp using MATLAB via the parallel port. I’ve run some timing test to check the delay between the time a pulse is sent by MATLAB and the time when it is received by the recording computer (Actiview). I have two questions:
Are the signals time ...
