Some experimental lab frameworks also have historically used PC parallel ports, because these existed on old PC platforms. However NO current PCs offer built in hardware PC ports. On the other hand, various types of external parallel interface ports are available, both as usb port dongles, and as actual PCI cards,
All such interfaces will likely add a small amount of delay before the data appears at the PC app. With the usb delay being larger than the card delay.
The previous link I gave for external trigger on Cyton, however, will precisely correlate with the EEG being sampled at that time. Since the 3 Aux channels are sampled at the same moment in time as the EEG.

Arno, hi.
Cyton has 3 'Aux' channel inputs that can be used as 'external triggers' or event inputs.

What types of OpenSesame 'events' are you working with?
Regards, William
