We want to send trigger generated by stimulus run in PC to USB receiver, so we can record the EEG data as well as the trigger information in Acitiview2. I wonder if it is possible using the COM port in PC other than parallel port. If it is possible, how can I make the cable.
Moreover, for example,if 1 represents event occurs, is it right just send [1 0 1 0] to the COM if we want to say the fist and third event occurs and the second and fourth event don't occur.
Thank you for any help.
