What specifically went wrong when you tried that?:
The program run success, but the triggers did not send to EEG recording system. There was no error. The port address in E-prime is &H378, I try port address = 0x378, but it also does not work.

Hello Tao Xia,
I am currently experiencing the same issue as you. Unfortunately, I could not figure out any solutions yet.
Would you mind sharing with me how to fix it please?
