Hi, For my MEG experiment the script sends trigger without problems. Though I’m not familiar with brain vision EEG system, maybe my setup for the parallel port could help?

My EEG recorder isn’t BrainVision . After I followed your previous steps, Amplifier shows SynAmps2/RT here and my EEG mark does not show up on the computer where it was recorded. Do you know what the cause is? I really need help.
