How to add an output port in Presentation

The output port is used to send task-related codes to the EEG recording computer. In this way, event onsets are coupled with the EEG recording.

If no output port is specified, go to the ‘Settings’ tab in Presentation and select ‘Port’. Adding an output port can be done by clicking on ‘Add’ in the ‘Output Ports’ section. Select the Port that is specified below. Note that this can vary across labs.
