Dear all, I need to send triggers through psychopy via the brain vision triggerbox to the brain vision recorder. When I use a triggerbox test software it works perfectly. However, I cannot find the right settings in psychopy builder to make it work. I use a laptop and the usb connection to the triggerbox is COM3. Any help would be so much appreciated. Below is the warning message from psychopy after trying to run the experiment.

Best,  
Peter
