Hi all. I'm trying to send triggers to the BioPac system for EEG events in a Flanker Task that I have programmed in Eprime. I was able to successfully send triggers with a serial to db9 port on a separate system last year. However, this year we need to switch to the biopac system, meaning we bought a USB TTL module. It says the outputs are 2-9 and the inputs are 10-17. Any idea what trigger codes I would need Eprime to send to make this work?
