This is the setting that I followed, http://www.biopac.com/visual-present...-the-mp150-100

Regarding the hardware setting, as you see in the picture, Biopac communicate with their software via Ethernet cable and TTL signals are communicate through parallel port between Medialab and Biopac.
In addition, using TTL test, I confirmed that the TTL signals that are send by the TTL test program are well monitored on Biopac's monitor at channel 8. As far as I know, Biopac detect the signal changes such as 0 to 1 or 1 to 0 depends on settings. And this change triggers data acquisition.
I will try in an experiment setting and feedback this to you tomorrow.
Thank you.
