Interfacing Eprime 3.0 with BIOPAC via a USB TTL interface blackbox toolkit

[Nadia G-M]

Hello all,

I am hoping to obtain some guidance on getting digital signals to be properly sent from Eprime to BIOPAC. I am using the USB TTL Module V1 from blackbox tool kit, and Eprime 3.0. I have set up my experiment in Eprime so that a trigger should be sent to BIOPAC whenever the image stimulus is presented (see images below). I have also set up the BIOPAC equipment as stated by their instructions to receive digital signals ( by turning on all digital channels). However, when I run the Eprime experiment, I do not seem to be getting any signals in BIOPAC.

Further, the USB TTL box continuously has the green light turned on- it does not seem to be blinking red or doing anything while the eprime experiment is run. Does anyone have any idea what I could be missing?

Did you ever get this sorted out? If not, I might have a few troubleshooting ideas after all this time.
