We are trying to send triggers to a BioNex box which records peripheral physiology such as skin conductance, respiration, ECG etc. We are trying to send triggers on multiple occasions throughout our task including when a stimulus is presented, when a stimulus presentation ends, and when a participant answers questions/rating scales.
We have tried some other suggestions found on the internet but have been unsucsessful. We tried using the parallel port out in builder and then compiling that to python code which did not work. We are using the StartTech PEX1P2 parallel port card and have installed all the necessary drivers. We found the parallel port adress (LPT1 - 0378). Thanks for any help in advanced!
