TTL signal to biopac

[revezzzz]

I finally got the I/O test to work today, but it is still not picking up a signal on Biopac. Would it be okay for me to email you a copy of my experiment so that you could make sure there are no small flaws that I am missing?

Sure, that's no problem. Just sent it to 'sales' at this domain.com.

However, you should be able to use the IO test utility to communicate with Biopac. So if that's not working, we're still missing something re: connections or syntax.

UPDATE:

We learned that the laptop running MediaLab had a parallel port not 'strong' enough to drive the BioPac box. So we switched to a desktop computer and had good luck communicating between Empirisoft's IOTest utility and the Biopac system.

After further testing and removal of a small typo in the experiment file, we were rewarded with a properly running MediaLab experiment which triggered the Biopac system at the appropriate time.
