TTL signal to biopac (case 14307)

[elegizer]

I've run a test with sendttl.csv, and Biopac read the ttl signal correctly while I monitor the signals.
It is ok to make a certain markers with it. but It would be better if I could trigger the Biopac using DirectRT.


Thank you

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.
