EEG Triggers via Labjack: How to do the Parallel Port DB25 connection

Hi @tstenner thanks for your answer. Using the arduino sounds very interesting and the DB25 terminal adapter you linked looks straight forward. This would be a low-cost solution indeed (and it would work under every OS I assume).

Two questions:

  1. Would you mind sharing the wiring of the Arduino Leonardo with that said adapter?
  2. Have you performed timing tests?

Browsing through your other answers in this forum, I also found this topic, in which an adapter by the BlackBoxToolKit company is also mentioned: https://www.blackboxtoolkit.com/usbttl.html

BBTK says this one can be used under Linux as well, albeit their “validation software” only works under Windows apparently. Perhaps this would be yet another solution.
