Greetings-
We're using Coulbourn physio equipment and have just upgraded to Windaq
physio acquisition software. In the past, we've been using some kind of
homemade circuit box to transmit a TTL signal from the parallel port of the
computer running MediaLab to the Coulbourn port (V19-16). Now we've got a new Coulbourn port (V19-02) and a DataQ DI720 USB acquisition system
especially for Windaq.

Here's my question-I'd like to make a new, more robust connection that will
allow us to send TTL signals from MediaLab to the new port. The homemade
box that we've been using is falling apart, the grad student that made it is
no longer around and none of us know how to build such a device. I thought
maybe someone here would know how this is done and could offer some advice. I've looked around on the web and haven't been able to find much.
Alternatively, if you know of anyone using a similar setup and
are comfortable connecting me with them, I can go that route.
Thanks a million.
