Connecting Psychopy and CAPTIV

Does anyone out there ever used CAPTIV to collect psychophysiological measures?
I’m trying to connect PsychoPy to CAPTIV. I need to send a trigger from PsychoPy to CAPTIV so it can start recording psychophysiological measures at the same time I play a video.
I looked at the manual and tried to use the p-port as output but I really don’t know how to do it. It seems that I should enter the address of the p port but I don’t know how to find it.
I’ll be immensely grateful if any of you could give me a hint.

Thanks a lot for your help!
