Alternative PCI card to interface with Biopac

Thu May 22 19:58:45 UTC 2014

Erik,

Well, I guess the NI PCI-6503 is then used to access additional digital
and/or analog inputs or outputs of the biopac system. If you're only using
the connection between eprime and biopac for synchronization purposes or
encoding event markers, than the printer port connection should suffice. It
really depends on your experiment requirements if you need this additional
functionality.

Also, make sure to isolate the two systems properly if the biopac system is
connected to human subjects. In other words: a connection using the NI
PCI-6503 is only allowed if the adapter galvanically isolates the two
systems as required by FDA (or CE) guidelines (i.e. IEC 60601-1, 510(k) and
cousins). Also see http://www.biopac.com/FAQPage.ASP?id=6681&Src=Research

Make sure to consult an expert if you're not sure if your setup complies
with the relevant standards. Safety should be nr 1 on your priority list!

Best
Paul
