We typically recommend purchasing an I/O card and using its output to connect to EEG equipment. You’ll need a custom cable. You’d create an event in SuperLab and set its type to Digital Output.
However, this Fall we’ll be introducing a new product called StimTracker that will come with an interface to one of four different vendors, including ADInstruments. We have successfully tested StimTracker with PowerLab at their office in Sydney. I don’t have a firm date for StimTracker’s release.
