I am using Superlab and a StimTracker in conjunction with the STP100C. I am a little unclear about the 6 TTL input lines. I’d like to know if these can be used to send event markers from Superlab to Aqcknowledge. I know that the USB cable can be used to create event markers on 3 channels, but I am interested in having more event markers. Everything I’ve read implies that the ethernet cord is used for button boxes, but I am just wondering if it can be used to pass a digital signal from Superlab to Acqknowledge as well.
