NIRS-EEG Splitter Trigger Cable

This NIRS-EEG Splitter Trigger Cable allows you to send TTL trigger markers from a stimulus presentation computer (running Presentation, E-Prime, PsychoPy, etc.) to the ActiveTwo (Biosemi) and a NIRS system from Shimadzu (FOIRE3000 or LABNIRS). The NIRS-EEG Splitter Trigger Cable splits 8 bits of information from the D-Sub 25 connector to 8 separate BNC connectors. Ground (GND) is shared between all BNC connectors and connected to pin 25 on the D-Sub 25 connector.

The output of the trigger cable is usually TTL (transistor-transistor logic), meaning 5 V for High and 0 V for Low.

The cable length is 5m. The pinout and the cable length can be adjusted upon request.
