Cedrus manufactures a StimTracker adapter board that makes it possible to interface with Biopac’s STP100C isolated digital interface using a standard DB37 ribbon cable. This document describes the signals that the adapter board makes available to STP100C.

If you have used SuperLab in the past to send event markers, you might be familiar with the Measurement Computing PCI-DIO24 card or its older version, the CIO-DIO24. These cards provide 24 I/O lines grouped into three ports: A, B, and C. StimTracker’s adapter board for the STP100C uses a DB37 connector that is compatible with these I/O cards. It generates the signals on the same pins as port B.

Please note that the STP100C also has a DB25 connector but it is not compatible with the DB25 connector on the MP35 and MP36. Connecting StimTracker’s MP35 adapter board to the STP100C will not work.
