USB-TTL interface
Part #: USB-TTL

USB-TTL Interface is a USB module which provides 16 TTL I/O lines that can have up to millisecond accuracy. It may be used to replace parallel port interfaces, which are no longer common on computers. This interface may be used for custom programming or for sending/receiving information from E-Prime, SuperLab, or other stimulus presentation programs.

USB TTL Module | Millisecond accurate* event marking across up to 16 I/O lines

Gender Changer | Use to connect the USB-TTL to an STP100C for MP160/150 System, I/O Port on MP36/36R, or other 25-pin male device

USB Lead | Use to connect the USB-TTL Module to the Host PC
