Background

Works out of the box with E-Prime, SuperLab, Presentation, Inquisit, PsychoPy or any other software that can read and write to a standard serial port to send simple TTL event marks/TTL triggers.

*Remember although our USB TTL Modules hardware is millisecond accurate and helps you produce simple event marks in your experiments it cannot automatically correct for any mistimings that are inherent within the experiment generator or other hardware you use. In short it does not guarantee that your event marks or triggers are accurate as your experiment generator is responsible to all timings and all it provides is a simple USB-TTL interface between your computer and third party equipment.

For example, if your experiment generator presents an image and does not produce an event mark in a timely fashion, your OS intervenes, or an anti-virus check runs, your event marks will remain inaccurate regardless of the quality of the event marking device. What | Why | How

For self-validation you should independently check the accuracy and consistency of your experiment generators presentation and response event marking with a Black Box ToolKit v3 together with a BBTK USB TTL module.

To independently TTL event mark stimuli and responses with sub-millisecond accuracy you should use our mBBTK v2. The unique mBBTK v2 takes over all timing and event marking duties from any experiment generator so you can be 100% sure of your presentation, synchronization, response timings and event marks.
