Video I/O Hub


The DATAPixx2 is a complete multi-function data and video processing USB peripheral for vision research. In addition to a dual-display video processor, the DATAPixx2 includes an array of peripherals which often need to be synchronized to video during an experiment. These include a stereo audio stimulator, a button box port for precise reaction-time measurement, triggers for electrophysiology equipment, and a complete analog I/O subsystem. Because we implemented the video controller and peripheral control on the same circuit board, you can now successfully synchronize all of your subject I/O to video refresh with microsecond precision.

The DATAPixx2 video subsystem converts a dual-link DVI digital video input from the host computer (or laptop) into two dual-link DVI video outputs. The second dual-link DVI output head can show the tester a mirror of the primary display; or alternatively, the left/right halves of a wide DVI input image can be split onto the two displays, ensuring perfect frame synchronization between the left/right displays. To further support stereo applications, the DATAPixx2 also includes a standard VESA mini-DIN-3 connector to interface with stereo glasses.
