UZ3 – USB 3.0 Optibit Interface

The UZ3 provides a high speed, fiber optic connection to TDT processors and other System 3 devices through a standard USB 3.0 port. An alternative to the TDT desktop PCI interface card (PO5e), the UZ3 is perfect for use with a laptop in research applications where portability is important.

The UZ3 is a small, lightweight interface that draws power directly from the USB 3.0 bus; no external power supply is required. It offers the same high speed, real-time control of TDT System 3 equipment as our line of PC interface cards.

Use the UZ3 as your primary TDT equipment interface if you intend to control your research from a laptop. Or easily add a UZ3 if you would like to extend the functionality of your existing rig by carting it to different experimental environments.

Research Uses


  • Any application where laptop connectivity or portability is desired
