AIA’s USB3 Vision camera interface standard is based on the USB 3.0 consumer hardware. The USB 3.0 interface (SuperSpeed USB) has USB 3.0 ports becoming standard on most PCs, AIA reports. It offers bandwidth of 350 MB/s. USB3 Vision, like GigE Vision, does not require a frame grabber. The standard covers four basic operations: device discovery, device control, event handling and streaming data. A device can optionally support device functionality with USB 2.0. Both power and data are transmitted over the same cable with possible cable lengths of five meters over passive cables and 10 meters or more using active cables. The standard defines the mechanics of screw locks on the micro-USB 3.0 connector. The standard will give users plug and play capability using components from different manufacturers.
The USB3 Vision standard is available for free download on the AIA Web site.
