## U3V Transfer Settings

You can edit the packet size and streaming channels for a USB3 Vision camera.

Right-click a USB3 Vision camera and then click U3V Transfer Setting to open the U3V Transfer setting window, and then configure Packet Size (value range: 64 to 20,480 KB, default value: 1024 KB) and Streaming Channel(s) (value range: 1 to 10, default value: 8) according to the performance of the USB frame grabber. The lower the performance of the USB frame grabber, the smaller the Packet Size and the more Streaming Channel(s) you should set so as to alleviate data transmission between and camera and the Software.
