The GRAB-D-USB3.1-HUB-4X is a 4 port USB3.1 Gen 2 hub that supports speeds of USB 3.1 SuperSpeed Plus (10Gbps), SuperSpeed (5Gbps), USB 2.0 Hi-Speed (480Mbps). It has a wide powerrange between 9-24VDC. The powersupply is not included. It includes a USB Type-A to Micro B cable is included. This hub is unique because you have the following options:
Option 1, use the hub as a standard USB3 hub
With the standard cable that is included you can use this hub as a standard USB3 hub. This means when connecting mulitple cameras the bandwith will be shared for the connected cameras. A 20MP camera can run max 19fps, when connecting 2x 20MP camera, the framerate of each camera drops to 10fps.
Option 2, use the hub in USB3.1 10Gbps mode to connect multiple cameras without dropping framerate
To use the hub in USB3.1 superspeed plus 10Gbps mode, a USB Type-C to micro-B 3.1 Gen2-kabel ( CABLE-A-USB3.1C-0.9M) is required. Standard, this cable is not included. You can add it as an option. Please note that this cable has no screwlock connection. In this setup, the link between the USB-C port of the Laptop and USB3.1 hub is 2x higher (10Gbps) than standard. The link between the camera and the hub is 5Gbps. As a result you can operate two 20MP cameras at full 19fps framerate, from just one single USB-C port of a laptop. In our test setup, we are able to acquire from 1 single USB-C port simultaneously:
- 12MP camera running at 32fps
- 20MP camera running at 19fps
- 10MP camera running at 14fps
In total we acquire 12*32+20*19+10*14= 904 MegaByte / second through the single USB3.1 Type-C port.
