Features
Features	The Thunderbolt 3 to 1394 FireWire adapter brings your high-powered FireWire peripheral devices to life through your Thunderbolt 3 computer Save on peripheral upgrade costs by adapting legacy FireWire peripherals to Thunderbolt 3 devices Create an efficient workstation with extra displays, using the DisplayPort output and additional Thunderbolt 3 port Upgrade your peripheral connections without having to upgrade your chassis by just switching out your PCIe card Install the PCIe card easily with just a screwdriver and automatic driver installation Note: The expansion chassis does not support video cards. This expansion chassis does not provide full power delivery but will provide 15W of power, resulting in a slow charge to some laptops, such as the MacBook Pro. When the dock is connected to your host laptop, a charging icon may appear on your laptop's screen. This is only sufficient enough to charge your laptop in sleep state, and charging will require an extended time period. 5K support can only be achieved using a Thunderbolt 3 5K monitor. DisplayPort 5K monitors will not work with this expansion chassis. A 4K-capable display is required to achieve 4K x 2K resolution (4K is also known as 4K x 2K). Certain monitors may be limited to 4K at 30Hz when connecting through DisplayPort. These monitors include the following models: Dell P2715Q, Viewsonic VX2475Smhl-4K, Philips 288P6LJEB, LG 31MU97C-B, Asus PB287Q (these models will need to be set to 4K at 30Hz). When connecting a display to one of the Thunderbolt 3 USB-C ports, a USB-C video adapter might be required depending on the input of your display. Secondary Thunderbolt 3 port can also be used to connect USB 3.1 (10Gbps) USB-Type C devices, such as USB 3.1 Hubs. Backwards compatible with USB 3.0 (USB 3.1 Gen 1), and USB 2.0.
