D-Link DUB-E255 USB-C to 2.5GbE Ethernet Adapter with Power Delivery

Add a Multi-Gigabit Link Without Losing Charging Add multi-Gigabit wired networking to a compatible laptop through USB-C. The D-Link DUB-E255 combines an RJ45 Ethernet connection with USB-C Power Delivery support in a compact adapter. Use it at a desk, in a meeting room or wherever a compatible wired network is available. Automatic speed negotiation lets the adapter work with supported slower links, while its PD connection accommodates a suitable charger without taking another port on the computer. Highlights Wired Networking RJ45 link up to 2.5 Gbps Automatic 10/100/1000/2500 Mbps negotiation Full duplex and Auto-MDI/MDI-X Connection and activity indicators Practical USB-C Connection USB-C host connector with integrated 18 cm cable Power Delivery capability up to 100 W USB-powered, hot-pluggable operation Key Features Make a Wired Network Available The RJ45 socket adds an Ethernet interface through the computer’s USB-C connection. A compatible 2.5 GbE network can provide more link capacity than a Gigabit connection. Actual speed depends on the host, network equipment, cabling and service. Keep the Charger in the Setup USB-C Power Delivery support up to 100 W allows a suitable charger to form part of the connection. The laptop and charger negotiate power, and the adapter also uses power. Verify host charging support and use an appropriately rated USB-C PD charger and cable. Match the Available Link Automatically The adapter detects supported 10/100/1000/2500 Mbps Ethernet speeds and handles crossover detection automatically. This lets it join compatible networks without requiring a fixed manual speed setting. The link will operate within the limits of the connected port and cable. See the Connection at a Glance Two indicators distinguish connection from link activity. They provide a convenient first check when moving between desks or reconnecting a cable. Indicators help identify link state; they do not by themselves verify internet access or application performance. Portable and Powered by USB The 33 g enclosure measures 80 × 25 × 15 mm and has an integrated 18 cm host cable. It draws operating power from USB rather than requiring a dedicated adapter supply. Hot-pluggable operation makes it useful for a compatible computer that moves between wired and wireless workspaces. Useful Ethernet Standards Support includes flow control, energy-efficient Ethernet and documented VLAN tagging/priority standards. These features operate within a compatible host driver and network configuration. The adapter is a network interface rather than a managed switch or router. Summary D-Link DUB-E255 USB-C to 2.5 GbE Ethernet Adapter with Power Delivery combines multi-Gigabit Ethernet and USB-C charging capability in one portable adapter. Match the host, network and PD equipment to the documented functions for a straightforward wired workspace. Frequently Asked Questions Will It Make My Internet Connection Faster?ExpandCollapse The maximum Ethernet link is 2.5 Gbps. Internet speed remains limited by your broadband service, router, network path, computer and cabling. It cannot turn a slower service into a 2.5 Gbps internet connection. Will It Charge My Laptop at the Full Rated Power?ExpandCollapse The 100 W rating is the hub's maximum USB-C Power Delivery capability. Charging depends on the connected charger, cable and laptop, and available power is shared with the hub. Use a suitable USB-C PD charger and cable; neither a charger nor a charging cable is implied to be included. Can I Use It with a Slower Ethernet Port?ExpandCollapse Yes. Automatic speed detection supports 10/100/1000/2500 Mbps. The link negotiates a rate supported by both ends and the cable. Does It Work with a Thunderbolt Port?ExpandCollapse The manufacturer specifies a USB-C host connector compatible with Thunderbolt 3/4 hosts. The computer must support the required USB data and, if used, USB-C charging functions. Which Computers Are Supported?ExpandCollapse The local datasheet lists Windows, macOS and Nintendo Switch compatibility. Check the operating-system driver and device support for your exact host; the same connector shape does not guarantee every platform function. What Warranty Is Included?ExpandCollapse The hardware warranty is 1 year. Network cables, USB-C PD chargers and charging cables are separate accessories. 続きを読む
