Product Overview

The D-Link® HD MediaBridge® Coax Network Starter Kit (DXN-221) is a simple solution for enabling network access by utilizing your home’s existing coaxial (cable) wiring. The HD MediaBridge kit includes two HD MediaBridge Coax Network Adapters (DXN-220), each with an Ethernet port and a coaxial connector to easily connect to available coaxial outlets*.

The HD MediaBridge Coax Adapter is a Coax-to-Ethernet bridge and comes with one Coax F-type connector and one Ethernet RJ-45 connector. Simply connect one HD MediaBridge Coax Adapter to a router using the provided Ethernet cable to establish a network connection and to an available coaxial outlet in the room to access your home’s coaxial wiring. Then add the second HD MediaBridge Coax Adapter in another room to connect a PC or other Ethernet-ready device (such as Game Consoles, Media Players, Blu-ray Disc Players, etc.) to the network.

For rooms with multiple Ethernet-devices, simply connect a switch to the HD MediaBridge Coax Adapter to network additional devices. If your router has Internet access, then all devices connected using the HD MediaBridge Coax Adapter can share Internet access as well. Additional HD MediaBridge Coax Adapters can be added to bridge additional rooms.
