From the ManufacturerThe DFE-670TXD provides instant connectivity for mobile users, enabling easy access to networks. With the D-Link DFE-670TXD, users can access databases and resources in diverse environments with ease and fast connectivity.The DFE-670TXD adheres to IEEE 802.3 and IEEE 802.3u standards, which specify existing 10BASE-T and 100BASE-TX Ethernet technology. This supports both half and full duplex modes with data rates up to 10/100Mbps and 20/200Mbps. The DFE-670TXD also utilizes auto-negotiation to adjust the speed to any 10BASE-T or 100BASE-TX network automatically. With these features, the DFE-670TXD is an excellent choice for mobile users.With the DFE-670TXD's RAM data buffer, all incoming data is processed and stored into temporary memory and, then, eventually filtered out. This capability results in smooth data flow. For easy monitorying, the DFE-670TXD's extensive diagnostic LEDs show link connectivity for both 10Link/Activity and 100Link/Activity.Designed with a plug-and-play feature, the DFE-670TXD is simple to install and operate. With built-in hot swapping capabilites, the DFE-670TXD can be removed while the computer is still in operation.
