General Description
The D-Link DFE-680TXD 10/100 Ethernet PC Card for CardBus notebook PCs is a
credit-card sized Ethernet / Fast-Ethernet adapter for connecting a notebook PC to an
IEEE 802.3 or 802.3u Ethernet network. The notebook PC must be equipped with

The DFE-680TXD automatically detects the parameters of its Ethernet environment, and
automatically negotiates and determines its own speed and duplex settings as required fo r
maximum performance within the environment. (The autonegotiation function is
effective only when the DFE-680TXD is connected to the network by a device (switch or
hub) which also has autonegotiation functionality.)
