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
CardBus (32 bit) extension bus and Type II or Type III PC Card slot (s).
NOTE: The terms "PC Card" and “CardBus” are used throughout this manual to refer to
those objects as defined in the PCMCIA / PC Card standards published by Personal
Computer Memory Card Industry Association (PCMCIA). The term “slot” is used in this
manual is synonymous with “socket” where the standards use the latter term in reference
to the physical receptacles of a host notebook computer, for insertion/connection of PC
Cards. More information on the standards is available from PCMCIA’s www server at
http://www.pc-card.com.
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.)
Inside its compact case, the D-Link DFE-680TXD holds an Ethernet controller, network
processing interface, a 68-pin PC Card Standard front -end plug, which connects to the
notebook PC, and a direct port for connecting RJ-45. The DFE-680TXD requires no pre-
installation setup -- simply insert its front end into the notebook PC's PC-Card slot.
The DFE-680TXD is supplied with an RJ-45 receptacle, which receives the network
cable. The direct port features full LED display for linkage and activity states, and for the
