Introduction

Thank you for choosing D-Link DFE-680TXD, the value leader among Ethernet / Fast

Ethernet adapters for CardBus notebook PCs. This chapter provides a general description

of DFE-680TXD features, with a summary of features at the end of the chapter.

Installation instructions are given in Chapters 2 and 3.

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

speed and duplex ,and for transmitting and receiving data and carrier detection.

About Fast Ethernet

Fast Ethernet is a network technology specified by IEEE Standard 802.3u. It extends the

traditional 10Mbps (10 megabit/sec) Ethernet technology to achieve 100Mbps (100

megabit/sec) transmission and reception. Because Fast Ethernet retains the traditional

Ethernet CSMA/CD (Carrier Sense, Multiple Access, Collision Detect) protocol, it

remains wholly compatible with 10Mbps Ethernet while providing a tenfold increase in

network capacity.

The Fast Ethernet standard specifies three subtypes, corresponding to three media types:

•100Base-TX (using two twisted pairs in EIA 568 Category 5 UTP or STP cable)

•100Base-T4 (using four twisted pairs in a Category 3, Category 4, or Category 5

UTP cable) 100Base-FX (using two fiber-optic strands).

The DFE-680TXD provides full-duplex and half-duplex 100Base-TX operation (in

Category 5 twisted-pair cable environments). It does not provide 100Base-T4 or

100Base-FX operation. To provide for traditional 10Mbps Ethernet operation in twisted-

pair cable environments, the DFE-680TXD also offers 10Mbps Ethernet operation, in

full-duplex and half-duplex modes. The DFE-680TXD's autonegotiation capability

provides for automatic selection of the best operation mode.

About Autonegotiation

The basic idea of auto-negotiation can be understood by reflecting for a moment on the

familiar process of making a dialup connection between two modems. You have probably

heard some gravelly−sounding exchanges between your local modem and a modem at the

other end of a telephone line. (These exchanges are ordinarily played out through a

speaker in your local modem). As irritating as those few seconds of noise may be, they do

let you know that your modem and the remote modem are on the job, preparing for your

intended communication with the remote computer.

The preparatory work of the two modems during those few seconds before you see the

“connect” message is to negotiate the best data communication scheme which is

supported by both modems, and which is suitable for the quality of the telephone-line

connection between them. The parameters to be settled between the two modems include

best baud rate, compression method, and error correction method. When the two modems

have tested the phone-line quality and have switched to the combination of parameters

which will provide the best data communication, then you are given the “ connect”

message which signals the end of the inter-modem negotiation and the beginning of your

intended communication with the remote computer.

Autonegotiation between devices within an Ethernet LAN is similar in concept, but much

briefer. The two devices involved in the autonegotiation will be your DFE-680TXD and

the switch or hub through which it is connected into the LAN. (Switches ordinarily

provide for autonegotiation; traditional hubs do not.) The parameters to be negotiated

between the DFE-680TXD and its supporting switch or hub include speed (100Mbps =

Fast Ethernet, or 10Mbps = traditional Ethernet) and duplex mode (half-duplex or full-

duplex).

Startup communication between the two devices occurs when both devices are operating,

the cable connection between them is good, and the connected notebook PC's network

software is loaded. As soon as those conditions are satisfied, the preparatory process of

auto-negotiation between the DFE-680TXD and its supporting device begins and

proceeds automatically.

If the supporting switch or hub has autonegotiation functionality, then it and the DFE-

680TXD exchange a series of messages in which each device signals its capabilities and

listens for corresponding information about the other. The auto-negotiation process

requires only a few milliseconds, and the two devices select the best communication

parameters supported by both devices.

If the supporting device does not have autonegotiation functionality, then its monotone

(single capability) message will be recognized by the DFE-680TXD’s autonegotiation

facility, and the DFE-680TXD will simply switch to the one of its own capabilities which

matches that of the supporting device.

Once the auto-negotiation is completed, then the line is ready, and it will provide an

optimal data channel between the DFE-680TXD and the supporting device. The line will

remain ready without further auto-negotiation action until the linkage is broken. Auto-

negotiation then reoccurs at any time that the linkage is restored, again making the line

ready for optimal data communications.

LED Indicators

The direct port features six LED indicators:

10/100 Indicator: Solid LED clearly indicates when you are connected to a Fast Ethernet

Network.

Half /Full Indicator:

Steady green indicates Full-Duplex selected.

Dark indicates Half-Duplex selected.

Ln/Act Indicator:

Steady green indicates that there is good linkage to the network ("Linkage" state,

quiescent). Flashing green indicates that the DFE-680TXD is transmitting or receiving

("Activity" state). In 10Mbps mode, flashing will be regular and periodic. In 100 Mbps

mode, flashing may be irregular, with longer dark periods during heavy traffic activity.

Rx Indicator:

Solid and Flashing LED clearly indicates when you are receiving data.

Tx Indicator:

Solid and Flashing LED clearly indicates when you are transmitting data.

CD Indicator:

Solid LED clearly indicates carrier detection.

In the event that any item is missing, or if you find any mismatch or damage, promptly

contact your dealer for an exchange.

Follow these four steps to install the DFE-680TXD:

Step 1: Insert the DFE-680TXD

Under the PC Card standard and the corresponding Japanese JEIDA standard, PC Cards

may safely be "hot swapped" –– it is not necessary to switch the computer's power off

before installing or removing the DFE-680TXD, or any other PC Card.

Find/select an open Type II or Type III PC Card slot on your notebook computer's side or

rear panel. Hold the DFE-680TXD with the colorful D-Link splash label upward. Insert

the front end of the PC Card into the CardBus slot, and slide the PC Card all the way into

the slot until it reaches a firm stop.

NOTE: Many notebook PCs feature a stacked pair of PC Card slots, logically (but not

physically) designated as Slot 1 and Slot 2.

It is most usual for the lower one of the two slots in the stack to be designated Slot 1, but

there are exceptions. In the subsequent procedure for DFE-680TXD software installation,

it might be useful for you to know whether your DFE-680TXD is installed in Slot 1 or

Slot 2. Under Windows 95, you can check by opening the Control Panel / PC Card

display. Under DOS it is also possible to make a software check, but it is more difficult.

If it develops that you need to make a trial-and-error determination or correction, then it

is easy to do: just reinstall the DFE-680TXD in another slot.

Step 2: Connect to the Network Medium

Make the network connection by running a UTP cable from the supporting switch or hub

to your direct port. Simply plug one end (RJ-45 plug) of the cable into an available port

of the switch or hub, and plug the other end (RJ-45 plug) into the RJ-45 socket of your

direct port coupler.

Step 3: Confirm Connection (Ln/Act Indicator)

When the notebook computer's power is ON, the DFE-680TXD is firmly seated in the

slot connector, the direct port has a good cable connection to the supporting hub, and the

supporting hub is power on and functioning properly, then the direct port’s Ln/Act LED

glows steady green ("Linkage" state).

If the Ln/Act LED remains dark without apparent cause, then the most likely fault is poor

engagement of the 68-pin front -end plug. Review the following section titled "Remove

the DFE-680TXD," then remove the DFE-680TXD from its slot. Repeat the procedures

of the above Step 1, "Insert the DFE-680TXD," taking care to ensure that the DFE-

680TXD is right side up and front-end first, and that it seats firmly in a suitable PC Card

slot of your notebook. Repeat the procedures of Steps 2 as necessary get the Ln/Act LED

confirmation.

NOTE: You might need to wait a few seconds following notebook power up, or

following insertion of a PC Card, for the software processing to be completed. The
