Introduction

The D-Link DFE-538TX is ideal for the small office or home office environment.

After completing the steps in this manual, you will have the ability to share

information and resources - such as files and printers - and take full advantage of a

"connected" environment for work and play!

The DFE-538TX comes with drivers for the most popular operating systems and

can be integrated into a larger network. However, this Guide is designed to help

you network two computers running Windows 95/98, Me, 2000, XP and 2003 ina

peer-to-peer configuration. Yet,the standards compliant DFE-538TX gives you the

flexibility to expand and customize your Ethernet / Fast Ethernet network at will.

The Ethernet standard allows you to connect computers and devices at speeds up to

10 Mbps. Fast Ethernet allows speeds up to 100 Mbps. A Dual-Speed 10/100 Mbps

Ethernet / Fast Ethernet network combines both standards allowing computers and

devices of different speeds to communicate with each other. The DFE-538TX is a

Dual-Speed 10/100 Mbps Ethernet / Fast Ethernet network card.

Technology Basics

About Fast Ethernet

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

extends the traditional 10Mbps Ethernet technology to achieve 100Mbps

transmission and reception, while retaining the same CSMA/CD Ethernet protocol.

Thus, while Fast Ethernet provides a tenfold increase in network capacity, it is

wholly compatible with traditional 10Mbps Ethernet network facilities. This

compatibility is the key to easy and efficient upgrades to 100Mbps in your network

areas needing greater bandwidth. Upgrading selected areas to Fast Ethernet does

not require hardware or software changes in network areas where traditional

10Mbps Ethernet is providing good service. For upgrading, Fast Ethernet is the

clear choice in terms of cost-effectiveness, as well as convenience and smoothness

in transition.

Category 5 cabling is required for 100Base-TX Fast Ethernet in order to provide full

duplex operation. Full duplex 100Base-TX operation allows simultaneous

transmission and reception, both at 100Mbps, thus providing service potentially

equal to 200Mbps full-duplex service.

To provide compatibility in traditional 10Mbps Ethernet environments (where, for

example, DFE-538TX adapters are installed anticipating upgrade of supporting

switch equipment to Fast Ethernet), the DFE-538TX also supports traditional

10Mbps Ethernet operation, in full-duplex as well as half-duplex modes. Selection

of the best operation mode in any given installation is automatically governed by

auto-negotiation.

About Auto-Negotiation

You have probably had the experience of making a dialup connection through a

modem, and have heard the sound exchange between your modem and the modem

at the other end of the telephone line. 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.

When the two modems have tested the phone-line quality and settled on the

combination of shared options and parameters which will provide the best data

communication over the connecting phone line, then you are given the “connect”

message which signals the end of the intermodem negotiation and the beginning of

your intended communication with the remote computer.

Auto-negotiation between devices within an Ethernet LAN is similar in concept, but

much briefer. The two devices involved in the auto-negotiation will be the DFE-

538TX Adapter serving your station (installed in your computer), and the switch

through which it is connected to the LAN. The options to be negotiated between

the DFE-538TX and its supporting switch includes Ethernet type (100BASE-TX

Fast Ethernet or 10BASE-T Ethernet) and duplex mode (half-duplex, being one-

way-at-a-time, or full duplex, being simultaneous transmit-and receive.)

Startup communication between the two devices occurs when both devices

are powered up. Once the cable connection and the Network Operating

System software is satisfied, the preparatory process of auto-negotiation

between the DFE-538TX and its supporting switch proceeds automatically. If

the switch has auto-negotiation functionality, it and the DFE-538TX exchange

a series of messages, 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.

If the switch does not support auto-negotiation, the (single capability)

message will be recognized by the DFE-538TX auto-negotiation facility,

which will switch to those settings of its own capabilities, which match that of

the switch.

Auto-negotiation reoccurs any time the linkage is restored, making the line

ready again for optimal data communications.

About PCI Bus

Your DFE-538TX Adapter delivers outstanding performance by fully

exploiting the advance features of your computer’s PCI bus. DFE-538TX

Adapters utilize the Bus Master Mode of the PCI bus, allowing direct

transfers of Ethernet packet content between computer memory and the

adapter’s controller, thus minimizing network demands on the CPU. The

adapter’s controller function provides the additional benefit of reduced

command processing overhead.

The working relationship between a DFE-538TX adapter and main memory

working in Bus Master mode is powered by the Bridge/Memory Controller of

the PCI bus. This reduces the CPU role in network operations, thus freeing

the CPU to service other tasks, with resulting improvement in overall

computing (multitasking) performance. At the same time, it produces

superior network throughput by reducing latency (waiting for CPU service)

during transmissions and receptions.

Features

Wake On LAN

Wake On LAN (WOL) is an ACPI function allowing a powered down (sleeping)

computer to be powered ON from a remote station. To use the WOL feature, the

NIC must be WOL capable and the motherboard of the PC must be ACPI compliant.

While powered-down computers Sleep, WOL enabled NICs monitor LAN traffic

for valid Wake-up frames. When one is received, the NIC will immediately wake-

up and send a signal to the motherboard to power ON the computer.

Some uses for the WOL feature include:

• Forgot a document and are out of town? Send a Wake-up signal to your

computer and retrieve the needed file.

• Initiate long routines and reports before you get to work.

• Transfer files when the network traffic is low (during late hours).

• Power ON your PC before you arrive to work.

• The MIS department can upgrade software on computers after hours from a

remote station.

Connecting the WOL Cable

NOTE: If your system’s motherboard WOL Connector does not fit the WOL

Cable or does not have 3 pins, do not attempt to force a connection or alter the

components to fit. Doing so could permanently damage your computer.

The WOL function is system dependent, in addition to the following instructions,

you may need to download WOL software from INTEL or another

manufacturer’s website.

Please consult your computer’s manual for specific BIOS settings.

The WOL Cable is an interconnect cable with standard 3-pin connectors on each

end. Please follow the procedures listed below to ensure proper installation of the

WOL cable.

1. Connect either end connector of the WOL Cable to the NIC WOL

Connector. Both ends of the WOL Cable are identical, so either end may be

used.

2. Examine the PC motherboard and/or refer to the manual for the

motherboard to locate the corresponding WOL Connector on the

motherboard. The actual location is system dependent, but the motherboard

may have a label beside the WOL Connector. After you have located the

WOL connector on the motherboard, connect the cable.

3. Power-ON the PC and press “Delete” or “F1” when prompted to enter the

PCI/ISA BIOS CMOS Setup. Enable the WOL function or the power-ON

function of the PC. The name of this function is system dependent, but may

be located in a category heading titled something like Power Management.

Refer to your computer’s manual for more information regarding the

CMOS Setup Utility and BIOS settings.

Flow Control

The DFE-538TX implements IEEE 802.3x compliant flow control for full duplex,

which provides traffic management functions for full-duplex operation. Flow

control allows for enhanced full duplex operation with switches. When operating at

full duplex (requiring a direct connection to a switch) and the switch’s data buffer is

about to overflow, a Pause frame will be transmitted to the DFE-538TX. The

ensuing idle time keeps the buffer from overflowing and prevents data from being

lost. This enhancement can improve network throughput, avoid collisions and

prevent lost data, helping the network achieve optimal performance.
