Rev.01 (August, 1997) 6DFE853...01 Printed in TaiwanThis guide provides basic information for installation and use of D-Link Fast Ethernet transceiver models DFE-853 and DFE-854. Introduction D-Link Fast Ethernet transceiver models DFE-853 and DFE-854 represent the best value on the market. These transceivers are IEEE 802.3u compliant and support both half- and full-duplex operation. Diagnostic LEDs are on the front, with the cabling connectors, for maximum visibility. Transceivers provide additional media options for Fast Ethernet hubs, switches, bridges and routers equipped with MII ports. A DFE-853/DFE-854 transceiver is recommended for a network device with a built-in MII connector. The DFE-853 MII to 10BASE-T or 100BASE-TX transceiver has the Auto-negotiation function, which means the transceiver automatically adjusts itself to the Ethernet speed (10 or 100) and duplex mode (half or full) of the attached segment. When two autonegotiation devices with multiple capabilities are linked together, they find their optimum common mode of operation.
