D-Link's DFE-538TX Fast Ethernet adapter is a high-performance NWay 10/100Mbps adapter for the PCI bus that supports Wake-on-LAN. It turns a desktop into a high-bandwidth graphic/multimedia work-station or a power server running at full-duplex speed. The adapter operates in the 32-bit Bus Master mode, delivering throughputs at multi-megabits per second with little stress on the host's CPU. Supporting PCI clock speeds independently of the network clock, it transfers data directly to/from the host's memory, by-passing the CPU to alleviate the host's workload. The adapter's dual-speed interface allows users to migrate from Ethernet to Fast Ethernet in easy steps. 10BASE-T users can upgrade to 100BASE-TX anytime without changing driver software or network cables.The adapter's single connector connects to either 10BASE-T Ethernet or 100BASE-TX Fast Ethernet completely without any need to set configuration. It detects the connected hub's or switch's capability and auto-negotiates to use the highest available speed. Wake-on-LAN (WOL) is an advanced Configuration Power Interface (ACPI) function allowing a powered OFF computer to be powered ON from a remote station. This function allows the user to send a wake-up signal to a computer. The WOL function provides a great utility for power management of PC and allows users to initiate action at irregular times and from distant locations. Full/Half duplex operation is auto-detected in both 10BASE-T and 100BASE-TX modes. When connected to a switch in full duplex, the network speed can be increased to 20/200Mbps, making the adapter an ideal NIC for high-speed server deployment.
