expansion adapter card for systems adhering to the Peripheral Component Interconnect
(PCI) and IEEE 802.3 standards. The adapter connects the system to an Ethernet LAN
at either 10Mbps or 100Mbps data rate.
The 4-Port 10/100 Base-TX Ethernet PCI Adapter provides the following features:
v Easy installation and automatic configuration
v PCI bus master, 32/64-bit, 33MHz
v PCI Universal connector to accommodate +5 Volt and +3 Volt signaling
v 2 LED adapter status indicators per each port
v Auto negotiation of 10Mbps or 100Mbps
v Half-duplex or full-duplex operation
v 64KB on-card FIFO for transmit and receive per port
v 4 RJ-45 connectors for UTP or STP cabling
v Ball Grid Array (BGA), surface mount (SMT) and pin-in-hole (PIH) technology.
