Abaco Systems / Ramix PMC610 Quad 10/100BaseTX Ethernet NIC PMC, Front I/O Module

The Abaco Systems PMC610 is a PCI Mezzanine Card (PMC) that delivers quad 10/100BaseTX Ethernet connectivity for embedded and real-time systems. Four independent 10/100 Mbit/s ports with front-panel RJ45 connectors enable direct network integration without backplane routing constraints. The card employs a PCI-to-PCI bridge, powerful DMA engines, and deep FIFO buffers to achieve full-bandwidth operation with minimal PCI overhead.

Compliant with IEEE 802.3u, it auto-negotiates speed and duplex settings, supporting full-duplex 10 and 100 Mbit modes. TCP/UDP checksum offloading and IP Security (IPSec) acceleration further optimize network performance.
