Fast EtherWORKS/PMC Adapter

This document serves as the user manual for the Fast EtherWORKS/PMC Adapter module (part number DE520-AA), a high-performance network interface card (NIC) designed for the 32-bit PCI bus. The adapter is a dual-speed (10 Mb/s and 100 Mb/s) IEEE 802.3 Ethernet PCI Mezzanine Card (PMC), featuring automatic speed sensing, full-duplex operation (up to 200 Mb/s), and a parallel cut-through architecture for maximized data throughput and minimal CPU usage. It supports both 10BASE-T (Category 3, 4, or 5 UTP) and 100BASE-TX (Category 5 UTP) cabling via a single RJ-45 connector. The module complies with PCI revision 2.0+, FCC Class A, and CISPR-22 Class A, and includes a lifetime warranty.

The manual provides detailed instructions for installation, covering system preparation, physical module insertion, and connecting to the network, with emphasis on static electricity precautions and power supply considerations. Operational status is indicated by three LEDs: a 100 Mb/s status LED, an Activity status LED for data transmission/reception, and a Link status LED for network connection. Troubleshooting guidance for network connection faults is provided, along with methods for verifying network operation using TCP/IP services.

General technical specifications, such as physical dimensions, power requirements, operating environment, and RJ-45 pin assignments, are also detailed. An appendix explains Fast Ethernet technology as a standards-based, cost-effective solution for high-performance LANs, enabling seamless migration from 10BASE-T by leveraging existing infrastructure. The document concludes with international technical support contact information and descriptions of other Digital network adapter products.
