Introduction
This chapter describes the Fast EtherWORKS/PMC Adapter module
and summarizes its features. This chapter also describes the module’s
connector and LEDs.
Fast EtherWORKS/PMC Adapter is a PCI Mezzanine Card (PMC)
with a direct interface to the 32-bit PCI local bus. This dual-speed
module uses a single connector for either a 10 megabits per second
(10-Mb/s) or a 100 megabits per second (100-Mb/s) IEEE 802.3
Ethernet network connection. The module automatically senses
and switches to the correct speed. For information about the Fast
Ethernet technology, see Appendix C.
The DE520 Adapter is available in three versions:
• DE520-AA, PMC with an unshielded Adapter Cable
• DE520-AB, PMC with P14 Connector I/O
• DE520-AC, PMC with a shielded Adapter Cable
Features
The Fast EtherWORKS/PMC Adapter module has the following
features:
• High performance: full-speed, 32-bit DMA bus transfers at
132 MB/s
• Single-shielded or unshielded RJ-45 connection: AA variant uses
unshielded cables and the AC variant uses shielded cables
• Automatic sensing of speed and change to that speed
