Ethernet Interface
The EPM-CPU-10 features an industry-standard 10baseT / 100baseTX Ethernet interface based
on the Intel 82559ER interface chip. While this interface is not NE2000 compatible, the 82559ER
series is widely supported. Drivers are readily available to support a variety of operating systems
such as QNX, VxWorks and other RTOS vendors.

Ethernet Status
LED D2 provides an onboard indication of the current condition of the board’s Ethernet
functionality.
Yellow = 10/100
Off = 10 Base T
On = 100 Base T
Green = Link/Activity
On = (solid) Link
Off = (Flickers) Blinks Activity
