Ethernet Interface (J5)

The VL-EPM-24 features an on-board Intel 82574IT gigabit Ethernet controller, which provides
a standard IEEE 802.3 Ethernet interface for 1000Base-T, 100Base-T, 100Base-TX, and 10Base-
T applications. The 82574IT consumes one PCIe lane operating at 2.5 Mbps with sufficient
bandwidth to support a 1000 Mbps transfer rate.

THERNET ONNECTOR
A board-mounted RJ45 connector is provided to make connection with a Category 5 or 6
Ethernet cable. The 82574IT Ethernet controller auto-negotiates connection speed. The interface
uses IEC 61000-4-2-rated TVS components to help protect against ESD damage.
