ONNECTOR

Connector JS5 includes an interface to the Ethernet controller. The 82551ER Ethernet controller
autodetects 10BaseT/100Base-TX connectors. The Ethernet port uses IEC 61000-4-2-rated TVS
components to help protect against ESD damage.

The CBR-8001 breakout cable provides an RJ-45 connector to make connections with Category 5
Ethernet cables.
