Board Interfaces
The following sections provide detailed information regarding the connector layout and pinout
of the various board interfaces of the EBC2. The section ordering is by the connector designa-
tor.
2.4.1
J1 - Dual Giga Ethernet Connector
This connector provides interfacing for E²Brain™ modules which support the three speed Eth-
ernet channels TSE1 and TSE2. This is a dual RJ45 connector with LEDs to indicate the status
of the links.
