2.1.1.2 I/O Headers (J2, J4)

All key I/O and supply GND functions are brought to headers J2 and J4. These headers can be used on either interface to test equipment or a short cable can be made to connect to an existing customer-application board with a CAN controller.

These headers are arranged to provide a separate ground for each signal pair (TXD/GND and RXD/GND). If the EVM is being used with lab equipment, connect separate cables to these main points via simple 2-pin header connectors. If connecting the board to a processor-based system, connect cables to all necessary signals to these headers.
