2.1.3 Transmit and Receive Connections(J11 and J22)

All transmit and receive (TXD and RXD) for both CAN interfaces, VIO, VCC, and GND connections are available on the J11 and J22 header. This allows the user the ability to evaluate the communication parameters of the transceiver in a straightforward manner.

This header is 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 a single cable with all power and signals via a 10-pin header cable to this port.
