=== UART2 /CAN - J5 ===
J5 is a standard DB9 '''male''' connector for the configurable UART/CAN port. The board provides some '''hardware''' mount options for the selection of the UART mode (RS232/RS422/RS485 with autodirectionauto-direction) or the CAN mode. The board default configuration provides the CAN interface on this port, while the RS232/RS422/RS485 interface is provided as an option to customers who choose the alternative configuration. The following table reports the connector's pinout:
