The UARTs interface available * J8 is a 20x2x2.54mm pin header expansion connector that delivers many interfaces unused on the Evaluation Kit at the board. On this connector ''TBDare mapped these instances:Jxxx''UART1; UART2 (default debug console); UART4.

''Jxx'' is a ''TBD[[File:connectorORCA-EVK-J8-type'' header connector for the RS232 two-wires UART3 port, used for debug purposes (bootloader and operating system serial console).png|thumb|center|500px|UARTs J8 connector]]

UART3 UART1 is mapped to <code>/dev/ttymxc0</code> device in Linux UART2 is mapped to <code>/dev/ttymxc2ttymxc1</code> device in Linux. The peripheral is used as the default serial console, both for the bootloader and the kernel. UART3 is mapped to <code>/dev/ttymxc2</code> device in Linux UART4 is mapped to <code>/dev/ttymxc3</code> device in Linux

To connect The TTL UARTs on J8 can be connected to the debug serial port:external devices that use 0-3.3V levels.

# connect the DB9 adapter bracket to the J22 connector on The RS232 and RS485 uses the SBCX board# connect a serial cable between DB9 connector and PC COM port through a NULL-modem cable (not provided)# start your favorite terminal emulator software on PC (eg: PuTTY); communication parameters are: 115200,N,8,1standard protocols.
