UART/RS-232 Debug Port

The conga-QMX6 is equipped with a six-pin RS232 connector onboard the conga-QMX6. This RS-232 debug port is connected to the NXP
i.MX6 UART1 and UART2 pins via the MAXIM-3232 transceiver. The transceiver is guaranteed to run at data rates of 250kbps in normal
operating mode, while maintaining RS-232 output levels.
Refer to section 5.2 for more information about the UART interface.
