4.1.7. X9 DSUB-9 female
Pin-header X9 is a DSUB-connector in RS232/RS485/RS422 levels. It corresponds to
USART0 of the AT91SAMA5D3x. The driver chip can be switched between the different
modes. Drive PC17/TF0 high for RS485 mode and low for RS232 mode. Drive PC18/TD0
high for half-duplex mode and low for full duplex. Dip switch S1 also influences the level
of these configuration lines. Refer to the schematics AppendixF, PanelA5 Schematics for
details. RI can be powered by 5V by setting jumper J10 (default unset).
