UART 0 is available at the 9-pin Sub-D female connector X800 with RS-232 inputs and outputs.
UART 1 is available at the 9-pin Sub-D female connector X801 with RS-232 inputs and outputs.
As transceiver with enhanced electrostatic discharge ( ESD ) protection the MAX3243EIPW
( U800, U801 ) are used.
Following table shows the assignment of pins, signals and function from the UART connector
X800. Connector X801 is identical. For X801 the index 0 has to be changed to 1.
Pin Signal Function
1 RS232_0_CD Data carrier detect
2 RS232_0_TXD Transmit data
3 RS232_0_RXD Receive data
4 RS232_0_DSR Data set ready
5 GND Ground
6 RS232_0_DTR Data terminal ready
