Connecting RS232 Devices
If you use the UART interface as an RS232 transceiver, you have to
cross-connect the TXD and RXD signals for connecting external
devices.
To do this, connect the pin of the TXD (output) signal to the pin of the
RXD (input) signal as shown below.
N
For some devices (e.g., modems), you should not cross-connect the
TXD and RXD signals. For the correct connection refer to the manual
of the device you want to connect to the DS1104.
