Note:
The blue PiraT2 actively sends data on the “Tx” line if a protocol for the serial port is
configured. The “Tx” line must only be connected to special devices that support those
protocols. If the application is listening to a bidirectional serial communication of two
devices, two serial ports of the blue PiraT2 have to be used. The “Tx” lines must not be
connected in this case.
