Diagnostic Interface RS232C

The signals TX0 and RX0 are transmit and receive signals to use with an RS232C interface for di-
agnostic purpose.

Over this diagnostic line you can download a new firmware, configuration files or make only diag-
nostic during running communication.

The following schematic shows an example for the RS232C interface necessary on the host board.
The module has not integrated drivers.
