4. RS-232 module
The RS-232 module enables the development system to communicate with external devices whose operation
is in compliance with the RS-232 standard. In order to establish connection between the RS-232 module and the
microcontroller, it is necessary to set switches 1 and 2 (optionally 3 and 4) on the DIP switch SW2 to the ON position.
