8.0. RS-232 modules
The RS-232 modules enable the development system to communicate to external devices whose operation is in
compliance with the RS-232 standard. The BIG8051 development system features two RS-232 modules that operate
independently. To connect the RS-232A module and the microcontroller, switches 1 and 3 (optionally 2 and 4) on the
DIP switch SW11 should be set to the ON position. Similarly, to connect the RS-232B module and the microcontroller,
switches 5 and 7 (optionally 6 and 8) on the DIP switch SW11 should be set to the ON position.
