6.0. RS-232 Communication Interface
RS-232 serial communication is performed through a 9-pin SUB-D connector and the microcontroller USART module. In order to enable
such communication, it is necessary to establish a connection between RX and TX communication lines (
RTS are optionally used) and microcontroller pins provided with USART module using a DIP switch. The microcontroller pins used in such
communication are marked as follows: RX -
goes up to 115kbps.
The USART (universal synchronous/asynchronous receiver/transmitter) is one of the most common ways of exchanging data between the
PC and peripheral components. In order to enable the USART module of the microcontroller to receive input signals with different voltage
levels, it is necessary to provide a voltage level converter such as MAX-202C.
The function of DIP switches SW7 and SW8 is to determine which of the microcontroller pins are to be used as RX and TX lines. The
microcontroller pinout varies depending on the type of the microcontroller. Figure 6-2 shows the microcontroller in DIP40 package
(PIC16F887).

Make sure that your microcontroller is provided with the USART module as it is not necessarily integrated in all microcontrollers.
