USB-UART converters are integrated circuits that enable efficient and undisturbed communication. They are designed to exchange information, which is possible due to asymmetric transmission. Data is received through the serial port. Functioning of the USB-UART converters starts with a start bit, which has the form of logical zero. In subsequent stages 7,8 and 9 bits are transferred. However, the number of bits depends on the configuration of the device. The information ends with the stop bit, which is always the only logical one. The whole information is called a UART frame.

USB - UART / RS232 / RS485 converters - FAQ
( UART ) is a hardware device for asynchronous serial communication - an electronic integrated circuit. Data format and baud rate are configurable. UART sends data bits one by one, from least significant to most significant, so that the communication channel supports precise timing.
RS-232 is an interface for exchanging serial binary data between two devices. It is a standard protocol used for serial communication: it is used to connect a computer and its peripheral devices to enable serial data exchange.
RS-485 is usually an interface for industrial applications. The RS-485 standard allows long cabling distances in environments with high levels of electrical noise and can support multiple devices on the same bus without interference, which is extremely important when dealing with a large number of different devices.
