11.4 UART/RS-232 Interface (Option R&S RTM-K2)

11.4.1 The UART / RS232 Interface

The Universal Asynchronous Receiver/Transmitter UART converts a word of data into
serial data, and vice versa. It is the base of many serial protocols like of RS-232. The
UART uses only one line, or two lines for transmitter and receiver.

Data transfer

The data is transmitted in symbols, also referred to as words or characters. Each symbol
consists of a start bit, several data bits, an optional parity bit, and one or more stop bits.
Several symbols can form a frame, or package. The end of a frame is marked by a pause
between two symbols.

[Data8] [Parity] Stop

Fig. 11-9: Bit order in a UART word (symbol)

●

The start bit is a logic 0.

●

The stop bits and the idle state are always logic 1.
