2. RF Module Operation
Serial Communications
UART Data Flow
Serial Data
The XBee®/XBee-PRO® RF Modules interface to a host device through a logic-level asynchronous
serial port. Through its serial port, the module can communicate with any logic and voltage com-
patible UART; or through a level translator to any serial device (For example: Through a Digi pro-
prietary RS-232 or USB interface board).
Devices that have a UART interface can connect directly to the pins of the RF module as shown in
the figure below.
Figure 2‐01. System Data Flow Diagram in a UART‐interfaced environment
Data enters the module UART through the DI pin (pin 3) as an asynchronous serial signal. The sig-
nal should idle high when no data is being transmitted.
Each data byte consists of a start bit (low), 8 data bits (least significant bit first) and a stop bit
(high). The following figure illustrates the serial bit pattern of data passing through the module.

Serial communications depend on the two UARTs (the microcontroller's and the RF module's) to be
configured with compatible settings (baud rate, parity, start bits, stop bits, data bits).
The UART baud rate and parity settings on the XBee module can be configured with the BD and SB
commands, respectively. See the command table in Chapter 3 for details.
