Data Formats and Baud Rates
The default baud rate and data format is 9600 baud, 8 data bits, no parity and one stop bit. The baud
rate and data format can be adjusted by adjusting the BD and NB parameter of the radio module (See
the Changing the Baud Rate section). If the data of the sending or receiving devices do not correspond
with the data settings of the Wireless Bridge then the output data will appear garbled.
Common Configurations and Use Cases
Radio Architectures
Point-to Point
Fig. 4 Typical RS-232 Point-to-Point Configuration
The most basic architecture is point-to-point. In this mode, one Wireless Bridge Device communicates
with a second Wireless Bridge Device. If more than one pair of radios are within range of each other,
then certain addressing commands should be set within the on board Digi XBee radio to isolate the
individual pairs. The commands that control addressing are:
ID – Controls the network identification number.
CH- Controls the channel (frequency) of the device.
DH & DL – Sets the destination address. For point-to-point mode DH & DL on Radio A should be set to
the SH & SL values of Radio B and vice versa.
See the XBee S2C manual and X-CTU program for complete details.
