XBee / XBee-PRO RF Modules 802.15.4 Product Manual 24
Applicable commands: IA (I/O Input Address), TN (Dn Output Timeout), P0 (PWM0 Configuration),
P1 (PWM1 Configuration), M0 (PWM0 Output Level), M1 (PWM1 Output Level), PT (PWM Output
Timeout), RP (RSSSI PWM Timer)
Configuration example
As an example for a simple A/D link, a pair of RF modules could be set as follows:
These settings configure the remote module to sample AD0 and AD1 once each every 20 ms. It then
buffers 5 samples each before sending them back to the base module. The base should then receive
a 32-byte transmission (20 bytes data and 12 bytes framing) every 100 ms.
XBee / XBee-PRO networks
The following terms are used to explain the network operations:
Peer-to-peer
By default, XBee / XBee-PRO RF Modules are configured to operate within a Peer-to-peer network
topology and therefore are not dependent upon Master/Slave relationships. NonBeacon systems
operate within a Peer-to-peer network topology and therefore are not dependent upon Master/Slave
relationships. This means that modules remain synchronized without use of master/server
configurations and each module in the network shares both roles of master and slave. Digi's peer-to-
peer architecture features fast synchronization times and fast cold start times. This default
configuration accommodates a wide range of RF data applications.
Remote Configuration
DL = 0x1234
MY = 0x5678
D0 = 2
D1 = 2
IR = 0x14
IT = 5
Base Configuration
DL = 0x5678
MY = 0x1234
P0 = 2
P1 = 2
IU = 1
IA = 0x5678 (or 0xFFFF)
Table 7: Terms and definitions
Term Definition
PAN Personal Area Network - A data communication network that includes one or more End Devices
and optionally a Coordinator.
Coordinator A Full-function device (FFD) that provides network synchronization by polling nodes
[NonBeacon (with Coordinator) networks only].
End Device When in the same network as a Coordinator - RF modules that rely on a Coordinator for
synchronization and can be put into states of sleep for low-power applications.
Association The establishment of membership between End Devices and a Coordinator. Association is only
applicable in NonBeacon (with Coordinator) networks.
