www .aerocomm.com T ERMS & D EFINITIONS 4 Ad-Hoc Network: A wireless network composed of communicating devices without preexisting infrastructure . Typically created in a spontaneous manner an d is self-organizing and self-ma intaining. Association: The process of joining a ZigBee PAN.
9 ZB2430 User’ s Manual - v1.6 T ERMS & DEFINITIONS www .aerocomm.com Maximu m Number of Chi ldren: The total number of children that can be associated with a single Network device. The current profile limit is 20; comprising of up to 6 Ro uters and 14 End Devices.
T ERMS & D EFINITI ONS 10 Route Request (RREQ): A ZigBee command used to discover paths through the network over which messages may be relayed. Routing Table: A table in which the Coordinator or Router(s) store information required to participate in the routing of data packets throughout the network.
www .aerocomm.com T HEORY OF O PERATION 5 IEEE 802.15.4 & ZI GBEE OVERVIEW The ZB2430 uses the ZigBee protocol stack, a netw ork layer protocol which uses small, l ow power digital transceivers based on the IEEE 802.15.4 hardware standard. The 802.
THEORY OF OPERATION 12 CREATING A NETWORK The IEEE 802.15.4 MAC provides support for two wireless network top ologies: star and mesh. The management of these networks is performed by the ZigBee layer. All device s, r egardless of topology, participate in t he network using their unique 16-bit address a ssigned by the Coordinator.
13 ZB2430 User’ s Manual - v1.6 THEORY OF OPERATION www .aerocomm.com Figure 1: ZigBee Network Topologies PARENT/CHILD RELATIONSHIP ZigBee uses a parent/child relationship between network de vices. The network begins with the Coor dinator as the first device on the network.
THEORY OF OPERATION 14 Figure 2: Parent/Child Relationship NETWORK LIMITATIONS The ZigBee network structure and ultimate size are specified by Stack profil es. The Stack profiles define the maximum number of Lay ers, maximum number of Children per Pare nt, & maximum number of Routers that can be Children.
15 ZB2430 User’ s Manual - v1.6 THEORY OF OPERATION www .aerocomm.com Figure 3: Network Depth Maximum Nu mber of Chi ldren pe r Parent The Maximum Number of Children specifies the total number of Children that can be conne cted directly to a parent device on the current Networ k.
THEORY OF OPERATION 16 64-bit MAC ad dress The 64-bit MAC address consists of a 40-bit Organizat ionally Uniq ue Identifier (OUI) and a 24-bit address programmed by the ma nufacturer.
17 ZB2430 User’ s Manual - v1.6 THEORY OF OPERATION www .aerocomm.com Figure 4: ZigBee AODV Figure 5: ZigBee Route Reque st.
THEORY OF OPERATION 18 One of two things will happen when Nodes 1 and 2 receive the RREQ from Node 0: • If a route is known or if they are the destinat ion radio, they can send a Route Reply (RREP) back to Node 0. • If they do not know the route and are also not the destination radio, they will rebroadcast the RREQ to their neighbors.

www .aerocomm.com S ERIAL I NTERFACE 6 The ZB2430 transceiver module interfaces to the OEM Ho st vi a an asynchronous 3. 3V serial UART interface; allowing the module to be easily integrated in to any 3.3V system without requiring an y level transla tion.
21 ZB2430 User’ s Manual - v1.6 SERIAL INTERFACE www .aerocomm.com SERIAL INTERFACE BAUD RATE In order for the OEM Host and a transceiver to communicate over the serial interface they need to have the same serial data rate. This value de termines the baud rate used for communicating over the serial interface to a tr ansceiver.
SERIAL INTERFACE 22 INTERFACE TIMEOUT / RF PACKET SIZE Interface Timeout – Interface Time out specifie s a maximum b yte gap between consecutive bytes. Whe n that byte gap is exceeded, the bytes in the transmit buffer are proc essed as a complete packet.

SERIAL INTERFACE 24 NETWORKING PAN ID - PAN ID (EEPROM address 0x79) is a 16-bit field and is similar to a password or network number and helps differentiate collocated networks. A transceive r will not be associated with a networ k unless its PAN ID and Channel Number match that of the Coordina tor.
25 ZB2430 User’ s Manual - v1.6 SERIAL INTERFACE www .aerocomm.com The example shown in Figure 8 below enables all 2.4GHz channels for possible use by selecting 0x07FFF800 as the Channel Mask. The Channel Mask enables you to allow all or to exclude specific channels from selection.
SERIAL INTERFACE 26 POWER DOWN MODES Power down modes allow the ZB2430 to operate at minimum current co nsumption while not in use. The ZB2430 provides two such modes (End Devices only).
27 ZB2430 User’ s Manual - v1.6 SERIAL INTERFACE www .aerocomm.com ENGINEER’S TIP Transmitting and Receiving data with a sleeping End Device. • Data sent to the radio over the U ART while it is sleeping will be lost. If the mo dule wakes while receiving data over the UART, it will only see the data received since waking up.
www .aerocomm.com C ONFIGURING THE ZB2430 7 The ZB2430 can be configured using the CC Configuration Co mmands. These commands can be issued using either Hardware or Software Configuration. To use Hardware Configuration, the Command /Data pin of a transceiver must be asserted Low.
29 ZB2430 User’ s Manual - v1.6 CONFIGURING THE ZB2430 www .aerocomm.com AT COMMANDS The AT Command mode implemented in the ZB2430 creates a virtual version of the Command /Data pin.

www .aerocomm.com API O PERATION 9 API Operation is a powerful alternative to the default Transparent operation of the ZB2430 and provides dynamic packet routing and packet accounting abilities to the OEM Host without requiring extensive prog ramming by the OEM Host.
API OPERATION 42 *Note: Send Data Co mplete may report a fail ure though the packet arrived due to t iming issues. It will never report successful though unless the packet absolutely arrived. Figure 13: Send Data Co mplete packet format API Receive Pa cket By default, the source MAC is not included in the received data string sent to the OEM Host.
www .aerocomm.com ZB2430 A DDRESSING 10 Every ZB2430 transceiver module has a unique static 64- bit MAC address that is p rogrammed at the factory. Upon joining the network, the device is assigned a 16-bit NWK Ad dress. The NWK address onl y changes on initial power-up and when a NV Reset command is issued to the radio.
