H ARDWARE I NTERFACE
PIN DEFINITIONS
Generic I/O
Both GIn and GOn pins serve as generic input/output pins. Reading and writing of these pins can be performed onthe-fly using CC Commands.
RXD and TXD
The ZB2430 accepts 3.3 VDC TTL level asynchronous serial data from the OEM Host via the RXD pin. Data is sent
from the transceiver, at 3.3V levels, to the OEM Host via the TXD pin.
Test/Sleep Int.
Test Mode - When pulled logic Low before applying power or resetting, the transceiver's serial interface is forced to
9600, 8-N-1 (8 data bits, No parity, 1 stop bit): regardless of actual EEPROM setting. The interface timeout is also set
to 3 ms and the RF packet size is set to the default size of 0x54 (84 bytes). To exit, the transceiver must be reset or
power-cycled with Test pin logic High or disconnected.
Note: Because this pin disables some modes of operation, it should not be permanently pulled Low during normal
operation.
Sleep Mode Interrupt - When logic Low, forces End Device to wake up from sleep mode. When logic High, allows End
Device to sleep and wake-up according to specified poll rate. Sleep Mode interrupt function available on End
Devices only.
UP_Reset
UP_Reset provides a direct connection to the reset pin on the ZB2430 microprocessor and is used to force a soft
reset. For a valid reset, reset must be asserted Low for an absolute minimum of 250 ns.
Command/Data
When logic High, the transceiver interprets incoming serial data as transmit data to be sent to other transceivers.
When logic Low, the transceiver interprets incoming serial data as command data. When logic Low, data packets
from the radio will not be transmitted over the RF interface however incoming packets from other radios will still be
received.
In Range
The In Range pin will be driven low when the radio is associated with a network. In Range will always be driven low on
a Coordinator.
RTS Handshaking*
With RTS mode disabled, the transceiver will send any received data to the OEM Host as soon as it is received.
However, some OEM Hosts are not able to accept data from the transceiver all of the time. With RTS enabled, the
OEM Host can prevent the transceiver from sending it data by de-asserting RTS (High). Once RTS is re-asserted
(Low), the transceiver will send packets to the OEM Host as they are received.
www.aerocomm.com
HARDWARE INTERFACE
ZB2430 User’s Manual - v1.6
Note: Leaving RTS de-asserted for too long can cause data loss once the transceiver's receive buffer reaches
capacity.
*Feature not implemented at time of release.
CTS Handshaking
If the transceiver buffer fills up and more bytes are sent to it before the buffer can be emptied, data loss will occur. The
transceiver prevents this loss by deasserting CTS High as the buffer fills up and asserting CTS Low as the buffer is
emptied. CTS should be monitored by the Host device and data flow to the radio should be stopped when CTS is
High.
Sleep Ind.
Sleep Indicator output. Sleep Ind. can be used to determine whether or not the transceiver is sleeping. When logic
Low, the transceiver is in sleep mode. When logic High, the transceiver is awake.
AD In
AD In can be used as a cost savings to replace Analog-to-Digital converter hardware with the onboard 12-bit ADC.
Reading of this pin can be performed locally using the Read ADC command found in the On-the-Fly Control
Command Reference.

ZigBee Alliance: An association of companies working together to create a low-cost, low power consumption, twoway wireless communications standard (http://www.zigbee.org).
T HEORY OF O PERATION
IEEE 802.15.4 & ZIGBEE OVERVIEW
The ZB2430 uses the ZigBee protocol stack, a network layer protocol which uses small, low power digital transceivers
based on the IEEE 802.15.4 hardware standard. The 802.15.4 standard is a specification for a cost-effective, low data
rate (<250 kbps), 2.4 GHz or 868/928 MHz wireless technology designed for personal-area and device-to-device
wireless networking.
The IEEE 802.15.4 standard specifies the hardware requirements, including frequency bands, receiver sensitivity,
modulation and spreading requirements. The ZigBee layer is the software layer that sits atop the 802.15.4 PHY/MAC
layer and performs all packet routing and mesh networking.
There a three device types allowed in a ZigBee network: Coordinator, Router, and End Device. Each network consists
of a single Coordinator, optional Router(s), and optional Reduced Function End Device(s).
C o o r d i na t o r
The Coordinator is responsible for establishing the
operating channel and PAN ID for the entire Network.
Once the Coordinator has established a Network, it allows
Routers and End Devices to join the Network; assigning
each device a unique 16-bit Network Address.
The Coordinator is intended to be mains powered (always
on).
• One Coordinator per Network
• Establishes Channel and PAN ID
• Responsible for Network formation and
maintenance
• Full Function Device
• Packet routing capabilities
• Mains powered (always on)
• Power down modes are not supported
R o u t er
Routers are responsible for creating and maintaining
Network information and determining the optimal route for
a data packet. Routers must first associate with the
Network before other devices can join through them.
Routers are intended to be mains powered (always on).
• Multiple Routers can be used
• Allows other Routers/End Devices to join
the Network
• Full Function Device
• Packet routing capabilities
• Mains powered (always on)
• Power down modes are not supported
En d D ev ic e
While Coordinators and Routers can communicate with
any device type, End Devices can communicate only with
their parent device. Ideally the End Devices will be in
sleep mode all the time. When they have data to send,
they wake up, send the data and then go back to sleep.
The Parent (Coordinator/Router) of an End Device should
be mains powered to allow it to store data to be sent to
the End Device while it sleeps.
www.aerocomm.com
• Multiple End Devices can be used
• No packet routing capabilities
• Can communicate with other devices in
the Network through its Parent Device
• Reduced Function Device
• Mains or battery powered
• Power down modes are supported
12
THEORY OF OPERATION
CREATING A NETWORK
The IEEE 802.15.4 MAC provides support for two wireless network topologies: star and mesh. The management of
these networks is performed by the ZigBee layer. All devices, regardless of topology, participate in the network using
their unique 16-bit address assigned by the Coordinator.
Mesh
The mesh topology allows any Full Function Device (Coordinator or Router) to communicate with any other device
within its range and to have messages relayed to devices which are out of range via multi-hop routing of messages.
While a FFD device can communicate with a Reduced Function Device (RFD), RFD’s cannot directly route messages
and must communicate through their parent device (Coordinator or Router). ZigBee mesh enables the formation of
more complex networks, including ad-hoc, self-organizing, and self-healing structures.
Figure 1 shows a typical ZigBee network architecture.
Figure 1: ZigBee Network Topologies
PARENT/CHILD RELATIONSHIP
ZigBee uses a parent/child relationship between network devices. The network begins with the Coordinator as the
first device on the network. When a new device (Router or End Device) associates with the Coordinator, it becomes a
child of the Coordinator and similarly, the Coordinator becomes a parent of that device. If a second device joins the
network, the Coordinator will once again become the parent and the device will become a child of the Coordinator. If
a device is not in range of the Coordinator, it subsequently joins the network through a Router, and becomes a child of
that Router. Network devices can have multiple children, but only one parent. By design, End Devices cannot be
parents and are always children of the Coordinator or a Router.
THEORY OF OPERATION
ZB2430 User’s Manual - v1.6
Figure 2: Parent/Child Relationship
NETWORK LIMITATIONS
The ZigBee network structure and ultimate size are specified by Stack profiles. The Stack profiles define the
maximum number of Layers, maximum number of Children per Parent, & maximum number of Routers that can be
Children. These parameters are set during code compilation and cannot be altered after compilation. The ZB2430
uses the restricitions specified by the Home Lighting & Controls profile.
The ZigBee Coordinator determines the maximum number of children any device within its network is allowed. Of
these children, a maximum number or routers can be router-capable devices; while the remainder shall be reserved
for end devices. Each device has an associated depth which indicates the minimum number of hops a transmitted
packet must travel to reach the ZigBee Coordinator (see Figure 3: "Network Depth" on page 14).
Maximum Network Depth
The Coordinator has a depth of zero and its Children have a depth of 1. Maximum Network Depth specifies the

The Maximum Number of Children specifies the total number of Children that can be connected directly to a parent
device on the current Network. The Home Lighting and Control profile specifies the maximum number of children the
Coordinator and Routers can have associated with them to be 20. Of those 20 Children, a maximum of 6 Routers can
be router-capable devices while the remainder shall be End Devices.
ZIGBEE ADDRESSING
The IEEE 802.15.4 standard from which the ZigBee protocol was derived specifies two types of addressing modes:
• 16-bit Network Address
• 64-bit MAC Address
16-bit Network Address
The Network Address is a unique address on the network. The Coordinator always has a Network Address of 0x0000
and it will assign a Network Address to each radio within its range. Routers will then assign Network Addresses to
radios within their range which have not previously been assigned an address. Because the 16-bit address is unique
to each radio on the network, an addressed packet can be sent from any radio on the network to any other radio
located anywhere on the network.
THEORY OF OPERATION
ZB2430 User’s Manual - v1.6
ENGINEER’S TIP
16-bit Network Addresses.
In a ZigBee network, nodes are assigned a 16-bit NWK address according to how the network
formed. By design, the Coordinator will always have a NWK address of 0x0000. The first
Router to that associates with the Coordinator is assigned a NWK address of 0x0001. The
second Router that associates with the Coordinator is assigned an address of 0x143E.
The 16-bit address is persistent through power loss and resets unless an NV Reset is
performed.
64-bit MAC address
The 64-bit MAC address consists of a 40-bit Organizationally Unique Identifier (OUI) and a 24-bit address
programmed by the manufacturer. All ZB2430 transceivers have the same OUI of 0x00 0x00 0x00 0x50 0x67 which
can be used to distinguish Aerocomm devices on a network but cannot be used to route packets throughout the
network.
When a packet needs to be sent to a specific device through the network, the 16-bit network address must be used.
In order to send data to a specific device in the network, the OEM can compile a table which lists the 64-bit MAC and
the corresponding 16-bit Network address (see Table 3 below). The ZB2430’s built-in Discover IEEE Address and
Discover Network Address commands allow the OEM to query the network and discover all available devices that
respond within a fixed period.

Mesh Routing (AODV)
The ZigBee protocol uses the Ad-Hoc On-Demand Distance Vector (AODV) routing algorithm. AODV allows nodes to
pass messages through their neighbors to devices which they cannot communicate directly. This is done by
discovering the routes along which messages can be passed using the shortest route possible.
Figure 4 below shows a typical ZigBee network. The circles surrounding the 4 nodes represent the Personal
Operating Space (POS) of each node. Because of the limited range, each node can only communicate with the
neighboring node(s) next to it. When a node needs to send a message to a node which is not a neighbor, it
broadcasts a Route Request (RREQ) message containing the Source Destination Address, the Network Address of
the Destination radio and a path cost metric.
In the example below, Node 0 needs to send a message to Node 3; however the two are not within communication
range of each other. Node 0’s neighbors are Node 1 and Node 2. Since Node 0 cannot directly communicate with
Node 3, it sends out a RREQ which is heard by Nodes 1 and 2 (see Figure 5: "ZigBee Route Request" on page 16).

15
16
THEORY OF OPERATION
Figure 4: ZigBee AODV
Figure 5: ZigBee Route Request
THEORY OF OPERATION
ZB2430 User’s Manual - v1.6
One of two things happen when Nodes 1 and 2 receive the RREQ from Node 0:
• If a route is known or if they are the destination 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. The message keeps re-broadcasting until the lifespan (specified by
the source radio) expires.
If Node 0 does not receive a reply within a set amount of time, it will rebroadcast the message, this time with a longer
lifespan and a new ID number.
In the example, Node 1 does not have a route to Node 3 and therefore rebroadcasts the RREQ (see Figure 6: "ZigBee
Route Reply" on page 17). Node 2 however, does have a route to Node 3 and therefore replies to the RREQ by
sending out a RREP. Node 2 also sends a RREP to Node 3 so that it knows the route to Node 0.
Figure 6: ZigBee Route Reply
Coordinator Addressing
Since the Coordinator’s NWK address is always 0x0000, it can be addressed using its 16-bit NWK address.
Broadcast Transmissions
Since ZigBee is targeted for large-scale applications in which all radios may not be in range of a single radio,
broadcast packets are retransmitted throughout the network. Broadcast transmissions in ZigBee utilize a passive
acknowledgement mechanism; meaning that the Coordinator and all Routers keep track of whether or not their
neighbor(s) have relayed the broadcast packet and will re-broadcast the packet until all of their neighboring devices
have received the packet. Any device can initiate a Broadcast transmission by programming its Destination Address
with a Broadcast Address (see Table 4 on page 18). Subsequent broadcast transmissions occur every 500ms.

ENGINEER’S TIP
Sending a Broadcast packet.
While ZigBee does provide the means for broadcasting data packets throughout the network,
because of the inherent delays associated with broadcast transmissions overall latency may
increase; especially with larger networks. Because of the added latency and overall effect on
the network, broadcast transmissions within a ZigBee network should be limited.
S ERIAL I NTERFACE
The ZB2430 transceiver module interfaces to the OEM Host via an asynchronous 3.3V serial UART interface; allowing
the module to be easily integrated into any 3.3V system without requiring any level translation. The module can
communicate with any logic and voltage compatible UART; or to any serial device with an additional level translator.
INTERFACE MODES
The ZB2430 has two different types of interface modes:
• Transparent Mode
• API Mode
Transparent Mode
When operating in Transparent Mode, the ZB2430 can act as a direct serial cable replacement in which received RF
data is forwarded over the serial interface and vice versa. Additionally, many parameters can be configured using
either AT commands or by toggling the Command/Data pin on the transceiver. In transparent mode, the radio needs
to be programmed with the Network Address of the desired recipient. The destination address can be programmed
permanently or on-the-fly.
When Transparent Mode is used, data is stored in the TX buffer until one of the following occurs:
• The RF packet size is reached (EEPROM address 0x5A)
• An Interface Timeout occurs (EEPROM address 0x58)
API Mode
API Mode is an 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 programming by the OEM Host. API
Mode utilizes specific frame-based packet formats; specifying various vital parameters used to control radio settings
and packet routing on a packet-by-packet basis. The API features can be used in any combination that suits the
OEM’s application specific needs.
API Mode provides an alternative method of configuring modules and message routing at the OEM Host level; without
requiring the use of Command Mode. The ZB2430 has three API functions:
• Transmit API
• Receive API
• API Send Data Complete
For additional details and examples, please refer to the API section on page 38.

SERIAL INTERFACE
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 determines the baud rate used for communicating over the serial interface to a transceiver.
For a baud rate to be valid, the calculated baud rate must be within ±3% of the OEM Host baud rate.

ENGINEER’S TIP
Using a non-standard baud rate.
The ZB2430 supports a majority of standard as well as non-standard baud rates. To select a
standard baud rate, use the value shown for EEPROM address 0x42 in Table 5 above. To
enable a non-standard baud rate, program EEPROM address 0x42 (Custom Baud Enable) to
0xE3 and then use the equation above to solve for BAUD_M and BAUD_E.
SERIAL INTERFACE
ZB2430 User’s Manual - v1.6
INTERFACE TIMEOUT / RF PACKET SIZE
Interface Timeout – Interface Timeout specifies a maximum byte gap between consecutive bytes. When that byte gap
is exceeded, the bytes in the transmit buffer are processed as a complete packet. Interface Timeout (EEPROM
address 0x58), in conjunction with the RF Packet Size, determines when a buffer of data will be sent out over the RF
as a complete RF packet, based on whichever condition occurs first.
RF Packet Size - RF Packet Size is used in conjunction with Interface Timeout to determine when to delineate
incoming data as an entire packet based on whichever condition is met first. When the transceiver receives the
number of bytes specified by RF Packet Size (EEPROM address 0x5A) without experiencing a byte gap equal to
Interface Timeout, that block of data is processed as a complete packet. Every packet the transceiver sends over the
RF contains extra header bytes not counted in the RF Packet Size. Therefore, it is much more efficient to send a few
large packets than to send many short packets.
FLOW CONTROL
Although flow control is not required for transceiver operation, it is recommended to achieve optimum system
performance and to avoid overrunning the ZB2430’s serial buffers. The ZB2430 uses seperate buffers for incoming
and outgoing data.
RXD Data Buffer and CTS
As data is sent from the OEM Host to the radio over the serial interface, it is stored in the ZB2430’s buffer until the
radio is ready to transmit the data packet. As discussed in “Interface Modes” on page 19, the radio waits to transmit
the data until one of the following conditions occur (whichever occurs first):
• The RF packet size is reached (EEPROM address 0x5A)
• An Interface Timeout occurs (EEPROM address 0x58)
The data continues to be stored in the buffer until the radio receives an RF Acknowledgement (ACK) from the
receiving radio (addressed mode), or all transmit retries/broadcast attempts have been utilized. Once an ACK has
been received or all retries/attempts have been exhausted, the current data packet is removed from the buffer and the
radio will begin processing the next data packet in the buffer.
To prevent the radio’s RXD buffer from being overrun, it is strongly recommended that the OEM Host monitor the
radio’s CTS output. When the number of bytes in the RXD buffer reaches the value specified by CTS_ON (EEPROM
address 0x5C), the radio de-asserts (High) CTS to signal to the OEM Host to stop sending data over the serial
interface. CTS is re-asserted after the number of bytes in the RXD buffer is reduced to the value specified by
CTS_OFF (EEPROM address 0x5D); signalling to the OEM Host that it may resume sending data to the transceiver.
Note: It is recommended that the OEM Host cease all data transmission to the radio while CTS is de-asserted (High);
otherwise potential data loss may occur.
TXD Data Buffer and RTS
As data to be forwarded to the OEM Host accumulates, it is stored in the ZB2430’s outgoing buffer until the radio is
ready to begin sending the data to the OEM Host. Once the data packet has been sent to the Host over the serial
interface, it will be removed from the buffer and the radio will begin processing the next data packet in the buffer.
With RTS Mode disabled, the transceiver will send any data to the OEM Host as soon as it has data to send. However,
some OEM Hosts are not able to accept data from the transceiver all of the time. With RTS Mode Enabled, the OEM
Host can prevent the transceiver from sending it a data by de-asserting RTS (High), causing the transceiver to store
www.aerocomm.com
21
22
SERIAL INTERFACE
the data in its buffer. Once RTS is re-asserted (Low), the transceiver will continue sending data to the OEM Host,
beginning with any data stored in its buffer.
Note: Leaving RTS de-asserted for too long can cause data loss once the radio’s TXD buffer reaches capacity.
ENGINEER’S TIP
Can I implement a design using just TXD, RXD and Gnd (Three-wire Interface)?
Yes. However, it is strongly recommended that your hardware monitor the CTS pin of the
radio. CTS is taken High by the radio when its interface buffer is getting full. Your hardware
should stop sending at this point to avoid a buffer overrun (and subsequent loss of data).
You can perform a successful design without monitoring CTS. However, you need to take into
account the amount of latency the radio adds to the system, any additional latency caused by
Transmit Retries, how often you send data, non-delivery network timeouts and interface data
rate.
Aerocomm can assist in determining whether CTS is required for your application.
NETWORKING
PAN ID - PAN ID (EEPROM address 0x78) is a 16-bit field and is similar to a password character or network number
and helps differentiate collocated networks.. A transceiver will not be associated with a network unless its PAN ID and
Channel Number match that of the Coordinator. Range is 0x0000 to 0x3FFF.
RF Channel Number - (EEPROM Address 0x40) Channels 0x0B - 0x1A; 5 MHz spacing. The transceiver will operate
only on the RF Channel Number specified in the EEPROM.
Note: The ZB2430-Q is not approved for use on channel 0x1A and the channel number should therefore be selected
accordingly.

Channel Select - When enabled in EEPROM (EEPROM address 0x56, bit-3) the Coordinator will select the channel
permitted by the channel mask with the least amount of energy present. The Coordinator will start on the first channel
and if RF energy is detected, it will change to the next channel until a clear channel is found.
When a Router is powered on, it will scan each channel; periodically sending beacons and searching for a parent.
When the parent receives a beacon from the Router, it sends an acknowledgement to the Router, and the Router is
associated with that parent.
When disabled in EEPROM, the Coordinator will use the RF Channel programmed at EEPROM address 0x40 to
establish itself on.
Channel Mask - The Channel Mask (EEPROM Address 0x30) is a 32-bit field which specifies the range of allowable
channels that the radio can select from when choosing an RF channel. In order for two devices to communicate, a
common channel must be selected. At least one channel must be selected (set to 1).
To use the Channel Mask, enable Channel Select (EEPROM Address 0x56, bit 3). When Channel Select is enabled,
the radio disregards the Channel specified at EEPROM address 0x40. When Channel Select is disabled, only the
Channel specified at EEPROM Address 0x40 will be used.
Examples:
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 allows you to allow all or to exclude specific channels from selection. The
example in Figure 9 shows channels 0x14-0x1A as the only available channels to select from. Finally Figure 10 below
shows channels 0x0B-0x10 as the only available channels to select from.

POWER DOWN MODES
Power down modes allow the ZB2430 to operate at minimum current consumption while not in use. The ZB2430
provides two such modes (End Devices only).
• Cyclic Sleep (Wake periodically based on software-controlled timer)
• Deep Sleep (Wake on pin interrupt)
In order for a module to transition into Sleep mode, the Sleep_Int pin (pin 12) must be logic High or floating. If this pin
is pulled Low, the device will be forced out of Sleep mode and will not be allowed to Sleep until the pin returns to the
High state. While in Sleep mode, the module will not transmit/receive data until after waking up.

Cyclic Sleep
In Cyclic Sleep mode the End Device will wake periodically to request data from its Parent device. The rate at which
the module wakes up to check for data is adjustable in EEPROM (EEPROM address 0x34, 16-bits) in 1 ms increments
with a default setting of 1000ms. The device will wakeup for the period specified, send a data request to its Parent,
and then return to sleep until the next cycle.
Note: Setting the sleep rate to 0x0000 forces the module into Deep Sleep mode (see below).
Deep Sleep
Deep sleep mode is a power-down mode in which the ZB2430 automatically transitions to Sleep mode after having
associated with the Network. While in Deep Sleep mode, the device will not wake up until interrupted by the Sleep_Int
pin. To wake the device out of Deep Sleep mode, Sleep_Int must be pulled logic Low. The device will return to Deep
Sleep mode after Sleep_Int is returned to the High state.
ENGINEER’S TIP
Transmitting and Receiving data with a sleeping End Device.
• Data sent to the radio over the UART while it is sleeping will be lost. If the module wakes
while receiving data over the UART, it will only see the data received since waking up.
• Incoming data to the module will not keep it awake.
• When sending data for the module to transmit, it is recommended that the module be forced
awake using the Sleep_Int pin until the module is finished transmitting the data.
• While the module is being kept awake using the Sleep_Int pin, it will still send data requests
to its Parent Device based on the Poll rate specified in EEPROM for as long as it is awake.
• A Parent will only store data for an End Device for a max. of 2000ms before discarding it.

ZB2430 User’s Manual - v1.6
AT COMMANDS
The AT Command mode implemented in the ZB2430 creates a virtual version of the Command/Data pin. The “Enter
AT Command Mode” Command asserts this virtual pin Low (to signify Command Mode) and the “Exit AT Command
Mode” Command asserts this virtual pin High (to signify Data). Once this pin has been asserted Low, all On-the-Fly
CC Commands documented in the manual are supported.
On-the-Fly Control Commands
The ZB2430 transceiver contains static memory that holds many of the parameters that control the transceiver
operation. Using the “CC” command set allows many of these parameters to be changed during system operation.
Because the memory these commands affect is static, when the transceiver is reset, these parameters will revert back
to the settings stored in the EEPROM. While in CC Command mode using pin 15 (Command/Data), the RF interface
of the transceiver is still active. Therefore, it can receive packets from remote transceivers while in CC Command
mode and forward these to the OEM Host.
While in Command mode, the incoming RF interface of the transceiver is active and packets sent from other
transceivers will still be received; however no outgoing RF packets will be sent. The transceiver uses Interface
Timeout/RF Packet Size to determine when a CC Command is complete. Therefore, there should be no delay
between each character as it is sent from the OEM Host to the transceiver or the transceiver will not recognize the
command.
When an invalid command is sent, the radio discards the data and no response is sent to the OEM Host. Table 8
below shows a quick summary of the basic configuration & diagnostic commands available on the ZB2430. For

API O PERATION
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 programming by the OEM
Host.. API operation utilizes specific packet formats; specifying various vital parameters used to control radio settings
and packet routing on a packet-by-packet basis. The API features can be used in any combination that suits the
OEM’s specific needs and can be different between radios operating on the same network.
API Transmit Packet
API Transmit Packet is a powerful command that allows the OEM Host to send data to a single or multiple (broadcast)
transceivers on a packet-by-packet basis. This can be useful for many applications; including polling and/or mesh
networks.
API Transmit Packet is enabled when bit-1 of the API Control byte is enabled. The OEM Host should use the format
shown in Figure 12 below to transmit a packet over the RF.

API Send Data Complete
API Send Data complete can be used as a software acknowledgement indicator. When a radio sends an addressed
packet, it will look for a received acknowledgement (transparent to the OEM Host). If an acknowledgement is not
received, the packet will be retransmitted until one is received or all retries have been exhausted.
For applications where data loss is not an option, the OEM Host may wish to monitor the acknowledgement process
using the API Send Data Complete. If an acknowledgement is not received (Failure), the OEM Host can send the
packet to the transceiver once again.
API Send Data Complete is enabled when bit-2 of the API Control byte is enabled. The transceiver sends the OEM
Host the data shown in Figure 13 upon receiving an RF acknowledge or exhausting all attempts.

By default, the source MAC is not included in the received data string sent to the OEM Host. For applications where

Receive Packet is enabled, all packets received by the transceiver will include the MAC address of the source radio as
well as an RSSI indicator which can be used to determine the link quality between the two.
API Receive Packet is enabled when bit-0 of the API Control byte is enabled. Upon receiving a RF packet, the radio
sends its OEM Host the data as shown in Figure 14 below.

ZB2430 A DDRESSING

Every ZB2430 transceiver module has a unique static 64-bit MAC address that is programmed at the factory. Upon
joining the network, the device is assigned a 16-bit NWK Address. The NWK address only changes on initial power-up
adn when an NV Reset command is issued to the radio.
In Figure 15 below, 4 nodes with each of their associated MAC addresses are shown.
Figure 15: ZigBee Addressing by MAC - Node 0 to Node 3
In previous sections (see “Mesh Routing (AODV)” on page 15), the Ad-Hoc On-Demand Vector routing protocol,
Route Requests and Replies were discussed. Fortunately, the routing, RREQ’s and RREP’s are not left up to the OEM
Host and are all taken care of by the ZigBee protocol embedded in the ZB2430. A message can therefore be sent to
a device anywhere on the network once its 16-bit NWK address is known.
Using the same example as before, assume that Node 0 needs to send a message to Node 3 which is out of Node 0’s
range. This can be done using the procedure below (note that the underlined values will vary from radio to radio):
1. Enter AT Command Mode: ..................................................... 0x41 0x54 0x2B 0x2B 0x2B 0x0D
2. Wait for command response:.................................................. 0xCC 0x43 0x4F 0x0D

Some applications may require a more extensive knowledge of the Network and its current configuration. For this
reason, the ZB2430 includes several advanced commands which can be issued anytime the radio is in Command
mode. Each of these commands include a 16-bit Return Mask which allows the OEM Host to select the information
returned in the command response.
Note: All unused bits in the Return Mask should be set to “0”.
Read Neighbor Table
The Neighbor Table stores information about neighboring devices which are operating on the same RF Channel but
different PAN ID. To read a device’s Neighbor Table, use the command format shown in Figure 17 below.

FCC / IC REQUIREMENTS FOR MODULAR APPROVAL
In general, there are two agency classifications of wireless applications; portable and mobile.
Portable - Portable is a classification of equipment where the user, in general, will be within 20 cm of the transmitting
antenna. Portable equipment is further broken down into two classes; within 2.5 cm of human contact and beyond
2.5 cm (Note: Ankles, feet, wrists, and hands are permitted to be within 2.5 cm of the antenna even if the equipment is
designated as being greater than 2.5 cm). The ZB2430 is not agency approved for portable applications. The OEM is
required to have additional testing performed to receive this classification. Contact AeroComm for more details.
www.aerocomm.com
52
COMPLIANCY INFORMATION
Mobile - Mobile defines equipment where the user will be 20 cm or greater from the transmitting equipment. The
antenna must be mounted in such a way that it cannot be moved closer to the user with respect to the equipment,
although the equipment may be moved. (Note: Ankles, feet, wrists, and hands are permitted to be within 20 cm of
mobile equipment).
OEM EQUIPMENT LABELING REQUIREMENTS
WARNING: The OEM must ensure that FCC labeling requirements are met. This includes a clearly visible label on the
outside of the OEM enclosure specifying the appropriate AeroComm FCC identifier for this product as well as the FCC
notice below. The FCC identifiers are listed above.

device must accept any interference received, including interference that may cause undesired operation.
Label and text information should be in a size of type large enough to be readiily legible, consistent with the
dimensions of the equipment and the label. However, the type size for the text is not required to be larger than eight
point.
ANTENNA REQUIREMENTS
WARNING: This device has been tested with a U.FL connector with the above listed antennas. When integrated into
the OEM’s product, these fixed antennas require professional installation preventing end-users from replacing them
with non-approved antennas. Any antenna not listed in the above table must be tested to comply with FCC Section
15.203 for unique antenna connectors and Section 15.247 for emissions. Contact AeroComm for assistance.
Caution: Any changes or modifications not expressly approved by AeroComm could void the user’s authority to
operate the equipment.
WARNINGS REQUIRED IN OEM MANUALS
WARNING: This equipment has been approved for mobile applications where the equipment should be used at
distances greater than 20 cm from the human body (with the exception of hands, feet, wrists, and ankles). Operation
