HARDWARE INTERFACE

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

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 (Low), the transceiver will send packets to the OEM Host as they are received.

THEORY OF OPERATION

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 are three device types present in a ZigBee network: Coordinator (Full Function Device), Router (Full Function Device), and End Device (Reduced Function Device). Each network consists of a single Coordinator, optional Router(s), and optional Reduced Function End Device(s).

Coordinator

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).

Router

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).

• 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

• Network address of 0x0000

• 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

• Unique netowork address dynamically assigned by parent

www.aerocomm.com

Page 17

THEORY OF OPERATION

End Device

While Coordinators and Routers can communicate with any device type, End Devices can communicate only through 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 sleeping End Device.

• 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

• Unique network address dynamically asssigned by parent

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 directly 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 have their messages routed by 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.

Page 18

ZB2430 User’s Manual - v1.6

Figure 1: ZigBee Network Topologies

THEORY OF OPERATION

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.

www.aerocomm.com

Page 19

THEORY OF OPERATION

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 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 15).

Maximum Network Depth

The Coordinator has a depth of zero and its Children have a depth of 1. Maximum Network Depth specifies the maximum number of hops (Routers) that a node can be away from the Coordinator. The Home Lighting & Controls profile limits the maximum network depth to 5.

Page 20

ZB2430 User’s Manual - v1.6

Figure 3: Network Depth

THEORY OF OPERATION

Maximum Number of Children per Parent

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.

www.aerocomm.com

Page 21

THEORY OF OPERATION

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 only resets when an NV Reset command is issued performed or NV Restore is disabled in EEPROM (EEPROM address 0x45, bit-3).

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.

Table 3: Device Table Example

Index MAC Address (64-bit) NWK Address (16-bit)

0 0x00 0x00 0x00 0x50 0x67 0x12 0x34 0x56 0x0000

1 0x00 0x00 0x00 0x50 0x67 0x16 0x45 0x34 0x0001

2 0x00 0x00 0x00 0x50 0x67 0x34 0x21 0x78 0x143E

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 17).

THEORY OF OPERATION

Figure 5: ZigBee Route Request

www.aerocomm.com

Page 23

THEORY OF OPERATION

One of two things will happen when Nodes 1 and 2 receive the RREQ from Node 0:

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 18). 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.

• 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.

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 19). 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.

SERIAL INTERFACE

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 41.

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.

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.

Stop Bit Delay - For systems using the RS-485 interface, the RS-485 DE pin might be deasserted Low too quickly at the end of a packet (especially at slower interface baud rates). Stop Bit Delay (EEPROM address 0x3F) controls how long RS-485 DE should be left High at the end of a packet before dropping it Low and disabling the RS-485 driver circuitry. Generally, it should be set greater than or equal to two byte times.

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.

Page 28

ZB2430 User’s Manual - v1.6

SERIAL INTERFACE

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 20, 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 0x5B)

• An Interface Timeout occurs (EEPROM address 0x58)

After sending the packet over the RF 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 radio’s CTS 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 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 the data in its buffer. Once RTS beginning with any data stored in its buffer.

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 radio. CTS 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 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 and the size of the packets.

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 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.

RF Channel Number

Range (0x40)

Channel Select - When enabled in EEPROM (EEPROM address 0x56, bit-3) the Coordinator will select a 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 or another network is detected, it will change to the next channel. This continues for all the channels and then the clearest channel is selected.

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 it’s network.

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.

The Channel Mask enables 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 or pin interupt)

• 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.

mode occurs after device has successfully associated with Network.

Automatic transition to Wake mode occurs after an EEPROM selectable period or manual transition when Sleep_Int

is pulled logic Low.

Manual transition to Wake mode occurs after Sleep_Int

is pulled logic Low.

ZB2430: 0.5 uA ZB2430-100: 7.6 uA

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 by the End Device Wake time (EEPROM address 0x3B), 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 RF packets to the module will not keep it awake unless you enable Modify Wake upon RX in EEPROM (EEPROM address 0x45, bit-5).

• When sending data for the module to transmit, it is recommended that the module be forced awake using the Sleep_Int

• While the module is being kept awake using the Sleep_Int its Parent Device based on the Wake Poll rate specified in EEPROM (EEPROM address 0x3C) for as long as it is awake.

CONFIGURING THE ZB2430

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 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 detailed command information, please refer to the command descriptions immediatly following the Quick Reference Table.

API OPERATION

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.

API Receive Packet

By default, the source MAC is not included in the received data string sent to the OEM Host. For applications where multiple radios are sending data, it may be necessary to determine the origin of a specific data packet. When API 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 ADDRESSING

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 and when a NV Reset command is issued to the radio.

In Figure 15 four nodes with the three LSBs of each of their MAC addresses are shown.

Figure 15: ZigBee Addressing by MAC - Node 0 to Node 3

In previous sections (see “Mesh Routing (AODV)” on page 16), 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

ADVANCED NETWORK COMMANDS

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 is stored in NV RAM in stores information about neighboring devices which are operating with teh same Channel Mask, but no necessarily the same channel. The command format is shown in Figure 17.

Command Definitions

• Start Index: Starting index within the Neighbor Table to begin reporting.

• Count: Number of entries to include in Neighbor Table. Maximum number of indexes = 8 (Coordinator and Routers) and 4 (End Devices).

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.
