Do not Connect Function Has internal connection, for Aerocomm use only. Test Mode – When pulled logic Low and then applying power or resetting, the transceiver’s serial interface is forced to a 9600, 8-N-1 rate. To exit Test mode, the transceiver must be reset or power-cycled with Test Mode pulled logic High or disconnected Note: Because this mode 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. 13 18 I/O GIO_4 / AD_1 Has Internal connection. Reserved for future GPIO. 14 5 I UP_Reset RESET – Controlled by the ZB2430 for power-on reset if left unconnected. After a stable power-on reset, a logic Low pulse will reset the transceiver. 15 11 I CMD/Data When logic Low, the transceiver interprets OEM Host data as command data. When logic High or floating, the transceiver interprets OEM Host data as transmit data. 16 20 O In Range When logic Low, the transceiver is associated with a parent and has been assigned a 16-bit Network Address. The Coordinator will report In Range after selecting a clear channel to operate. 17 16 I RTS Request to Send – When enabled in EEPROM, the OEM Host can take this High when it is not ready to accept data from the transceiver. NOTE: Keeping RTS High for too long can cause data loss due to buffer overflow.2 SPECIFICATIONS ZB2430 User’s Manual - v1.6 Table 2: Pin Definitions for the ZB2430 transceiver SMT Pin Pluggable Pin Type Signal Name 18 12 O CTS 19 14 I/O GIO_8 / AD_5 20 13 O Sleep Ind. 21 17 I/O GIO_6 / AD_3 Has Internal connection.

When logic Low, transceiver is in sleep mode. When logic High, transceiver is awake. 1. May be left disconnected on ZB2430-D devices. 2. Feature not implemented at time of release. ENGINEER’S TIP Design Notes: • All I/O is 3.3V TTL. • All inputs are weakly pulled High (20k) and may be left floating during normal operation. When implemented, RTS will be weakly pulled Low. • Minimum Connections: VCC, VPA, GND, TXD, & RXD. • Signal direction is with respect to the transceiver. • Unused pins should be left disconnected. www.aerocomm.com 5 H ARDWARE I NTERFACE 3 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. www.aerocomm.com 7 T ERMS & D EFINITIONS 4 Ad-Hoc Network: A wireless network composed of communicating devices without preexisting infrastructure. Typically created in a spontaneous manner and is self-organizing and self-maintaining. Association: The process of joining a ZigBee PAN. A device joins the Network by joining a Coordinator or Router which has previously associated with the Network. Upon joining, the Parent device issues a 16-bit Network Address to the device. Broadcast: Broadcast packets are sent to multiple radios. The ZB2430 allows several different broadcast types including broadcast to all devices & broadcast to Coordinator & all Routers. Broadcast jitter: The random delay which is automatically introduced by a device before relaying a broadcast packet to prevent packet collisions. Channel: The frequency selected for data communications within the PAN. The channel is selected by the Network Coordinator on power-up. Channel Mask: The Channel Mask is a 32-bit field which specifies the range of allowable channels that the radio has to select from when choosing an RF channel. Valid only when Channel Select mode is enabled in EEPROM. Clear Channel Assessment: An evaluation of the communication channel prior to a transmission to determine if the channel is currently occupied. Energy Scan: A sweep of the entire frequency band which reports noise readings on every channel & is also capable of detecting Coordinators and reporting their Channel location. FFD: Full Function Device. The Network Coordinator & Routers are examples of FFD’s. IEEE 802.15.4: IEEE standard for Low-Power Wireless Personal Area Networks (WPAN’s). Specifies the physical interface between ZigBee devices. MAC Address: A unique 64-bit address assigned to each radio. This address cannot be modified and never changes. It is used by the network to identify the device when assigning 16-bit Network Addresses. Maximum Network Depth: The maximum number or Routers (hops) that a device can be away from the Coordinator. The current profile limit is 5. Maximum Number of Routers: The total number of children that can serve as Routers for a Network device. The current profile limit is 6. www.aerocomm.com TE R M S & D E F I N I T I O N S ZB2430 User’s Manual - v1.6 Maximum Number of Children: 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 Routers and 14 End Devices. Mesh Network: An interconnection of nodes where nodes are permitted to transmit data directly to any other node. Neighbor Table: A table used by the Coordinator and Router(s) to keep track of other devices operating in the same coverage area. Network Address: The unique 16-bit address assigned to a device upon joining a PAN. This address is used for routing messages between devices and can be different each time a device is powered on. The Network Coordinator will always have a Network Address of 0x0000. Note that addresses are not assigned in numerical order. Operating Channel: The specific frequency selected for data communications. The operating channel is determined by the Coordinator on power-up. Orphan Device: A device which has lost communication contact with or information about its Parent device. PAN: Personal Area Network. Includes a Network Coordinator and one or more Routers/End Devices. The Network formation is determined by the Maximum Network Depth, Maximum Number of Routers, and Maximum Number of Children. PAN ID: Similar to a Network ID. Devices which are operating with different PAN ID’s will not be associated to the same network. Parent/Child: When a device joins the Network, it becomes a child of the device with which it is associated. Similarly, the device with which it associated becomes its parent device. Network devices can have multiple children, but only one parent. End Devices cannot be parents and are always children of the Coordinator or a Router. The Coordinator does not have a parent device. POS: Personal Operating Space. The area within reception range of a specific device. Profile: A collection of device descriptions, which together form a coorperative application. Devices utilizing different profiles will only support very basic inter-communications. The ZB2430 uses a private profile as specified by Aerocomm. RFD: Reduced Function Device. The End Device is an example of an RFD. Route Discovery: An operation using RREQ and RREP’s in which a ZigBee Coordinator or Router discovers a route to a device outside its POS. Route Reply (RREP): A ZigBee command used to reply to a Route Request command. www.aerocomm.com 9 10 TE R M S & D E F I N I T I O N S 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. The entire route is not stored, only the first step in the route. Star Network: A network employing a single, central device through which all communication between devices must pass. TX Cost: A counter of transmission successes/failures. TX Cost starts at 0x00, increments by one every time a packet fails to be delivered, and decrements by one every time a packet is successfully delivered. TX Cost has a range between 0x00 and 0x04. Unicast: Unicast packets contain a destination address and are received by a single radio only. Unicast packets are point-to-point and do not include Broadcast packets. ZigBee Stack: A Network specification based on the IEEE 802.15.4 Standard for Wireless Personal Area Networks (WPANs). The ZB2430 uses the Z-Stack (designed by TI) v.1.4.2 and complies to the ZigBee 2006 specification. 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 5 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.
