Page 25: Design Notes
Hardware Design notes Design notes The XBee modules do not require any external circuitry or specific connections for proper operation. However, there are some general design guidelines that we recommend to build and troubleshoot a robust design. Power supply design A poor power supply can lead to poor radio performance, especially if you do not keep the supply voltage within tolerance or if the noise is excessive.
Page 26: Recommended Pin Connections
Hardware Design notes Microwave ovens Batteries Tall electrolytic capacitors Use the following additional guidelines for optimal antenna performance: Do not place XBee modules with the chip antenna inside a metal enclosure. Do not place any ground planes or metal objects above or below the antenna. For the best results, mount the device at the edge of the host PCB.

Page 35: Operation
Operation Basic operational design Basic operational design The XBee-PRO 900HP RF ModuleRF Module uses a multi-layered firmware base to order the flow of data, dependent on the hardware and software configuration that you choose. The following graphic shows a configuration block diagram, with the host serial interface as the physical starting point and the antenna as the physical endpoint for the transferred data.
Page 36: Serial Data
Operation Configuration considerations Serial data A device sends data to the XBee-PRO 900HP RF Module's UART through pin 3 DIN as an asynchronous serial signal. When the device is not transmitting data, the signals should idle high. For serial communication to occur, you must configure the UART of both devices (the microcontroller and the XBee-PRO 900HP RF Module) with compatible settings for the baud rate, parity, start bits, stop bits, and data bits.
Page 37: Force Uart Operation
Operation Configuration considerations If both interfaces are configured, serial data goes out the UART until the SPI_SSEL signal is asserted. After that, all serial communications operate on the SPI interface. If you enable only the UART, then the device only uses the UART and ignores SPI_SSEL. If you only enable the SPI, then the device uses only the SPI.
Page 38: Serial Port Selection
Operation Serial port selection Serial port selection To enable the UART port, configure DIN and DOUT (P3 and P4 parameters) as peripherals. To enable the SPI port, enable SPI_MISO, SPI_MOSI, SPI_SSEL , and SPI_CLK (P5 through P9) as peripherals. If you enable both ports then output goes to the UART until the first input on SPI.
Page 39 Operation UART flow control the serial transmit buffer does not have enough space for all of the data bytes, it discards the entire RF data packet. The UART Data Present Indicator is a useful feature when using RTS flow control. When enabled, the DIO1 line asserts (low asserted) when UART data is queued to be transmitted from the module.

Slave mode receives the clock signal and data from the master and returns data to the master. The following table shows the signals that the SPI port uses on the device. Signal Function SPI_MOSI...
Page 42: Spi Signals
SPI operation SPI signals The device transmits and receives data with the most significant bit first using SPI mode 0. This means the CPOL and CPHA are both 0. We chose Mode 0 because it is the typical default for most microcontrollers and simplifies configuring the master.
Page 43: Low Power Operation
By default, Digi configures DIO8 (SLEEP_REQUEST) as a peripheral and during pin sleep it wakes the device and puts it to sleep. This applies to both the UART and SPI serial interfaces.
Page 44: Spi Parameters
SPI operation SPI parameters SPI parameters Most host processors with SPI hardware allow you to set the bit order, clock phase and polarity. For communication with all XBee-PRO 900HP RF Modules, the host processor must set these options as follows: Bit order: send MSB first Clock phase (CPHA): sample data on first (leading) edge Clock polarity (CPOL): first (leading) edge rises...

Page 46: Serial Modes
Modes Serial modes Serial modes The firmware operates in several different modes. Two top-level modes establish how the device communicates with other devices through its serial interface: Transparent operating mode and API operating mode. Use the AP command to choose Serial mode. XBee-PRO 900HP RF Modules use Transparent operation as the default serial mode.
Page 47 Modes Serial modes Feature Description Transparent mode features Simple interface All received serial data is transmitted unless the device is in Command mode Easy to support It is easier for an application to support Transparent operation and Command mode API mode features Transmitting RF data to multiple remote devices only requires the Easy to manage data application to change the address in the API frame.
Page 48: Modes Of Operation
Modes Modes of operation Modes of operation Idle mode When not receiving or transmitting data, the device is in Idle mode. During Idle mode, the device listens for valid data on both the RF and serial ports. The device shifts into the other modes of operation under the following conditions: Transmit mode (serial data in the serial receive buffer is ready to be packetized).
Page 49 Modes Modes of operation commands. When you want to read or set any parameter of the XBee-PRO 900HP RF Module using this mode, you have to send an AT command. Every AT command starts with the letters AT followed by the two characters that identify the command and then by some optional configuration values. The operating modes of the XBee-PRO 900HP RF Module are controlled by the AP (API Mode) setting,...
Page 50 Modes Modes of operation The preceding example changes NI (Node Identifier) to My XBee. Multiple AT commands You can send multiple AT commands at a time when they are separated by a comma in Command mode; for example, ATNIMy XBee,AC<cr>. The preceding example changes the NI (Node Identifier) to My XBee and makes the setting active through AC (Apply Changes).
Page 51: Sleep Mode
Modes Modes of operation Exit Command mode 1. Send CN (Exit Command Mode) followed by a carriage return. 2. If the device does not receive any valid AT commands within the time specified by CT (Command Mode Timeout), it returns to Transparent or API mode. The default Command mode timeout is 10 seconds.

Page 53: Sleep Modes
Sleep modes About sleep modes About sleep modes A number of low-power modes exist to enable devices to operate for extended periods of time on battery power. Use the SM command to enable these sleep modes. The sleep modes are characterized as either: Asynchronous (SM = 1, 4, 5).
Page 54: Asynchronous Pin Sleep Mode
Sleep modes Asynchronous pin sleep mode When synchronized, a device in Normal mode relays sync messages that sleep-compatible nodes generate, but does not generate sync messages itself. Once a device in Normal mode synchronizes with a sleeping network, you can put it into a sleep- compatible sleep mode at any time.
Page 55: Synchronous Cyclic Sleep Mode
Sleep modes Synchronous cyclic sleep mode When you use them as preferred sleep coordinator nodes. As aids in adding new nodes to a sleeping network. Note Because sleep support nodes do not sleep, they should be mains powered. Synchronous cyclic sleep mode Set SM to 8 to enter synchronous cyclic sleep mode.
Page 56: Polling
Sleep modes Sleeping routers poller for more than 2.5 times its SP value, then the packet is purged. We suggest setting the SP of the coordinator to the same value as the highest SP time that exists among the pollers in the network.
Page 57: Synchronization Messages
Sleep modes Sleeping routers Synchronization messages A sleep coordinator regularly sends sync messages to keep the network in sync. Unsynchronized nodes also send messages requesting sync information. Sleep compatible nodes use Deployment mode when they first power up and the sync message has not been relayed.
Page 58 Sleep modes Sleeping routers XBee®-PRO 900HP/XSC RF Modules...
Page 59: Become A Sleep Coordinator
Sleep modes Sleeping routers Become a sleep coordinator In DigiMesh networks, a device can become a sleep coordinator in one of four ways: Define a preferred sleep coordinator A potential sleep coordinator misses three or more sync messages Press the Commissioning Pushbutton twice on a potential sleep coordinator Change the sleep timing values on a potential sleep coordinator Preferred sleep coordinator option You can specify that a node always act as a sleep coordinator.
Page 60 Sleep modes Sleeping routers 1. Newer sleep parameters: the network considers a node using newer sleep parameters (SP and ST) as higher priority to a node using older sleep parameters. See Change sleep parameters. 2. Preferred sleep coordinator: a node acting as a preferred sleep coordinator is higher priority to other nodes.
Page 61: Select Sleep Parameters
Sleep modes Sleeping routers Auto-early wake-up sleep option If you have nodes that are missing sync messages and could be going out of sync with the rest of the network, enabling an early wake gives the device a better chance to hear the sync messages that are being broadcast.
Page 62: Add A New Node To An Existing Network
Sleep modes Sleeping routers 1. Set SO to 1 to enable the preferred sleep coordinator option on one of the nodes. 2. Set its SM to a synchronous sleep compatible mode (7 or 8) with its SP and ST set to a quick cycle time.
Page 63: Change Sleep Parameters
Sleep modes Sleeping routers If you do not use one of these two methods, you must wait for the network to wake up before adding the new node. Place the new node in range of the network with a sleep/wake cycle that is shorter than the wake period of the network.
Page 64: Diagnostics
Sleep modes Diagnostics When you use the default DigiMesh sleep parameters, separated subnets do not drift out of phase with each other. Subnets can drift out of phase with each other if you configure the network in one of the following ways: If you disable the non-sleep coordinator bit in the SO command on multiple devices in the network, they are eligible for the network to nominate them as a sleep coordinator.
Page 65: Missed Sync Messages Command
Sleep modes Diagnostics Missed sync messages command Use the MS command to query the number of cycles that elapsed since the device received a sync message. Sleep status API messages When you use the SO command to enable this option, a device that is in API operating mode outputs modem status frames immediately after it wakes up and prior to going to sleep.

Page 67: Networking Methods
Networking methods The MAC and PHY layers The MAC and PHY layers The PHY layer defines the physical and electrical characteristics of the network. It is responsible for managing the hardware that modulates and demodulates the RF bits. The MAC layer is responsible for sending and receiving RF frames. As part of each packet, there is a MAC layer data header that has addressing information as well as packet options.
Page 68: Make A Unicast Transmission
Make a unicast transmission Use the SH and SL commands to read this address. The form of the address is: 0x0013A2XXXXXXXXXX. The first six digits are the Digi Organizationally Unique Identifier (OUI). The broadcast address is 0x000000000000FFFF. Make a unicast transmission To transmit to a specific device in Transparent operating mode: Set DH:DL to the SH:SL of the destination device.
Page 69: Repeater/Directed Broadcast
Point to point unicast, encryption enabled 105.4 kb/s Digi made data throughput measurements setting the serial interface rate to 115200 b/s, and measuring the time to send 100,000 bytes from source to destination. During the test, no route discoveries or failures occurred.
Page 70: Digimesh Networking
Networking methods Delivery methods DigiMesh networking A mesh network is a topology in which each node in the network is connected to other nodes around it. Each node cooperates in transmitting information. Mesh networking provides these important benefits: Routing. With this technique, the message is propagated along a path by hopping from node to node until it reaches its final destination.
Page 71 Networking methods Delivery methods Related command: MR In the same manner as the repeater delivery method, DigiMesh builds on P2MP and repeater modes. In DigiMesh, broadcasts always use the repeater delivery method, but unicasts use meshing technologies. In the DigiMesh network layer, there are additional network layer ACKs and NACKs. Mesh networking allows messages to be routed through several different nodes to a final destination.
Page 72 Networking methods Delivery methods 1. The source node does not have a route to the requested destination. 2. A route fails. This happens when the source node uses up its network retries without receiving an ACK. Route discovery begins by the source node broadcasting a route request (RREQ). We call any router that receives the RREQ and is not the ultimate destination, an intermediate node.

Parameter range Default FR (Force Reset) If you issue FR while the device is in Command Mode, the reset effectively exits Command mode. Resets the device through the UART.
Page 77: Mac/Phy Commands
AT commands MAC/PHY commands MAC/PHY commands The following Binary commands are MAC/PHY commands. AF (Available Frequencies) You can query this read-only command to return a bitfield of the frequencies that are available in the device’s region of operation. This command returns a bitfield. Each bit corresponds to a physical channel.
Page 78: Mf (Minimum Frequency Count)
AT commands MAC/PHY commands more active channels enabled than required by MF, then the device uses the first MF frequencies; higher active frequencies may be unused in favor of lower ones. Exactly MF (Minimum Frequency Count) number of channels must be made available for the device to communicate on.
Page 79: Id (Network Id)
AT commands MAC/PHY commands ID (Network ID) Set or read the user network identifier. Devices must have the same network identifier to communicate with each other. Devices can only communicate with other devices that have the same network identifier and channel configured.
Page 80: Rr (Unicast Mac Retries)
AT commands Diagnostic commands RR (Unicast Mac Retries) Set or read the maximum number of MAC level packet delivery attempts for unicasts. If RR is non- zero, the sent unicast packets request an acknowledgment from the recipient. Unicast packets can be retransmitted up to RR times if the transmitting device does not receive a successful acknowledgment.
Page 81: Er (Received Error Count)
AT commands Diagnostic commands DB only indicates the signal strength of the last hop. It does not provide an accurate quality measurement for a multihop link. If the XBee-PRO 900HP RF Module has been reset and has not yet received a packet, DB reports 0. This value is volatile (the value does not persist in the device's memory after a power-up sequence).
Page 82: Tr (Transmission Failure Count)
AT commands Diagnostic commands TR (Transmission Failure Count) This count increments whenever a MAC transmission attempt exhausts all MAC retries without ever receiving a MAC acknowledgment message from the destination node. Once the number reaches 0xFFFF, it does not count further events. To reset the counter to any 16-bit value, append a hexadecimal parameter to the command.
Page 83: Network Commands
AT commands Network commands Network commands The following commands are network commands. CE (Node Messaging Options) The routing and messaging mode bit field of the device. A routing device repeats broadcasts. Indirect Messaging Coordinators do not transmit point-to- multipoint unicasts until an Indirect Messaging Poller requests them. Setting a device as an Indirect Messaging Poller causes it to regularly send polls to its Indirect Messaging Coordinator.

Page 192: Serial Communications
XBee-PRO XSC RF Module operation Serial communications Serial communications The XBee module interfaces to a host device through a CMOS-level asynchronous serial port. Through its serial port, the module can communicate with any UART voltage compatible device or through a level translator to any RS-232/485/422 device.
Page 193: Data In (Din) Buffer And Flow Control
XBee-PRO XSC RF Module operation Flow control Data In (DIN) buffer and flow control When serial data enters the device through the DIN pin (pin ), it stores the data in the DIN buffer until it can process the data. When the firmware satisfies the RB and RO parameter thresholds, the device attempts to initialize an RF transmission.
Page 194: Data Out (Do) Buffer And Flow Control
XBee-PRO XSC RF Module operation Operating modes Data Out (DO) buffer and flow control When a device receives RF data, the data enters the DOUT buffer and the device sends it out the serial port to a host device. Once the DOUT buffer reaches capacity, it loses any additional incoming RF data. In the following situations, the DOUT buffer may become full and overflow: 1.
Page 195: Transmit Mode
XBee-PRO XSC RF Module operation Operating modes Command mode (Command mode sequence issued, not available with Smart Energy software or when using the SPI port). Transmit mode When the device received the first byte of serial data from the UART in the DI buffer, the modem attempts to shift to Transmit Mode and initiate an RF connection with other modems.
Page 196 XBee-PRO XSC RF Module operation Operating modes Pin sleep Cyclic sleep For the device to transition to Sleep Mode, the module must have a non-zero SM (Sleep Mode) Parameter and one of the following must occur: The device is idle (no data transmission or reception) for a user-defined period of time. Refer to ST (Wake Time) The device asserts SLEEP (only for Pin Sleep option).
Page 197 XBee-PRO XSC RF Module operation Operating modes Once in Pin Sleep, the device de-asserts (high) CTS (pin ) , indicating that other devices should not send data to the device. The device also de-asserts (low) the TX_PWR line (pin ) when the device is in Pin Sleep mode.
Page 198: Command Mode
XBee-PRO XSC RF Module operation Operating modes Incorrect configuration (LH < SM) Length of wake-up initializer is shorter than the time interval of Cyclic Sleep. This configuration is vulnerable to the receiver waking and missing the wake-up initializer (and therefore also the accompanying payload data).
Page 199 Assert (low) the CONFIG pin and either turn the power going to the device off and back on. If using a Digi XBIB-R Interface Board, you can also hold the Data-In line low (also known as a break) while rebooting the device by pressing the reset button on the device assembly [device assembly = device mounted to an interface board.

Page 210: Network Commands
Configuration and commands Network commands Network commands The following commands are network commands. DT (Destination Address) Sets or displays the networking address of a device. The devices use three filtration layers: Vendor ID Number (ID) Channel (HP) Destination Address (DT) The DT command assigns an address to a device that enables it to communicate with only devices that have the same address.
Page 211: Ht (Time Before Wake-Up Initializer)
Configuration and commands Network commands HT (Time before Wake-up Initializer) Sets or displays the time of inactivity (no serial or RF data is sent or received) before a transmitting (TX) RF device sends a wake-up initializer. The main purpose of this command is to prevent devices from sending the Long Header with every data packet.
Page 212: Rn (Delay Slots)
Configuration and commands Network commands the Destination Address or Address Mask of the RX device for the packet to be received and sent out the RX device's DO (Data Out) pin. If the combined value does not match the Destination Address or Address Mask of the RX device, it discards the packet.
Page 213: Sy (Time Before Initialization)
Configuration and commands Network commands After transmitting a packet, the transmitting device waits to receive an ACK from a receiving device. If it does not receive the ACK in the time that RN specifies, it transmits the original packet again. The transmitting device transmits the RF packet repeatedly until it receives an ACK or until it sends the packet RR times.
Page 214: Tt (Streaming Limit)
Configuration and commands Serial interfacing commands Default 0 (Disabled - channel initialization information is sent with each RF packet.) Bytes returned TT (Streaming Limit) Sets or displays the limit on the number of bytes that a device can send before issuing a random delay. If a device is sending a continuous stream of RF data, it inserts a delay that stops its transmission and gives other devices time to transmit once it sends TT bytes of data.
Page 215: Cs (Do2 Configuration)
Configuration and commands Serial interfacing commands BD parameter to vary from the sent parameter. Sending ATBD without an associated parameter value returns the value actually stored in the device’s BD register. The following table provides the parameters sent versus the parameters stored. BD parameter sent Interface data rate S3* BD parameter...

Configuration and commands Serial interfacing commands Binary command 0x1F (31 decimal) Parameter range 0 - 4 Parameter Configuration RS-232 CTS flow control RS-485 TX enable low Static high RS-485 TX enable high Static low Default Bytes returned FL (Software Flow Control) Configures software flow control.
Page 217: Ft (Flow Control Threshold)
Configuration and commands Serial interfacing commands FT (Flow Control Threshold) Sets or displays the flow control threshold. De-assert CTS when the number of bytes specified by the FT parameter are in the DIN buffer. Re- assert CTS when less than FT - 16 bytes are in the UART receive buffer. Binary command 0x24 (36 decimal) Parameter range...
Page 218: Rb (Packetization Threshold)
Configuration and commands Serial interfacing commands Changes to the PK parameter may have a secondary effect on the RB (Packetization Threshold) parameter. RB must always be less than or equal to PK. If you change PK to a value that is less than the current value of RB, the RB value lowers to be equal to PK.
Page 219: Rt (Di2 Configuration)
Configuration and commands Diagnostic commands After a device receives a serial byte and it receives no other byte before the RO timeout, the tranmission begins. Binary command 0x21 (33 decimal) Parameter range 0 - 0xFFFF [x 200 µs] Default Bytes returned RT (DI2 Configuration) Sets or displays the behavior of the DI2/RTS/CMD line.
Page 220: Gd (Receive Good Count)
Configuration and commands Diagnostic commands Once the “Receive Error Count” reaches its maximum value (up to 0xFFFF), it remains at its maximum count value until the maximum count value is explicitly changed or you reset the device. To reset the counter to any 16-bit unsigned value, append a hexadecimal parameter to the command. This value is volatile (the value does not persist in the device's memory after a power-up sequence).
Page 221: Rp (Rssi Pwm Timer)
Configuration and commands Diagnostic commands RP (RSSI PWM Timer) Enables a pulse-width modulated (PWM) output on the CONFIG pin. We calibrate the pin to show the difference between received signal strength and the sensitivity level of the device. PWM pulses vary from zero to 95 percent.
Page 222: Rs (Rssi)
Configuration and commands Diagnostic commands Parameter range Read-only Default Bytes returned Note This command is only supported on S3B modules. RS (RSSI) Returns the signal level of the last packet received. You can use this reading to determine range characteristics of devices under various conditions of noise and distance.
Page 223: Tr (Transmission Failure Count)
Configuration and commands Diagnostic commands Binary command 0x26 (38 decimal) Parameter range 0 - 0xFFFF [read-only] Default Bytes returned TR (Transmission Failure Count) Records the number of retransmit failures. The device increments this number each time a packet is not acknowledged within the number of retransmits specified by the RR (Retries) Command.
Page 224: Sleep Commands
Configuration and commands Sleep commands Sleep commands The following commands are sleep commands. FH (Force Wakeup Initializer) Forces the device to send a wake-up initializer on the next transmission. Only use FH with cyclic sleep modes active on remote devices. You do not need to issue the WR (Write) command with FH.
Page 225: Lh (Wakeup Initializer Timer)
Configuration and commands Sleep commands LH (Wakeup Initializer Timer) Sets or displays the duration of time during which the wake-up initializer is sent. When receiving devices are in Cyclic Sleep Mode, they power-down after a period of inactivity as specified by the ST parameter and will periodically wake and listen for data transmissions.
Page 226: Sm (Sleep Mode)
Configuration and commands Sleep commands Bytes returned SM (Sleep Mode) Sets or displays the device's sleep mode settings, which configure the device to run in states that require minimal power consumption. By default, Sleep Mode is disabled and the device remains continually active. The SM command allows the device to run in a lower-power state and be configured in one of the eight settings.
Page 227 Configuration and commands Sleep commands You can only use this command if you use SM to select Cyclic Sleep or Serial Port Sleep mode settings; SM (Sleep Mode). Binary command 0x02 (2 decimal) Parameter range 0x10 – 0xFFFF [x 100 milliseconds] Default 0x64 (10 seconds) Bytes returned...

Page 229: Network Topologies
Network configurations Network topologies Network topologies The device supports three different network topologies: Point-to-point Point-to-multipoint Peer-to-peer Point-to-point networks This following section provides the RF communication type and RF mode for point-to-point networks. Definition Point-to-point means that an RF data link exists between two devices. Sample network profile (Broadcast communications) Use default values for all devices.
Page 230: Peer To Peer Networks
Network configurations Network topologies Sample network profile (Broadcast communications) Note Assume default values for all parameters that are not in this list. These profiles do not reflect addressing implementations. Base: 1. Send MY 0 to set the source address to 0x00. 2.
Page 231: Addressing
In Peer-to-peer networks, devices remain synchronized without the use of master/slave dependencies. Each device shares the roles of master and slave. Digi's peer-to-peer architecture features fast synch times (35 ms to synchronize devices) and fast cold start times (50 ms before transmission).
Page 232: Address Recognition
Network configurations Basic communications Address recognition Transmissions can be addressed to a specific device or group of devices using the DT (Destination Address) and MK (Address Mask) parameters. The transmitting device dictates whether the packet is intended for a specific device (local address) or multiple devices (global address) by comparing the packet’s DT parameter to its own MK parameter.
Page 233: Repeater Mode
Network configurations Basic communications Streaming Mode data flow Streaming Mode state diagram (TX Module) Events and processes in this mode are common to all of the other RF Modes. Note When the device is streaming data, RB and RO parameters are only observed on the first packet. After transmission begins, the TX event continues uninterrupted until the DI buffer is empty or it reaches the streaming limit (TT Command).
Page 234 Network configurations Basic communications Constraints Requires that each device have a unique MY (Source Address) parameter. System must introduce just one packet at a time to the network for transmission (256 bytes max). Each hop (H) decreases the network throughput by a factor of 1/(H+1). Additional repeaters add network redundancy without decreasing throughput.
Page 235 Network configurations Basic communications Configure remote nodes as destinations (MD = 4). This ensures that the remote node waits for the repeater traffic to subside before transmitting a response. The preceding configuration instructions reflect configuration for a Basic Broadcast Repeater system. To configure a Basic Addressed Repeater system, use the DT (Destination Address) parameter to assign unique addresses to each device in the network.
Page 236 Network configurations Basic communications of the original packet. To reduce collisions, both repeater and end node radios in a repeater network delay transmission of data shifted in the serial port allowing any repeaters within range to complete their retransmissions. The time for this delay is computed by the followinformula: Maximum Delay (ms) = L * DS DS = (((41(-100))/10)*RN)+RN+1 Where:...
Page 237: Acknowledged Mode
Network configurations Basic communications Acknowledged mode Characteristics: Reliable delivery through positive acknowledgments for each packet Throughput, latency, and jitter vary depending on the quality of the channel and the strength of the signal. Recommended use: Acknowledge Mode configuration is appropriate when reliable delivery is required between modules.
Page 238 Network configurations Basic communications The device counts each packet only once toward TT, no matter how many times the packet is retransmitted. Subsequent packets in acknowledged mode are similar to those in streaming mode, with the addition of an acknowledgment between each packet, and the possibility of retransmissions. The device sends subsequent packets without an RF initializer, because the receiving devices are already synchronized to the transmitting device from the preceding packets and they remain synchronized for the duration of the transmission event.
