Hardware Antenna options Mechanical drawings Mounting considerations Pin signals Design notes XBee/XBee-PRO S2C 802.15.
Hardware Antenna options Antenna options The ranges specified are typical for the integrated whip (1.5 dBi) and dipole (2.1 dBi) antennas. The printed circuit board (PCB) antenna option provides advantages in its form factor; however, it typically yields shorter range than the whip and dipole antenna options when transmitting outdoors. For more information, see XBee and XBee-PRO OEM RF Module Antenna Considerations Application Note.
Hardware Mounting considerations The following drawings show the XBee-PRO through-hole device. Mounting considerations We design the through-hole module to mount into a receptacle so that you do not have to solder the module when you mount it to a board. The development kits may contain RS-232 and USB interface boards that use two 20-pin receptacles to receive modules. XBee/XBee-PRO S2C 802.15.
Hardware Pin signals The following illustration shows the module mounting into the receptacle on the RS-232 interface board. Century Interconnect and Samtec manufacture the 2 x 10 pin 2 mm spacing receptacles on Digi development boards.

Minimum connections for updating firmware: VCC, GND, DIN, DOUT, RTS and DTR.
Hardware Design notes the best signal perpendicular to the direction they point, so a vertical antenna's omnidirectional radiation pattern is strongest across the horizon. Position the antennas away from metal objects whenever possible. Metal objects between the transmitter and receiver can block the radiation path or reduce the transmission distance.
Hardware Design notes Through-hole keepout Notes 1. We recommend non-metal enclosures. For metal enclosures, use an external antenna. 2. Keep metal chassis or mounting structures in the keepout area at least 2.54 cm (1 in) from the antenna. 3. Maximize the distance between the antenna and metal objects that might be mounted in the keepout area. 4. These keepout area guidelines do not apply for wire whip antennas or external RF connectors. Wire whip antennas radiate best over the center of a ground plane.
Hardware Design notes Surface-mount keepout RF pad version The RF pad is a soldered antenna connection on the surface-mount device. The RF signal travels from pin 36 on the module to the antenna through a single ended RF transmission line on the PCB. This line should have a controlled impedance of 50 Ω. For the transmission line, we recommend either a microstrip or coplanar waveguide trace on the PCB.
Hardware Design notes n The top layer has an RF trace running from pin 36 of the device to the RF pin of the RPSMA connector. The RF trace's width determines the impedance of the transmission line with relation to the ground plane. Many online tools can estimate this value, although you should consult the PCB manufacturer for the exact width. Assuming d = 0.025 in, and that the dielectric has a relative permittivity of 4.4, the width in this example will be approximately 0.045 in for a 50 Ω trace.
Hardware Design notes Number Description 4 RF connector 5 Stitch vias near the edges of the ground plane 6 Pour a solid ground plane under the RF trace on the reference layer Implementing these design suggestions helps ensure that the RF pad device performs to specifications.

Modes Serial modes Transceiver modes XBee/XBee-PRO S2C 802.15.
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/XBee-PRO S2C 802.15.4 RF Modules use Transparent operation as the default serial mode. The following modes describe how the serial port sends and receives data.
Modes Serial modes protocol that allows you to direct data on a packet basis. It can be particularly useful in large networks where you need control over the operation of the radio network or when you need to know which node a data packet is from. The device communicates UART or SPI data in packets, also known as API frames. This mode allows for structured communications with serial devices. For more information, see API mode overview.
Modes Serial modes Both of these methods temporarily set the device's baud rate to 9600 and return an OK on the UART to indicate that Command mode is active. When Command mode exits, the device returns to normal operation at the baud rate that BD is set to. Send AT commands Once the device enters Command mode, use the syntax in the following figure to send AT commands. Every AT command starts with the letters AT, which stands for "attention.
Modes Transceiver modes Make command changes permanent Send a WR (Write) command to save the changes. WR writes parameter values to non-volatile memory so that parameter modifications persist through subsequent resets. Send as RE (Restore Defaults) to wipe settings saved using WR back to their factory defaults. Note You still have to use WR to save the changes enacted with RE. Exit Command mode 1. Send CN (Exit Command mode) followed by a carriage return. or: 2.
Operation Addressing Encryption Maximum payload Networking Clear Channel Assessment (CCA) Serial interface SPI operation I/O support Sleep support Node discovery Remote configuration commands XBee/XBee-PRO S2C 802.15.
Operation Addressing Addressing Every RF data packet sent over-the-air contains a Source Address and Destination Address field in its header. The XBee/XBee-PRO S2C 802.15.4 RF Module conforms to the 802.15.4 specification and supports both short 16-bit addresses and long 64-bit addresses. A unique 64-bit IEEE source address is assigned at the factory and can be read with the SL (Serial Number Low) and SH (Serial Number High) commands. You must manually configure short addressing.
Operation Encryption 802.15.4 protocol specifies eight security modes, enumerated as shown in the following table. Level Name Length of message integrity Encrypted? check Packet length overhead 0 N/A No 0 (no check) 0 1 MIC-32 No 4 9 2 MIC-64 No 8 13 3 MIC-128 No 16 21 4 ENC Yes 0 (no check) 5 5 ENC-MIC-32 Yes 4 9 6 ENC-MIC-64 Yes 8 13 7 ENC-MIC-128 Yes 16 21 The XBee/XBee-PRO S2C 802.15.4 RF Module only supports security levels 0 and 4.
Operation Maximum payload receiving device outputs a Receive Packet (0x81) frame for received data. These same rules apply for encryption if MM is 0 or 3. This is possible because the four-byte encryption App header includes the short address of the sender and the long received address is not used for API output.
Operation Maximum payload Maximum payload summary tables The following table indicates the maximum payload when using transmit compatibility with the Legacy 802.15.4 module (S1 hardware). Encryption Enabled Disabled 95 B 100 B The following table indicates the maximum payload when using the application header and not using encryption. Increment the maximum payload in 2 bytes if you are not using the application header.
Operation n Networking The receiver may display duplicate packets. The solution is: n Set bit 0 of the C8 (802.15.4 Compatibility) parameter to 1 to enable TX compatibility mode in the XBee/XBee-PRO S2C 802.15.4 RF Module. This eliminates the transmission queue to avoid sending to multiple addresses simultaneously. It also limits the packet size to the levels of the Legacy 802.15.4 module. Networking The following table describes some common terms we use when discussing networks.
Operation Networking The default value for the MM configuration parameter is 0 which enables both the Digi header and the MAC acknowledgment. XBee retries configuration Configures the maximum number of retries the device executes in addition to the three retries provided by the 802.15.4 MAC. RR (XBee Retries) controls XBee retries configuration. It is also known as Application Retries. For each XBee retry, the 802.15.4 MAC can execute up to three retries.
Operation Networking Destination reachable Destination unreachable Retries Mac ACK Config Retries MAC App CCA failure happened TX status Retries TX status MAC App TX status MAC App Enabled 00 (Success) up to 3 per app retry up to RR value 21 3 (Network ACK Failure) RR value 02 (CCA 3 failure) RR value Disabled 00 (Success) 0 up to RR value 21 0 (Network ACK Failure) RR value 02 (CCA 3 failure) RR value Peer-to-peer networks By default, XBee/XBee-PRO S2C 802.15.
Operation Networking By default, A1 is 0, which disables association and effectively causes an end device to operate in peerto-peer mode. When bit 2 is set, the end device associates to a coordinator. This is done by sending out an active scan to detect beacons from nearby networks. The active scan selects one channel and transmits a Beacon Request command to the broadcast address and the broadcast PAN ID. It then listens on that channel for beacons from any coordinator operating on that channel.
Operation Networking If A2 bit 1 is set, the coordinator will issue an energy scan, similar to the active scan. It will listen on each channel specified in the SC parameter for the time indicated by the SD parameter. After the scan is complete, the channel with the least energy is selected to form the new network. If A2 bit 1 is clear, then no energy scan is performed and the CH parameter is used to select the channel of the new network.
Operation Networking enabled. On demand queries occur when the AI command is issued, which can occur in Command mode, in API mode, or as a remote command. Device Status Messages Not all device status messages are related with association, but for completeness all device status types reported by XBee/XBee-PRO S2C 802.15.4 RF Module are listed in the following table. Type Meaning 0x00 Hardware reset. 0x01 Watchdog reset. 0x02 End device successfully associated with a coordinator.
Operation Clear Channel Assessment (CCA) Sleep conditions Since instructions stop executing while the device is sleeping, it is important to avoid sleeping when the device has work to do. For example, the device will not sleep if any of the following are true: 1. The device is operating in command mode, or in the process of getting into command mode with the +++ sequence. 2. The device is processing AT commands from API mode 3. The device is processing remote AT commands 4.
Operation Serial interface parameter) defines the energy level that it takes to block a transmission attempt. For example, if CCA is set to the default value of 0x2C (which is interpreted as -44 dBm) then energy detected above the 44 dBm level (for example -40 dBm) temporarily blocks a transmission attempt. But if the energy level is less than that (for example -50 dBm), the transmission is not blocked. The intent of this feature is to prevent simultaneous transmissions on the same channel.
Operation Serial interface Serial receive buffer When serial data enters the device through the DIN pin (or the MOSI pin), it stores the data in the serial receive buffer until the device can process it. Under certain conditions, the device may not be able to process data in the serial receive buffer immediately. If large amounts of serial data are sent to the device such that the serial receive buffer would overflow, then it discards new data.
Operation Serial interface Flow control The XBee/XBee-PRO S2C 802.15.4 RF Module maintains buffers to collect serial and RF data that it receives. The serial receive buffer collects incoming serial characters and holds them until the device can process them. The serial transmit buffer collects the data it receives via the RF link until it transmits that data out the serial port. The following figure shows the process of device buffers collecting received serial data.
Operation SPI operation If the device sends data out the UART when RTS is de-asserted (set high) the device could send up to five characters out the UART port after RTS is de-asserted. Cases in which the DO buffer may become full, resulting in dropped RF packets: 1. If the RF data rate is set higher than the interface data rate of the device, the device may receive data faster than it can send the data to the host.
Operation SPI operation XBee device must be externally tri-stated when SPI_SSEL is de-asserted to prevent multiple devices from driving SPI_MISO. SPI_MOSI: The SPI master outputs data on this line at the SPI_CLK rate after it selects the desired slave. When you configure the device for SPI operations, this pin is an input. SPI_SCLK: The SPI master outputs a clock on this pin, and the rate must not exceed the maximum allowed, 5 Mb/s. This signal clocks data transfers on MOSI and MISO.
Operation I/O support Slave mode characteristics In slave mode, the following apply: n SPI Clock rates up to 5 MHz (5 Mb/s) are possible. n Data is MSB first. n It uses Frame Format Mode 0. This means CPOL= 0 (idle clock is low) and CPHA = 0 (data is sampled on the clock’s leading edge). The picture below diagrams Mode 0. n The SPI port is setup for API mode and is equivalent to AP = 1. The following picture shows the frame format for SPI communications.
Operation I/O support Digital I/O line support Digital I/O is available on pins D0 through D8. Each of these pins may be configured as 3, 4, or 5 with the following meanings: n 3 is digital input n 4 is digital output low n 5 is digital output high Pins D0 through D8 are available for digital input, but only D0 through D7 are available for digital output.
Operation I/O support In this example, note the following: 83 indicates RX Packet: 16-bit Address I/O frame (0x83). 00 00 indicates 16-bit source address. 00 indicates RSSI (does not apply). 00 indicates options. 01 indicates the number of samples. 03 3E mask to indicate which lines are sampled (A0, D8, D5, D4, D3, D2, and D1). 01 2A digital sample that indicates that D8 is high, D5 is high, D4 is low, D3 is high, D2 is low, and D1 is high.
Operation I/O support Multiple samples per packet The IT parameter specifies how many I/O samples can be transmitted in a single OTA packet. Any single-byte value (0 - 0xFF) is accepted for input. However, the value is adjusted downward based on how many I/O samples can fit into a maximum size packet; see Maximum payload. A query of the IT parameter after changes are applied tells how many I/O samples actually occur.
Operation I/O support Although samples may be taken every millisecond, IR*IT should be at least 20 milliseconds. This allows time for OTA transmission and output on the serial port of the receiving module. Destination node On the destination node, the IU parameter enables the serial port to output I/O samples it receives. IU is set to 1 by default. If IU is set and the destination node is not in Command mode, it displays samples it receives on its serial port in API format.
Operation I/O support Wakeup I/O sampling Bit 2 of the SO parameter specifies whether or not the device automatically samples the ADC/DIO lines on wakeup. On the receiving side the I/O sample may go to the I/O pins, the serial port, both, or neither based on the settings of the IA (I/O Input Address) and IU (I/O Output Enable) parameters. For more information, see SO (Sleep Options), IA (I/O Input Address), and IU (I/O Output Enable).
Operation Sleep support I/O line passing details The same message is received for both I/O sampling and for I/O line passing. But I/O line passing only occurs if IA matches the short or long address of the sending node or if IA is 0xFFFF to match a sample from any node. The default value of IA is 0xFFFFFFFF, which prevents I/O line passing from occurring on the node because no node has that address. Additionally, the receiving device must have a matching value for output.
Operation Sleep support Sleep mode Description SM 0 No sleep SM 1 Pin sleep SM 4 Cyclic sleep SM 5 Cyclic sleep with pin wake-up Pin Sleep mode (SM = 1) Pin Sleep mode minimizes quiescent power (power consumed when in a state of rest or inactivity). This mode is voltage level-activated; when Sleep_RQ (pin 9 for through-hole, pin 10 for surface-mount) is asserted, the device finishes any transmit, receive or association activities, enters Idle mode, and then enters a state of sleep.
Operation Sleep support n SP (Cyclic Sleep Period) n DP (Disassociated Cyclic Sleep Period) Sleep current The following table shows the sleep current during the XBee/XBee-PRO S2C 802.15.4 RF Module sleep modes.
Operation Node discovery Indirect transmissions can only occur on a Coordinator. Thus, if all nodes in a network are End Devices, only direct transmissions occurs. Indirect transmissions are useful to ensure packet delivery to a sleeping node. The Coordinator currently is able to retain up to five indirect messages. Direct transmission A Coordinator can be configured to use only direct transmission by setting the SP (Cyclic Sleep Period) parameter to 0.
Operation Node discovery When the node discovery command is issued in AT command mode, all other AT commands are inhibited until the node discovery command times out, as specified by the NT parameter. After the timeout, an extra CRLF is output to the terminal window, indicating that new AT commands can be entered. This is the behavior whether or not there were any nodes that responded to the broadcast.
Operation Remote configuration commands DL at 0). If the responding node has a long address (MY is FFFE), then DH/DL are set to the SH/SL of the responding node. Remote configuration commands The API firmware has provisions to send configuration commands to remote devices using the Remote AT Command Request frame (0x17); see Remote AT Command Request frame - 0x17. You can use this frame to send commands to a remote device to read or set command parameters.
AT commands Special commands Networking and security commands RF interfacing commands Sleep commands Serial interfacing commands I/O settings commands I/O line passing commands Diagnostic commands Command mode options XBee/XBee-PRO S2C 802.15.
AT commands Special commands Special commands The following commands are special commands. WR (Write) Writes parameter values to non-volatile memory so that parameter modifications persist through subsequent resets. Writing parameters to non-volatile memory does not apply the changes immediately. However, since the device uses non-volatile memory to determine initial configuration following reset, the written parameters are applied following a reset.
AT commands Networking and security commands Parameter range 0-3 Bit field: Bit Meaning 01 Setting Description TX 0 compatibility Transmissions are optimized as follows: 1. Maximum transmission size is affected by multiple factors (MM, MY, DH, DL, and EE). See Maximum payload rules. In the best case, with no app header, short source and destination addresses, and no encryption, the maximum transmission size is 116 bytes. 2.
AT commands Networking and security commands Default 0 CH (Operating Channel) Set or read the operating channel devices used to transmit and receive data. The channel is one of three addressing configurations available to the device. The other configurations are the PAN ID (ID command) and destination addresses (DL and DH commands). In order for devices to communicate with each other, they must share the same channel number.
AT commands Networking and security commands Default 0 DL (Destination Address Low) Set or display the lower 32 bits of the 64-bit destination address. When you combine DH with DL, it defines the destination address that the device uses for transmissions in Transparent mode. The destination address is also used for I/O sampling in both Transparent and API modes. 0x000000000000FFFF is the broadcast address. It is also used as the polling address when the device functions as end device.
AT commands Networking and security commands Default Set in the factory MM (MAC Mode) The MM command is used to set and read the MAC Mode value. The MM command disables/enables the use of a Digi header contained in the 802.15.4 RF packet. By default (MM = 0), Digi Mode is enabled and the module adds an extra header to the data portion of the 802.15.4 packet.
AT commands Networking and security commands Parameter range 0-6 Default 0 RN (Random Delay Slots) Sets or displays the minimum value of the back-off exponent in the CSMA-CA algorithm. The Carrier Sense Multiple Access - Collision Avoidance (CSMA-CA) algorithm was engineered for collision avoidance(random delays are inserted to prevent data loss caused by data collisions. If RN = 0, there is no delay between a request to transmit and the first iteration of CSMA-CA.
AT commands Networking and security commands 4 bytes for Lower Long Address 1 byte for the signal strength in -dBm (two's compliment representation) NULL-terminated string for NI (Node Identifier) value (maximum 20 bytes without NULL terminator) Each device that responds to the request will generate a separate AT Command Response frame 0x88. Broadcast an ND command to the network.
AT commands Networking and security commands Default 0x0 DN (Discover Node) Resolves an NI (Node identifier) string to a physical address (case sensitive). The following events occur after DN discovers the destination node: When DN is sent in Command mode : 1. The device sets DL and DH to the address of the device with the matching NI string. The address selected (either 16-bit short address or 64-bit extended address) is chosen based on the destination device's MY command configuration. 2.
AT commands Networking and security commands Default 0 SC (Scan Channels) Sets or displays the list of channels to scan for all Active and Energy Scans as a bit field. This affects scans initiated in the AS (Active Scan) and ED (Energy Scan) commands in Command mode and during End Device Association and Coordinator startup.
AT commands Networking and security commands PANs. If you set the ReassignChannel option, SD determines how long the coordinator performs an Energy Scan to determine which channel it will operate on. End Device: Duration of Active Scan during Association. In a Beacon system, set SD=BE of the coordinator. SD must be set at least to the highest BE parameter of any Beaconing Coordinator with which an end device or coordinator wants to discover.
AT commands Networking and security commands Bit Meaning Setting Description 0 0 Only associates with Coordinator operating on PAN ID that matches device ID. 1 May associate with Coordinator operating on any PAN ID. 0 Only associates with Coordinator operating on matching CH channel setting. 1 May associate with Coordinator operating on any channel. 0 Device will not attempt association. 1 Device attempts association until success.
AT commands Networking and security commands The binary equivalent of the default value (0x06) is 00000110. ‘Bit 0’ is the last digit of the sequence. Default 0 AI (Association Indication) Reads the Association status code to monitor association progress. The following table provides the status codes and their meanings. Status code Meaning 0x00 Coordinator successfully started, End device successfully associated, or operating in peer to peer mode where no association is needed.
AT commands Networking and security commands Parameter range N/A Default N/A AS (Active Scan) Sends a Beacon Request to a Broadcast address (0xFFFF) and Broadcast PAN (0xFFFF) on every channel in SC. SD determines the amount of time the device listens for Beacons on each channel. A PanDescriptor is created and returned for every Beacon received from the scan.
AT commands Networking and security commands Parameter range 0-6 Default N/A ED (Energy Detect) Starts an energy detect scan. This command accepts an argument to specify the time in milliseconds to scan all channels. The device loops through all the available channels until the time elapses. It returns the maximal energy on each channel, a comma follows each value, and the list ends with a carriage return. The values returned reflect the energy level that ED detects in -dBm units.
AT commands Networking and security commands KY (AES Encryption Key) Sets the 128-bit network security key value that the device uses for encryption and decryption. This command is write-only. If you attempt to read KY, the device returns an OK status. Set this command parameter the same on all devices in a network. The entire payload of the packet is encrypted using the key and the CRC is computed across the ciphertext.
AT commands RF interfacing commands RF interfacing commands The following AT commands are RF interfacing commands. PL (TX Power Level) Sets or displays the power level at which the device transmits conducted power. Power levels are approximate. For XBee-PRO, PL= 4 is calibrated and the remaining power levels are approximate. The device recalibrates its power setting every 15 seconds based on factory calibration settings and the current temperature.

Operate in API mode API mode overview API mode overview As an alternative to Transparent operating mode, you can use API operating mode. API mode provides a structured interface where data is communicated through the serial interface in organized packets and in a determined order. This enables you to establish complex communication between devices without having to define your own protocol.
Operate in API mode API frame specifications When operating in API 2, if an unescaped 0x7E byte is observed, it is treated as the start of a new API frame and all data received prior to this delimiter is silently discarded. For more information on using this API mode, refer to the following knowledge base article: http://knowledge.digi.
Operate in API mode API frame specifications Frame data Start delimiter Length Frame type 1 2 3 4 0x7E MSB LSB API frame type Checksum Data 5 6 7 8 9 ... n Data n+1 Single byte n Frame type is the API frame type identifier. It determines the type of API frame and indicates how the Data field organizes the information. n Data contains the data itself. This information and its order depend on the what type of frame that the Frame type field defines.

Migrate from XBee through-hole to surface-mount devices We design the XBee surface-mount and through-hole devices to be compatible with each other and offer the same basic feature set. The surface-mount form factor has more I/O pins. Because the XBee device was originally offered in only the through-hole form factor, we offer this section to help you migrate from the through-hole to the surface-mount form factor.

Each footprint requires different mounting techniques.
Migrate from XBee through-hole to surface-mount devices Mount the devices The round holes in the diagram are for the TH design, and the semi-oval pads are for the SMT design. Pin 1 of the TH design is lined up with pad 1 of the SMT design, but the pins are actually offset by one pad; see Pin mapping. By using diagonal traces to connect the appropriate pins, the layout will work for both devices. PCB design and manufacturing contains information on attaching the SMT device.

PCB design and manufacturing The XBee/XBee-PRO S2C 802.15.4 RF Module is designed for surface-mount on the OEM PCB. It has castellated pads to allow for easy solder attach inspection. The pads are all located on the edge of the module, so there are no hidden solder joints on these modules.

PCB design and manufacturing Recommended footprint and keepout While the underside of the module is mostly coated with solder resist, we recommend that the copper layer directly below the module be left open to avoid unintended contacts. Copper or vias must not interfere with the three exposed RF test points on the bottom of the module (see below).
PCB design and manufacturing Flux and cleaning Flux and cleaning We recommend that you use a “no clean” solder paste in assembling these devices. This eliminates the clean step and ensures that you do not leave unwanted residual flux under the device where it is difficult to remove. In addition: n Cleaning with liquids can result in liquid remaining under the device or in the gap between the device and the host PCB. This can lead to unintended connections between pads.
PCB design and manufacturing Rework following information is given as a guideline in such cases to increase the chances of success during rework, though the warranty is still voided. The module may be removed from the OEM PCB by the use of a hot air rework station, or hot plate. Care should be taken not to overheat the module. During rework, the module temperature may rise above its internal solder melting point and care should be taken not to dislodge internal components from their intended positions.
