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. 2.1.1.

Serial Data Data enters the XBee module through the DI pin as an asynchronous serial signal. The signal should idle high when no data is being transmitted. The UART performs tasks, such as timing and parity checking, that are needed for data communications. Serial communication consists of two UARTs, one being the XBee's and the other being the Microcontroller's, configured with compatible parameters (baud rate, parity, start bits, stop bits, data bits) to have successful communication. Each data packet consists of a start bit

(low), 8 data bits (least significant bit first) and a stop bit (high). The following figure illustrates the serial bit pattern of data passing through the module. Figure202.

InternalDataFlowDiagram(Thefivemostcommonlyusedpinsignalsshown.) DI (Data In) Buffer and Flow Control When serial data enters the XBee module through the DI Pin, then the data is stored in the DI Buffer until it can be transmitted. When the RO parameter threshold is satisfied (refer to Transmit Mode and Command Descriptions sections for more information), the module attempts to initialize an RF connection. If the module is already receiving RF data, the serial data is stored in the module's DI Buffer. If the DI buffer becomes full, hardware or software flow control must be implemented in order to prevent overflow

(loss of data between the host and XBee OEM RF Module). How to eliminate the need for flow control:

Send messages that are smaller than the DI buffer size, which is generally around 1,000 bytes. Interface at a lower baud rate (BD parameter) than the fixed RF data rate with the Retries functionality (RR parameter) disabled. Two cases in which the DI Buffer may become full and possibly overflow:

If the serial interface data rate is set higher than the RF data rate of the module, the module will receive data from the host faster than it can transmit the data over-the-air. If the module is receiving a continuous stream of data, monitoring data on a network, or awaiting acknowledgments for Retries functionality, any serial data that arrives on the DI pin is placed in the DI Buffer. The data in the DI buffer will be transmitted over-the-air when the module no longer detects RF data in the network. Hardware Flow Control (CTS). When the DI buffer is 65 bytes away from being full; by default, the module de-asserts (high) CTS to signal to the host device to stop sending data [refer to FT

(Flow Control Threshold) and CS (DO2 Configuration) Commands]. CTS is re-asserted after the DI Buffer has 34 bytes of memory available. Software Flow Control (XON). XON/XOFF software flow control can be enabled using the FL

(Software Flow Control) command. DO (Data Out) Buffer and Flow Control When RF data is received, the data enters the DO buffer and is then sent out the serial port to a host device. Once the DO Buffer reaches capacity, any additional incoming RF data is lost. Two cases in which the DO Buffer may become full and possibly overflow:

If the RF data rate is higher than the set interface data rate of the module, the module will receive data from the transmitting module faster than it can send the data to the host. If the host does not allow the RF module to send data out of the DO buffer because of hard-

ware or software flow control. Hardware Flow Control (RTS). If RTS is enabled for flow control (RT Parameter = 2), data will not be sent out the DO Buffer as long as RTS (pin 16) is de-asserted. Software Flow Control (XOFF). XON/XOFF software flow control can be enabled using the FL

(Software Flow Control) Command. This option only works with ASCII data. 2011DigiInternational,Inc. 10 XBeePROXSCOEMRFModules 2.2. Modes of Operation XBee-PRO XSC RF Modules operate in five modes. Figure204. ModesofOperation 2.2.1. Idle Mode When not receiving or transmitting data, the RF module is in Idle Mode. The module shifts into the other modes of operation under the following conditions:

Transmit Mode (Serial data is received in the DI Buffer) Receive Mode (Valid RF data is received through the antenna) Sleep Mode (Sleep Mode condition is met) Command Mode (Command Mode Sequence is issued) 2.2.2. Transmit Mode When the first byte of serial data is received from the UART in the DI buffer, the modem attempts to shift to Transmit Mode and initiate an RF connection with other modems. After transmission is complete, the modem returns to Idle Mode. RF transmission begins after either of the following criteria is met:

1. RB bytes have been received in the DI buffer and are pending for RF transmission [refer to RB

(Packetization Threshold) command, p34].

- The RB parameter may be set to any value between 1 and the RF packet size (PK), inclusive. When RB = 0, the packetization threshold is ignored. 2. At least one character has been received in the DI buffer (pending for RF transmission) and RO time has been observed on the UART [refer to RO (Packetization Timeout) command].

- The timeout can be disabled by setting RO to zero. In this case, transmission will begin after RB bytes have been received in the DI buffer. Note: RF reception must complete before the modem is able to enter into Transmit Mode. After either RB or RO conditions are met, the modem then initializes a communications channel.

[Channel initialization is the process of sending an RF initializer that synchronizes receiving modems with the transmitting modem. During channel initialization, incoming serial data accumulates in the DI buffer.]

Serial data in the DI buffer is grouped into RF packets [refer to PK (RF Packet Size)]; converted to RF data; then transmitted over-the-air until the DI buffer is empty. RF data, which includes the payload data, follows the RF initializer. The payload includes up to the maximum packet size (PK Command) bytes. As the transmitting modem nears the end of the transmission, it inspects the DI buffer to see if more data exists to be transmitted. This could be the case if more than PK bytes were originally pending in the DI buffer or if more bytes arrived from the UART after the transmission began. If more data is pending, the transmitting modem assembles a subsequent packet for transmission. 2011DigiInternational,Inc. 11 XBeePROXSCOEMRFModules RF Packet The RF packet is the sequence of data used for communicating information between MaxStream Modems. An RF Packet consists of an RF Initializer and RF Data. When streaming multiple RF packets, the RF Initializer is only sent in front of the first packet. RF Initializer An RF initializer is sent each time a new connection sequence begins. The RF initializer contains channel information that notifies receiving modems of information such as the hopping pattern used by the transmitting modem. The first transmission always sends an RF initializer. An RF initializer can be of various lengths depending on the amount of time determined to be required to prepare a receiving modem. For example, a wake-up initializer is a type of RF initial-

izer used to wake remote modems from Sleep Mode (Refer to the FH, LH, HT and SM Com-

mands for more information). The length of the wake-up initializer should be longer than the length of time remote modems are in cyclic sleep. 2011DigiInternational,Inc. 12 XBeePROXSCOEMRFModules Header The header contains network addressing information that filters incoming RF data. The receiv-

ing modem checks for a matching Hopping Channel (HP parameter), Vendor Identification Num-

ber (ID parameter) and Destination Address (DT parameter). Data that does not pass through all three network filter layers is discarded. CRC (Cyclic Redundancy Check) To verify data integrity and provide built-in error checking, a 16-bit CRC (Cyclic Redundancy Check) is computed for the transmitted data and attached to the end of each RF packet. On the receiving end, the receiving modem computes the CRC on all incoming RF data. Received data that has an invalid CRC is discarded. Receive Mode If a module detects RF data while operating in Idle Mode, the module transitions into Receive Mode to start receiving RF packets. Figure205. ReceptionofRFData After a packet is received, the module checks the CRC (cyclic redundancy check) to ensure that the data was transmitted without error. If the CRC data bits on the incoming packet are invalid, the packet is discarded. If the CRC is valid, the packet proceeds to the DO Buffer. The module returns to Idle Mode after valid RF data is no longer detected or after an error is detected in the received RF data. If serial data is stored in the DI buffer while the module is in Receive Mode, the serial data will be transmitted after the module is finished receiving data and returns to Idle Mode. 2.2.3. Sleep Mode Sleep Modes enable the XBee module to operate at minimal power consumption when not in use. The following Sleep Mode options are available:

Pin Sleep Cyclic Sleep For the module to transition into Sleep Mode, the module must have a non-zero SM (Sleep Mode) Parameter and one of the following must occur:

The module is idle (no data transmission or reception) for a user-defined period of time [Refer to the ST (Time before Sleep) Command]. SLEEP is asserted (only for Pin Sleep option). In Sleep Mode, the module will not transmit or receive data until the module first transitions to Idle Mode. All Sleep Modes are enabled and disabled using SM Command. Transitions into and out of Sleep Modes are triggered by various events as shown in the table below. 2011DigiInternational,Inc. 13 XBeePROXSCOEMRFModules Table201.

Note: Module can be forced into Idle Mode if PW (Pin Wake-up) Command is enabled. Microcontroller can shut down and wake modules by asserting (high) SLEEP (pin 9). Note: The module will complete a transmission or reception before activating Pin Sleep. Automatic transition to Sleep Mode occurs in cycles as defined by the SM (Sleep Mode) Command. Note: The cyclic sleep time interval must be shorter than the Wake-up Initializer Timer

(set by LH Command). Pin Sleep (SM = 1) In order to achieve this state, SLEEP pin must be asserted (high). The module remains in Pin Sleep until the SLEEP pin is de-asserted. After enabling Pin Sleep, the SLEEP pin controls whether the XBee module is active or in Sleep Mode. When SLEEP is de-asserted (low), the module is fully operational. When SLEEP is asserted

(high), the module transitions to Sleep Mode and remains in its lowest power-consuming state until the SLEEP pin is de-asserted. SLEEP is only active if the module is setup to operate in this mode; otherwise the pin is ignored. Once in Pin Sleep Mode, CTS is de-asserted (high), indicating that data should not be sent to the module. The PWR pin is also de-asserted (low) when the module is in Pin Sleep Mode. 76 A when sleeping 2.5uA when sleeping Note: The module will complete a transmission or reception before activating Pin Sleep. Cyclic Sleep (SM = 3-8) Cyclic Sleep is the Sleep Mode in which the XBee module enters into a low-power state and awakens periodically to determine if any transmissions are being sent. When Cyclic Sleep settings are enabled, the XBee module goes into Sleep Mode after a user-

defined period of inactivity (no transmission or reception on the RF channel). The user-defined period is determined by ST (Time before Sleep) Command. While the module is in Cyclic Sleep Mode, CTS is de-asserted (high) to indicate that data should not be sent to the module during this time. When the module awakens to listen for data, CTS is asserted and any data received on the DI Pin is transmitted. The PWR pin is also de-asserted (low) when the module is in Cyclic Sleep Mode. The module remains in Sleep Mode for a user-defined period of time ranging from 0.5 seconds to 16 seconds (SM Parameters 3 through 8). After this interval of time, the module returns to Idle Mode and listens for a valid data packet for 100 ms. If the module does not detect valid data (on any frequency), the module returns to Sleep Mode. If valid data is detected, the module transitions into Receive Mode and receives incoming RF packets. The module then returns to Sleep Mode after a Period of inactivity that is determined by ST Time before Sleep Command. The module can also be configured to wake from cyclic sleep when SLEEP (pin 9) is de-asserted

(low). To configure a module to operate in this manner, PW (Pin Wake-up) Command must be issued. Once SLEEP is de-asserted, the module is forced into Idle Mode and can begin transmitting or receiving data. It remains active until no data is detected for the period of time specified by the ST Command, at which point it resumes its low-power cyclic state. Note: The cyclic interval time defined by SM (Sleep Mode) Command must be shorter than the interval time defined by LH (Wake-up Initializer Timer). For example: If SM=4 (Cyclic 1.0 second sleep), the LH Parameter should equal 0x0B ("1.1"

seconds). With these parameters set, there is no risk of the receiving module being asleep for the duration of wake-up initializer transmission. Cyclic Scanning explains in further detail the relationship between Cyclic Sleep and Wake-up Initializer Timer 2011DigiInternational,Inc. 14 XBeePROXSCOEMRFModules Cyclic Scanning. Each RF transmission consists of an RF Initializer and payload. The wake-up initializer contains initialization information and all receiving modules must wake during the wake-

up initializer portion of data transmission in order to be synchronized with the transmitting module and receive the data. Figure206.

Command Mode To modify or read module parameters, the module must first enter into Command Mode, the state in which received characters on the UART are interpreted as commands. Two command types are avail-

able for programming the module:

AT Commands Binary Commands For modified parameter values to persist in the module registry, changes must be saved to non-vola-

tile memory using WR (Write) Command. Otherwise, parameters are restored to previously saved val-

ues after the module is powered off and then on again. AT Commands To Enter AT Command Mode:

Send the 3-character command sequence +++ and observe guard times before and after the command characters. [refer to Default AT Command Mode Sequence below.] The Termi-

nal tab (or other serial communications software) of the X-CTU Software can be used to enter the sequence.

[OR]

Assert (low) the CONFIG pin and either turn the power going to the module off and back on.

(If using a Digi XBIB-R Interface Board, the same result can be achieved by holding the Data-

In line low (also known as a break) while rebooting the module by pressing the reset button on the module assembly [module assembly = module mounted to an interface board]). 2011DigiInternational,Inc. 15 XBeePROXSCOEMRFModules Default AT Command Mode Sequence (for transition to Command Mode):

No characters sent for one second [refer to the BT (Guard Time Before) Command]

Input three plus characters (+++) within one second

[refer to the CC (Command Sequence Character) Command.]

No characters sent for one second [refer to the AT (Guard Time After) Command.]

To Send AT Commands:

Send AT commands and parameters using the syntax shown below. Figure28.SyntaxforsendingATCommands To read a parameter value stored in the module register, leave the parameter field blank. The preceding example would change the modules Destination Address to 0x1F. To store the new value to non-volatile (long term) memory, the Write (ATWR) command must subsequently be sent before powering off the module. System Response. When a command is sent to the module, the module will parse and execute the command. Upon successful execution of a command, the module returns an OK message. If execution of a command results in an error, the module returns an ERROR message. To Exit AT Command Mode:

If no valid AT Commands are received within the time specified by CT (Command Mode Time-

out) Command, the module automatically returns to Idle Mode.

[OR]

Send ATCN (Exit Command Mode) Command. For an example of programming the RF module using AT Commands and descriptions of each config-

urable parameter, refer to the RF Module Configuration chapter. Binary Commands Sending and receiving parameter values using binary commands is the fastest way to change operating parameters of the module. Binary commands are used most often to sample signal strength (RS parameter) and/or error counts; or to change module addresses and channels for polling systems when a quick response is necessary. Since the sending and receiving of parameter values takes place through the same data path as 'live' data (received RF payload), follow the CTS pin as outlined in Figure 2-012 to distinguish between the two types of data (commands vs 'live'

data). Common questions regarding the use of binary commands:

What are the implications of asserting CMD while live data is being sent or received?

After sending serial data, is there a minimum time delay before CMD can be asserted?

Is a time delay required after CMD is de-asserted before payload data can be sent?

How to discern between live data and data received in response to a command?

CMD (pin 16) must be asserted in order to send binary commands to the module. The CMD pin can be asserted to recognize binary commands anytime during the transmission or reception of data. The status of the CMD signal is only checked at the end of the stop bit as the byte is shifted into the serial port. The application does not allow control over when data is received, except by waiting for dead time between bursts of communication. If the command is sent in the middle of a stream of payload data to be transmitted, the command will essentially be executed in the order it is received. If the radio is continuously receiving data, the radio will wait for a break in the received data before executing the command. The CTS signal will frame the response coming from the binary command request [Figure 2-09]. 2011DigiInternational,Inc. 16 XBeePROXSCOEMRFModules A minimum time delay of 100 s (after the stop bit of the command byte has been sent) must be observed before pin 5 can be de-asserted. The command executes after all parameters associated with the command have been sent. If all parameters are not received within 0.5 seconds, the module aborts the command and returns to Idle Mode. Note: Binary commands that return only one parameter byte must also be written with two parameter bytes, 0-padded, LSB first. Refer to Programming Examples section [pXX] for a binary programming example. Commands can be queried for their current value by sending the command logically ORed (bit-

wise) with the value 0x80 (hexadecimal) with CMD asserted. When the binary value is sent (with no parameters), the current value of the command parameter is sent back through the DO pin. Figure209. BinaryCommandWritethenRead Signal#4isCMD(pin16) Signal#1istheDIN(pin3)signal totheradio Signal#2istheDOUT(pin2)signal fromtheradio Signal#3isCTS(pin12) In this graph, a value was written to a register and then read out to verify it. While not in the middle of other received data, note that the CTS signal outlines the data response out of the module. IMPORTANT: For the XBee module to recognize a binary command, the RT (DI2 Configuration) param-

eter must be set to one. If binary programming is not enabled RT = 0 or 2, the module will not recog-

nize that the CMD pin is asserted and therefore will not recognize the data as binary commands. 2011DigiInternational,Inc. 17 XBeePROXSCOEMRFModules 3.RFModuleConfiguration 3.1.

To Send AT Commands (Using the Terminal tab of the X-CTU Software) Example: Utilize the 'Terminal' tab of the X-CTU Software to change the module's DT (Destina-

tion Address) parameter and save the new address to non-volatile memory. This example requires the installation of Digis X-CTU Software and a serial connection to a PC. Select the Terminal tab of the X-CTU Software and enter the following command lines:

Method 1 (One line per command) Send AT Command

*CommandsonlysupportedonS3Bhardware. 3.3. Command Descriptions Commands in this section are listed alphabetically. Command categories are designated between the < > symbols that follow each command title. Modules expect numerical values in hexadecimal and those values are designated by a 0x prefix. Modules operating within the same network should contain the same firmware platform to ensure the same AT Command parameters are supported. AM (Auto-set MY) Command Command Summary AT Command: ATAM Binary Command: 0x3A (58 decimal) This command is only supported on S3B modules. Description

<Networking & Security> AM Command is used to automatically set the MY

(Source Address) parameter from the factory-set module serial number. The address is formed with bits 29, 28 and 13-0 of the serial number (in that order). AT (Guard Time After) Command Command Summary AT Command: ATAT Binary Command: 0x05 (5 decimal) Parameter Range:0x02 0xFFFF

[x 100 milliseconds]

Number of bytes returned: 2 Default Parameter Value: 0x0A (10 decimal) Related Commands: BT (Guard Time Before), CC (Command Sequence Character) Description

<Command Mode Options> AT Command is used to set the time-of-

silence that follows the command sequence character (CC Command). By default, AT Command Mode will activate after one second of silence. Refer to the AT Commands section [p] to view the default AT Command Mode Sequence. 2011DigiInternational,Inc. 20 XBeePROXSCOEMRFModules BD (Interface Data Rate) Command Command Summary AT Command: ATBD Binary Command: 0x15 (21 decimal) Parameter Range (Standard baud rates): 0 6

<Serial Interfacing> BD Command allows the user to adjust the UART interface data rate and thus modify the rate at which serial data is sent to the module. The new baud rate does not take effect until the CN (Exit AT Command Mode) Command is issued. The RF data rate is not affected by the BD Command. Although most applications will only require one of the seven standard baud rates, non-standard baud rates are also supported. Note: If the serial data rate is set to exceed the fixed RF data rate of the module, flow control may need to be implemented as described in the Pin Signals and Flow Control sections of this manual. Non-standard Interface Data Rates: When parameter values outside the range of standard baud rates are sent, the closest interface data rate represented by the number is stored in the BD register. For example, a rate of 19200 bps can be set by sending the following command line ATBD4B00. NOTE: When using X-CTU Software, non-standard interface data rates can only be set and read using the X-CTU Terminal tab. Non-

standard rates are not accessible through the Modem Configuration tab. When the BD command is sent with a non-standard interface data rate, the UART will adjust to accommodate the requested interface rate. In most cases, the clock resolution will cause the stored BD parameter to vary from the parameter that was sent

(refer to the table below). Reading the BD command (send ATBD command without an associated parameter value) will return the value that was actually stored to the BD register. Table302.

Default Parameter Value: 0xC8 (200 decimal, 20 seconds) Number of bytes returned: 2 Description

<Command Mode Options> CT Command sets the amount of time before AT Command Mode terminates automatically. After a CT time of inactivity, the module exits AT Command Mode and returns to Idle Mode. AT Command Mode can also be exited manually using CN (Exit AT Command Mode) Command. DB (RSSI in dBm) Command Command Summary AT Command: ATDB Binary Command: Not available Parameter Range:00x00 to 0x70

[read-only]

Number of bytes returned: returned: 1 Related Commands: RS (RSSI Level) Description

<Diagnostics> DB command returns the signal level of the last packet received in dBm. This reading is useful for determining range characteristics of the Modules under various conditions of noise and distance. Once the command is issued, the module will return the value in dBm. 0x32 (50d) = -50 dBm (strong signal), and 0x64 (100d) = -100 dBm (weak signal). DT (Destination Address) Command Command Summary AT Command: ATDT Binary Command: 0x00 Parameter Range:0 0xFFFF Default Parameter Value: 0 Number of bytes returned: 2 Related Commands: HP (Hopping Channel), ID (Module VID), MK (Address Mask) Description

<Networking> DT Command is used to set the networking address of a Module. Modules use three network layers Vendor Identification Number (ATID), Channels (ATHP), and Destination Addresses (ATDT). DT Command assigns an address to a module that enables it to communicate only with other modules having the same addresses. All modules that share the same Destination Address can communicate freely with each other. Modules in the same network with a different Destination Address (than that of the transmitter) will listen to all transmissions to stay synchronized, but will not send any of the data out their serial ports. E0 (Echo Off) Command Command Summary AT Command: ATE0 Binary Command: 0x0A (10 decimal) Description

<Command Mode Options> E0 Command turns off character echo in AT Command Mode. By default, echo is off. 2011DigiInternational,Inc. 23 XBeePROXSCOEMRFModules E1 (Echo On) Command Command Summary AT Command: ATE1 Binary Command: 0x0B (11 decimal) Description

<Command Mode Options> E1 Command turns on the echo in AT Command Mode. Each typed character will be echoed back to the terminal when ATE1 is active. E0 is the default. ER (Receive Error Count) Command Command Summary AT Command: ATER Binary Command: 0x0F (15 decimal) Parameter Range:0 0xFFFF Default Parameter Value: 0 Number of bytes returned: 2 Related Commands: GD (Receive Good Count) Description

<Diagnostics> Set/Read the receive-

error. The error-count records the number of packets partially received then aborted on a reception error. This value returns to 0 after a reset and is not non-volatile (Value does not persist in the modules memory after a power-up sequence). 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 the module is reset. FH (Force Wake-up Initializer) Command Command Summary AT Command: ATFH Binary Command: 0x0D (13 decimal) Description

<Sleep (Low Power)> FH Command is used to force a Wake-up Initializer to be sent on the next transmit. WR (Write) Command does not need to be issued with FH Command. Use only with cyclic sleep modes active on remote modules. FL (Software Flow Control) Command Command Summary AT Command:

ATFL Binary Command: 0x07 (7 decimal) Parameter Range: 0 1 Parameter Value Configuration flow control flow control Default Parameter Value: 0 Number of bytes returned: 1 Disable software Enable software 0 1 Description

<Serial Interfacing> FL Command is used to configure software flow control. Hardware flow control is implemented with the Module as the DO2 pin (), which regulates when serial data can be transferred to the module. FL Command can be used to allow software flow control to also be enabled. XON character used is 0x11 (17 decimal). XOFF character used is 0x13 (19 decimal). 2011DigiInternational,Inc. 24 XBeePROXSCOEMRFModules FR (Force Reset) Command Command Summary AT Command: ATFR Binary Command: Not available Description

<Special> FR command is used in order to reset the module through the UART. The characters OK<CR> will be returned and the module will reset 100ms FT (Flow Control Threshold) Command Command Summary AT Command: ATFT Binary Command: 0x24 (36 decimal) Parameter Range:0 (DI buffer size minus 0x11 bytes) Default Parameter Value: DI Buffer size minus 0x11 (17 decimal) Number of bytes returned: 2 Minimum Firmware Version Required:

4.27B Description

<Serial Interfacing> Flow Control Threshold - Set or read flow control threshold. De-assert CTS and/or send XOFF when FT bytes are in the UART receive buffer. Re-assert CTS when less than FT - 16 bytes are in the UART receive buffer. GD (Receive Good Count) Command Command Summary AT Command: ATGD Binary Command: 0x10 (16 decimal) Parameter Range:0 0xFFFF Default Parameter Value: 0 Number of bytes returned: 2 Related Commands: ER (Receive Error Count) Description

<Diagnostics> Set/Read the count of good received RF packets. Parameter value is reset to 0 after every reset and is not non-volatile (Value does not persist in the modules memory after a power-up sequence). Once the Receive Good Count reaches its maximum value (up to 0xFFFF), it remains at its maximum count value until the maximum count value is manually changed or the module is reset. HP (Hopping Channel) Command Command Summary AT Command: ATHP Binary Command: 0x11 (17 decimal) Parameter Range:0 6 Default Parameter Value: 0 Number of bytes returned: 1 Related Commands: DT (Destination Address), ID (Module VID), MK (Address Mask) Description

<Networking> HP Command is used to set the modules hopping channel number. A channel is one of three layers of addressing available to the module. In order for modules to communicate with each other, the modules must have the same channel number since each network uses a different hopping sequence. Different channels can be used to prevent modules in one network from listening to transmissions of another. 2011DigiInternational,Inc. 25 XBeePROXSCOEMRFModules HT (Time before Wake-up Initializer) Command Command Summary AT Command: ATHT Binary Command: 0x03 (3 decimal) Parameter Range:0 0xFFFF

[x 100 milliseconds]

Default Parameter Value: 0xFFFF (means that long wake-up initializer will not be sent) Number of bytes returned: 2 Related Commands: LH (Wake-up Initializer Timer), SM (Sleep Mode), ST

(Time before Sleep) Description

<Sleep (Low Power)> If any modules within range are running in a Cyclic Sleep setting, a wake-up initializer must be used by the transmitting module for sleeping modules to remain awake [refer to the LH (Wake-up InitializerTimer) Command]. When a receiving module in Cyclic Sleep wakes, it must detect the wake-up initializer in order to remain awake and receive data. The value of HT Parameter tells the transmitter, After a period of inactivity (no transmitting or receiving) lasting HT amount of time, send a long wake-up initializer. HT Parameter should be set to match the inactivity time out

[specified by ST (Time before Sleep) Command]

used by the receiver(s). From the receiving module perspective, after HT time elapses and the inactivity time out [ST Command] is met, the receiver goes into cyclic sleep. In cyclic sleep, the receiver wakes once per sleep interval to check for a wakeup initializer. When a wake-up initializer is detected, the module will stay awake to receive data. The wake-up initializer must be longer than the cyclic sleep interval to ensure that sleeping modules detect incoming data. When HT time elapses, the transmitter then knows that it needs to send a long Wake-up Initializer for all receivers to be able to remain awake and receive the next transmission. Matching HT to the time specified by ST on the receiving module guarantees that all receivers will detect the next transmission. ID (Modem VID) Command Command Summary AT Command: ATID Binary Command: 0x27 (39 decimal) Parameter Range (user-set table) 0x10 -

0x7FFFF

(Factory-set and read-only) 0x8000 0xFFFF Number of bytes returned: 2 Description

<Networking> Set/Read the Vendor Identification Number. Only modems with matching IDs can communicate with each other. Modules with non-

matching VIDs will not receive unintended data transmission. 2011DigiInternational,Inc. 26 XBeePROXSCOEMRFModules LH (Wake-up Initializer Timer) Command Command Summary AT Command: ATLH Binary Command: 0x0C (12 decimal) Parameter Range:0 0xFF

[x 100 milliseconds]

Default Parameter Value: 1 Number of bytes returned: 1 Related Commands: HT (Time before Wake-up Initializer), SM (Sleep Mode), ST

(Time before Sleep) Description

<Sleep (Low Power)> LH Command adjusts the duration of time for which the RF initializer is sent. When receiving modules are put into Cyclic Sleep Mode, they power-down after a period of inactivity [specified by ST (Time before Sleep) Command] and will periodically awaken and listen for transmitted data. In order for the receiving modules to remain awake, they must detect~35ms of the wake-up initializer. LH Command must be used whenever a receiver is operating in Cyclic Sleep Mode. This lengthens the Wake-up Initializer to a specific amount of time (in tenths of a second). The Wake-up Initializer Time must be longer than the cyclic sleep time that is determined by SM (Sleep Mode) Command. If the wake-up initializer time were less than the Cyclic Sleep interval, the connection would be at risk of missing the wake-up initializer transmission. Refer to Figures 3.1 & 3.2 of the SM Command description to view diagrams of correct and incorrect configurations. The images help visualize the importance that the value of LH be greater than the value of SM. MD (RF Mode) Command Command Summary AT Command: ATMD Binary Command: 0x32 (50 decimal) Parameter Range: 0 4 Parameter 0 1 2 3 4 Configuration Peer-to-Peer

(transparent operation) Multi-Steam Base Multi-Steam Remote Repeater & End Node End Node Default Parameter Value: 0 Number of bytes returned: 1 Related Commands: CB (Connection Duration Time out), CE (Connection Inactivity Time out), CM (Connection Message), DC (Disconnect) This command is only supported on S3B modules. Description

<Networking & Security> The MD command is used to select/read the RF Mode (Peer-to-peer, Multi-Stream or Repeater Modes) of the module. Multi-Streaming Mode enables exclusive connections in point-to-multipoint networks. Refer to the Multi-Streaming Mode section [p43] for more information regarding how these parameter values affect other parameter values. Repeater Mode enables longer range via an intermediary module. When MD=3, the module will act as a store and forward repeater. Any packets not addressed to this node will be repeated. A Repeater End Node (MD=4) handles repeated messages, but will not forward the data over-the-air. Refer to the Repeater Mode section [p38] for more information. 2011DigiInternational,Inc. 27 XBeePROXSCOEMRFModules MK (Address Mask) Command Command Summary AT Command: ATMK Binary Command: 0x12 (18 decimal) Parameter Range:0 0xFFFF Default Parameter Value: 0xFFFF

(Destination address (DT parameter) of the transmitting module must exactly match the destination address of the receiving module.) Number of bytes returned: 2 Related Commands: DT (Destination Address), HP (Hopping Channel), ID

(Module VID) Description

<Networking> MK Command is used to set/read the Address Mask. All data packets contain the Destination Address of the transmitting module. When an RF data packet is received, the transmitters Destination Address is logically ANDed (bitwise) with the Address Mask of the receiver. The resulting value must match the Destination Address or the Address Mask of the receiver for the packet to be received and sent out the modules DO serial port. If the ANDed value does not match either the Destination Address or the Address Mask of the receiver, the packet is discarded. (All 0 values are treated as irrelevant values and are ignored.) MY (Source Address) Command Description

<Networking & Security> Set/Read the source address of the module. Refer to the Addressing section [p36] of the RF Communication Modes chapter for more information. Command Summary AT Command: ATMY Binary Command: 0x2A (42 decimal) Parameter Range: 0 0xFFFF Default Parameter Value: 0xFFFF

<Command Mode Options> PC Command allows the module to power-up directly into AT Command Mode from reset or power-on. If PC Command is enabled with SM Parameter set to 1, DI3

(pin 9) can be used to enter the module into AT Command Mode. When the DI3 pin is de-

asserted (low), the module will wake-

up in AT Command Mode. This behavior allows module DTR emulation. PK (RF Packet Size) Command Command Summary AT Command: ATPK Binary Command: 0x29 (41 decimal) Parameter Range: 0 0x100 [Bytes]

Default Parameter Value: 0x40 (64 decimal) Number of bytes returned: 2 Related Commands: RB (Packetization Threshold), RO (Packetization Time out) This command is only supported on S3B modules. Description

<Serial Interfacing> Set/Read the maximum size of the RF packets sent out a transmitting module. The maximum packet size can be used along with the RB and RO parameters to implicitly set the channel dwell time. Changes to this parameter may have a secondary effect on the RB (Packet Control Characters) parameter. RB must always be less than or equal to PK. If PK is changed to a value less than the current value of RB, RB is automatically lowered to be equal to PK. PL (Module Power Level) Command Description

<Special Commands> Set/Read the power level at which the RF module transmits conducted power. This command is only supported on S3B hardware. Power level 4 is calibrated and the other power levels are approximate. Command Summary AT Command: ATPL Binary Command: 0x3C (60 decimal) Parameter Range:0 4 Parameter Value 0 1 2 3 4 Configuration

(Time before Sleep) Description

<Sleep (Low Power)> Under normal operation, a module in Cyclic Sleep Mode cycles from an active state to a low-power state at regular intervals until data is ready to be received. If the PW Parameter is set to 1, SLEEP (pin 2) can be used to wake the module from Cyclic Sleep. If the SLEEP pin is de-asserted (low), the module will be fully operational and will not go into Cyclic Sleep. Once SLEEP is asserted, the module will remain active for the period of time specified by ST

<Serial Interfacing> RF transmission will commence when data is in the DI Buffer and either of the following criteria are met:

RO times out on the UART receive lines

(ignored if RO = 0) RB characters have been received by the UART (ignored if RB = 0) If PK is lowered below the value of RB; RB is automatically lowered to match PK. Note: RB and RO criteria only apply to the first packet of a multi-packet transmission. If data remains in the DI Buffer after the first packet, transmissions will continue in streaming manner until there is no data left in the DI Buffer (UART receive buffer). RE (Restore Defaults) Command Command Summary AT Command: ATRE Binary Command: 0x0E (14 decimal) Description

<Diagnostics> RE Command restores all configurable parameters to factory default settings. However, RE Command will not write the default values to non-volatile (persistent) memory. Unless the WR (Write) Command is issued after the RE command, the default settings will not be saved in the event of module reset or power-down. 2011DigiInternational,Inc. 30 XBeePROXSCOEMRFModules RN (Delay Slots) Command Command Summary AT Command: ATRN Binary Command: 0x19 (25 decimal) Parameter Range:0 0xFF [slots]

Default Parameter Value: 0 (no delay slots inserted) Number of bytes returned: 1 Description

<Networking> RN Command is only applicable if retries have been enabled [RR (Retries) Command], or if forced delays will be inserted into a transmission [refer to TT (Streaming Limit) Command]. RN Command is used to adjust the time delay that the transmitter inserts before attempting to resend a packet. If the transmitter fails to receive an acknowledgement after sending a packet, it will insert a random number of delay slots

(ranging from 0 to (RN minus 1)) before attempting to resend the packet. Each delay slot lasts for a period of 38ms. If two modules attempted to transmit at the same time, the random time delay after packet failure would allow one of the two modules to transmit the packet successfully, while the other would wait until the channel opens up to begin transmission. RO (Packetization Time out) Command Command Summary AT Command: ATRO Binary Command: 0x21 (33 decimal) Parameter Range:0 0xFFFF [x 200 s]

Default Parameter Value: 0 Number of bytes returned: 2 Description

<Serial Interfacing> RO Command is used to specify/read the time of silence (no bytes received) after which transmission begins. After a serial byte is received and if no other byte is received before the RO time out, the transmission will start. RP (RSSI PWM Timer) Command Command Summary AT Command: ATRP Binary Command: 0x22 (34 decimal) Parameter Range:0 - 0x7F

[x 100 milliseconds]

Default Parameter Value: 0 (disabled) Number of bytes returned: 1 Description

<Diagnostics> RP Command is used to enable a PWM (Pulse Width Modulation) output on the Config pin which is calibrated to show the level the received RF signal is above the sensitivity level of the module. The PWM pulses vary from zero to 95 percent. Zero percent means the received RF signal is at or below the published sensitivity level of the module. The following table shows levels above sensitivity and PWM values. The total period of the PWM output is 8.32 ms. There are 40 steps in the PWM output and therefore the minimum step size is 0.208 ms. 2011DigiInternational,Inc. 31 XBeePROXSCOEMRFModules Table303. PWMChart dBm above Sensitivity 10 20 30 PWM percentage

(high period / total period) 47.5 %

62.5 %

77.5 %

A non-zero value defines the time that the PWM output will be active with the RSSI value of the last received RF packet. After the set time when no RF packets are received, the PWM output will be set low (0 percent PWM) until another RF packet is received. The PWM output will also be set low at power-up. A parameter value of 0xFF permanently enables the PWM output and it will always reflect the value of the last received RF packet. PWM output shares the Config input pin. When the module is powered, the Config pin will be an input. During the power-up sequence, the Config pin will be read to determine whether the module is going into AT Command Mode. After this, if RP parameter is a non-zero value, the Config pin will be configured as an output and set low until the first RF packet is received. With a non-zero RP parameter, the Config pin will be an input for RP ms after power up. RZ (DI Buffer Size) Command Command Summary AT Command: ATRZ Binary Command: 0x2C (44 decimal) Parameter Range:Read-only Number of bytes returned: 1 This command is only supported on S3B modules. Description

<Diagnostics> The RZ command is used to read the size of the DI buffer (UART RX

(Receive)). Note: The DO buffer size can be determined by multiplying the DI buffer size by 1.5. RR (Retries) Command Command Summary AT Command: ATRR Binary Command: 0x18 (24 decimal) Parameter Range:0 0xFF Default Parameter Value: 0 (disabled) Number of bytes returned: 1 Description Networking> RR Command specifies the number of retries that can be sent for a given RF packet. Once RR Command is enabled (set to a non-zero value), RF packet acknowledgements and retries are enabled. After transmitting a packet, the transmitter will wait to receive an acknowledgement from a receiver. If the acknowledgement is not received in the period of time specified by the RN (Delay Slots) Command, the transmitter will transmit the original packet again. The packet will be transmitted repeatedly until an acknowledgement is received or until the packet has been sent RR times. Note: For retries to work correctly, all modules in the system must have retries enabled. 2011DigiInternational,Inc. 32 XBeePROXSCOEMRFModules RS (RSSI) Command Command Summary AT Command: ATRS Binary Command: 0x1C (28 decimal) Parameter Range: 0x06 0x36 [read-

Number of bytes returned: 2 Related Commands: SH (Serial Number High) Description

<Diagnostics> Read the serial number low word of the module. SM (Sleep Mode) Command Description

<Sleep Mode (Low Power)> SM Command is used to adjust Sleep Mode settings. By default, Sleep Mode is disabled and the module remains continually active. SM Command allows the module to run in a lower-powerstate and be configured in one of eight settings. Cyclic Sleep settings wake the module after the amount of time designated by SM Command. If the module detects a wake-up initializer during the time it is awake, it will synchronize with the transmitter and start receiving data after the wake-up initializer runs its duration. Otherwise, it returns to Sleep Mode and continue to cycle in and out of inactivity until the Wake-up Initializer is detected. If a Cyclic Sleep setting is chosen, the ST, LH and HT parameters must also be set as described in the Sleep Mode section of this manual.

Default Parameter Value: 0x64 (100 decimal) Number of bytes returned: 2 Related Commands: SM (Sleep Mode), LH

(Wake-up Initializer Timer), HT (Time before Wake-up Initializer) Description

<Sleep Mode (Low Power)> ST Command sets the period of time (in tenths of seconds) in which the module remains inactive before entering into Sleep Mode. For example, if the ST Parameter is set to 0x64 (100 decimal), the module will enter into Sleep mode after 10 seconds of inactivity

(no transmitting or receiving). This command can only be used if Cyclic Sleep or Serial Port Sleep Mode settings have been selected using SM (Sleep Mode) Command. 2011DigiInternational,Inc. 34 XBeePROXSCOEMRFModules SY (Time before Initialization) Command Command Summary AT Command: ATSY Binary Command: 0x17 (23 decimal) Parameter Range:0 0xFF

Default Parameter Value: 0 (Disabled -

channel initialization information is sent with each RF packet.) Number of bytes returned: 1 Description

<Networking> SY Command keeps a communication channel open as long as module transmits or receives before the active connection expires. It can be used to reduce latency in a query/

response sequence and should be set 100 ms longer than the delay between transmissions. This command allows multiple Modules to share a hopping channel for a given amount of time after receiving data. By default, all packets include an RF initializer that contains channel information used to synchronize any listening receivers to the transmitters hopping pattern. Once a new module comes within range, it is able to instantly synchronize to the transmitter and start receiving data. If no new modules are introduced into the system, the synchronization information becomes redundant once modules have become synchronized. SY Command allows the modules to remove this information from the RF Initializer after the initial synchronization. For example, changing the SY Parameter to 0x14 (20 decimal) allows all modules to remain in sync for 2 seconds after the last data packet was received. Synchronization information is not re-sent unless transmission stops for more than 2 seconds. This command allows significant savings in packet transmission time. Warning: Not recommended for use in an interference-prone environment. Interference can break up the session and the communications channel will not be available again until SY time expires. With SY set to zero, the channel session is opened and closed with each transmission - resulting in a more robust link with more latency. TR (Transmit Error Count) Command Command Summary AT Command: ATTR Binary Command: 0x1B (27 decimal) Parameter Range:0 0xFFFF Default Parameter Value: 0 Number of bytes returned: 2 Related Commands: RR (Retries) Description

<Diagnostics> TR Command records the number of retransmit failures. This number is incremented each time a packet is not acknowledged within the number of retransmits specified by the RR (Retries) Command. It therefore counts the number of packets that were not successfully received and have been dropped. The TR Parameter is not non-volatile and will therefore be reset to zero each time the module is reset. 2011DigiInternational,Inc. 35 XBeePROXSCOEMRFModules TT (Streaming Limit) Command Command Summary AT Command: ATTT Binary Command: 0x1A (26 decimal) Parameter Range:0 0xFFFF (0 =

disabled) Default Parameter Value: 0xFFFF (65535 decimal) Number of bytes returned: 2 Related Commands: RN (Delay Slots) Description

<Networking> TT Command defines a limit on the number of bytes that can be sent out before a random delay is issued. TT Command is used to simulate full-duplex behavior. If a module is sending a continuous stream of RF data, a delay is inserted which stops its transmission and allows other modules time to transmit

(once it sends number of bytes specified by TT Command). Inserted random delay lasts between 1 & RN + 1 delay slots, where each delay slot lasts 38 ms. 2011DigiInternational,Inc. 36 XBeePROXSCOEMRFModules AppendixA:AgencyCertifications FCC (United States) Certification The XBee-PRO XSC OEM RF Module complies with Part 15 of the FCC rules and regulations.
