The data flow sequence is initiated when the first byte of data is received in the DI Buffer of the
transmitting module (XBee Module A). As long as XBee Module A is not already receiving RF data,
data in the DI Buffer is packetized, then transmitted over-the-air to XBee Module B.

2. RF Module Operation
2.1. 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. UART-Interfaced Data Flow
Devices that have a UART interface can connect directly through the pins of the XBee module as shown in the
figure below.

(Low‐asserted signals distinguished with horizontal line over signal name.)
DIN (data in)
DIN (data in)
DOUT (data out)
DOUT (data out)
2.1.2. 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.

2.1.3. Flow Control
Figure 2‐03. Internal Data Flow Diagram (The five most commonly‐used pin signals shown.)
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 hardware 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.

XBee‐PRO® XSC OEM RF Modules
2.2. Modes of Operation
XBee-PRO® XSC RF Modules operate in five modes.
Figure 2‐04. Modes of Operation
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.

XBee‐PRO® XSC OEM RF Modules
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 initializer used to wake remote modems from Sleep Mode (Refer to the FH, LH, HT and SM Commands for more information). The length of the wake-up initializer should be longer than the
length of time remote modems are in cyclic sleep.
© 2011 Digi International, Inc.
12
XBee‐PRO® XSC OEM RF Modules
Header
The header contains network addressing information that filters incoming RF data. The receiving modem checks for a matching Hopping Channel (HP parameter), Vendor Identification Number (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.
Figure 2‐05. Reception of RF Data
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.

(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.
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 userdefined 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”

XBee‐PRO® XSC OEM RF Modules
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 wakeup initializer portion of data transmission in order to be synchronized with the transmitting module
and receive the data.
Figure 2‐06. Correct Configuration (LH > SM)
Length of the wake‐up initializer exceeds the time interval of Cyclic Sleep. The receiver is guaranteed to detect
the wake‐up initializer and receive the accompanying payload data.
Figure 2‐07. 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).
2.2.4. 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 available for programming the module:
• AT Commands
• Binary Commands
For modified parameter values to persist in the module registry, changes must be saved to non-volatile memory using WR (Write) Command. Otherwise, parameters are restored to previously saved values 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 ‘Terminal’ 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 DataIn 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]).

XBee‐PRO® XSC OEM RF Modules
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.
Figure 2‐8. Syntax for sending AT Commands
To read a parameter value stored in the module register, leave the parameter field blank.
The preceding example would change the module’s 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 Timeout) 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 configurable 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].

16
XBee‐PRO® XSC OEM RF Modules
A minimum time delay of 100 µs (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 (bitwise) 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.
Figure 2‐09. Binary Command Write then Read
Signal #4 is CMD (pin 16)
Signal #1 is the DIN (pin 3) signal
to the radio
Signal #2 is the DOUT (pin 2) signal
from the radio
Signal #3 is CTS (pin 12)
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) parameter must be set to one. If binary programming is not enabled RT = 0 or 2, the module will not recognize that the CMD pin is asserted and therefore will not recognize the data as binary commands.

3.1. XBee Programming Examples
For information about entering and exiting AT and Binary Command Modes, refer to the Command
Mode section.
3.1.1. AT Commands
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 (Destination Address) parameter and save the new address to non-volatile memory. This example
requires the installation of Digi’s X-CTU Software and a serial connection to a PC.
Note: Do not send com‐
mands to the module
during flash program‐
ming (when parameters
are being written to the
module registry).
Wait for the “OK” sys‐
tem response that fol‐
lows the ATWR
command before enter‐
ing the next command
or use flow control.
Select the ‘Terminal’ tab of the X-CTU Software and enter the following command lines:
Method 1 (One line per command)
Send AT Command
+++
ATDT
ATDT1A0D
ATWR
ATCN
System Response
OK (Enter into Command Mode)
{current value} (Read Destination Address)
OK (Modify Destination Address)
OK (Write to non-volatile memory)
OK (Exit Command Mode)
Method 2 (Multiple commands on one line)
Send AT Command
+++
ATDT
ATDT1A0D,WR,CN
System Response
OK (Enter into Command Mode)
{current value} (Read Destination Address)
OK (Execute commands)
Note: When using X-CTU Software to program a module, PC com port settings must match the baud
(interface data rate), parity & stop bits parameter settings of the module. Use the 'Com Port Setup'
section of the “PC Settings” tab to configure PC com port settings to match those of the module.
3.1.2. Binary Commands
To Send Binary Commands
Example: Use binary commands to change the XBee module's destination address to 0x1A0D
and save the new address to non-volatile memory.
1.
RT Command must be set to "1" in AT Command Mode to enable binary programming.
2.

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
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

Default Parameter Value: Set to equal
module’s factory-set RF data rate.
Table 3‐02.
Description
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. Nonstandard 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.

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.

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
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.

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
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.

Description
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

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
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 µs]
Default Parameter Value: 0
Number of bytes returned: 2
Description
RO Command is used
to specify/read the time of

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

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.

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.

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

SY (Time before Initialization) Command
Command Summary
AT Command: ATSY
Binary Command: 0x17 (23 decimal)
Parameter Range:0 – 0xFF
[x 100 milliseconds]
Default Parameter Value: 0 (Disabled channel initialization information is sent
with each RF packet.)
Number of bytes returned: 1
Description
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
transmitter’s 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.

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.

Fixed Base Station and Mobile Applications
Digi RF Modules are pre-FCC approved for use in fixed base station and mobile applications. When
the antenna is mounted at least 20cm (8") from nearby persons, the application is considered a
mobile application.
Portable Applications and SAR Testing
When the antenna is mounted closer than 20cm to nearby persons, then the application is
considered “portable” and requires an additional test be performed on the final product. This test
is called Specific Absorption Rate (SAR) testing and measures the emissions from the module and
how they affect the person.
RF Exposure
This statement must be included as a CAUTION statement in OEM product manuals.
WARNING: This equipment is approved only for mobile and base station transmitting
devices. Antenna(s) used for this transmitter must be installed to provide a separation
distance of at least 20 cm from all persons and must not be co-located or operating in
conjunction with any other antenna or transmitter.
IC (Industry Canada) Certification
Labeling requirements for Industry Canada are similar to those of the FCC. A clearly visible label
on the outside of the final product enclosure must display one of the following text:
For XBEE PRO S3 Contains Model: XBEEXSC, IC: 1846A-XBEEXSC
OR
For XBEEPRO S3B Contains Model: XBPS3B, IC: 1846A-XBPS3B
Integrator is responsible for its product to comply with IC ICES-003 & FCC Part 15, Sub. B Unintentional Radiators. ICES-003 is the same as FCC Part 15 Sub. B and Industry Canada accepts
FCC test report or CISPR 22 test report for compliance with ICES-003.

XBee‐PRO® XSC OEM RF Modules
Transmitter Antennas
This device has been designed to operate with the antennas listed below, and having a maximum
gain of 15.1 dB. Antennas not included in this list or having a gain greater than 15.1 dB are strictly
prohibited for use with this device. The required antenna impedance is 50 ohms.
Operation is subject to the following two conditions: (1) this device may not cause interference,
and (2) this device must accept any interference, including interference that may cause undesired
operation of the device.
To reduce potential radio interference to other users, the antenna type and its gain should be so
chosen that the equivalent isotopically radiated power (e.i.r.p.) is not more than that permitted for
successful communication
