This section includes information that applies to all XBee™ Adapter,
Router, and Sensor products.
About this guide
This guide describes the features and functions of XBee Adapter, Router,
and Sensor products, including connection and setup information, pinouts,
configuration, data retrieval, and LEDs and buttons.
This section provides general information that applies to all products.
Scope
This guide covers all XBee ZNet 2.5 (Series 2) adapter, router, and sensor
products.
Compatibility Note
Two sets of XBee and XBee-PRO adapters are offered: Series 1 and
Series 2. Though overall performance and product specifications are
largely similar, the two series are built on distinct and non-compatible
technology platforms. Thus, users must standardize on one series or the
other for operability. The same is true for compatibility with the
ConnectPort X gateways. Series 1 XBee adapters are compatible only with
Series 1 gateways, while Series 2 XBee adapters are compatible only with
Series 2 gateways.
Mounting orientation
All XBee Adapters can be mounted in any orientation.
Warranty exception for batteries
Some XBee Adapters and Sensor products ship with alkaline batteries that
must be replaced by the user when discharged and are not covered under
the terms and conditions of the Digi warranty.
Lithium batteries must be replaced by qualified service personnel.

XBee RS-232 Adapter
XBee RS-232 Adapter
Chapter 2
Overview
The XBee RS-232 Adapter provides short range wireless connectivity to
any RS-232 serial device, with available solutions for both mesh (including
ZigBee) and point-to-multipoint networks. Unlike an embedded wireless
module, which requires design integration and development time, these
off-the-shelf adapters provides instant wireless connectivity to existing
RS-232 serial devices. All XBee adapters can be used with Digi's
ConnectPort X gateways for data aggregation and IP connectivity.
Power options
Depending on adapter model, there are several powering options.
Alkaline battery model
This product can be powered by a 9-30VDC external power supply (see
"Power requirements" on page 67) or by batteries. Use 3x1.5V “N” alkaline
battery cells. To install batteries, insert a screwdriver in the slots in the side
of the adapter case and twist to snap off the cover. Insert the batteries
following the polarity diagram on the board.
Lithium battery model
This model can be powered by a 3-6VDC external power supply or by 2/3
AA 3.6V lithium batteries and a 1/2 AA boost capacitor. Replacement
batteries available for purchase; contact Digi at 952-912-3444 or
877-912-3444.
Connection and power-on
1. Connect the desired device to the RS-232 port of the adapter.

XBee RS-232 PH Adapter
XBee RS-232 PH Adapter
Overview
The XBee RS-232 PH Adapter provides short range wireless connectivity
to any RS-232 serial device, with available solutions for both mesh
(including ZigBee) and point-to-multipoint networks. Unlike an embedded
wireless module, which requires design integration and development time,
these off-the-shelf adapters provides instant wireless connectivity to
existing RS-232 serial devices. All XBee adapters can be used with Digi's
ConnectPort X gateways for data aggregation and IP connectivity
Using a powering mode known as power harvesting (PH), this adapter is
powered by the connected host device through its RS-232 serial port.
Power requirements
This product requires a fully functional serial port conforming to the
RS-232C standard for optimal operation. It requires a sleep/wake duty
cycle as part of its normal operation. An internal battery provides power
when the adapter is operating, and recharges from the serial port when in
sleep mode. The sleep/wake duty cycle requirements vary based on the
current output of serial port
Serial ports that provide hard power of 5 to 14VDC on one or more pins
allow the device to operate continually without a sleep/wake cycle.
WARNING: Do not use this adapter with serial ports with more than 14VDC
output as they may cause the adapter to malfunction.
Connection and power-on
Connect the adapter to the RS-232 port of the host device.
The adapter’s power comes from the host’s serial port.

XBee RS-232 PH Adapter
Configuration
There are four key attributes of the Serial PH adapter’s firmware that allow
it to have a net charge on its batteries:
• Sleep Mode (SM)
• Idle Time (ST)
• Sleep Period (SP)
• Sleep Number (SN)
Sleep mode, determines what sleeping behavior the adapter has. By
default the adapter has cyclical sleep enabled. With cyclical sleep enabled,
if the adapter is idle (No RS-232 traffic, no transmit/receive) for the given
amount of Idle Time, it then performs Sleep Number amount of sleeping
cycles, each for the duration of the value of Sleep Period.
The default sleep mode settings are:
• SM = 4 (Cyclical sleep enabled)
• ST = 0x3E8 (Idle time of 1 second)
• SP = 0x40 (Each sleep period’s duration is 640 ms)
• SN = 1 (Perform 1 sleep period when sleeping)
For this configuration, the adapter would sleep for a total of 640 ms when
performing a sleep period, after it was idle for 1 second. During an RF
receive/transmit, the device is in an active state for a significant amount of
time, regardless of the Idle Time setting. If continuous requests/queries are
made to the device, it will stay in an active state, which can lead to a net
discharge of the battery, and eventually the adapter will become
unresponsive.
Adjusting the default settings is not recommended. Doing so can lead to
unit that will not power on. The fix is to remove the module from the adapter
and plug it into the serial line. Then, you can adjust these parameters
through X-CTU software. This software is available on the Software and
Documentation CD that accompanies Drop-in Networking kits and
ConnectPort X gateways.
The battery can take up to 24 hours to fully charge, and if the unit is run in
the worst-case scenario, no sleep mode enabled and continuously queried,
the battery has only a charge for around 40 minutes. After that, the unit will
become unresponsive. In addition, if the unit isn’t immediately put into a
sleep mode after the battery first becomes unable to power the adapter, the
battery will further deplete, and you will have to perform the fix mentioned
above to recover the device.
Data retrieval
Retrieving data from XBee adapters is done by issuing a remote AT IS
(Force Sample) command through the XBee API. The XBee API and AT IS
command are described in detail in the XBee ZNet 2.5 (Series 2) RF
Module data sheet. AT IS commands can be issued via a Python program
that is executed on the gateway. See also the Product Manual for the XBee
Module and the Digi Python Programming Guide.

Chapter 5
XBee Analog I/O Adapter
Overview
The XBee Analog I/O Adapter provides short range wireless connectivity to
any analog device, with available solutions for both mesh (including
ZigBee) and point-to-multipoint networks. Unlike an embedded wireless
module, which requires design integration and development time, these
off-the-shelf adapters provides instant wireless connectivity to existing
analog devices. All XBee adapters can be used with Digi's ConnectPort X
gateways for data aggregation and IP connectivity.
The XBee Analog I/O adapter allows for several potential interfaces to
analog devices. It provides greater flexibility and uses than the Digi XBee
Sensor Adapter and XBee Sensor products, in that:
• It can be used with a variety of off-the-shelf sensor products.
• It can be used in situations when the item being measured or analyzed
needs to be separated from the sensor/measuring device itself.
Analog Modes
The XBee Analog I/O Adapter has three modes in which it can measure
input on its four terminal lines.
• 0-10 volt mode: The device measures the voltage on a scale of 1 to 10
volts, and translates it into a 10-bit scale from 0 to 1023 as possible
values.
• Current Loop (4 mA to 20 mA) mode: The device measures the
amperage on a scale of 4 mA to 20 mA, and translates it into a 10-bit
scale from 0 to 1023 as possible values.
• Differential input mode: The device measures paired terminals (1 and
2 paired, 3 and 4 paired) and translates the difference in voltage
between the two lines to into a 10-bit scale from 0 to 1023 as possible
values.
A Python module named xbeeain.py is available to set the analog mode;
see pages 24 and 25.

Enable a terminal line for measurement
To enable a terminal line for measurement, the following analog I/O lines
have to be set to value 2:
• D0
• D1
• D2
• D3
D0, D1, D2, and D3 represent terminal lines 1, 2, 3, and 4 respectively. In
the case of a terminal pair in differential mode, only the first terminal of the
terminal pair should be enabled. To disable a terminal line, set the
respective analog I/O line to value 0.

Power output specifications
External terminal 6 is a power-out pin. It can be set to either battery pack
voltage out or +12VDC at 50mA out via DIP switches 1 and 2.
External terminal 5 is a system ground pin. This ground pin should be used
for all external ground connections for both power and input connections.
DIP switch 1 enables battery pack voltage minus .5VDC to terminal 6,
resulting in 4VDC out with new alkaline batteries, or 3.1VDC with new
lithium battery. DIP switch 2 enables +12VDC to terminal 6. Only one
switch should be on at a time. No damage will happen if both are set to on,
but the output will default to the +12VDC output and increased parasitic
battery drain will result.
The battery pack voltage is on terminal 6 all the time, and is not gated with
the sleep of the module when DIP switch 2 is on. Any current draw from
terminal 6 will result in reduced battery life.
When DIP switch 2 is on, the +12VDC at 50mA max is provided at terminal
6. This power is gated by both the sleep of the module and AT command
P3. For this power setting to be on, the XBee module needs to be awake
and AT command P3 set to a high level.

XBee Digital I/O Adapter
Chapter 6
Overview
The XBee Digital I/O Adapter provides short range wireless connectivity to
any digital device, as well as an interface to logic-level inputs and sinking
driver output. Solutions are available for both mesh (including ZigBee) and
point-to-multipoint networks. Unlike an embedded wireless module, which
requires design integration and development time, these off-the-shelf
adapters provides instant wireless connectivity to existing digital devices.
All XBee adapters can be used with Digi's ConnectPort X gateways for
data aggregation and IP connectivity.
Power options
Depending on adapter model, there are several powering options.
Alkaline battery model
This product can be powered by a 9-30VDC external power supply (see
"Power requirements" on page 67) or by batteries. Use 3x1.5V “N” alkaline
battery cells. To install batteries, insert a screwdriver in the slots in the side
of the adapter case and twist to snap off the cover. Insert the batteries
following the polarity diagram on the board.
Lithium battery model
This model can be powered by a 3-6VDC external power supply or by 2/3
AA 3.6V lithium batteries and a 1/2 AA boost capacitor. Replacement
batteries available for purchase; contact Digi at 952-912-3444 or
877-912-3444.

XBee Digital I/O Adapter
Connection and power-on
1. Connect the wires for the desired digital device to the connector for the
adapter. The connector for the adapter is a 6-position wire terminal
block. The connector accommodates wire gauges from 16AWG to
30AWG. The figure shows Pin 1 of the connector when the adapter is
oriented with the mounting tabs, facing upwards (the underside of the
adapter).
To insert or remove wires, insert a screwdriver blade in the slot directly
below the hole where the wire inserts. Press down on the spring to
open up the hole and insert or remove the wire.
2. Connect the power supply to the adapter or insert batteries.
Pinouts
Facing the connector, with the screwdriver release slots down, going from
right to left, the pinouts are:

Note:
• Switches 1 and 2 should not be on at the same time as increased
parasitic battery drain will result.
• Pullup use is not recommended when running from battery power,
owing to the constant drain on the batteries.
32
XBee Digital I/O Adapter
Configuring inputs and outputs
As shown in the pinouts table, the XBee Digital I/O Adapter product has
four external terminals that can be set as either a digital input or a sinking
driver output.
The XBee module controls the sinking drivers on pins 11, 16, 12, 4 for
terminals 1, 2, 3, 4 respectively.
The AT commands to the XBee module for the output function are D4, D6,
D7, P2 for terminals 1, 2, 3, 4 respectively.
Outputs are activated (that is, the sinking function is turned on) by setting
high the corresponding XBee pin for the output that is desired. To set a
terminal high, set the corresponding AT command to value 5. To set a
terminal low, set the corresponding AT command to value 4. For example,
setting terminal 1 to high would call the AT command D4 and set it to value
5.
Since the input and output functions overlap, the input function is always
active and when the input function is desired, the output control pin for the
matching output must be set low (turns off the sinking function). This
feature can allow the inputs to monitor the output sinking operation if
desired.

The battery pack voltage is on terminal 6 all the time and not gated with the
sleep of the module when DIP switch 2 is on. Any current draw from
terminal 6 will result in reduced battery life. This mode is primarily intended
with switch closure applications with the XBee Digital I/O Adapter with the
external switch in the customer equipment in the normally open position, so
no battery current results until the activating event happens.
When DIP switch 2 is on, the +12VDC at 50mA max is provided at terminal
6. This power is gated by both the sleep of the module and AT command
P3. For this power setting to be on, the XBee module needs to be awake

XBee USB Adapter
Chapter 8
Overview
The XBee USB Adapter provides short range wireless connectivity to any
USB device, with available solutions for both mesh (including ZigBee) and
point-to-multipoint networks. Unlike an embedded wireless module, which
requires design integration and development time, these off-the-shelf
adapters provides instant wireless connectivity to existing USB devices. All
XBee adapters can be used with Digi's ConnectPort X gateways for data
aggregation and IP connectivity
Power requirements
The XBee USB Adapter is a bus-powered device.
Download and install device driver
The XBee USB Adapter requires a device driver, FT232R. This device
driver causes adapter device to appear as an additional COM port
available to the PC. Application software can access the adapter in the
same way as it would access a standard COM port.
To download this device driver, go to this web page and select the
download appropriate for your operating system:
http://www.ftdichip.com/Drivers/VCP.htm
Data retrieval
Retrieving data from XBee adapters is done by issuing a remote AT IS
(Force Sample) command through the XBee API. The API and AT IS
command are described in detail in the XBee ZNet 2.5 (Series 2) RF
Module data sheet. These AT IS commands can be issued via a Python
program that is executed on the gateway. See also the Product Manual for
the XBee Module and the Digi Python Programming Guide.

XBee Wall Router
Chapter 10
XBee Wall Router
Overview
ZigBee technology enables low-cost, low-power networking of sensors,
controllers and other such devices in self-configuring, self-healing wireless
mesh networks. Digi's XBee Wall Router is a small extender used to create
the backbone of a ZigBee network or to expand the range of a ZigBee
network so that other ZigBee devices can seamlessly communicate with
one another. The XBee Wall Router can be used with Digi's ConnectPort X
gateways for data aggregation and IP connectivity.
Part of Digi's Drop-in Networking solutions, the XBee Wall Router helps to
create and/or fortify the infrastructure of a ZigBee network by simply
plugging into standard wall power sockets around a customer facility,
creating a multi-path self-healing network. Installation is easy and
completely unobtrusive.
The U.S. version of the XBee Wall Router includes a built-in mounting tab,
which allows it to be securely screwed into standard wall sockets using the
existing mounting screw hole. This prevents accidental unplugging of the
repeater and reduces risk of theft or vandalism. The XBee Wall Router is
designed primarily to “patch” areas within a ZigBee network where signal
erosion or loss occurs due to distance limitations or air interference. It also
serves to create multiple pathways, increasing the redundancy of the mesh
communications to ensure maximum network reliability.
In addition to ZigBee network extension, the XBee Wall Router also
includes two integrated environmental sensors. Customers using
ConnectPort X gateways have the ability to retrieve data from ZigBee
enabled temperature and light sensors built inside of the product. XBee
wall routers can be used with ConnectPort X gateways, XBee embedded
modules, XBee adapters or XBee sensors to "drop-in" end-to-end device
networks – without the need for a wired network infrastructure.

XBee Sensors
Overview
The XBee Sensor family is a group of Zigbee-enabled, battery-powered
sensors incorporating an XBee module. Part of Digi's Drop-in Networking
solutions, XBee Sensors read real-time data from sensors such as
temperature, humidity, and light. This data can be retrieved and transmitted
through wireless communications in a ZigBee infrastructure. Compact size
and battery power enable XBee Sensors to be dropped into facilities easily
and unobtrusively while providing reliable communications. Applications
include building automation, environmental monitoring, security, asset
monitoring, and more.
Installation is easy: simply insert batteries, add the XBee Sensor to the
ZigBee network, and configure inputs and outputs, using Digi-provided
modules written in the Python programming language. Next, mount the
device in a desired out-of-the-way location and begin collecting data. XBee
Sensors can be used with ConnectPort X gateways, XBee embedded
modules, XBee adapters or XBee Wall Routers to "drop-in" end-to-end
device networks, without the need for a wired network infrastructure.
Sensor options
There are currently two XBee Sensor product options available:
• XBee Sensor /L/T: Integrated ambient light and temperature sensors
• XBee Sensor /L/T/H: Integrated ambient light, temperature, and
humidity sensors
Power options
Alkaline Battery Model: This product is powered by three AA batteries
(1.5V). To install/replace batteries, remove the two outer case screws and

63
Configure XBee radio settings
Basic radio settings control basic operation of the XBee Module in a
ZigBee network.
• PAN ID: Sets the PAN (Personal Area Network) ID, in hexadecimal.
This is the preferred PAN ID for the ZigBee network. All Digi Drop-in
Networking products have a default PAN ID of 0x234. A PAN ID of
FFFF causes the XBee Module to select a random PAN ID.
Otherwise, the specified ID will be used.
•
•
•
•
When a Router or End device searches for a Coordinator on the
ZigBee network, it joins to a parent that has a matching PAN ID. If
that device's configured ID setting is FFFF, the device will join a
parent operating on any PAN ID.
Note: Changing the PAN ID may make your XBee product
inaccessible.
Node Identifier: A descriptive, user-friendly name for the device.
This identifier is returned as part of any Node Discover operations
done on the ZigBee network. Using Node Identifiers for Drop-in
Networking devices makes it possible to reference them by names
rather than their physical addresses. Enter a name of up to 20
characters.
Discover Timeout: Sets the amount of time a node will spend
discovering other nodes when a Node Join or Node Discover is
issued.
Scan Channels: A bit field list of the channels to scan. The Digi
device chooses of the channels when starting the network. In a
Router or End device, the bit field is a list of channels that will be
scanned to find a Coordinator/Router to join.
Scan Duration: Sets the scan duration exponent of the Active and
Energy Scans (on each channel) that are used to determine an
acceptable channel and Pan ID for startup of the Coordinator.
64
Configure XBee radio settings
Advanced radio settings control behavior of the XBee Module at a
more detailed level. Generally, these settings can be left at their
defaults.
• Transmit Power Level: Sets the power level at which the XBee
Module transmits conducted power.
Power Level
Conducted
Power in dBm
Lowest (0)
-10 to 10 dBm
Low (1)
-6 to 12 dBm
Medium (2)
-4 to 14 dBm
High (3)
-2 to 16 dBm
Maximum (4)
1 - 18 dBm
•
Allows Join Time: Determines how long a Coordinator or Router
will allow other devices to join it. If set to 255, devices can join at
anytime. (This setting is supported on Coordinators and Routers
only.)
• CCA Threshold: Sets the CCA (Clear Channel Assessment)
threshold. Prior to transmitting a packet, a CCA is performed to
detect energy on the channel. The packet will not be transmitted if
the detected energy is above the CCA threshold.
• Random Delay Slots: Sets the minimum value of the back-off
exponent in the CSMA-CA algorithm for collision avoidance. If set to
zero, collision avoidance is disabled during the first iteration of the
algorithm.
• Broadcast Hops: Sets the maximum number of hops for each
broadcast date transmission. 0 sets the radio to use the maximum
number of hops.
Serial interface settings
• Baud Rate: The baud rate for the modem serial port.
• Parity: The parity for the modem serial port.
• Flow Control: Enable or disable CTS flow control for the serial port.
• Packetization Timeout: The number of character times of intercharacter delay required before transmission. If set to zero,
characters are transmitted as soon as they arrive instead of
buffering them into one RF packet.
4. If you assigned a Node Identifier, to view it, go to
Configuration > Mesh Network and click Refresh. The new name is
displayed in the Node Identifier field.
