Sleep
mode LED status Meaning
7 On, solid The network is asleep, or the device has not synchronized with the
network, or has lost synchronization with the network
7, 8 On, slow blinking
(500 ms blink time)
The device is acting as the network sleep coordinator and is
operating properly
7, 8 On, fast blinking
(250 ms blink time)
The device is properly synchronized with the network
8 Off The device is in a low power mode
8 On, solid The device has not synchronized or has lost synchronization with the
network
Diagnostics support
The Associate pin works with the Commissioning Pushbutton to provide additional diagnostic
behaviors to aid in deploying and testing a network. If you press the Commissioning Pushbutton once,
the device transmits a broadcast Node Identification Indicator (0x95) frame at the beginning of the
next wake cycle if the device is sleep compatible, or immediately if the device is not sleep compatible.
If you enable the Associate LED functionality using the D5 command, a device that receives this
transmission blinks its Associate pin rapidly for one second.
I/O line monitoring
I/O samples
XBee devices support both analog input and digital I/O line modes on several configurable pins.
Queried sampling
Devices support both analog input and digital I/O line modes on several configurable pins.
The following table provides typical parameters for the pin configuration commands (D0 - D9, P0 - P2).
Pin command parameter Description
0 Unmonitored digital input
1 Reserved for pin-specific alternate functionality
2 Analog input (A/D pins) or PWM output (PWM pins)
3 Digital input, monitored
4 Digital output, low
5 Digital output, high
7 Alternate functionality, where applicable
The following table provides the pin configurations when you set the configuration command for a
particular pin.
