%V (Voltage Supply Monitoring)
This command applies to the XBee SX 868 RF Module.
Displays the supply voltage of the device in mV units.
Parameter range
This is a read-only parameter
Default
N/A
I/O line passing commands
The following AT commands are I/O line passing commands.
I/O Line Passing allows the digital and analog inputs of a remote device to affect the corresponding
outputs of the local device.
You can perform Digital Line Passing on any of the Digital I/O lines. Digital Inputs directly map to
Digital Outputs of each digital pin.
Analog Line Passing can be performed only on the first two ADC lines:
n
ADC0 corresponds with PWM0
n
ADC1 corresponds with PWM1
IU (I/O Output Enable)
This command applies to the XBee SX 868 RF Module.
Enable or disable I/O data received to be sent out UART/SPI using an API frame when AP = 1 or 2 and
when I/O line passing is enabled.
Parameter range
0 - 1
Parameter Description
0 Disabled
1 Enabled

IA (I/O Input Address)
This command applies to the XBee SX 868 RF Module.
The source address of the device to which outputs are bound. Setting all bytes to 0xFF disables I/O
line passing. Setting IA to 0xFFFF allows any I/O packet addressed to this device (including
broadcasts) to change the outputs.
The source address of the device to which outputs are bound. If an I/O sample is received from the
address specified, any pin that is configured as a digital output or PWM changes its state to match
that of the I/O sample.
