API Operation Frame descriptions
XBee/XBee-PRO® S2C ZigBee® RF Module
183
Data Sample Rx Indicator frame - 0x92
Description
When the device receives an I/O sample frame from a remote device, it sends the sample out the
serial port using this frame type (when AO=0). Only modules running in API mode will send I/O
samples out the serial port.
Format
The following table provides the contents of the frame. For details on frame structure, see API frame
format.
Frame data

Number of
samples
15
The number of sample sets included in the payload. Always set to 1.
Digital
channel mask
1
16-17 Bitmask field that indicates which digital I/O lines on the remote have
sampling enabled, if any.
Analog
channel mask
2
18 Bitmask field that indicates which analog I/O lines on the remote have
sampling enabled, if any.
Digital
samples (if
included)
19-20
If the sample set includes any digital I/Olines (Digital channel mask > 0),
these two bytes contain samples for all enabled digital I/O lines. DIO lines
that do not have sampling enabled return 0. Bits in these two bytes map
the same as they do in the Digital channel mask field.
