16-bit I/O Sample Indicator - 0x83
Description
This frame type is emitted when a device configured with legacy API output— = 2— receives an I/O
sample frame from a remote device configured to use 64-bit source addressing—MY = 0xFFFE. Only
devices running in API mode will send I/O samples out the serial port.
Note This frame format is deprecated and should only be used by customers who require
compatibility with legacy Digi RF products. For new designs, we encourage you to use I/O Data
Sample Rx Indicator frame - 0x92 for reception of I/O samples.
