encoder has not been associated with a decoder, its commands will not be
recognized.
The user or manufacturer may also set “button level” permissions.
Permission settings control how the decoder will respond to the reception
of a valid command, either allowing the activation of an individual data line
or not. The decoder is programmed with the permission settings during
set-up, and those permissions are retained in the decoder’s non-volatile
memory.
The HS decoder has the ability to identify and output a decoder-assigned
identification number for a specific encoder. An encoder’s key, a 40-bit
counter, and permissions are stored in one of fifteen memory locations
within the decoder. The decoder is able to output an 8-bit binary number
that corresponds to the memory location of the encoder’s information.
This provides the ability to identify the specific encoder from which a
signal originated. This identification can be used in various ways, including
systems that record access attempts or in applications where the
originating user needs to be known.
