ID Code
Each ASi slave also has an ID code. In AS-interface V2.1, both the I/O code and ID code
are used to identify a slave type. A slave with ID code $A has Extended Code ID1 and
Extended Code ID2. ID1 is used for identification of slave A or B, while ID2 is used as
the subprofile of a slave with ID code $A.
These ID codes and I/O codes are defined by the AS-International Association. The ID
code table is shown below for your reference.

Note: 'R' denotes reserved
Intermixing of V2.0-compliant And V2.1-compliant Slaves
The ASi Master module allows intermixing of ASi V2.0-compliant and V2.1-compliant
slaves, with restrictions on some functions. Any V2.0-compliant slave and any slave
whose ID code is not equal to $A is known as a standard slave. The table below shows
function restrictions when V2.0-compliant and V2.1-compliant slaves are intermixed.
