following points when creating the receive buffer :"IDENT_DATA"/data type:
● The first element "NUM_IDS" is always of the type "WORD".
● The next element "TAG_DATA" is always of the type "ARRAY". The number of
transponders to be expected ("n") must be entered in the "ARRAY".
The following tables show an example of the structure of the receive buffer
"IDENT_DATA"/data type for the ATTRIBUTES "0x08" and "0x81".
