EPCID_UID Array[1...62] of
Byte
0 Buffer for up to 62 bytes EPC-ID, 8
bytes UID or 4 bytes handle ID.
• 2 - 62-byte EPC-ID is entered at
the start of the buffer (length is set
by "LEN_ID")
• 8-byte UID is entered at the start
of the buffer ("LEN_ID = 8")
• 4-byte handle ID must be entered
in the array element [5]-[8]
("LEN_ID = 8")
Default value: 0x00 ≙ unspecified
