Note Data for Data Carriers designated for hexadecimal is stored beginning with the largest offset from the
receive data words.
Read (Hexadecimal/2) (Sequence No. 505)
This sequence is used when the maximum number of Heads to be read from the Carrier is 2. Up to 60 bytes of
data can be read for each Read/Write Head.
