Note Data for Data Carriers designated for hexadecimal is stored beginning with the largest offset from the re- ceive 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.
