Note Data from Data Carriers designated for ASCII is stored beginning with the smallest offset from the
receive data words.
Read (ASCII/8) (Sequence No. 503 (Hex 01F7))
This sequence is used when the maximum number of Heads to be read from the Carrier is 8. Up to 20 bytes of
data can be read for each Read/Write Head.
