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)

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.
