N: Number of Heads

Note Data for Data Carriers designated for hexadecimal is sent beginning with the largest offset from the receive data words.

Auto-read (ASCII/1) (Sequence No. 508)

This sequence is used when the maximum number of Heads to be read from the Carrier is 1.

Send Data Word Allocation (2nd Operand of PMCR)

The send data word allocation is similar to that of Sequence No. 500 (Read (ASCII/1)).

Receive Data Word Allocation (3rd Operand of PMCR)

The receive data word allocation is similar to that of Sequence No. 500 (Read (ASCII/1)).

Note For auto-read (AR), a response is not returned if the number of Heads is not read by the Carrier, the Abort Bit must be turned OFF to terminate the sequence.
