Receive Data Word Allocation (4th Operand of PMCR(260))
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 (Hex 01FC))
This sequence is used when the maximum number of Heads to be read from the Carrier is 1.
Send Data Word Allocation (3rd Operand of PMCR(260))
The send data word allocation is similar to that of Sequence No. 500 (Read (ASCII/1)).
Receive Data Word Allocation (4th Operand of PMCR(260))
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.
Auto-read (Hex/1) (Sequence No. 509 (Hex 01FD))
This sequence is used when the maximum number of Heads to be read from the Carrier is 1.
Send Data Word Allocation (3rd Operand of PMCR(260))
The send data word allocation is similar to that of Sequence No. 504 (Read (Hex/1)).
Receive Data Word Allocation (4th Operand of PMCR(260))
The receive data word allocation is similar to that of Sequence No. 504 (Read (Hex/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.
