Offset Contents (data format) Data
+0 Number of send data words
(4 digits BCD)
0007 to 0107
+1 Number of Heads
(4 digits BCD)
0001 to 0004
+(14(N–1)+2) Unit No. (2 digits BCD) Arbitrary (However, there is a limit for the
maximum Unit No. depending on the model)
+(14(N–1)+3) R/W Head CH No.
(1 digit BCD)
R/W Head CH 1 designation: 1
R/W Head CH 2 designation: 2
The CD1D must be set to 1.
+(14(N–1)+4) Leading address No.
(4 digits Hexadecimal)
0000 to FFFF
+(14(N–1)+5) Number of write digits
(4 digits BCD)
0002 to 0010
+(14(N–1)+6)
to (14(N–1)+8)
Write data (Hexadecimal) Input in hexadecimal code
Up to 10 digits (max.) can be set
N: Number of Heads
Receive Data Word Allocation (3rd Operand of PMCR)
None.
Note 1. Write data designated for hexadecimal is sent beginning with the largest offset from the send data
words.
2. Always set an even number of digits for the write data.
Auto-write (ASCII/1) (Sequence No. 526)
This sequence is used when the number of Heads to be written to the Carrier is 1.
Send Data Word Allocation (2nd Operand of PMCR)
The send data word allocation is similar to that of Sequence No. 518 (Write(ASCII/1)).
Receive Data Word Allocation (3rd Operand of PMCR)
The receive data word allocation is similar to that of Sequence No. 518 (Write(ASCII/1)).
Note For auto-write (AW), a response is not returned if the number of Heads is not written by the Carrier, the Abort
Bit must be turned OFF to terminate the sequence.
Auto-write (Hexadecimal/1) (Sequence No. 527)
This sequence is used when the number of Heads to be written to the Carrier is 1.
Send Data Word Allocation (2nd Operand of PMCR)
The send data word allocation is similar to that of Sequence No. 522 (Write (Hexadecimal/1)).
Receive Data Word Allocation (3rd Operand of PMCR)
The receive data word allocation is similar to that of Sequence No. 522 (Write (Hexadecimal/1)).
Note For auto-write (AW), a response is not returned if the number of Heads is not written by the Carrier, the Abort
Bit must be turned OFF to terminate the sequence.
Polling Auto-write (ASCII/2) (Sequence No. 528)
This sequence is used when the number of Heads to be written to the Carrier is 2.
Send Data Word Allocation (2nd Operand of PMCR)
The send data word allocation is similar to that of Sequence No. 519 (Write (ASCII/2)).
Receive Data Word Allocation (3rd Operand of PMCR)
The receive data word allocation is similar to that of Sequence No. 519 (Write (ASCII/2)).
Note 1. Execute Sequence No. 545 (Polling Auto-write Command Processing Cancel) to cancel the polling
auto-write.
2. Retry processing is not performed for this sequence.
