V600/V620 ID Controller Protocol
Auto-read (Hexadecimal/1) (Sequence No. 509)
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. 504 (Read (Hexadecimal/1)).
Receive Data Word Allocation (3rd Operand of PMCR)
The receive data word allocation is similar to that of Sequence No. 504 (Read (Hexadecimal/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.
Polling Auto-read (ASCII) (Sequence No. 510)
This sequence is used when the number of Heads to be read from the Carrier is from 1 to 8.
Send Data Word Allocation (2nd Operand of PMCR)
First word of send
data
+(4(N-1)+2)
+(4(N-1)+3)
+(4(N-1)+4)
+(4(N-1)+5)
Receive Data Word Allocation (3rd Operand of PMCR)
None.
Note 1. Execute Sequence No. 510 before executing Sequence No. 511, 512, 513.
2. Execute Sequence No. 544 (Polling Auto-read Command Processing Cancel) to cancel the polling
auto-read.
3. Retry processing is not performed for this sequence.
