V600/V620 ID Controller Protocol Appendix M
Read (ASCII/2) (Sequence No. 501 (Hex 01F5))
This sequence is used when the number of Heads to be read from the Carrier is 2. Up to 118 bytes of data can
be read for each Read/Write Head.
Send Data Word Allocation (3rd Operand of PMCR(260))
Receive Data Word Allocation (4th Operand of PMCR(260))
Note Data from Data Carriers designated for ASCII is stored beginning with the smallest offset from the
receive data words.
Offset Contents (data format) Data
+0 Number of send data words
(4 digits Hex) 0006 to 000A (6 to 10 decimal)
+1 Number of Heads
(4 digits BCD) 0001 to 0002
+(4(N–1)+2) Unit No. (2 digits BCD) Arbitrary (However, there is a limit for the max-
imum Unit No. depending on the model)
+(4(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.
+(4(N–1)+4) Leading address No.
(4 digits Hex) 0000 to FFFF
