The above jumper setting forces the values of Word 1,3,6 and 60-61 in Identify Device data as follows:
DTLA-305040/307045/307060/307075
°
Word 1/3/6 (C/H/S): Remain ship default value
°
Word 60-61 (LBA): 66055248

°
Word 1/3/6 (C/H/S): 4096/16/63
°
Word 60-61 (LBA): Remain ship default value
Notes:
1.
To enable the CSEL mode (Cable Selection mode) the jumper block must be installed at E-F. In
the CSEL mode, the drive address is determined by AT interface signal #28 CSEL as follows:
°
When CSEL is grounded or at a low level, the drive address is 0 (Device0).
°
When CSEL is open or at a high level, the drive address is 1 (Device1).
