SCSI Wide/Narrow Configuration (DDS-4 Drives Only) 2
Settings:
Switch 9 ON = SCSI Wide Operating Mode (default)
Switch 9 OFF = SCSI Narrow Operating Mode
Switch 9 enables SCSI Wide or Narrow operation. By default, switch 9 is
set to ON, enabling SCSI Wide (16-bit) operation. To enable SCSI Narrow
(8-bit) operation, set switch 9 to the OFF position. This allows the DDS-4
drive to terminate the upper byte of the SCSI bus.
Note: Narrow SCSI is not recommended.
Switch 9 is reserved on internal DAT 72 drives.
