(2)Motor start mode

Set how to control the starting of the IDD spindle motor according to Table 5.3. This setting only determines the operation mode when the power supply is turned on or the microcode is downloaded. In both modes, stopping or restarting the spindle motor can be controlled by specifying the START/STOP UNIT command.

(4)Setting of the SCSI interface operation mode

By establishing a short-circuit between the 15 and 16 CN2 setting terminals, the SCSI interface operation mode is forcibly set to the single-ended mode. When this setup terminal is open, the IDD automatically identifies the DIFFSNS signal level on the SCSI bus and the IDD SCSI interface operation mode is set to the operation mode.
