Enable parity check of SCSI bus data (default).
Disable parity check.
Motor Start option (MTR)
Enable motor start. The drive waits for the Start Unit command from the host before starting the spindle motor.
Disable motor start (default). The drive starts according to the Delay Motor Start option setting as described below.
Delay Motor Start option (DMS) (valid only if the Motor Start jumper is not connected)
Motor start delay equal to the SCSI ID multiplied by 10 seconds plus 3 seconds. 
For example, if the SCSI ID = 2, the drive 
starts in 23 seconds ((2x10)+3 = 23).
Disable the delay motor start option (default).
