Configuration and Jumper Options

Setting the SCSI ID jumpers

Use the J5 connector to set the SCSI ID, install jumpers on the appropriate pins as shown in the illustration.

Terminating the drive

The ST15150WD drive does not have internal terminators or any way of adding internal termination. You must provide external active termination (ANSI SCSI-2 Alternative 2) to the drive when termination is required.

Terminator power

The ST15150WD drive should be configured with a jumper connecting J01 pins 1 and 3 (and no jumper on J01 pins 2 and 4.

Synchronizing spindles

Use pins 11 and 12 on the J5 connector to attach the spindle sync cable.

Additional jumper options on J5.

	Remote LED connector J5 pin 9(top pin is negative) 
	and 10(bottom pin is positive).

Additional jumper options on J4.

	Write protect on (disables writing) jumper pins 1-2.
	Write protect off no jumper on pins 1-2 (default).

Disable parity check jumper pins 7-8 on J4. Enable parity check (default) no jumper on pins 7-8.

Enable motor start. The drive waits for the start Unit command from the host before starting the spindle motor jumper pins 5-6 on J4.

Disable motor start (default). The drive starts according to the Delay Motor Start option setting as described below - No jumper on J4 pins 5-6.

Motor start delay equal to the SCSI ID multiplied by 10 seconds plus 3 seconds - jumper pins 3-4 on J4.
