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.
The ST15150WD drive should be configured with a jumper connecting J01 pins 1 and 3 (and no jumper on J01 pins 2 and 4.
Use pins 11 and 12 on the J5 connector to attach the spindle sync cable.
Remote LED connector J5 pin 9(top pin is negative) and 10(bottom pin is positive).
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.
