Motor start delays is 12 times the drive ID number in seconds; i.e. drive ID 0 starts immediately. Drive one starts 12 seconds later, etc. 6 Jumper installed enables Motor Start option. The drive waits for the Start unit command from the host before starting the spindle motor. 5 Jumper installed means entire drive is write protected. 4 Jumper installed means parity checking by the drive is enabled. 3 RESERVED 2 Select terminator power source. In position 1 the drive 1 supplies power to the SCSI bus, pin 26. In position 2 drive supplies power only to its own terminators. (Factory setting) Jumper horizontally between positions 1 and 2 means the drive takes power from the SCSI bus.
