Interface Termination (W4) Jumper installed at W4 (Default) - The drive provides termination for the interface lines; onboard termination is electrically enabled. Jumper omitted at W4 - The drive does not provide termination for the interface lines; onboard termination is electrically disabled. Terminator Power (W1, W2, W3) Jumper installed at W1 (Default) - The drive provides terminator power. Jumper installed at W2 - The host provides terminator power (via Interface Connector J1A). Jumper installed at W3 - The drive provides terminator power (via J1A) to the SCSI Bus. Spindle Control (SP0) Jumper installed at SP0, jumper omitted at SP1 - The spindle motor starts when SCSI �START UNIT� command is received. Jumpers omitted at SP0 (Default) and at SP1 - The spindle motor starts at power-on. Spindle Delay (SP1) Jumper installed at SP1, jumper omitted at SP0 - Spindle motor start-up is delayed, based on SCSI ID (12 seconds per SCSI ID). Jumpers omitted at SP1 (Default) and at SP0 - The spindle motor starts at power-on. Write Protect (WP) Jumper installed at WP - The drive is write protected. Jumper omitted at WP (Default) - The drive is not write protected. BUS Parity Check (PTY)} Jumper installed at PTY - The drive neither generates nor detects parity. Jumper omitted at PTY (Default) - The drive generates parity and has parity detection enabled. Remote LED Open-collector output - Used to drive a user-supplied LED to indicate the drive is active. |
