|Configuration and Jumper Options
Jumpers at Pin 3-4, 5-6, 7-8, and 9-10 select the SCSI ID.
Each SCSI device on one Host Adapter must have a unique SCSI ID (0-15).
SCSI ID0 is the Default.
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.
