Configurations Options

SCSI ID
Jumpers at Pin 3-4, 5-6, 7-8, & 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.

SCSI ID	Pin 9-10	Pin 7-8	Pin 5-6	Pin 3-4
0 (default)	out	out	out	out
1	out	out	out	in
2	out	out	in	out

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.
