SCSI ID Selection
Jumpers at ID0, ID1, and ID2 (pins 3/4, 5/6, and 7/8) select the SCSI address. Each SCSI device on one Host Adapter must have a unique address.

SCSI Bus Addresses*
ID0	ID1	ID2	SCSI ID
OUT	OUT	OUT	O
IN	OUT	OUT	1
OUT	IN	OUT	2
IN	IN	OUT	3
OUT	OUT	IN	4
IN	OUT	IN	5
OUT	IN	IN	6
IN	IN	IN	7

Interface Termination
Jumper installed at W4 (27/28) (Default) - The drive provides termination for the interface lines; onboard termination is electrically enabled.
Jumper omitted at W4 (27/28) - The drive does not provide termination for the interface lines; onboard termination is electrically disabled.

Terminator Power
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

A jumper at WP (Pins 15 and 16) selects the write protect option.


    Jumper      The drive is write protected.
    No Jumper   The drive is not write protected. (Default)

Parity

A jumper at PTY (Pins 17 and 18) selects the bus parity check option.


    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.
