SCSI ID Selection

Jumpers at ID0, ID1, ID2 and ID3 (pins 3/4, 5/6, 7/8, and 9/10) select the SCSI address. Each SCSI device on one Host Adapter must have a unique SCSI ID (0-15). SCSI ID0 is the Default.

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.

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)

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.

Remote LED
Open-collector output - Used to drive a user-supplied LED to indicate the drive is active.
