Configuration 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.

Interface Termination
An external terminator provides termination for the interface lines.
Suggested end-of-cable terminator: Methode DS2050-01-68D.

+5V to BUS (W3)
Jumper installed at W3 (Default) - Drive provides terminator power (TERMPWR)
  to the SCSI Bus.
Jumper omitted at W3 - Host system provides TERMPWR.

Spindle Control (SP0)
Jumper installed at SP0, jumper omitted at SP1 - Spindle motor starts when 
  SCSI �START UNIT� command is received.
Jumpers omitted at SP0 (Default) and at SP1 - Spindle motor starts at power-on.

Spindle Delay (SP1)
Jumper installed at SP1, jumper omitted at SP0 - Spindle motor start-up delayed
   based on SCSI ID (12 seconds per SCSI ID).
Jumpers omitted at SP1 (Default) and at SP0 - Spindle motor starts at power-on.


Write Protect (WP)
Jumper installed at WP - Drive is write protected.
Jumper omitted at WP (Default) - Drive is not write protected.

BUS Parity Check (PTY)
Jumper installed at PTY - Drive neither generates nor detects parity.
Jumper omitted at PTY (Default) - 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.
