Jumpers at ID0, ID1, and ID2 select the SCSI address. Each SCSI device on one Host Adapter must have a unique address. Note that there are two identical groups of address jumpers (one on the board; the other on the Option Jumper Block). Use either group for address selection but not both at the same time.

RN1 and RN2 provide active termination for the SCSI interface lines. (Active termination is recommended when multiple drives are used on the same SCSI cable.) The default is RN1 and RN2 installed.
SCSI terminators are installed only in the end devices on the SCSI cable; remove the terminators from each of the other devices. The SCSI Host Adapter card and the last drive in the chain should have terminators.
W1 and W2 select the source of power (+5V) for terminators RN1 and RN2; W3 controls the drive supplying +5V to the bus.
W1 W2 W3
Y N - Drive provides terminator power. (Default) N Y - Host provides terminator pwr via J1 pin 26 to RN1 and RN2
- - Y Drive supplies +5V to the bus via J1 pin 26. (Default)
Jumpers at SP0 and SP1 control the spindle options.
SP0 SP1 N N The drive starts the spindle motor at power-on. (Default) Y N The drive waits for a Start Unit SCSI command to start the spindle motor. N Y Spindle start-up is delayed based on SCSI ID address (12 seconds per ID)
A jumper at WP selects the write protect option.
Jumper The drive is write protected. No Jumper The drive is not write protected. (Default)
A jumper at PTY selects the bus parity check option. The drive always generates parity regardless of this option..
Jumper SCSI interface parity checking disabled. No Jumper SCSI interface parity checking on. (Default)
Jumpers at W10 and W11 control spindle sync termination. This depends on system configuration; i.e., Master Mode or Master Controller Mode.
W10 W11 Yes Yes Slave and Master Sync are terminated. No No Spindle sync not terminated. (Default)
