Interface Termination
If terminators are installed at RN1 and RN2 (default), the drive provides termination for the SCSI interface. If the terminators are not installed, the drive does not provide interface termination.
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.
Terminator Power
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)
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)
Jumper The drive is write protected. No Jumper The drive is not write protected. (Default)
Jumper SCSI interface parity checking disabled. No Jumper SCSI interface parity checking on. (Default)
The odd-numbered pins opposite SSYNC and MSYNC are ground return lines for the corresponding signals.
