+ = installed

– = not installed

Default setting:

Jumpers SCSI 1 and SCSI 2 inserted, jumpers SCSI 0 and SCSI 3 not inserted = address 6

SCSI address 7 is always reserved for the SCSI controller.

Termination power (TERM PWR jumper)

The TERM PWR jumper sets the power supply for the terminating resistors on the SCSI bus. The

terminating resistors can be provided with power by the drive or the SCSI bus.

Termination power via SCSI bus = TERM PWR not inserted

Termination power via drive = TERM PWR inserted

Default setting:

TERM PWR jumper not inserted = power supply from SCSI bus

Parity checking (jumper PE)

The jumper PE is preset to "Parity Checking Enabled".

Parity check enabled = PE inserted

Parity check disabled = PE not inserted

Default setting:

PE inserted = Parity check enabled
