SETTING THE SCSI ID
SCSI devices are identified by a SCSI ID number from 0 through 7 with ID number 7 typically reserved for
the SCSI interface card. The basic rule for assigning a SCSI ID number requires that:
Each SCSI device
have a unique ID number (address) on the SCSI bus. If two SCSI devices are assigned the same ID
number, your computer will not operate properly.
Assigning a SCSI ID to the Drive if you have a PC:
To avoid conflicts with an existing SCSI device and the interface card, choose an unassigned number in
the range of 0-6.
Tip:
Make list of your SCSI devices and their assigned ID numbers to avoid a SCSI ID conflict.
Assigning a SCSI ID to the Drive:
¶ The three SCSI ID setting switches 0, 1, and 2 (#1, #2 and #3) compose a digital switch. Please
execute setting according to the following table.

is OFF in open condition.
*If the personal computer has no other built-in SCSI equipment except this unit, please use the unit
with the factory setting (ID No. 2).
