PREPARATION

4. DIP switch

explanation (See figure 3)

A. Parity check (bit 1)

This determines whether or not a parity check is performed on this

unit's SCSI data bus When it is set to OFF, a parity check is
performed..

B. Reserved (RESERVED, bit

2): shai! be set to OFF

C. Reserved (RESERVED, bit

3): shati be set to OFF

D. Mode switching (MODE, bits 4 and 5)

The unit refers to this bit setting to determine the operation mode to
which the unit wi!i be set after Power ON SCSI RESET

E. SCSI terminator (bit 6)

This determines whether or not the drive's internal terminator resistor

is to be used.

NOTES:

•

Mode can be switched by a SCSI command

9 If there are no special instructions for bits 1 to Sin the software

instruction manual, use the factory settings (refer to figure 3).

The internai terminator resistor is "Active Terminator" which is

SCSi-2 recommendation

When another end of SCSI daisy chain is terminated by "Passive
Terminator" which conforms to SCSt'1 standard, it is

recommended to use commonly sold “Passive Terminator
Module" pluging into the vacant SCSI connector of the drive. In
such a case, the internal terminator shall be disabled (bit 6 of DIP
switch shall be set to ON)
