Write protect

When the write protect function is enabled on NP model, writing to the disk medium is disabled.

Table 5.4

Write protect setting (NP model)

Pin pair 9/10 of CN2

(GND/WTP)

Write protect

Write operation is enabled.

Open (*1)

Write operation is disable.

Short

*1. Set at factory shipment.

For NC model, the function of the write protect setting is not supported.

(4)

Setting of the SCSI interface operation mode

By establishing a short-circuit between CN2-15 amd CN2-16 on NP model, the SCSI interface

operation mode is forcibly set to the single-ended mode. When this setup terminal is open, the

HDD automatically identifies the DIFFSNS signal level on the SCSI bus and the HDD SCSI

interface operation mode is set to the operation mode.

Table 5.5

Setting of the SCSI interface operation mode (NP model)

Pin pair 15/16 of CN2

(GND/DIFFSENS)

Operation mode

Follows the DIFFSNS signal level on the SCSI bus

Open (*1)

Single-Ended mode

Short

*1. Set at factory shipment.

For NC model, the function of the SCSI interface operation mode is not supported, so the SCSI

interface operation mode follows the level of the DIFFSNS signal on the SCSI bus.

(5)

Setting the bus width of the SCSI interface

By establishing a short-circuit between CN2-13 and CN2-14 on NP model, the bus width for the

SCSI interface is forcibly set to the 8-bit bus mode. This setup terminal must be set in order to

guarantee the physical level of the SCSI interface’s upper bus (DB8-15, P1) inside the HDD only

when the top-level bus (DB8-15, P1) for the HDD SCSI interface is not connected to the external

part of the HDD.
