Setting terminal: CN2 Figures 1 : setting terminal (CN2) 2 4 1 3 6 5 8 7 10 9 12 11 14 16 18 20 22 24 13 15 17 19 21 23 Terminator power supply : Supply (LED Signal) (HDD reset signal) N.C. Force Single Ended : LVD mode Force Narrow : 16-bit SCSI Motor start mode Write protect : write enable SCSI ID : #15 2.2 CAUTION (NP model): 1. The user must not change the setting of terminals not described in this section. Do not change setting status set at factory shipment. 2. Do not change the setting of terminals except following setting pins during the power is turned on. - Write protect: CN2 9-10 3. To short the setting terminal, use the short plug attached when the device is shipped from the factory. 2.3 SCSI ID setting (NP model) Table 1 shows the SCSI ID setting. Refer to Figure 1 for connector position. IMPORTANT When the SCSI ID is set using the external operator panel connector CN1, all pins listed in Table 1 should be open. If any of pins are shorted, unexpected SCSI is set. 1. Set the SCSI ID so that there are no duplicates between SCSI devices on the same SCSI bus. 2. The priority of SCSI bus use in ARBITRATION phase is determined by SCSI ID as follows: 7>6>5>4>3>2>1>0>15>14>13>12>11>10>9>8 Table 1 SCSI ID setting SCSI ID 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 * CN2 1-2 OPEN SHORT OPEN SHORT OPEN SHORT OPEN SHORT OPEN SHORT OPEN SHORT OPEN SHORT OPEN SHORT * Setting at factory shipment 3-4 OPEN OPEN SHORT SHORT OPEN OPEN SHORT SHORT OPEN OPEN SHORT SHORT OPEN OPEN SHORT SHORT 5-6 OPEN OPEN OPEN OPEN SHORT SHORT SHORT SHORT OPEN OPEN OPEN OPEN SHORT SHORT SHORT SHORT 7-8 OPEN OPEN OPEN OPEN OPEN OPEN OPEN OPEN SHORT SHORT SHORT SHORT SHORT SHORT SHORT SHORT 2.4 Setting terminal power supply (NP model) Refer to Table 2 for controlling the supply of power from the drive to SCSI terminal resistance power source (TERMPOW). However, this setting may not be used with NC model. For information on NP type model, refer to Figure 1.

This setting only determines the operation mode when the power supply is turned on. The stopping or restarting the spindle motor can be controlled by specifying the START/STOP UNIT command. Table 3 Motor start mode setting (NP model only) Start timing of the spindle motor Starting of the motor is controlled with START/STOP UNIT command. The motor is started immediately after the power supply is turned on.

Table 4 Write protect setting Write protect Write operation is enabled. Write operation is disable. * Setting at factory shipment CN2 9-10 OPEN * SHORT 2.7 Setting of the SCSI interface operation mode (NP model) By establishing a short-circuit between the 13 and 14 CN2 setting terminals, the bus width for the SCSI interface is forcibly set to the 8-bit bus mode. The 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. Table 5 Setting of the SCSI interface operation mode Operation mode Follows the DIFFSNS signal level on the SCSI bus Single-Ended mode.

Mode settings : NC model, NP model In addition to the previously described settings using setting terminals, the HDD is provided with several mode settings. The mode settings are enabled by specifying the CHANGE DEFINITION command. Table 7 lists the mode settings and their settings at factory shipment.
