Fujitsu MAB3091, MAC3045, MAB3045, MAC3091, MAA3182 manual Each mode setting, CN6

IMPORTANT

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

5.3.2Each mode setting

(1)Setting terminal power supply

Refer to Table 5.2 for controlling the supply of power from the drive to the SCSI terminal resistance power source (TERMPOW). However, this setting may not be used with SCA2 type 16 bit-SCSI (MAx3xxxSC). For information on MAx3xxxSP, refer to Figures 5.2 and 5.3.

Table 5.2 Setting SCSI terminal power supply (single-ended 16-bit SCSI model: MAx3xxxSP)

Supply on/off of SCSI terminating resistor power from IDD	CN6	1-2
Supply off	Open
Supply on	Short	(*1)

*1 Setting at factory shipment

(2)Motor start mode

Set how to control the starting of the IDD spindle motor according to Table 5.3. This setting only determines the operation mode when the power supply is turned on or the microcode is downloaded. In both modes, stopping or restarting the spindle motor can be controlled by specifying the START/STOP UNIT command.

This setting is not provided for SCA2 type 16-bit SCSI model (MAx3xxxSC). For information on MAx3xxxSP, refer to Figures 5.2 and 5.3.
