Fujitsu MAC3045, MAB3045, MAB3091, MAC3091, MAA3182 manual Output signal for external LED

b.–LED and LED (V): Output signals

These signals actuate the external LED as same as LED on the front panel of the disk drive. The electrical requirements are given in Figure 4.22.

Notes:

1.The external LED is identical in indication to the LED on the front of the IDD. The meaning of indication can be selected with the CHANGE DEFINITION

command. For details of command, refer to SCSI Logical Interface Specifications.

2.Any load other than the external LED (see Subsection 4.3.5) should not be connected to the LED (V) and –LED terminals.

c.-SYNC (-Spindle sync): Input/output signal

The pin CN1-A6, or CN7-10 inputs or outputs the signal for rotational synchronization when the IDD carries out rotational synchronization.

1)Outputs the master signal for rotational synchronization when the IDD is the master of rotational synchronization.
