The drive provides the output BUSY_OUT signal to power a user-supplied activity
LED.
The output indicates the drive is performing a SCSI operation. To use this output,
connect a user-supplied LED cathode to the BUSY_OUT connection, pin 77 on
the SCA Connector (Figure 3-4). The LED anode must be attached to the proper
+5 VDC supply through an appropriate current-limiting resistor.
