3.4.3.4Activity LED for SCA-2 Connector Versions

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.
