SSP*
Used only as a cable connection for the refer-
ence index signal (REFIND+) (J6 Pin 6, bot-
tom) for sync spindle feature. J6 pin 5 is GRD.
Install a jumper when no cable is attached.
Default is a jumper installed (not applicable to
"NC" models).

LED*
No jumper ever installed. These pins used to
connect a cable for a remote LED indicator. Pin
3 (top, nearest HDA), the anode connection,
connects in the drive to the +5V supply through
a pull-up resistor. Pin 4 (bottom), the cathode
connection connects in the drive to signal com-
mon through the emitter-collector junction of a
transistor switch that controls the LED on/off
condition.
