*Mark is printed on Printed Circuit Board (PCB).
The control cable allows for a daisy chain connection of up to four
drives.
The switch block has DRIVE SELECT switched off with the "radial"
option selected. Each drive is shipped with the switch block marked
"R" switched on, resulting in the daisy chain operation. In this
case, input and output signals are enabled when the appropriate
DRIVE SELECT line is activated.
When the switch block marked "R" is switched off, all inout and out-
put signals are enabled even if the drive is not selected.
However, the front panel LED will not be on. DRIVE SELECT must be
activate to light the LED.
