By default, check boxes 12 –14 in the Edit I/O Setup Control dialog box (previous 

diagram) are cleared to create the bit code 000. This configures the eight front 

panel Bits lights to act as activity lights (glow when high) for the eight bit 

addressable digital I/O lines. The Bits lights can also be configured to provide 

information about amplifier status or act as activity lights for any of the other four 

bytes of digital I/O.
