John,
I am thinking that the DSC is not receiving power from the PD. When the DSC is connected to the Crio module, but +12v is not applied from the PD, some of the power LEDs do come on through leakage in the module. They do not, however, provide a pullup voltage for digital inputs. The first indication of a problem here is the failure of the robot signal light.
