I'll add to Eric's answers.
The only required cRIO Modules are an Analog Module in slot 1 (solely for battery feedback), and a Digital Module in Slot 4 (to feed the RSL).
All unused others can and probably should be removed (and the exposed connector covered with the black rubber caps).
If you have a blinking RSL, then your cRIO is working, not fried.
Usually it blinks because it's disabled and can only be enabled by the Driver Station.
A solid Victor orange light is good. It means the Victor is receiving a neutral signal from the cRIO. It'll remain neutral as long as the RSL has a steady blink, because it's disabled.
The control wiring diagram is here:

There are a lot of photos on CD, unfortunately they are embedded in threads for the most part.
I'm not sure which cRIO pinouts you're interested in. The Modules all have connecting Breakouts or Sidecars. Do you want a breakdown of what all those pins do or are used for?
The cRIO status LEDs above the DIP switches should all normally be off except for the "Power".
The "Status" will blink yellow when the cRIO is reset and booting or when it's a brand new cRIO without an image.
