Looks like you'll need to pull out the ohmmeter at it's lowest scale and probe various points to ground. Pay attention to the values you read as they should get smaller as you get electrically closer to the short.

BTW, the specs for the cRIO digital IO module (http://www.ni.com/pdf/manuals/374069e.pdf) indicate that the inputs can tolerate up to 30 Volts. (Not happily for long but it will tolerate it).
