b) the DB37 cable isn't connected correctly. There are checks you can do to verify that signals get through the cable correctly.
c) there isn't connection in the cRIO itself, or the module is in the wrong slot (it should be in slot 2).

It could also be a code issue, but I doubt it.

We tested our cable with a multimeter and it read clean. The cRio has the following lights on: "power", "ACT Link", "10/100" and the two lights on the breakout.What could be wrong with the cRIO?

--UPDATE

So we've pretty much established that the cable is further defective after plugging in the sidecar straight into the module and getting the light to..well, light. My only question is that the light was blinking although the jumper was properly installed, is that supposed to happen? Thanks for the help!
