So they signify activity in the digital outputs?

The cascading lights last year were not on the digital breakouts, but on the relay module, and that was a "feature" of the default project image and could have been in your code as well I suppose.

So what would cause a cRIO to be pinged yet not communicate with the DS specifically? (I say the DS specifically because I can re-image from the laptop and can ping it via WiFi as well -- thus the problem is limited to the "DS <---> cRIO" connection)
