cRIO Does Not Communicate, Yet Can Be Pinged and Re-Imaged

They signify that the default code is rapidly switching the relays. Cute with nothing attached, a bit scary if pneumatics or any other outputs are attached to the module.

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)

Make sure to check the team ID on the DS as well as the IP on the laptop.
