When we connect to the Roborio we use the address: roborio-5132.local to get to the config site. Where are the talons, pdb and etc? I looked around, and saw online that there was a dropdown arrow on the CAN interface.
I remember looking at the talon versions at one point, but I forgot how to do this.
That might mean the CAN wiring is wrong or disconnected.
Does your PDP and/or PCM have red blinking lights on them?
They should also be listed under CAN on the left side of the WebDash.
