Make sure your static addressing is correct
10.xx.yy.6 For non class mate
255.0.0.0
10.xx.yy.2
The xx.yy is your team number so 10.19.86.6 would be our teams IP address.
also its a possibility that the cRio port is striped out and if that's the case you may have to buy a new cRIO.
As far as I know the camera is the only thing that can go into the 2nd port. Hope I could be of help.
