RoboRIO unable to detect Jaguars wired through CAN

[w8jrt]

We are also having the same issue. We have the pcm and pdp at each end of the network with the jags in the middle. You can see the pcm and pdp but no jags. If you break the network the pdp shows a stale data message on the web browser. Connect it back up and refresh and it's happy again. If you check the box for lighting the light you can see the effect on the pcm and pdp so i know comm is good over the network. Maybe we have the the high/low on the drives crossed? Am I safe in assuming that software in the robo rio is not the problem? Thanks.
