Re: Can Ping Camera But No Livefeed

I'm not meaning to pick on this post, but I see lots of posts about crossover cables.

Just for clarification. Crossover cables are only needed when two ethernet devices are being connected directly and neither of them supports auto-sense. In the FRC kit, that happens very rarely, but it can happen.

Almost all laptop NICs support auto-sense -- they would have to be quite old not to. The cRIO does not, and the camera does not.

This means that if you are connecting the camera directly to the cRIO without using any form of switch, hub, or router, that is when you must use a crossover cable. The rest of the time, the HW will sense that it doesn't have a link and will try with the transmit and receive swapped.
