Re: Using a star configuation for Jaguars on CAN

We went so far as to buy the best RJ10 crimpers we could and buying a RJ10-45 cable tester. We tested each cable before putting it on the robot wiggling around the wire while we were doing it. We still had problems.

You make a good point about the RJ45 connectors not seeming to fail though there are always the unexplained loss of coms on the field so who knows. Maybe they are dropping in and out too?

I love the way the daisy chain cleans up the control board, I just don't like having, in our case, 18 flaky connectors in that chain any one of which can bring down the whole robot.
