Re: Using a star configuation for Jaguars on CAN
It should be possible, but part of what makes CAN better than PWM is the fact you can daisy chain, which simplifies wiring. I think really what is needed is a more robust connector on the Jaguars. Cars use daisy chain CAN, but don't have comm issues because they don't use RJ-11 style connectors. DB-9 would be very robust but is overkill on size/weight.
I'm not sure whether it's simply an issue with the RJ-11 connectors on the Jaguars themselves or the fact we're making our own cables, but few people seem to have an issue with the modular jack RJ-45 connectors on the cRIO and radio, as long as they're using premade cables. Maybe a good RJ-45 connector on the Jaguar instead of the RJ-11?
