I believe that the serial-CAN implementation does not allow on the fly choice of Can or PWM. The PWM cable provides a heart beat since the jags are operating in untrusted mode. Also my understanding is that there is a different C-RIO FPGA image for can vs PWM control. There are some good threads on Chief Delphi and the First Beta forum on the CAN situation. Also, Luminary Micros have documentation that can be downloaded. 1 week to go until the kick off. Much should be reveled then. In the mean time if a team is considering using CAN, do some homework now. If the serial rate is 115k then there could be update rate concerns especially if there are many jags on the bus. It's not the bit rate alone, Have to consider latency issues. I can remember Dave giving a warning about serialized communications last year when the new controller was being speculated on. I would definitely head his warnings. The serial and Ethernet Can solutions both allow experimentation with out the C-RIO and the driver station by directly communicating with a PC. This brings up safety concerns because there is no E-STOP button in the loop. BE SAFE.
