Re: 2CAN: not detecting CAN traffic
So I re imaged the cRio with the 2CAN plugin selected. However, after the cRio was rebooted and power cycled, the 2CAN still had a red strobe and indicated it could not detect CAN traffic.

Interestingly enough, when I accessed the web dashboard and changed the CAN bandwith to the lowest setting (125kb/s) the 2CAN status light turned green and the web dash indicated that CAN communication was good and error free. However, the web-dash didn't indicate any data for any of the CAN nodes (ie temp, load, etc were all 0) and additionally when I tried to run our code, the cRio was returning CAN timeout and device not detected errors.

At this point I'm thoroughly confused, especially since after all this I reverted to the serial adapter configuration, and it worked perfectly. Does anyone have any insight as to what's going on?
