Re: RoboRIO unable to detect Jaguars wired through CAN

When you flipped did you see the Jags in the roboRIO web-page config?
When we flipped the wiring we saw nothing on the roboRIO web page. Not even the PCM or the PDP.

Anyway it really shouldn't be this difficult. At this point I would just connect the RIO to one Jag only and get that working. Are these out-of-the-box Jags? Where they ever used before? If so were they working on can or pwm?
We took 2 jags out of the robot we used very recently on an off season competition, but we took a new jaguar out of the box and after rewiring we got the same results.
We have not tried PWM

When you connected with BDC-COMM was it over serial or CAN? I mean if you BDC-COMM (rs232) to one Jag, can you discover the second Jag over CAN?
BDC-COMM worked directly with a CAN cable to serial rs232 port directly into an older computer. We haven't tried connecting multiple jags over CAN but I don't see why we wouldn't be able to since that is how we successfully flashed them last year.

You swapped the wires on the cables at the roboRio and at the PCM on the cable back to the Jaguar? You wouldn't have needed to change anything on the cable between the PCM and PDP.
The wires we swapped were in between the Jaguar and the roboRIO itself. The wires themselves are direct and do not directly connect to the PCM.
