I looked up the baud rate of the Black Jaguars, and it matches the cRIO at 115,200 bits/s. (There is no min or max listed, just the typical, so I think it MUST go at this speed.)
Perhaps the VIs are sending a lot more messages than we thought.
I count two sends and two receives in the "Jag Open". Add one more to each if you're in speed mode, or several more in voltage mode.
It appears that data must be requested from the Black Jaguar; it doesn't automatically send the data back. (I don't know why else CAN Receive would require the arbitration field, referred to here as the message ID)
