Set Jaguar device number via cRIO

How many Jaguars do you have connected to the CAN bus?

If not, follow the steps on page 10 of the bdc-comm user's guide and let us know the results.

If you still have multiple Jags on the CAN bus, let us know what you see in bdc-comm.....do you see all the Jags except the one with device id 0?

You may just need to assign a new id to the Jaguar that currently thinks it is id 0.

[EDIT: to answer your question, the enum responding that there's one device with id 0 is (I'm almost positive) a valid response, provided that's the actual situation on the CAN bus]

Well, I've tried resetting the Jaguar's ID, but it has no effect. I even tried replacing it with a different black Jaguar, but no change.
I'm pretty sure 0 is not a valid ID for a device on the CAN network, but I don't know if the host might appear as having an ID of 0 (regardless of whether the CAN bus itself is working or not).
When I connect another Jaguar, the enumeration still only reports a single device with an ID of 0.
Currently I am working with the BDC-COMM, and a USB to Serial device (Keyspan brand). Once I get that working, I'll move back to the cRIO.
