Re: can't enum jags

First off, 12 is a lot. I've only tested 9, but it's supposed to work up to 16.

I'll assume that the number of Jaguars is not an issue, that you've updated firmware on all of them, and that they all have power.

You probably have an issue in wiring your CAN bus.
The cables should be straight-pinned.
Make sure your termination resistor is not shorting.

What happens if you switch which Jaguar is the bridge? Do they all have the same issue?

Re: can't enum jags

Check your jaguar IDs and the termination. Using BDCComm, you should be able to move the termination from the first jag to the second and so forth enumerating the bus again with each terminator shift. With each enumeration, the ID pull down should show the newly added Jag. If the Jags are all on the same ID (default ID 1), then you need to reassign them to make them unique.

HTH,

Mike
