Re: Anderson PowerPole for CAN bus?

Allen,
We like the Victors and will likely use them for this season. There are a variety of other connector solutions available through outlets like Digikey (who is a big FIRST supporter in Minnesota) and others. As Don has pointed out above, solutions need to maintain buss impedance in some fashion (it is a transmission line interface after all.)

Mb,
There is relatively little current flow in this bus so it does not come under the wire gauge rules. Please remember that the those rules relate current protection to wire size. A dead short on the CAN buss will not burn up the wire.

I would use a locking connector of some type that is easy to terminate and difficult (read as 'impossible') to connect backwards. The RJ-11/45 used on the Jaguar is a pretty reliable device, crimpers are available everywhere for cheap and the connectors are easy to get. As always, I tend to discourage solid wire on moving devices but there is plenty of stranded wire options for these connectors. Spend the money for the right connectors and crimper if you want reliable operation.
