Re: Using a star configuation for Jaguars on CAN
Al,
Thanks for the input. We'll definitely try the six pin connectors in the fall.

I wasn't thinking of terminating each leg of the daisy chain since, as you mention, that would lower the impedance too far. I was thinking of just a 100 ohm resister at the middle of the star (or maybe 50 ohm with nothing on the leg coming from the 2CAN.) It sure isn't ideal from a noise standpoint, though. The active driver would be terrific but beyond what we'd want to take on.

We never considered using UTP (twisted) cable because it's such a pain to use. Untwisting all those pairs and getting them in the right order seems like an error prone process. All of our cable was straight through like they picture in the Jaguar Manual in appendix A. Do you think UTP is necessary?

By the way, we found our terminators were much more reliable when we soldered the resistor on the end of a short pigtail crimped into the connector. That's probably because our RJ11s were designed for stranded wire.
