CAN Analyser -Experiences
digsys:
Looking for feedback / experiences with CAN Analyzers. Mainly machinery, but able to do vehicle (ODB? would be handy -or a separate project).
I am well aware of what is "out there", just seeing what issues users have found / limitations / stay-away from stories :-) Recommended models?

In automotive industry, the defacto standard CAN tool is CANalyser by Vector Instruments. It is very expensive but worth it compared to the cheaper stuff around.
It can decode the CAN packet if you give it the message format in .dbc files.
It has a programming/scrpting language (CAPL) which allows processing of message to respond or even developing tools.
However, it has been designed to be as non-intuitive as you can get. Once someone has shown you how to do things, it is fairly easy. I personally think Vector did this to make more money by forcing you to go on their training courses.
ODB2 has generic codes that all manufacturers must support but most manufacturers use their own specific codes for most useful stuff. Not sure if Vector provide .dbc file for the ODB2 standard.
I have also used Peak Pcan and Ixxat analysers. They can only do the basic capture and log. We could not find any feature to decode the message.
None of the above come with the ODB2 connector. They all come with 9w Dtype. We make our own adapters when we need.

Yup, I know the whole area is a shltmess, is why I'm looking for experiences. My electrics mechanic has 3 units, one is a Vector, all around $5K+, and he is constantly switching between them to get info he wants, and still fails on many occasions.
I was looking at the Kvaser options, at least they are more reasonably priced. May even grab a couple really cheap open-source ones as well .. usually, all I want to see is data integrity / error rates etc I'll likely have to do a bit of my own development work eventually.
Wondering where to start.

I've drooled over Vektor's stuff, but even moreso over neoVI VehicleSpy for a long time. Never bit the bullet and always used my own custom hw to get what I need, even if that was often severely tiring.

Geeeez what a crock of a price. I hope vehicle Ethernet takes off and brings these prices back to reality :-) At those prices, would they ever "pay" for themselves?
