Hi,
Does anybody have a picture of the cangate device and it's internals used to correct the time on the RNS-E unit when used in a B5?
i'm looking to build one myself.
It would be greatly appreciated.
Cheers.

I have looked inside a cangate, if you can build one from a picture then your a feckin genius.
It uses a PIC chip that would have to be programmed with the original code.

I was particularly interested to know what PIC it used. There are thousands on the market. The general build of it would be nice to know too.
coding shouldn't be too bad, its binary in to binary decimal converter.

Thing is that you have to first decode the CAN messages to detect which one of the many tens of different message types is the one that carries the time information and modify only that one - so the coding is a "bit" more complex than you make out.

yeah, you can watch the can bus using easysync to watch all the data being transmitted. Like you say, its a very busy line indeed.
still that's not going to deter me from making one.
