navico corus bus data rate?

To make the "eavesdropping" contents analysis of a Navico Corus Bus
system a bit easier, I'd like to ask if anybody knows the data rate of
that slightly seasoned bus. avalue of 125 kb/s echoes in the
background, but it could be more or less.

And is the green wire in the Corus cable CanH oder CanL?

Thanks!
