I always make sure both ends of a H+V pol. link have same polarization connected to same chain.
i.e. CH0 to H, and CH1 to V. on both ends...
But is this really needed?
I am now in a situation I don't know how the other end is connected. Preparing a new end but don't know which pol should be connected to what chain?
So, does it has any importance at all?
(would save me a trip....)
