I have the CMS router setup.
Only one side is micro adjusted - typically used for joining operations. The in-feed side can be adjusted 'back' from the cutter head. The out-feed fence does not move.
Typically, for using the micro-adjust in a joiner operation, you would place a straightedge against the fence and just touching the cutter at top-dead-center. Tighten the fence at that point and then you can micro-adjust the in-feed side to increase the depth of cut as for use in straightening a bow in a piece.
There is no micro-adjustment on the unit for moving both sides of the fence. There are a few examples on the forum of attachments others have tried to enable a parallel micro-adjustment.
Hope this answers your question -
