I bought this model because of the crosslinkability. The RM makes a very high-quality impression and looks chic. The networking worked in test mode properly. But be careful: I looked at the RM purchased together with the magnetic mount discs. But here (analog GIRA?) Is the adhesive surface on the RM too small and uneven, so that on the first night of RM sparked from the magnetic disk and crashed down. The RM has passed the retest and appears to be undamaged (= good quality). Now I have received a tip from a recession and the magnetic disc mounted on the few points of contact with the RM superglue. The glue dries yet and I hope I can still use the so practical magnetic disks for my RM. However, I find the magnets also borderline heavily, an additional magnetic or slightly larger capacities the product well. If the trick does not work with the super glue, I will write here a supplement.
