Ulip:

The 6022 works with the 'old' Motorola format. Uhlenbrock does make an adapter that will allow you to connect it to your IB. As a stand alone unit, you can add a 6035 and keyboards. Since the accessory format has not changed the 6022 should work with any accessory decoder. The mini keyboard can be used with a decoder set for address '256'.

Welcome to us, Uli.

Welcome to the forum,Rainer.

No, unless you have very many such lamps. That's exactly what this config is good at, and also, to make switching reliable (power is constant regardless of how many locos you runt).

Another way of achieving this is using Viessmann stuff instead of Märklin 6083; Viessmann (and others, LDT, Uhlenbrock) have separate power feed of the decoders.

In order to get the lamps working, you must use "commong ground", connect all brown together.

That was my point. Just connect the browns together, also between 6022 and IB too. Those two units also have a connection inside between both brown connectors; but it's different with some units like CS, Mobstat, and some DCC-units. The warnings read are either false, or conern different units that you have.

The Märlin way is always to have common ground for all circuits, except transformers feeding digital units, and possibly house lights etc. Circuit tracks, turnout lamps, decoupler tracks, level crossings etc all rely on the common ground strategy.

Another tip; M turnout lamps may easily get some surgery; a separe feeding cable to the solenoid and another to the lamp. The lamp fed by a lights transformer, the solenoid from the decoder. 6022 not needed, but still common ground.
