Viessmann 5211 turnout decoder (K-83)

Viessmann 5211 decoder

The Viessmann 5211 decoder has eight separately switchable, short circuit
proof, impulse outputs which can be used for example to switch semaphores, turnouts or uncoupling tracks. It is very similar to the Marklin K-83 decoder.

The decoder uses the Motorola data format and so it can be used with the
system Marklin Digital (controllable by the Central Station using the Keyboard
or the Switchboard, too).

The 5211 has to be set to an address, which connects it with 4 succeeding
pairs of switches of a Switchboard, a Keyboard or the Central Station. You can
see it in the table at the end of these instructions. The eight miniature
switches are switchable by using a small screwdriver or a pencil.

Two Pulse outputs are combined in an output pair (red/green). The outputs
are numbered 1 through 4 are each controlled by a push button pair of your
controller. A push on the green button will result in an impulse at the corresponding
green socket of the decoder, and a push on the red button generates an impulse
at the red output. The middle (yellow) connection is the common pole (return).

We recommend that you use the green pulse to set your turnout to straight (or signal to “go”) and red to set your turnout to curve (and signal to “stop”).

As special feature of the Viessmann Decoder is the possibility to supply the switching power separately at the red extra socket “E”. You have the option to use either the digital power supply (the red wire from your track), or the current from an extra transformer.

Warning: You are connecting the brown from the second transformer with the brown from your digital supply. NEVER connect the red ("E") from the second transformer to your digital supply as well. In this scenario that mistake could be made by plugging the red ("E") wire in the other red socket (far left on this picture).

You would effectively "backpower" your digital system and most likely damage it.

Charlie’s Tip: Always disconnect all power before you make any connections.
