Dekoder WD-DEC-G

Function: The WatchDog decoder shall be connected between the command station and the first booster. In case the pc will not send every 5 seconds a normal switch command to the WatchDog decoder, the WD-DEC concludes that the model rail way is out of control of the pc. To prevent the non-controlled running of trains the WatchDog decoder disconnects the boosters from the central unit. The rails will be voltage-free and all trains will stop.

Therefore the WatchDog decoder is not only absolutely necessary for exibitional model rail roads. The WD-DEC has been installed for example to every computer connected to the exibition model rail road at Miniatur-Wunderland at Hamburger Speicherstadt/Germany since November 2002. By using a WD-DEC your model rail road can operate without continuous observation at your ease.

The WD-DEC will not only monitor the pc, but also the command station at the same time. If the command station is not reacting to the commands of the computer the WatchDog decoder will go into action.

The WD-DEC accepts Märklin-Motorola- and DCC-commands. The required data format will be adjusted with the implementation of a connector bridge.

The central unit can be connected to the boosters directly via the 5-poles boosterbus (Märklin-Digital, Intellibox, TWIN-CENTER). Is there no 5-poles booster-bus available at the command station (e.g. Lenz Digital plus), the connection to the boosters will be done via the screw-clamps on the WD-DEC.
