1. Introduction
Thank you for purchasing this Modell-Zug Elektronix product. The Decoder Z83/84 was specifically designed as an
all-in-one digital accessory decoder to provide maximum versatility in the control of model railroad accessories.
Each of the decoder's four channels contain both momentary pulse outputs for controlling signal or turnout
solenoids and continuous switched outputs for supplying power to sidings, lighting circuits, or other accessories. In
this way, each independent channel of the decoder may be used in any one of three modes: Switch only, Pulse only,
or Switch & Pulse. This allows for various combinations of output types to fit the specific needs of a given layout
area without requiring multiple decoder types. And, since the Decoder Z83/84 utilizes the industry standard
Motorola digital data format, it is compatible and interchangeable with products from major manufacturers such as
Märklin, Uhlenbrock, Viessmann and others. Please study the following manual in its entirety to gain full utility and
enjoyment from this Modell-Zug Elektronix product.
