With this app you can manage locomotive libraries, locomotives and locomotive functions, program digital components – and of course control all locomotives with DCC- or Motorola-decoder, as easy and convenient as is only possible with touch-technology.
The digital switchboard Z21 connects your model train unit and your digital locomotives with your iOS device via WLAN. This way you can control the operation on your train layout easily and conveniently from your mobile device.
Model train control was never this easy and convenient: With one swipe of your hand you can scroll to your model of choice in the locomotive library. A slight touch on the headlight symbol and the front and backlights go on. A second touch, this time on the speaker symbol, and the locomotive makes a sound. Drag your finger over the speed indicator and the train accelerates.
The further highlights of the Z21-App
• Control your entire layout with an intuitive, graphic interface and have easy access to the entire scope of functions of your digital locomotives.
• Manage your entire locomotive-library in just one application, including individual locomotive images for an ideal overview.
• Control the digital functions of your locomotives with intuitive function symbols instead of complicated key combinations.
• Create a blueprint of your railway system and control your switches, signals and modules with a single click.
• Download driver cabs and control your locomotives from a real train driver’s point of view.
