About this app

QDmi is a generic display application for the Zusi 3 railway simulator.

The following functions are available:

- Speed
- PZB, LZB, Indusi, and GNT
- ETCS (currently experimental, without planning area)

- Train data input
- Sifa (safety device)
- Traction force
- Speed ​​step indicator
- Door release
- Pantograph
- Main switch
- Brake pressure
- Position on the track
- Slippage
- Sliding
QDmi automatically selects a suitable speedometer scale (140 km/h, 180 km/h, 250 km/h, or 400 km/h).

The force display is self-calibrating to +/- 100%.

For calibration, the maximum values ​​for each train type must be received at least once. These values ​​are saved and retained after a restart.

PZB/LZB text messages can be used manually or automatically.

As a special feature, you can display the LZB control parameters in the ERA-ERTMS style, which are actually intended for ETCS.

In the menu (wrench icon → network symbol), you can enter the IP address of the Zusi computer. The connection is established when you tap the entered address.

The Zusi computer must be on the same network as the smartphone or tablet! You can find the IP address in Zusi 3 under Configuration → Network.

Outlook:
A Planning Area will also be available for ETCS.
