Factory new switching modules only have the firmware installed, but no configuration set up. Factory new locomotive modules have the motor and headlight preconfigured.
The following steps are necessary to put them into operation:
Log into the model railway Wi-Fi: In the app, look for the menu item Settings/New Modules, call it up and log the CTC module into the Wi-Fi. Your Wi-Fi data (SSID and password) will then be entered in the net.cfg file on the CTC module.
Note: After the upload, the CTC module restarts, i.e., it takes a few seconds until it becomes visible again.
