Base3 Wi-Fi Configuration using the Cab3 APP

With the Base3’s built-in Wi-Fi, you can operate your model railroad using devices such as smartphones and tablets. Wi-Fi works with the Cab3 App for Android and iOS devices. The Base3 can create its own independent Wi-Fi network or join an existing one. Up to 10 Wi-Fi devices can be connected at once.


Configuring your Wi-Fi Connection

The illustration below shows the switch and push-button on the Base3 that assists in configuring the Wi-Fi connection.

  • A – ACCESS POINT or Join To NETWORK switch
  • B – WPS ENABLE push-button
  • C – Orange Wi-Fi Connection status indicator
  • D – Green Wi-Fi Activity indicator


Note: When using “Join to Network” mode, you may experience control lags due to latency in the network when the network is experiencing heavy traffic.



When you do not have a Wi-Fi network, or you do not wish to connect your Base3 to your Wi-Fi network, use “ACCESS POINT”. This mode creates an entirely new network with a SSID of “Lionel Base3 – NNNN”. The “NNNN” represents the last 4 digits of the Base3’s Wi-Fi radio MAC address. This is unique to each Base3.

To select “ACCESS POINT” mode:

  1. Slide the “ACCESS POINT / JOIN to NETWORK” switch to “ACCESS POINT”.
  2. Connect your smart device to your Base3’s Wi-Fi network.
  3. Launch the App to control your layout.



The Base3 can be added to your home’s Wi-Fi network using most wireless routers.

If your wireless router supports WPS (Wi-Fi Protected Setup), you can easily connect the Base3 to the home network so you can control your trains and have internet access at the same time.

  1. Slide the “ACCESS POINT/JOIN To NETWORK” switch to “JOIN To NETWORK” and power the Base3 on.
  2. Press and hold the “WPS” button on the Base3 for two seconds and then press the “WPS” button on your wireless router. The devices will automatically negotiate a secure connection.
  3. Connect your smart-device to your wireless router network.
  4. Open the Cab3 APP and connect to the Base3.


Remember, if your home network is busy, you may experience latency (slower response to commands) when using the Base3 with a wireless router. Also, when connecting the Cab3 APP to the Base3 through a wireless router for the first time, the connection may take a couple of minutes.
