1. Connect your CS3 to the same local network as your iPhone, iPad or Mac.
This can be done by connecting the LAN port of your CS3 to your router with an ethernet cable.
2. Find the IP Address assigned to your CS3.
On your CS3, go to System/Settings.


Note: Do not use the MAC Address, that won't work.
3. Open RailControl Pro.

4. Click Connect to set up the connection.
Once your CS3 is connected, RailControl Pro will remember its IP Address. To connect with a different CS3, go to the CS3 menu item, choose “Connect…” and replace the IP Address.
