In the app, you go to settings and then you add the machine and it's IP address. Once that is done, you should be able to add credits and do all the things the app is able to control. If you don't know the ip of the machine, it is manually set on a text file. You need to pull out the MicroSD card out of the Bettor Tito, put it in a computer and edit the ini file that is in there. There's a setting for the ip address, it does not support DHCP, so you have to pick an IP address outside the range of the IP pool used on your router, but obviously still within the same subnet. (i.e. If your pool is 192.168.1.1 to 192.168.1.50, then pick a number like 192.168.1.100)
