Hi, if it is the same interface as my induction hob have a look at "Partial schematic of right "keyboard"" on this page: http://johannesc.github.io/induction-hob/. The top part with one NPN and one PNP transistor can be used if you have a microcontroller or a USB to serial TTL level board. I hope that this helps!
