Probably active High but doesnt really matter if you are not getting anything working. If you had the active state set wrong then all that would happen is you would see the LED on the Diagnostics page go out when you activated the switches and it would then just require you to change the active state to the opposite. The emulated is only for simulating things such as switches and other Inputs via your keyboard, used mainly for testing purposes when you dont have real switches hooked up but you need to test them for simulation.
If you want to attach your xml I can have a look and see if I can find a problem.
