In regards to capabilities, I am not sure what configuration you are looking at operating. In regards to capabilities, there are triggers for transitions on the outputs. For the two outputs, you can either set those with Insteon or trigger them based on transitions on the inputs. The transition prevents repeated messages.
If you let me know a little more specifics, perhaps I can be more specific. Check out the utility suite in the download section (free download) to see the capability of the 2×4.
