I asked about the difference in the BIM-01-1 & BIM-01-2 & DD told me:

There is no functionality difference between the two. The only difference is a different style of power input and switch, all cosmetic stuff. FYI we do not sell the BIM-01-1 any longer, it’s possible you can find one from a dealer of ours. BTW I don’t see any advantage using the BIM-01-1 both need power and ground plus the signal wire connected........
