The powerline devices (530E) each have for the money really "boring" devices. Boring because the devices work immediately after plugging already perfectly and you really configure anything / need to adjust. The two devices are already paired (recognize at first) and are already encrypted factory. With the optional downloadable software can turn on the encryption (possibly own key assigned.) And which is very nice, off the LEDs on the device permanently - you see nothing, you hear nothing (no whistle), nothing Blinkert.
