However, I am not sure to this day what the 90 ° - 270 ° adapter differs from. After searching the net, it appeared that the 90 ° adapter takes the output down and the 270 ° adapter upwards (as I did). Unfortunately directs the supplied 270 ° adapter cable from down. There is a lack here of a clear definition of the term. After the images of the deals you can unfortunately not always go as these are only examples never to perform several different items.
