How can I setup 2 ys-27dx with a camera that only has 1 optical port for an L-type fiber cable? The difuser has no slave port like the ys-110 has, so I have been scratching my head on how this is done. You guys sell a dual pack which describes it as one cable per strobe and then they connect somehow together and then onto the camera. Do I need a Y adapter? If so, part number please, if not a special cable or special difuser maybe? Please clarify this, I currently own one and want to know if is possible in order to buy a second one. Thanks.
