For Olympus, there is a restriction, which is the "Strobeblitz" do not trigger properly. There are fewer flashes triggered as set. Oddly enough, the problem even if you use the Test button on the controller to trigger! By pressing the test button on the flash itself, the number of lightning fires set correctly. For other cameras Olympus as I can the problem, lack of cameras not tested.
You have to modify to the equipment or even solder, to use it on an Olympus nothing.
You can also run multiple Yongnuo YN560-TX, or use on the camera such as a 603. So a YN560-TX on the camera set to trigger and use a second to adjust.
If one uses several Yongnuo YN560-TX but not same to these settings. So you should use only one to set the lightning, because the second YN560-TX is not aware what was adjusted everything and still displays its old settings.
With the Olympus OMD EM 1 can be up to a 320tel second flashes without which one sees the closure of the image. In a 400tel is very little to see from the closure, so little that's still quite usable (up missing then a little). In a 500tel is definitely conclude then already almost almost half is obscured by the image through the closure.
