Over very long extension cables (50’) the S4000/S6000 strobe controllers can lose “sight” of the SignaTech resistors in the light. The result will be that the light system will operate sporadically. To correct this simply request an adapter from Ai for the light you are using and place it in line between the strobe controller and the extension cable.
