The Viking F-1 Replacement Control Board works only on the ORIGINAL 1st Generation Viking F-1 Swing Gate Operator (NOT the F-1NX model). This is a replacement control board for the 1st Generation model ONLY so PLEASE CHECK TO MAKE SURE YOUR OLD BOARD LOOKS THE SAME IS THE ONE SHOWN HERE. (The next generation control boards look completely different)
