I tried "mod" Professional Flash ( Connect to Fast Port of K790 )

If connect 1 resistor 4,7k from pin8 to pin9 of fast Port ===> Phone with External Flash ( as same as K750 ) ( External Flash MODE )

but I only received pulse signal from pin2 ( Display on Oscilloscope ) when Focus and Press .

SEE MY IMAGE :

and no signal from Pin7 ( Video/Strobe )

With K750 , Pin7 (Video/Strobe ) is a one shot ( Pulse ) when Use Flash and Press "shot"
