I'm struggling to connect what I thout would be the easiest fixture

I've got a strobe, the Ayra flash 60 led.
I found a fixture profile but it's not doing what it should: it strobes at the slowest rate conitnuously when the fixture should just blacked out.
Tried to edit the file but one time the strobe remains full on (blinder), the other time it does not react to the 'strobe' button.
Anyone can point me in the right direction to get this fixture profile right?
It's a 2-channel fixture
CHANNEL 1
000-255: 0-100% Dimmer
CHANNEL 2
000-007: Stroboscope blackout
008-247: Stroboscope mode slow - fast
248-255: Sound controlled mode
