OC Flap panel MIP737

Hello,

I have a problem with both N1 / SPD REF rotary encoders in ProSim. They seem to only send "-1" value because if I rotate the encoders clockwise or counterclockwise, both do the same and endlessly lower the value in ProSim. That's not very useful, if you see what I mean...

When I check the variables in IOCP Console, I notice that the value is toggling 0-1-0-1-0-1, whatever the direction of the rotation. Strange...

Does anyone here could successfully configure this panel with ProSIm and how ?

Thanks for any help !
