Controlling Avantis with midi message

Hi there, we have an Avantis on firmware 1.31 and i have gone through the documentation for controlling the board using midi messages including going through the tcp midi protocol documentation.

I am able to get scene recall working so in general i have it working but there are 2 things i cant figure out from the documentation how to do.

I am trying to figure out what midi message to send in order to change a fader level of an input strip and also to press the pafl button for the strip.

Does anyone know what the message looks like for these functions?

Thanks!

Ok so i figured out how to change the fader level of an input channel by sending 3 control change messages in a row but im still having an issue figuring out how to push the pafl button
