hi @plaksnor.
I had already removed b'\xd8 from the pass condition, that was not the problem.
I’ve noticed that whatever i do or try, my control panel is not generating any \x55\x09 codes, also not as part of a \xd8\x08 code even though i did measure those codes when i was connected to F-link.
I am starting to believe that what i’ve measured when conncted to F-link (\x55\x09, \x52\x09 and \xd8\x08 with an \x55\x09 in byte 10 and 11) is somehow for me only generated when connected to F-link.
I am a bit lost at this point and need time to investigate this.
