Dallas iButton codes written on screen reversed. Not left to right but right to left. I see the code engraved on tablet - it is: “5B 0A 0D 00 BE 81 0E 01” and on flipper screen it is: " 01 0E 81 BE 00 0D 0A 5B"
And the silence…
Actually, no problem, if you know this “feature”, but i’m slightly confused, when i try to program some universal key codes into RW1990 in reversed order 
It’s reversed on the writing on the key !!!
The first hex 01 means a Dallas format key and the last 5B is the checksum. Checksum goes last and file/key type goes first. makes more sense, so best way to think is that it’s inverted on the writting on the key.
Yes, agreed.
