Differences between this library and java version

Hi, 

I'm trying to connect to a devi heater connection - doing this by porting opensdg-java to c# - but I'm getting different results when using this libry compared to the one done by Sonic-Amiga with teh opensdg-java lib.

See thread:
https://github.com/Sonic-Amiga/opensdg-java/issues/1

Any ideas.....?
