There might be a more efficient and elegant way. I toyed around with the conversion for a moment but didn't figure out a working way quickly. Right now I need to integrate the driver and get it working in the System so that the depended application could can be worked on. I might revisit the current conversion code after that and try to find a "better" way. Kind regards Christian
