For third-party hardware or software you should consult with the manufacturer. This site is intended more for general help with technologies listed in the forums page (like C# here on this forum). It's unlikely that anyone who regularily responds here would know much about it, but the manufacturer site may have more developer information or you might even be able to find a newsgroup or unofficial site talking about the technology in question. This is especially true since you're asking about application programming interfaces to the hardware, which should be documented either in product documentation for the device or in a separate, downloadable software development kit from the manufacturer's web site.
