The 3 programs that support this - ARC500, PSREdit500 and Win500 - are not RR programs. They are software packages developed by folks who happen to be RR members.
Links to these, and much more information that you will find useful, can be found in the articles below from our wiki (all links are always blue, both here and in our wiki)
This thread will be moved shortly to our scanner software programming forum, where you can ask questions about those 3 packages and get answers from other users...Mike
