Gentlemen,
You are both on track with your understanding of the Rutex Plasma THC control. I wish I could help you more with your project, but I have no first hand experience with the Rutex THC controls--only the servo products. Technical support for the Rutex THC control will still have to come directly from the manufacturer--in Australia. Vladimir is the person you want to talk to there. He has sold these THC controls for many years and knows the ins and outs of plasma THC. He is the best person (other than some experienced user in the States) to get answers for your questions.
At present, I don't know anyone who is using it. In the past year that I have been supporting Rutex users in the States, I have not been involved in THC sales or support. So, I recommend you go to the Rutex web site and email Vladimir direct on questions you guys have regarding these products--if you run into a limit in your familiarity with them. Sounds like you are doing pretty good at helping one another, however.
