Does the which-protocol get saved away someplace or does it start fresh each power up? I went looking for the v5.10 on an MX chip, but I found v8.08. After a bit of head scratching, I figured out that I had grabbed the wrong board out of the box. My notes say it's a ACE-III. It looks like the same mechanicals. Do you know if the protocol is real-close or just similar enough to use the same name? -- These are my opinions. I hate spam.
