Ah ah! Mine is marked 109457-0001. Additionally, in case there's a difference here, my PCB has 3 jumpers, JP-1, JP-2, and JP-3. On mine, JP-1 is closed with a solder blob, the other two are open. > The number etched on the component side of the PCB is 109202-0001 REV A. Same. Thanks for the sticker number. It's possible they are different internally, and from the comment in one of the mailing list threads about having to mod one of the programs for a specific model (absolute mode vs relative mode) it does seem likely that different units come up in different default modes. -ethan
