It's always battery issues with the TPMC-8x. I've had no luck with them for this reason.
As for iPad and CP2e.... I suppose if you draw the graphics with VTPro and not use the template graphics, the memory will be greatly reduced. I happened to have a modest Simpl program with a loaded Xpanel and I apparently ran out of memory when I programmed the iPad with the graphics. Crestron also suggested to remove any excess graphics that reside in the program as they all get compiled whether they are used or not.
And for the record... As much as I'd like to hang around these forums all day, I try make every effort to earn a living, so I cannot immediately respond or debate over some topics.
